Abstract:
The use of self-expanding valve platforms in the setting of regurgitant native right ventricular outflow tracts is progressing rapidly, promising the potential of lifetime percutaneous therapy for some patients who previously had been committed to sternotomy with cardiopulmonary bypass surgery. These developments have been associated with some unpredicted complications whose aetiologies are now starting to develop into patterns which may be related to valve design as well as specific patient anatomic substrates. We report the case of an iatrogenic communication from the RVOT into the right coronary sinus by a Harmony valve in a patient whose original diagnosis was pulmonary stenosis with a small ventricular septal defect.

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...
