[Long term results of the use of Björk-Shiley convex-concave heart valves. Ullevol hospital 1978-83].
In recent years, Björk-Shiley CC-valves have become the object of suspicion after several reports of strut fracture with embolization of the tilting disk and acute heart failure. At Ullevål Hospital Björk-Shiley CC-valves were used in 341 patients during the period October 1978 to March 1983. Strut fracture occurred in four cases, three of the patients died and one survived an emergency heart operation with replacement of the valve. In four patients, prophylactic replacement of the valves was performed. During the observation period concluded in September 1995 a total of 187 patients died. These included 26 operative deaths (7.6%). Of the late deaths, 40% were due to heart failure and 21% were sudden deaths. Strut fracture was the cause of death in 2% of the late deaths.
