The Curative Effect Of Modified Morrow For The Hypertrophy Obstruction Type Of Cardiomyopathy

OBJECTIVE To evaluate the clinical effects of modified Morrow’s procedure on patients with hyper-trophic obstructive cardiomyopathy.METHODS Reviewed first affiliated hospital of guangxi medical university from January 2010 to January 2015,12 cases of hypertrophic obstructive cardiomyopathy (HOCM), the male 7 cases (58.3%), women in 5 cases (41.7%), age 35±24 years old, some patients failed to ease symptoms after the internal medicine medications, all patients were performed preoperative cardiac computed tomography (CT) and echocardiography, and the.latter in the resting state of left ventricular outflow tract pressure difference> 50 mmHg, all cases improved morrow operation, collect after surgery, postoperative 1 year and 3 years postoperatively review results of echocardiography and electrocardiogram (ecg) data grouped according to the different stage, the sample mean is using t test.R ESULTS Full set of 12 cases without operative death and echocardiographic contrast the indicators are as follows:left ventricular outflow tract (LVOTPG) differential pressure (91.3±28.6) for preoperative mmHg, postoperative (22.4±9.5) mmHg), interventricular septum thickness (preoperative (19.2±4.6) mm, postoperative (12.6±2.8) mm), left atrium diameter (preoperative (36.2±4.2) mm, postoperative (31.8±3.0) mm, postoperative compared with preoperative P< 0.05, the difference was statistically significant, and 1 year after operation, postoperative surgery and postoperative echocardiography of the above 3 years of related index contrast P>0.05, there was no statistically significant difference. And 3 years after the index and left ventricular posterior wall thickness compared with preoperative (P< 0.05, the difference was statistically significant. No serious postoperative complications,6 cases (50%), a new hair arrhythmia, including 1 case appeared I degree atrioventricular block,2 cases with completeness right bundle branch block and 2 cases appeared some sex left bundle branch block,1 cases of incomplete right bundle branch block, no cases of atrial fibrillation.CONCLUSION Modified morrow can effectively reduce the differential pressure of the left ventricular outflow tract, and relieve clinical symptoms, caused by obstruction, and the survival rate is higher.
