Left Heart Catheterization
Direct puncture of the left atrium with a needle, through which a catheter can be passed, allows pressure measurements in atrium, left ventricle and aorta. This procedure is considered to be more helpful than right heart catheterization in evaluation of patients with mitral and aortic valvular lesions.
