SCCT and six societies jointly created an expert consensus document on Cardiac CT for Prosthetic Heart Valve (PHV) Assessment, addressing the correct indications and patient selection for CT assessment of PHVs, image acquisition, reconstruction and measurement protocols, and interpreting and reporting the CT findings.

Cardiac CT in PHV assessment
Cardiac CT in PHV assessment
2025 expert consensus document

Cardiac Computed Tomography for Prosthetic Heart Valve Assessment is an SCCT-led expert consensus document co-authored by SCCT, the American College of Cardiology (ACC), the European Society of Cardiovascular Radiology (ESCR), the North American Society for Cardiovascular Imaging (NASCI), the Radiological Society of North America (RSNA), the Society for Cardiovascular Angiography & Interventions (SCAI), and Society of Thoracic Surgeons (STS).

 

 

According to the writing group, cardiac CT is a valuable, non-invasive imaging tool that uncovers the cause of PHV dysfunction in a way that is complementary to echocardiography.

The authors – comprised of radiologists, cardiologists and cardiac surgeons – explained that determining the root cause of PHV dysfunction is vital to identify the correct treatment strategy, which differs for each case.

Additional topics covered within the document include heart valve replacement technique; transthoracic echocardiogram (TTE) and transesophageal echocardiography (TEE) for PHV assessment; x-ray fluoroscopy for leaflet motion assessment of mechanical valves; CT acquisition protocols for PHV imaging; CT findings in normal functioning PHV; types of PHV dysfunction; additional findings important in case of planned re-op; and reporting.

“The document provides consensus statements by a group of international experts on how to perform, interpret and report cardiac CT scans performed for PHV assessment, based on best practices from the available literature and the expert experience."

Sara Ersoezlue, MD and Marta Belmonte, MD chat with writing group lead Ricardo Budde, MD, PhD, FSCCT to discuss the latest scientific document.

Top takeaways and key points:

  • The CT acquisition protocol should be tailored to the individual patient taking into account the type and location of the PHV.
  • Almost all PHV types can be adequately assessed both dynamically and statically with CT using dedicated image reformations to optimize the viewing planes.
  • Cardiac CT provides important information on the cause of PHV dysfunction that is complementary to echocardiography.
