Treating Clogged Arteries

Dissolving Blod Clots

In a heart transplant procedure, a surgeon removes the diseased heart and sews the donor heart in place. He or she then attaches the major blood vessels to the donor heart.

The heart doctor (cardiologist) guides a thin, flexible tube (catheter) to the narrowed part of the heart artery. A tiny balloon is inflated to help widen the blocked artery and improve blood flow. A small wire mesh tube (stent) may be placed in the artery during angioplasty

Thrombolytics - medicine that dissolves blood clots. Catheter-directed thrombolysis - a procedure in which a long tube, called a catheter, is surgically inserted and directed toward the blood clot where it delivers clot-dissolving medication
