Explanatory deep learning to predict elevated pulmonary artery pressure in children with ventricular septal defects using standard chest x-rays: a novel approach

Frontiers in Cardiovascular Medicine

Objective Early risk assessment of pulmonary arterial hypertension (PAH) in patients with congenital heart disease (CHD) is crucial to ensure timely treatment. We hypothesize that applying artificial intelligence (AI) to chest x-rays (CXRs) could identify the future risk of PAH in patients with ventricular septal defect (VSD).

Crochetage sign on ECG in ASD ECG in ASD with severe pulmonary hypertension: Tall R’ in V1, ST depression in inferior leads and V2-V5, and T inversion in inferior leads and V1-V6 are seen. The sign has been described in VSD with biventricular hypertrophy in children.

Corvia atrial shunt system: Mean LA pressure reduction device in HFpEF

Dr. S. Venkatesan MD

This is to create a small regulatory orifice in the IAS ( A complicated term for a small ASD ) to decompress the LA and reduce pulmonary congestive symptoms. Curious minds might ask, can’t we decompress LV it self by creating a small VSD. Antonio F Corno, et al JTVS 200 3 Remote controlled pulmonary artery banding

The VSD is partly overrided by the aorta. And if it is more than 50% towards the right side, then you think of another condition known as double outlet right ventricle, where both great vessels, aorta and pulmonary artery arises from the right ventricle. You require multiple views to see from where the pulmonary arteries are arising.

Right atrial hypertrophy as in tricuspid stenosis, pulmonary stenosis and pulmonary hypertension. But in a VSD with pulmonary hypertension A wave is not prominent. So a prominent A wave in a complex congenital heart disease situation would indicate that interventricular septum is intact.
