Pericardial Effusion as a Complication of Severe Primary Hypothyroidism.

Large pericardial effusions with associated cardiac tamponade are a rare manifestation of hypothyroidism. We present the case of a 63-year-old female with chronic heart failure and newly diagnosed hypothyroidism, who presented to her primary care physician complaining of progressively worsening dyspnea. Chest radiography showed cardiomegaly and transthoracic echocardiography (TTE) revealed a large pericardial effusion with tamponade physiology. An emergent pericardial window was performed, resulting in an improvement in left ventricular systolic function. Pericardial tissue biopsy was normal. Thyroid function tests were consistent with severe primary hypothyroidism. After inpatient treatment with intravenous levothyroxine and interval resolution of symptoms without recurrence of effusion, the patient was discharged home on oral levothyroxine therapy. Close follow up with surveillance echocardiography was planned. While metabolic disorders are seldom thought of as an etiology, it is imperative for clinicians to recognize hypothyroidism as a cause of the pericardial effusion. It is one of the few reversible causes and delay in treatment can result in fatal sequelae.

Case Report: Non-ischemic Papillary Muscle Rupture due to MRSA Myocarditis with Concurrent Thromboembolic Myocardial Infarction Secondary to Infective Endocarditis.

Non-ischemic papillary muscle rupture (PMR) is rare. PMR caused by myocarditis in the presence of concurrent infective endocarditis (IE) and myocardial infarction (MI) has not been described. We report a 46-year-old male with recurrent MRSA bacteremia who presented in septic shock and suffered cardiac arrest. Echocardiography revealed acute mitral valve regurgitation resulting from posteromedial PMR. An intra-aortic balloon pump was implanted. Angiography revealed thrombotic occlusion of a small distal left circumflex artery. Emergent mitral valve replacement surgery was performed. MRSA myocarditis and IE were diagnosed by tissue cultures. Coexistence of myocarditis, IE, and MI poses a challenge in determining etiology.

COVID-19 and Cardiovascular Disease: A Comprehensive Review.

Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has become a pandemic that impacted the lives of billions of people worldwide. Angiotensin-converting enzyme 2 (ACE2) receptor act as a gate for viral cell entry through binding to virus S-protein. Cardiovascular patients are thought to be more susceptible to severe COVID-19 infection due to overexpression of ACE2 receptors in these patients. There is a growing body of evidence suggesting worse outcomes and increased mortality among COVID-19 patients with preexisting cardiovascular diseases. SARS-CoV-2 is capable of causing a wide range of cardiovascular diseases including myocarditis, heart failure, arrhythmia, myocardial ischemia and venous thromboembolism. Drug-disease interaction in COVID-19 patients with preexisting cardiovascular conditions has become a major concern. In this review, we discuss different aspects of the relationship between COVID-19 and the cardiovascular system along with a brief pharmacological overview.

Post-Complex Myocardial Infarct Pseudoaneurysm Rupture and Subsequent Complications.

Ventricular pseudoaneurysm is an uncommonly encountered complication of myocardial infarction (MI) in the era of percutaneous coronary intervention. Its presentation can be very non-specific, and diagnosis requires a high index of suspicion. Urgent surgical repair is generally warranted to prevent potentially catastrophic complications. We present a case of patient who presented several days after his index MI. He was ultimately diagnosed with a ruptured pseudoaneurysm, and despite best efforts had a complicated hospital course.

Cardiovascular Risk Factors and Echocardiographic Findings in a Predominantly Black Population with Rheumatoid Arthritis and Heart Failure.

Among White rheumatoid arthritis (RA) cohorts, heart failure with preserved ejection fraction (HFpEF) is the most prevalent type of heart failure (HF). We aimed to assess the type of HF affecting Black RA patients. 64 patients with RA-HF were compared to age-, sex-, and race-matched RA patients without HF. Left ventricular ejection fraction (LVEF), wall motion abnormalities, left ventricle (LV) mass, and wall thickness were reviewed. 87.3% were Black, 84.4% were women, with a mean age of 69.6 ± 1.38 (± SEM) and BMI (kg/m 2) 29.6 ± 1.07. RA-HF patients had higher rates of hypertension (HTN), chronic kidney disease, and atrial fibrillation. 66.7% had ≥3 cardiovascular risk factors compared to RA patients without HF. 2D-echocardiograms of RA-HF revealed that 62.3% had LVEF ≥50%, 37% had diastolic dysfunction, and 43.1% had wall motion abnormalities. LV mass and relative wall thickness measurements indicated LV eccentric remodeling. The odds ratio for HF was 4.7 (1.5-14.53 CI), p<0.01, among RA-HTN group and 3.5 (1.091-11.7 CI) p<0.01 among smokers. In our predominantly Black RA-HF patients, HFpEF was the most common type of HF. HTN was associated with the highest OR for HF. Eccentric hypertrophic remodeling, a known poor prognostic indicator for cardiovascular events, was found. Further studies are required to confirm our findings.

Telescoping Stents to Maintain a 3-Way Patency of the Airway.

Background: Central airway obstruction near the right upper lobe (RUL) airway orifice poses a dilemma for the clinician. Maintaining ventilation to the right middle and right lower lobes is of utmost importance. However, preserving ventilation to the RUL is desirable as well especially in patients with significant dyspnea. Case presentation: In this case report, we describe telescoping 2 covered self-expanding hybrid stents to relieve airway obstruction while maintaining RUL ventilation. Conclusions: Review of current literature revealed several additional documented approaches to overcome this challenge. The choice of intervention needs to be deliberated based on the available stents, delineation of the airway obstruction, and the patient's anatomy.

Cardiac Tamponade Unmasking Recurrent Ovarian Cancer.

Pericardial disease is a common manifestation of malignancy. Gynecologic malignancies such as ovarian cancer rarely present with cardiac involvement. Cardiac tamponade may be the initial presentation of malignancy in as many as half of pericardial disease cases. We report the case of a 60-year-old female with known ovarian adenocarcinoma, who achieved initial success with tumor debulking and adjuvant chemotherapy but was lost to follow-up. She presented again three years later with new-onset dyspnea and described a syncopal episode. A chest radiograph showed an enlarged cardiac silhouette and bilateral pleural effusions. Transthoracic echocardiography revealed a large pericardial effusion with diastolic collapse of the right atrium and ventricle, consistent with tamponade physiology. Subxiphoid pericardiocentesis and pigtail drain were placed under fluoroscopy with resolution of symptoms and no recurrence. Neoplastic etiology was confirmed by immunocytochemistry on cell block positive for PAX-8. As an adjunct or alternative to cytologic evaluation, diffusion-weighted magnetic resonance imaging and calculation of the apparent diffusion coefficient can be used to differentiate between malignant and benign effusions. Malignant pericardial effusion in ovarian cancer is a treatable oncologic emergency where timely diagnosis and management may facilitate palliation and prolong life.
