Key result
An isolated hypoplastic left circumflex coronary artery was identified as the cause of a fatal haemorrhagic myocardial infarction in a 16-year-old athlete following sudden cardiac arrest.
Case Report (n=1)
No
This case report provides the first description of an isolated hypoplasia of the left circumflex artery leading to haemorrhagic myocardial infarction and sudden cardiac death in a young athlete.
Consider isolated LCx hypoplasia in young athlete SCD; leaves open prevalence and screening value.
Hypoplastic coronary artery disease is a rare condition that may lead to myocardial infarction and sudden death. Here we describe for the first time an isolated hypoplasia of the left circumflex artery (LCX). An otherwise healthy and athletically active 16-year-old boy was admitted to the intensive care unit (ICU) after out-of-hospital cardiac arrest. He died 12 hours after the initial event. Autopsy revealed an isolated hypoplastic LCX and acute haemorrhagic infarction in the posterolateral myocardium. The existence of isolated hypoplasia of the LCX challenges our understanding of coronary artery development.
