Right ventricular remodeling stratified for left ventricular function:
RV dysfunction was prominent in the 18 patients with baseline LVEF <35%: RVFAC 25±9%; RVFWLS -13±5%; RVS’ 6.5±2.1cm/s; TAPSE 1.3±0.5cm; PASP 48±14mmHg) (Table 6). After TMVI, RV function improved at 3-months, with an increase in RVFAC (to 35±11%, p=0.03) and reduction in PASP (to 32±9mmHg, p=0.01, Table 6). There were non-significant increases in RVFWLS, RVS’ and TAPSE (Table 6).
Patients with a LVEF ≥35% had less severe RV dysfunction before TMVI compared to patients with a LVEF <35% (RVFAC 29±5%; RVFWLS -15±5%; RVS’ 7.9±2.8cm/s; TAPSE 1.4±0.4cm; PASP 47±17mmHg) (Table 6). In this group, RVFAC also increased to 35±8% (p=0.01) and PASP decreased to 34±12mmHg (p=0.01) 3-months after TMVI (Table 6). There were non-significant increases in RVFWLS and TAPSE (Table 6).
