Clinical Trial
Minimally invasive hybrid ablation procedure for the treatment of persistent atrial fibrillation: one year results.
The concept of a hybrid approach, combining the most effective techniques of surgical and endocardial catheter ablation has resulted in the creation of the convergent ablation procedure. This novel, pericardioscopic, hybrid approach can be an effective option for highly symptomatic patients with persistent atrial fibrillation (PSAF) and longstanding persistent atrial fibrillation (LSPAF) for whom standalone surgical or endocardial ablation procedures offer sometimes unsatisfactory outcomes. ⋯ Hybrid, epicardial and endocardial, radiofrequency ablation is feasible and safe, effectively restoring sinus rhythm in the vast majority of patients with PSAF and LSPAF.

To evaluate long-term outcomes of surgical aortic valve replacement (AVR) due to significant aortic stenosis (AS) and assess changes in factors affecting survival during a 10-year period in patients referred for surgery from a single centre. ⋯ Long-term surgical outcomes in patients with significant AS are very good, with better survival in women compared to men, although these differences attenuated after 3 years. Factors affecting 10-year survival are different in women and men: a significant effect in women was noted only for age and preoperative NYHA class, while in men for age, NYHA class, hypertension, reduced LVEF, and the presence of significant coronary artery stenoses. During 10-year follow-up, longitudinal changes can be noted in factors affecting survival after AVR.

Postoperative complications are integral to cardiac surgery. The most serious ones are stroke, which develops in about 7.5% of the patients, and postoperative encephalopathy, which affects 10-30% of the patients. According to bibliographical data, the number of complications is increasing. ⋯ In patients undergoing heart surgery, the independent risk factors of neurological complications in the first 30 days include: long duration of ventilation, a history of stroke with paresis, AF, haemodilution manifested by an HCT of <28% and long duration of aortic cross-clamping. Neurological complications are associated with high postoperative mortality.
