Gerbode defect, an anomalous connection between the left ventricle and right atrium, is often congenital but can be acquired or iatrogenically formed. We present an exceedingly rare case of this defect associated with multiple valve perforation in an otherwise healthy patient with bicuspid aortic valve and endocarditis.

Dipyridamole nuclear myocardial perfusion imaging is a safe and useful modality for assessing myocardial ischemia. It is the modality of choice for cardiac risk stratification in patients who are unable to exercise. Intravenous dipyridamole causes coronary vasodilation and may result in heterogeneity of coronary blood flow in significant coronary artery disease.

Introduction Male and female sexual dysfunction is frequently found in patients with hypertension. Many studies indicate that this is found more frequently in patients treated with beta-blockers rather than due to hypertension itself; however, almost all studies have been done on male population. This study aims to study the effect of two commonly used beta-blockers on sexual function of a hypertensive female patient.

CREST (calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia) syndrome, also known as the limited cutaneous form of systemic sclerosis (lcSSc), is a multisystem connective tissue disorder often manifesting as a consequence of superimposed autoimmune hepatitis. Herein, we present a case of a 40-year-old female with a past one-year history of hepatitis C presenting with the chief complaints of progressive thickness and tightness of the skin of hands and face and dysphagia for the past three months, along with arthralgia of the hands for the past two months, suggestive of CREST syndrome. Through this case, we intend to emphasize the association between extrahepatic manifestations and the emergence of autoantibodies in patients with hepatitis C virus (HCV) infection and discuss the clinical relevance of the autoantibodies in extrahepatic disorders, in our case, CREST syndrome.
