Pulmonary vein isolation procedure
was performed for atrial fibrillation associated with mitral
valve disease in twelve patients. This simple procedure consisted
of only isolation of the four pulmonary veins. Combined mitral
valve surgery consisted of mitral valve plasty, mitral valve
replacement with or without aortic valve replacement and tricuspid
annuloplasty. Ten patients returned to a sinus rhythm. Two patients
required DDD pacemaker implant for sick sinus syndrome. Left
atrial contraction was detected in eight cases by trans-esophageal
echography. Compared with the maze procedure, this operation
was less invasive and preserved atrial appendage, helping to
maintain normal secretion of atrial natriuretic peptide. This
study suggests that the pulmonary vein isolation procedure may
be an effective and simple maneuver for atrial fibrillation associated
with mitral valvular disease.
