Coronary Angiography & Stenting

If significant coronary artery disease is suspected coronary angiography may be arranged. This is performed in hospital.

Angiography involves the advancement of a catheter under radiological guidance via an arterial puncture, typically the radial artery (wrist). Once the coronary arteries are imaged using contrast, further intracoronary assessment may include imaging with ultrasound (IVUS), light waves (OCT) or pressure wire testing (FFR) prior to determining the appropriate treatment option . The options for treatment are dependent upon your clinical situation and coronary anatomy, but include medical therapy, coronary stenting or heart bypass surgery.

Coronary stenting involves the passage of a fine wire through and beyond the blockage or narrowing in the coronary artery, then opening up the blockage with a balloon (angioplasty) and placement of an internal arterial scaffold (stent). In complex cases of coronary arterial calcification where the calcium prevents balloon dilatation of a severe coronary narrowing, a diamond drill (rotational atherectomy) or shockwave (lithotripsy) may be required prior to successful balloon dilatation and stent deployment.

Discharge from hospital is usually the same day if only coronary angiography is performed and the next morning if coronary stenting is performed. Please remember you should not drive home from hospital after either procedure.
