Аннотация
BACKGROUND: Parachute mitral valve (PMV) is a rare congenital anomaly where all chordae tendineae insert into a single papillary muscle, causing stenosis or regurgitation. Adult presentations are uncommon and often underdiagnosed.
CASE DESCRIPTION: A 35-year-old male presented with exertional dyspnea. Echocardiography demonstrated severe mitral stenosis, reduced ejection fraction, a bicuspid aortic valve, and pulmonary hypertension. Intraoperative findings confirmed true PMV. Due to anatomical complexity, a 27-mm mechanical prosthesis replacement was performed successfully, with rapid postoperative recovery.
CONCLUSION: Adult PMV requires high clinical suspicion and often surgical confirmation. Valve replacement is effective in complex cases, emphasizing the importance of early diagnosis and intervention.
