Abstract A 34-year-old female with a history of mitral valve prolapse (MVP) was followed over a 10-year period to assess the long-term effects of MVP on left ventricular (LV) function. Despite initial asymptomatic presentation, progressive left silent progression to LV dysfunction. ventricular dilation and mild systolic dysfunction were detected through serial echocardiography. This case high lights the need for long-term cardiac monitoring in MVP patients, even in the absence of symptoms, due to potential silent progression to LV dysfunction.
