Image Database

| Case Studies

This database of intra-operative angiography image sequences is provided to demonstrate various capabilities of the technology and offer insight into improved imaging techniques. This database will be updated periodically so check back often for new and interesting images.

In-Situ Grafts

LIMA to LAD

Excellent image demonstrating good flow through graft and native coronary. Skeletonized LIMA provides clear picture of flow through graft. Image acquired on an arrested heart.

LIMA to LAD

Skeletonized LIMA clearly displays excellent flow through graft. Good flow and distal run-off is also observed through native coronary. Image acquired on a beating heart with stabilizer still in place.

LIMA to LAD

Image sequence demonstrates excellent flow through LIMA and LAD. Skeletonized LIMA allows complete flow pattern to be seen. Image clearly displays flow through all coronaries in the heart.

LIMA to LAD

Excellent flow through RIMA and native coronary is displayed. Last 2 cm of RIMA is skeletonized for improved visualization. Dark area at anastomosis site is from tissue overlap.

RIMA to LAD

Image sequence demonstrates excellent flow through the RIMA and good distal run-off through the RCA. Staples are visible along the RIMA. Good flow is also seen through the SVG.

Note: IC-Green reaches SVG prior to RIMA

LIMA to LAD

Excellent flow is observed through LIMA and LAD. Image acquired on a beating heart with the stabilizer still in place.

Free Grafts

RA to RCA

Image sequence displays good flow through graft and native coronary demonstrating a good functioning graft. Stabilizer arm is in view.

Demonstrates ability to "see" through RA

SVG to OM

Excellent flow is observed through graft and native coronary. IC-Green is manually injected. Image sequence performed on an arrested heart

SVG to PIV

Image sequence displays excellent flow through graft and native coronary. Anastomosis site is clearly visible.

SVG to RCA

Good flow through graft and native coronary is observed. Image sequence demonstrates ability to achieve great views on the posterior side of the heart. Retrograde flow is observed in graft as heart is lowered. Image sequence of proximal anastomosis should be acquired to verify flow is not compromised in normal position.

Multiple Grafts

LIMA to LAD; SVG to Diagonal

Competitive flow is initial observed in LIMA, but flow through graft into native coronary is eventually displayed. Good flow through the SVG to diagonal is observed. Of note, native flow is not seen in diagonal, only flow from the SVG.

Also, demonstrates perfusion deficit in diagonal without flow thorugh graft.

LIMA to LAD; SVG to Diagonal

Excellent flow observed in both grafts and native coronaries. Dark areas at anastomosis site indicate extra tissue on the surface of the heart. Good distal run-off in native coronaries demonstrates patent grafts.

RIMA to LAD; LIMA to Diagonal

Image sequence demonstrates excellent flow and distal run-off through both grafts and native coronaries. RIMA and LIMA are skeletonized for approximately last 2 cm of graft for improved observation of flow.

A leak is observed at anastomosis site

On-Pump

SVG to PDA

Excellent flow through the SVG and native coronary is demonstrated by this image sequence. The sequence was acquired on an arrested heart. ‘White-out’ at end is caused by injection of too much imaging agent.

SVG to OM

Excellent flow through the SVG and native coronary is demonstrated by this image sequence. The sequence was acquired on an arrested heart.

SVG to PDA

Excellent flow through the SVG and native coronary is demonstrated by this image sequence. The sequence was acquired on an arrested heart.
