A Rare Case of Bicalutamide-Induced Severe Congestive Heart Failure in a Patient With Advanced Prostate Cancer.

Bicalutamide, a nonsteroidal androgen receptor inhibitor, is an established therapeutic agent for advanced prostate cancer but is associated with severe cardiovascular side effects in rare cases. This case report discusses a rare occurrence of severe systolic congestive heart failure (CHF) in a 68-year-old male undergoing treatment for advanced prostate cancer with bicalutamide, without concurrent use of gonadotropin-releasing hormone antagonists. The patient presented with non-specific abdominal and bilateral foot pain. The initial assessment indicated anemia and severe dyspnea, revealing a significant decrease in left ventricular ejection fraction (LVEF) from 55% to 15% on transthoracic echocardiography (TTE), indicative of severe CHF. Bicalutamide was identified as the likely culprit given the temporal association and lack of other identifiable causes, leading to its discontinuation and initiation of guideline-directed medical therapy (GDMT). A remarkable recovery of cardiac function was subsequently observed, with LVEF improving to 60%. The patient was managed with GDMT, and a gonadotropin-releasing hormone antagonist, degarelix, was later introduced for prostate cancer treatment, along with ongoing cardiac monitoring. The recovery of LVEF and the absence of other etiologies reinforce the likelihood of bicalutamide-induced cardiotoxicity. This report underscores the importance of vigilant cardiovascular monitoring in patients receiving bicalutamide, prompt identification of cardiac dysfunction and possible mechanisms of bicalutamide cardiotoxicity, and the potential for cardiac recovery upon drug discontinuation and initiation of GDMT.

Ultrarapid Development of Ruptured Esophageal Varices in a Patient With a History of Heller Myotomy.

Esophageal varices commonly affect cirrhotic patients as a result of elevated portal system resistance. Blood pools within esophageal portosystemic collateral vessels, which can eventually rupture, leading to life-threatening hemorrhage. To prevent this, cirrhotic patients without a history of varices undergo endoscopic surveillance for varices every 2-3 years. We present an unusual case of variceal hemorrhage in a patient who was seen to have no varices on endoscopic evaluation only a month earlier.

From 60% to 5% in 12 Weeks: A Trastuzumab-Induced Left Ventricular Ejection Fraction Drop.

Trastuzumab is the first-line therapy for human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, trastuzumab is associated with cardiotoxicity. It manifests with an asymptomatic reduction of left ventricular ejection fraction (LVEF) and is reversible after discontinuation. Trastuzumab-induced new-onset acute decompensated heart failure is rare (0.5%). We report a case of a 54-year-old woman who received anthracycline (idarubicin, accumulated dose 400 mg/m2 doxorubicin equivalent) for her acute promyelocytic leukocyte 10 years ago, had no relevant comorbidities or other pre-existing cardiovascular diseases, had maintained normal cardiac function, presenting with new-onset dyspnea at rest and bilateral lower extremities swelling 12 weeks after receiving trastuzumab induction chemotherapy for her newly diagnosed early stage HER2-positive breast cancer. Chest X-ray showed severe pulmonary edema. Echocardiography revealed diffuse left ventricular hypokinesis with LVEF 5%. After other possible etiology of cardiomyopathy, including ischemia, infection, substance, or radiation, were excluded by extensive cardiomyopathy workup, a diagnosis of trastuzumab-induced cardiotoxicity was established. Trastuzumab was discontinued, and the patient's symptom was improved with furosemide. Guildline-directed medical therapy was gradually maximized over three months. Repeat transthoracic echocardiography (TTE) at one-year follow-up after the initial diagnosis shows LVEF 33%, and the patient was referred to an advanced heart failure clinic. This case report demonstrated a rare catastrophic cardiac toxicity effect of trastuzumab and its potential association with remote exposure to anthracycline. Studies have investigated the cardiotoxicity in the concurrent use of trastuzumab and anthracycline therapy. However, how trastuzumab affected patients who were exposed to anthracycline for more than eight years had remained unreported. To our knowledge, no previous detailed case report has described the same clinical scenario as in this case. The case also demonstrates the limitation of the commonly used cardio-oncology cardiovascular risk assessment tool and highlights the importance of individualized cardiovascular risk stratification when deciding on chemotherapy plans.

Pseudomonas aeruginosa: An Unusual Culprit of Left-Sided Native Valve Infective Endocarditis.

Endocarditis refers to infection or inflammation of the endocardium, and various pathogens can be involved in infective endocarditis (IE). Endocarditis is usually caused by bacteremia in patients with risk factors, including IV drug abuse, indwelling central venous or urinary catheters, recent dental infections, and implantable cardiac devices. Pseudomonas aeruginosa (P. aeruginosa) is an extremely rare causative organism in IE, predominantly among IV drug users and involving right-sided valves. Left-sided native valve P. aeruginosa IE without established risk factors is uncommon. We present a case of a 68-year-old male with no traditional IE risk factors who presented with intermittent fevers. Blood cultures grew P. aeruginosa, and transesophageal echocardiography revealed posterior mitral valve vegetation. The patient received broad-spectrum IV antibiotics, which were eventually narrowed down to IV cefepime, guided by culture antimicrobial sensitivities. Although the literature describes various risks for P. aeruginosa IE, it can still occur in the absence of traditional predisposing factors. Due to this organism's rapid resistance acquisition and the complication of septic emboli, an expeditious diagnosis and treatment with antibiotics and/or valve surgery are vital to reducing mortality associated with this entity.

A Case Report of Brugada Syndrome Associated With Physical Trauma.

Brugada syndrome is an autosomal dominant channelopathy that usually affects healthy young males without apparent structural heart disease. It is associated with a spectrum of variable and dynamic clinical manifestations, high risk of life-threatening ventricular arrhythmias, and sudden cardiac death. Our patient demonstrated transient and dynamic EKG changes of both type 1 (coved) and type 2 (saddleback) ST elevation, suggestive of the Brugada pattern that was associated with physical chest trauma and stressful situations. While common triggers like fever and certain drugs are well-recognized, this case illustrates the potential for physical stress and trauma to unmask or aggravate Brugada syndrome, albeit without definitive evidence for a causal link. Ultimately, this report underscores the importance of considering a broad differential diagnosis, including Brugada syndrome, in patients presenting with unexplained syncope or characteristic EKG changes, even when traditional triggers are absent.

Septic Shock Secondary to Tricuspid Valve Vegetation Requiring Surgical Debulking.

Tricuspid valve endocarditis is increasing in incidence owing to the prevalent use of intravenous substances. Although most patients respond well to intravenous antibiotics over the course of six weeks, some patients require surgical intervention. A multilayered approach to diagnosis with both transthoracic and transesophageal echocardiography (TEE) is recommended for optimal diagnosis and management. In this article, we report a case of septic shock resulting from tricuspid valve infective endocarditis in a young woman with a history of intravenous drug use who ultimately required cardiothoracic surgical intervention for tricuspid valve vegetation. The sensitivity and specificity of TEE for vegetation on the native valves are about 96% and 90%, respectively. Timely surgical intervention may increase the likelihood of tricuspid valve repair by preventing further destruction of leaflet tissue. Transthoracic echocardiogram (TTE) and TEE have complementary roles in the diagnosis and evaluation of endocarditis. With this case report, we emphasize the importance of multimodality imaging and early surgical intervention to prevent further embolism and destruction of tricuspid valve leaflet tissue.

The Effects of Bariatric Surgery on Cardiovascular Outcomes and Cardiovascular Mortality: A Systematic Review and Meta-Analysis.

Obesity is a major public health problem that is associated with serious comorbidities and premature mortality. Cardiovascular disease (CVD) is the major cause of morbidity and mortality associated with obesity. Lifestyle modifications, pharmacological therapy, and weight reduction surgery are the major interventions to date available for obesity management. Bariatric surgery has been increasingly utilized as a therapeutic option for obesity. In this meta-analysis, we aim to assess the effects of bariatric surgery on CVD outcomes and cardiovascular mortality. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. PubMed, Embase, Cochrane Library, Google Scholar, and Web of Science were searched until 03/01/2022. Our search included three types of bariatric surgery: Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy, and gastric banding (GB). All were searched in conjunction with "coronary artery disease," "ischemic heart disease," "myocardial infarction," "cerebrovascular accident," "stroke," "atrial fibrillation," "heart failure," "arrhythmias," and "mortality." We included 49 studies meeting the study criteria. Bariatric surgery showed a beneficial effect on coronary artery disease (CAD) (hazard ratio (HR) of 0.68 {95% confidence interval (CI): 0.52-0.91}, p = 0.008), myocardial infarction (MI) (HR of 0.53 {95% CI: 0.44-0.64}, p < 0.01) heart failure (HF) (HR of 0.45 {95% CI: 0.37-0.55}, p < 0.01), cerebrovascular accident (CVA) (HR of 0.68 {95% CI: 0.59-0.78}, p < 0.01), and cardiovascular mortality (HR of 0.48 {95% CI: 0.40-0.57}, p < 0.01). The effect on atrial fibrillation (AF) did not reach statistical significance: HR of 0.81 (95% CI: 0.65-1.01), p = 0.07. Our study, that is, an updated meta-analysis, including the three types of procedure, confirms beneficial effects on the major CVD outcomes, including coronary artery disease, myocardial infarction, cerebrovascular accident, and heart failure, and on CVD mortality. This study provides updated insights into the long-term CV effects of bariatric surgery, an increasingly common intervention for obesity.

A Case of Papillary Fibroelastoma of the Aortic Valve Causing an Embolic Ischemic Stroke.

Papillary fibroelastomas (PFEs) are the second most common primary cardiac tumors after myxomas. They are typically located on the aortic valve and comprise a short pedicle with multiple papillary fronds. PFEs are benign but highly friable in nature. Patients can be asymptomatic or present with severe thromboembolic complications. Echocardiography is the modality of choice for the diagnosis of these masses and surgical resection is indicated even in asymptomatic patients. Here, we have presented a case of a 53-year-old male who presented with a stroke after embolization of a PFE.

A Rare Case of Dilated Cardiomyopathy, Focal Segmental Glomerulosclerosis, and Bell's Palsy in a 29-Year-Old Male After Coxsackievirus Infection.

Dilated cardiomyopathy (DCM) is a severe myocardial disease with diversified etiologies. Coxsackievirus serotype B (CV-B) is a known cause of infectious myocarditis that leads to DCM. The pathogenesis of CV-B myocarditis is complex and involves a combination of tissue destruction from viral proliferation and host immune response. Diagnosis is based on clinical findings and the presence of post-infection elevated titers of IgM antibodies to CV-B. Echocardiography is an important imaging modality that plays a key role in diagnosing DCM. Rare complications of coxsackievirus infection may include facial paralysis and chronic kidney disease with nephrotic syndrome. Here we present a rare case of a 29-year-old-male with recent Bell's palsy who presented with new-onset heart failure with left ventricular ejection fraction of 5% and focal segmental glomerulosclerosis nephrotic syndrome in the setting of elevated antibodies to CV-B.

Mitral Leaflet Flail as a Late Complication of Infective Endocarditis: A Case Report.

Infective Endocarditis (IE) refers to an infection of the endocardial surface of the heart which leads to a wide array of complications, including heart failure, perivalvular abscess, metastatic infection, septic embolization, mycotic aneurysms, neurological and renal complications. Mitral leaflet flail (MLF), defined as a failure of leaflet coaptation with the rapid systolic movement of the involved leaflet into the left atrium, is a rare complication of IE which can lead to severe mitral regurgitation. Echocardiography plays a key role in making its diagnosis with transesophageal echocardiograms (TEE), providing greater sensitivity and specificity compared to transthoracic echocardiograms (TTE). MLF is often misdiagnosed, or diagnosis is delayed due to its presentation with non-specific cardiac symptoms. However, early diagnosis with echocardiography and prompt surgical correction leads to improved long-term survival. Here we have presented a case of a 71-year-old female with a past medical history of IE nine years ago who was referred to the cardiology clinic for one month of exertional dyspnea. TTE showed severe mitral regurgitation, and subsequent TEE confirmed flail mitral leaflet.

Staphylococcus lugdunensis Infectious Endocarditis Complicated by Embolic Stroke After Colonoscopy in a 58-Year-Old Female.

There are a significant number of colonoscopies and esophagogastroduodenoscopies (EGDs) done in the United States every year and post-endoscopic infections are frequently seen. Data demonstrating causality between endoscopic procedures and infectious endocarditis (IE) or that antibiotic prophylaxis prior to endoscopic procedures protects against IE is still lacking. Here we have presented the case of a patient who underwent diagnostic colonoscopy as part of a malignancy workup and was later found to be septic with Staphylococcus lugdunensis bacteremia and had IE. We hypothesized that the infection was most likely contracted during colonoscopy as a result of bacterial translocation from the perineal region to the bloodstream. This case report highlights the need for further studies investigating the efficacy of prophylactic antibiotics in reducing the risk of IE after colonoscopies.

Mysterious Left Atrial Mass in a Patient With Metastatic Prostate Cancer.

Cardiac tumors (CTs) are a rare group of disorders that encompass a broad set of masses. They are subclassified into neoplastic and non-neoplastic lesions. Neoplastic lesions can be further subdivided into either primary cardiac tumors (PCTs) or secondary cardiac tumors (SCTs) which are metastasis to the heart. Cardiac myxomas are the most common pathological type of benign PCT followed by rhabdomyomas, papillary fibroelastomas, fibromas, lipomas, and leiomyomas. Here, we present a case of a patient with left atrial mass in the setting of stage IV prostate cancer. We have used transthoracic echocardiography (TTE) and transesophageal echocardiography (TEE) for characterization and differential generation. Our findings are presented in high-quality imaging and video and our top differentials include PCT, thrombi, and metastasis. Although a full diagnostic workup was not completed due to limitations in diagnostic tests available, metastasis to the heart could not be excluded due to the high staging and extensive sclerotic involvement of this malignancy. We emphasized the importance of multimodality imaging, e.g., TTE, TEE, cardiac magnetic resonance (CMR), and cardiac computed tomography (CT) in the workup of incidental cardiac masses and differential refinement.

COVID-19 Pneumonia Precipitating Acute Anterior Wall Myocardial Infarction With Large Left Ventricular Apical Thrombus.

Initial reports suggest an increased thrombotic risk in coronavirus disease 2019 (COVID-19). We present a case of COVID-19 pneumonia that precipitated chest pain, an acute anterior wall ST-elevation myocardial infarction on the fifth day of hospitalization resulting in large left ventricular apical thrombus.

Uric Acid as a potential biomarker of pulmonary arterial hypertension in patients with sickle cell disease.

Serum uric acid (UA) is emerging as a strong and independent marker for pulmonary arterial hypertension (PAH). PAH is well recognized as a life threatening complication of sickle cell disease (SCD). However, the association between UA and PAH in SCD is unknown. We reviewed electronic medical records (EMR) of 559 consecutive adult SCD patients from Kings County Hospital Center (KCHC) between January 2005 and February 2010. Patients (n = 96) with measurement of UA in close temporal proximity to the transthoracic echocardiography (TTE) were identified. PAH was defined as pulmonary artery systolic pressure (PASP) ≥30 mm Hg. Patients (n = 16) with other risk factors which may cause PAH and chronic renal insufficiency were excluded. In 18 patients, TTE could not measure PASP. Finally, 62 patients were selected. Statistical analysis was performed using Student t tests, Pearson correlation coefficient and multivariate regression analysis. Out of 62 patients, 30 had PAH. Patients with PAH had a higher UA level (8.67 ± 4.8 vs. 5.35 ± 2.1, P = 0.001). We found strong positive correlation between the UA level and PASP (r = 0.71; P < 0.0001). This correlation was independent of diuretic use. UA could be a potential marker for PAH in SCD. However, its' prognostic and pathophysiologic role in SCD patients with PAH needs to be further investigated.

Prevalence of hepatitis C virus infection in patients with cardiomyopathy.

Chronic hepatitis C can be associated with extrahepatic manifestations; thus, we explored the association of this viral infection with dilated cardiomyopathy in a group of sixty-three patients with a cardiac ejection fraction of less than 40% determined by an echocardiogram in a prospective study. Two of the forty-one patients with non-ischemic cardiomyopathy (4.8%) had serum antibodies to the hepatitis C virus and one of those had hepatitis C virus RNA (2.4%) in serum, consistent with chronic hepatitis C. One of the 22 patients with ischemic cardiomyopathy (4.5%) had serum antibodies to the hepatitis C virus but the hepatitis C virus RNA was not detected in their serum, consistent with prior infection but not chronic hepatitis C. In this study, chronic hepatitis C was not prevalent in the group of patients, although the only patient with chronic hepatitis C had non-ischemic cardiomyopathy. As a genetic predisposition to develop cardiomyopathy secondary to chronic hepatitis C has been suggested to be relevant in this type of complication, studies that include different racial and ethnic groups are warranted, as treatment of the hepatitis may lead to resolution of the cardiomyopathy.
