ABSTRACT

Objective: To evaluate surgical treatment of chronic atrial fibrillation with ultrasoundin patients with mitral valve disease, considering preoperative clinicalcharacteristics of patients undergoing surgical procedure and follow-up inthe immediate postoperative period, in hospital and up to 60 months afterdischarge.

Methods: We studied 100 patients with chronic atrial fibrillation and mitral valvedisease who underwent surgical treatment using ultrasound ablation. Patientdata were reviewed by consulting the control reports, including signs andsymptoms, underlying disease, functional class, hospital stay, surgicalprocedure time, ablation time, immediate complications, and complications atdischarged and up to 60 months later. Actuarial curve (Kaplan-Meier) wasused for the study of permanence without recurrence after 12, 24, 36, 48 and60 months.

Results: 86% of the patients had rheumatic mitral valve disease, 14% had degenerationof the mitral valve, 40% had mitral regurgitation, and 36% had mitralstenosis. Main symptoms included palpitations related to tachycardia bychronic atrial fibrillation (70%), congestive heart failure (70%), andprevious episodes of acute pulmonary edema (27%). Early results showed that94% of the patients undergoing ultrasound ablation reversed the rate ofchronic atrial fibrillation, 86% being in sinus rhythm and 8% inatrioventricular block. At hospital discharge, maintenance of sinus rhythmwas observed in 86% of patients and there was recurrence of chronic atrialfibrillation in 8% of patients. At follow-up after 60 months, 83.8% ofpatients maintained the sinus rhythm.

Conclusion: Surgical treatment of chronic atrial fibrillation with ultrasound concomitantwith mitral valve surgery is feasible and satisfactory, with maintenance ofsinus rhythm in most patients (83.8%) after 60 months of follow-up.

f6: Results obtained postoperatively with respect to relapse of chronicatrial fibrillation in patients undergoing US ablation.

Mentions: After hospital discharge, patients were followed-up in outpatient clinics withconduction of CPB, 24-hour Holter, and echocardiogram, initially and at 15, 30, and60 days postoperatively. Clinical follow-up of late postoperative period wasperformed at 12, 24, 36, 48 and 60 months after hospital discharge. Figure 6 shows the results of the relapse in thepostoperative period. Follow-up time ranged from 12 to 60 months. At follow-up after60 months, 83.8% of patients maintained relapse-free sinus rhythm (Figure 7).
