Left Ventricular Posterior Wall Pseudoaneurysm: A Rare Sequela of Mitral Valve Infective Endocarditis in a Chronic Patient of HLA-B27 Positive Spondyloarthritis

Left ventricular posterior wall pseudoaneurysm after native mitral valve infective endocarditis is a very rare occurance. We report such a case in a patient with HLA-B27-associated spondyloarthritis and normal coronary arteries. Excision of the aneurysm with left ventricular reconstruction and mitral valve replacement resulted in an excellent outcome.
