Melbourne shunt promotes modest growth of central pulmonary arteries leading to complete repair in the majority of patients. There is considerable need for further interventions in these patients to augment the size of the pulmonary arteries.

Jun 8, 2019 · Melbourne shunt promotes growth of diminutive central pulmonary arteries in patients with pulmonary atresia, ventricular septal defect, and systemic-to-pulmonary collateral arteries

Mee shunt (or Melbourne shunt). Used for patients with pulmonary atresia, VSD, and major aortopulmonary collaterals with diminutive PAs. e main PA is disconnected from the heart and anastomosed on and end-to-side fashion to the ascending aorta in order to promote growth of the branch PAs and allow for future reconstruction. is procedure can be ...

The first procedure is a central end-to-side aortopulmonary shunt (Melbourne shunt) intended to cause growth and development of the central pulmonary arteries. We subsequently measured central pulmonary artery growth after Melbourne shunt.

The Melbourne group [17, 18] advocates a strict rehabilitation policy supporting an early approach with the central shunt, followed by reassessment of pulmonary artery growth, conversion to an RV-to-pulmonary artery conduit, and hopefully complete repair with or without augmentation of the pulmonary artery branches.

Melbourne shunt: side-biting clamp con-trols the ascending aorta; soft clamps control the branch pulmonary arteries. Inset demonstrates the completed shunt with the pulmonary artery anastomosed to the posterior and left lateral as-pect of the …

In this situation, a direct aortopulmonary connection can be made (the so-called Melbourne Shunt), 10 connecting the diminutive PAs directly into the back of the aorta with or without a small interposition shunt (Fig. 5). The vessels are usually so small that …

In this study, we present our experience with the central aortopulmonary shunt technique with interposing a polytetrafluoroethylene graft between main pulmonary artery (end-to-end) and the ascending aorta (side-to-side) in a variety of cyanotic congenital heart defects.

The Melbourne shunt is short and narrow, and typically originates from the posterior ascending aorta. It is almost always necessary to heat shape a catheter in order to successfully engage the shunt and direct a guidewire into one of the pulmonary artery branches.

Sep 1, 2003 · Melbourne shunt: side-biting clamp controls the ascending aorta; soft clamps control the branch pulmonary arteries. Inset demonstrates the completed shunt with the pulmonary artery anastomosed to the posterior and left lateral aspect of the ascending aorta close to the sinotubular junction.
