Although most cardiovascular abnormalities detected in health screenings are asymptomatic, some of them may indicate clinically significant valvular heart disease. We present a case of mitral regurgitation due to mitral valve prolapse identified through routine cardiac auscultation. A 60-year-old asymptomatic man presented with a newly detected systolic murmur at the apex. Echocardiography confirmed severe mitral regurgitation, and exercise stress echocardiography revealed exercise-induced pulmonary hypertension. Given these clinical findings, surgical intervention was recommended. Based on literature-based considerations, this case highlights a viable role for auscultation in health checkups to identify valvular heart disease and guide treatment.
