Worms can be retrieved from the right atrium, right ventricle and pulmonary arterial apex by using
endoscopic basket, introduced through the jugular vein through a procedure called a jugular venotomy.
It should be noted that if a different extraction device is used (
endoscopic loops and
baskets, rigid or semi-rigid alligator forceps, different types of graspers, etc.), the success rate of the procedure is much lower, at least in our experience.
