Clinical TrialInitial experience with intraventricular repair using CorMatrix extracellular matrix.
Pericardial patches for intraventricular repair are limited by progressive calcification, thickening, and retraction. The aim of this study was to evaluate the safety of CorMatrix extracellular matrix (ECM) for intraventricular repair of mechanical complications of myocardial infarction (MI). ⋯ In our series, CorMatrix ECM was a safe alternative for ventricular patch repair of mechanical complications after MI in the short-term. This series supports the continued study of the efficacy and the regenerative potential of this novel material for cardiac repair.

Multicenter Study Comparative StudyTwo alternative sutureless strategies for aortic valve replacement: a two-center experience.
Important comorbid conditions in patients referred for aortic valve replacement (AVR) require less invasive strategies. We describe our initial experience with the Perceval S (Sorin Group, Saluggia, Italy) and 3f Enable (Medtronic, Minneapolis, MN USA) sutureless aortic bioprostheses. ⋯ Aortic valve replacement with sutureless aortic bioprosthesis is feasible, also with a minimally invasive approach. The Perceval S showed lower operative times and moderate paravalvular leaks and lower mean transvalvular gradients than did the 3f Enable, related to the larger diameter of the Perceval S implanted. Both prostheses showed an excellent hemodynamic performance. This new technology needs long-term follow-up.

Comparative StudyOutcomes and predictors of mortality and stroke after on-pump and off-pump coronary artery bypass surgery in octogenarians.
Octogenarians, as the fastest growing stratum of the population and with the highest prevalence of coronary artery disease, are being increasingly referred for coronary artery bypass grafting (CABG). The general perception is that the presence of comorbidities and the propensity for neurological injury expose them to a higher risk for mortality and morbidity after conventional on-pump CABG, and therefore, off-pump CABG should be preferentially offered to octogenarians to improve outcomes. This study evaluates the in-hospital outcomes and predictors of mortality and stroke in octogenarians undergoing on- and off-pump CABG at our institution. ⋯ Both on-pump and off-pump CABG are reasonable revascularization strategies in octogenarians. Careful patient selection and individualized treatment decisions can minimize postoperative mortality and morbidity in octogenarians undergoing on- and off-pump CABG.

Comparative StudyRight superior mediastinal lymph node dissection in thoracoscopic surgery using a bipolar sealing device.
This study investigated the use of a new bipolar sealing device (BSD) in right superior mediastinal lymph node dissection during thoracoscopic surgery. ⋯ Our method is safe and in no way inferior to the conventional procedure. The tendency of the learning curve suggests that a significantly shorter duration of lymph node dissection is possible using this method.
