Transcatheter aortic valve implantation (TAVI) for failing aortic root and valve homografts has been described primarily via a transapical approach. We report the successful treatment of two patients with failing homografts by transfemoral (TF) TAVI. In both cases, TF TAVI was accomplished without technical difficulty and with good clinical outcomes.

Percutaneous cannulation allows a prompt approach for establishing veno-arterial extracorporeal membrane oxygenation in acute cardiopulmonary failure. Access to an artery or a vein can sometimes be difficult with severe complications also with percutaneous approach. To reduce morbidity, we describe our technique of a real-time ultrasound cannulation of the femoral vessels.

The use of platelet function testing has been advocated to individualize the time needed between discontinuation of P2Y12 inhibitors and coronary artery bypass grafting (CABG). However, the use of specific point-of-care assays to predict bleeding risk in patients on P2Y12 inhibitors prior to CABG has not been fully validated. ⋯ In patients on P2Y12 inhibitors undergoing CABG surgery, discontinuation of P2Y12 inhibitors three days prior to surgery rather than VerifyNow PRU values predicts postoperative bleeding and the need for platelet transfusions. Sole reliance on platelet function testing to determine the timing of surgery for patients on P2Y12 inhibitors should therefore be done with caution.

The aim of this study is to review the strategy of performing aortic valve replacement (AVR) by using the St. Jude Medical (SJM) Regent valve with a continuous suture technique in patients with a small aortic root. ⋯ Replacement of SJM Regent valve with a continuous suture technique maybe a good option to prevent PPM in the aortic position.

Vascular laceration is a rare but potentially fatal complication with excimer laser-assisted pacemaker or implantable cardioverter-defibrillator lead extraction. We report our experience on management of vascular laceration during laser-assisted lead extraction. ⋯ Cardiopulmonary bypass standby is helpful when performing laser-assisted lead extraction to treat potentially fatal vascular laceration. Dual-coil lead is an independent risk factor to predict intraoperative vascular laceration.
