Heart Valve Registry

xrayThe Heart Valve Registry was developed to track patient outcomes and complications following heart valve surgical procedures, including mitral, aortic, pulmonic and tricuspid. This registry has great potential to enhance quality of care through:
  • Identification and monitoring of all patients receiving these implants
  • Assessment of clinical best practices
  • Assisting in product analysis by tracking long term health outcomes
Data Collection and Sources

Like many of our newer registries, the Heart Valve registry relies exclusively on electronic data extraction. Data for this registry is exported from the comprehensive Society for Thoracic Surgeons (STS) Apollo database, supplemented by data from Clarity (KP HealthConnect), Scripps Hospital (San Diego) and St. Bernadine’s Hospital (Fontana). Health Plan membership and mortality data are updated monthly through KP’s Management and Information Analysis (MIA) Mortality and Membership datasets. In addition to patient demographics, risk factors and post-operative complications, the registry records the specific type of implant used for valve repair/replacement.

Volume and Participating Regions

The Heart Valve registry contains data from 2000 to present from the regions of Northern California, Southern California and Hawaii. Data from the Northwest region was added beginning in 2009. By year end 2011, the registry volume was almost 18,000 heart valves. Distribution of type of valve is 64% aortic, 32% mitral, < 1% pulmonic and 3% tricuspid.

Quality Control

This registry considers patient characteristics and implant selection as essential criteria to determining the success and longevity of heart valve procedures. Examples of critical outcomes include: re-operation for any reason, infection, peri-operative medical complications and death. As an initial project, our cardiothoracic surgeons used registry data to investigate longitudinal patient survival following mitral valve repair/replacement for tissue and mechanical valves as well as annuloplasty procedures.
