• LVD can rarely present in the subaortic position. • A muscular LVD has synchronous contraction; an aneurysm does not. • Subaortic LVD may be associated with aortic regurgitation, thrombus, and arrhythmia. • An isolated LVD may be followed conservatively with noninvasive imaging.

Objective: To analyze the results of surgical treatment of discrete subaortic stenosis and identify the main factors of left ventricular outflow tract (LVOT) restenosis in long-term postoperative period.
Material And Methods: There were 87 surgical interventions in 63 patients with congenital subaortic stenosis between 2008 and 2023. Mean preoperative peak systolic LVOT pressure gradient was 72 mmHg (50-110 mmHg).

Background: The Mustard and Senning operations for dextro-transposition of the great arteries (D-TGA) establish a biventricular physiology with a subaortic right ventricle (sRV). While prolonged QRS has been associated with worse prognosis in these patients, current echocardiographic tools fall short in adequately assessing the (mal)performance and function decline of the sRV during follow-up. The present study is the first to characterize Myocardial Work (MW) indices of the sRV in D-TGA patients after Mustard/Senning repair.

Introduction And Clinical Importance: Shone complex (SC) is a rare multilevel congenital heart disease (CHD) characterized by four left-sided heart obstructive lesions: parachute mitral valve, supravalvular mitral ring, subaortic stenosis, and coarctation of the aorta (CoA), accounting for 0.6-0.7 % of CHD cases.

In this study, we propose a new method for bioprinting 3D Spheroids to study complex congenital heart disease known as discrete subaortic stenosis (DSS). The bioprinter allows us to manipulate the extrusion pressure to change the size of the spheroids, and the alginate porosity increases in size over time. The spheroids are composed of human umbilical vein endothelial cells (HUVECs), and we demonstrated that pressure and time during the bioprinting process can modulate the diameter of the spheroids.
