Aims and objectives

It is well known about poor prognosis of tricuspid valve (TV) surgery, according to the literatures, the hospital mortality of TV surgery was reported upto 25%. There were known prognostic factors of the TV surgery, as clinical parameters, coronary artery disease, increased NYHA functional class, prior cardiac surgery, advanced heart failure, significant primary pulmonary disease, male gender, and as echocardiographic parameters, right ventricle (RV) index of myocardial performance, RV mid-cavity diameter, TV tethering area, and so on. RV functional parameters would give important information for...

Methods and materials

In our institution, there were 841 patients who underwent TV surgery during about 7 years, and among them, 111 consecutive patients who had preoperative cardiac MRI were enrolled in this study. Mean age of the patient was 55.8 years old, mean MRI - Operation interval time was 22.7 days, and median F/U duration was 417 days. The cardiac MRI was achieved by 1.5-T machine. Using the commercially available software (CVI® Version 5.0, Circle Cardiovascular Imaging Inc., Canada), we measured the RV and left ventricle (LV)...

Results

Among 111 patients, all cause of death was 9, cardiac causes of death were 5 and composite outcome of all death plus re-hospitalization were 34. Men were about 33%, DM was 16%, HTN was 24%. More than a half of pts had atrial fibrillation. Thirty-two percent of patients had this TV surgery as redo or tri-do operation. As previous valvular surgery, mitral valve (MV) was most common site, and counting as 28%, followed by TV surgery. In this TV surgery, TV replacement was performed as...

Conclusion

In conclusion, RV measurement by CMRI may be used for prediction of poor prognosis in patients who underwent tricuspid valvular surgery.
