Abstract

Patients with adult congenital heart disease (ACHD) have an increased risk of arrhythmic and sudden cardiac death. The subcutaneous implantable cardioverter defibrillator (S-ICD) provides a potentially safer alternative to transvenous ICDs in ACHD. Suitability for S-ICD depends on the surface electrocardiogram (ECG), which is often abnormal in ACHD patients. This study investigates the proportion of ACHD patients who meet the screening criteria for S-ICD implantation. A standard screening ECG was performed in 102 patients with complex ACHD (Tetralogy of Fallot, Fontan circulation, and transposition of the great arteries). This process was repeated postexercise for patients who also had an exercise test. Three quarters (75.4%) of ACHD patients meet screening criteria for an S-ICD with at least one suitable vector. The most common number of acceptable vectors in the eligible group was two (35% of total population). In only 12% of total population, all three vectors were suitable while only one vector was suitable in 28% of total population. The primary vector (equivalent of ECG lead III) was the most common suitable vector, found in 62% of participants who had appropriate sensing vectors. Twenty-five (24.5%) patients failed to me...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
