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
Mitral regurgitation jet by color Doppler echocardiography. Vena contracta is the narrowest portion of the MR jet at or just beyond the regurgitant orifice. It is an accurate
Aortic flow velocity by Doppler echo is routinely measured and is useful to assess aortic gradient in aortic stenosis. It is also useful in calculating valve area by
Right coronary angiogram showing conus branch, sinus node artery, right ventricular branches, posterior descending coronary artery and the stump of posterior left ventricular branch.
