The Impact of the COVID-19 Pandemic on Coronary Interventional Cardiology Activity in King Abdulaziz Medical City: A Retrospective Study.

Background: The COVID-19 pandemic has decreased the number of patients undergoing coronary interventional procedures. This study aimed to identify the impact of the COVID-19 pandemic on the volume of patients and the types of interventional cardiology procedures performed at King Abdulaziz Cardiac Center (KACC) in Riyadh, Saudi Arabia.

Methods: A retrospective chart review was undertaken with a sample size of 301 patients aged over 18 years, who underwent various cardiac interventions at King Abdulaziz Cardiac Center (KACC) between March 15, 2019, and February 29, 2020 (prior to the pandemic, group A), and between March 1, 2020, and March 15, 2021 (during the pandemic, group B).

Incidence, predictors, and clinical outcomes of permanent pacemaker insertion following transcatheter aortic valve implantation in an Arab population.

Purpose: Conduction defects requiring permanent pacemaker insertion (PPI) are one of the most common complications after transcatheter aortic valve implantation (TAVI). The purpose of this study was to identify the incidence and predictors of this complication as well as to assess clinical outcomes of patients requiring PPI after TAVI in an Arab population.

Methods: In this single-center, retrospective cohort analysis, all patients who underwent TAVI from 2010 to 2018 were reviewed; seventy-four independent variables were collected per patient, and multivariate analysis was performed to identify predictors.
