Clinical Trial Summary

The purpose of this prospective, single-armed, multi-center clinical trial is to further establish the safety and feasibility of using the BioVentrix PliCath HF System for the treatment of left ventricular dysfunction in appropriate cohorts of humans suffering from heart failure.

Description:

Congestive heart failure is the "epidemic" of cardiovascular disease (Eugene Braunwald, NEJM 1997), yet there is no cure. The American Heart Association reports the nearly five million Americans are afflicted. Approximately 1.5 million admissions in the US are due to heart failure; it is the number one cost-item for Medicare, comprising 6% of its total expenditures. BioVentrix has developed the PliCath heart failure system, which is used to place permanent cardiac implants into the heart for the purpose of excluding scar, reconfiguring abnormal cardiac geometry that is causing dysfunction, by excluding an abnormal portion of the ventricular wall. Conceptually, the final configuration in SVR can be achieved by placing these implants. The procedure called PliCath Epicardial Catheter-based Ventricular Restoration System (ECVR) is designed for left ventricular volume reduction in patients with heart failure in a magnitude similar to that of the predicate surgical procedure, but much less invasively. The PliCath HF System utilizes anchors that are implanted into the scarred portion of the heart, which when deployed, exclude some of the scar similar to what is excluded by cinching the purse string suture with the patch, rendering the ventricle smaller, and is employed in a surgical setting, with and without the use of cardiopulmonary bypass. The PliCath HF System has anchors (implants) that are deployed using fluoroscopic imaging.

Recruitment information / eligibility

Eligibility

Inclusion Criteria

• Age 18 - 80;
• Left Ventricular Ejection Fraction (LVEF) >15% and = 45%;
• NYHA FC II-IV;
• Left Ventricular End Systolic Volume (LVESVI) =60 cc/m² but = 120 cc/ m²
• Contiguous acontractile (akinetic and/or dyskinetic) scar located in the antero-septal, apical (may extend laterally) regions of the left ventricle as evidenced by a CMR or CT;
• Maintained standard medical management for at least 90 days, and at stable target (or maximum tolerated) dosages;
• Willing and competent to complete informed consent;
• Viability of myocardium in regions remote from area of intended scar exclusion as evidenced by CMR or CT;
• Agree to required follow-up visits Exclusion Criteria
• Calcified ventricular wall in the area of intended scar exclusion as verified by echocardiography or equivalent;
• Thrombus or intra-ventricular mass in the left atrium or ventricle as verified by echocardiography or equivalent;
• Cardiac Resynchronization Therapy (CRT) device placement = 60 days prior to enrollment;
• Significant diastolic dysfunction, defined as a pseudo-normal Doppler filling pattern with E/A ratio > 2;
• Thin walled, paradoxically moving septal scar that would preclude successful support of the anchor pairs as evidenced by CMR;
• Cardiac valve disease which, in the opinion of the investigator, will require surgery;
• Intolerance or unwillingness to take anti-coagulation medication;
• Functioning pacemaker leads in antero-apical RV, which, in the opinion of the investigator, would interfere with anchor placement;
• Pulmonary Arterial Pressure > 60 mm Hg via echo;
• Myocardial Infarction within 90 days prior to enrollment;
• Previous CVA or TIA which resulted, in the opinion of the investigator, in a significant residual neurological deficit;
• Aorto iliac disease that would preclude fem-fem bypass.
• Previous right neck surgery, previous pericardiotomy, previous left chest surgery;
• Co-morbid disease process with life expectancy of less than one year;
• Patients with lung, kidney and/or liver transplant;
• Chronic renal failure with a serum creatinine >2 mg/dL;
• Pregnant or planning to become pregnant during the study;
• Enrolled in any concurrent study other than observational.
