PHTY300 Lecture Notes - Lecture 11: Median Sternotomy, Pulmonary Hypertension, Coronary Artery Bypass Surgery
Document Summary
Covers all diseases and conditions of the heart and blood vessels. Acute coronary syndrome (acs) - includes mis & angina. Pathophysiology = endothelial dysfunction, vascular inflammation and abnormal deposits of fat, cholesterol and other substances in the inner lining of the coronary arteries to form plaques. Leads to reduced or blocked blood supply (ischaemia or infarction) to myocardium. Symptoms = angina, arrhythmias, collapse or cardiac arrest. Cabg valve surgery (avr, mvr, tvr, pvr) Via median sternotomy (post-operative sternal precautions: coronary artery bypass grafting (cabg, valve replacement or repair. Diagnostic angiography (with dye) to identify blockages +/- balloon plasty or insertion of stent.
