Cath Lab Teaching Course

Live medical procedures transmitted directly into a lecture theatre.


Sheffield Teaching Hospitals (STH) run an annual ‘Cath Lab Course’ which allows medical professionals a unique learning experience by combining lectures from some of the world’s most respected cardiothoracic surgeons along with live surgery from the hospital’s Cath Lab.  

STH called on Stream7’s expertise to transmit a live video feed from the Catheterisation Laboratory located at the Northern General Hospital to a large 200 seater lecture theatre in the hospital’s Medical Education Centre.


A catheterization laboratory or Cath Lab is an examination room in a hospital or clinic with diagnostic imaging equipment used to visualize the arteries of the heart and treat any stenosis or abnormality found. This provided a unique set of challenges for Stream7.

Pre-event our crew worked alongside the Audio Visual team at STH to fully test the video and audio links from the lab to the lecture theatre. This was an essential service to fault find and resolve any issues.

The Cath Lab was rigged with two cameras and a video feed from the diagnostic equipment. Audio came from a wireless headset microphone - specified by Stream7, which was worn by the surgeon, allowing him to talk the viewers through the procedure. The audio and video was then fed to the lecture theatre.


The Stream7 team provided a valuable resource to the event with our Director able to mix together the cameras and imaging providing the audience a remarkable experience. The system also allowed for the audio from the lecture theatre to be fed back to the Cath Lab, allowing a live question and answer session to take place. 

Our crew also managed the Powerpoint and audio for the presentations hosted in the lecture theatre providing a comprehensive service.

The event was a huge success and the prospect of live webcasting or recording the event for On Demand viewing has been suggested for the next event.
