The mitral valve is a complex structure regulating forward flow of blood between the left atrium and left ventricle (LV). Multiple disease processes can affect its proper function, and when these diseases cause severe mitral regurgitation (MR), optimal treatment is repair of the native valve. The mitral valve (MV) is a dynamic structure with multiple components that have complex interactions. Computational modeling through finite element (FE) analysis is a valuable tool to delineate the biomechanical properties of the mitral valve and understand its diseases and their repairs. In this review, we present an overview of relevant mitral valve diseases, and describe the evolution of FE models of surgical valve repair techniques.

The patient had rheumatic heart disease, which resulted in severe aortic and mitral valve regurgitation. Repair of both valves was performed at 9 years of age. During surgery, the retracted aortic valve cusps required extension with bovine pericardial patches and suture reduction annuloplasty, and the mitral valve was repaired using a Cosgrove-Edwards (Edwards Lifesciences LLC, Irvine, CA) annuloplasty band.

Infective endocarditis is a potentially fatal condition that can present with non-specific symptoms and rare hematologic manifestations, posing significant diagnostic challenges. We report a compelling case of a 67-year-old male with a history of type 2 diabetes, hypertension, and hyperlipidemia who sought medical attention for a five-month history of progressive iron deficiency anemia, accompanied by weight loss, fatigue, and vague constitutional symptoms. Initial extensive workup, including computed tomography of the thorax, abdomen, and pelvis, gastroscopy, colonoscopy, and transthoracic echocardiography, failed to identify an underlying cause.

Background: Cardiac biomarkers are important components for diagnosing perioperative myocardial infarction (MI). Efforts to detect MI by biomarker-release only faced heavy criticism, because cardiac biomarker-release has also been observed in situations that are not always related to cell death (e.g.

Background: Arterial compliance is an independent predictor of diastolic dysfunction. Invasive catheterization can accurately reflect diastolic function. However, studies on the invasive assessment of diastolic function are currently limited.
