“…The authors presented transthoracic echocardiogram and cardiac Magnetic resonance imaging images of a case of midmuscular ventricular septal defect that closed spontaneously by growth of right ventricular trabeculations without obliteration of the defect. 6 Our case confirms that this rare mechanism of spontaneous closure of muscular ventricular septal defect does exist. We provide additional imaging by three-dimensional echocardiography.…”

AbstractWe present a case of an 18-year-old male with large anterior muscular ventricular septal defect. Assessment by echocardiography showed that the defect has completely closed by the growth of muscle bundles that formed a pouch-like structure on the right ventricular side. This unusual mechanism of closure has been reported in one prior case report. In our report, we present images obtained by three-dimensional echocardiography.

“…In the case, fibrotic tissue replaced the defect, but gross examination revealed a small depression on the interventricular septum’s left side [11]. Secondly, Dasgupta S [12] proposed another possible mechanism for closure of muscular VSD: right ventricular endocardial tissue proliferation and coverage. In the report, a 4 mm midmuscular VSD with a left-to-right shunt in a 2-month-old female infant was observed by echocardiography.…”

BackgroundHypertrophic 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 presentationWe 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).ConclusionsTo 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.Electronic supplementary materialThe online version of this article (10.1186/s12872-018-0997-8) contains supplementary material, which is available to authorized users.

Background: Postmortem coronary angiography has been used in forensic medicine for several decades but its use has never been documented in neonatal hearts. The objective of this case is to report the use of postmortem coronary angiography as a diagnostic modality for neonates suspected to have complex congenital heart anomalies. Case presentation: A 36-week-old female infant required extracorporeal membranous oxygenation for persistent hypotension on day 1 of life. A congenital echocardiogram (ECHO) on day 3 of life revealed multiple anomalous vascular structures within the interventricular septum. The infant passed away on day 4 of life after the parents elected to withdraw support. A consent for autopsy was taken from the parents and a postmortem coronary angiography was performed. The coronary vessels were injected with Iodixanol contrast via a 24 G angiocath under fluoroscopy. The anomalous septal vessels were identified as dilated coronary artery and vein. No other anomalies were identified. Conclusion: Postmortem coronary angiography complements other imaging procedures in understanding the nature of some complex congenital heart defects and in determining the cause of death in such neonates.
