Randomized Controlled TrialProphylactic tricuspid annuloplasty in patients with dilated tricuspid annulus undergoing mitral valve surgery.
Progression of functional tricuspid regurgitation is not uncommon after mitral valve surgery and is associated with poor outcomes. We tested the hypothesis that concomitant tricuspid valve annuloplasty in patients with tricuspid annulus dilatation (≥40 mm) prevents tricuspid regurgitation progression after mitral valve surgery. ⋯ Prophylactic tricuspid valve annuloplasty in patients with dilated tricuspid annulus undergoing mitral valve surgery was associated with a reduced rate of tricuspid regurgitation progression, improved right ventricular remodeling, and better functional outcomes.

Active ectopic thymus predicts poor outcome after thymectomy in class III myasthenia gravis.
The presence of ectopic thymic tissue has been considered one of the most significant predictors of poor outcome after thymectomy for myasthenia gravis, but the role of active ectopic tissue is unknown. The current study analyzed the importance of this factor on post-thymectomy outcome of patients with class III myasthenia gravis. ⋯ Extended thymectomy yields good outcome in patients with nonthymomatous class III myasthenia gravis. The presence of active ectopic thymus was the most significant predictor of poor outcome. These patients should be rigorously followed and undergo early aggressive therapy.
