Comparative Study
Effect of coronary artery disease extent on contemporary outcomes of combined aortic valve replacement and coronary artery bypass graft surgery.
Concomitant aortic valve replacement (AVR) and coronary artery bypass graft surgery (CABG) is a common procedure. Whether the extent of coronary artery disease (CAD) influences outcomes of AVR plus CABG is unknown. ⋯ Compared with AVR plus CABG for one- or two-vessel CAD, AVR plus CABG for left main or three or more vessel CAD had higher observed and risk-adjusted rates of postoperative complications but not operative or 1-year mortality.

Disclosure of physician-specific behavior improves blood utilization protocol adherence in cardiac surgery.
Evidence indicates that a transfusion (Tx) trigger hemoglobin (Hgb) value of 8 gm/dL may be safer than a more liberal Tx trigger in cardiac surgery (CS) patients. We hypothesized that weekly physician feedback would improve adherence to such a protocol, but that the public identification of individual physician behavior would have an additive effect. ⋯ Blood transfusion protocol adherence improves when weekly feedback is provided. Identifying individual surgeon behavior improves adherence to a greater degree. Routine presentation of quality metrics with identification of individual physician-specific behavior may be the most effective way to accomplish performance improvement.

Multicenter Study Comparative Study Clinical Trial
Transapical aortic valve replacement for severe aortic stenosis: results from the nonrandomized continued access cohort of the PARTNER trial.
Transapical (TA) aortic valve replacement was an integral part of the Placement of Transcatheter Aortic Valves (PARTNER) trial. Enrollment during the randomized trial included 104 transapical (premarket approval TA [PMA-TA]) and 92 surgical aortic valve replacements (SAVR) within the TA cohort. On completion of the trial, enrollment continued in a nonrandomized continued access (NRCA) program. We compared the outcomes of NRCA-TA procedures with those of PMA-TA and SAVR. ⋯ Among the 975 patients in the NRCA-TA cohort, rates of major outcomes including death and stroke compared favorably with outcomes of PMA-TA and SAVR patients enrolled in the PARTNER trial. This trend toward improved outcomes may be attributed to improved patient selection, individual centers surmounting the procedural learning curve, and refinements in surgical technique.

Comparative Study
Sutureless implantation of the perceval s aortic valve prosthesis through right anterior minithoracotomy.
Many new, less invasive strategies are proposed for aortic valve operation in elderly patients. Rapid deployment sutureless aortic valve prosthesis has been recently introduced. We analyzed our experience with a sutureless valve implanted through a minimally invasive approach. ⋯ A sutureless valve for minimally invasive aortic valve replacement is a feasible, effective, and safe tool. Ultimately amplifying indications for less invasive aortic valve replacement in a high surgical risk subset of patients, it can become a valid alternative for transcatheter aortic valve implantation.
