LA85

ICD-11 MMS 2026-01

Congenital anomaly of an atrioventricular or ventriculo-arterial connection

Description

A congenital cardiovascular malformation in which one or more of the following connections is abnormal 1) the morphologically right atrium to the morphologically right ventricle, 2) the morphologically left atrium to the morphologically left ventricle, 3) the morphologically right ventricle to the pulmonary trunk, 4) the morphologically left ventricle to the aorta. This excludes codes for hearts with a univentricular atrioventricular connection (mitral atresia, tricuspid atresia and double inlet ventricle), as these are listed under Functionally Univentricular Heart.

Excludes

  • LA89 – Functionally univentricular heart

Exclusions from above levels

  • http://id.who.int/icd/entity/733825440 – Inborn errors of metabolism

Child codes

  • LA85.0 – Discordant atrioventricular connections
  • LA85.1 – Transposition of the great arteries
  • LA85.2 – Double outlet right ventricle
  • LA85.3 – Double outlet left ventricle
  • LA85.4 – Common arterial trunk
  • LA85.Y – Other specified congenital anomaly of an atrioventricular or ventriculo-arterial connection
  • LA85.Z – Congenital anomaly of an atrioventricular or ventriculo-arterial connection, unspecified

Sibling codes

  • LA80 – Anomalous position-orientation of heart
  • LA81 – Abnormal ventricular relationships
  • LA82 – Total mirror imagery
  • LA83 – Right isomerism
  • LA84 – Left isomerism
  • LA86 – Congenital anomaly of mediastinal vein
  • LA87 – Congenital anomaly of an atrioventricular valve or atrioventricular septum
  • LA88 – Congenital anomaly of a ventricle or the ventricular septum
  • LA89 – Functionally univentricular heart
  • LA8A – Congenital anomaly of a ventriculo-arterial valve or adjacent regions
  • LA8B – Congenital anomaly of great arteries including arterial duct
  • LA8C – Congenital anomaly of coronary artery
  • LA8D – Congenital pericardial anomaly
  • LA8E – Congenital anomaly of atrial septum
  • LA8F – Congenital anomaly of right atrium
  • LA8G – Congenital anomaly of left atrium
  • LA8Y – Other specified structural developmental anomaly of heart or great vessels
  • LA8Z – Structural developmental anomaly of heart or great vessels, unspecified
