Observational StudyLong-term results of Freestyle stentless bioprosthesis in the aortic position: a single-center prospective cohort of 500 patients.
Stentless xenograft bioprostheses may be the future valve of choice for aortic valve replacement. The study aim was to investigate the long-term clinical outcome after aortic valve replacement with the Medtronic Freestyle bioprosthesis (Medtronic Inc, Minneapolis, Minn). ⋯ The use of the Freestyle bioprosthesis for aortic valve replacement resulted in good long-term cardiovascular survival and freedom from structural valve deterioration in this cohort regardless of age at implantation.

Comparative StudyEvent recorder monitoring to compare the efficacy of a left versus biatrial lesion set in patients undergoing concomitant surgical ablation for atrial fibrillation.
Various lesion sets and subsequent success rates have been reported in patients receiving concomitant surgical ablation for atrial fibrillation. However, most of these results have been obtained by discontinuous monitoring. We report results using continuous event recorder rhythm monitoring to compare more accurately the efficacy of a left versus biatrial lesion set to treat patients with persistent atrial fibrillation. ⋯ Continuous rhythm monitoring by subcutaneous event recorder implantation was safe and feasible. In patients undergoing biatrial ablation, a statistically significant higher rate of freedom from atrial fibrillation was observed at 12 months follow-up.

Comparative StudyIncidence and outcomes of right-sided endocarditis in patients with congenital heart disease after surgical or transcatheter pulmonary valve implantation.
To evaluate right-sided endocarditis and compare the incidence, clinical presentations, and outcomes in patients with a surgical and percutaneous pulmonary valve. ⋯ There is a higher incidence of endocarditis in patients with PPVI compared with surgical pulmonary valves. Clinical and biological features were comparable in both groups. The role of bovine jugular veins in the development of endocarditis is concerning. However, despite a higher incidence of endocarditis in the PPVI group, the probabilities of survival and event-free survival were similar to the surgical group.
