Chambers of the Heart

12.3K
The human heart is a complex organ made up of four chambers: the right and left atria and the right and left ventricles. These internal chambers are separated by partitions known as the interatrial and interventricular septa. The exterior of the heart features a groove known as the coronary sulcus that demarcates the atria from the ventricles, while the anterior and posterior interventricular sulci distinguish between the two ventricles.

Area of Science:

  • Cardiology
  • Cardiac Imaging
  • Electrophysiology

Background:

  • Atrial fibrillation (AF) is a common arrhythmia, increasing with age.
  • Thrombus formation in the left atrial appendage (LAA) is frequent in AF patients, posing a risk for cardioembolic events.
  • Assessing LAA thrombi is critical for AF management, especially before cardioversion and for transcatheter therapies.

Purpose of the Study:

  • To review current data on left atrial appendage (LAA) anatomy, function, and imaging.
  • To highlight the importance of LAA evaluation in patients with atrial fibrillation (AF).
  • To discuss optimal noninvasive imaging techniques for LAA thrombus detection.

Main Methods:

  • Review of current scientific literature and data.
  • Analysis of noninvasive imaging modalities for LAA assessment.
  • Synthesis of information on LAA anatomy and function in the context of AF.

Main Results:

  • The LAA is a common site for thrombus formation in AF due to stasis and reduced contractility.
  • Accurate LAA imaging is essential for risk stratification and guiding treatment decisions in AF.
  • Various noninvasive imaging techniques are available for evaluating LAA morphology and function.

Conclusions:

  • Understanding LAA anatomy and function is critical for managing AF-related cardioembolic risk.
  • Optimal imaging techniques are necessary to identify or exclude LAA thrombi in AF patients.
  • LAA evaluation is integral to current and emerging transcatheter therapies for AF.
