Valvular Atrial Fibrillation (VAF) is a type of atrial fibrillation (AF) that occurs in patients with certain heart valve conditions, such as mitral stenosis or prosthetic heart valves. In VAF, the electrical signals in the heart that control its rhythm become disorganized and chaotic, causing the upper chambers of the heart (atria) to quiver instead of contracting normally. This can lead to symptoms such as palpitations, shortness of breath, fatigue, and chest pain, as well as an increased risk of stroke and heart failure.
Treatment for VAF typically involves managing the underlying valve condition and using medications to control the heart rate and rhythm. In some cases, procedures such as cardioversion, ablation, or implantation of a pacemaker or defibrillator may be necessary. It is important for patients with VAF to work closely with their healthcare team to manage their condition and reduce their risk of complications.« Back to Glossary Index
