The extracellular matrix patch implanted in the right ventricle evaluated with cardiovascular magnetic resonance protocol to assess regional physio-mechanical properties.
An extracellular matrix patch was implanted in the porcine right ventricle for in situ myocardial regeneration. A newly developed cardiovascular magnetic resonance protocol was utilized to investigate the regional physio-mechanical function of the patch. ⋯ With the cardiovascular magnetic resonance protocol, we successfully confirmed early signs of functional myocardial regeneration in implanted extracellular matrix patches. This approach is promising in assessing in situ regional physio-mechanical properties and degree of regeneration of implanted tissue-engineered materials.

Comparative StudyIs the Ross procedure a riskier operation? Perioperative outcome comparison with mechanical aortic valve replacement in a propensity-matched cohort.
The aim of this study was to compare perioperative outcomes in young adults following isolated Ross procedure versus mechanical aortic valve replacement (AVR) in a high-volume centre. ⋯ There are no differences in mortality or major perioperative outcomes in adults undergoing an isolated Ross procedure or mechanical AVR.

Comparative Study Observational StudyTranscatheter valve-in-valve implantation versus redo surgical aortic valve replacement in patients with failed aortic bioprostheses.
Transcatheter aortic valve-in-valve implantation (ViV) is a new treatment for failing bioprostheses (BP) in patients with high surgical risk. However, comparative data, using standard repeat surgical aortic valve replacement (redo-SAVR), are scarce. We compared outcomes after ViV with those after conventional redo-SAVR in two European centres with established interventional programmes. ⋯ Despite a higher risk profile in the ViV group, early mortality rates were not different compared with those of surgery. Although ViV resulted in elevated transvalvular gradients and therefore a lower rate of device success, mortality rates were similar to those with redo-SAVR. At present, both techniques serve as complementary approaches, and allow individualized patient care with excellent outcomes.
