Multimodality hemodynamic evaluation for optimizing management of anomalous origin of the right pulmonary artery from the aorta in an adolescent.

The hemodynamics of anomalous origin of the pulmonary artery (PA) from the aorta is challenging. Different sources of blood supply to the lungs lead to a unique state of differential flow, pressure, and pulmonary vascular resistance in each lung. The decision for surgical reimplantation of the anomalous PA during infancy is easy.

Tetralogy of Fallot with coronary crossing the right ventricular outflow tract: A tale of a bridge and the artery.

A coronary artery crossing the right ventricular outflow tract is a subset of a larger pathomorphological cohort known as an anomalous coronary artery (ACA) in the tetralogy of Fallot (TOF). The best possible outcome in a patient with TOF and ACA is decided by judicious selection of optimum preoperative investigative information, the timing of surgery, astute assessment of preoperative surgical findings, and appropriate surgical technique from a wide array of choices. In most instances, the choice of surgical technique is determined by the size of the pulmonary annulus and the anatomical relation of ACA to the pulmonary annulus.

Where are we after 50 years of the Fontan operation?

First introduced in 1971, the Fontan procedure is the final common destination for all patients with a functional single ventricle. The procedure itself has evolved tremendously over the last five decades. This review traces this journey and presents the importance, outcomes and future outlook of the procedure in the current era.

Systolic excursion of the leaflets of the truncal valve: An unusual mechanism for pulmonary stenosis in common arterial trunk.

Background: Pulmonary stenosis in patients with common arterial trunk protects the pulmonary vasculature. In our recently published prospective study of common arterial trunk, some patients with sinusal origin of the pulmonary arterial segment had pulmonary stenosis induced by systolic excursion of a truncal valvar leaflet. We aimed to determine the detailed morphologic characteristics of this unusual finding.

Clarifying the anatomy of common arterial trunk: a clinical study of 70 patients.

Aims: Anatomic variations in hearts with common arterial trunk are well-known, although there is no large study of living patients. Detailed knowledge of the origins of the pulmonary and coronary arteries is vital for surgical management. We sought to clarify the variations using computed tomography.
