Cardiorespiratory Assessment and Quality of Life After Surgical Correction of Congenital Wall Malformations

Not Applicable

Recruiting

• Conditions: Funnel Chest
• Interventions: Procedure: Surgical correction of pectus excavatum

• Registration Number: NCT03770390
• Lead Sponsor: University Hospital, Montpellier

Brief Summary

The main objective of this study is to characterize the cardiorespiratory functional gain in patients with pectus excavatum following corrective surgery.

Detailed Description

The secondary objectives are:

* To measure the quality of life of patients operated on for pectus excavatum

* Identify and describe post-operative complications

* Follow-up on the body mass index changes post-surgery

* Evaluate intraoperative hemodynamic parameters before and after the retrosternal bar is placed non-invasively
