Published: August 2024

Anomalous origin of the circumflex artery from the pulmonary artery (ACxAPA) is a rare but clinically significant condition in which the circumflex artery arises from either the main pulmonary artery or one of its main branches. Untreated patients with ACxAPA may develop severe heart failure or sudden cardiac death. Diagnosis is established with either catheter or CT angiography. We present a case of an adult male with no prior known cardiac history who was found to have ACxAPA after presenting to our institution in acute decompensated heart failure.

: ST-segment elevation myocardial infarction (STEMI) remains a leading cause of mortality worldwide, primarily caused by acute thrombosis over atherosclerotic plaques. Simultaneous acute thrombosis in two coronary arteries is an exceptionally rare event. This report highlights a unique case of STEMI associated with cardiogenic shock due to dual coronary artery thrombosis and provides insights from a literature review on this rare condition.

Patients with anomalous coronary artery origins (AOCA) exhibit a higher risk of atherosclerosis, where even minimal stenosis may lead to adverse cardiovascular events. However, the factors contributing to this heightened risk in AOCA patients remain unclear. This study aimed to investigate whether an AOCA patient is more prone to stenosis occurrence and its progression in view of hemodynamics.

Coronary artery ectasia (CAE) is an abnormal dilatation of coronary artery segments, often linked with atherosclerosis. This report discusses two cases of CAE presenting as acute coronary syndrome. A 36-year-old man had proximal blockage in the left circumflex artery (LCx) and ectasia in the obtuse marginal artery and left anterior descending artery (LAD), while a 53-year-old male smoker had an ectatic LAD with a substantial thrombus.

Article Synopsis
  • Coronary artery ectasia (CAE) is a rare condition usually found during coronary angiography and can increase the risk of blood clots.
  • A 40-year-old male with acute coronary syndrome experienced a complete blockage in his ectatic left circumflex artery and the dominant right coronary artery.
  • After thrombus aspiration restored normal blood flow, the case highlights the difficulties in treating acute coronary syndrome in patients with CAE and stresses the need for further research on effective treatment methods.

Assessing myocardial viability is crucial for managing ischemic heart disease. While late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is the gold standard for viability evaluation, it has limitations, including contraindications in patients with renal dysfunction and lengthy scan times. This study investigates the potential of non-contrast CMR techniques-feature tracking strain analysis and T1/T2 mapping-combined with machine learning (ML) models, as an alternative to LGE-CMR for myocardial viability assessment.
