I only learned of Dr. Radovanovic last year, through a documentary segment on Balkan medicine that a colleague sent me. The figure that stayed with me was 1984, the year he began operating at Sremska Kamenica with techniques he had carried back from Geneva and Houston. A remarkable life's work for someone I only ever knew through a screen.

Ninoslav Radovanovic was a Serbian cardiac surgeon and academician who founded open heart surgery at the Institute for Cardiovascular Diseases in Sremska Kamenica, near Novi Sad, and became one of the best known heart surgeons in Serbia. A full member of the Serbian Academy of Sciences and Arts, he performed more than 13,000 complex operations over his career. He died in Novi Sad on 10 November 2026 at the age of 86.
He was born in Nis on 6 May 1940 and completed primary and secondary school there before studying at the University of Belgrade School of Medicine, where he graduated on schedule with an average mark of 9.26. In 1967 he moved to Switzerland, working first in general surgery, and from 1970 trained in cardiovascular surgery in Geneva under Professor Charles Hahn. After five years he qualified as an assistant surgeon and then as a cardiovascular surgeon and consultant surgeon. He continued postgraduate training in Geneva, Paris and Houston.
Returning to Serbia, he founded the cardiac surgery service at the Institute for Cardiovascular Diseases in Sremska Kamenica and became its first director. By his own account he began operating there in 1984, and by the time he retired in 2006 the institute had carried out 26,000 open heart operations. He was a professor at the Faculty of Medicine in Novi Sad, a full professor from 1979, and published or co-authored more than 1,200 scientific papers. His innovations included a reductive annuloplasty of the mitral and tricuspid valves for patients with dilated cardiomyopathy, published in The Annals of Thoracic Surgery in 2002.
His time as director was not without controversy. He was removed as head of the institute in 1999, reinstated in 2001 after the political changes of October 2000, and removed again in 2006. He then went to Slovenia, where he founded a centre for cardiovascular surgery in Izola.
He was elected a corresponding member of the Serbian Academy of Sciences and Arts in 2003 and a full member of its Department of Medical Sciences in 2009. His honours included the Order of the Yugoslav Flag with Gold Star, the Order of Saint Sava First Class, the Order of Njegos First Class of Republika Srpska, the October Award of the City of Novi Sad and, in 2024, the Order of Sretenje First Class.
News of his death was shared by his colleague Professor Ilija Srdanovic, and many people responded with accounts of how he had saved their lives or the lives of relatives. The cause of death was not made public.

In their own words
“As the founder of cardiac surgery at the Institute for Cardiovascular Diseases in Sremska Kamenica, I began operations in 1984. I was active until 2006 when I retired, and in that time 26,000 open heart operations were performed.”

That documentary is worth tracking down, it covers the whole institute.
