Correction of Left Ventricular Outflow Tract Obstruction Caused by Anomalous Papillary Muscle and Subaortic Membrane
This paper presents a case study of a 30-year-old male patient
with dyspnea on exertion had echocardiographic diagnosis of aortic
subvalvar stenosis. Discrete mitral regurgitation and aortic valve
dysplasia with mild to moderate insufficiency and hypertrophic
cardiomyopathy were also noted. During surgery, a rare condition
was identified: presence of papillary muscle anomaly associated
with the subaortic membrane as a cause of obstruction of the left
ventricular outflow tract. With the resection of these structures and
a mitral valve annuloplasty, the patient evolved with a significant
improvement of clinical condition and heart failure, with no residual
mitral insufficiency.
