Background: The evaluation of myocardial ischemia in patients with aortic valve stenosis (AS) with concomitant coronary artery disease (CAD) and possible microvascular dysfunction (MVD) is challenging because fractional flow reserve (FFR) and the resting full-cycle ratio (RFR) have not been validated in this clinical setting.
Objectives: The objectives of this study in patients with AS and CAD were: 1) to describe the relationship between hyperemic and resting indexes; 2) to investigate the acute and long-term effects of aortic valve replacement (AVR) on epicardial indexes and microvascular function; 3) to assess the impact of these changes on clinical decision making; and 4) to determine FFR/RFR ischemia cutoff points in AS.
Methods: In this prospective multicentric study, we performed serial measurements of FFR and RFR and evaluated MVD by means of coronary flow reserve, the index of microvascular resistance, and microvascular resistance reserve in patients with severe AS and intermediate to severe CAD before and 6 months after AVR.

Article Synopsis
- The study aimed to explore differences in characteristics and 2-year outcomes after surgical aortic valve replacement (SAVR) between males and females, using data from two registries involving 933 patients.
- Females had certain clinical differences such as lower body mass index, higher surgical risk scores, and smaller valves compared to males, but these disparities largely disappeared after adjusting for similar baseline characteristics.
- Ultimately, despite a higher initial surgical risk profile, both sexes had comparable outcomes 2 years post-SAVR, indicating no significant differences in overall results based on sex.
Objectives: The potential risk of autograft dilatation and homograft stenosis after the Ross procedure mandates lifelong follow-up. This retrospective cohort study aimed to determine long-term outcome of the Ross procedure, investigating autograft and homograft failure patterns leading to reintervention.
Methods: All adults who underwent the Ross procedure between 1991 and 2018 at the University Hospitals Leuven were included, with follow-up data collected retrospectively.
Background: The aim of this study is to report the preliminary real-word clinical and hemodynamic performance from the MANTRA study in patients undergoing aortic valve replacement with Perceval PLUS sutureless valve.
Methods: MANTRA is an ongoing "umbrella" prospective, multi-center, international post-market study to collect real-life safety and performance data on Corcym devices (Corcym S.r.
Preclinical testing using animal models is indispensable in cardiovascular research. However, the translation to clinical practice of these animal models is questionable since it is not always clear how representative they are. This systematic review intends to summarize the interspecies differences in the coagulation profile of animal models used in cardiovascular research.
