Article Synopsis
- Coronary artery anomalies (CAA) are congenital heart conditions that can cause serious issues like arrhythmias and sudden cardiac death due to abnormal coronary artery structure and function.
- A 58-year-old woman experienced chest pain and shortness of breath, leading to the discovery of a rare coronary artery anomaly during cardiac catheterization, including an unusual left anterior descending artery and an absent left circumflex artery.
- Despite being treated with various medications for her condition, she continued to suffer from chronic angina, and a surgical assessment determined that her arterial anomaly was not operable.
Background: Patients undergoing percutaneous coronary intervention (PCI) who are at high risk for cardiovascular collapse during the procedure may benefit from prophylactic circulatory support. The objective was to evaluate the safety and feasibility of prophylactic use of the Impella 2.5 during high-risk PCI.

- A study involving 2,465 patients examined the link between mitral annular calcium (MAC) severity and coronary artery narrowing, revealing that patients with severe MAC had a higher prevalence of significant narrowing in their coronary arteries.
- Patients with severe MAC had an 82% incidence of over 70% narrowing in major coronary arteries, while those with moderate/mild MAC had 79%, and those with no MAC had 69%.
- The findings suggest that the presence of MAC is strongly associated with both one-vessel and three-vessel coronary artery disease, indicating a need for careful evaluation in patients with this condition.
Coronary artery anomalies have an incidence of 0.6% to 1.3% in angiographic studies and 0.

Methods: We analyzed data from 105 consecutive patients who presented with chest pain to an emergency department and who were hospitalized in an inpatient telemetry unit but who were at low risk for a coronary event.
Results: Telemetry yielded no information which was used to manage any patient.
Percutaneous transluminal coronary angioplasty (PTCA) was performed in all 1,050 patients hospitalized within 24 hours of symptoms of documented acute myocardial infarction (AMI) from 1998 to 2002. Hospital mortality was similar in women and men who underwent PTCA for AMI but was higher in patients aged 75 to 95 years (10%) than in patients aged 21 to 50 (2.1%, p <0.
