Abstract Coronary artery disease (CAD) is one of the most authentic cardiovascular afflictions because it is an uncommonly overwhelming heart issue. The breakdown of coronary cardiovascular disease is one of the principal sources of death all over the world. Cardiovascular deterioration is a challenge, especially in youthful and rural countries where there is an absence of human-trained professionals. Since heart diseases happen without apparent signs, high-level detection is desirable. This paper proposed a robust and tuned random forest model using the randomized grid search technique to predict CAD. The proposed framework increases the ability of CAD… More >

Abstract Coronary artery disease (CAD) has become a significant cause of heart attack, especially among those 40 years old or younger. There is a need to develop new technologies and methods to deal with this disease. Many researchers have proposed image processing-based solutions for CAD diagnosis, but achieving highly accurate results for angiogram segmentation is still a challenge. Several different types of angiograms are adopted for CAD diagnosis. This paper proposes an approach for image segmentation using Convolution Neural Networks (CNN) for diagnosing coronary artery disease to achieve state-of-the-art results. We have collected the 2D X-ray… More >

Abstract Coronary artery disease (CAD) is one of the most common pathological conditions and the major global cause of death. Myocardial perfusion imaging (MPI) using single-photon emission computed tomography (SPECT) is a non-invasive method and plays an essential role in diagnosing CAD. However, there is currently a shortage of doctors who can diagnose using SPECT-MPI in developing countries, especially Vietnam. Research on deploying machine learning and deep learning in supporting CAD diagnosis has been noticed for a long time. However, these methods require a large dataset and are therefore time-consuming and labor-intensive. This study aims to… More >

Abstract Background: Mechanisms and clinical manifestations of coronary artery complications after right ventricular outflow tract reconstruction surgery are not well known. Methods: Patients who had coronary artery complications after pulmonary valve replacement or the Rastelli procedure at a single tertiary centre were retrospectively analysed. Results: Coronary artery complications were identified in 20 patients who underwent right ventricular outflow tract reconstruction surgery. The median age at diagnosis of coronary artery complication was 21 years (interquartile range: 13–25 years). Mechanisms of coronary artery complications were compression by adjacent materials in 12 patients, dynamic compression of intramural course of coronary artery… More >

Abstract Coronary artery disease (CAD) remains a major reason for increased mortality over the globe, comprising myocardial infarction and ischemic cardiomyopathy. The CAD is highly linked to coronary stenosis owing to the encumbrance of atherosclerotic plaques. Particularly, diversified atherosclerotic plaques are highly responsible for major cardiac adverse events over the calcified and non-calcified plaques. There, the recognition and classification of atherosclerotic plaques play a vital role to prevent and intervene in CAD. The process of detecting various class labels of the atherosclerotic plaques is significant to identify the disease at the earlier stages. Since several automated… More >

Abstract A single coronary artery is a very rare condition, commonly associated with other congenital anomalies. It could be generally considered as neither benign nor malignant form of congenital coronary artery anomalies since its pathophysiological and clinical implications grossly depend on different anatomical patterns defined by the site of origin and distribution of the branches. By presenting the patient who underwent successful coronary artery bypass grafting and aortic valve replacement surgery in a presence of isolated single coronary artery, we intend to emphasize natural and procedural risks and distinguish casual from causal in this extremely rare More >

Abstract Objective: Acquired coronary artery disease, initially thought to rarely affect survivors of congenital heart disease, is increasingly recognized in this population, as these patients grow in age and numbers in the recent era. This study reports our experience with coronary artery disease in adults with congenital heart disease and discusses treatment issues and the existing literature. Methods: Retrospective review of all charts of adults with congenital heart disease and acquired coronary artery disease was performed. Patients’ clinical characteristics, diagnosis, risk factors, noninvasive and invasive imaging and management data were recorded. Results: Coronary artery disease was diagnosed at… More >

Abstract Pharmacologic stress cardiovascular magnetic resonance (PSCMR) is a wellestablished and reliable diagnostic tool for evaluation of coronary artery disease in the adult population. Stress imaging overall and PSCMR in particular is less utilized in the pediatric population with limited reported data. In this review, we highlight the potential use of PSCMR in specific pediatric cohorts with congenital and acquired heart disease, and we review the reported experience. A suggested protocol is presented in addition to two case examples of patients with Kawasaki disease where PSCMR aided decision making. More >

Abstract Objective: As adults with congenital heart disease (CHD) grow older, preoperative screening for coronary artery disease (CAD) may be indicated prior to CHD surgery. Data regarding the indications for preoperative CAD screening in this population are limited. Current practice is to follow guidelines for patients with valvular heart dis‐ ease; however, the risk for CAD in certain congenital heart diagnoses may be higher than the general population. This study aimed to assess the results of preoperative CAD screening in patients prior to CHD surgery.
Design: Retrospective study.
Setting: Single tertiary center.
Patients: Patients ≥35 years that had CHD surgery… More >

Abstract Background: There are limited data about outcomes of coronary artery disease (CAD) in adults with repaired tetralogy of Fallot (TOF). The purpose of this study was to describe the prevalence and treatment of CAD in adults with TOF, and the impact of CAD on long‐term survival.
Methods: Retrospective review of MACHD database for adults with repaired TOF who underwent aortic root/selective coronary angiogram, 1990‐2017. Patients were categorized into three groups: (1) No CAD defined as normal coronary angiogram; (2) Mild CAD defined as ≤50% stenosis in all vessels; and, (3) Significant CAD defined as >50% stenosis in… More >
