Combined Use of a Modified Microvascular Plug Flow Restrictor and Right Ventricular Outflow Tract Stenting.

ABSTRACT:

Background

The balance of pulmonary and systemic blood flow is the fundamental paradigm that influences decision-making in cardiovascular shunt physiology.

Case summary

This case discusses a term neonate with a prenatal diagnosis of 22q11.2 deletion syndrome and tetralogy of Fallot with near pulmonary atresia, a confluent but severely hypoplastic main pulmonary artery and right pulmonary artery, an isolated left pulmonary artery from the aorta, and major aortopulmonary collateral arteries. Before surgical intervention, a right ventricular outflow tract stent was placed along with a modified microvascular plug (mMVP; Medtronic) to restrict flow in the left pulmonary artery.

Discussion

Recently, there have been case reports using an mMVP as a pulmonary flow restrictor.
