IntraVascular UltraSound (IVUS)

Three dimensional IVUS image reconstruction contributes to an improved insight on the anatomy of coronary arteries. 

IVUS measurements provide the following quantitative and qualitative data on the composition of the arterial wall:

Vessel Volume (VV)
Stent Volume (SV)
Lumen Volume (LV)
Plaque Volume (PV)

In-Stent neointimal Volume (ISV) calculated as SV-LV
Plaque Volume (PV) calculated as VV-LV

Area - Lumen, Vessel, Stent, Plaque (vessel/stent)
Diameter - Lumen, Vessel, Stent, Plaque (vessel/stent)
Symmetry - Lumen, Vessel, Stent, Plaque (vessel/stent)
Stenosis - Area Obstruction (vessel/stent), Diameter Obstruction (vessel/stent)

Our qualitative assessment consists of data on e.g. calcification, thrombus, dissection, improper stent placement or incomplete stent expansion.

Contour detection of lumen vessel and stent is automatically generated by our QIVA-system in a cross sectional view and in two longitudinal views.

Optical Coherence Tomography (OCT)

OCT analyses provide accurate assessment of stent apposition and tissue coverage over individual stent struts. Detailed assessment of the vessel wall and changes over time together with the characterisation of plaque components.

OCT analyses provide the following data: 

Lumen detection 
Stent strut detection 
Stent detection 
Prolapsed and mal-apposed area detection
Strut angle information

Visual assessment:

Morphological classification of individual stent struts.

Electrocardiogram (ECG)

Cordinamo provides reliable qualitative analyses of 12-lead ECG’s.

These measurements consist of the following data on e.g.:

Pathological Q-waves
ST-elevation or ST-depression
T-wave abnormalities/changes
Location of infarction or ischemia
ST-segment elevation resolution
