CAD, vessel coronary lesions
CORONARY ARTERY DISEASE, CAD
Patients with coronary artery disease (CAD) have three common therapeutic options: (1) medical therapy and risk factor modification, (2) coronary artery bypass graft surgery (CABG) and (3) percutaneous coronary intervention (PCI). As PCI technology and revascularization procedures evolved, balloon angioplasty, bare metal stent (BMS) and drug-eluting stent (DES) succeeded each other as the primary catheter-based treatment for CAD. Recent evidence indicates that drug-coated balloons (DCBs) can also be safely used for the treatment of small vessel coronary lesions [Drug delivery via DCB could result in a more homogeneous administration of the drug instead of creating a peri-strut gradient [Agent uses the Emerge™ percutaneous transluminal coronary angioplasty (PTCA) balloon catheter platform (Boston Scientific Corporation) with a reduced paclitaxel dose density (2 μg/mm
