RESUMO
INTRODUCTION: Chest wall deformities often become apparent with growth spurts during adolescence. Alterations in the structure of the chest wall can result in the development of pulmonary bullae and blebs, which may lead to spontaneous pneumothorax. There are limited data on this subject in the literature. In this study, it is aimed to investigate the presence of bullae and bleb in patients with anterior and posterior chest wall deformities. METHODS: Computed tomography scans of adolescent idiopathic scoliosis, pectus carinatum, and pectus excavatum patients were analyzed. The presence of bullae and/or bleb (BB) was recorded as "present" or "absent." RESULTS: One hundred fifty patients with chest wall deformity have been included in the study. BB has been detected in 55 (36.7%) of the patients. Surgical procedures were performed in 45 (30%) of the patients due to chest wall deformity. BB was present in 12 (26.7%) of these patients. A statistically significant difference has been found between the presence of complications and the presence of BB in surgical patients (P < 0.001). In patients who developed complications, there was a statistically significant difference between the presence of BB and the duration of chest tube follow-up (P = 0.031), as well as between the presence of BB and the length of hospitalization (P = 0.006). CONCLUSIONS: A significant proportion (36.7%) of patients with chest wall deformity had BB. Chest wall deformities and primary spontaneous pneumothorax (PSP) may have common etiologic factors. It should be kept in mind that patients with chest wall deformities may be potential PSP patients. Medical counseling about PSP should be considered for these patients.
RESUMO
INTRODUCTION: Our study assesses the association between cryoablation, with and without nerve block supplementation, post-Nuss procedure pain, and opioid use in pectus excavatum (PE) patients. METHODS: We conducted a retrospective cohort study at a single center for PE patients who underwent the Nuss procedure from 2017 to 2022. Outcomes included postoperative opioid use (measured in oral morphine milligram equivalent per kilogram [OME/kg]), average pain score (scale 0-10), and length of stay (LOS). RESULTS: One hundred sixty-four patients (146 males and 18 females) were included, with 79 (48.2%) receiving neither cryoablation nor nerve block, 60 (36.6%) receiving intraoperative cryoablation alone, and 25 (15.2%) receiving both cryoablation and nerve block. The median age was 16 y. Nerve block recipients consumed fewer opioids during hospitalization than cryoablation alone and nonintervention groups (1.5 versus 2.3 versus 5.8 OME/kg, respectively, P < 0.0001). Average pain scores over the total LOS were lower in nerve block recipients (3.5 versus 3.8 versus 4.2, P = 0.03), particularly on postoperative day 0 (P = 0.002). Nerve block recipients had a shorter LOS than cryoablation alone and nonintervention groups (43.4 versus 54.7 versus 66.2 h, P < 0.0001). On multivariate analysis, cryoablation alone resulted in significantly less opioid use compared to no intervention (3.32 OME/kg reduction, 95% confidence interval -4.16 to -2.47, P < 0.0001). Addition of nerve block further reduced opioid use by 1.10 OME/kg (95% confidence interval -2.07 to -0.14, P = 0.04). CONCLUSIONS: Cryoablation with nerve block supplementation is associated with reduced pain, opioid use, and LOS post-Nuss for PE repair compared to cases without cryoablation or with cryoablation only. Cryoablation with regional nerve blocks should be considered for Nuss repair under the enhanced recovery after surgery pathway.

INTRODUCTION: Pectus excavatum is the most prevalent chest wall deformity. Repair may be offered via Nuss or Ravitch technique. This study aims to investigate the outcomes of these repairs using a national cohort. METHODS: The Nationwide Readmission Database was queried from 2016 to 2020 for patients aged 12-21 y old with pectus excavatum. Demographics, hospital characteristics, and outcomes were analyzed using standard statistical tests. The results were weighted for national estimates. RESULTS: A total of 10,053 patients with pectus excavatum underwent repair (86% Nuss, n = 8673 and 14% Ravitch, n = 1380). Baseline characteristics were similar between cohorts. Nuss repair patients traveled more frequently out of state for repair (10.5% versus 8.7%) and were in the highest income quartiles (61.1% versus 57.3%), both P < 0.05. Of reporting hospitals, 60% performed only the Nuss procedure. The Ravitch cohort experienced higher rates of complications during index admission, including chest tube placement (5.1% versus 2.2%), bleeding (2.4% versus 0.6%), air leak (0.9% versus 0.3%), and respiratory failure (1.0% versus 0.3%), as well as longer median length of stay (4 versus 3 d), all with a P value < 0.05. While both cohorts had similar overall readmission rates, Ravitch repairs had higher rates of readmissions for bleeding (18.3% versus 4.5%), pain (32.9% versus 13.5%), and psychiatric complications (31.7% versus 21.2%), all with a P value < 0.05. Ravitch repairs also incurred higher total hospital costs ($18,670 versus 17,462, P < 0.001). CONCLUSIONS: Nuss repairs were associated with fewer index complications with no increase in readmissions compared to Ravitch procedures. However, disparities may exist in access to Nuss repair.
RESUMO
INTRODUCTION: Patients with pectus excavatum (PE) often undergo cross-sectional imaging (CSI) to quantify severity for insurance authorization before surgical repair. The modified percent depth (MPD), an external caliper-based metric, was previously validated to be similar to the pectus index and correction index. This study explored family perceptions of CSI and MPD with respect to value and costs. METHODS: This is a cross-sectional survey study including families of patients enrolled in an ongoing prospective multicenter study evaluating the use of MPD as an alternative to CSI for quantifying PE severity. Families of PE patients who underwent both MPD and CSI completed a survey to determine their perceptions of MPD and costs of CSI. Responses were described and associations were evaluated using chi squared, Wilcoxon rank-sum test and logistic regression as appropriate. Statistical significance was set to 0.05. RESULTS: There were 136 surveys completed for a response rate of 88%. Respondents were confident in MPD (86%) and confident in its similarity to CSI (76%). Families of females were less confident in the measurements than males (55% versus 80%, P = 0.02; odds ratio 0.30 (0.11, 0.83). Obtaining CSI required time off work/school in 90% and a copay in 60%. Nearly half (49%) of respondents reported CSI was a time/financial hardship. Increasing copay led to decreased reassurance in CSI (55%: copay > $100 versus 77%: lower copay/75%: no copay; P = 0.04). CONCLUSIONS: From the family perspective, MPD is valuable in assessing the severity of PE. Obtaining CSI was financially burdensome, particularly for those with higher copays. MPD measurements provide high value at low cost in assessing the severity of PE.

BACKGROUND: Lung transplantation (LTx) is a crucial therapeutic strategy for patients suffering from end-stage respiratory diseases, necessitating precise donor-recipient size matching to ensure optimal graft function. While standard allocation protocols rely on predicted lung capacity based on factors such as sex, age, and height, a subset of patients with respiratory diseases presents an additional challenge - thoracic or vertebral deformities. These deformities can complicate accurate volume predictions and may impact the success of lung transplantation. METHODS: In this retrospective cohort study of patients who underwent LTx at Tohoku University Hospital between January 2007 and April 2022, with follow-up until October 2022, the primary objective was to assess the influence of thoracic and vertebral deformities on perioperative complications, emphasizing interventions, such as volume reduction surgery. The secondary objective aimed to identify any noticeable impact on long-term prognoses in recipients with these deformities. RESULTS: Of 129 LTx recipients analyzed, 17.8% exhibited thoracic deformities, characterized by pectus excavatum, while 16.3% had vertebral deformities. Perioperative complications, requiring delayed chest closure, tracheostomy, and volume reduction surgery, were more prevalent in the deformity group. Thoracic deformities were notably associated with the need for volume reduction surgery. However, long-term prognoses did not differ significantly between patients with deformities and those without. Vertebral deformities did not appear to significantly impact perioperative or long-term outcomes. CONCLUSIONS: This study highlights the prevalence of thoracic deformities in LTx recipients, correlating with increased perioperative complications, particularly the potential need for volume reduction surgery. Importantly, these deformities do not exert a significant impact on long-term prognoses. Additionally, patients with vertebral deformities, such as scoliosis and kyphosis, appear to be manageable in the context of LTx.

BACKGROUND: Stress cardiomyopathy (SCM) is an acute heart failure syndrome characterized by transient, usually reversible left ventricular systolic dysfunction with normal or enhanced basal compensatory wall motion abnormalities involving the left ventricular anterior septum and apex, resulting in a "ballooning" appearance. However, it has rarely been reported in patients undergoing spinal surgery. CASE PRESENTATION: We report a case of severe stress cardiomyopathy in a scoliosis patient with pectus excavatum who underwent spinal corrective surgery. During the wake-up period, circulatory collapse occurred. After multidisciplinary consultation, the patient was diagnosed with stress cardiomyopathy. At last, she had a good prognosis after a series of treatments including ECMO. CONCLUSION: Stress cardiomyopathy is a reversible but uncommon condition. It can cause death if it is not diagnosed in time. Consequently, this report should improve the awareness of orthopedists and anesthesiologists for timely identification and management. For patients with potential risk factors, timely preoperative intervention should be performed to reduce the occurrence of stress cardiomyopathy.

BACKGROUND: Pectus excavatum, the most common chest wall deformity, is frequently treated with Nuss procedure. Here we will describe non-invasive procedure and analyze the variables associated vacuum bell therapy for patients with pectus excavatum. METHODS: Retrospective case-control study in a single center between July 2018 and February 2022, including patients with pectus excavatum treated with vacuum bell. Follow-up was continued to September 2022. The Haller index and Correction index was calculated before and after treatment to analysis the effectiveness of vacuum bell therapy. RESULTS: There were 98 patients enrolled in the treatment group, with 72 available for analysis, and the follow-up period ranged from 1.1 to 4.4 years (mean 3.3 years). When analyzing with the Haller Index, 18 patients (25.0%) showed excellent correction, 13 patients (18.1%) achieved good correction, and 4 patients (5.6%) had fair correction. The remaining patients had a poor outcome. Characteristics predicting a non-poor prognosis included initial age ≤ 11 years (OR = 3.94, p = 0.013) and patients with use over 24 consecutive months (OR = 3.95, p = 0.013). A total of 9 patients (12.5%) achieved a CI reduction below 10. Patients who started vacuum bell therapy at age > 11 had significantly less change compared to those who started at age ≤ 11 (P < 0.05). Complications included chest pain (5.6%), swollen skin (6.9%), chest tightness (1.4%) and erythema (15.3%). CONCLUSIONS: A certain percentage of patients with pectus excavatum can achieve excellent correction when treated with pectus excavatum therapy. Variables predicting better outcome including initial age ≤ 11 years both in HI and CI and vacuum bell use over 24 consecutive months in HI. In summary, pectus excavatum is an emerging non-invasive therapy for pectus excavatum and will be widely performed in a certain group of patients.

OBJECTIVE: This study aims to translate the Pectus Excavatum Evaluation Questionnaire(PEEQ) into Chinese, and to comprehensively assess subjective outcomes in quality of life of children with pectus excavatum. METHODS: The PEEQ was translated from English to Chinese as according to the PRO translation guidelines. Structural validity and reliability of the questionnaire were examined by validated factor analysis and Cronbach's alpha coefficient analysis respectively. RESULTS: The results of the validation factor analysis for the Chinese PEEQ parent's and child's questionnaires demonstrated that the fit indicators for each dimension met the required criteria. The overall Cronbach's alpha coefficient of parent's and child's questionnaires were 0.840 and 0.854. Both the item-level content validity index (I-CVI) and scale-level content validity index (S-CVI) of each sub-questionnaire were 1. CONCLUSION: The Chinese version of the PEEQ parent's questionnaire is suitable as a proxy assessment for patients with PE, but the child's questionnaire needs further adjustments.

BACKGROUND: Pectus excavatum repair is associated with significant discomfort, and pain is a primary contributor to postoperative hospital length of stay. Recent advances in postoperative pain control include the use of intercostal cryoablation techniques that may now make it possible to discharge patients on the day of surgery. Unnecessary variation in patient care and noncompliance with care bundles may be a factor in extended length of stay. The global aim of this quality improvement initiative was to successfully implement an enhanced recovery after surgery (ERAS) pathway on patients undergoing pectus excavatum repair. The SMART aim was to have a greater than 70% compliance for the perioperative bundle elements within 1 year of the pathway implementation. METHODS: Multiple Plan-Do-Study-Act (PDSA) cycles were designed to create and implement an ERAS pathway for patients undergoing a pectus bar insertion procedure. This multidisciplinary pathway was designed, managed, and implemented with key stakeholders from the Departments of Evidence Based Practice, Surgery, Anesthesiology, and Perioperative Nursing. Patient characteristics, outcomes, and compliance with elements of the pathway were measured for analysis for both the baseline and post-intervention groups with monthly automated reports. RESULTS: After implementation of the ERAS pathway, data on the first 50 patients showed a 90% compliance with the perioperative bundle elements. Mean length of stay was significantly decreased from 33 h (95% CI [28.76, 37.31]) to 18 h (95% CI [14.54, 21.70]). There were zero readmissions within 24 hours for patients who were discharged on the day of surgery. CONCLUSION: Employing a multidisciplinary approach in both planning and execution that standardized clinician practices and minimized unnecessary variation in patient care, an ERAS pathway for pectus bar insertion has been successfully established at our institution.

BACKGROUND: Pectus excavatum (PE) is a common congenital chest wall deformity with various associated health concerns, including psychosocial impacts, academic challenges, and potential cardiopulmonary effects. OBJECTIVE: This study aimed to investigate the cardiac consequences of right atrioventricular groove compression in PE using cardiac magnetic resonance imaging. MATERIALS AND METHODS: A retrospective analysis was conducted on 661 patients with PE referred for evaluation. Patients were categorized into three groups based on the degree of right atrioventricular groove compression (no compression (NC), partial compression (PC), and complete compression(CC)). Chest wall indices were measured: pectus index (PI), depression index (DI), correction index (CI), and sternal torsion. RESULTS: The study revealed significant differences in chest wall indices between the groups: PE, NC=4.15 ± 0.94, PC=4.93 ± 1.24, and CC=7.2 ± 4.01 (P<0.0001). Left ventricle ejection fraction (LVEF) showed no significant differences: LVEF, NC=58.72% ± 3.94, PC=58.49% ± 4.02, and CC=57.95% ± 3.92 (P=0.0984). Right ventricular ejection fraction (RVEF) demonstrated significant differences: RVEF, NC=55.2% ± 5.3, PC=53.8% ± 4.4, and CC=53.1% ± 4.8 (P≥0.0001). Notably, the tricuspid valve (TV) measurement on the four-chamber view decreased in patients with greater compression: NC=29.52 ± 4.6; PC=28.26 ± 4.8; and CC=24.74 ± 5.73 (P<0.0001). CONCLUSION: This study provides valuable insights into the cardiac consequences of right atrioventricular groove compression in PE and lends further evidence of mild cardiac changes due to PE.

BACKGROUND: Pectus excavatum (PEx) can cause cardiopulmonary limitations due to cardiac compression and displacement. There is limited data on electrocardiogram (ECG) alterations before and after PEx surgical repair, and ECG findings suggesting cardiopulmonary limitations have not been reported. The aim of this study is to explore ECG manifestations of PEx before and after surgery including associations with exercise capacity. METHODS: A retrospective review of PEx patients who underwent primary repair was performed. ECGs before and after surgical correction were evaluated and the associations between preoperative ECG abnormalities and cardiopulmonary function were investigated. RESULTS: In total, 310 patients were included (mean age 35.1 ± 11.6 years). Preoperative ECG findings included a predominant negative P wave morphology in V1, and this abnormal pattern significantly decreased from 86.9% to 57.4% (p < 0.001) postoperatively. The presence of abnormal P wave amplitude in lead II (>2.5 mm) significantly decreased from 7.1% to 1.6% postoperatively (p < 0.001). Right bundle branch block (RBBB) (9.4% versus 3.9%, p < 0.001), rsr' patterns (40.6% versus 12.9%, p < 0.001), and T wave inversion in leads V1-V3 (62.3% vs 37.7%, p < 0.001) were observed less frequently after surgery. Preoperative presence of RBBB (OR = 4.8; 95%CI 1.1-21.6) and T wave inversion in leads V1-3 (OR = 2.3; 95%CI 1.3-4.2) were associated with abnormal results in cardiopulmonary exercise testings. CONCLUSION: Electrocardiographic abnormalities in PEx are frequent and can revert to normal following surgery. Preoperative RBBB and T wave inversion in leads V1-3 suggested a reduction in exercise capacity, serving as a marker for the need for further cardiovascular evaluation of these patients.

BACKGROUND: Our institution recently transitioned from paravertebral nerve blocks (PVBs) to intercostal nerve cryoablation (INC) for pain control following minimally invasive repair of pectus excavatum (MIRPE). This study aimed to determine how INC affected the operative time, length of stay, complication rates, inpatient opioid use, and outpatient prescription of opioids at a single center. METHODS: A retrospective review was performed at a single pediatric referral center of all patients who underwent MIRPE between 2018 and 2023. Patient demographics, operative details, and perioperative course were collected. The use of INC versus PVB was recorded. Univariate analyses were performed using Wilcoxon rank sum tests for continuous variables and chi-squared tests for categorical variables. RESULTS: 255 patients were included with a median age of 15 years, median BMI of 18.50 kg/m2, and median Haller index of 4.40. INC was utilized in 41% (105/255), and 59% (150/255) received PVB. The two groups did not differ significantly in BMI, Haller index, or complications, though the INC patients were older by 1 year (15.0 vs. 16.0, p = 0.034). INC was associated with an increased operative time (INC: 92 min vs. PVB: 67 min, p < 0.001), decreased length of stay (3 vs. 4 days, p = < 0.001), more than twofold decrease in inpatient opioids per day (INC: 16 MME vs. PVB: 41 MME, p < 0.001), and a fourfold decrease in the amount of opioids prescribed at discharge (INC: 90 MME vs. PVB: 390 MME, p < 0.001). CONCLUSION: INC after MIRPE significantly decreased both the inpatient opioid utilization and our outpatient prescribing practices while also decreasing our overall length of stay without increasing complications. LEVEL OF EVIDENCE: Level III.

PURPOSE: The study aimed to compare spinal posture, mobility, and position sense in adolescents with pectus excavatum (PE), pectus carinatum (PC), and healthy control (HC). METHODS: 22 with PE, 22 with PC, and 21 HC were included in the study. The spinal posture (thoracic kyphosis, lumbar lordosis, pelvic tilt, thoracic, lumbar, pelvic lateral tilt angles) and mobility (thoracic, lumbar, hip/sacral, and overall, in the sagittal and frontal plane) with the spinal mouse, and spinal position sense (repositing errors) with the inclinometer were assessed. RESULTS: The thoracic kyphosis angle of PE and PC was higher than in HC (p < 0.001; p = 0.001). Hip/sacral mobility in the sagittal plane was lower in the PE and PC than control, respectively (p < 0.001; p < 0.001). Overall sagittal spinal mobility (p:0.007) and hip/sacral mobility in the frontal plane (p:0.002) were lower in the PC than in HC. Overall frontal spinal mobility was lower in the PE and PC than in HC (p:0.002; p:0.014). The PE and PC repositing errors were higher (p < 0.001; p:0.014). CONCLUSION: The study found that adolescents with PE and PC had decreased spinal mobility, spinal alignment disorders, and a decline in spinal position sense. It is important not to overlook the spine during physical examinations of adolescents with chest wall deformities. In clinical practice, we suggest that adolescents with chest deformities should undergo a spine evaluation and be referred for physical therapy to manage spinal disorders.

BACKGROUND: Sternal cleft (SC), a rare thoracic malformation, is associated with pectus excavatum (PE) in 2.6-5% of cases. It remains unclear if these conditions are congenitally linked or if SC repair triggers PE. To investigate the potential higher frequency of PE in SC cases, we conducted a retrospective study of our SC patients. METHODS: We assessed PE incidence, progression, and management in SC patients treated at our institute from 2006 to 2022. When available, we collected pre-SC repair CT scan data, calculating the Haller Index (HI) and Correction Index (CI) and compared them to a selected control group. RESULTS: Among 8 SC patients, 7 had concomitant PE (87.5%), varying in severity. PE management ranged from observation to thoracoplasty, depending on its degree. We observed a significant pre-operative CI difference between SC and control group patients (p < 0.00001). In the last two SC repair cases, we attempted concurrent PE prevention or treatment. CONCLUSION: Our findings suggest an underestimated association between PE and SC in the existing literature. SC patients may exhibit a predisposition to PE from birth, which may become more apparent with growth after SC repair. Consequently, PE prevention or treatment should be considered during SC repair procedures.

PURPOSE: The utility of pulmonary function testing (PFT) in pectus excavatum (PE) has been subject to debate. Although some evidence shows improvement from preoperative to postoperative values, the clinical significance is uncertain. A high failure-to-completion rate for operative PFT (48%) was identified in our large institutional cohort. With such a high non-completion rate, we questioned the overall utility of PFT in the preoperative assessment of PE and sought to evaluate if other measures of PE severity or cardiopulmonary function could explain this finding. METHODS: Demographics, clinical findings, and results from cardiac MRI, PFT (spirometry and plethysmography), and cardiopulmonary exercise tests (CPET) were reviewed in 270 patients with PE evaluated preoperatively between 2015 and 2018. Regression modeling was used to measure associations between PFT completion and cardiopulmonary function. RESULTS: There were no differences in demographics, symptoms, connective tissue disorders, or multiple indices of pectus severity and cardiac deformation in PFT completers versus non-completers. While regression analysis revealed higher RVEF, LVEF, and LVEF-Z scores, lower RV-ESV/BSA, LV-ESV/BSA, and LV-ESV/BSA-Z scores, and abnormal breathing reserve in PFT completers vs. non-completers, these findings were not consistent across continuous and binary analyses. CONCLUSIONS: We found that PFT completers were not significantly different from non-completers in most structural and functional measures of pectus deformity and cardiopulmonary function. Inability to complete PFT is not an indicator of pectus severity.

PURPOSE: The current standard method for pectus excavatum (PE) repair is the Nuss procedure. One major postoperative complication is the displacement of the implanted metal bar, which is used to remodel the chest wall. Blocking the possible ways that the bar can be displaced with the use of stabilizers and peri/intracostal sutures has reduced the incidence of bar displacement. Despite the modifications, bar dislocation is often reported. We adopted the medial position stabilizer placement method and imposed no postoperative restrictions. In this study, we analyzed the bar dislocation rate with this modification and concurrent postoperative full activity. METHODS: Nuss procedure modification where stabilizers are placed bilaterally in the medial location was done on patients irrespective of age and Haller index greater than 3.25. A single bar was used for all patients. Cryoanalgesia was performed on every patient. No postoperative restrictions were imposed on the patients. Full immediate activities, including sports, were allowed. RESULTS: 114 patients (103 male, 11 female) were analyzed from 2016 to 2023. The median age was 15 years old. There was zero incidence of bar displacement. The combined incidence of other postoperative complications was 4%: 2 wound infections and 2 hematoma formations, both needing incision and drainage. CONCLUSION: Bilateral medial stabilizer placement resulted in no incidence of bar dislocation. Return to immediate full activities after the Nuss procedure did not appear to increase the incidence of bar displacement if stabilizers were placed medially.

BACKGROUND: Recent data highlight the internet's pivotal role as the primary information source for patients. In this study, we emulate a patient's/caregiver's quest for online information concerning chest deformities and assess the quality of available information. METHODS: We conducted an internet search using combination of the terms "pectus excavatum," "pectus excavatum surgery," "funnel chest," "pectus excavatum repair" and identified the first 100 relevant websites from the three most popular search engines: Google, Yahoo, and Bing. These websites were evaluated using the modified Ensuring Quality Information for Patients (EQIP) instrument. RESULTS: Of the 300 websites generated, 140 (46.7%) were included in our evaluation after elimination of duplicates, non-English websites, and those targeting medical professionals. The EQIP scores in the final sample ranged from 8 to 32/36, with a median score of 22. Most of the evaluated websites (32.8%) originated from hospitals, yet none met all 36 EQIP criteria. DISCUSSION: None of the evaluated websites pertaining to pectus excavatum achieved a flawless "content quality" score. The diverse array of websites potentially complicates patients' efforts to navigate toward high-quality resources. Barriers in accessing high-quality online patient information may contribute to disparities in referral, patient engagement, treatment satisfaction, and overall quality of life.

Keratoconus is a bilateral ocular condition characterized by irregularities and the thinning of the cornea. Decreased central corneal thickness is a hallmark of the condition, and numerous genes have played a role in altering corneal thickness and the subsequent development of keratoconus. Variants in the structural and regulatory genes of the extracellular matrix have been highly associated with keratoconus, as well as with pectus excavatum, a chest wall deformity commonly seen in connective tissue disorders. This report describes a patient with a c.1720-11T>A intronic variant in the collagen-encoding gene, COL5A1, who was diagnosed with early-onset keratoconus and demonstrated a significant pectus excavatum. This report associates a COL5A1 variant with these seemingly unrelated phenotypic associations, further advancing the literature on the topic.

BACKGROUND: Pectus excavatum (PE) is the most common congenital chest wall deformity, whose cardiopulmonary consequences are controversial. PE surgery is in our experience usually performed for aesthetic reasons. OBJECTIVES: The aim of this study was to evaluate the impact of PE on respiratory function and exercise capacity in patients with PE before patient-specific silicone implant correction. METHODS: This monocentric prospective study conducted at Toulouse University Hospital included sixty patients scheduled for custom-made silicone implants correction. Respiratory function (pulmonary function tests (FPTs)) and exercise capacity (VO2 max) were measured before surgery. RESULTS: Before surgery, no (0/60) restrictive lung disease was detected, with a mean total lung capacity (TLC) of 98.5% of predicted value (IC 95%; 80.4-137). Median VO2 max (n=56) was normal (89% predicted), with no cardiac limitation. CONCLUSION: In this cohort, PE had no impact on respiratory function nor exercise capacity. In patients without cardiac or respiratory effects of PE, silicone implants should be considered the preferred approach as it adequately addressed patients' main complaint of low self-esteem.

Background: Right ventricular failure (RVF) is a significant cause of morbidity and mortality in patients with a left ventricular assist device (LVAD). This study is aimed to investigate the influence of a pectus excavatum on early and late outcomes, specifically RVF, following LVAD implantation. Methods: A retrospective study was performed, that included patients with a HeartMate 3 LVAD at our tertiary referral center. The Haller index (HI) was calculated using computed tomography (CT) scan to evaluate the chest-wall dimensions. Results: In total, 80 patients (median age 57 years) were included. Two cohorts were identified: 28 patients (35%) with a normal chest wall (HI < 2.0) and 52 patients (65%) with pectus excavatum (HI 2.0-3.2), with a mean follow-up time of 28 months. Early ( ≤ 30 days) RVF and early acute kidney injury events did not differ between cohorts. Overall survival did not differ between cohorts with a hazard ratio (HR) of 0.47 (95% confidence interval (CI): 0.19-1.19, p = 0.113). Late ( > 30 days) recurrent readmission for RVF occurred more often in patients with pectus excavatum (p = 0.008). The onset of late RVF started around 18 months after implantation and increased thereafter in the overall study cohort. Conclusions: Pectus excavatum is observed frequently in patients with a LVAD implantation. These patients have an increased rate of readmissions and late RVF. Further investigation is required to explore the extent and severity of chest-wall abnormalities on the risk of RVF.
