Eligibility Criteria
Inclusion Criteria:
- Patients after valve surgery and/or intervention
- Age 65 years and older
- Ability to start CR within 4 weeks after surgery,
- 6-minute walk distance (6-MWD) ≥100- ≤350 m (1)
- Patient's agreement to participate in the study.
Exclusion Criteria:
- Diseases in the musculoskeletal system or other organs complicating physical activity and exercise training;
- Exercise-limiting comorbidities (primarily orthopedic and neurological conditions that would exclude individuals from participating in CR according to study protocol), including chronic heart failure New York Heart Association Class IV, hemoglobin less than 9 g/dL, wound healing disturbance, cognitive or linguistic deficits.

Intervention group
The supervised exercise program included: continues endurance training on cycle ergometers (6 sessions a week). Every session included warm up (<50% target intensity 2 min, gradually increasing load 1-10 w/min up to target intensity within 5 - 10 min); exercise phase (100% of the target intensity (30-50% watts or 30-50% HRmax), starting with >5 minutes and gradually prolonged up to 30 min); cool down with gradual reduction of the load within 3 minutes); additional aerobic exercises performed sitting and/or standing (30 minutes, 5 days/week); respiratory muscle training (7 days/week, for 15 minutes) using ball trainer.
Exercise program as for a control group together with additional resistance and balance training 3 sessions/week. The resistance training was started with low intensity (<30% 1-RM, RPE ≤ 11, 5-10 repetitions), increased gradually to moderate intensity (30-50% and up to 60% 1-RM, RPE 12-13, after 8-15 repetitions) with 3 sets and 3 minute rest between sets, if tolerated. The balance training included exercises to improve static as well as dynamic balance ability. It was performed on 2-3 days/week for 10-15 minutes. The complexity of the balance exercises was selected and incremented individually by changing the stand-position, the base on which the stands were performed and/or using unstable surfaces. If tolerated, the visual information was varied and/or additional tasks performed while balancing. After completion participants were encouraged to continue exercise training at home according to recommendations.
