AusSCORE II in predicting 30-day mortality after isolated coronary artery bypass grafting in Australia and New Zealand.
To update the Australian System for Cardiac Operative Risk Evaluation (AusSCORE) model for operative estimation of 30-day mortality risk after isolated coronary artery bypass grafting in the Australian population. ⋯ The AusSCORE II model provides improved prediction of 30-day mortality and successfully stratifies patient risk. The model will be useful to improve the preoperative consultation regarding risk stratification in terms of 30-day mortality.

Effect of false lumen partial thrombosis on repaired acute type A aortic dissection.
Studies on the partial thrombosis of a false lumen after repairing a type A acute aortic dissection (TAAAD) have reported conflicting results. We investigated the effects of a partially thrombosed false lumen on the segmental growth rates, distal aortic reoperations, and long-term survival. ⋯ Partial thrombosis at each segment of a residual false lumen after TAAAD repair correlated with a faster regional aortic growth rate and predicted a greater reoperation rate but did not affect long-term overall survival.

Impact of tricuspid regurgitation after redo valvular surgery on survival in patients with previous mitral valve replacement.
The impact on survival of tricuspid regurgitation (TR) after redo valvular surgery in patients with previous mitral valve replacement (MVR) is unclear. ⋯ Survival in patients with TR of 2+ or higher after redo valvular surgery was poor. The results of this study suggest that it is important to maintain a postoperative TR less than 2+ to improve long-term survival.

Observational StudyLong-term outcomes of coronary artery bypass grafting patients supported preoperatively with an intra-aortic balloon pump.
Most studies describing the outcome of coronary artery bypass grafting patients supported preoperatively with an intra-aortic balloon pump (IABP) have reported early results. The purpose of our study was to evaluate the early and long-term results. ⋯ In patients supported preoperatively with an IABP, better early and long-term results were strongly related to younger age, a shorter CPB time, and a greater number of bypass grafts. Avoiding the use of CPB (off pump) in these emergency cases is not recommended.

Toward individualized management of the ascending aorta in bicuspid aortic valve surgery: the role of valve phenotype in 1362 patients.
Decision making regarding the management of the ascending aorta (AA) in patients with a bicuspid aortic valve (BAV) undergoing valve surgery has hardly been individualized and remains controversial. We analyzed our individualized, multifactorial approach, focusing on the BAV phenotype. ⋯ The individualized, multifactorial management of AA in patients with BAV during aortic valve surgery leads to excellent results. The threshold AA diameter for intervention (AoP or AAR) varied from 34 to 51 mm (mean, 43.9). BAV type 2/unicuspid and BAV type 1 LR with regurgitation emerged as determinants for more liberal AAR in our practice. Longer term follow-up is necessary to confirm our conclusions.
