Bridging collaterals on coronary angiogram Bridging collaterals are a feature of chronic total coronary occlusions (CTO). They bridge between the proximal and distal parts of a coronary artery
Proximal right coronary artery stenosis Right coronary angiogram in LAO (left anterior oblique) cranial view shows proximal luminal irregularities with narrowest segment near the origin of a right
Spider view – LAO caudal view – coronary angiogram Spider view – LAO (left anterior oblique) caudal view is often the first view taken during diagnostic coronary angiography.
Stenosis of left circumflex and major obtuse marginal coronary arteries Coronary angiograms in RAO caudal and AP caudal views, showing stenosis of left circumflex and major obtuse marginal
Left anterior descending coronary artery stenosis Stenosis of mid segment of left anterior descending (LAD) coronary artery seen on anteroposterior (AP) cranial view just after diagonal branch. Distal
LV aneurysm seen on left ventriculogram and near total occlusion of the left anterior descending coronary artery (LAD), which is poorly collateralized.
Serial angiographic shots showing steps in device closure of patent ductus arteriosus (PDA). Though small PDAs can be closed by coil occlusion, larger ones require device closure.
Balloon aortic valvotomy (BAV) is usually done through the transfemoral route. Potential risks include balloon rupture and embolisation of calcific material, apart from access site issues.
Percutaneous transluminal coronary angioplasty (PTCA) Here is an illustrated review of steps in percutaneous transluminal coronary angioplasty (PTCA) of left anterior descending (LAD) coronary artery: Balloon inflation in
