Abnormalities of left ventricular inflow and outflow

Abstract

Congenital abnormalities of left ventricular inflow and outflow include abnormalities of the left atrium, mitral valve (supravalvar, valvar, and subvalvar), and abnormalities of the left ventricular outflow tract, the aortic valve, and supravalvar area. Cardiac magnetic resonance imaging (CMR) has become an important adjunctive tool in evaluating and following patients with this group of anomalies. This chapter reviews the role of CMR in the care of patients with congenital abnormalities of left ventricular inflow and outflow. In addition to describing the morphologic abnormalities and their clinical presentations, the indications and limitations of CMR in each condition are discussed and a suggested CMR examination protocol is provided.
