Straight back syndrome as a clue to diagnosing asymptomatic congenital valvular heart disease and limiting the risk of weightlifting

Abstract

Although both are initially asymptomatic, mitral valve prolapse/myxomatous mitral valve disease (MVP/MMVD)andbicuspidaorticvalve(BAV),withits associated aortic disease, are currently the two most common congenital valvular heart diseases. Severe mitral regurgitation due to rupture of chordae tendineae (CTR) prompts surgery for MVP/MMVD. Surgery for BAV is performed for severe aortic stenosis and/or regurgitation, often with management of root and/or ascending aortic enlargement. There may be an association between straight back syndrome (SBS) and MVP/MMVD, which may be a key to earlier diagnosis. Other associations link weightlifting with ascending aortic enlargement and with CTR, where the common theme is blood pressure eleva-tion. As the number of people with fitness center memberships continues to increase, this potentially exposes more undiagnosed individuals with MVP/MMVD or BAV to risk from weightlifting. Challenges include making the public aware of this risk and preparing the osteopathic physician to recognize patients at risk through a structured history-taking and targeted cardiovascular examination.
