  De tidligste operationer af perikardiet (den sæk, der omgiver hjertet) fandt sted i det 19. århundrede og blev udført af Francisco Romero (1801), Dominique Jean Larrey (1810), Henry Dalton (1891) og Daniel Hale Williams (1893). Den første operation på selve hjertet blev foretaget af Axel Cappelen den 4. september 1895 på Rikshospitalet i Kristiania, nu Oslo, af Axel Cappelen. Cappelen bandt en blødende kranspulsåren hos en 24-årig mand, der var blevet stukket i venstre aksel og var i dybt chok ved ankomsten. Adgang var gennem en venstre thorakotomi. Patienten vågnede op og virkede fin i 24 timer, men blev syg med feber og døde tre dage efter operationen af mediastinitis.

  The earliest operations on the pericardium (the sac that surrounds the heart) took place in the 19th century and were performed by Francisco Romero (1801), Dominique Jean Larrey (1810), Henry Dalton (1891), and Daniel Hale Williams (1893). The first surgery on the heart itself was performed by Axel Cappelen on 4 September 1895 at Rikshospitalet in Kristiania, now Oslo. Cappelen ligated a bleeding coronary artery in a 24-year-old man who had been stabbed in the left axilla and was in deep shock upon arrival. Access was through a left thoracotomy. The patient awoke and seemed fine for 24 hours, but became ill with a fever and died three days after the surgery from mediastinitis.
