Risk of Mortality with Paclitaxel Drug-Coated Balloon in De Novo Coronary Artery Disease

摘要

A recent meta-analysis showed increased mortality with paclitaxel drug-coated balloons (PCB) in peripheral arterial disease. With the absence of a definitive study evaluating the risk of mortality with PCB in de novo coronary artery disease, we performed a systematic review and critical appraisal of the literature analyzing this risk. In this review, we included 17 trials with a total of 1573 patients. Cardiac mortality was reported in 16 studies and all-cause mortality in 14 studies. Eleven studies had = 12 months' follow-up. None of the studies was powered to evaluate any differences in mortality. The majority of the included studies have a Jadad scale <= 2. Ten of 17 studies had no mortality, 4 had numerically higher mortality with PCB, and 3 had lower or same mortality with PCB, when compared to drug-eluting stents. A standard meta-analysis cannot be performed, as most studies did not report hazard ratios or Kaplan-Meier survival plots on mortality. With the available literature, conclusions cannot be made in identifying the association of mortality with PCB in de novo coronary artery disease. There is an urgent need for well-designed studies with long-term follow-up for PCB in de novo coronary artery disease.
