Brief Answer:
Investigation and management for blocked coronary arteries

Detailed Answer:
Hi friend
Welcome to Health Care Magic

      Angiogram is an investigation. A small catheter is introduced from a peripheral artery into the coronary artery (blood vessel of the heart). Small amounts of contrast (dye) are injected and the vessel is visualised in several angles. It will detect blocks – its presence, location, extent, its severity and feasibility of intervention. Subsequently, the catheter is introduced into the left ventricle (lower heart chamber) and its function is assessed – wall motion, ejection fraction, pressure, saturation are all documented. It is the only way to directly ‘see’ the block / it is the gold standard against which all other investigations are compared.
     The aim of any investigation is to modify the treatment, based on the result. Intervention – dilatation of the narrowing with balloon at the tip of a catheter to widen it and placing a stent (Angioplasty) – is done at or after the procedure – to ensure patency of the vessel. If it is not technically feasible, a CABG may be necessary (Surgery - Coronary Artery Bypass Graft).

Good luck
God bless you
