In a preceding article, I wrote about the emotional distress that some patients suffer when they wait inordinate lengths of time for their test results.1 This sequel highlights the other side of the story: what can happen when a doctor is the patient. Because I found no previous article on this aspect of the wait-time issue, the material presented here consists entirely of my experiences as a patient during an academic career that spanned 6 decades. Like most doctors, I have always benefited from an adequate income and always carried adequate medical insurance. Consequently, I haveProfessional Advantages
If the title of this story has you wondering, my wife hasn't left me (at least not yet). She does, however, have a longstanding, unusual, and sporadically debilitating problem with her back. The problem started abruptly more than 30 years ago, at age 46, while she was dressing. Upon raising her right leg to step into her skirt, she experienced excruciating pain across her lower back and collapsed onto the floor. For the next 3 weeks, she spent most of the time in bed, loaded with analgesics, sedatives, and muscle relaxants. In addition to the pain, she complained of an
The physical examination must be carried out with a watchful eye, a sensitive touch, discerning ears, and an alert sense of smell. Above all, what is needed is an alert mind, free of dogma and routine. Each clinical problem, no matter how routine it may appear to be on the surface, calls for an unprejudiced approach. Each possible clue must be pursued; nothing can be taken for granted.” So said Maxwell Myer Wintrobe, the man whose body of work established hematology as a distinct subspecialty and earned him a front-row seat in the pantheon of physician-scientists. His words exemplify his
Heeding the natural history of diseases can improve diagnostic accuracy, promote proper management, and reduce the number of erroneous conclusions.1 Yet with so much emphasis these days on treatment—often before a specific diagnosis is established or even sought—the natural history of most diseases never unfolds. As a result, I dare say that most current practitioners do not consider this aspect of clinical medicine in their approach to patient care. I think they should. Hence, this editorial. In 1962, I helped care for a young boy with homozygous sickle cell disease whose serum bilirubin concentration hovered around 100 mg/dL
Effective communication is the key to success in almost all endeavors. This is particularly important in medical practice, where poor communication fosters poor patient care, sometimes with fatal outcomes. In that light, many medical manuscripts that routinely cross my desk have conspicuous grammatical mistakes, punctuation errors, and confusing sentence structure. But in all fairness, proper use of the English language is not easy and can itself be confusing. There are words, for example, that look wrong to your eye but sound right to your ear. Such incongruity is typical of misused homophones—words that sound alike but differ fundamentally
Some people are born with compassion. Alas, I had it beaten into me.” I recently heard that from an older colleague. The context was the difficulty we shared in approaching end-of-life care for a patient—and his wife. My colleague, a cardiologist, had cared for this patient for more than 30 years, and now the patient, in his 9th decade
Herbert L. Fred, MD, MACP, was 89 years old when he died peacefully at home on 30 December 2018. For nearly 6 decades, he was a renowned and highly honored full-time medical educator at Baylor College of Medicine (BCM), and later at the John P. and Kathrine G. McGovern Medical School at The University of Texas Health Science Center at Houston (UTHealth). He was a prolific author with worldwide influence. His meticulous training of several thousand medical students and internists helped them to become better doctors. Herbert Leonard Fred was
Ray C. Fish (1902–1962) was a leading figure in Houston's natural gas industry and a philanthropist. He believed in the American dream of “opportunity for success.” The Ray C. Fish Foundation was established so that others might be encouraged to broaden man's self-knowledge and to keep the American dream alive. After its founder's death from heart disease, the Fish Foundation granted $5 million to make the Texas Heart Institute a reality. For this reason, the Institute's highest professional award is given in honor of this extraordinary man. The award recognizes
Various techniques for treating tricuspid regurgitation have been described; however, because of scarce data about the long-term outcomes of different repairs, the optimal technique has not been established. We evaluated the effectiveness and durability of artificial neochordae implantation in the treatment of tricuspid regurgitation. From 2009 through 2014, 507 patients underwent tricuspid valve repair at our institution. Of those, 48 patients implanted with artificial neochordae were included in our study. The median age of the participants was 62 years (range, 4–77 yr) and 50% were women. Thirty patients (63%) were in New York Heart Association functional class III, and 11 (23%) were in class II. The cause of tricuspid regurgitation was functional in 33 patients (69%) and rheumatic in 15 (31%). In 46 patients, neochordae implantation was performed in addition to Kay annuloplasty (n=13) or ring annuloplasty (n=33). Forty-two patients were discharged from the hospital with absent or mild tricuspid regurgitation. The mean follow-up period was 44.3 ± 20.2 months. Follow-up echocardiograms revealed that tricuspid regurgitation was absent, minimal, or mild in 38 patients (80.8%), moderate in 7, and severe in 2. Our results indicate that the use of artificial neochordae implantation as an adjunct procedure to annuloplasty leads to effective and durable repair in comparison with conventional techniques for treating tricuspid regurgitation.
We explored the potential clinical value of material separation enabled by dual-energy spectral computed tomography in detecting left atrial appendage thrombi. The study enrolled 24 patients who were scheduled to undergo atrial fibrillation ablation (12 with and 12 without left atrial appendage thrombi). Computed tomograms were acquired in gemstone spectral imaging mode; the densities in the regions of the left atrial appendage cavities, pectinate muscles, and left atrial appendage thrombi were analyzed on monochromatic 70-keV images. Iodine and blood were chosen as the material basis pair; the iodine and blood densities were observed and quantitatively determined from the iodine- and blood-specific material decomposition images. On the 70-keV monochromatic and iodine-specific images, the left atrial appendage pectinate muscles and thrombi appeared as areas of hypodense attenuation. On the blood-specific images, similar areas of high attenuation were observed in the thrombi and cavities, whereas lower attenuation was noticed in the pectinate muscles. The quantitative iodine and blood densities in the pectinate muscles were lower than those in the cavities (P <0.001). The iodine densities in the thrombi were lower than those in the cavities (P <0.001); however, blood densities did not differ significantly between the thrombi and cavities (P=0.192). Compared with the pectinate muscles, the thrombi showed lower blood-density differences (P=0.003) and higher iodine-density differences (P=0.006) in relation to the cavities. Spectral computed tomography-enabled material separation is a novel method for differentiating left atrial appendage thrombi from pectinate muscles. The potential applications of this technology warrant further studies.
Venous thromboembolism is a leading cause of cardiovascular death. Historically, surgical intervention has been associated with high morbidity rates. Pharmacologic therapy alone can be inadequate for patients with substantial hemodynamic compromise, so minimally invasive procedures are being developed to reduce clot burden. We describe our initial experience with using the AngioVac system to remove thromboemboli percutaneously. We reviewed all suction thromboembolectomy procedures performed at our institution from March 2013 through August 2015. The main indications for the procedure were failed catheter-directed therapy, contraindication to thrombolysis, bleeding-related complications, and clot-in-transit phenomena. We collected details on patient characteristics, procedural indications, thrombus location, hemodynamic values, cardiac function, pharmacologic support, and survival to discharge from the hospital. The Wilcoxon signed-rank test was used for statistical analysis. Thirteen patients (mean age, 56 ± 15 yr; 10 men) underwent suction thromboembolectomy; 10 (77%) survived to hospital discharge. The median follow-up time was 74 days (interquartile range [IQR], 23–221 d). Preprocedurally, 8 patients (62%) had severe right ventricular dysfunction; afterwards, 11 (85%) had normal function or mild-to-moderate dysfunction, and only 2 (17%) had severe dysfunction (P=0.031). Percutaneous suction thromboembolectomy, a promising therapeutic option for patients, appears to be safe, and we found it to be associated with improved right ventricular function.
Ascending thoracic aortic aneurysm (ATAA) is typically treated surgically. No commercially available device has been specifically designed for endovascular ATAA repair, and currently, multiple anatomic and technical challenges affect its feasibility. Previously, such repairs have been performed with the patients under general anesthesia. We describe a novel, minimally invasive approach to endovascular repair of ATAA, involving local anesthesia, conscious sedation, and 24-hour hospitalization. Two consecutive male patients (ages, 79 and 54 yr) who had comorbidities underwent percutaneous transfemoral endovascular ATAA repair with use of commercially available endografts. Patient 1 had a saccular aneurysm, and Patient 2 had a pseudoaneurysm consequent to recent surgical ATAA repair. The patients were discharged from the hospital 24 hours after technically successful, uncomplicated procedures. At 2 months, computed tomograms showed no endoleak or stent-graft migration. Our experience shows that minimally invasive endovascular ATAA repair is feasible for selected high-risk patients. We describe the procedure, access and closure devices, and challenges associated with this approach.
Pheochromocytoma, a rare catecholamine-secreting tumor, typically manifests itself with paroxysmal hypertension, tachycardia, headache, and diaphoresis. Less often, symptoms related to substantial hemodynamic compromise and cardiogenic shock occur. We report the case of a 66-year-old woman who presented with abdominal pain. Examination revealed a large right adrenal mass, cardiogenic shock, and severe heart failure in the presence of normal coronary arteries. Within days, the patient's hemodynamic status and left ventricular ejection fraction improved markedly. Results of imaging and biochemical tests confirmed the diagnosis of pheochromocytoma-induced takotsubo cardiomyopathy. Medical therapy and right adrenalectomy resolved the patient's heart failure, and she was asymptomatic postoperatively. We recommend awareness of the link between pheochromocytoma and takotsubo cardiomyopathy, and we discuss relevant diagnostic and management principles.
Acute aortic dissection can be complicated by malperfusion syndromes, including ischemia of the lower limbs. In some cases, delayed correction of leg ischemia leads to reperfusion injury, potentially resulting in renal failure. We describe the case of a 64-year-old woman who presented with acute aortic dissection manifesting itself as lower-limb ischemia. During and after aortic surgery with cardiopulmonary bypass, the patient developed myonephropathic metabolic syndrome. Hyperkalemia was corrected and acute kidney injury was prevented by infusing large volumes of intravenous fluids and administering human atrial natriuretic peptide. Peripheral bypass surgery was unnecessary. This case suggests that restoring blood flow to an ischemic leg by means of adjunctive perfusion during aortic repair with cardiopulmonary bypass is a viable way to overcome the biochemical instability associated with prolonged ischemia, especially hyperkalemia in the early phase of reperfusion.
Aortoventricular fistula, a rare congenital or acquired defect of the aortic wall, is characterized by an abnormal connection between the aorta and one of the ventricles. Symptom severity correlates with the diameter of the fistula and with the acute or chronic timing of presentation. The diagnosis is usually made by using echocardiography, and surgical treatment is necessary to avoid progression to heart failure. We describe the case of a 27-year-old woman who underwent successful surgical repair of an aortoventricular fistula that originated from the right coronary sinus and extended into the left ventricle through the interventricular septum. In addition to the patient's case, we briefly discuss this unusual condition
Congenital complete heart block with concomitant biventricular noncompaction cardiomyopathy has been reported once previously. Although not universal, when restrictive physiology is present, impaired diastolic filling may pose a distinct challenge to pacing during the neonatal period. We present the case of a neonate with congenital complete heart block and biventricular noncompaction that resulted in severe diastolic dysfunction and atrioventricular dyssynchrony. We intentionally used 2:1 ventricular pacing to provide atrioventricular synchrony with every paced beat, and this resulted in hemodynamic and clinical improvement. This unconventional pacing technique may be beneficial in other neonates who have complete heart block and diastolic dysfunction.
Reversible cerebral vasoconstriction syndrome is a rare disorder associated with neurologic symptoms secondary to diffuse cerebral vasospasm. Cardiac involvement in this disease is exceedingly rare. A 50-year-old woman was admitted to our hospital for evaluation of chest pain. During a 3-year period, she had been admitted multiple times because of chest pain and elevated serum cardiac enzymes. Transthoracic echocardiograms showed transient wall-motion abnormalities; however, coronary angiograms revealed no coronary artery disease. At the current admission, she had a thunderclap headache, and cerebral angiograms revealed diffuse cerebral vasoconstriction that improved after verapamil infusion, confirming the diagnosis of reversible cerebral vasoconstriction syndrome. The patient was treated successfully with oral diltiazem and had no recurrence of symptoms. We describe what we think is the first reported case of coronary artery spasm in association with reversible cerebral vasoconstriction syndrome. Future research should be focused on identifying treatment options and defining the mechanisms by which the cerebral and coronary vasculature are affected.
A 63-year-old woman was incidentally found to have a thoracic aortic aneurysm. We performed hybrid repair involving aortic arch debranching and endovascular stent-graft placement. Four months later, an asymptomatic pseudoaneurysm had formed at the aortic conduit–brachiocephalic artery anastomosis. To exclude the pseudoaneurysm, we deployed a Covered CP Stent across the anastomosis through a surgically created right axillary artery conduit. We discuss the patient's case and our choice of treatment.
Pseudoaneurysms of the mitral-aortic intervalvular fibrosa are rare complications that can develop after mitral or aortic valve surgery, endocarditis, or Takayasu arteritis. The optimal timing of surgery to avoid potentially life-threatening complications of pseudoaneurysms has not been established, and watchful waiting has been adopted in specific situations. We describe the case of a 50-year-old man in whom a pseudoaneurysm of the mitral-aortic intervalvular fibrosa developed after aortic root replacement with a homograft. After 13 years of watchful waiting, reoperation was deemed necessary because the pseudoaneurysm had grown to 48 mm and the aortic regurgitation caused by the degenerated homograft had become severe. This case highlights the need for increased awareness of mitral-aortic intervalvular fibrosa pseudoaneurysms and their management.
Acute right ventricular infarction presenting with ST-segment elevation in the anterior precordial electrocardiographic leads is an unusual event. Anterior ST-segment elevation typically suggests occlusion of the left anterior descending coronary artery. It should be recognized, however, that occlusion of a right coronary artery branch can cause isolated ST-segment elevation in leads V1 and V2 on a standard 12-lead electrocardiogram. We describe the cases of 2 patients who presented with acute chest syndrome with isolated ST-segment elevation in leads V1 and V2. Emergency coronary angiograms revealed that acute thrombotic occlusion of the right ventricular marginal branch of the dominant right coronary artery caused the clinical manifestations in the first patient, whereas occlusion of the proximal nondominant right coronary artery was the culprit lesion in the second patient. Both lesions caused right ventricular myocardial infarction. The patients underwent successful primary percutaneous coronary intervention. These cases illustrate the importance of carefully reviewing angiographic findings to accurately diagnose an acute isolated right ventricular myocardial infarction, which may mimic the electrocardiographic features of an anterior-wall myocardial infarction.
Afana and colleagues1 have presented a case that illustrates the complex interaction between transient takotsubo cardiomyopathy (TC) and pheochromocytoma, which merits discussion. Some authors have accepted the idea that catecholamine surges are the biochemical cause of TC.2 However, others view this explanation as simplistic and have suggested additional considerations, as follows. Frequently, patients presenting with TC complicated by hypotension have been empirically treated with those hormones, usually effectively. In addition, among the many patients who have no tachycardia or hypertension but have TC, very few typically undergo studies of catecholamine blood levels, meaning that this
A 59-year-old woman with hypertension, hyperlipidemia, and gastroesophageal reflux reported exertional angina that resolved with rest and nitroglycerin. Nuclear stress test results revealed a small, reversible inferior-wall defect and a left ventricular ejection fraction (LVEF) of 0.67. A coronary angiogram showed diffuse 3-vessel disease. The patient underwent elective 4-vessel coronary artery bypass grafting (CABG) with no complications and was extubated the next day. On postoperative day 2, a routine electrocardiogram (ECG) showed an rSr′ pattern in leads V1 and V2, and ST-segment elevation (STE) in leads V2 through V4 (Fig. 1
A 58-year-old man presented with symptomatic high-degree atrioventricular block and congestive heart failure. His medical history included a bicuspid aortic valve (AV), aortic stenosis, and 3 bioprosthetic AV replacement operations—the last, 25 years before, to place a homograft. At the current admission, the patient underwent pacemaker implantation to treat the heart block. Then, a structural AV abnormality was detected. A transesophageal echocardiogram (TEE) showed paravalvular leak and a new finding: a 1.5 × 1.7-cm pseudoaneurysm at the base of the aortic root, adjacent to the fibrous trigone. The pseudoaneurysm, connected by a tract to the left ventricular outflow tract (LVOT),
