OBJECTIVE: Patients with severe tricuspid regurgitation and persistent atrial fibrillation may not be good candidates for maze procedure due to preoperative atrial remodeling and various comorbidities. We attempted to evaluate the rhythm and clinical outcomes of maze procedure in these patients.
METHODS: Patients with severe tricuspid regurgitation and persistent atrial fibrillation who underwent tricuspid valve surgery between January 1994 and December 2017 at a single tertiary center were analyzed. The primary end point was sinus rhythm restoration. The key secondary end point was major adverse cardiovascular and cerebrovascular event rate, which is the composite event of stroke, cardiac death, major bleeding, and readmission for heart failure. Propensity score matching analysis was used.
RESULTS: A total of 388 patients underwent tricuspid valve surgery, and among them 172 patients (44%) underwent concomitant maze procedure. The maze group had sinus rhythm restoration rate of 56% in 9 years. Further, in the matched cohort, the maze group had higher freedom from major adverse cardiovascular and cerebrovascular event rate at 10 years than the nonmaze group (55.6% vs 36.2%; P = .047). Preoperative left atrial diameter (hazard ratio, 1.022; 95% CI, 1.012-1.033; P < .001) and right atrial diameter (hazard ratio, 1.012; 95% CI, 1.003-1.022; P = .013) were independent risk factors for failure of sinus rhythm.
CONCLUSIONS: Maze procedure in severe tricuspid regurgitation and persistent atrial fibrillation had acceptable rates of sinus rhythm restoration and reduced major adverse cardiovascular and cerebrovascular events in the long-term. Careful patient selection considering preoperative atrial diameters is needed to enhance maze success rate and long-term clinical outcomes.
