Congenital Heart Defects

CONGENITAL
HEART DEFECTS

Congenital heart defects are the most common type of birth defect. Defects that involve the wall or vessels of the heart include atrial septal defect (ASD), ventricular septal defect (VSD), and patent ductus arteriosus (PDA). In certain situations, guidelines recommend surgery or transcatheter device closure to repair the defect and prevent complications.¹

Designed for flexibility, our innovative duct occluder options conform to a variety of duct sizes while achieving complete patent ductus arteriosus (PDA) closure from a pulmonary or aortic approach.

Echocardiography and/or angiography can differentiate between PDA and coronary arteriovenous fistulas, which can have a similar presentation.

PDA classification

The Krichenko classification of patent ductus arteriosus, based on angiography, includes 6 types:

PATENT DUCTUS ARTERIOSUS

TYPE A: CONICAL

TYPE D: COMPLEX

TYPE B: WINDOW

TYPE E: ELONGATED

TYPE C: TUBULAR

TYPE F: FETAL

The patent ductus arteriosus can range from a small hemodynamically insignificant lesion that is not heard on auscultation to one that without intervention is large enough to cause congestive heart failure and pulmonary hypertension.^4,8
