Abstract
Oscillometry has been around for almost 70 years, but there are still many unknowns. The test is performed during tidal breathing and is therefore free from patient-dependent factors that could influence the results. The Forced Oscillation Technique (FOT), which requires minimal patient cooperation, is gaining ground, particularly with elderly patients and children. In pulmonology, it is a valuable tool for assessing obstructive conditions (with a distinction between central and peripheral obstruction) and restrictive disorders (intrapulmonary and extrapulmonary). Its sensitivity allows the assessment of bronchodilator and bronchoconstrictor responses. Different lung diseases show different patterns of changes in FOT, especially studied in asthma and chronic obstructive pulmonary disease. Because of these differences, many studies have analysed the usefulness of this technique in different areas of medicine. In this paper, the authors would like to present the basics of oscillometry with the areas of its most recent clinical applications.

Lu YS, Chou CC, Tseng YH, Lin KL, Chen CH, Chen YJ. Cardiopulmonary functional capacity in Taiwanese children with ventricular septal defects. Pediatr Neonatol 2023; 64:554-561. [PMID: 37003956 DOI: 10.1016/j.pedneo.2023.02.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/04/2022] [Revised: 12/23/2022] [Accepted: 02/09/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Children with ventricular septal defects (VSDs) are considered to have no difference in cardiopulmonary functional capacity with healthy children of the same age; however, studies have shown contradictory findings. The aim of this study was to assess whether Taiwanese children with VSDs exhibited cardiopulmonary deficits. METHODS This is a retrospective cohort study with the data collected from January 2010 to December 2021. All patients and controls (age-, sex-, and body mass index -matched) underwent cardiopulmonary exercise testing (CPET) and pulmonary function test. RESULTS In total, 157 VSD patients (80 patients with surgically closed VSDs, 77 patients with unrepaired VSDs) and 157 healthy controls were recruited. Pulmonary function test showed significant among-group differences in maximal voluntary ventilation (MVV) (p = 0.015). The surgically closed group had lower MVV compared to the control group. Regarding CPET, we found VSD patients had lower peak oxygen uptake than the controls (surgically closed group: 30.84 ± 6.27 ml/kg/min; unrepaired group: 32.00 ± 5.95 ml/kg/min; control group: 36.76 ± 6.50 ml/kg/min, p < 0.001). There was also significant among-group differences in aerobic capacity (surgically closed group: 21.20 ± 4.39 ml/kg/min; unrepaired group: 21.68 ± 4.47 ml/kg/min; control group: 26.25 ± 4.33 ml/kg/min, p < 0.001). In addition, the surgically closed group had lower heart rate average at anaerobic threshold than the control group (surgically closed group: 138.11 ± 16.42 bpm; control group: 145.78 ± 15.53 bpm, p = 0.002). CONCLUSION Taiwanese children with VSD, whether surgically closed or not, have poorer cardiopulmonary performance than age-matched healthy children, and the results of the surgically closed group were even worse.

Practice Patterns in the Management of Pressure Restrictive Perimembranous Ventricular Septal Defects: A Multinational Survey. Pediatr Cardiol 2022; 44:845-854. [PMID: 36538052 DOI: 10.1007/s00246-022-03073-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Accepted: 12/05/2022] [Indexed: 12/24/2022]
Abstract
Indications for the closure of pressure restrictive perimembranous ventricular septal defects (pmVSD) are not well established in the pediatric population. We sought to assess practice variability among pediatric cardiologists in the United States (US), Canada, Australia, and New Zealand. A survey ascertaining practice patterns, including case vignettes with incremental progression of disease severity, was designed and administered through representative professional cardiac organizations and email listservs in the designated countries. Among the 299 respondents, 209 (70.0%) were from the US, 65 (21.7%) were from Canada and 25 (8.3%) were from Australia and New Zealand. Indications for pressure restrictive pmVSD closure included the presence of left ventricular (LV) dilation for 81.6% (244/299) (defined as z-score ≥ 2 for 59.0% (144/244) and ≥ 3 for 40.2% (98/244)) and significant pulmonary-systemic flow ratio (QP:QS) for 71.2% (213/299) [defined as ≥ 1.5:1 for 36.2% (77/213) and ≥ 2 for 62% (132/213)]. US pediatric cardiologists elected to close restrictive pmVSD at lower LV z-score and QP:QS ratio cut-offs (p-value 0.0002 and 0.013, respectively). In a case vignette, 63.6% (173/272) chose to intervene if there was right coronary cusp prolapse with stable mild aortic regurgitation. Of the remaining cardiologists, 93% (92/99) intervened if the aortic regurgitation was progressive (from trivial to mild). Commonly identified indications with variable thresholds for closure of pressure restrictive pmVSDs included the presence or progression of LV dilation, significant volume loading, and aortic valve prolapse with regurgitation. US pediatric cardiologists may have a lower threshold for pmVSD closure.

Abstract
Decision-making in congenital cardiac care, although sometimes appearing simple, may prove challenging due to lack of data, uncertainty about outcomes, underlying heuristics, and potential biases in how we reach decisions. We report on the decision-making complexities and uncertainty in management of five commonly encountered congenital cardiac problems: indications for and timing of treatment of subaortic stenosis, closure or observation of small ventricular septal defects, management of new-onset aortic regurgitation in ventricular septal defect, management of anomalous aortic origin of a coronary artery in an asymptomatic patient, and indications for operating on a single anomalously draining pulmonary vein. The strategy underpinning each lesion and the indications for and against intervention are outlined. Areas of uncertainty are clearly delineated. Even in the presence of "simple" congenital cardiac lesions, uncertainty exists in decision-making. Awareness and acceptance of uncertainty is first required to facilitate efforts at mitigation. Strategies to circumvent uncertainty in these scenarios include greater availability of evidence-based medicine, larger datasets, standardised clinical assessment and management protocols, and potentially the incorporation of artificial intelligence into the decision-making process.

Abstract
Cardiovascular disease remains the number one cause of death in Americans. It is no secret that exercise mitigates this risk. Exercise and regular physical activity are beneficial for physical health including aerobic conditioning, endurance, strength, mental health, and overall improved quality of life. Unfortunately, today many children and adolescents are sedentary, lacking the recommended daily amount of physical activity, leading to higher rates of obesity, cardiovascular disease, stroke, diabetes, anxiety, and depression. Given this rising concern, the World Health Organization launched a 12-year plan to improve physical activity in children and adolescents by reducing the inactivity rate by 15% in the world. How does this apply to children and adolescents with acquired or congenital heart disease?.

Exercise Capacity in Children and Adolescents With Congenital Heart Disease: A Systematic Review and Meta-Analysis. Front Cardiovasc Med 2022; 9:874700. [PMID: 35600470 PMCID: PMC9114479 DOI: 10.3389/fcvm.2022.874700] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Accepted: 03/29/2022] [Indexed: 11/18/2022] Open
Abstract
Background Congenital heart disease (CHD) entails structural defects in the morphogenesis of the heart or its main vessels. Analyzing exercise capacity of children and adolescents with CHD is important to improve their functional condition and quality of life, since it can allow timely intervention on poor prognostic factors associated with higher risk of morbidity and mortality. Objective To describe exercise capacity in children and adolescents with CHD compared with healthy controls. Methods A systematic review was carried out. Randomized clinical trials and observational studies were included assessing exercise capacity through direct and indirect methods in children and adolescents between 5 and 17 years-old. A sensitive analysis was performed including studies with CHD repaired participants. Additionally, it was sub-analyzed by age range (< and ≥ 12 years old). Two independent reviewers analyzed the studies, extracted the data, and assessed the quality of the evidence. Results 5619 articles were found and 21 were considered for the review. Eighteen articles used the direct exercise capacity measurement method by cardiopulmonary exercise test (CPET). The CHD group showed significant differences in peak oxygen consumption (VO2peak) with a value of −7.9 ml/Kg/min (95% CI: −9.9, −5.9, p = 0.00001), maximum workload (Wmax) −41.5 (95% CI: −57.9, −25.1 watts, p = 0.00001), ventilatory equivalent (VE/VCO2) slope 2.6 (95% CI: 0.3, 4.8), oxygen pulse (O2 pulse)−2.4 ml/beat (95% CI: −3.7, −1.1, p = 0.0003), and maximum heart rate (HRmax) −15 bpm (95% CI: −18, −12 bpm, p = 0.00001), compared with healthy controls. Adolescents (≥ 12 yrs) with CHD had a greater reduction in VO2peak (−10.0 ml/Kg/min (95% CI: −12.0, −5.3), p < 0.00001), Wmax (−45.5 watts (95% CI: −54.4, −36.7), p < 0.00001) and HRmax (−21 bpm (95% CI: −28, −14), p<0.00001). Conclusion Suffering CHD in childhood and adolescence is associated with lower exercise capacity as shown by worse VO2peak, Wmax, VE/VCO2 slope, O2 pulse, and HRmax compared with matched healthy controls. The reduction in exercise capacity was greater in adolescents. Systematic Review Registration www.crd.york.ac.uk/prospero/display_record.php?RecordID=208963, identifier: CRD42020208963.

BMC Cardiovasc Disord 2021; 21:512.

Abstract
OBJECTIVE To investigate the midterm effect of exercise capacity and quality of life (QoL) of adult patients who underwent transthoracic device closure of ventricular septal defects (VSDs) and explore the gap in the quality of life and cardiopulmonary function between those patients and healthy people. METHODS From January 2010 to January 2015, 58 adult patients who underwent transthoracic device closure of VSD and 60 healthy people matched for age and sex were selected and analyzed. Echocardiography and exercise capacity tests were performed, and the MOS 36-item short-form health survey (SF-36) was used to investigate the changes in QoL. RESULTS Fifty-five patients completed the study. At the 1-year and 5-year follow-ups, the patients' left ventricular end-systolic and end-diastolic diameters were smaller than those preoperatively, but the difference was not statistically significant. In the QoL survey, the patients' scores after treatment showed a trend of improvement, and the improvement effect was not transient. After VSD closure, the difference in QoL between the patients and the control group was significantly reduced. However, in the exercise capacity test, the patients' results were still worse than those of the controls. CONCLUSION Transthoracic device closure of VSDs is significant in improving adult patients' QoL at the midterm follow-up, reflected in their physical and psychological fields. However, they are still unable to achieve normal levels of peak exercise ability. Therefore, further exploration and interventions are worth considering.

Abstract
Background Ventricular septal defects (VSD), when treated correctly in childhood, are considered to have great prognoses, and the majority of patients are discharged from follow‐up when entering their teens. Young adults were previously found to have poorer functional capacity than healthy peers, but the question remains whether functional capacity degenerates further with age. Methods and Results A group of 30 patients with surgically closed VSDs (51±8 years) with 30 matched, healthy control participants (52±9 years) and a group of 30 patients with small unrepaired VSDs (55±12 years) and 30 matched control participants (55±10 years) underwent cardiopulmonary exercise testing using an incremental workload protocol and noninvasive gas measurement. Peak oxygen uptake was lower in participants with closed VSDs than matched controls (24±7 versus 34±9 mL/min per kg, P<0.01) and with unrepaired VSDs than matched controls (26±5 versus 32±8 mL/min per kg, P<0.01). Patients demonstrated lower oxygen uptake from exercise levels at 20% of maximal workload compared with respective control groups (P<0.01). Peak ventilation was lower in patients with surgically closed VSDs than control participants (1.0±0.3 versus 1.4±0.4 L/min per kg, P<0.01) but similar in patients with unrepaired VSDs and control participants (P=0.14). Exercise capacity was 29% lower in older patients with surgically closed VSDs than healthy peers, whereas younger patients with surgically closed VSDs previously demonstrated 18% lower capacity compared with peers. Older patients with unrepaired VSDs reached 21% lower exercise capacity, whereas younger patients with unrepaired VSDs previously demonstrated 17% lower oxygen uptake than healthy peers. Conclusions Patients with VSDs demonstrate poorer exercise capacity than healthy peers. The difference between patients and control participants increased with advancing age—and increased most in patients with operated VSDs—compared with previous findings in younger patients. Results warrant continuous follow‐up for these simple defects.
