Determination of the need for tricuspid valve replacement: value of preoperative right ventricular angiocardiography.
Of 530 patients undergoing tricuspid valve surgery from January 1, 1961 through December 31, 1987, those 362 patients having had preoperative right ventricular angiocardiography were studied.  Mean age was 58.5 years.  There were 71 males and 291 females.  Tricuspid valve replacement (TVR) was performed in 126 (34.8%), and 236 underwent tricuspid valve repair (65.2%).  The predominant pathology was combined tricuspid insufficiency and stenosis in 18 patients (4.9%), and isolated tricuspid insufficiency in 344 (95.1%).  There were no complications related to the right ventriculogram.  Preoperative angiographic severity of tricuspid valve incompetence was grade 1 in 23 patients (6.4%), grade 2 in 65 (17.9%), grade 3 in 109 (30.1%), and grade 4 in 165 (45.6%).  Intraoperative assessment of the severity of tricuspid valve incompetence correlated 72% of the time with the preoperative angiographic assessment, in those patients with more severe degrees of incompetence (grade 3+ or 4+), p (X 2) less than 0.001.  Increasing severity of preoperative angiographic triscuspid valve incompetence was associated with the requirement for TVR (vs. repair), p (X 2) = 0.0002.  In conclusion, preoperative right ventricular angiography is a useful method for assessing tricuspid valve function and may predict the requirement for TVR in patients undergoing tricuspid valve surgery.
