Approximately 50% of individuals eligible for transcatheter aortic valve implantation (TAVI) have coronary artery disease (CAD). The influence of CAD, both its prevalence and severity, on post-TAVI clinical results has yielded conflicting findings. Recent research has shown positive results for the use of computed tomography angiography and functional percutaneous evaluation of coronary lesions in the pre-TAVI assessment, besides the classic coronary angiography.

Esophageal injury is a serious complication following atrial fibrillation catheter ablation procedures. It may manifest as atrio-esophageal fistula, pericardio-esophageal fistula (PEF), or restricted perforation, with high mortality rate if left unoperated. Chest computed tomography with intravenous contrast is the mainstay of diagnosis; however, a definite imaging diagnosis is often delayed and may worsen patient outcomes.

Background: Distal radial artery access (DRA) has been emerged as an alternative for conventional transradial arterial access. While palpation of radial artery is mandatory prior coronary angiography, it remains unknown the clinical impact of palpation in DRA success. Aim of our study is to explore whether the palpability of distal radial artery is linked with higher rates of successful arterial access.

Article Synopsis
  • * Results show that COVID-19 patients had a significantly lower LnRHI two months after discharge compared to matched controls, indicating persistent endothelial dysfunction.
  • * The study found that a high percentage of COVID-19 patients exhibited endothelial dysfunction during hospitalization and at six months later, but there were no significant differences in thrombotic events, cardiovascular complications, or mortality between the two groups.
