Early angiographic evaluation after off-pump coronary artery bypass grafting.
One of the potential drawbacks of off-pump coronary artery bypass is reduced patency compared with conventional coronary artery bypass. This study examined the systematic angiographic evaluation after off-pump coronary artery bypass. ⋯ Smaller coronary diameter would be a predictor of graft failure, whereas percent stenosis diameter greater than 75%, sequential graft, and left main disease would be protective factors for off-pump bypass grafts.

Surgical ventricular reconstruction with endocardectomy along radiofrequency ablation-induced markings.
The objective of this study was to evaluate the efficacy of a novel approach for endocardectomy during coronary artery bypass graft with surgical ventricular restoration in patients with postinfarction left ventricular aneurysm. ⋯ When performed as an integral part of surgical ventricular restoration, endocardectomy was crucial in preventing postoperative ventricular tachycardia. Use of radiofrequency ablation-induced markings allowed clear visualization of the reentry zones for efficient endocardectomy during coronary artery bypass graft with surgical ventricular restoration, resulting in better patient outcomes.

Observational StudyClinical outcomes and fate of the distal aorta following 1-stage repair of extensive chronic thoracic aortic dissection.
To analyze clinical outcomes and distal segmental aortic growth and aortic reoperation rates following 1-stage open repair of extensive chronic aortic dissection that included resection and graft replacement of the aneurysmal descending thoracic aorta. ⋯ Our extended experience with the 1-stage procedure confirms its safety and feasibility for treatment of extensive chronic thoracic aortic dissection. It is associated with a low incidence of reoperation on the contiguous aorta for aneurysmal degeneration. It represents a viable alternative to 2-stage and hybrid procedures that are also used to treat this condition.

Prevention of retrosternal adhesion by novel biocompatible glue derived from food additives.
Postoperative retrosternal adhesion increases the risk of cardiac injury during cardiac reoperation. We created a novel biodegradable glue called "Lydex" that is derived from food additives. The purpose of this study is to evaluate this new biomaterial's biocompatibility and its preventive effect on retrosternal adhesion. ⋯ Our findings indicate that Lydex reduces retrosternal adhesion and attenuates the progression of fibrosis with excellent biocompatibility. Lydex is a next-generation substance for safer cardiac reoperation, with excellent capability for preventing adhesion, biocompatible and biodegradable properties, and lower potential for viral infections related to human plasma or other animal-derived products.
