ABSTRACT
Objective:
To evaluate the intro-operative transesophageal echocardiography (TEE) for extended septal myectomy in patients with obstructive hypertrophic cardiomyophathy (HCM).Methods:
A total of 56 obstructive HCM patients with extended septal myectomy in our hospital from 2012-01 to 2012-12 were retrospectively studied. The results of pre-operative transthoracic echocardiography, intro-operative TEE and post-operative transthoracic echocardiography were analyzed and compared.Results:
There were 36 male and 20 female patients with the average age of (46.1 ± 11.3) years. The pre-operative width of inter ventricular septal was (26.1 ± 6.9) mm, left ventricular outlfow tract (LVOT) pressure gradient was (87.5 ± 12.5) mmHg. All patients received successful operation, no in-hospital death, no TEE related complication. The removed ventricular septal thickness was at (10.7 ± 2.1) mm, length at (39.1±5.5) mm. Compared with pre-operative transthoracic echocardiography, TEE indicated the immediate drop of post-operative LVOT peak velocity (4.57 ± 0.99)m/s vs (1.68±0.46)m/s and LVOT peak gradient (87.5 ± 34.4) vs (11.3 ± 7.0) mmHg, both PConclusion:
TEE is safe for extended septal myectomy in obstructive HCM patients. It may pre-operatively identify the cause and degree of MR, evaluate the post-operative improvement of LVOT obstruction and MR. Meanwhile, TEE may ifnd the surgical complication for in time correction in relevant patients.
