Summary
Understanding mitral valve anatomy is crucial for cardiac surgery. This study reveals close proximity between the mitral annulus and coronary arteries, highlighting risks during mitral valve surgery.
Area of Science:
- Cardiovascular Anatomy
- Surgical Anatomy
Background:
- Rheumatic cardiac valve diseases are a significant health concern in Turkey.
- The anatomical relationship between the mitral annulus and coronary arteries is critical in mitral valve surgery.
Purpose of the Study:
- To investigate the correlation between the mitral annulus and coronary arteries.
- To assess the anatomical variations of the mitral annulus in relation to coronary arteries.
Main Methods:
- Analysis of 50 adult human hearts.
- Determination of right/left coronary dominance or codominance.
- Measurement of distances between the mitral annulus and the circumflex coronary artery (CCA) and left posterior descending artery.
Main Results:
- Variations in the proximity of coronary arteries to the mitral annulus were observed.
- In 19 out of 50 cases, coronary arteries were found within 3 mm of the mitral annulus at various points.
Conclusions:
- Damage to the CCA during mitral valve surgery is a risk, particularly in cases of left coronary dominance or codominance.
- Preoperative knowledge of coronary artery anatomy is essential for patient safety in mitral valve surgery.
