Coronary heart disease deaths in 25 years. The experience in the three Serbian cohorts of the Seven Countries Study.

Three cohorts of men aged 40-59 at entry examination were enrolled between 1962 and 1964 in the Serbian section of the Seven Countries Study of Cardiovascular Diseases. They were a sample in the rural village of Velika Krsna (n = 511), the workers in an agro-industrial cooperative in the city of Zrenjanin (n = 516), and the University professors of Belgrade (n = 536). At entry examination and then after 5 and 10 years, some cardiovascular risk factors were measured while the follow-up for mortality and causes of death was continued for 25 years.

Late thrombosis of the Björk-Shiley tilting disc valve in the tricuspid position. Thrombolytic treatment with streptokinase.

The main complication after implantation of a Björk-Shiley tilting disc valve in the tricuspid position is late thrombotic obstruction. Of 28 patients with tricuspid valve replacement (16 with mitral, aortic, and tricuspid valve replacement; 12 with mitral and tricuspid valve replacement), with a mean follow-up of 5.2 years, seven (25%) had thrombosis of the tricuspid prosthesis.
