Isolated Parachute Mitral Valve and Calcified Papillary Muscle in a 70-Year-Old Female: Case Report

The parachute mitral valve (PMV) is a rare congenital cardiac defect in which all chordae tendineae are attached to one papillary muscle, giving the valve its parachute-like appearance. This anatomical defect can result in mitral valve stenosis or regurgitation, which can impede normal blood flow. The diagnosis is often shown by echocardiography, which reveals the valve's unique features. Papillary muscle calcification is an uncommon echocardiographic condition mainly attributed to advancing age, cardiac ischemia, and degenerative valve disease, and its incidence in relation to PMV is not well established. PMV treatment depends on the severity of the condition, with severe instances frequently necessitating mitral valve repair or replacement. It is estimated that approximately two-thirds of those with PMV will require surgical treatment. In our instance, a 70-year-old patient was diagnosed with isolated PMV and calcified papillary muscle during routine echocardiography as part of high blood pressure evaluation. This case demonstrates the diagnostic and therapeutic difficulties related to PMV, particularly if patients are asymptomatic, and emphasizes the importance of continued monitoring and individualized treatment options.
