SUPPLEMENTARY MATERIAL
Vid.1. A: Selective angiography for residual MBT shunt in a patient with Fallot tetralogy after repair, patient developed heart failure symptoms due to significant left to right shunt. As noted, the MBT arises from LSCA to LPA. MBT: Modified Blalock Taussig shunt. LPA: left pulmonary artery, LSCA: left subclavian artery.
Vid.1. B: The same patient after occlusion of the MBT shunt with vascular plug, there is no residual flow seen after aortic angiography and as noted patient has right aortic arch. MBT: Modified Blalock Taussig shunt.
Vid.2. A: Neo-aortic angiography done for a six months old baby with DORV, sub-pulmonic VSD after arterial switch operation on ECMO support. During neo-aortic injection, the contrast fills the ventricular cavity and coronary arteries are not seen with poor contractility due to significant coronary steal secondary to large fistula between the neo-aorta and RV. RV: right ventricle, VSD: ventricular septal defect, DORV: double outlet right ventricle, ECMO: extracorporeal membrane oxygenation.
Vid.2. B: Selective injection of the AO-RV fistula showing a large fistula stealing blood from neo-aorta to ventricular cavity. Ao: aorta, RV: right ventricle.
Vid.2.C: Neo-aortic injection after the fistula is occluded with vascular plugs showing no residual fistula and no more coronary steal as the left coronary artery is well seen.
Vid.2. D: Neo-aortic injection after the fistula is occluded with vascular plugs showing no residual fistula and no more coronary steal as the right coronary artery is well seen.
