Ischemic mitral regurgitation (IMR) recurrence after combined coronary artery bypass grafting (CABG) and mitral valve repair does occur, with a prevalence of 20% to 30% at the 2- to 4-year follow-up. This single-center study aims to identify the predictors of IMR improvement after surgical revascularization plus mitral valve repair for moderate IMR. ⋯ An LVEDD of less than 65 mm, the use of a rigid complete ring, and combined restrictive annuloplasty and subvalvular and/or leaflet repair are associated with IMR improvement after CABG plus mitral valve repair for the treatment of moderate IMR; IMR improvement 2 years after surgery is associated with improved midterm outcomes.

Meta Analysis Comparative Study
Intraoperative graft flow profiles in coronary artery bypass surgery: A meta-analysis.
Conduits used in coronary artery bypass artery grafting (CABG) have different properties and flow profiles. We compared intraoperative mean graft flow (MGF) between arterial and venous conduits, off-pump CABG (OPCABG) and on-pump CABG (ONCABG) procedures, skeletonized and pedicled internal mammary artery (IMA) grafts, and pulsatility index (PI) between OPCABG and ONCABG, in pairwise meta-analyses. ⋯ Intraoperative flow of venous conduits is higher than that of arterial grafts. Compared to OPCABG surgery, graft flow is higher in ONCABG. In skeletonized and pedicled IMA conduits, no difference in flow profiles was found.

Clostridium septicum aortitis is a lethal infection. C. septicum has a strong association with an underlying malignancy, most commonly in the colon. ⋯ Delay in identification and treatment of C. Septicum is associated with very high mortality rates.

Due to the shortage of donor pool, there has been a need for organs with prolonged cold ischemic time. This study aims to evaluate the short-term results of different cold ischemic times in orthotopic heart transplantation based on a single-center experience in China. ⋯ Cold ischemic time less than 8 hours can be reasonably applied to expand the heart transplantation donor pool. Cold ischemic time greater than 8 hours might result in longer CPB time, CPB-assist time, and higher IABP usage postoperatively. It might also affect the in-hospital and 2-years survival rate.
