BACKGROUND: Safety events and technical success (TS) have been previously reported for aortic and pulmonary valvuloplasty, but a composite performance measure as a novel, patient-centered strategy has neither been developed nor been studied. This study aims to refine a procedural performance (PP) variable, a composite of TS and procedural safety, for isolated, standard-risk aortic and pulmonary valvuloplasty. METHODS: A multicenter review was performed using data from the Congenital Cardiac Catheterization Project on Outcomes registry. Data were collected for all cases of isolated balloon aortic and pulmonary valvuloplasty from 2014 through 2017. Patients were excluded if they were aged

Sports participation in patients with congenital heart disease is an evolving subject. The American Heart Association/American College of Cardiology released a set of guidelines that advise the type and level of sports participation based primarily on anatomical defects with secondary consideration given to hemodynamic effects. Recently, the European Association of Preventive Cardiology/European Society of Cardiology/Association for European Paediatric and Congenital Cardiology offered a contrasting approach to sports participation that is based on hemodynamic and electrophysiological profiles of each patient, regardless of anatomical consideration. These guidelines are drastically different in their approaches but do have some similarities. In this review, we compare both documents, focusing on the aim, population, classification of sports, and the methodology of making recommendations. This review aims to assist practicing cardiologists in integrating the available published data and recommendations when counseling patients for sports participation. [Display omitted] • Participation in sports is beneficial for most patients with CHD. • Recommendations in the AHA/ACC and EAPC/ESC/AEPC guidelines differ with respect to sports participation. • Both sets of recommendations are based mainly on expert opinion because high-quality evidence is lacking.

The Fontan operation has resulted in significant improvement in survival of patients with single ventricle physiology. As a result, there is a growing population of individuals with Fontan physiology reaching adolescence and adulthood. Despite the improved survival, there are long-term morbidities associated with the Fontan operation. Pulmonary complications are common and may contribute to both circulatory and pulmonary insufficiency, leading ultimately to Fontan failure. These complications include restrictive lung disease, sleep abnormalities, plastic bronchitis, and cyanosis. Cyanosis post-Fontan procedure can be attributed to multiple causes including systemic to pulmonary venous collateral channels and pulmonary arteriovenous malformations. This review presents the unique cardiopulmonary interactions in the Fontan circulation. Understanding the cardiopulmonary interactions along with improved recognition and treatment of pulmonary abnormalities may improve the long-term outcomes in this growing patient population. Interventions focused on improving pulmonary function including inspiratory muscle training and endurance training have shown a promising effect post-Fontan procedure. [Display omitted] • Pulmonary complications are common post-Fontan procedure, including restrictive lung disease, sleep abnormalities, PB, and cyanosis. • Pulmonary complications may contribute to Fontan circulatory failure by worsening pulmonary vascular resistance, hypoxia, and exercise capacity. • Respiratory muscle and exercise training may improve pulmonary function and exercise capacity after Fontan surgery.

The use of an oral positive expiratory pressure device (oPEP) with sniff breathing (Sniff-PEP) mimics biphasic ventilation. Biphasic ventilation increases pulmonary blood flow and cardiac output in Fontan patients. The aim of this study was to assess the effect of Sniff-PEP on Fontan flow velocities. A single-center, pilot, prospective study was carried out in 15 subjects with Fontan circulation enrolled to use the oPEP device for 1 month. Subjects were instructed on Sniff-PEP and to use the device for 10-15 min 3-4 times a day. Measurements of flow velocity and cardiac output were measured via echocardiogram and quality of life assessments were performed at baseline and 4-6 weeks later. The mean age at enrollment was 19.9 ± 8.7 years (age range of 10-37 years). 7 patients (47%) had dominant left ventricle and 8 (53%) had an open fenestration. There was a statistically significant increase in flow velocities in the hepatic vein from 27.5 ± 7.6 to 35.1 ± 11.3 cm/s (p = 0.003), left pulmonary artery from 51.6 ± 16.6 to 57.6 ± 21.1 cm/s (p = 0.01), and right pulmonary artery from 43.1 ± 14.2 to 45.8 ± 17.2 cm/s (p = 0.04). With chronic use, the mean fenestration gradient slightly decreased from 4.5 ± 1.6 to 4.1 ± 1.9 mmHg but the difference was not statistically significant (p = 0.14). oPEP device therapy increased flow velocity in several areas in the Fontan circulation with acute use. Further studies are needed to assess the effects long term.Clinical Trial Registration: URL: https://clinicaltrials.gov . Unique identifier: NCT03251742., (© 2024.
