U.S., July 16 -- ClinicalTrials.gov registry received information related to the study (NCT07065123) titled 'Study on Heart Block Risks Using Outcome-Based Modeling' on June 26.
Brief Summary: This study developed a prediction model for high-grade atrioventricular block (AVB) and complete left bundle branch block (CLBBB) following transcatheter aortic valve replacement (TAVR) in Chinese patients with aortic stenosis (AS). Analyzing 112 patients from Sun Yat-sen Memorial Hospital (2017-2024), the study incorporated clinical, electrocardiographic, and procedural variables to identify risk factors via logistic regression.
