Comparative Study Observational StudyLate outcomes comparison of nonelderly patients with stented bioprosthetic and mechanical valves in the aortic position: a propensity-matched analysis.
Our study compares late mortality and valve-related morbidities between nonelderly patients (aged <65 years) undergoing stented bioprosthetic or mechanical valve replacement in the aortic position. ⋯ In patients aged <65 years, despite an increase in the rate of reoperation with stented bioprosthetic valves and an increase in major bleeding events with mechanical valves, there is no significant difference in mortality at late follow-up.

Analysis of risk factors for recurrence after video-assisted pulmonary vein isolation of lone atrial fibrillation--results of 5 years of follow-up.
The purpose of the present study was to assess the efficacy of the long-term results after video-assisted pulmonary vein isolation and left atrial appendage excision for lone atrial fibrillation (AF) and to determine the most significant risk factors for the long-term results. ⋯ Patients with lone AF with a large preoperative left atrial diameter and long AF duration will not be suitable for video-assisted pulmonary vein isolation alone and might need to undergo ablation of the lesions.

Comparative StudyPreliminary experience with porcine intestinal submucosa (CorMatrix) for valve reconstruction in congenital heart disease: histologic evaluation of explanted valves.
We compared the histologic findings in explanted CorMatrix (9 patients) and autologous pericardium (9 patients) used for valvuloplasty of the aortic (7 patients) and/or mitral (11 patients) valve in patients with congenital heart defects. ⋯ Although CorMatrix used for valve repair induced an intense inflammatory response, little or no remodeling to form tissue resembling a 3-layered native valve was seen at ≤9 months after implantation.

Hybrid approach for transcatheter paravalvular leak closure of mitral prosthesis in high-risk patients through transapical access.
To report "hybrid" procedure feasibility and the clinical success of transcatheter paravalvular leak closure through apical access. ⋯ A "hybrid approach" for transcatheter paravalvular leak closure of mitral prosthesis from the apical route is effective in reducing the regurgitation grade and improving functional capacity in high-risk patients. Complete closure of the defect was maintained at follow-up in most patients.

Five-year real world outcomes of GeoForm ring implantation in patients with ischemic mitral regurgitation.
Reductive ring annuloplasty represents the current standard surgical therapy for ischemic mitral regurgitation (IMR); however, the clinical results have been suboptimal. Etiology-specific prostheses such as the GeoForm annuloplasty ring have been designed to better address the annular and subvalvular perturbations associated with IMR. However, clinical experience is limited, and mid-term results are lacking. ⋯ Implantation of the GeoForm ring offers very good control of IMR, with low rate of recurrent IMR at mid-term follow-up. The use of this prosthesis was associated with good perioperative mortality, mid-term survival, and quality of life.
