120 Cardiopulmonary exercise testing echocardiography features predicting the safety and efficacy of a central arterio-venous fistula with subgroup analysis assessing the impact of the device on blood pressure control and AF burden

Introduction: A central stent derived arterio-venous iliac fistula using the ROX CouplerTM reduces blood pressure (BP) in patients (pts) with resistant and/or uncontrolled hypertension (HTN). We performed detailed stress echocardiograms (echos) during concurrent cardiopulmonary exercise testing (CPET) pre and post insertion of a ROXTMCoupler for HTN. We evaluated the pre and post ROX Coupler characteristics of pts who might progress to cardiac decompensation. We evaluated the impact of perfect blood pressure control in a sub-analysis of paroxysmal atrial fibrillation (PAF) pts. using continuous heart rhythm monitoring with implantable cardiac monitors (ICMs).
