Anatomical variations of pulmonary artery and associated cardiac defects in Tetralogy of Fallot.
TLDR
Isolated LPA origin stenosis and MPA hypoplasia were the most common abnormalities and significant associated cardiac lesions were present in one-third of the patients and included PDA, additional muscular VSD, coronary artery abnormalities and MAPCA.Abstract:
Objective: To determine pulmonary artery variations and other associated cardiac defects in patients with Tetralogy of Fallot (TOF). Study Design: Cross-sectional, descriptive study. Place and Duration of Study: The Children’s Hospital and the Institute of Child Health, Lahore, from April 2006 to October 2007. Methodology: All patients with TOF, who underwent cardiac catheterization during this period, were included. Standard cine-angiograms were recorded and pulmonary artery sizing was done using z-scoring. Results: A total of 216 patients with TOF were catheterized. Pulmonary Artery (PA) abnormalities were present in 84 (38.9%) patients. The commonest abnormality was isolated Left Pulmonary Artery (LPA) stenosis (n=27, 32.14%) followed by isolated hypoplasia of Main Pulmonary Artery (MPA) (n=18, 21.43%) and supra-valvular stenosis in (n=11, 13.1%) patients. LPA was absent in one patient, while 2 patients had both absent right and left PA with segmental branch pulmonary arteries originating directly from MPA. Associated cardiac lesions included right aortic arch in 34 (15%), additional muscular VSD vary in 13 (5.5%), Patent Ductus Arteriosus (PDA) in 11 (6%) and Major Aortopulmonary Collateral Arteries (MAPCA) in 2 (1.9%) patients. Significant coronary artery abnormality was present in 10 (4.6%) children. Conclusion: Pulmonary artery abnormalities were present in 38.9% of patients with TOF. Isolated LPA origin stenosis and MPA hypoplasia were the most common abnormalities. Significant associated cardiac lesions were present in one-third of the patients and included PDA, additional muscular VSD, coronary artery abnormalities and MAPCA.read more

The fetal ductus arteriosus and its abnormalities--a review.
TL;DR: Understanding the transcriptional regulation of normal DA development, maturation, and closure of the arterial duct as well as the hemodynamic changes during pregnancy and after delivery may provide additional targets for rational drug design to either close or open the DA, both antenatally and postnatally.

Variations of pulmonary arteries and other associated defects in Tetralogy of Fallot
TL;DR: Isolated Left Pulmonary Artery origin stenosis was the most common abnormality and significant associated cardiac lesions including Patent Ductus Arteriosus, additional muscular Ventricular Septal Defect, coronary artery abnormalities, bilateral Superior Vena Cava, Atrial Septal defect and Major Aortopulmonary Collateral Arteries were present in one-third of the patients.

Presurgical planning using image-based in silico anatomical and functional characterization of Tetralogy of Fallot with associated anomalies
TL;DR: It is hypothesized that patient-specific computed tomography-based morphometry followed by in silico reconstruction of viable surgical options with haemodynamic function assessment using computational fluid dynamics (CFD) can guide surgical decisions and help forecast functional outcomes without invasive measurements.

TL;DR: DA enlargement was often associated with left-sided obstructive CHD, whereas a small DA and reverse blood flow often indicated the presence of right-sided obstructionist CHD.
