ORPHA:99130Morphological anomaly
What it is
Congenital partial agenesis of pericardium is a rare, mostly asymptomatic, congenital heart malformation mainly characterized by the partial absence of the left pericardium. It is occasionally associated with chest pain or dyspnea and is usually incidentally diagnosed during surgery or at autopsy. Herniation and strangulation of a portion of the heart through the pericardial foramen may occur, resulting in myocardial acute ischemia and possible sudden death. Right side pericardium involvement is rare.

Orphanet records these for the broader condition rather than for this specific form. They are a starting point, not a figure for this subtype — subtypes often differ, and some are defined by being rarer than the condition they sit under.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
