Impact of Septal Myectomy on Left Atrial Volume and Left Ventricular Diastolic Filling Patterns: An Echocardiographic Study of Young Patients with Obstructive Hypertrophic Cardiomyopathy

Septal myectomy in young patients with obstructive hypertrophic cardiomyopathy (HCM) can be performed with low mortality, and leads to excellent improvement in symptoms. Left atrial (LA) enlargement has been associated with exercise intolerance, severity of mitral regurgitation (MR), and left ventricular (LV) outflow tract (LVOT) obstruction in adults with HCM.Young patients (1-22 years of age) who had a septal myectomy for obstructive HCM...
