Encircling isolation of pulmonary vein orifice for elimination of persistent atrial fibrillation associated with mitral valve disease.
The authors treated a 70-year-old woman with persistent atrial fibrillation associated with mitral valve stenosis. Restoration of sinus rhythm was achieved with encircling isolation of pulmonary vein orifices concomitant with mitral valve replacement. A vertical incision in the right side of left atrium was extended to the margin of the upper and lower left pulmonary vein orifices. Supplemental cryo-coagulation was applied to the remnant of the circular incision, avoiding the entire encircling incision. Consequently, all pulmonary veins were electrically isolated. Encircling pulmonary vein orifice isolation is less invasive than the MAZE procedure because of reductions in surgical time and cardiopulmonary bypass time, minimization of atrial incisions, and prevention of injury to the coronary artery. It is thus an effective option for selected patients with atrial fibrillation.
