A Clinical Study to Evaluate Ambulatory Counterpulsation for the Treatment of Advance Heart Failure: A Feasibility Study
Are you eligible to participate in this study?
You may be eligible for this study if you meet the following criteria:
-
Conditions: Cardiogenic Shock
-
Age: Between 18 years - 120 years
-
Gender: Male or Female
-
Other Inclusion Criteria:
- Subjects who are at least 18 years old
- Female subjects who are postmenopausal or surgically sterilized, or have a negative pregnancy test within seven (7) days of invasive testing and who are using at least two reliable methods of contraception.
- Subjects with advanced heart failure refractory to guideline directed medical therapy needing circulatory support
- Subjects with abdominal aortic diameter > 1.9 cm proximal to the renal arteries
- Subjects with subclavian (axillary) diameter = 6.5 mm at site of planned iVAS implantation
You may not be eligible for this study if the following are true:
-
- Subjects with hypotension requiring any one of the following drugs:epinephrine, norepinephrine, vasopressin, methylene blue, phenylephrine or angiotensin II
- Subjects with single inotrope therapy dosing greater than the following: milrinone > 0.5 mcg/kg/min, dobutamine > 7.5 mcg/kg/min, dopamine > 7.5 mcg/kg/min, or epinephrine > 0.02 mcg/kg/min
- Subjects with dual inotrope therapy where the dosing of any one inotrope is greater than the following: milrinone = 0.25 mcg/kg/min, dobutamine = 3 mcg/kg/min, dopamine = 3 mcg/kg/min, or epinephrine = 0.01 mcg/kg/min
- Subjects who are supported by more than two inotropes at any dose
- Subjects with low blood pressure
- Subjects currently receiving circulatory support
- Subjects with subclavian stenosis or stent on the side of implantation or has greater than 80% carotid stenosis on side of implantation
- Subjects with aortic valve disease or significant abnormalities of the aorta
- Subjects with severe end-organ dysfunction or failure
- Subjects with pneumonia or systemic infection with bacteremia despite treatment
- Subjects with concomitant, non-cardiac disease process with life expectancy < 1 year.
- Subjects with inability to give informed consent due to altered mental status or dementia
- Subjects with any other condition the heart team believes inappropriate for this study
- Subjects with any condition other than dyspnea or fatigue of heart failure that would severely limit ambulation
