To evaluate the feasibility and accuracy of magnetic resonance (MR) coronary angiography for detection artery anomalies in infants children by using surgical findings as a reference.The data analysis was approved institutional review board. One hundred with congenital heart disease underwent MR while under general anesthesia (mean age ± standard deviation, 3.9 years 3; range, 0.2-11 years). A navigator-gated, T2-prepared, three-dimensional steady-state free precession whole-heart protocol...
To compare left ventricular (LV) volume and mass assessment using two-dimensional (2D) cine steady-state free precession (SSFP) k-t space broad-use linear acquisition speed-up technique (k-t BLAST) accelerated 3D magnetic resonance imaging (MRI).On a commercially available 1.5T MR scanner, 2D SSFP, six- eight-fold BLAST were performed to evaluate LV volumes in 17 volunteers. After semiautomatic segmentation of the different data sets, resulting compared according mean difference, 95%...
Objective We aimed to study the efficiency and safety of once-a-week outpatient rehabilitation followed by home program with tele-monitoring in patients complex cyanotic congenital heart disease. Design Prospective nonrandomized study. Method Patients who have been diagnosed either Eisenmenger's syndrome or inoperable disease able attend 12-week cardiac were included. Training treadmill walking bicycling under supervision at unit first 6 weeks home-based exercise (bicycle walking) a target...
To evaluate the influence of heart rate variability on image quality in patients with suspected coronary artery disease during magnetic resonance angiography (MRCA).The images from 70 who underwent target-volume MRA were retrospectively analyzed. Two independent observers evaluated using a score 0 (nonvisible) to 4 (excellent quality). Images grouped into good (score > 2) and poor 0-2). Five parameters (effective scan duration, navigator efficiency, mean rate, acquisition window,...
Four-dimensional phase-contrast (PC) velocity-encoded flow magnetic resonance imaging (4D MRI) is a potentially valuable tool for studying cardiovascular hemodynamics disease monitoring and/or treatment planning. In this study we compared the performance of two 4D MRI pulse sequences - echo-planar (EPI) and segmented gradient-echo (turbo-field-echo or TFE on vendor's platform) clinical 3T system in 6 human subjects including 3 patients with Tetralogy Fallot (TOF). For aortic rate,...
Abstract We evaluated early outcomes of transcatheter valve‐in‐valve (ViV) implantation in patients with degenerated bio‐prosthesis tricuspid position. Total 5 were included our case series. Baseline native valve etiology highly varied ranging from chest wall trauma, Ebstein anomaly, rheumatic heart disease, infective endocarditis and complex congenital disease. These differences also made patient comorbidities varied. Procedure details due to different clinical technical challenges. All...
Background Fragmented QRS (fQRS) is a common EKG findings in general population. It has emerged as the independent predictor for cardiac events and all-cause mortality patients with known coronary artery disease. However, none of study evaluated role fQRS without Q-wave on EKG. We aimed to evaluate whether function myocardial scar using MRI imaging tool. Methods 250 who underwent stress were included. The 12-lead was analyzed by two observers. defined presence an additional R wave (R’) or...
Abstract Background Ischemic cardiomyopathy is a high-cost, resource-intensive public health burden that associated with 1-year mortality rate of about 16% in western population. Different patient ethnicity and pattern practice may impact the clinical outcome. We aim to determine identify factors significantly predicts Thai patients ischemic cardiomyopathy. Methods This prospective multicenter registry enrolled consecutive were diagnosed at 9 institutions located across Thailand. Patients...
Calcium calcification in the wall of arteries (CAC) leads to a higher risk atherosclerosis related outcomes, especially myocardial infarction (MI). Nevertheless, causal role CAC on other outcomes is unclear. In this study, we used Mendelian randomization (MR) systematically investigate across broad range atherosclerotic cardiovascular diseases including coronary heart disease, angina, MI, ischemic stroke, and peripheral vascular disease. Publicly available data from UK biobank sources were...
Abstract Background In patients with ischemic heart disease (IHD), many studies demonstrated an association between fragmented QRS complex (fQRS) on 12‐lead ECG and myocardial scar, failure, increased mortality. However, data in adults without history of IHD is limited. We aimed to evaluate whether there fQRS diagnosed by stress cardiac MRI. Method retrospectively reviewed demographic data, ECG, MRI from 604 patients. Fragmented was defined as the presence additional R wave (R’), notching...
Hypertrophic cardiomyopathy (HCM) and dilated (DCM) are the most common referrals in Inherited Cardiovascular Condition (ICC) Genetics Service. Several issues must be discussed with patients their families during genetic consultation session, including options for testing cardiovascular surveillance family members. We developed an ICC registry performed next-generation-based DNA sequencing all affected by non-syndromic HCM idiopathic DCM our joint specialist genetics service. The target gene...
Methods 100 patients (median age 3 years, range 4 months–11 yrs) with congenital heart disease were imaged Philips Intera 1.5 T MR scanner under general anesthesia. After injection of contrast (Magnevist 0.2 mmol/kg), a vector cardiogram-triggered, free-breathing, 3D-SSFP whole-heart approach navigator gating (3 mm) was used nearly isotropic image resolution (table 1). The acquisition window adapted to the resting period heart. Image quality left and right coronary arteries assessed by two...
Introduction:In Thailand, the radiofrequency catheter ablation among arrhythmia with congenital heart disease was limited. Methods:The retrospective study symptomatic arrhythmic for procedure during 1 January 1996 until 31 December, 2017.Clinical data, were classified. Result: The inRamathibodi hospital 29 patients There male 11 (37.9%)patients, mean age 36.3 years old, ASD 10 (34.5%) and Ebstein's anormaly 9 (31.0%)patients, respectively.The efficacy of treatment 95.1%.The most common...
Objectives To compare a standard sequential 2D Planning Method (2D-PM) with 3D offline (3D-PM) based on contrast-enhanced magnetic resonance angiography (CE-MRA) in children congenital heart disease (CHD). Design In 14 complex CHD (mean: 2.6 years, range: 3 months to 7.6 years), axial and coronal cuts were obtained single slice spin echo sequences get the final double oblique longitudinal cut of targeted anatomical structure (2D-PM, n = 31). On separate workstation, similar maximal intensity...
