Introduction
As the number of surgical and transcatheter valve replacements continues to increase in the aging population, so does the prevalence of paravalvular leak (PVL), the uncommon but life-threatening complication. Although Given known guidelines focus on valvular heart disease and PVL, diagnosis of PVL is arduous and prone to misdiagnosis. Transesophageal echocardiogram (TEE) plays a major role in assessment of the location and severity of PVL. We report a case of an elderly man diagnosed as PVL with help of TEE, and ultimately received interventional transcatheter closure. Signed written informed consent from the patient was obtained for reporting this case.
