What does a left heart catheterization assess?

Left heart catheterization is a diagnostic procedure that primarily evaluates the left side of the heart, specifically assessing the coronary arteries, cardiac chambers (particularly the left atrium and left ventricle), and valve function. This procedure is instrumental in visualizing the coronary arteries to detect any obstruction due to atherosclerosis or other conditions. When blockages or significant narrowing are identified, this assessment often informs decisions regarding the necessity for surgical interventions, such as angioplasty or coronary artery bypass grafting.

The focus on coronary artery obstruction and the need for surgical interventions highlights the role of left heart catheterization in the management of coronary artery disease, which is a common cause of heart failure and other severe cardiac events. Understanding this aspect is crucial for nursing professionals dealing with patients at risk for or diagnosing heart complications.
