A patient presented with severe right heart failure due to a large LV-to-RA shunt with left-to-right shunting and torrential tricuspid regurgitation 6-weeks following surgical sub-aortic stenosis resection. Retrograde delivery of an Occlutech ventricular septal defect device produced instantaneous resolution of shunt, reduction in tricuspid regurgitation, and impressive diuresis of 28 kg.

Jatrogenic communication between left ventricle and right atrium, known as Gerbode type ventricular septal defect (GVSD) may be observed after different surgical interventions. We present a case of iatrogenic GVSD following complex cardiac surgery including septal myectomy combined with mitral and aortic valve replacement, which was successfully closed percutanously by Occlutech septal occluder.
