Tricuspid Valve Chordal Tissue in Endomyocardial Biopsy Specimens of Patients With Significant Tricuspid Regurgitation

Histologic evidence of chordal tissue in endomyocardial biopsy specimens was present in 47% of patients with significant TVR and did not relate to the number of biopsy procedures performed or the frequency of rejection episodes. This study provides histologic evidence that chordal tissue damage can occur after cardiac biopsy, resulting in significant TVR; however, it is clinically well tolerated by affected patients.
