Nonregression or progression of tricuspid
regurgitation after MV surgery
Tricuspid regurgitation is frequently present months or years after
isolated mitral valve surgery.
Although repair of left-sided valve dysfunction may reduce the
severity of tricuspid regurgitation, a substantial proportion of patients
will go on to develop moderate or severe regurgitation.
In one series, 43% of patients had severe tricuspid regurgitation at a
mean follow-up of 11 years after isolated mitral valve replacement
Porter A, Shapira Y, Wurzel M, et al.: J Heart Valve Dis 1999, 8:57–62.
Although in some patients, significant tricuspid regurgitation will
resolve with correction of the left-sided lesion, there is no means of
accurately predicting this at the time of mitral surgery
