Abstract:
A patient with permanent atrial fibrillation, triple mechanical prosthetic valve replacements, and nonischemic cardiomyopathy presented with symptomatic high-grade atrioventricular block. A transvenous implantable cardioverter-defibrillator system was achieved with the defibrillator lead and bipolar pace-sense lead in separate anterolateral branches of the coronary sinus with successful defibrillation testing.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
