Multivalvular destruction as the primary presentation of aggressive infective endocarditis with subaortic valve membrane

Abstract

Multivalvular destruction may be a clinical manifestation of infective endocarditis (IE), which is a devastating infection of the heart either alone or superimposed with congenital subaortic membrane as in this case report. Here, we report a case of multivavular destruction with severe vegetation presented as a manifestation of infective endocarditis (IE) in a neglected case of 18-year-old male with previous rheumatic heart disease. Transesophageal echocardiography is an important imaging modality for diagnosis of superimposed aortic and heart lesions. Early necessary investigation and correct diagnosis is mandatory to prevent bad complications.

“…1−3 It mostly consists of a thin, crescent‐shaped membrane just below the AoV, it is more prevalent in men, and it may be complicated by infective endocarditis 1,2,4 . Most patients are asymptomatic, but for those who are symptomatic, the usual manifestation is exertional dyspnoea due to progressive LVOT obstruction, left ventricular hypertrophy, and AR 2,4,5 . The recommended treatment is simple membrane surgical removal 3,6 .…”

“…1,2,4 Most patients are asymptomatic, but for those who are symptomatic, the usual manifestation is exertional dyspnoea due to progressive LVOT obstruction, left ventricular hypertrophy, and AR. 2,4,5 The recommended treatment is simple membrane surgical removal. The imaging and surgical findings of the unusual LVOT structure were inconclusive in distinguishing an endocarditis-related aneurysm of the left coronary cusp from a congenital subaortic membrane.…”
