[Results of surgical treatment in supraventricular tachycardias].
From May 1989 to May 1992, 44 patients (mean age 41 years, range 15-66) underwent surgery for supraventricular tachycardias: in 35 patients with atrioventricular reentrant tachycardia or atrial fibrillation associated with accessory pathway and refractory to medical treatment, the epicardial approach was used; in 8 with atrioventricular nodal reentrant tachycardia, a perinodal cryosurgery of the atrioventricular node was used, and in 1 patient with atrial flutter a cryosurgical ablation around the orifice of the coronary sinus and surrounding tissues was performed. All 38 accessory pathways were successfully ablated in 35 patients and no recurrences of delta wave or tachycardia were observed during a mean follow-up of 17 +/- 10 months. Atrial perforation during surgery and pericarditis were the only complications observed. All 8 patients with atrioventricular nodal reentrant tachycardia were successfully treated: in 2 patients dual pathways persisted after surgery but tachycardia was no longer inducible. No recurrences were observed during a mean follow-up of 15 +/- 4 months. Since surgery (15 months), the patient with atrial flutter has been free of recurrent episodes of atrial flutter. In conclusion, surgical treatment of supraventricular tachycardias is highly successful, with no mortality and very low morbidity. Should transcatheter ablation fail, surgery should be the treatment of choice in patients with frequent and symptomatic supraventricular tachycardias.
