Abstract
Coronary Artery Fistulae (CAFs) are cardiac congenital anomalies consisting of an abnormal communication of a coronary artery with either a cardiac chamber or another cardiac vessel. In humans, these congenital anomalies can lead to complications such as myocardial hypertrophy, endocarditis, heart dilatation, and failure. Unfortunately, despite their clinical relevance, the aetiology of CAFs remains unknown. In this work, we have used two different species (mouse and avian embryos) to experimentally model CAFs morphogenesis. Both conditional Itga4 (alpha 4 integrin) epicardial deletion in mice and cryocauterisation of chick embryonic hearts disrupted epicardial development and ventricular wall growth, two essential events in coronary embryogenesis. Our results suggest that myocardial discontinuities in the embryonic ventricular wall promote the early contact of the endocardium with epicardial-derived coronary progenitors at the cardiac surface, leading to ventricular endocardial extrusion, precocious differentiation of coronary smooth muscle cells, and the formation of pouch-like aberrant coronary-like structures in direct connection with the ventricular lumen. The structure of these CAF-like anomalies was compared with histopathological data from a human CAF. Our results provide relevant information for the early diagnosis of these congenital anomalies and the molecular mechanisms that regulate their embryogenesis.

A case of hypertrophic cardiomyopathy combined with muscular ventricular septal defect and abnormal origin of right coronary artery. BMC Cardiovasc Disord 2019; 19:16. [PMID: 30642255 PMCID: PMC6332565 DOI: 10.1186/s12872-018-0997-8] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2018] [Accepted: 12/27/2018] [Indexed: 11/10/2022] Open
Abstract
Background Hypertrophic cardiomyopathy (HCM) is a myocardial disease. However, the coexistence of HCM with muscular ventricular septal defect (VSD), especially those with both incomplete spontaneous closure and coronary abnormal origin, is relatively rare. Case presentation We report herein a unique case of HCM accompanied with incomplete spontaneous closure of muscular VSD and abnormal origin of right coronary artery (RCA) in a 26-year-old man, which was diagnosed by combination of transthoracic 2-dimensional (2D), color Doppler, Contrast-enhanced echocardiography and computed tomography angiography (CTA). Conclusions To our knowledge, this is the first report that HCM along with the incomplete spontaneous closure of muscular VSD and anomalous RCA arising from left coronary sinus was revealed through combination of transthoracic 2D, color Doppler, Contrast-enhanced echocardiography and CTA. These observations indicated that other associated anomalies in patients with HCM could be easily missed if examined by the single echocardiography. Therefore, HCM-associated congenital abnormalities should be screened by combination of transthoracic 2D, color Doppler, contrast-enhanced echocardiography, and CTA.
