Brief Summary:
The Aortix CRS Pilot Study: An Evaluation of the Safety and Performance of the Aortix System for Intra-Aortic Mechanical Circulatory Support in Patients with Cardiorenal Syndrome

Condition or disease Intervention/treatment Phase
Heart Failure; With Decompensation Cardiorenal Syndrome Cardio-Renal Syndrome Heart Failure Heart Failure,Congestive Heart Failure, Systolic Heart Failure, Diastolic Device: Aortix System Not Applicable

Detailed Description:
The study is a prospective, multi-center, non-randomized feasibility study to evaluate the safety and performance of the Aortix System in patients hospitalized with acute decompensated heart failure (ADHF) and worsening renal function refractory to medical management with persistent congestion. The Aortix system consists of the Aortix Delivery System, Introducer Set, the Aortix Pump, the Aortix Control System, and the Aortix Retrieval System.

Aortix is a circulatory support device for chronic heart failure patients on medical management who have been hospitalized for acute decompensated heart failure (ADHF) with worsening renal function.

Primary Outcome Measures :
  1. Serious Adverse Events [ Time Frame: 30 days ]
    Rate of Occurrence of Serious Adverse Events (rate will be calculated and reported)

  2. Serious Procedure Related Adverse Events [ Time Frame: 30 days ]
    Rate of Occurrence of Serious Procedure Related Adverse Events (rate will be calculated and reported)

  3. Device Performance [ Time Frame: 7 days ]
    Deployment and retrieval procedures success rates (rates will be calculated and reported)

  4. Device Performance [ Time Frame: 30 days ]
    Rate of occurrence of ADS, ARS and pump device-related adverse events (includes device malfunctions) (rate will be calculated and reported)

  5. Effectiveness [ Time Frame: 7 days ]
    Clinically significant decongestion as measured by the PA catheter. Decrease in CVP or PCWP of > 20%.

  6. Urine Output [ Time Frame: 7 days ]
    Change in Urine Output Assessed as the hourly rate of urine output before pump placed vs hourly rate of urine output over the Aortix therapy period (until congestion target met or therapy deemed ineffective)

  7. BNP (Brain natriuretic peptide) [ Time Frame: 7 days ]
    Decrease in BNP or NT-pro-BNP by 20% (pre-implant vs when congestion target is met or therapy deemed ineffective)

2) Worsening renal function (serum creatinine increase by ≥0.3 mg/dl [≥27 μmol/L]) despite 48 hours of intravenous diuretic therapy Increase can be compared to a baseline value taken within 90 days of hospitalization or during hospitalization;

3) Objective measure of congestion (Elevated PCWP [≥20 mmHg] OR Elevated CVP [≥12 mmHg]) obtained via catheter measurement;

4) Persistent clinical signs and/or symptoms of congestion despite diuretic therapy (one or more of the following):

  1. dyspnea at rest or with minimal exertion,
  2. paroxysmal nocturnal dyspnea,
  3. orthopnea,
  4. lower extremity edema (≥2+),

    Exclusion Criteria:

    1) Treatment with high dose IV inotropes within the last 48 hours. High dose is defined as > 1 unit of inotrope (excluding digoxin) as follows: 5 µg/kg/min dopamine = 1 unit, 5 µg/kg/min dobutamine= 1 unit, 0.375 µg/kg/min milrinone = 1 unit, (for example, dopamine 2.5 µg/kg/min + dobutamine 2.5 µg/kg/min = 1 unit; dobutamine 2.5 µg/kg/min + milrinone 0.1875 µg/kg/min = 1 unit);

    2) Treatment with vasopressors to maintain blood pressure as per exclusion number 3;

    3) Active and ongoing hypotension defined as a systolic blood pressure < 90 mmHg lasting more than 30 minutes or a mean arterial pressure (MAP) < 60 mmHg lasting more than 30 minutes;

    4) Acute Kidney Failure defined as increase in serum creatinine to ≥4.0 mg/dL (≥353.6 μmol/L) within the last 48 hours;

  2. Abnormalities of the aorta or iliac arteries that would prevent safe device placement, including aneurysms, significant tortuosity, or calcifications,
  3. Ilio-femoral diameter or peripheral vascular anatomy that would preclude safe placement of a 21F (outer diameter) introducer sheath including severe obstructive calcification or severe tortuosity,
