Intraoperative TEE showed moderate mitral regurgitation with systolic anterior motion of the anterior leaflet causing a mean gradient of 30 mmHg in the left ventricular outflow tract (LVOT).

These athletes showed relatively mild left ventricular hypertrophy (wall thickness, 13-16 mm) in association with nondilated cavity (end-diastolic dimension, 47-50 mm) in the absence of systemic hypertension, as well as mild systolic anterior motion of the mitral valve in one [subject] and ventricular tachycardia in two.
Echocardiography revealed a resting gradient of 60 mm Hg and systolic anterior motion of the mitral valve septal leaflet.
Other features, useful but not necessary in diagnosing HCM, are: 1) mitral valve systolic anterior motion (absent or mild in nonobstructed pattern) (9); 2) anteriorly positioned mitral valve leaflet coaptation (10,11); 3) anomalous anterior insertion of papillary muscles (12,13), 4) diastolic dysfunction.
In addition, many obstructed patients have significant mitral regurgitation due to systolic anterior motion of the mitral valve (10-12).
Obstruction occurs because of mitral-septal contact during systole, and three primary causes promote this systolic anterior motion (SAM).
Obstruction, most commonly due to systolic anterior motion of the mitral valve (SAM) and mitral-septal contact, occurs in 50% of all HCM patients, worsens symptoms and increases mortality.
