A Common Polymorphism in the MTHFD1 Gene Is a Modulator of Risk of Congenital Heart Disease. J Cardiovasc Dev Dis 2022; 9:jcdd9060166. [PMID: 35735795 PMCID: PMC9224796 DOI: 10.3390/jcdd9060166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2022] [Revised: 05/19/2022] [Accepted: 05/20/2022] [Indexed: 02/05/2023] Open
Abstract
Several environmental and genetic factors may influence the risk of congenital heart defects (CHDs), which can have a substantial impact on pediatric morbidity and mortality. We investigated the association of polymorphisms in the genes of the folate and methionine pathways with CHDs using different strategies: a case–control, mother–child pair design, and a family-based association study. The polymorphism rs2236225 in the MTHFD1 was confirmed as an important modulator of CHD risk in both, whereas polymorphisms in MTRR, FPGS, and SLC19A1 were identified as risk factors in only one of the models. A strong synergistic effect on the development of CHDs was detected for MTHFD1 polymorphism and a lack of maternal folate supplementation during early pregnancy. A common polymorphism in the MTHFD1 is a genetic risk factor for the development of CHD, especially in the absence of folate supplementation in early pregnancy.

Li M, Wang Y, Zhu W, Zhang C, Fei H. Transthoracic echocardiography features of adult-type anomalous left coronary artery from the pulmonary artery before and after surgery: highlights from observational study in a single center of China. Int J Cardiovasc Imaging 2020; 36:1477-1487. [PMID: 32328871 DOI: 10.1007/s10554-020-01857-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Accepted: 04/18/2020] [Indexed: 02/05/2023]
Abstract
To review the imaging characteristics of adult-type anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) and evaluate the post-operative echocardiographic features. The transthoracic echocardiography (TTE) records and invasive coronary angiography (ICA), coronary computed tomography angiography (CTA) or operative findings of thirty adult patients with final diagnosis of ALCAPA were reviewed at our center. The diagnostic reliability of TTE was determined by comparing its results with that of ICA/CTA, and the echocardiographic features of the patients during early visit and post-operative follow-up were summarized. The coincidence rate of TTE and ICA/CTA diagnosing ALCAPA was 96.3% (26/27), and one case was misdiagnosed as coronary artery fistula. All patients showed abnormal left coronary ostium arising from the pulmonary trunk with retrograde coronary artery flow, 20 patients had enlarged right coronary artery (RCA), and 20 showed abundant inter-coronary septal coronary collaterals. Left ventricle (LV) abnormalities such as wall thinning, abnormal wall motion, papillary muscle fibrosis, mitral valve (MV) prolapse and moderate-severe mitral regurgitation (MR) were respectively observed in 4, 7, 10, 8 and 10 patients. Three patients showed ventricular septal defect, patent foramen ovale and tetralogy of Fallot respectively. Post-operative data was available for 12 patients, and showed that the diameter of RCA, size of left atrium (LA) and LV were decreased after surgery compared to the respective pre-operative values. Furthermore, inter-coronary septal coronary collaterals lessened in 8 of these patients. Although 6 patients showed residual mild MR, moderate or severe MR was not observed, and the ejection fraction (EF) also showed no obvious changes before and after surgery. TTE is a non-invasive diagnostic tool for adult-type ALCAPA, and can indicate abnormal coronary origin, collateral arteries and other associated malformations. Some of the structural and hemodynamic parameters of adult-type ALCAPA were improved after surgery.

Abstract
Pediatric cardiology imaging laboratories in the present day have several modalities for imaging of congenital and acquired cardiovascular disease. These modalities include echocardiography, cardiovascular magnetic resonance imaging, cardiac computed tomography and nuclear imaging. The utility and limitations of multimodal imaging is described herein along with a framework for establishing a cardiology-radiology interface.

J Clin Diagn Res 2016; 10:TE01-10. [PMID: 27630924 DOI: 10.7860/jcdr/2016/21443.8210] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2015] [Accepted: 04/02/2016] [Indexed: 11/24/2022]
Abstract
From the stand point of radiographic analysis most of the complex cyanotic congenital heart diseases (CHD), can be divided into those associated with decreased or increased pulmonary vascularity. Combination of a specific cardiac configuration and status of lung vasculature in a clinical context allows plain film diagnosis to be predicted in some CHD. Correlation of the position of the cardiac apex in relation to the visceral situs is an important information that can be obtained from the plain film. This information helps in gathering information about the atrio-ventricular, ventricular arterial concordance or discordance. Categorization of the cyanotic heart disease based on vascularity is presented below. Thorough understanding of cardiac anatomy by different imaging methods is essential in understanding and interpreting complex cardiac disease. Basic anatomical details and background for interpretation are provided in the previous parts of this presentation.
