Dr. Asai and colleagues from Japan report on their midterm results using the "butterfly" technique of leaflet resection for posterior leaflet prolapse. In this procedure, the shape of the resected specimen of prolapsed leaflet resembles the shape of a butterfly as opposed to the conventional quadrangular shape.

The authors describe a "huge" increase in ECMO usage for pulmonay failure with a trend, though not statistically significant, towards improved outcomes.

This RCT compared daily 200mg or 300mg of FXI-ASO (an antisense oligonucleotide that reduces levels of factor XI) to daily 40mg of enoxaparin in pts undergoing knee replacement surgery. The end point was thromboembolism. FXI-ASO significantly reduced factor XI levels in a dose-response manner. FXI-ASO 200 mg was equivalent to enoxaparin in frequen

This multicenter study analyzes the utility of a "Top Gun" competition in promoting simulator use and improving technical skills among 1st-year CT Surgery residents. A coronary anastomosis simulation module was sent to most 1st-year residents in the U.S. Fifteen residents submitted baseline and final videos for evaluation.

Results from the European REdo Cardiac Operation Research Database (RECORD) indicate that outcome of redo aortic valve replacement is influenced by baseline risk factors and perioperative complications. Hospital mortality was seen in 5.1% of 711 evaluated cases.

The CCF group conducted a study of their phlebotomy practices during a 6-month period in 2012. Phlebotomy volumes on each patient were estimated and calculated. Surprisingly, the group found that, on average, cardiac surgery patients lose ~10% of their blood volume due to postoperative phlebotomy alone.

The FDA recently approved the fourth new oral anticoagulant, Savaysa for use in non-valvular afib, DVT, and PE. It is another factor Xa inhibitor. Use in non-valvular afib requires renal function assessment prior to prescribing, as the drug is renally excreted. Paradoxically, efficacy may be reduced in patients with better-than-normal renal functi

Outcomes of surgical AVR were summarized from the STS Cardiac Surgery Database 2002-2010 to establish contemporary data for different surgical risk groups (low <4% risk, intermediate 4%-8% risk, high >8% risk). 80% were low risk, 6% were high risk. Hospital mortality was lower than predicted by STS PROM for all groups (low: 1.4$ vs 1.7%; inte

This study randomized 100 patients with AS to full sternotomy AVR with a conventional prothesis or hemisternotomy with a rapid deployment prosthesis. CPB times were similar, but Ao crossclamp times were 24% shorter in the rapid deployment group. Acute outcomes were similar. The rapid deployment group had a lower transvalvular gradient and a lower
