Twenty-two patients with rheumatic mitral valve disease and chronic atrial fibrillation with fast, irregular ventricular response were divided into two groups. In the first group ( n = 12), mitral valve replacement was combined with sinus node-AV node isolation (\u2018corridor\u2019); in the second, control group ( n = 10), mitral valve replacement was performed through the left atriotomy. The effectiveness of the \u2018corridor\u2019 procedure on heart rhythm was analysed by: (i) 24-h Holter monitoring performed before and during 72 h after surgery, at hospital discharge, and 2 months later; and (ii) postoperative electrophysiological studies using temporary epicardial wires on each isolated atrial compartment. Immediately after surgery and in the following 2 months, heart rate variability analysis showed significantly lower hourly ventricular rates and rate variations in the \u2018corridor\u2019 group compared with those of the control group ( P &lt; 0.01). A significant difference was also found when comparing postoperative to preoperative findings in the corridor group ( P &lt; 0.05). In the control group, however, no significant differences ( P &gt; 0.05) were found concerning pre- and postoperative ventricular rate variations. At hospital discharge, nine of 12 patients with \u2018corridor\u2019 procedure were in sinus rhythm. Control patients remained in atrial fibrillation with irregular ventricular rate. The \u2018corridor\u2019 procedure, when added to mitral valve replacement, prolonged surgery, but led to restoration and long-term maintenance of sinus rhythm in 75% of patients with chronic atrial fibrillation and rheumatic mitral valve disease. <\/jats:p>","DOI":"10.1177\/096721099700500312","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T18:33:09Z","timestamp":1727202789000},"page":"320-327","source":"Crossref","is-referenced-by-count":1,"title":["Corridor Procedure \u2014 Surgical Option for Treatment of Chronic Atrial Fibrillation in Patients Undergoing Mitral Valve Replacement"],"prefix":"10.1177","volume":"5","author":[{"given":"D.
