僧帽弁手術中に心房細動(AF)に対し左房(LA)のみ1~3)に外科的アブレーション(SAB)を9例に施行し(LA-SAB),最長15年の経過観察をしえたので報告する.
Concomitant left atrial (LA)-only surgical ablation (SAB) of atrial fibrillation (AF) with mitral valve procedure was performed in nine cases with radiofrequency ablation devices. LA-SAB includes connected bilateral pulmonary vein isolations, mitral isthmus ablation, and LA appendage ablation and occlusion at its base. There were no such adverse events as 30-day mortality, thromboembolic event, permanent pacemaker implantation, readmission due to heart failure, or cardiac death (follow-up:mean:10±5 years, range:0.75~15 years). Freedom from AF without classⅠ/Ⅲ antiarrhythmic drugs at six months was 77.8%(7 of 9 cases), and sinus rhythm (SR) has been maintained more than 10 years in 4 of those 7 cases. In one of two postoperative AF cases, SR recovery was confirmed four years after surgery, and AF has not been detected for three years. LA-SAB is considered to be safe, effective, and feasible, although further investigation and patient selection are needed.
