Outcome Measures

Primary Outcomes (1)

  • Right ventricular myocardial velocity

    Right ventricular myocardial velocity during early diastole (cm/s) Right ventricular myocardial velocity during late diastole (cm/s) Right ventricular myocardial velocity during systole (cm/s) baseline (one time point, measurements are performed at rest and during exercise)

    Baseline

Secondary Outcomes (1)

  • Peak oxygen consumption (ml/min/kg) and Oxygen consumption at anaerobic threshold (ml/min/kg)

    Baseline

Study Arms (2)

Fallot patients

EXPERIMENTAL

Fallot patients

Other: Transthoracic echocardiography at rest, during PLR, HG and CPX (including blood gas analysis in both groups). Additionally Fallot patients will undergo routine blood testings.

healthy controls

EXPERIMENTAL

healthy volunteers

Other: Transthoracic echocardiography at rest, during PLR, HG and CPX (including blood gas analysis in both groups). Additionally Fallot patients will undergo routine blood testings.

Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with corrected tetralogy of Fallot
  • Adult healthy controls without cardiovascular disease or other relevant systemic diseases with written consent

You may not qualify if:

  • Inability to give written consent, incapable of cycling or handgrip exercise due to cognitive or orthopedic limitation, poor echocardiographic image quality

Model Details: Transthoracic echocardiography including TDI is performed at rest, during PLR, HG and CPX in Fallot patients and healthy controls. In Fallot patients, transthoracic ultrasound at rest and during CPX are part of the routinely follow-up. PLR and HG were performed additionally as part of the investigator's study to analyze TDI parameters during various endurance testings
