previous studies have established an association between exercise intolerance and increased morbidity mortality in congenital heart disease patients. We aimed to clarify if is associated with poor outcome Fontan patients identify risk factors for mortality, transplantation, cardiac-related hospitalization.a total of 321 (57% male, mean age 20.9 ± 8.6 years) who underwent cardiopulmonary testing (CPET) at four major European centres 1997 2008 were included. During a median follow-up 21...

Dysfunction of valved conduits in the right ventricular outflow tract (RVOT) limits durability and enforces repeated surgical interventions. We report on our combined two-centre experience with percutaneous pulmonary valve implantation (PPVI). One hundred two patients RVOT dysfunction [median weight: 63 kg (54.2–75.9 kg), median age: 21.5 years (16.2–30.1 years), diagnoses: TOF/PA 61, TAC 14, TGA 9, other 10, AoS post-Ross-OP 8] were scheduled for PPVI since December 2006. Percutaneous was...

Previous studies have shown that older Fontan patients and those with an underlying morphologically right ventricle lower exercise capacity. We sought to assess the natural history of capacity after operation in individual patients, identify factors influencing rate decrease over time.We studied, longitudinally, 53 cardiopulmonary tests (average 3.2 +/- 1.1 for each patient). Age at first test was 14 6 years. Time intervals between ranged from 1 16 years (average, 7.7 4.0 years). The...

The aim of this study is to compare self-reported health-related quality-of-life (HRQoL) with the objective exercise performance in patients congenital heart disease (CHD) according diagnosis. 564 (255 females, 14–73 years) various CHD (62 shunt, 66 left obstruction, 33 PS/PR, 47 Ebstein, 96 Fallot, 98 TGA after atrial switch, 38 other TGA, 31 Fontan, 32 palliated/native cyanotic, 61 others) and a group 53 healthy controls (18 14–57 completed QoL questionnaire (SF-36) performed...

AimsWe compared flow and wall shear stress (WSS) patterns in the ascending aorta of individuals with either bicuspid aortic valve (BAV) or tricuspid (TAV) using four-dimensional cardiovascular magnetic resonance (4D-CMR). BAV are known to be associated dilation dissection aorta. However, cause vessel disease patients BAVs is unknown. Inborn connective tissue also secondary increased WSS because altered blood discussed as causes for can estimated non-invasively by 4D-CMR.

AimsPatients with congenital heart disease usually show diminished exercise capacity and quality of life. However, there is only little information about daily activity, a marker for lifestyle, capacity, the prevention arteriosclerosis. This study investigated life, their interaction univentricular physiology after total cavopulmonary connection (TCPC).

This study aims to evaluate the clinical outcome following total cavopulmonary connection (TCPC) and identify factors affecting early late outcome.Between May 1994 March 2015, 434 patients underwent TCPC with 50 lateral tunnels 374 extracardiac conduits. The outcome, exercise capacity liver examination results were retrospectively reviewed.Thirty-day survival was 98.2%, estimated rate at 15 years 92.3%. Freedom from tachyarrhythmia 91.0%. Other morbidities included bradyarrhythmia in 17,...

Abstract OBJECTIVES We aimed to determine the incidence of postoperative complete atrioventricular block, time recovery or permanent pacemaker implantation, and predictors for block after congenital heart surgery. METHODS Patients who underwent open surgery from January 2001 2024 were analyzed identified using a logistic regression model. RESULTS Among 9765 surgeries, 333 (3.4%) complicated by 193 patients (1.9%) implantation. The highest rates found in repair congenitally corrected...

This study aimed to evaluate the relationship between pulmonary artery size and venovenous collaterals during staged single ventricle reconstruction. Patients who underwent Fontan palliation 2003 2023 were reviewed. The index development of was determined. Furthermore, impact on in-hospital morbidities after procedure evaluated. A total 377 patients included. Median age at bidirectional cavopulmonary shunt connection 4.2 (3.3-6.2) months 2.1 (1.7-2.6) years, respectively. Venovenous observed...

Pulmonary hypertension (PH) is a condition of multiple aetiologies with underestimated prevalence and incidence. Indeed, despite access to modern therapies, pulmonary hypertensive vascular disease (PHVD) remains progressive, usually life-limiting condition, severely impacting on the patients' well-being. We herein provide practical, expert consensus recommendations initial diagnostic work-up, clinical management follow-up children adolescents PH/PHVD, including algorithm. The major topics...

Background: Percutaneous pulmonary valve implantation (PPVI) has become an important treatment of right ventricular outflow tract dysfunction. Studies directly comparing the long-term outcome PPVI with Melody to surgical replacement (SPVR) are lacking. Methods: All patients treated and SPVR between January 2006 December 2018 in our center were enrolled into a database investigated standard follow-up protocol. The current study compares outcomes means survival, reinterventions, infectious...
