Objective: To compare the early clinical effect of septal myectomy and percutaneous transluminal septal myocardial ablation (PTMSA) on the left ventricular outflow obstruction and the rate of complication in patients with hypertrophic obstructive cardiomyopathy (HOCM). Methods: A total of 204 patients with HOCM who received septal reduction treatment were recruited. These patients were divided into two groups, surgery group (n=135) (65 patients with modified Morrow procedure, 70 patients with non-Morrow myomectomy) and PTMSA group (n=69). The baseline characteristics, disease status, other history of surgery and echocardiography parameters before and after septal reduction were collected, as well as the complication within 1 week after operation. Results: The mean age in surgery group was (46±14) years old, with 76 males (56.3%); mean age was (47±11) years old and with 51 males (73.9%) in PTMSA group. There was no significant difference in age, gender, the time of symptom and diagnosis, syncope, family history and atrial fibrillation between the two groups (all P>0.05). The proportion of mitral valve prolapse in the surgery group was higher than that in PTMSA group (75.8% vs 44.2%, P<0.05). Baseline left ventricular outflow tract (LVOT) gradient was comparable (82.7 mmHg in surgery group vs 77.7 mmHg in PTMSA group, P>0.05). The mean resting LVOT gradient after septal reduction therapy was lower (16.55 mmHg in surgery group, 26.68mmHg in PTMSA group) than that before operation, with lower gradient in surgery group (P<0.05). Compared with PTMSA group, the duration of hospitalization was longer in surgery group (P<0.05). There was similar rate of operation related complications in the two groups. Conclusions: Both septal reduction therapies can improve the LVOT obstruction, more significant in surgery group, but with longer hospital stay. The rate of operation related complication is similar in both groups.
