Schubert and colleagues developed a novel trileaflet mechanical heart valve prosthesis. They compared this device with a conventional mechanical bileaflet heart valve in vitro, evaluating hemodynamic parameters and thrombogenicity. The trileaflet valve had a larger effective orifice area and smaller pressure gradient than the bileaflet one.

In this prospective single-institution study, functional status trajectory one year after intervention was compared for transcatheter (TAVR) versus surgical aortic valve replacement (SAVR). A moderate/large decline compared to preintervention status occurred in 23% of TAVR patients and 4% of SAVR patients. A frailty index, postoperative delirium, a

Vergnat and colleagues retrospectively evaluated long-term outcomes for neonates who underwent either balloon valvotomy or open valvoplasty between 1989 and 2015 (51 and 52 patients, respectively). Although both methods offer good survival benefits, open valvoplasty was associated with a higher freedom from operation during the follow-up period.

David and colleagues prospectively examined long-term results of the Ross procedure, following a cohort of 212 patients over a median 18.0 years (interquartile range, 14.6-21.2). They report 10.8% cumulative mortality and 16.8% cumulative probability of Ross-related reoperations at 20 years.

The authors demonstrate how to use one homograft root in reoperative infected aortic root/hemiarch reconstruction with the use of a handmade bovine pericardial aortic tube to replace the ascending aorta and unite the divided homograft.
