Coronary angiography: a review of the state of the art and the evolution of angiography in cardio therapeutics.

Traditionally, coronary angiography was restricted to visual estimation of contrast-filled lumen in coronary obstructive diseases. Over the previous decades, considerable development has been made in quantitatively analyzing coronary angiography, significantly improving its accuracy and reproducibility.  Notably, the integration of artificial intelligence (AI) and machine learning into quantitative coronary angiography (QCA) holds promise for further enhancing diagnostic accuracy and predictive capabilities.

Percutaneous closure of aortopulmonary window in a preterm infant.

Aorto-pulmonary window (APW) is a rare congenital heart disease. The non-restrictive types of APWs present at an early age and require early surgical correction. The transcatheter device closure in young infants pose significant challenges that include hemodynamic instability during arteriovenous loop formation and due to potential encroachment of the occlusive device on vital adjacent structures, and sizing of introducer sheaths and delivery systems.

Immersive 3-Dimensional Visualization Aids Transcatheter Management of a Patient With Multiple Pulmonary Arteriovenous Malformations.

Cutting-edge 3-dimensional technologies like 3-dimensional printing and extended reality visualization provide novel, immersive ways to understand and interact with volumetric medical imaging data for preprocedural planning. We present a case that illustrates the utility of these techniques in a patient requiring a complex transcatheter intervention.

Three-dimensional/four-dimensional spatiotemporal image correlation morphology of the ductus arteriosus in fetuses with pulmonary atresia undergoing neonatal ductal stenting.

Background: The value of prenatal identification of morphology of ductus arteriosus in fetuses with congenital heart defects (CHD) with pulmonary atresia and duct-dependent pulmonary circulation (DDPC) in planning neonatal ductal stenting procedure is untested. The aim of the study is to analyze the utility of three-dimensional/four-dimensional (3D/4D) spatiotemporal image correlation (STIC) fetal echocardiography in delineating the morphology of ductus arteriosus in fetuses with DDPC undergoing neonatal ductal stenting.

Methods: In this retrospective study (2017-22), prenatal imaging of pulmonary artery (PA) anatomy, aortic arch sidedness, and morphology of ductus arteriosus (ductal origin was classified as vertical/horizontal and ductal course as tortuous/straight) was done using 3D/4D STIC imaging and volume datasets.
