Abstract:
During transcatheter pulmonary valve placement, coronary compression observed during simultaneous right ventricular outflow tract angioplasty and coronary angiography typically contraindicates valve implantation. We present a unique patient with tetralogy of Fallot who underwent successful transcatheter Melody valve placement despite coronary compression observed during right ventricular outflow tract balloon angioplasty.
