First recommendations published on imaging assessment of prosthetic heart valves

May 03, 2016

Sophia Antipolis, May 4, 2016: The first recommendations on multimodality imaging assessment of prosthetic heart valves are published today in European Heart Journal - Cardiovascular Imaging.1

The novel document was produced by the European Association of Cardiovascular Imaging (EACVI), a registered branch of the European Society of Cardiology (ESC). They are endorsed by the Chinese Society of Echocardiography, the Inter-American Society of Echocardiography, and the Brazilian Department of Cardiovascular Imaging.

"Prosthetic heart valves are the best treatment for the majority of patients with severe symptomatic valvular heart disease," said first author Professor Patrizio Lancellotti. "Heart valve disease is one of the most common types of cardiovascular disease and affects around 3-6% of the population over 65 years."

Heart valve replacement is performed using mechanical or biological prostheses. It is estimated that by 2050, some 850 000 prosthetic heart valves will be implanted every year in western countries.

Dysfunction of prosthetic heart valves is rare but can be life threatening. When it does occur, it is crucial to determine the cause as this will define what treatment is needed. The paper published today provides the first recommendations on how to use multimodality imaging to detect and diagnose prosthetic heart valve complications.

When prosthetic heart valve complications are suspected, the authors recommend:
  • First-line imaging with 2D transthoracic echocardiography (TTE)
  • 2D and 3D TTE and transoesophageal echocardiography (TOE) for complete evaluation
  • Cinefluoroscopy to evaluate disc mobility and valve ring structure
  • Cardiac computed tomography (CT) to visualise calcification, degeneration, pannus, thrombus
  • Cardiac magnetic resonance imaging (CMR) to assess cardiac and valvular function
  • Nuclear imaging, especially when infective endocarditis is suspected.


"In this paper we have underlined the incremental value of all imaging modalities to evaluate prosthetic heart valves," said Professor Lancellotti. "Echocardiography should be used in the first instance to detect any dysfunction. Non-echo imaging modalities can be performed afterwards if more information is needed to establish the cause and extent of complications."

He concluded: "We have introduced new algorithms to help clinicians diagnose and quantify prosthetic heart valve dysfunction. They are easy to use and we hope will improve assessment and subsequent management of patients so that when complications do occur, better outcomes can be achieved."

#537 Science Journalism, Hold the Hype
Everyone's seen a piece of science getting over-exaggerated in the media. Most people would be quick to blame journalists and big media for getting in wrong. In many cases, you'd be right. But there's other sources of hype in science journalism. and one of them can be found in the humble, and little-known press release. We're talking with Chris Chambers about doing science about science journalism, and where the hype creeps in.
