Background: (A) Very severe aortic valve stenosis (VSAS; Vmax ≥ 5 m/s, MPG ≥60 mmHg) is a critical condition with unfavorable clinical outcomes. Guidelines regard VSAS as one criterion for considering valve replacement in asymptomatic patients. (B) Guidelines recommend the use of aortic valve calcium (AVC) scoring as a parameter to differentiate between moderate and severe aortic valve stenosis (SAS).

This study investigates the impact of prediabetes on short- and long-term survival outcomes in patients who experienced ST-elevation myocardial infarction (STEMI). In this retrospective, single-center cohort study, we evaluated 725 STEMI patients stratified into non-diabetic, prediabetic, and diabetic groups based on HbA1c levels at presentation.

- A study examined the long-term survival impacts of pre-existing pulmonary hypertension (PH) in patients with severe aortic valve stenosis (AS) undergoing transcatheter aortic valve replacement (TAVR), focusing on gender differences.
- Analysis of 303 TAVR patients revealed that only males with elevated systolic pulmonary artery pressure (sPAP) showed a significant increase in mortality over 5 years, while high sPAP did not affect survival rates in females.
- The findings suggest that male gender is a key risk factor for higher mortality post-TAVR in patients with PH and severe AS, indicating the need for careful consideration when deciding on TAVR for men with these conditions.
Introduction: Up to 50% of patients suffering from acute decompensated heart failure show normal or slightly reduced left ventricular ejection fraction (LVEF). This syndrome, which is known as heart failure with preserved ejection fraction (HFpEF) is associated with increasing age. Epidemiological studies could portrait an increasing importance and an even emerging prevalence in the past decades.

Transcatheter aortic valve implantation (TAVI) is a therapeutic alternative in symptomatic patients at high or prohibitive perioperative risk. Predilatation by balloon aortic valvuloplasty (BAV) under rapid ventricular pacing (RVP) has been a routine part of TAVI.

The aim of this study was to evaluate the in-hospital outcomes of patients receiving heparin or bivalirudin in a real-world setting of PPCI: 7,023 consecutive patients enrolled in the Austrian Acute PCI Registry were included between January 2010 and December 2014. Patients were classified according to the peri-interventional anticoagulation regimen receiving heparin (n = 6430) or bivalirudin (n = 593) with or without GpIIb/IIIa inhibitors (GPIs).
