Article Synopsis
- The study investigated the clinical features and long-term outcomes of myocarditis linked to COVID-19 vaccination, focusing on 333 affected patients under 30 compared to 100 with MIS-C.
- Findings indicated that C-VAM patients were mostly young white males, experienced milder symptoms initially, but had higher rates of myocardial injury as shown by cardiac imaging.
- Despite a generally benign course and no reported cardiac deaths during follow-up, 60% of patients still showed evidence of myocardial injury after approximately six months.
Background: Thromboembolic events related to invasive electrophysiology studies, while rare, can have devastating consequences. Use of systemic anticoagulation for a pediatric or adult-congenital invasive electrophysiology study is recommended, however there is no established standard of practice in this population.
Objective: To report on procedural practices for thromboembolism prophylaxis during invasive electrophysiology studies for pediatric patients and adults with congenital heart disease.
