Surgical Results and Outcomes After Reimplantation for the Management of Anomalous Aortic Origin of the Right Coronary Artery.
Anomalous aortic origin of the right coronary artery (AAORCA) has been reported to cause myocardial ischemia, leading to angina, dyspnea, and decreased exercise tolerance. Reimplantation is a repair technique devised to exclude the abnormal intramural portion of the anomalous artery and avoid the known late attrition of saphenous vein grafts. Our study aims to evaluate the medium-term clinical outcomes with this technique. ⋯ To the best of our knowledge, this is the largest reported series of anomalous RCA managed by surgical reimplantation. Our results suggest that this technique is safe and has excellent medium to long-term results regarding symptom-free survival.

The stentless Freedom Solo aortic bioprosthesis is implanted supraannularly using one running suture line in the sinuses of Valsalva. We report our 9-year experience with this bioprosthesis. ⋯ Aortic valve replacement with the Freedom Solo is safe and has a low rate of permanent pacemaker implantations and prosthesis-patient mismatch. Survival is comparable to that with other aortic bioprostheses, and structural valve deterioration and aortic valve reoperation are infrequent during midterm follow-up. Hemodynamic performance is excellent, with low valvular gradients that remain stable during follow-up.

Although not currently approved for postoperative cardiac surgical bleeding, recombinant activated factor VII (rFVIIa) has been used for this purpose. This study sought to analyze outcomes in patients who had cardiac surgical bleeding and received low-dose and early administration of rFVIIa versus outcomes in patients who had cardiac surgical bleeding and did not receive rFVIIa. ⋯ Low-dose and early administration of rFVIIa (median total dose 12 mcg/kg) for cardiac surgical bleeding shows potential in achieving hemostasis without increased risk of thromboembolism or acute kidney injury.
