Percutaneous Transluminal Caval-Flow Regulation PTCR®: A New Alternative Therapy to Reshape the Future Treatment of Heart Failure

Percutaneous Transluminal Caval-flow Regulation (PTCR) is an emerging alternative therapy to treat patients with acute heart failure (AHF). AHF represents the first cause of hospitalization in elderly persons and main determinant huge healthcare expenditure related (HF). Despite therapeutic advances, prognosis poor, in-hospital mortality ranging from 4% 7%, 60 90-day mortality. To reverse this situation, a balloon catheter medical device has been designed produce cyclic occlusions Inferior Vena Cava (IVC) supported by phases respiration, thus having subtotal occlusion during expiration total inspiration, producing intermittent regulation venous return or preload IVC right atrium. This PTCR procedure minimally invasive. It performed through insertion via femoral vein. advanced guided echocardiogram fluoroscopy be placed prior drainage hepatic At point, inflated up 70% 80% diameter expiration, which previously evaluated echocardiography. Then inspiratory collapse (20 30% average) produces inspiration partial thereby regulating caval flow manner. innovative aimed at hypervolemia present IVC, normalizing return, preload, intracardiac pressures, biventricular diastolic systolic diameters, volume, thus, obtaining reduction cardiac burden (TCB) reversal ventricular remodeling. In manner returns close its original design, improvement ejection fraction (EF) output.
