Figure 1 (A) Neonatal aortic angiogram performed 26 h after stage I palliative surgery for hypoplastic left heart syndrome shows complete occlusion of right modified Blalock-Taussig shunt (mBTS) (white arrowhead). Note the venous (black asterisk) and arterial (white asterisk) cardiopulmonary support cannulas. (B) The occluded shunt has been crossed with a hydrophilic guide wire, and a 3.5-mm angioplasty balloon is inflated. Note the balloon is inflated across two recently created suture lines on either end of the mBTS. (C) Innominate artery angiogram after recanalization. The mBTS is patent, and there is no evidence of suture line disruption.

Figure 2 (A) Right ventricular angiogram performed via a sheath (black asterisk) placed directly into the right ventricular outflow tract (RVOT) via an open sternum in a four-month-old 6 h after RVOT reconstruction and pulmonary arterioplasty. Note the severe proximal left pulmonary artery stenosis (black arrowhead) at the anastomosis with the RVOT patch. (B) After stent placement, there has been complete relief of the stenosis without evidence for vascular disruption.
