A mix of aminophylline and heparin plus nitroglycerin can reduce bradycardia during rotational atherectomy on the right coronary artery and dominant circumflex artery.

Background: Rotational atherectomy (RA) may cause bradyarrhythmias and transitory atrioventricular block when performed in the right coronary artery (RCA) or a dominant circumflex (CX) coronary artery. However, there are no studies of a solution that can prevent coronary flow deterioration and bradycardia complications that may occur during RA. We aimed to create an alternative rota-flush solution to minimize the risk of bradycardia and complete atrioventricular block (AVB) that can occur during RA.

The eft Dstal ransradial ccess site cold give a safe alterate sit for trasradial coronary inervention (The Study).

Transradial Access (TRA) is the suggested method when performing coronary procedures. TRA has several advantages over the transfemoral approach, but also some restrictions. The present study compared the efficacy and safety of the traditional proximal transradial approach (pTRA) with a newer technique known as the distal transradial approach (dTRA) for performing a coronary angiography (CAG) and percutaneous coronary intervention (PCI).

The right ventricle systolic force ratio could predict the severity of the tricuspid regurgitation-RIVIERA ratio.

Purpose: For assessing the severity of tricuspid regurgitation (TR), there is no gold standard. We developed a parameter, the right ventricular systolic force ratio-RIVIERA, using the continious wave Doppler analysis of TR and pulsed-wave analysis of the right ventricle outflow tract. We hypothesized that the RIVIERA would facilitate the ability to identify severe TR in clinical settings.

The simple right ventricle contraction pressure index: A novel method for echocardiographic assessment of right ventricle dysfunction in acute pulmonary embolism.

Purpose: The simple right ventricular contraction pressure index (sRVCPI) is a new echocardiographic variable for estimating the right ventricular systolic function. Our aim was to investigate the association between the sRVCPI, the pulmonary embolism severity index (PESI), and mortality rate in acute pulmonary embolism (APE).

Methods: We included in this study 116 patients diagnosed with APE by pulmonary computed tomography angiography or ventilation/perfusion scintigraphy.
