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 management,
follow-up,
and prognosis of various diseases including valvular heart disease.
Echocardiography had limitation for evaluation of RV function,
because of the complex shape of the RV,
and limitation of sonic window,
and the dependency of the operator.
Cardiac MRI (CMR) will make images of the whole heart in any plane with high accuracy and reproducibility,
so the CMR is gold standard for the assessment of RV morphology and function.
The purpose of this study is to investigate the association of the RV function measured by CMRI with clinical outcomes in patients who underwent tricuspid valvular surgery
