Endocarditis in the 21(st) Century.

Endocarditis still carries a poor prognosis despite improvement in preventive strategies and advances in diagnosis and also in treatment. Epidemiology of infective endocarditis (IE) has changed in late years. Contemporary antibiotic overuse determines antibiotic resistance against microorganisms involved in IE.

A case of 75-year-old survivor of unrepaired tetralogy of Fallot and quadricuspid aortic valve.

In tetralogy of Fallot (TOF), the most common form of cyanotic congenital heart disease, only a few patients reach adulthood without surgical correction. We present the case of a man with TOF who survived until the age of 75 years without surgical intervention and had a very unusual combination of TOF and quadricuspid aortic valve (QAV). QAV, complicated by aortic regurgitation, is an uncommon finding in TOF patients.
