Coronary Circulation

2.2K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Summary
This summary is machine-generated.

A thick lateral costal artery (LCA) can cause coronary steal after coronary artery bypass grafting (CABG). Obliterating the LCA resolved angina in a patient, highlighting its importance in preventing postoperative steal.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery

Background:

  • The left internal thoracic artery (LITA) is standard for left anterior descending artery revascularization in coronary artery bypass grafting (CABG).
  • Unsecured lateral costal artery (LCA) branches from the LITA can occur in 10-20% of CABG cases.
  • These unsecured LCAs may lead to postoperative chest angina due to coronary steal.
