Systematic Occlusion of Shunts

Spontaneous occlusion of systemic-to-pulmonary arterial shunts.

M OTZ. AND HIS COLLEAGUES ADDRESS AN OLD, but still important problem, namely spontaneous occlusion of systemic-topulmonary arterial shunts. With the current emphasis on neonatal repair, as opposed to staging operations, the focus of this discussion has shifted from tetralogy of Fallot and its related lesions to hypoplastic left heart syndrome. Patients undergoing the Norwood operation now comp...

Residual and recurrent shunts after implantation of Cook detachable duct occlusion coils.

OBJECTIVE To assess the presence and outcome of Doppler detectable shunts following implantation of the Cook detachable PDA coil. DESIGN Prospective study. SETTING Tertiary paediatric cardiac centre. PATIENTS 76 consecutive patients undergoing coil implantation (80 procedures). MAIN OUTCOME MEASURES Detection and colour Doppler echocardiographic appearance of residual or recurrent shunt...

Balloon occlusion of the carotid artery for the angiographic visualization of Blalock-Taussig shunts and pulmonary arteries.

We describe the use of a balloon catheter to occlude the right or left carotid artery as a way of directing contrast material to the pulmonary arteries. This procedure was carried out in the postoperative study of 14 children who had undergone a Blalock-Taussig shunt. The method was reliable, and the angiograms provided excellent visualization of the pulmonary arteries using only small volumes ...

A Systematic Review of Acquired Left Ventricle to Right Atrium Shunts (Gerbode Defects).

T he left ventricle-right atrium (LVRA) shunt, a rare and special type of ventricular septal defect (VSD), was first reported by Gerbode et al1 in 1958, and was thus termed “Gerbode defect”, after the first author. In 1967, Riemenschneider and Moss2 classified Gerbode defects into two types: direct (or true) and indirect (or false). The direct type is a direct shunt between the left ventricle a...
