A nationale programme for combatting cardiovascular diseases is being implemented in Letvia. A milestone was reached in 1993 with the establishment of a Letvian Centre for Cardiology. Within 10 years the only cardiac catheterization unit in the country has developed into a centre of excellence. But to meet the cardiological needs for all of Letvia requires at least three additional units for left heart catheterization and one for paediatric a cardiac catheterization.
