Levansri Makalanda,
Clinical lead, The Royal London hospital Barts NHS Trust, London, Interventional Neuroradiology
Karthik was a great asset to our department. He took on all the complex cases with abandon, treating to a very high standard and with excellent results. He was the first UK user of the Walrus balloon guide catheter and actively recruited into trials and registry. He was loved by the angio staff and clinical staff in equal measure and has been a loss since he has left.
