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 30%,
and remaining 70% were performed valvuloplasty.
Most common combined operation was MV surgery,
accounting as 63%,
and followed Maze operation.
Preoperative echocardiography showed functional tricuspid regurgitation was 91%,
normal MV was 40%,
most of AV and PV showed normal valvular morphology.
Our outcome of all death was only 9 pts,
so we performed the analysis for these patients.
Univariate analysis result for all cause of death showed statistically significant different in LV and RV end diastolic and end systolic volume index,
LV and RV mass index,
echocardiographic LV EF.
Among them,
especially RV parameters showed more significant P-value difference (Table.1).
In multivariate analysis of all death,
c-index was calculated,
and showed additional value to predict survival in especially RV volume index and RV mass index (Table.2).
The survival curves according to median LV EDVI and ESVI by K-M method shows no significant different between two groups (Fig.1).
But,
the survival curves according to median RV EDVI and ESVI showed statistically significant difference (Fig.2).
