title: Percutaneous Ventricular Restoration Therapy Using the Parachute Device in Chinese Patients with Ischemic Heart Failure: Three-Month Primary End-point Results of PARACHUTE China Study.
abstract: BACKGROUND
  The primary cause of ischemic heart failure (HF) is myocardial infarction (MI) resulting in left ventricle (LV) wall motion abnormality secondary to ventricular remodeling. A prospective, nonrandomized study conducted in China was designed to assess safety and efficacy of the percutaneous ventricular restoration therapy using Parachute device (CardioKinetix, Inc., CA, USA) in ischemic HF patients as a result of LV remodeling after anterior wall MI.
  
  
  METHODS
  Thirty-one patients with New York Heart Association (NYHA) Class II, III ischemic HF, ejection fraction between 15% and 40%, and dilated akinetic or dyskinetic anterior-apical wall without the need to be revascularized were enrolled from seven sites in China from October to December 2014. The Parachute device was implanted through femoral artery. All patients received low-dose aspirin and anticoagulation with warfarin for at least 12 months postdevice implantation. The primary end-point was the assessment of efficacy as measured by the reduction in LV end-systolic volume index (LVESVI) against baseline LVESVI at 3 months postdevice implantation, determined by the echocardiography and measured by echocardiography core laboratory. Quality of life was assessed using EQ-5D and visual analog scale (VAS). For quantitative data comparison, paired t-test (normality data) and signed-rank test (abnormality data) were used; application of signed-rank test was for the ranked data comparison.
  
  
  RESULTS
  A change in LVESVI as measured by echocardiography from the preimplant baseline to 3-month postdevice implantation revealed a statistically significant reduction from 77.5 ± 20.0 ml/m2 to 53.1 ± 17.0 ml/m2 (P < 0.0001). The trial met its primary end-point. Of the 31 patients, the procedural success was 96.8%. Overall, NYHA HF class assessment results showed an improvement of more than half a class at 3 months (P < 0.001). Quality of life assessed by the VAS value increased 11.5 points (P < 0.01), demonstrating improvement at 3 months.
  
  
  CONCLUSIONS
  The favorable outcomes observed in the high-risk patients provide reassuring safety and efficacy data to support adoption of this technology as a therapeutic option for ischemic HF patients.
