Abstract:
Objective: To summarize the mid-term effect of modified extended Morrow procedure in patients with hypertrophic obstructive cardiomyopathy (HOCM) combining sub aortic valve obstruction and mid left ventricular obstruction. Methods: We studied 34 consecutive HOCM patients with sub aortic and midventricular obstruction who received modiifed extended Morrow procedure with extracorporeal circulation in our hospital from 1996-11 to 2015-01. Transthoracic echocardiography was conducted at pre-, post-operation and follow-up period to evaluate the changes of mid-ventricular gradient, subarctic gradient and each heart valve function. Results: The average follow-up time was (25.7 ± 14.9) months, 2 patients lost contact and no death occurred. In rest 32 patients, the mid ventricular gradient decreased from (60.3 ± 29.4) mmHg to (21.0 ± 19.8) mmHg, subaortic valve gradient decreased from (77.9 ± 26.2) mmHg to (11.6 ± 6.5) mmHg, the maximum ventricular septal thickness dropped from (25.2 ± 4.9) mm to (17.9 ± 7.2) mm, left atrial diameter reduced from (41.1 ± 7.8) mm to (37.6 ± 6.4) mm, left ventricular end-diastolic diameter increased from (39.8 ± 5.1) mm to (42.2 ± 4.3) mm, allP<0.05; there were 5 patients without obviously improved mid ventricular gradient because of insufifcient resection of septal myocardium in mid-ventricle. The post-operative NYHA classiifcation was improved,P<0.01, mitral valve regurgitation degree was decreased,P<0.01 and SAM phenomenon was disappeared. Complications included 3 (8.8%) patients of III atrio-ventricular block, 1 (2.9%) patient of re-admission due to poorly healed sternum combining pneumonia Conclusion: Modified extended Morrow procedure may relieve sub aortic valve and mid ventricular obstruction, therefore improve left ventricular diastolic function and prognosis in relevant patients.
