Arrhythmias are a major cause of morbidity and sudden death in patients with congenital and acquired valvar disease, highlighting the need for arrhythmia surveillance in high-risk lesions.
This review emphasizes the critical need for arrhythmia surveillance in patients with congenital and acquired valvar disease to prevent sudden death and heart failure.
Supports arrhythmia vigilance in valvar disease; leaves open optimal prevention strategies.
Valvar heart disease can be complicated by hemodynamic derangements, depending on the degree of the abnormality. Stenosis causes pressure overload of the chamber draining through the valve and regurgitation results in volume overload. Many lesions have a component of both, resulting in both pressure and volume overload. Increased wall stress causes myocardial stretching and fibrosis, resulting in scarring; a nidus for arrhythmia development. Arrhythmias can complicate the clinical picture and increase the morbidity and mortality in patients with both congenital and acquired valvar disease. In adults with congenital heart disease, arrhythmias are the most common cause of sudden death, followed by heart failure. Valvar stenosis and insufficiency certainly contribute to this. This article highlights the need for arrhythmia surveillance for high-risk valvar lesions.
