Inflation of PTCA (percutaneous transluminal coronary angioplasty) balloon positioned across the stenosis of obtuse marginal (OM) branch of the left circumflex coronary artery. This step was the final step in angioplasty in yester years, but now most of the lesions are stented with either a bare metal stent (BMS) or a drug eluting stent (DES). Stenting reduces the chances of acute and subacute vessel closures and also stabilizes dissections if any.
