(2) Mitral regurgitation ⚫ Causes: pathology of the mitral leaflets, subvalvular mechanism (chordae or papillary muscles) or mitral annulus. ⚫ The haemodynamic consequence of mitral regurgitation is systolic increase in left atrial pressure and pulmonary venous pressure during systole. ⚫ Plain radiography shows various degrees of pulmonary venous hypertension and cardiomegaly. The severity of pulmonary venous hypertension is generally less than in predominant mitral stenosis. Cardiomegaly is a consequence of left atrial and left ventricular enlargement. 15’ 15’ 15’ 10’

2 Coronary Heart Disease (1) coronary arteries anatomy ⚫ The left coronary artery usually divides into the left anterior descending (LAD) and circumflex (Cx) arteries. ⚫ The right coronary artery (RCA) courses in the right atrioventricular groove. (2) Technique ⚫ Coronary angiography ⚫ Coronary CT angiography ⚫ Coronary MR angiography (3) Coronary artery spasm ⚫ Coronary artery spasm is dynamic narrowing of the coronary causing reduction of blood flow and angina pectoris. ⚫ Coronary arteriography reveals a coronary arterial stenosis or occlusion which spontaneously resolves or is alleviated by nitroglycerin and other vasodilators. 15’ 10’ 20’
