Achieving metrics during beating-heart ex-maze procedures improves outcomes.
Current surgical treatments for atrial fibrillation (AF) lack intraoperative metrics that predict long-term outcomes. The extracardiac maze (Ex-Maze) procedure is a beating-heart maze procedure that causes spontaneous conversion to sinus rhythm (SR) during lesion creation. Spontaneous conversion and confirmation of pulmonary vein exit block are 2 important predictors of long-term freedom from AF. ⋯ Recent advances in techniques and technologies permit the creation of a comprehensive biatrial lesion pattern on the epicardium of a beating heart. Observation of spontaneous conversion and confirmation of pulmonary vein exit block are important metrics that predict improved long-term outcomes.

Restrictive mitral valve annuloplasty for chronic ischemic mitral regurgitation: a 5-year clinical experience with the physio ring.
This study investigated the results of restrictive mitral annuloplasty with the semirigid Carpentier-Edwards Physio ring in patients with moderately severe to severe chronic ischemic mitral regurgitation (IMR) and advanced ischemic cardiomyopathy (ICM). ⋯ Restrictive mitral valve annuloplasty using the semirigid Physio ring corrected chronic IMR in ICM patients with very low mortality and improved contractility. Surgery also prevented recurrence of significant IMR in parallel with the phenomenon of postoperative continuous reverse myocardial remodeling.

Comparative StudyPreoperative prophylaxis can decrease rates of atrial fibrillation in open heart surgery: a retrospective study.
We investigated the effects of preoperative administration of beta-blockers on the incidence of atrial fibrillation (AF) after cardiothoracic surgery and the resulting morbidity and mortality. ⋯ Postoperative AF increases the rates of morbidity and mortality and the length of hospital stay after CABG. The prophylactic use of beta-blockers decreases the rate of postoperative AF and thus AF-related complications.

Reconstruction of chronic aseptic sternal pseudoarthrosis after median sternotomy: initial experience with the Ley prosthesis.
It has previously been reported that the Ley prosthesis, a 0.5-mm-thick titanium alloy plate designed for reconstruction and stabilization of the unstable sternotomy, leads to shorter hospital stay and reduces the need for further surgical procedures in patients with postoperative mediastinitis after open heart surgery. We report our initial experience with the Ley prosthesis in patients with chronic aseptic sternotomy dehiscence. The study included 6 male patients (age 42-80 years) with opiate-derivate-dependent intractable pain and significantly reduced quality of life caused by noninfected sternal pseudoarthrosis and unstable sternotomy with large sternal bone tissue deficit. ⋯ One patient who received a bone transplant developed wound infection, and the prosthesis was removed 5 weeks after implantation. At 6-month follow-up all sternotomies were found stable, and patients reported that pain had decreased and quality of life was significantly improved. Our results demonstrate that the Ley prosthesis can be safely and efficiently used for the reconstruction and stabilization of the sternum in patients with intractable pain caused by noninfected postoperative sternal dehiscence and large sternal bone tissue deficit.
