Parachute-Like Mitral Valve with Symptomatic StenosisImaging with Transthoracic and Transesophageal Three-Dimensional Echocardiography and Treatment Implications

摘要

Parachute and parachute-like mitral valve are rarely encountered in adults congenital abnormalities in which diagnosis usually relies on detailed echocardiographic examination with special focus on three-dimensional imaging. In children, these valves often coexist with other congenital anomalies such as aortic stenosis, atrial septal defect, hypoplastic left heart syndrome or form Shone complex together with supravalvular mitral ring, subaortic stenosis, and aortic coarctation. We described a woman with moderate stenosis and mild regurgitation of mitral valve diagnosed as congenital parachute-like anomaly during transthoracic and transesophageal examination. Precise recognition of morphology disqualified the patient from percutaneous balloon angioplasty.
