OBJECTIVES: To assess the effects of intraoperative left @entity955 on rhythm and @entity67 . DESIGN: Thirty five @entity1 with @entity453 and documented @entity955 underwent coronary artery bypass surgery and concomitant cryoablation. An age and gender matched control group of 35 @entity1 with @entity955 underwent bypass surgery alone. Echocardiography was performed 9 ? 32 days before and 22 ? 6 months after surgery. RESULTS: The proportion of @entity1 in sinus rhythm at follow-up was 63% and 34% (p = 0.04) in the cryoablation and control groups, respectively. In @entity1 with sinus rhythm both before surgery and at follow-up, the left atrial area increased (p = 0.002) and the mitral annular excursion during atrial contraction decreased (p = 0.01) after cryoablation. The mitral flow velocity during atrial systole decreased after cryoablation (p = 0.002). The LV diameter increased (p = 0.03) and the left ventricular ejection fraction (LVEF) decreased (p = 0.03) in cryoablated but not in control @entity1 . Continued deterioration was seen in @entity1 with @entity955 both pre- and postoperatively. CONCLUSIONS: At long-term follow-up, a significantly higher proportion of @entity1 was in sinus rhythm in the cryoablation than in the control group. The @entity67 had decreased at follow-up two years after surgery. This decrease was small and occurred within or close to the reference values in @entity1 with sinus rhythm at follow-up, while @entity1 remaining in @entity955 showed a significant continued deterioration. Some subgroups were small, and the findings, although statistically significant, should be interpreted with caution.
