Anomalous origin of the left coronary artery from pulmonary artery mimicking antero-lateral ST-elevation myocardial infarction: a case report.

Cardiology Department, Meir Medical Center, Tchernichovsky St 59, Kfar Saba 4418001, Israel.
Background: Anomalous origin of the left coronary artery (LCA) from the pulmonary artery (PA) (ALCAPA) is a rare congenital abnormality. We present a case of an ALCAPA in a 25-year-old man.
Case Summary: A 25-year-old male with no past medical history was admitted to our intensive cardiac care unit after sudden cardiac arrest due to ventricular fibrillation and suspected acute coronary syndrome.

We present the case of a 73-year-old woman with coronary artery-left ventricular multiple microfistulae, who was admitted with symptoms and ECG suggestive of coronary artery disease. Coronary angiography revealed tortuous coronary arteries with multiple microfistulae between the left coronary artery and the left ventricle, as well as between the right coronary artery and the left ventricle. Transthoracic echocardiography (TTE) was also able to clearly demonstrate the presence of the microfistulae with their direction of blood flow towards the left ventricle.

Background: Coronary anomalies are those conditions characterized by the abnormal origin or course of the epicardial arteries. This generates challenges at the time of diagnosis by catheterization, which is why it is important that the cardiologist is related to these variations. The origin of the left coronary artery in the right sinus of Valsalva has a low incidence.

The adult mammalian heart is known to have very limited regenerative capacity, explaining at least in part the frequency of cardiovascular diseases and their impact as the leading cause of death worldwide. By contrast, the neonatal heart has the ability to regenerate upon injury, and the molecular mechanisms underlying this regenerative capacity are intensely investigated to provide novel cues for the repair of the adult heart. However, the existing rodent neonatal injury models-apex resection, left anterior descending artery ligation and cryoinjury-have limitations, such as being technically demanding, yielding a nonphysiological injury type and/or lack of reproducibility.

Article Synopsis
- Myocardial infarction in children is rare but can occur unexpectedly, often leading to severe outcomes if not treated quickly.
- A study of 18 pediatric cases revealed varied causes of myocardial infarction, primarily related to congenital coronary issues, with a significant number of cases in infants under one year old.
- The overall mortality rate was 33%, with poor transplant-free survival, emphasizing the need for early diagnosis and intervention to improve outcomes.
