Exercise Capacity in Patients With Fontan Procedure
Condition: Single-ventricle; Fontan Procedure
MeSH terms: Univentricular Heart
Study type: Observational

Summary: 
      In literature, it has been reported that exercise capacity decreases in single-ventricle
      patients undergoing Fontan Procedure due to various factors related to surgery and underlying
      cardiac anomaly. Cardiopulmonary exercise test (CPET) was generally used to evaluate exercise
      capacity in children and adults with fontan circulation. The fact that CPET requires a
      clinically expert team and equipment and is more expensive does not always make it possible
      to perform routine cardiopulmonary exercise testing. In some cases, field tests evaluating
      submaximal and maximal exercise capacity may be more practical than cardiopulmonary exercise
      testing. Therefore, in this study, it is aimed to evaluate the exercise capacity of Fontan
      patients with 6-minute walking test and incremental shuttle walk test and to compare vital
      signs during the tests.
    


Intervention name(s): Demographic and clinical characteristics, incremental shuttle walk test, six minute walk test, hand grip strength, M. Quadriceps isometric muscle strength, body composition
Intervention type(s): Other
Intervention description(s): Demographic and clinical characteristics Age and complaints, post-operative follow-up, other problems, medications, ECHO and ECG findings, laboratory tests (complete blood count, liver and kidney function tests, brain natriuretic peptide (BNP) level)
Hand grip strength Right and left hand grip strength the highest of the three measurements
Lower extremity muscle strength Maximum isometric muscle strength of the quadriceps femoris
Body composition Body fat ratio, lean body weight and fat weight by bioelectrical impedance analysis
6 minute walk test The six minute walk test distance recorded in meters
Incremental shuttle walk test The lap number, the number of laps of the last level they can reach, and the walking/running distances recorded in meters
Observational model: Case-Control
Time perspective: Prospective
Sampling method: Non-Probability Sample
Study population: 
        The number of individuals to be included in the study was determined as 27 According to the
        power analysis at α=0.05 and β=0.20 (for 80% power). In this study, the medical information
        and medical records of the patients (patient files, computer records, etc.) will be
        examined and recorded. Patients aged 8-50 years who underwent the fonton procedure and were
        followed by Hacettepe University, Department of Pediatric Cardiology will be included in
        the study. The eligible patients will be referred to Faculty of Physical Therapy and
        Rehabilitation after the routine evaluations are completed. Control cases planned to be
        included in the study to be compared with the results of Fontan patients will be created by
        inviting the healthy relatives of the patients who applied to our faculty to participate in
        the study. In addition, control cases will be invited to work through an online
        advertisement.
