Cardiac<unk>  refers to the insertion of hollow tubes (catheters) into various structures of the<unk> .  When catheters are inserted specifically into the<unk>  ventricle, the procedure is called<unk><unk><unk> .  This procedure is to be distinguished from coronary<unk>  in which catheters are inserted specifically into the coronary arteries.  Important internal<unk>  and lung blood pressures, not measurable from outside the body, can be accurately measured during the test. <unk><unk><unk>  involves insertion of catheters into the<unk>  ventricle to interrogate that filling pressures of the<unk><unk> . <unk><unk>  catehterization is used to diagnose and assess the severity of aortic stenosis, aortic insufficiency, hypertrophic obstructive cardiomyopathy, mitral stenosis, and mitral insufficiency.
