Impact of the maze procedure and postoperative atrial fibrillation on progression of functional tricuspid regurgitation in patients undergoing degenerative mitral repair.
The aim of this study is to investigate the factors contributing to the progression of functional tricuspid regurgitation (TR) after mitral repair for degenerative mitral regurgitation (MR) in relation to pre and postoperative atrial fibrillation (AF) and performance of the maze procedure. ⋯ Preoperative AF without the maze procedure and postoperative AF can contribute to the development of moderate or greater functional TR after mitral repair for degenerative MR.

Impact of preoperative atrial fibrillation on mortality and cardiovascular outcomes of mechanical mitral valve replacement for rheumatic mitral valve disease.
The prognostic significance of preoperative atrial fibrillation on mitral valve replacement remains unclear. The aim of this study was to explore the effects of the presence of preoperative atrial fibrillation on mortality and cardiovascular outcomes of mitral valve replacement for rheumatic valve disease. ⋯ Preoperative atrial fibrillation is a risk factor for long-term mortality, thromboembolism complications and tricuspid regurgitation, and it also has an adverse effect on the degree of improvement when considering left ventricular function.

First clinical results with the new sinus prosthesis used for valve-sparing aortic root replacement.
Sinuses of Valsalva are important in assuring the physiological function of the aortic valve. This study evaluates short-term clinical results of the reimplantation technique for aortic valve-sparing root replacement using a new prosthesis with three separate sinuses of Valsalva (sinus prosthesis). ⋯ The new sinus prosthesis provides near normal root geometry and hemodynamics in valve-sparing aortic root replacement using the reimplantation technique, applicable for tricuspid and also bicuspid aortic valves.

Early and late prognostic implications of coronary artery bypass timing after myocardial infarction.
The optimal timing of coronary artery bypass grafting (CABG) after myocardial infarction (MI) is still controversial. With advances in perioperative care and myocardial protection, CABG is not infrequently undertaken sooner. Although CABG soon after MI is associated with high morbidity and mortality, the impact of CABG timing on late survival is not clear. ⋯ Early and late mortality risk for CABG declines with increasing interval from MI for reasons indirectly linked to the timing of surgery. Our findings emphasize the importance of preoperative organ system optimization and consistent left internal mammary artery use, regardless of the proximity of surgery to MI or the exigency of surgery.
