IPCCC ICD-11 Congenital Heart Atlas

You are here: Left ventricular myocardial sinusoids Congenital left ventricular anomaly Congenital anomaly of a ventricle or the ventricular septum Structural developmental anomaly of heart or great vessels

IPCCC Term Left ventricular myocardial sinusoids
IPCCC Code 07.06.12
ICD-11 Code 1635129695


A congenital cardiac malformation in which there are deep, endothelial lined, blind-ended intramyocardial tunnels communicating with the left ventricular chamber. These occur in the setting of aortic atresia or severe left ventricular outflow tract obstruction, intact ventricular septum and a patent mitral valve.



STS-EACTS-derived IPCCC term

LV abnormality, LV myocardial sinusoids

EPCC-derived IPCCC term

Left ventricular myocardial sinusoids

ICD-11 MMS code or crossmap

LA88.Y*: This Foundation term is not in ICD-11 MMS. If coding in MMS use term “Other specified congenital anomaly of a ventricle or the ventricular septum” with code LA88.Y

ICD-10 MMS code or crossmap

Q24.8**: This Foundation term is not in ICD-10. If using ICD-10, code with higher order term “Other specified congenital malformations of heart” with code Q24.8


Congenital left ventricular anomaly


Coding Notes

Where connections from the left ventricle to the coronary arteries exist, one should code for "Congenital coronary arterial fistula to the left ventricle" with the IPCCC number 09.45.22, or crossmap to the the ICD-11 MMS term "Congenital coronary arterial fistula" with code LA8C.2. This Foundation term should not be used for left ventricular non-compaction.
