Article Abstract
Coronary angiography mostly underestimates coronary artery size. Indian data is scarce on correlating quantitative angiographic coronary diameter (D) to intravascular ultrasound derived coronary diameter (D). We retrospectively analyzed 10-year data (2008-2017) of patients undergoing IVUS guided left main percutaneous coronary intervention (LM-PCI). LM, ostio-proximal LAD (op-LAD), and ostio-proximal LCX (op-LCX) were analyzed in 186, 177 and 44 patients, respectively. A linear correlation was noted between D IVUS and D QCA with derived equations for LM D = 1.68 + 0.69 × D, op-LAD D = 1.91 + 0.53 × D, op- LCX D = 1.93 + 0.49 × D. We conclude that our equations could be used for an approximate estimation of true vessel size in the absence of IVUS assessment.

Anomalous Origin of the Right Coronary Artery from the Left Main Coronary Artery in A Patient with Non-Specific Chest Pain.
Eur J Case Rep Intern Med

Unlabelled: Anomalous origin of the coronary arteries is a rare congenital condition that can present as non-specific chest pain or shortness of breath or remain asymptomatic. Early identification is critical as certain variants are linked with a high risk of sudden cardiac death. Here, we report the case of a 53-year-old female with hypertension, hypothyroidism, obesity (class II) and a history of intermittent chest pain radiating to the left arm for two years.

Aims: Fetal circulation undergoes complex changes in congenital heart disease (CHD) that are challenging to assess with fetal echocardiography. This study aimed to assess clinical feasibility and diagnostic value of 4D flow cardiac magnetic resonance (CMR) in fetal CHD.
Methods And Results: Pregnant women in advanced third trimester pregnancy with fetal CHD were prospectively recruited for fetal CMR between 08/2021 and 11/2024.

Department of Special Education and Communication Disorders, University of Nebraska-Lincoln.
Purpose: This study investigated the effects of age-related hearing decline on functional networks using resting-state functional magnetic resonance imaging (rs-fMRI). The main objective of the present study was to examine resting-state functional connectivity (RSFC) and graph theory-based network efficiency metrics in 49 adults categorized by age and hearing thresholds to identify the neural mechanisms of age-related hearing decline.
Method: Forty-nine adults with self-reported normal hearing underwent pure-tone audiometry and rs-fMRI.
Left Atrial Appendage Occlusion vs Anticoagulants in Dialysis With Atrial Fibrillation.

Department of Internal Medicine, University of Arkansas for Medical Sciences, Little Rock.
Importance: Patients with kidney failure (KF) receiving long-term dialysis have increased incidence of atrial fibrillation (AF). Patients with KF and AF have increased risk of stroke, death, and bleeding compared with age-matched cohorts. In KF, the use of oral anticoagulants (OACs) increases hemorrhage risk, offsetting potential benefits and making left atrial appendage occlusion (LAAO) a potentially promising solution for risk reduction in AF.

The outcome of percutaneous coronary intervention (PCI) compared to coronary artery bypass grafting (CABG) is still controversial for patients with left main coronary artery (LMCA) disease. This multicenter cohort study aimed to evaluate the clinical outcomes of LMCA disease patients who underwent PCI or CABG. We reviewed 875 consecutive patients diagnosed with LMCA disease between January 2009 and December 2020 who underwent coronary revascularization by PCI (n = 404) or CABG (n = 471).
