Viking Olov Björk (3 December 1918, Sunnansjö, Dalarna – 18 February 2009) was a Swedish cardiac surgeon.

In 1968, he collaborated with American engineer Donald Shiley to develop the first "monostrut tilting disc valve" used to replace the aortic or mitral valve.[1]

The Bjork–Shiley heart valve was manufactured by Pfizer after they bought the Shiley company in 1979. In 1980 Björk wrote to Pfizer threatening to publish cases of valve failures — often fatal to the patients — unless corrective action was taken. This eventually led to long lawsuit that involved the recall of all existing valves and Pfizer allocating up to US$20 million to pay compensation.[citation needed]

Björk died on 18 February 2009.[2][3]
