Long-term survival in coronary artery bypass grafting surgery depending on the second conduit used.

There is still debate whether radial artery (RA) conduits are better grafts then saphenous vein grafts (SVG) as a second conduit in coronary artery bypass grafting (CABG) surgery. Although it has been confirmed that RA grafts have significantly better patency over years, only some observational studies have associated RA use with reduced all-cause mortality. So far, no randomized controlled trial (CRT) has confirmed significantly better survival for RA graft recipients versus SVG recipients.

On-line risk prediction models for acute type A aortic dissection surgery: validation of the German Registry of Acute Aortic Dissection Type A score and the European System for Cardiac Operative Risk Evaluation II.

Objectives: The German Registry of Acute Aortic Dissection Type A (GERAADA) on-line score calculator to predict 30-day mortality in patients undergoing surgery for acute type A aortic dissection (ATAAD) was recently launched. Using the European System for Cardiac Operative Risk Evaluation II (EuroSCORE II), it is also possible to predict operative mortality for the same type of surgery. The goal of our study was to validate the prediction accuracy of these 2 on-line risk prediction models.

Modification of an Old Technique to Correct Kinking of Tubular Graft Interposed to Reconstruct Ascending Aorta.

Cardiac surgeons are occasionally faced with ascending aorta graft kinking following ascending aorta replacement. Although it may be difficult to precisely assess the correct length of the graft during aortic clamping, while performing proximal and distal graft anastomoses on an empty heart, the major reason for graft kinking is its excessive length. Haemolytic anaemia, graft thrombosis or even heart failure have been reported as a consequence of unrecognised and uncorrected kinking of the ascending aortic graft.

Initial experience with the Perceval S sutureless aortic valve.

Introduction: Surgical treatment of the aortic valve represents the gold standard, and thus aortic valve replacement (AVR) is one of the most commonly performed cardiac operations.

Aim: To evaluate the early outcome of aortic valve replacement with the Perceval S sutureless aortic bioprosthesis.

Material And Methods: This was a retrospective analysis of 24 patients (mean age: 71 ±5 years), who underwent aortic valve replacement with a Perceval S valve.
