left heart catheterization
Invasive procedure to evaluate left-sided cardiac pressures, coronary anatomy, and left ventricular function.
Full Definition
Left heart catheterization is an invasive diagnostic procedure that involves advancing catheters retrograde through the arterial system to assess the left ventricle and coronary arteries. The procedure typically includes measurement of left ventricular pressures, assessment of mitral and aortic valve function, left ventriculography to evaluate wall motion and ejection fraction, and selective coronary angiography. Access is commonly obtained via the radial or femoral artery using the Seldinger technique. Left heart catheterization provides definitive anatomical and hemodynamic information essential for diagnosing coronary artery disease, valvular abnormalities, and cardiomyopathies. The procedure is often performed in conjunction with right heart catheterization for complete hemodynamic assessment.
Usage
Usage note: Hyphenate 'left-heart' when used as a compound modifier.
