Trial Outcomes & Findings for Safety and Early Feasibility Study of the Harpoon Medical Device (EFS) (NCT NCT02771275)

NCT ID: NCT02771275

Last Updated: 2024-01-22

Results Overview

Procedural success was defined as the patient leaving the operating room with a successful implant of one or more ePTFE cords on the mitral valve and reduced mitral regurgitation from severe to \</=moderate at the conclusion of the procedure and at 30 days post-procedure.

SECONDARY outcome

Timeframe: 6 months, 12 months, 18 months, 24 months, 30 months, and 36 months

Population: This outcome is reported for subjects who received the Harpoon Medical Device where data is available.

Valvular regurgitation occurs when the valve in the heart does not close tightly allowing some of the blood that was pumped out of the heart to leak back into it. Valvular regurgitation is evaluated by echocardiography over time. It is assessed on a scale from 0 to 4, where 0 represents no regurgitation and 4 represents severe regurgitation. The numbers on the scale are reflected as follows: 0 = no leak, 1 = a trace leak, 2 = a mild leak, 3 = a moderate leak, and 4 = a severe leak. Higher numbers on the scale show a worsening outcome.
