Abstract

We estimated the EHVAS in 4 goats and examined the effect of the automatic negative pressure control (ANPC) mechanism to prevent atrial wall sucking. ANPC regulates the filling power of the actuator automatically by monitoring sillicone oil pressure. Our EHVAS could be operated for 21-42 days. When ANPC was not used, instantaneous left atrial pressure during filling phase was-40mmHg, however, it was-10mmHg by using ANPC. ANPC could prevent atrial wall sucking. Our EHVAS could become a portable VAS.
