Multiple recommendations for imaging in patients with suspected mechanical prosthetic valve thrombosis were combined into a single recommendation. Multimodality imaging with transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), fluoroscopy, and/or computed tomography (CT) scanning may be more effective than one imaging modality alone in detecting and characterizing valve thrombosis. Different imaging modalities are necessary because valve function, leaflet motion, and extent of thrombus should all be evaluated.

Multiple recommendations based only on NYHA class symptoms were combined into 1 recommendation.

Definition of Multivessel Disease

For AEGIS-II inclusion criteria #5, multivessel disease criteria can be met by findings on the cardiac catheterization for the index MI, a prior cardiac catheterization, or both:

  • Index MI cardiac catheterization: 50% or greater stenosis of the left main or at least 2 coronary artery territories (LAD, LCX, RCA) (prior to any interventions performed)
  • Prior cardiac catheterization: 50% or greater stenosis of left main or at least 2 coronary artery territories (LAD, LCx, RCA) (prior to any interventions performed)
  • Both: Index MI cardiac catheterization with 1 vessel with 50% or greater stenosis (prior to any interventions performed) AND prior PCI of at least 1 vessel different from index MI vessel
  • Prior multivessel CABG

Multivessel disease requires a 50% or greater stenosis in at least 2 of the 3 major epicardial artery territories (LAD, LCx, RCA) or the left main vessel. Branch vessel disease may qualify as part of the territory of that branch vessel (for example, a diagonal vessel is considered part of the LAD territory). For the purpose of this study, the ramus is considered part of the Left Circumflex artery territory. If a branch vessel is used as a qualifying vessel, that branch should be of large enough size to potentially undergo revascularization if clinically indicated, e.g. >2mm vessel size.

To determine if your patient meets the eligibility criteria for multivessel disease, please check all arteries/segments with 50% or greater stenosis on the cardiac catheterization for index MI and/or vessels that have received prior PCI (stent or balloon angioplasty).
