A 33-year-old patient with no cardiovascular risk factors and no history presented with shortness of breath, palpitations and fatigue. The cardiovascular examination showed an apex beat lateral and inferior displacement and a mitral systolic murmur. The electrocardiogram showed both left ventricular hypertrophy and left atrial hypertrophy. Inflammatory markers were within normal range and blood cultures were sterile. Transthoracic echocardiography showed a severe mitral regurgitation and posterior mitral leaflet prolapse and both left ventricular and auricular dilatation. The transoesophageal echocardiography showed a P3 prolapse with a mobile structure on the posterior mitral valve atrial side suggesting a chordal rupture. The patient had a surgical cure (posterior valve plasty) with good outcomes.
