Randomized Controlled Trial Multicenter Study Comparative StudyCost-effectiveness of ablation surgery in patients with atrial fibrillation undergoing cardiac surgery.
This study was performed to assess the cost-effectiveness of concomitant ablation surgery (AS) compared to regular cardiac surgery in atrial fibrillation (AF) patients over a one-year follow-up. Cost analysis was performed from a societal perspective alongside a prospective, randomised, double-blinded, multicentre trial. One hundred and fifty patients with documented AF were randomly assigned to undergo cardiac surgery with or without AS. ⋯ The incremental cost-effectiveness ratio is €73,359 per QALY. The acceptability curve showed that, even in the case of a maximum threshold value of €80,000 per QALY gained, the probability of AS being more cost-effective than regular cardiac surgery did not reach beyond 50%. Concluding that concomitant AS in AF is not cost-effective after a one-year follow-up compared to regular cardiac surgery.

Multicenter Study Comparative StudyDoes the technique of distal anastomosis influence clinical outcomes in acute type A aortic dissection?
The purpose of this study was to evaluate clinical outcomes of two different surgical techniques for the repair of acute type A dissection: open distal anastomosis under deep hypothermic circulatory arrest (DHCA) compared with distal aortic clamping on hypothermic cardiopulmonary bypass (ACPB). Between January 2000 and July 2008, 82 patients underwent DHCA and 42 had ACPB. Major morbidity, operative mortality and five-year actuarial survival were compared between groups. ⋯ No significant differences in operative mortality, major morbidity and actuarial five-year survival were observed between DHCA and ACPB. There are some practical technical advantages if the distal anastomosis is performed in an open manner. More studies are required to determine the fate of the false lumen between the two techniques.
