A proposed index of myocardial staining for vein of Marshall ethanol infusion: an Italian single-center experience.

Background: Mitral isthmus (MI) conduction block is a fundamental step in anatomical approach treatment for persistent atrial fibrillation (PeAF). However, MI block is hardly achievable with endocardial ablation only. Retrograde ethanol infusion (EI) into the vein of Marshall (VOM) facilitates MI block.

Echocardiographic Biventricular Coupling Index to Predict Precapillary Pulmonary Hypertension.

Background: Pulmonary hypertension (PH) is a frequent and detrimental condition. Right heart catheterization (RHC) is the gold standard to identify PH subtype (precapillary from postcapillary PH) and is key for treatment allocation. In this study, the novel echocardiographic biventricular coupling index (BCI), based on the ratio between right ventricular stroke work index and left ventricular E/E' ratio, was tested for the discrimination of PH subtype using RHC as the comparator.

A novel echocardiographic method for estimation of pulmonary artery wedge pressure and pulmonary vascular resistance.

Aims: This study aimed to evaluate a novel echocardiographic algorithm for quantitative estimation of pulmonary artery wedge pressure (PAWP) and pulmonary vascular resistance (PVR) in patients with heart failure and pulmonary hypertension (PH) scheduled to right heart catheterization (RHC).

Methods And Results: In this monocentric study, 795 consecutive patients (427 men; age 68.4 ± 12.

Catheter cryoablation of ventricular ectopy originating from his region.

Careful mapping, early detection of AV conduction damage and cryothermal energy availability are essential in dealing with ablation procedures at the parahisian region.
