Ballad Health Has Resumed Regular Cardiovascular Surgery At Holston Valley Medical Center In Kingsport. The Surgeries Were Voluntarily Suspended Last Week After A Cluster Of Cardiac Deaths Occurred. Ballad Says It Was Atypical To Experience The Cluster So Close Together. A Review Concluded The Casualties Were Not The Result Of An Infection Or System Failure And Nothing Was Wrong With Ballad’s Standard Or Care.
