Abstract
Pectus defects are a group of congenital conditions found in approximately 1 in 250 people, where the sternum is depressed back towards the spine (excavatum), protrudes forwards (carinatum) or more rarely is a mixture of both (arcuatum or mixed defects). For the majority of patients, it is well tolerated, but some patients are affected psychologically, physiologically or both. The deformity becomes apparent at a young age due to the growth of the ribs and the cartilage that links them to the sternum. The majority of defects are mild and are well tolerated, i.e. they do not affect activity and do not cause psychological harm. However, some young people develop lower self-esteem and depression, causing them to withdraw from activities (such as swimming, dancing) and from interactions that might 'expose' them (such as sleepovers, dating, going to the beach and wearing fashionable clothes). This psychological harm occurs at a crucial time during their physical and social development. A small number of patients have more extreme depression of their sternum that impedes their physiological reserve, which can occur when engaging in strenuous exercise (such as running) but can also limit moderate activity such as walking and climbing stairs. The effects can be so extreme that symptoms occur at rest or cause life-threatening compression of the major blood vessels and organs. The group of patients with physiological impairment usually also suffer from low self-esteem and depression. This paper summarizes the current evidence for the different treatment strategies for this condition, including supportive care, psychological support and non-surgical techniques including bracing and vacuum bell therapy. We also consider surgical techniques including the Ravitch procedure, the Nuss procedure (minimally invasive repair of pectus excavatum), pectus implants and other rare procedures such as Pectus Up. For the majority of patients, supportive care is sufficient, but for a minority, a combination of the other techniques may be considered. This paper also outlines best practice guidance for the delivery of such therapies, including standardized assessment, consent to treatment, audit, quality assurance and long-term support. All the interventions have risks and benefits that the patient, parents and clinicians need to carefully consider and discuss when deciding on the most appropriate course. We hope this evidence review of 'Best Practice for Pectus' will make a significant contribution to those considerations and help all involved, from patients to national policy makers, to deliver the best possible care.

Walsh J, Walsh R, Redmond K. Systematic review of physiological and psychological outcomes of surgery for pectus excavatum supporting commissioning of service in the UK. BMJ Open Respir Res 2023; 10:e001665. [PMID: 37827806 PMCID: PMC10582895 DOI: 10.1136/bmjresp-2023-001665] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Accepted: 07/28/2023] [Indexed: 10/14/2023] Open
Abstract
BACKGROUND Pectus excavatum (PEx) is the most common congenital chest wall abnormality affecting 1 in 400 births in the UK. PEx is associated with significant physiological and psychological impairment. While readily surgically correctable, the benefits that surgery can bring have been debated and proven difficult to objectively measure. In the UK, this has led to the decommissioning of PEx surgery. The aim of this review is to conduct a systematic search of the literature on PEx surgery to assess physiological and psychological outcomes. METHODS A systematic review of the MEDLINE (PubMed), Embase and Cochrane databases was performed. Articles were sought which included patients undergoing surgery for PEx and reported on changes in cardiopulmonary measures, symptoms, quality of life and psychological assessments before and after surgical repair. Last search was performed in July 2022 and relevant findings were synthesised by narrative review. RESULTS Fifty-one articles were included in qualitative synthesis, with 34 studies relating to physiological outcomes and 17 studies relating to psychological and quality of life measures. Twenty-one studies investigated pulmonary function at rest. There was no change in forced vital capacity or forced expiratory volume in 1 second following open repair and transient reductions followed closed repair. In the 11 studies investigating echocardiography, transthoracic rarely demonstrated cardiac compression; however, transoesophageal demonstrated intraoperative relief in cardiac compression in severe cases. Sixteen studies investigated exercise testing (cardiopulmonary exercise testing, CPET), 12 of which demonstrated significant improvement following surgery, both in maximal oxygen consumption and oxygen pulse. Seventeen studies investigated quality of life, all but one of which showed improvement following repair of PEx. All papers that reported on patient satisfaction following surgery found high rates, between 80% and 97%. DISCUSSION While the majority of studies to date have been small and data heterogeneous, the literature shows that for many patients with PEx, there exists a cardiopulmonary limitation that while difficult to objectify, is likely to improve with surgical repair. Resting parameters offer little yield in aiding this except in the most severe cases. CPET therefore offers a better option for dynamic assessment of this limitation and improvements following repair. Surgery significantly improves psychological well-being and quality of life for patients with PEx.

Abstract
BACKGROUND Pectus excavatum frequently accompanies congenital heart disease and connective tissue diseases requiring cardiac surgery. Sometimes the indication is cardiac repair, with the pectus being incidentally noticed; other times, the pectus subsequently develops or becomes more significant after cardiac surgery. This review arms cardiac and congenital surgeons with background about the physiologic impact of pectus, indications for repair and repair strategies, and outcomes for cardiac surgery patients requiring pectus repair. METHODS A comprehensive literature review was performed using keywords related to pectus excavatum, pectus repair, and cardiac/congenital heart surgery within the PubMed database. RESULTS The risks of complications related to pectus repair, including in the setting of cardiac surgery or after cardiac surgery, are low in experienced hands, and patients demonstrate cardiopulmonary benefits and symptom relief. Concomitant pectus and cardiac surgery should be considered if it is performed in conjunction with those experienced in pectus repair, particularly given the increased cardiopulmonary impact of pectus after bypass. In the setting of potential bleeding or hemodynamic instability, delayed sternal closure is recommended. For those with anticipated pectus repair after cardiac surgery, the pericardium should be reconstructed for cardiac protection. For those undergoing pectus repair after cardiac surgery without a membrane placed, a "hybrid" approach is safe and effective. CONCLUSIONS Patients undergoing cardiac surgery noted to have pectus should be considered for possible concomitant or staged pectus repair. For those who will undergo a staged procedure, a barrier membrane should be placed before chest closure.

Usefulness of strain cardiac magnetic resonance for the exposure of mild left ventricular systolic abnormalities in pectus excavatum. J Pediatr Surg 2022; 57:319-324.

Abstract
BACKGROUND Systolic dysfunction in pectus excavatum (PEX) is usually very subtle and mainly focused on the right ventricle (RV), leading to normal or unremarkable cardiac imaging findings unless involving exercise stress. OBJECTIVES We evaluated systolic function in PEX using longitudinal strain cardiac magnetic resonance (CMR), a validated parameter for the assessment of the systolic deformation of subendocardial fibers. METHODS This prospective registry comprised consecutive patients with PEX who were referred to CMR to define treatment strategies or to establish surgical candidacy. We also included a control group of 15 healthy volunteers without chest wall abnormalities. Using dedicated software, we evaluated the endocardial global longitudinal strain (GLS) of both ventricles and the endocardial global circumferential strain (GCS) of the left ventricle (LV). RESULTS A total of 50 patients with PEX comprised the study population, with a mean age of 19.9 ± 8.0 years. The right ventricular ejection fraction (RVEF) of patients with PEX was significantly lower compared to the control group both at end-expiration (59.5 ± 6.8 vs. 64.7 ± 4.7%, p = 0.008) and end-inspiration (56.7 ± 7.2%, vs. 62.7 ± 4.4, p = 0.004); as well as the pulmonary stroke distance (12.6 ± 2.5, vs. 15.0 ± 2.0 cm, p = 0.001). The LV volumetric analysis revealed no differences between PEX and the control group (p > 0.05 for all) regardless of the respiratory cycle, with a mean expiratory LV ejection fraction (LVEF) of 61.4 ± 6.0%. In contrast, the GLS of the LV was significantly lower in PEX compared to controls (-21.2 ± 3.2 vs. -23.7 ± 3.0%, p = 0.010), whereas GCS was similar either at expiration (-28.5 ± 4.0%, vs. -29.5 ± 2.8, p = 0.38) or inspiration (-29.3 ± 4.1%, vs.-28.9 ± 2.3, p = 0.73). CONCLUSIONS In this study, we demonstrated that longitudinal strain analysis might enable the detection of very subtle left ventricular systolic function abnormalities in patients with PEX, that are commonly overlooked using the conventional assessment.

Abstract
Background Exercise training increases muscle VO2 by increasing O2 transport and O2 uptake while cardiac output increase might be limited by the conformation of the chest in subjects with pectus excavatum (PE). Aims The aim of the present study was to investigate the influence of physical activity (PA) on functional parameters of cardiopulmonary performance and stroke volume obtained at Cardiopulmonary Exercise Test (CPET) in PE. Methods and Procedures A cohort of adolescents (15 with PE and 15 age- and sex-matched healthy controls, HC) underwent Cardiopulmonary Exercise Test (CPET) and administration of the International Physical Activity Questionnaire – Short Form (IPAQ-SF) with estimation of weekly PA (METs h–1⋅week–1). Determinants of CPET parameters were investigated with multivariable linear regression analysis. Results As expected, when compared to HC, PE had lower VO2 max (37.2 ± 6.6 vs. 45.4 ± 6.4 mL⋅kg–1⋅min–1, p < 0.05), and VO2/HR max (O2 pulse, 12.1 ± 2.4 vs. 16.2 ± 3.6 mL⋅min–1⋅bpm–1, p < 0.05). Importantly, physical activity level was a predictor of VO2 max (adjusted for sex, body mass index, FEV1%, and presence of PE, β = 0.085; 95% Cl 0.010 to 0.160, p = 0.029) whereas O2 pulse was independent from PA level (β = 0.035; 95% Cl −0.004 to 0.074). Conclusion Physical activity is a determinant of VO2 max (cardiopulmonary performance), whereas it appears not to affect O2 pulse (a measure of stroke volume at peak exercise) related to constrained diastolic filling in PE.

Abstract
BACKGROUND Repair of pectus excavatum has cosmetic benefits, but the physiologic impact remains controversial. The aim of this study was to characterize the relationship between the degree of pectus excavatum and cardiopulmonary dysfunction seen on cardiac magnetic resonance (CMR) imaging, cardiopulmonary exercise testing (CPET), and pulmonary function testing (PFT). METHODS A single-center analysis of CMR, CPET, and PFT was conducted. Regression models evaluated relationships between pectus indices and the clinical end points of cardiopulmonary function. RESULTS Data from 345 CMRs, 261 CPETs, and 281 PFTs were analyzed. Patients were a mean age of 15.2 ± 4 years, and 81% were aged <18 years. The right ventricular ejection fraction (RVEF) was <0.50 in 16% of patients, left ventricular ejection fraction (LVEF) was <0.55 in 22%, RVEF Z-score was < -2 in 32%, and the LVEF Z-score was < -2 in 18%. CPET revealed 33% of patients had reduced aerobic fitness. PFT results were abnormal in 23.1% of patients. Adjusted analyses revealed the Haller index had significant (P < .05) inverse associations with RVEF and LVEF. CONCLUSIONS The severity of pectus excavatum is associated with ventricular systolic dysfunction. Pectus excavatum impacts right and left ventricular systolic function and can also impact exercise tolerance. The Haller index and correction index may be the most useful predictors of impairment.

The Nuss procedure for pectus excavatum: An effective and safe approach using bilateral thoracoscopy and a selective approach to use multiple bars in 296 adolescent and adult patients. PLoS One 2020; 15:e0233547.

Abstract
The Nuss procedure is a minimally invasive repair used to treat pectus excavatum. A bilateral thoracoscopy-assisted approach has been reported as a safe method for Nuss repair. The aim of this observational cohort study is to evaluate the application of the bilateral thoracoscopy-inspection to assist in the selection of the number of bars for correction of the pectus deformity in adolescents and adults. A retrospective chart review was performed on all adolescent and adult patients (296 patients: 257 male, 39 female; aged of 23.9 ± 7.7 years) with pectus excavatum primarily corrected with the modified Nuss repair from August 2014 to January 2018. The patients were divided into three age groups (A: 12 years ≦ age < 19 years, n = 73; B: 19 years ≦ age < 30 years, n = 175; C: age ≧ 30 years, n = 48). Advanced repair of deformed chest walls using more than one bar depended on the change detected via gross and perioperative thoracoscopy-inspection. The results showed that two or three pectus bars were used in 268 patients (90.5%). The overall complication rate after a postoperative follow-up of 28.6 ± 11 months was 6.8% (20/296), without mortality, major bleeding, or serious infectious complications. A multivariate logistic regression analysis showed that the complications were only associated with Haller index (adjusted OR = 1.2935, p = 0.0317) under controlling confounding factors. The postoperative sternovertebral distance was significantly improved from 7.3±1.6 to 10.1± 2.8 cm (p<0.001). The thoracoscopy-assisted approach of Nuss repair for correction of pectus excavatum was safe and effective approach and could also be used as an alternative approach for the selection of placed bars in adolescent and adult patients. Further studies regarding long-term outcomes are required.

Abstract
Pectus excavatum (PE) may cause symptoms and alter cardiopulmonary function. Left ventricular (LV) and right ventricular (RV) function have been reported to be impaired in PE subjects. However, this issue has not been systematically investigated with respect to the degree of chest wall abnormality. We aimed to evaluate the influence of severity of chest shape abnormality on myocardial strain parameters in PE subjects. We studied 30 healthy subjects (55.8 ± 14.0 year/old, 18 males) with PE, assessed by the ratio of chest transverse diameter over the distance between sternum and spine (modified Haller index, MHI, >2.5), and 30 controls (MHI ≤2.5) matched by age, sex, and cardiovascular risk factors. Participants underwent 2-dimensional (2D) transthoracic echocardiography implemented with 2D-speckle tracking echocardiography. Right-heart and left-heart chamber dimensions, and stroke volume, were significantly reduced in PE subjects (all P< 0.0001). While LV ejection fraction, E/A, and E/e', did not significantly differ between the 2 groups, all LV and RV strain and strain rate parameters were severely reduced in subjects with PE (P < 0.0001). Importantly, in PE subjects, but not in controls, LV global longitudinal strain, LV global circumferential strain, LV global radial strain, and RV free wall systolic strain, were all linearly correlated to MHI (all P < 0.0001). In healthy subjects with PE, abnormal chest anatomy progressively impairs myocardial strain. However, this impairment is not due to subclinical myocardial dysfunction; it might reflect intraventricular dyssynchrony due to compressive phenomena, or technical limitations of strain methodology, due to chest wall abnormality.

Abstract
Background Evidence of cardiac dysfunction in patients with pectus excavatum (PE) remains controversial. A growing number of studies report increased exercise tolerance following surgery. Nevertheless, many consider the correction of PE a cosmetic intervention, with post-operative changes ascribed to the concurrent growth of the young patient population. No studies have investigated non-invasively the immediate cardiac changes following relief of the deformity. The aim of this study was to assess cardiac function before and during temporary sternal elevation using the non-invasive vacuum bell (VB) device on young adults with PE. Methods Adult patients scheduled for surgical correction of PE underwent cardiac magnetic resonance imaging (CMRI) before and during the application of the VB. Steady-state free precession sequences were used for the evaluation of biventricular volume and function. Phase contrast sequences measured the aortic and pulmonary flow to calculate stroke index (SI). Scans were analyzed post hoc by the same investigator. A control group of healthy individuals was assessed in the same way. Results In total, 20 patients with PE (mean age 23±10 years) and 10 healthy individuals (mean age 25±6 years) underwent CMR before and during VB application. Before intervention, baseline cardiac volumes and function were similar between the groups, with patient-values in the low-to-normal range. Following VB application, PE patients revealed a 10% increase in biventricular SI. Furthermore, left ventricular end-diastolic volume index (LV EDVI) improved by 8% and right ventricular ejection fraction (RV EF) increased by 7%. These findings were not mirrored in the healthy individuals. No correlations were found between improved cardiac parameters and the baseline Haller index (HI) of PE patients. Conclusions Non-invasive, momentary correction of PE is associated with an immediate improvement in SI, RV EF and LV EDVI, not observed in controls. The findings suggest that sternal depression in PE patients affects cardiac function.

Abstract
STUDY DESIGN A prospective study of cardiopulmonary function in patients with congenital scoliosis (CS). OBJECTIVE To investigate the relationship of thoracic cage deformity and exercise tolerance in CS patients. SUMMARY OF BACKGROUND DATA Congenital thoracic scoliosis and chest deformity lead to restrictive pulmonary dysfunction and in some severe cases cause cardiopulmonary failure. However, it is still unknown the relationship between thoracic deformity and exercise performance. METHODS Patients with congenital thoracic spinal deformity were included and had radiological assessment of thoracic cage, pulmonary function testing, and cardiopulmonary exercise testing. Thoracic dimension including height, width, and depth were measured and geometry parameters were calculated. Two-tailed Pearson and Spearman correlation test and linear regression analysis were performed to investigate correlation of radiographic parameters, pulmonary function, and physical capacity. RESULTS Sixty patients (41 females and 19 males) were included, with an average age of 18.9 years. Patients with smaller thoracic height (P < 0.001) and width (P < 0.01) and larger depth (P < 0.05) had significantly worse static pulmonary function. In exercise testing, these patients showed significant tendency of ventilation insufficiency, including lower minute ventilation (P < 0.05), faster breathing frequency (P < 0.05), and smaller tidal volume (P < 0.01). Thoracic depth was negatively correlated to exercise capacity, reflected by work rate (P < 0.001), peak oxygen intake (P < 0.001), and heart rate (P = 0.043). Patients with abnormal thoracic geometry, especially a lower ratio of height to depth and a lower ratio of width to depth, have significantly worse static pulmonary function and exercise capacity (all P < 0.05). CONCLUSION Decreasing thoracic height and width results in restrictive pulmonary dysfunction. Distortion and asymmetry of the thoracic cage are associated with abnormal breathing pattern and reduction of exercise capacity. LEVEL OF EVIDENCE 3.

Abstract
Background The stability of the pectus bar is an important determinant of the success of pectus excavatum repair surgery. In practice, several different types of fixation method are in use for stabilizing pectus bars. The aim of this study was to compare the performance of the bridge fixation system with previous fixation systems for stabilizing pectus bars. Methods We performed a retrospective review of 1760 pectus excavatum repair cases conducted in the Thoracic Department of Choray Hospital and its satellite hospitals, between 2007 and 2017. We compared the results of 560 patients who had the bridge fixation system with the previous 1200 patients who had other fixation techniques. Results The bridge fixation system with 2 bars in 560 patients gave better results in terms of bar stabilization, operative time, and postoperative complications, compared to the previous 1200 patients who had other stabilization techniques. The average skin-to-skin surgery time using the bridge fixation system was 55 min. Of the 560 cases, only one patient showed trivial one bar dislocation, and one had a postoperative complication (pneumothorax). Conclusions We found the bridge fixation system to be superior not only in terms of stabilizing the bars but also for minimizing the time of surgery and postoperative complications, compared to other fixation systems. The bridge fixation system with 2 bars showed excellent results. Use of 3 bars is not necessary. One bar was used in the other fixation techniques and the results were found to be inferior compared to those using 2 bars.

Abstract
Exercise-induced dyspnea in children and adolescents can occur for many reasons. Although asthma is the common cause, failure to prevent exercise-induced asthma by pretreatment with a bronchodilator, such as albuterol, indicates that other etiologies should be considered. Other causes of exercise-induced dyspnea include exercise-induced vocal cord dysfunction, exercise-induced laryngomalacia, exercise-induced hyperventilation, chest wall restrictive abnormalities, cardiac causes, and normal physiologic limitation. When exercise-induced dyspnea is not from asthma, cardiopulmonary exercise testing with reproduction of the patient's dyspnea is the means to identify the other causes. Cardiopulmonary exercise testing monitors oxygen use, carbon-dioxide production, end-tidal pCO2 (partial pressure of carbon dioxide), and electrocardiogram. Additional components to testing are measurement of blood pH and pCO2 when symptoms are reproduced, and selective flexible laryngoscopy when upper airway obstruction is observed to specifically identify vocal cord dysfunction or laryngomalacia. This approach is a highly effective means to identify exercise-induced dyspnea that is not caused by asthma. [Pediatr Ann. 2019;48(3):e121-e127.].

Abstract
BACKGROUND Pectus excavatum, the most common congenital chest wall deformity in pediatric patients, leads to pulmonary dysfunction. There is no consensus regarding the effectiveness of the Nuss procedure for recovering pulmonary function. In this meta- analysis, we focused on the changes that occur in pulmonary function after the Nuss procedure. METHODS We performed a literature search in the MEDLINE, Embase, Cochrane library and PubMed databases. The included studies were required to contain pulmonary function tests with results adjusted to predicted values both before and after the Nuss procedure. The key outcomes of interest in this analysis were pulmonary function measured as forced expiratory volume in 1s (FEV1) and forced vital capacity (FVC). Subgroup analyses were performed based on time since surgery and the mean ages of the patients when they underwent surgery by forest plots and meta-regressions. RESULTS Thirteen studies involving 465 participants were included in this review. The standard mean difference (SMD) observed in FEV1 and FVC after surgery were 0.17 (95% CI, 0.01-0.33, p=0.04) and -0.18 (95% CI, -0.41-0.06, p=0.14), respectively. The overall meta-regression SMD of FEV1 and FVC by time since surgery were 1.21 (95% CI, 1.04-1.41, p=0.020) and 1.38 (95% CI, 1.05-1.83, p=0.027), respectively. We found evidence of a temporal relationship between time at which pulmonary function tests were performed after surgery and predicted FEV1 and FVC values. The SMD of FEV1 (0.26, p=0.012) was slightly higher in group evaluated more than 2year after initial surgery. CONCLUSIONS Abnormal resting pulmonary functions tests performed prior to surgery showed an initial depression after surgery. The FEV1 of patients slightly increased at 2year post surgery compared with the baseline. Further studies with longer term follow-up are still needed to determine if pulmonary function could improve to normal after surgery. LEVELS OF EVIDENCE Level of evidence: 4 (based on lowest level of article analyzed in meta-analysis/systematic review).

Abstract
Background An early observation after chest wall correction is direct inspection from the PE patient of their “new” thorax. Changes in self-perception may give raise to other psychological adaptations. The aim of this study was to evaluate the early changes in the fields of self-esteem, body image and QoL. Methods Prospective observational longitudinal multicenter cohort study. Self-esteem, emotional limitations and general health were assessed using the Child Health Questionnaire (CHQ) in patients under 18 and the World Health Organization Quality of Life Questionnaire-bref (WHOQOL-bref) was used for body image, psychological domain and overall QoL in patients over 16 years of age. Measurements were taken before surgery (T1) and 6 weeks (T2), and 6 months thereafter (T3). Results Scores on post-operative self-esteem were significantly higher compared with scores pre-operatively (p < 0.007). Also body image, psychological domain and emotional limitations showed significant improvement, respectively p < 0.001, p < 0.001, and p < 0.016. Significant improvement in the first three components was mainly achieved in the first 6 weeks post-operative. In emotional limitation, however, the largest change was between 6 weeks and 6 months. Overall quality of life in the WHOQOL-bref and general health domain in the CHQ showed no significant improvement in relation to the pre-operative scores. Conclusion Post-operative PE patients after Nuss procedure showed an improved body image, increased self-esteem and increased psychological resilience in the first 6 months, with the most marked change in the first 6 weeks. Also emotional limitations changed significantly over time. The changes were not large enough to influence general QoL or general health significantly.

Abstract
Minimally invasive repair of pectus excavatum has been successfully modified for use in adult patients. Many patients present in adulthood with progression of symptoms as the chest wall becomes less compliant with age. A thorough workup is completed including echocardiogram and chest CT to evaluate for anatomic abnormalities. Cardiopulmonary exercise testing is done to quantify the physiologic impact. Modifications of the original Nuss procedure required to allow for successful adult repair include the use of forced sternal elevation, the use of multiple bars, medial bar fixation, and interspace support to prevent bar rotation and migration. Occasionally, fractures may occur that require an open procedure and osteotomy or cartilage resection and hybrid approach incorporating the principals of intrathoracic support and osteotomy with bar stabilization.

Abstract
Pectus excavatum (PEx) is one of the most common congenital chest wall deformities. Depending on the severity, presentation of PEx may range from minor cosmetic issues to disabling cardiopulmonary symptoms. The effect of PEx on adult patients has not been extensively studied. Symptoms may not occur until the patient ages, and they may worsen over the years. More recent publications have implied that PEx may have significant cardiopulmonary implications and repair is of medical benefit. Adults presenting for PEx repair can undergo a successful repair with a minimally invasive "Nuss" approach. Resolution of symptoms, improved quality of life, and satisfying results are reported.

Abstract
Patients with pectus excavatum (PE) often describe improvements in exercise stamina following corrective surgery. Studies have investigated the surgical effect on physiological parameters; still, no consensus has yet been reached. Therefore, the aim of this literature review was to describe the cardiac outcome after surgical correction, both at rest and during exercise. In February 2016, a detailed search of the databases PubMed, Medline, and EMBASE was performed. We assessed clinical studies that described cardiac outcomes both before and after surgical correction of PE. We only included studies reporting either pre-defined echocardiographic or exercise test parameters. No exclusion criteria or statistical analyses were applied. Twenty-one full-text articles, published between 1972 and 2016, were selected, with cohort-ranges of 3-168 patients, mean age-ranges of 5-33 years, and mean follow-up-ranges from immediately to 4 years after surgery. Twelve studies described resting cardiac parameters. Four studies measured cardiac output, where one described 36% immediate increase after surgery, one reported 15% increase after Nuss-bar removal and two found no difference. Three studies demonstrated improvement in mean stroke volume ranges of 22-34% and two studies found no difference. Fifteen studies investigated exercise capacity, with 11 considering peak O2 pr. kg, where five studies demonstrated improvements with the mean ranging from 8% to 15% after surgery, five studies demonstrated no difference, and one saw a decrease of 19% 3 months after Nuss-bar implantation. A measurable increase in exercise capacity exists following surgery, which may be caused by multiple factors. This may be owed to the relief of compressed cardiac chambers with the increased anterior-posterior thoracic dimensions, which could facilitate an improved filling of the heart. With these results, the positive physiological impact of the surgery is emphasized and the potential gain in cardiac function should be integrated in the clinical assessment of patients with PE.

Abstract
BACKGROUND The impact of correction of pectus excavatum (PE) on adolescents' health-related quality of life (HRQL) has only been investigated in prospective designs using disease-specific measures and without controls. The aim of this prospective study was to evaluate the HRQL before and after surgical correction of PE using a generic HRQL measure, and to compare the reported level of HRQL before surgery with an age-comparable control group. METHODS Patients (n=107) and one of their parents (n=106) completed the generic HRQL measure: the Child Health Questionnaire before, 3 months, and 6 months after correction for PE. A control group (n=183) consisting of school children comparable in age completed the same measure on one occasion. RESULTS The patients' level of HRQL before surgery was comparable to the level of the controls except for physical functioning; here boys reported impaired function compared to controls (P<0.0001, d=0.72). Both patients and parents reported improved emotional wellbeing and self-esteem, as well as an increase in physical and social activities from pre- to post-surgery. These improvements were statistically significant (P≤0.001-0.03) and yielded moderate to high effect sizes (ƞ2=0.04-0.22). CONCLUSIONS The improvement of physical and psychosocial HRQL reported by both patients and their parents as proxy indicates the psychological implications of the deformity. Patients reported impaired physical function compared to controls. Further, pre-surgery differences in HRQL between the patients and the controls were lacking. However, the improvement in the patients' HRQL following surgery may justify the correction of pectus excavatum. The effect of the deformity on patients wellbeing compared with controls' needs to be addressed in further studies.

Abstract
OBJECTIVES To study if minimally invasive repair of pectus excavatum (PE) in adult patients would improve cardiopulmonary function at rest and during exercise as we have found previously in young and adolescent patients with PE. METHODS Nineteen adult patients (>21 year of age) were studied at rest and during bicycle exercise before surgery and 1 year postoperatively. Lung spirometry was performed at rest. Cardiac output, heart rate and aerobic exercise capacity were measured using a photo-acoustic gas-rebreathing technique during rest and exercise. Data are shown as mean ± standard deviation. RESULTS Fifteen patients completed the 1-year follow-up. No significant differences were found in neither cardiac output (14.0 ± 0.9 l min at baseline vs 14.8 ± 1.1 l min after surgery; P = 0.2029), nor maximum oxygen uptake (30.4 ± 1.9 and 33.3 ± 1.6 ml/kg/min; P = 0.0940 postoperatively). The lung spirometry was also unchanged, with no difference in forced expiratory capacity during the first second. CONCLUSIONS Correction of PE in adult patients does not improve the cardiopulmonary function 1 year after surgery as seen in children and adolescents.

Abstract
OBJECTIVE We aimed to assess the clinical outcomes of our surgical technique for repair of pectus excavatum using Prolene polypropylene mesh. METHODS Among 29 patients with pectus excavatum, the major complaint was cosmetic dissatisfaction, and the main symptom was exercise dyspnea in 15 patients. The Haller index used to assess pectus excavatum severity; it was significant in 22 patients. In all patients, a 2-layer sheet of Prolene polypropylene mesh was placed behind the sternum. RESULTS No serious complication was observed postoperatively, and all patients were satisfied with the cosmetic result. Mitral valve prolapse improved in all cases after 3 months. Spirometry revealed improved pulmonary function after surgery. CONCLUSION With due attention to the advantages of Prolene polypropylene mesh, such as remaining permanently in place, adapting to various stresses encountered in the body, resisting degradation by tissue enzymes, and trimming without unraveling, we concluded that this mesh is suitable for use as posterior sternal support in pectus excavatum patients.

Abstract
BACKGROUND To review the clinical experience and short- to middle-term effects of the Nuss procedure for correction of pectus excavatum (PE). METHODS From September 2006 to August 2014, 639 patients with PE were treated using the Nuss procedure. Of these, 546 were male and 93 were female. The mean age was 15.3±5.8 years (2.5-49 years). Preoperative chest CT scans Haller index (HI) was 4.3±1.7 (2.9-17.4), with 75 cases of mild PE (HI <3.2), 114 cases of moderate PE (HI 3.2-3.5), 393 cases of severe PE (HI 3.6-6.0), and 57 cases of extremely severe PE (HI >6.0). RESULTS A total of 638 patients successfully completed the surgery, an 11-year-old male patient who died after the surgery had undergone ventricular septal defect closure surgery through a sternal incision 7 years ago. The mean operative time was 64.3±41.7 min (40-310 min). Excluding the patient who died, the average blood loss was 24.5±17.8 mL (10-160 mL). The average length of postoperative hospital stay was 5.2±2.9 days (4-36 days). A total of 484 cases (75.7%) required 1 steel bar insertion, 153 cases (24.0%) required 2 steel bars, and 2 cases (0.3%) required 3 bars. Postoperative evaluation of the surgery outcomes revealed the following: excellent in 504 cases, good in 105, fair in 28 and poor in 2, good quality rate was 95.3%. CONCLUSIONS Correction of PE via the Nuss procedure is minimally invasive and simple to perform with good short and mid-term effects, while long-term efficacy remains to be determined.

Abstract
OBJECTIVES Pectus excavatum (PE) is often regarded as a cosmetic disease, while its effect on cardiac function is under debate. Data regarding cardiac function before and after surgical correction of PE are limited. We aimed to assess the impact of surgical correction of PE on cardiac function by cardiovascular magnetic resonance (CMR). METHODS CMR at 1.5 T was performed in 38 patients (mean age 21 ± 8.3; 31 men) before and after surgical correction to evaluate thoracic morphology, indices and its relation to three-dimensional left and right ventricular cardiac function. RESULTS Surgery was successful in all patients as shown by the Haller Index ratio of maximum transverse diameter of the chest wall and minimum sternovertebral distance [pre: 9.64 (95% CI 8.18-11.11) vs post: 3.0 (2.84-3.16), P < 0.0001]. Right ventricular ejection fraction (RVEF) was reduced before surgery and improved significantly at the 1-year follow-up [pre: 45.7% (43.9-47.4%) vs 48.3% (46.9-49.5%), P = 0.0004]. Left ventricular ejection fraction was normal before surgery, but showed a further improvement after 1 year [pre: 61.0% (59.3-62.7%) vs 62.7% (61.3-64.2%), P = 0.0165]. Cardiac compression and the asymmetry index changed directly after surgery and were stable at the 1-year follow-up [3.93 (3.53-4.33) vs 2.08 (1.98-2.19) and 2.36 (2.12-2.59) vs 1.38 (1.33-1.44), respectively; P < 0.0001 for both]. None of the obtained thoracic indices were predictors of the improvement of cardiac function. A reduced preoperative RVEF was predictive of RVEF improvement. CONCLUSIONS PE is associated with reduced RVEF, which improves after surgical correction. CMR has the capability of offering additional information prior to surgical correction.

Abstract
BACKGROUND Pectus excavatum (PE) is the most common anomaly of the anterior chest wall. Prior PE was corrected by a modified Ravitch operation, but since Nuss published his minimal technique in 1998, most surgeons have preferred this technique. METHODS Since 2001 the modified Nuss procedure has routinely been used for correction of more than 1,500 patients at Aarhus University Hospital. In the time period between January 1, 2011 and January 31, 2015, 675 patients have been corrected. The median age was 16 years (range, 11-58 years). All patients had preoperatively an epidural catheter and the operations were done in general anaesthesia. The postoperative pain treatment was planned for 4-5 weeks and the patients were routinely seen in the outpatient clinic 6 weeks after surgery and the bars removed after 3 years. RESULTS Four hundred-and-fifty patients had one bar, 216 patients with two bars and nine patients with three bars inserted. The median length of the bar was 10 inch. The median duration of the operation was 29 minutes. The median postoperative stay was 3 days. No death, cardiac perforation or deep infection occurred and only 5% of the patients experienced a complication. CONCLUSIONS The Nuss procedure should still be considered in the treatment of PE. To my opinion, it should be the choice for correction of PE. The short bar should be used to achieve the best stability of the system, to obtain a good cosmetic result, a reduced dysfunction motion of the chest wall and an increased cardiac performance.

Abstract
Background Differences in post-Nuss procedure pulmonary function based on the pectus excavatum subtype have not been investigated in adolescents. We evaluated differences in pulmonary function before and after the Nuss procedure according to preoperative morphology. Methods We performed a retrospective review of eighteen male patients who had undergone the Nuss procedures. There were nine patients each with symmetric and asymmetric morphology. Patients were younger than 18 years and had no history of respiratory diseases. Pulmonary function was assessed 2 weeks before and 4–6 months after the surgery. Preoperative and postoperative pulmonary function data were compared between the symmetric and asymmetric types. The paired t-test was used to compare the differences within each group and an analysis of covariance (ANCOVA) was used to access intergroup differences. Results There were no significant demographic differences between patients with symmetric and asymmetric subtypes. Patients with the asymmetric type had a lower preoperative total lung capacity (TLC) (p = 0.018), vital capacity (VC) (p = 0.0308), and inspiratory capacity (IC) (p = 0.0373). In both types, the forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and VC were all significantly decreased postoperatively compared to baseline (all, p < 0.01). The asymmetric type showed further reductions in peak expiratory flow (PEF) (p = 0.0391) and IC (p = 0.0084) postoperatively. The residual volume (RV) (p = 0.0092) and RV/TLC ratio (p = 0.0025) increased significantly in the asymmetric type, but only the postoperative PEF values differed significantly between the two types (p = 0.0151). Conclusions The asymmetric type had poorer preoperative lung volumes and poorer postoperative pulmonary function, with significantly lower PEF compared to the symmetric type cases. Preoperative and postoperative lung function needs more careful evaluation until pectus bar removal in the asymmetric type of pectus excavatum.

Abstract
BACKGROUND During exercise cardiac function is often limited in patients with pectus excavatum. Therefore, we hypothesized that cardiopulmonary exercise function would improve after the Nuss procedure. METHODS Seventy-five teenagers (49 patients, 26 controls) were investigated at rest and during bicycle exercise before surgery, and 1 year and 3 years postoperatively (after pectus-bar removal). Echocardiography and lung spirometry were performed at rest. Cardiac output, heart rate, and aerobic exercise capacity were measured using a photoacoustic gas-rebreathing technique during rest and exercise. RESULTS Forty-four patients and 26 controls completed 3 years follow-up. Preoperatively, patients had lower maximum cardiac index, mean ± SD, 6.6 ± 1.2 l·min(-1)·m(-2) compared with controls 8.1 ± 1.0 l·min(-1)·m(-2) during exercise (p = 0.0001). One year and 3 years postoperatively, patients' maximum cardiac index had increased significantly and after 3 years there was no difference between patients and controls (8.1 ± 1.2 l·min(-1)·m(-2) and 8.3 ± 1.6 l·min(-1)·m(-2), respectively [p = 0.572]). The maximum oxygen consumption was unchanged. Left ventricular dimensions increased in patients over 3 years; however, no difference was seen between the 2 groups. Preoperatively, patients had lower forced expiratory volume in the first second of expiration (FEV1; 86% ± 13%) as compared with controls (94% ± 10%), p = 0.009. Postoperatively, no difference was found in FEV1 between the 2 groups. CONCLUSIONS Before operation, FEV1 and maximum cardiac index were lower in patients compared with healthy, age-matched controls. One year after, both parameters had increased, although only FEV1 had normalized. After 3 years and bar removal, cardiopulmonary function in patients during exercise had normalized.

Abstract
BACKGROUND The "Nuss" repair is done for correction of moderate to severe pectus excavatum (PE). The long term cardiopulmonary and psychosocial effects of repair are uncertain. The objective of this study was to compare cardiopulmonary function and subjective evaluation of appearance and exercise tolerance pre-bar insertion with post-bar removal. METHODS All patients underwent preoperative and post-bar (3 month) removal evaluation with complete pulmonary function tests, exercise stress testing, echocardiogram, and self-rated appearance and exercise tolerance scoring. The protocol was approved by the regional ethics board, and all families gave informed consent. RESULTS Sixty-seven patients underwent pre and post testing. Preoperative CT index was 4.4 ± 1.3. Cardiopulmonary outcomes, standardized for height and weight, showed significant improvements in FEV-1 as (pre) 81.1 ± 17.0 vs post 89.8 ± 20.5*, FVC: 91.2 ± 18.6 vs 98.9 ± 22.9*, O2 pulse: 75.8 ± 14.4 vs 80.5 ± 18.3* (each as % predicted). Both the self-ratings of appearance (2.5 ± 0.8 vs 4.4 ± 0.5) and ability to exercise (3.3 ± 0.7 vs 4.3 ± 0.6, scale 1-5) increased significantly. (All data: mean ± St Dev, *p<0.05) CONCLUSIONS: Closed repair of PE results in improvements in pulmonary and aerobic exercise function and perceived appearance and exercise tolerance. Our data suggest that the impact on appearance and self-perceived well being is greater than the physical effect.

Abstract
A best evidence topic was written according to a structured protocol. The question addressed was 'Does repair of pectus excavatum (PE) improve cardiopulmonary function?' One hundred and sixty-eight papers were found using the reported search, 19 level III evidence papers and three meta-analyses were relevant. Studies were divided into four groups based on the surgical technique applied and pulmonary and cardiac functions in these groups were analysed. The meta-analyses show conflicting results for improvements in pulmonary and cardiac functions when comparing surgical techniques, while four more recent studies show improved long-term results using the Nuss technique. The best evidence of papers studying the PE repair using the minimally invasive Nuss technique demonstrates a decrease in pulmonary function during the early postoperative period, however, there is a small but significant improvement during the late postoperative period and after bar removal. The best evidence for cardiac function in this group suggests an early improvement that is sustained during further follow-up. The best evidence of papers studying the PE repair using the Ravitch technique shows that pulmonary function decreased during the early postoperative period, however, there is a small but significant improvement during the late postoperative period. The best evidence for cardiac function in this group suggests an early improvement that is sustained during further follow-up. The best evidence of papers studying the PE repair using other techniques (modified Daniel's technique, modified Baronofsky's technique, sterno-costal turn-over technique and sterno-costal elevation technique) or where surgical techniques used were not described (preceding year 1985) suggests that there is no improvement in pulmonary function after surgery. There is some evidence that certain aspects of cardiac function improved after surgery in this group.

Abstract
OBJECTIVES Pneumothorax is the most common complication after the Nuss procedure for pectus excavatum. The majority of pneumothoraces are small, and the patients have no symptoms. The aim of this study was to evaluate the necessity for routine chest X-ray immediately after surgery. METHODS Group I consists of 644 patients who were operated on with a Nuss procedure for pectus excavatum between 2001 and 2009 (85% male, median age 16 [range 7-48 years]) at Aarhus University Hospital. The standard procedure included chest X-ray immediately after surgery and before discharge. Group II consists of 294 patients (88% male, median age 16 [range 11-54 years]) who had a Nuss procedure in the period January 2011 to October 2012, where the standard procedure only included chest X-ray before discharge. RESULTS In Group I, pneumothorax was found on the chest X-ray obtained immediately after surgery in 333 (52%) patients. Fifteen (4.5%) were treated with chest-tube drainage. Six of these patients had no symptoms, but a 2- to 3-cm pneumothorax, 2 had progression of the pneumothorax and 7 had respiratory symptoms. The median size of those drained was 3 (range 2-6 cm). At the normal 6-week control, no pneumothorax remained. Group II: Among the 294 patients, 1 (0.3%) had a chest tube. CONCLUSIONS Only patients with respiratory symptoms after the Nuss procedure need a chest X-ray. A routine chest X-ray can be limited to the time of discharge where the position of the bar(s) is also checked.
