A study on the mortality and complication rates following percutaneously adjustable pulmonary artery banding

Transcatheter balloon angioplasty of internal pulmonary artery bands to improve pulmonary blood flow: a case series

Pulmonary artery banding (PAB) is used to restrict pulmonary blood flow in select patients with large left-to-right intracardiac shunts or unrestrictive pulmonary blood flow prior to eventual surgical repair or palliation. More recently, surgical placement of an internal or intraluminal PAB (IPAB) has been used to restrict pulmonary circulation. Here we present two patients who underwent balloon angioplasty of the IPAB to treat cyanosis and improve pulmonary blood flow.

Congenital heart disease: addressing the need for novel lower-risk percutaneous interventional strategies

INTRODUCTION

With the advent of improved neonatal care, increasingly vulnerable higher-risk patients with complex congenital heart anomalies are presenting for intervention. This group of patients will always have a higher risk of an adverse event during a procedure but by recognising this risk and with the introduction risk scoring systems and thus the development of novel lower risk procedures, the rate of adverse events can be reduced.

AREA COVERED

This article reviews risk scoring systems for congenital catheterization and demonstrates how they can be used to reduce the rate of adverse events. Then novel low risk strategies are discussed for low weight infants e.g. patent ductus arteriosus (PDA) stent insertion; premature infants e.g. PDA device closure; and transcatheter pulmonary valve replacement. Finally, how risk is assessed and managed within the inherent bias of an institution is discussed.

EXPERT OPINION

There has been a remarkable improvement in the rate of adverse events in congenital cardiac interventions but now, as the benchmark of mortality rate is switched to morbidity and quality of life, continued innovation into lower risk strategies and understanding inherent bias when assessing risk will be key to continuing this improvement.
