Abstract
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.
Highlights
Hypertrophic cardiomyopathy (HCM) is a myocardial disease
The systolic blood flow signals representing a muscular ventricular septal defect (VSD) have been identified within the hypertrophic ventricular septum, which was different from a coronary artery-left ventricular fistulae characterized by diastolic blood flow signals [6]
Following contrast-enhanced echocardiography, the unique small defect, i.e., the interlink with the left ventricular cavity, but not the right ventricular cavity, is very different from most of the small muscular VSDs that can close spontaneously within the first two years of life [7], suggesting that some unknown factors may be involved in the process of incomplete spontaneous closure of muscular VSD
Summary
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 missed if examined by the single echocardiography. HCMassociated congenital abnormalities should be screened by combination of transthoracic 2D, color Doppler, contrastenhanced echocardiography, and CTA
