Impact of surgical treatment of pectus carinatum on cardiopulmonary function: a prospective study.

ABSTRACT:

Objectives

The frequency of sternochondroplasty in cases of pectus carinatum (PC) has increased due to greater surgeon experience and modified surgical techniques. PC deformity does not usually cause cardiopulmonary malfunction or impairment. However, whether cardiopulmonary function changes after surgical repair remains a matter of controversy. The aim of our prospective study was to determine if surgery changes preoperative cardiopulmonary function.

Methods

Nineteen patients (16 males, 3 females) were enrolled in a prospective, open-label, single-arm, single-centre clinical trial (Impact of Surgical Treatments of Thoracic Deformation on Cardiopulmonary Function) (NCT02163265) between July 2013 and January 2017. All patients underwent PC repair via a modified Ravitch procedure and wore a lightweight, patient-controlled chest brace for 8?weeks postoperatively (the Innsbruck protocol). The average follow-up surgical examination was 8.3?months after surgery. In all enrolled patients, before surgery and not before 6 months postoperatively chest X-ray, 3-dimensional volume-rendered computed tomography thorax imaging, cardiopulmonary function tests with stepwise cycle spiroergometry (sitting and supine position) and Doppler echocardiography were performed; questionnaires about daily physical activity were also completed.

Results

Fourteen patients (aged 16.3?±?2.6?years at study entry) completed the study. Changes in submaximal and peak power output were not detected during sitting, or when in the supine position. Also, no clinically relevant postoperative changes in spirometry or echocardiography were noted.

Conclusions

Our findings confirm that surgical correction of PC does not impair cardiopulmonary function at rest or during physical exercise.

Project description:BACKGROUND/PURPOSE:To report telemedicine's feasibility and satisfaction rates for treating patients with pectus carinatum using a dynamic compressor system. We analyzed treatment adherence in comparison with the previous, non-pandemic year. MATERIALS AND METHODS:Retrospective analysis including patients with pectus carinatum under treatment with a dynamic compressor system using telemedicine at the chest wall centers from two hospitals, private and public, between April and July 2020. A free video conference platform for teleconsultations was employed. We evaluated the incidence of pectus cases with telemedicine, the number of dynamic compressor system prescriptions, the number of patients in the correction phase, and the number who ended treatment. To assess adherence, we compared our cohort with an in-person cohort during the same time frame of the previous, non-pandemic year. In addition, we performed a patient satisfaction survey comprising questions related to socioeconomic status, the likeability of telemedicine, simplicity of modification of the system, and desire to continue with telepectus after the pandemic. RESULTS:One hundred and thirty-six telepectus consultations were performed in 76 patients. During this time frame, 15 patients started using the dynamic compressor system. Compared to the previous, non-pandemic year, the number of consultations per patient was similar (2019: 1.92 ± 1 .0 vs. 2020: 1.79 ± 0.8, p = 0.32), and there was a significant reduction in the number of dropouts with the use of telemedicine (9% vs. 1%, p = 0.025). Fifty-nine patients answered the satisfaction survey. All of them solved their doubts through telemedicine. Overall, 95% found telemedicine comfortable. Of note, those with a lower income evidenced the highest intention in continuing with telemedicine. CONCLUSIONS:We demonstrated the feasibility of remote care of patients with pectus carinatum using a dynamic compressor system with a similar frequency of consultations compared to in-person medical care. Telepectus patients revealed a high rate of satisfaction irrespective of their socioeconomic status. LEVEL OF EVIDENCE:IV. TYPE OF STUDY:Retrospective study.
