Was an aortic valve replacement with a mechanical valve the right option all along? Cogan's syndrome with recurrent aortic regurgitation: a case of evolving surgical decisions.

Cogan Syndrome (CS) is a rare autoimmune disease, complicated by a variety of cardiac manifestations. This case report represents the only documented case in the Republic of Cyprus. It describes the experience of a 23- year-old woman with CS who presented with newly diagnosed, severe aortic regurgitation (AR) and suspected endocarditis. The patient was initially treated successfully with a Ross procedure, but the recurrence of acute AR a few years later, led to the decision to treat her with a mechanical valve replacement, minimising complications and providing as permanent of a surgical solution as possible. This case demonstrates the importance of individualising treatment for such patients.
