Left main coronary artery aneurysm

Aneurysma der A. coronaria sinistra

Abstract

Left main coronary artery aneurysms (LMCA) are usually asymptomatic and are rarely encountered during coronary angiography. The most serious complications include coronary thrombosis, acute myocardial infarction and sudden death. Atherosclerosis is the most common cause, although several autoimmune diseases and congenital abnormalities have been associated with the presence of coronary aneurysms. The case of a symptom-free 63-year-old man with a giant LMCA and severely ectatic coronary arteries is presented.

Zusammenfassung

Aneurysmata der A. coronaria sinistra („left main coronary artery aneurysms“, LMCA) verursachen in der Regel keine Symptome und werden bei der Koronarangiographie nur selten gesehen. Zu den wesentlichen Komplikationen zählen Koronarthrombose, akuter Myokardinfarkt und plötzlicher Herztod. Am häufigsten ist ein Aneurysma atherosklerotisch bedingt, doch es tritt auf in Verbindung mit Autoimmunerkrankungen und angeborenen Fehlbildungen auch. Es wird der Fall eines 63-jährigen symptomfreien Patienten mit ausgedehntem LMCA und deutlich ektatischen Koronararterien vorgestellt.
