Unileaflet mitral valve is the rarest of the congenital mitral valve anomalies and is usually life threatening in infancy due to severe mitral regurgitation (MR). In most asymptomatic individuals, it is mostly due to hypoplastic posterior mitral leaflet. We present a 22-year-old male with palpitations, who was found to have an echocardiogram revealing an elongated anterior mitral valve leaflet with severely hypoplastic posterior mitral valve leaflet appearing as a unileaflet mitral valve without MR. Our case is one of the 11 reported cases in the literature so far. We hereby review those cases and conclude that these patients are likely to be at risk of developing worsening MR later in their lives.

Device based closure of the left atrial appendage (LAA) has emerged as a viable approach for stroke prevention in atrial fibrillation(AF) patients with contraindications to chronic oral anticoagulation. One of the most feared complications is device relatedthrombus formation. We present a 66-year-old male with chronic AF who developed a life-threatening intracranial bleed on oralanti-coagulation. He subsequently underwent LAA closure using an Amplatzer muscular ventricular septal defect closure devicefor stroke prevention. However, he was found to have a large thrombus attached to the device a year later. We present a review ofthe various LAA closure devices, importance of periodic surveillance via echocardiography and management options to preventthis complication. Also, the case highlights the importance of contrast-enhance echocardiography in diagnosis of LAA closure devicethrombus.
