Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The most common congenital heart disease is the ventricular septal defect, and after surgical closure of a such defect, an arrythmia called the right bundle branch block, is very frequent. Therefore the aim of this study is to investigate if this group of patients has inferior outcomes compared to the group without this arrythmia after surgical closure and compared to a group of healthy control subjects. All patients will be undergoing 1. exercise testing, 2. echocardiography, 3. echocardiography during exercise, and 4. MRI. The perspective is the ability to point out a group of patients with a possible need of further intervention, and additionally to increase the awareness of protecting the electrical system of the heart during the operation.
