“…Echographically, compensatory AMVL elongation was noted in all previous reports, usually associated with mitral regurgitation, varying from mild to severe except of 10 cases [3,4,9,[19][20][21]. Other associated congenital heart malformations have been reported, such as aortic bicuspidia [10,22], ostium secondum atrial septal defect [1,13,18], sinus venosus atrial septal defect associated with partial abnormal pulmonary venous drainage into the right atrium [15], single-papillary muscle [23], UMV obstructing the left ventricular out ow [20], and a rare case of the left ventricle endomyocardial brosis diagnosed at autopsy [13].…”

Singular leaflet mitral valve is rare and complex entity that has only been described in a few case reports. It is commonly observed in infancy and combined with symptomatic mitral regurgitation (MR). In most asymptomatic individuals, it is mainly attributed to hypoplastic posterior mitral leaflet and is usually revealed in adulthood by a complication. We present the case of a 30-year-old man who presented with chest pain and dyspnea for two days. The electrocardiogram showed complete atrioventricular block with a beat rate of 30 bpm. Echocardiogram revealed an elongated anterior mitral valve leaflet and an almost completely absent posterior mitral valve leaflet with no MR. Our case is unusual presentation of unileaflet mitral valve which should be investigated even in adulthood as these patients are likely to be at risk of developing or worsening MR later in life, hence, the importance of performing periodic echocardiograms in these patients in order to detect the progression of MR early.

Introduction. Congenital malformations of the mitral valve encompass a broad spectrum of lesions, with an incidence of approximately 0.4% among patients with congenital heart diseases. Case Report. A 45-year-old female was admitted to our institution due to a confirmed mitral valve defect identified via echocardiographic examination. She presented with leg swelling and rapid fatigue. Her medical history includes systemic lupus erythematosus. Upon admission, she was in cardiopulmonary decompensation, with a systolic murmur detected in the mitral valve area, radiating towards the axilla. Transesophageal echocardiographic revealed severe mitral stenosis with moderate regurgitation, without clear visualization of the two cusps. Cardiac computed tomography confirmed a voluminous anterior mitral cusp and a hypoplastic posterior cusp, observed in diastole as a crescent-shaped, characteristic of a unicuspid mitral valve. Follow-up echocardiographic showed progression of mitral regurgitation with circumferential pericardial effusion, necessitating pericardiocentesis. Due to further hemodynamic instability, urgent surgical mitral valve replacement was indicated. The surgery proceeded without complications, but the immediate period was marked by exacerbation of renal impairment, requiring hemodiafiltration on several occasions. Following cardiological stabilization, the patient was transferred to the Nephrology Clinic for further management of renal insufficiency and systemic lupus. Conclusion. It is crucial to emphasize the significance of a multidisciplinary approach for each patient, with particular emphasis on detailed imaging diagnostics to definitively establish a congenital heart disease diagnosis.
