Right ventriculography with a preshaped catheter (J- or L-shaped) was evaluated in make the diagnosis of tricuspid regurgitation. Thirty normal subjects who did not have valvular disease showed no evidence of tricuspid regurgitation or premature ventricular contractions during injection except in one case. On the other hand, 24 patients with combined aortic and mitral valve disease showed mild to moderate tricuspid regurgitation in 11 patients and severe tricuspid regurgitation in eight patients. Only two patients developed frequent run of premature ventricular contraction during injection. Seven patients with severe tricuspid regurgitation were found to have severe tricuspid regurgitation during surgery. No evidence of tricuspid regurgitation was found in all six patients with isolated aortic valve disease. We can conclude that right ventriculography by the preshaped catheter improves the diagnostic accuracy of tricuspid regurgitation and a grading system of tricuspid regurgitation by angiography is proposed.
使用预塑形导管（J形或L形）进行右心室造影，以评估其在诊断三尖瓣反流中的作用。30名无瓣膜疾病的正常受试者在注射过程中除1例患者外，均未显示三尖瓣反流或室性早搏的证据。另一方面，24例合并主动脉瓣和二尖瓣疾病的患者中，11例显示轻度至中度三尖瓣反流，8例显示重度三尖瓣反流。仅2例患者在注射过程中出现频发室性早搏。7例重度三尖瓣反流患者在手术中被发现有重度三尖瓣反流。所有6例孤立性主动脉瓣疾病患者均未发现三尖瓣反流的证据。我们可以得出结论，预塑形导管右心室造影提高了三尖瓣反流的诊断准确性，并提出了一种通过血管造影对三尖瓣反流进行分级的系统。
