TCTAP C-288 Drug-coated Balloon Angioplasty for Proximal Left Anterior Descending Artery Lesion: Lumen Enlargement and Plaque Modification After 5 Months Follow-up

Relevant test results prior to catheterization WBC count (normal), Hemoglobin (normal), Platelet count (normal), CK-MB(-), Myoglobin (-), High-sensitivity troponin I (-), BNP (-), Total protein (normal), Albumin, TG (6.5 mmol/L), TC (normal), HDL (normal), LDL (2.1mmol/L), Baseline electrocardiogram (ECG)showed no significance ST-segment elevation or depression (Figure.1). Dual platelet inhibition (DAPT),aspirin (100 mg/qd) plus second anti-platelet agent (ticagrelor 90 mg/bid);Anti-coagulant (heparin, administered in catheter lab for primary percutaneous coronary intervention, PPCI); Oral beta blockers (metoprolol23.75 mg/qd); ARB (valsartan 80mg/qd); statins (atorvastatin mg/qn). The patient and family refused to stent implantation and coronary artery bypass grafting (CABG); so we opted for a total-drug coated balloon (DCB) angioplasty without stent implantation. Run through guid wire was inserted through the guiding catheter and positioned in distal LAD. Since the patient was refused to stent implantation and CABG, we opted for a total-drug coated balloon (DCB) angioplasty. In order to achieve optimal apposition, we plan to prefer the quantitative angiography with optical coherence tomography (OCT) or intravascular ultrasounds (IVUS), but the patient and family refused to do IVUS and OCT. [...]there is no IVUS and OCT image. Case Summary Drug-coated balloon (DCB) has emerged as an novel device for percutaneous coronary intervention (PCI), which has...
