Continuous Quality Improvement and National Registries

Memorial Hermann Heart & Vascular is committed to quality outcomes and patient safety. We have embedded continuous quality improvement into our work and participate in several national registries which support our efforts to:

  • Develop best practices through data analysis and conversation with other leading health care organizations
  • Identify meaningful benchmarks
  • Examine efficiency and opportunities for process and cost improvements
  • Improve care through quality performance initiatives.

Our Heart & Vascular Care Participates in the Following Registries

Society of Thoracic Surgeons (STS) Registry (Cardiac Surgery Outcomes)

Our Memorial Hermann Heart & Vascular Service Line Medical Director was recently elected to serve on the Board of Directors of the Society of Thoracic Surgeons (STS) for 2022-2025.

The STS is responsible for creating the STS National Database for cardiac surgery which is the largest and longest running cardiac surgery quality initiative. The STS National Database was established in 1989 as an initiative for quality improvement and patient safety among cardiothoracic surgeons. The Database has four components—Adult Cardiac, General Thoracic, Congenital Heart Surgery, and the Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) Database. 

Data is publicly reported. As of June 2023, all Memorial Hermann acute care sites scored 2 or 3 stars out of 3 stars in almost every category.

The STS/ACC TVT Registry, created through a collaboration between STS and the American College of Cardiology (ACC), monitors patient safety and real-world outcomes related to transcatheter valve replacement and repair procedures – emerging treatments for valve disease patients. Employing state-of-the-art heart valve technology, transcatheter heart valve procedures provide treatment options for heart valve replacement or repair surgery.

Memorial Hermann TMC achieved 3 Stars (the highest level) for TVT.

Left Atrial Appendage Occlusion (LAAO) Registry (Left Atrial Appendage Occlusion Procedure Outcomes)

Memorial Herman is a member of the American College of Cardiology (ACC) registry, which captures data on left atrial appendage occlusion procedures to assess real-world procedural outcomes, short and long-term safety, comparative effectiveness and cost effectiveness.

Society of Vascular Surgeons Vascular Quality Initiative (VQI) Registry (Vascular Surgery Outcomes)

Memorial Hermann hosted the Spring 2023 Regional VQI meeting April 21, 2023, where all southern region members are invited to participate and share their experience and ideas.

Two key members of our affiliated medical staff provide leadership in the Southern Vascular Outcomes Network (SoVONet) comprised of vascular specialists in Texas, Arkansas, Oklahoma and Louisiana.

American College of Cardiology Public Reporting Registries

Cath PCI Registry (Cardiac Disease Patients Who Receive Diagnostic Catheterization and/or Percutaneous Coronary Intervention (PCI) Procedures Outcomes)

American College of Cardiology’s (ACC's) Public Reporting efforts help institutions bridge gaps between science and practice to improve the quality of cardiovascular care delivery. Hospitals participating in ACC's National Cardiovascular Data Registry (NCDR) programs have a unique opportunity to showcase publicly their commitment to continuous quality improvement, leading the way toward a more transparent health care system.

The American College of Cardiology (ACC) registry is available for any facility that performs PCI, captures the data that measure adherence to ACC/AHA clinical practice guideline recommendations, procedure performance standards and appropriate use criteria (AUC) for coronary revascularization.

Our team of affiliated physicians is developing and perfecting innovative techniques that continue to put Memorial Hermann at the forefront of advancing heart health in Houston. In fact, Memorial Hermann earned the highest star rating (4 stars) in every Percutaneous Coronary Intervention (PCI) metric during the 2022 calendar year.

Chest Pain MI Registry (Acute Myocardial Infarction Care Outcomes)

Memorial Hermann participates in the American College of Cardiology (ACC) registry “for outcomes-based, continuous quality improvement and … the go-to registry for hospitals and health systems applying American College of Cardiology (ACC) and American Heart Association (AHA) clinical guideline recommendations.”

All of Memorial Hermann’s 11 acute care hospitals are certified Chest Pain Centers.

Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) (Mechanical Circulatory Support Outcomes)

The STS INTERMACS Database is a North American registry for the clinical outcomes of patients who receive an FDA-approved mechanical circulatory support (MCS) device to treat advanced heart failure. The INTERMACS Database includes longitudinal data for the life of a patient with an MCS device. Approximately 36,000 patients currently are enrolled at more than 200 sites.”

Scientific Registry of Transplant Recipients (SRTR) (Heart and Lung Transplant Outcomes)

“SRTR supports the transplant community with analyses, in an effort to better patient results and experience.”

Site specific reports are available publicly through SRTR at
