In this high-risk cohort of patients, DCB-only angioplasty delivered good clinical outcome at 1 year. The results were comparable with DES-treated patients, but had the added benefit of a shorter DAPT regime.
We evaluated the clinical feasibility of using drug-coated balloon (DCB) angioplasty in patients undergoing primary percutaneous coronary intervention (PPCI). Between January 2010 to September 2014, 89 ST-elevation myocardial infarction patients (83% male, mean age 59 ± 14 years) with a total of 89 coronary lesions were treated with DCB during PPCI. Clinical outcomes are reported at 30 d follow-up. Left anterior descending artery was the most common target vessel for PCI (37%). Twenty-eight percent of the patients had underlying diabetes mellitus. Mean left ventricular ejection fraction was 44% ± 11%. DCB-only PCI was the predominant approach (96%) with the remaining 4% of patients receiving bail-out stenting. Thrombolysis in Myocardial Infarction (TIMI) 3 flow was successfully restored in 98% of patients. An average of 1.2 ± 0.5 DCB were used per patient, with mean DCB diameter of 2.6 ± 0.5 mm and average length of 23.2 ± 10.2 mm. At 30-d follow-up, there were 4 deaths (4.5%). No patients experienced abrupt closure of the infarct-related artery and there was no reported target-lesion failure. Our preliminary experience showed that DCB angioplasty in PPCI was feasible and associated with a high rate of TIMI 3 flow and low 30-d ischaemic event.
BackgroundDrug eluting balloon (DEB) is a new therapeutic option for treatment of obstructive coronary lesions in percutaneous coronary intervention (PCI). There is limited data on the safety and efficacy of DEB in Asian patients in contemporary clinical registries. We evaluated the clinical efficacy and safety of SeQuent Please paclitaxel-eluting balloon in our cohort of South-East Asian patients in real world clinical practice.MethodsBetween January 2010 to November 2012, 320 patients (76% male, mean age 61.3 ± 11.2 years) with a total of 337 coronary lesions were treated with SeQuent Please drug-eluting balloon (DEB). The primary endpoint was major adverse cardiac events (MACE) ie a composite of cardiovascular death, target vessel related myocardial infarction (MI) and target lesion revascularization (TLR) at 9 months follow-up.ResultsThe majority of patients presented with acute coronary syndrome (76%).The most common indication for the use of DEB was small vessel disease (54%) followed by instent restenosis (21%), bifurcation lesions (6%) and others (19%). An average of 1.23 ± 0.5 DEB were used per patient, with mean DEB diameter of 2.6 ± 0.6 mm and average total length of 24.0 ± 11.1 mm.At 9 months follow-up, 5.3% of patients developed MACE. MACE was mainly driven by TLR(4%) followed by target vessel related myocardial infarction (2.6%) and cardiovascular death (1%).ConclusionSeQuent Please DEB was a safe and effective treatment modality in our cohort of South-East Asian patients with a low incidence of MACE observed at 9 months follow-up.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
