We investigated infants with Kawasaki disease, congenital coronary artery fistulas and anomalous origin of the left coronary artery from the pulmonary trunc (Bland-White-Garland syndrome) by 2-dimensional and Doppler echocardiography. We describe the systematic approach for visualizing in detail coronary anatomy by two-dimensional echocardiography. Our results suggest that this echocardiographic technique is useful for detecting coronary anomalies and has a great rolbefore angiocardiography especially in sick babies. We recommend performing 2-dimensional echocardiography in the acute and chronic stage of Kawasaki disease for evaluating coronary arterial aneurysms.

Swine are increasingly utilized in cardiovascular research due to their anatomical and physiological similarities to humans, particularly for studying diastolic dysfunction. While MRI offers excellent structural imaging, echocardiography provides superior real-time assessment of diastolic parameters. To address the lack of standardized methods and reduce variability across studies, we present a comprehensive guide for performing echocardiography in Yorkshire pigs, detailing anatomical considerations, equipment requirements, and technical approaches.

Background: Superior caval vein obstruction is a rare complication of endocardial pacing lead implantation that can result in a right to left shunt.
Case Summary: A 3-year-old child with type 2 Brugada syndrome presented with mild cyanosis post-endocardial pacing implantation due to evolutionary right superior caval vein obstruction. This obstruction resulted in a right to left shunt across a previously unrecognized patent levo-atrial cardinal vein associated with partial anomalous pulmonary venous drainage.

Background: This study aimed to assess the accuracy of tricuspid spectral Doppler (E/A) and tissue Doppler parameters (E/E') to diagnose right ventricular diastolic dysfunction (RVDD) in comparison to American Society of Echocardiography (ASE criteria) in pediatric tetralogy of Fallot (TOF) patients after surgical repair.
Methods: This prospective, observational study was done at a tertiary care hospital involving 40 pediatric TOF patients aged less than 2 years who underwent complete intracardiac repair with cardiopulmonary bypass (CPB). Echocardiographic observations were made using a pediatric transesophageal echocardiography probe after surgical repair in the post-CPB period.

Background: In patients with secondary tricuspid regurgitation (STR), right ventricular ejection fraction (RVEF) may not accurately reflect the actual RV systolic performance since a considerable amount of the RV stroke volume (SV) is regurgitated back into the right atrium. To overcome this limitation, we explored the association with the outcome of the effective RVEF (eRVEF), which accounts for the tricuspid regurgitant volume (RegVol).
Methods: 513 patients with STR (mean age 75±13 years, 39% atrial STR, 58% severe) underwent complete two-, three-dimensional, and Doppler echocardiography.

Aims: Although an association between the systemic circulation and transaortic flow rate (TFR) is frequently hypothesized in patients with aortic stenosis (AS), it has not been demonstrated previously. We sought to explore the relationship between blood pressure (BP), vascular afterload measures, clinical history of hypertension, TFR, and survival in patients with severe AS (aortic valve area ≤ 1 cm²).
Methods And Results: We studied 323 patients ≥ 65 years (110 prospective, 213 registry analysis) who underwent transcatheter aortic valve replacement over a 5-year period.
