Introduction: This study was planned to see the mid-term clinical and 2-D
echocardiographic outcomes of extensive septal myectomy for hypertrophic obstructive
cardiomyopathy.
Methods: Fifty-one patients of all age groups suffering from HOCM were enrolled in this
study. They were selected on basis of two inclusion criteria are LVOT pressure gradient ≥ 50
mmHg direct by transthoracic echocardiography and second one presence of severe
symptoms despite appropriate medical therapy with Beta-blockers and calcium channel
blockers. A septal myectomy was done. Follow-up: The follow-up period averages 1 year for
HOCM patients. Follow-up data were derived from medical charts and LVOT gradient
information was obtained from the record of transthoracic echocardiography detection at
every outpatient visit.
