Abstract
A method for performing cardiology and endovascular interventional operations includes: Step 1, putting an artery sheath into a punctured artery; inserting a Pigtail catheter into a first end of the artery sheath, and advancing it to a left ventricle; injecting contrast into the Pigtail catheter to perform left ventricle angiography; and withdrawing the Pigtail catheter from the artery sheath. Step 2, inserting a guiding catheter into the first end of the artery sheath, and advancing it to the left ventricle. Step 3, advancing a myocardial biopsy forcep to a left ventricle endocardium through the guiding catheter to collect a piece of myocardium. Step 4, withdrawing the myocardial biopsy forcep from the guiding catheter, and preserving a myocardium specimen. Step 5, repeating steps 3 and 4 until collecting enough number of myocardium specimens. Step 6, withdrawing the guiding catheter from the artery sheath, and pulling the artery sheath out of the artery.
