Right heart catheterization (RHC) provides critical hemodynamic insights by measuring atrial, ventricular, and pulmonary artery pressures, as well as cardiac output (CO). Although the use of RHC has decreased, its application has been linked to improved outcomes. Advanced hemodynamic markers such as cardiac power output (CPO), aortic pulsatility index (API), pulmonary artery pulsatility index (PAPi), right atrial pressure to pulmonary capillary wedge pressure ratio (RAP/PCWP) and right ventricular stroke work index (RVSWI) have been introduced to enhance risk stratification in cardiogenic shock (CS) and end-stage heart failure (HF) patients.

AC is significantly influenced by arterial wall structure and vasomotion, and it markedly influences cardiac load. A new method, based on a two-element Windkessel model, has been recently proposed for estimating AC as the ratio of the time constant T of the diastolic blood pressure decay and peripheral vascular resistance derived from clinically available stroke volume measurements and selected peripheral blood pressure parameters which are less prone to peripheral distortions.

Transcatheter aortic valve repair (TAVR) presents a minimally invasive alternative to traditional surgical valve replacement, albeit not without its own set of complications. A rare complication is the infolding of the self-expanding valve, which can precipitate cardiac arrest. The estimated incidence rate of this complication stands at 1.

Background: Ventricular fibrillation (VF) is a vicious arrhythmia usually generated after removal of the aortic cross-clamp (ACC) in patients undergoing open-heart surgery, which could damage cardiomyocytes, especially in patients with left ventricular hypertrophy (LVH). Amiodarone has the prominent properties of converting VF and restoring sinus rhythm. However, few studies concentrated on the effect of amiodarone before ACC release on reducing VF in patients with LVH.

Transcatheter aortic valve replacement (TAVR) has become a viable treatment option for patients with severe aortic stenosis among all risk subsets. As TAVR use becomes more prevalent and patients live longer with their transcatheter valve, an increasing number of these patients can be expected to present with ACS. Overall, there is a paucity of high-quality data detailing incidence, pathophysiology, and management of ACS in this subset.
