Time to CR - 10,6 ± 3.4 d. | CR inpatient;
Length 18.3 ± 5.6 days;
Intervention: 6d/w
(1) Intensity according to clinical condition, 6MWT, disability
(2) In pts with mild disability interval or steady-state aerobic training and callisthenics was used. | (1) to determine the in-hospital and mid-term outcomes of these patients. | AE: NA
6MWT at discharge was significantly higher and corresponded to the 64% ± 23% of the predicted vs. 49% ± 21% in the admission test. | Most patients showed significant improvement in functional status, QoL, and autonomy, which remained stable in the majority of subjects during mid-term follow-up. |

Time to CR - 13,7 ± 11.7 d | CR inpatient;
Length 2 w;
Intervention:
70% predicted max HR, RPE 3 sets of exercises, 6 d/w: 30 min of respiratory workout, aerobic session on a cycle and 30 min of callisthenic exercises.
Aerobic session 10 min⟶30min | (1) The safety and efficacy of a structured, exercise-based CR program | AE: none
All enhanced autonomy; 6MWT did not significantly differ (272.7±108 vs. 294.2±101 m, p. 0.42), neither peak-VO2 12.5±3.6 vs. 13.9± 2.7 ml/kg/min, p. 0.16. | CR is feasible, safe and effective in octogenarian patients after TAVI as well as after traditional surgery. CR rehabilitation programme enhances independence, mobility and functional capacity and should be highly encouraged |

Female 48,9%;
AVR, MVR;
CD - mentioned;
Time to CR - 43±22 d | CR outpatient;
Length 12-20 weeks;
Intervention: 2-3/w for 60 min. Aerobic training, an intensity of the HR at AT combined with RPE. Strengthening exercises (15 minutes) at 60% of 1-RM for 2 sets of 15 to 20 repetitions. | (1) difference in exercise capacity early after VHD surgery
(2) whether the functional improvement after training was affected by risk or type of surgery | AE: NA
(1) Higher risk had a worse postoperative exercise capacity, higher VE/VCO2
(2) Exercise training - significant improvement in WL, peak VO2, AT, and 6MWD in each risk group (p <0.01).
(3) Significant decrease in the VE/VCO2 in the medium- and high-risk patient groups (p <0.05). | (1) Exercise capacity after VHD surgery is related to the preoperative risk and to the type of surgery.
(2) Similar benefit from exercise training can be obtained, independent of the preoperative risk class or the type of surgery. (3) ET should be offered to all patients after valvular surgery, regardless of their EuroSCORE risk or type of surgery |
