Slide 1: WESLEYAN UNIVERSITY – PHILIPPINES CABAN ATUAN CITY COLLEGE OF NURSING
Slide 2: ANGIOPLASTY VS. BYPASS SURGERY
Slide 3: ANATOMY AND PHYSIOLOGY
Slide 5: ANGIOPLASTY
Slide 6: •Percutaneous coronary intervention (PCI). or •Percutaneous Transluminal Coronary Angioplasty
Slide 7: ATHEROSCLEROSIS
Slide 8: Cardiac catheterization
Slide 9: Why It Is Done •Frequent or severe chest pain (angina) that is not responding to medication. •Evidence of severely reduced blood flow (ischemia) to an area of heart muscle caused by one or more narrowed coronary arteries. •An artery that is likely to be treated successfully with angioplasty whether or not stenting is also used. •You are in good enough health to undergo the procedure
Slide 10: STENTS A small, expandable wire tube is often permanently inserted into the artery during angioplasty. •Balloon angioplasty
Slide 11: Stenting should: •Open up the artery and press the plaque against the artery's walls, thereby improving blood flow. •Keep the artery open after the balloon is deflated and removed. •Seal any tears in the artery wall.
Slide 12: •Prevent the artery wall from collapsing or closing off again (restenosis). •Prevent small pieces of plaque from breaking off, which might cause a heart attack.
Slide 13: Coronary angioplasty: Blockage in a coronary artery
Slide 14: Coronary angioplasty: Step 1
Slide 15: Coronary angioplasty: Step 2
Slide 16: Coronary angioplasty: Step 3
Slide 17: Coronary angioplasty: Final
Slide 19: How Well It Works Angioplasty relieves chest pain and improves blood flow to the heart. If restenosis occurs, another angioplasty or bypass surgery may be needed.
Slide 20: Stents: •Coated stents •Intracoronary radiotherapy •Rotational atherectomy
Slide 22: RISKS: •Bleeding at the puncture site. •Sudden closure of the artery. •Heart attack. •Need for additional procedures. Angioplasty may increase the risk of needing urgent bypass surgery. In addition, the repaired artery can renarrow (restenosis) and a repeat angioplasty may need to be performed.
Slide 23: •Reclosure of the grafted blood vessel (restenosis). •Death. The risk of death is higher when more than one artery is involved.
Slide 25: BYPASS
Slide 26: CABG- coronary artery bypass graft -To improve the blood flow to the myocardial tissue
Slide 28: How is coronary bypass done? Surgeons take a segment of a healthy blood vessel from another part of the body and make a detour around the blocked part of the coronary artery. •An artery may be detached from the chest wall and the open end attached to the coronary artery below the blocked area.
Slide 29: •A piece of a long vein in your leg may be taken. One end is sewn onto the large artery leaving your heart -- the aorta. The other end of the vein is attached or \"grafted\" to the coronary artery below the blocked area. •Either way, blood can use this new path to flow freely to the heart muscle.
Slide 33: NURSING CARE: •PRE-OP CARE •INTRA-OP CARE •POST-OP CARE
