Adult Presentation of Congenital Mitral Stenosis: The Challenges of a True Parachute Mitral Valve
Abstract
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.
