Abstract
A 4-year-old male patient, who had discrete subaortic stenosis and underwent subaortic membrane resection (SAM), presented with dyspnea and palpitation 3 months after surgical intervention, transthoracic echocardiography revealed severe mitral regurgitation due to perforation of the anterior mitral valve leaflet.
Learning objectives: Discrete subaortic membrane stenosis is the most common form of subaortic stenosis, definitive therapy is surgical resection, anterior mitral valve leaflet perforation is a rare complication post cardiac surgery, meticulous surgical resection and TEE guidance is required to reduce complications risk.
Keywords: Subvalvular aortic stenosis, discrete membrane subaortic stenosis, subaortic membrane resection, iatrogenic mitral leaflet perforation, severe mitral regurgitation, mitral valve repair
