Their clinical data were analysed retrospectively. All the patients had drug-refractory symptoms and left ventricular outflow tract (LVOT) obstruction with a resting or physically provoked gradient of ≥50 mmHg. Preoperative transthoracic, intra-operative transoesophageal and postoperative transthoracic echocardiography was performed to assess LVOT gradients, septal thickness, LVOT diameter, mitral valve function, etc. Systolic anterior motion (SAM) of the anterior mitral valve leaflet had been detected in all preoperatively.","tracks":[]}
