Noninvasive assessment of myocardial perfusion using ultrafast ultrasound: clinical study for congenital heart disease.

ABSTRACT:

Aims

Myocardial perfusion impacts cardiac function following surgical repair of critical congenital heart disease (CCHD). Temporal variation assessment of myocardial blood volume throughout the cardiac cycle can be a surrogate for perfusion. Ultrafast power Doppler (UPD) is an ultrasound imaging technique capable of noninvasively quantifying myocardial blood volume changes. The objective of this study is to demonstrate the feasibility of perioperative transthoracic UPD assessment and to determine if UPD reflects physiologic changes in myocardial perfusion.

Methods and results

Five neonatal transposition of the great arteries (TGA) undergoing arterial switch operation (ASO), five hypoplastic left heart syndrome (HLHS) undergoing Stage 1 palliation (S1P), and five age/weight-m
