Lessons of the month 3: Gone but not forgotten – Osler – a reminder of the syndrome not bearing his name

Transoesophageal echocardiography demonstrating aortic valve endocarditis with perforation of the left coronary cusp. The other two cusps were seemingly unaffected. There was severe aortic regurgitation and the left ventricle was dilated with poor systolic function globally. LA = left atrium; LCC = left coronary cusp; LV = left ventricle; MV = mitral valve; NCC = non-coronary cusp; RCC = right coronary cusp; RV = right ventricle.
