Abstract：Objective To evaluate the clinical effects of simultaneous surgical myectomy septal myectomy combined with artial fibrillation treatment in patients with hypertrophic obstructive cardiomyopathy(HOCM)complicated with atrial fibril-lation.Methods The clinical data of patients with HOCM complicated with atrial fibrillation and treated with surgical myectomy in the department of cardiac surgery,Beijing Anzhen Hospital from January 2011 to December 2021 were retrospectively ana-lyzed.The combined radiofrequency ablation group(SG,n=44)and the control group(NG,n=41)were compared between the two groups for surgery and postoperative recovery.Results The SG group had a longer intraoperative aortic occlusion time(122.3±28.5 min vs 109.7±26.2 min).There was no significant difference in mortality between the two groups(P>0.05),and the incidence of postoperative arrhythmia in the SG group was lower(52.3%vs 73.1%P=0.047),but the intensive care unit stay was longer(47.5±23.7h vs 37.8±20.5h,P=0.045).At 3 months,6 months,and 12 months after discharge,the proportion of mainte-nance of sinus rhythm in the SG group was 90.9%,86.4%,and 81.8%,respectively.Conclusion Concomitant ablation of atrial fibrillation during surgical myectomy in patients with hypertrophic obstructive cardiomyopathy complicated with atrial fibrilla-tion is a safe and effective procedure.Its recovery and the maintenance of sinus rhythm are favorable.However,the intensive care unit stay was longer.
