JOURNEY LVAD: JOURNEY Left Ventricular Assist Device

Официальное название

Transcatheter Therapy to Treat Aortic Regurgitation in the Presence of a Left Ventricular Assist Device

Обзор

The objective of this study is to assess the safety and effectiveness of the J-Valve Transfemoral Transcatheter Heart Valve System in patients on left ventricular assist device (LVAD) support with significant native aortic valve regurgitation (AR).

Вмешательства

• Устройство J-Valve Transfemoral System
  Treatment includes using the J-Valve Transfemoral (TF) System, a transcatheter aortic valve replacement system that consists of the J-Valve TF Bioprosthesis and the J-Valve TF Delivery Device and Loading Accessories, during transcatheter aortic valve replacement (TAVR). The Edwards 16Fr eSheath+ Introducer Set may be used for the introduction and removal of the J-Valve TF System.

• Previous, or planned, other surgical or interventional procedures within 30 days before, during, or within 30 days after the index procedure
• Uncontrolled atrial fibrillation
• Severe right ventricular (RV) dysfunction or chronic inotrope support (>30 days)
• Severe pulmonary hypertension (systolic pulmonary artery pressure >80 mmHg measured by right heart catheterization)
• Severe chronic obstructive pulmonary disease (COPD) requiring chronic oral steroids or requiring continuous home oxygen
• Stroke (cerebrovascular accident, CVA), transient ischemic attack (TIA) or neurological signs and symptoms attributed to carotid or vertebrobasilar disease within 90 days prior to index procedure
• Estimated life expectancy of less than 12 months
• Pregnancy or intent to become pregnant prior to completion of all protocol follow-up requirements

Anatomic Exclusions:

• Ascending aortic diameter ≥5.5 cm as assessed by core lab
• Aortic annulus perimeter <57 mm or >104 mm as assessed by core lab
• Inappropriate anatomy for femoral introduction and delivery of the study system
• Congenital aortic valve disease including unicuspid, bicuspid, or quadricuspid aortic valve anatomy as assessed by core lab
• Congenital univentricle or other condition that, in the opinion of the investigator and/or consulting physician, may constitute an unwarranted surgical risk
• Excessive aortic valve prolapse or leaflet deterioration that would preclude proper seating of the implant in the aortic annulus
• Abdominal/thoracic aortic aneurysm ≥5.0 cm as assessed by core lab
• Aorto-iliac disease requiring intervention to facilitate delivery of access sheath
• Excessive tortuosity of delivery system pathway, defined as severe tortuosity of multiple vessels including iliofemoral, thoracoabdominal aorta, aortic arch, and/or LV-aortic root angle >80°
