Comparative, multidimensional imaging of patent ductus arteriosus and a proposed update to the morphology classification system for dogs.

ABSTRACT:

Background

Accurately assessing the morphology and shape of the patent ductus arteriosus (PDA) and obtaining measurements are important to avoid procedural complications.

Objectives

To characterize and compare PDA morphology, shape, and dimensions with angiography and echocardiography.

Animals

25 client-owned dogs with echocardiographically confirmed PDA.

Methods

Prospective case series. Imaging consisted of single plane angiography, transthoracic echocardiography from the right (TTE-R) and left (TTE-L), and two-dimensional, biplane, and three-dimensional transesophageal echocardiography (TEE-2D and TEE-3D). Measurements included angiographic minimal ductal diameter (MDD), echocardiographic pulmonary ostium in a single dimension (TTE-R, TTE-L, and TEE-2D) and i
