The occurrence rate of atrial fibrillation (AF) after coronary artery bypass grafting, quoted in the literature, is wide ranging from 5% to over 40%. It is speculated that, off-pump coronary artery bypass grafting (OPCAB) and also minimally invasive cardiac surgery reduces the incidence of postoperative AF due to reduced trauma, ischemia, and inflammation. Current data, however, do not clearly answer the question, whether the incidence of postoperative AF is reduced in using minimally invasive techniques, ideally resulting in the combination of both small access and off-pump surgery. The aim of this study was to evaluate the incidence of postoperative AF in patients undergoing totally endoscopic off-pump coronary artery bypass grafting (TECAB). ⋯ Avoiding cardiopulmonary bypass and minimizing surgical trauma did not reduce the incidence of postoperative AF in this patient collective. It remains an attractive hypothesis that postoperative AF is reduced by off-pump myocardial revascularisation and minimizing surgical trauma but more robust data are required.

Prospective clinical study. ⋯ These findings are important for the operating room personnel, which is exposed daily to radiation intraoperatively, as well as the patients, when using CAS procedures.

Controlled Clinical TrialUltrasound-guided venous access for permanent pacemaker leads.
Existing methods of venous access for permanent pacemaker leads have disadvantages. We documented learning times for ultrasound-guided lead implantation and compared them with cephalic venotomy technique. ⋯ Ultrasound-guided venepuncture for placement of permanent pacing leads is quick to learn and achieves faster lead placement times with shorter and more predictable fluoroscopy time when compared with the cephalic venotomy technique.
