Good quality of life correlates with a good exercise capacity in daily life in patients with tetralogy of Fallot (ToF). Patients after correction of ToF usually develop residual defects such as pulmonary regurgitation or stenosis of variable severity. However, the importance of different hemodynamic parameters and their impact on exercise capacity is unclear. We investigated several hemodynamic parameters measured by cardiovascular magnetic resonance (CMR) and echocardiography and evaluated which parameter has the most pronounced effect on maximal exercise capacity determined by cardiopulmonary exercise testing (CPET). 132 patients with ToF-like hemodynamics were tested during routine follow-up with CMR, echocardiography and CPET. Right and left ventricular volume data, ventricular ejection fraction and pulmonary regurgitation were evaluated by CMR. Echocardiographic pressure gradients in the right ventricular outflow tract and through the tricuspid valve were measured. All data were classified and correlated with the results of CPET evaluations of these patients. The analysis was performed using the Random Forest model. In this way, we calculated the importance of the different hemodynamic variables related to the maximal oxygen uptake in CPET (VO%predicted). Right ventricular pressure showed the most important influence on maximal oxygen uptake, whereas pulmonary regurgitation and right ventricular enddiastolic volume were not important hemodynamic variables to predict maximal oxygen uptake in CPET. Maximal exercise capacity was only very weakly influenced by right ventricular enddiastolic volume and not at all by pulmonary regurgitation in patients with ToF. The variable with the most pronounced influence was the right ventricular pressure. [ABSTRACT FROM AUTHOR]

Objective Multiple studies have demonstrated the predictive value of arterial stiffness parameters like augmentation index (AIx) for cardiovascular events, the onset of hypertension, and the progression of heart failure. There is evidence that arterial stiffness is increased in some diagnostic subgroups of patients with congenital heart defects (CHD). This study aims to investigate AIx in a large cross-sectional cohort of patients with CHD. Patients and methods We prospectively examined 1125 consecutive patients with various congenital heart defects (27.3 ± 12.1 years, 464 female) referred for routine cardiopulmonary exercise testing (CPET) in our institution, and 322 healthy volunteers (29.4 ± 18.4 years, 165 female). AIx was estimated in supine position using the oscillometric Vicorder device (SMT medical, Würzburg, Germany). Afterward patients performed a CPET. Results In multivariable regression, presence of a CHD emerged as independent risk factor for higher AIx (p < .001). AIx was also higher in older (p < .001), smaller (p < .001) and heavier (p < .001) patients and in females (p = .008). Patients with aortic stenosis (p < .001), Tetralogy of Fallot (p < .001), transposition of the great arteries after atrial switch (p < .001) or Rastelli procedure (p = .013) and after Fontan procedure (p = .002) had higher AIx. Higher peak oxygen uptake (p < .001) and an ACE-inhibitor (p = .088) were associated with a lower AIx. Conclusions AIx is increased in patients with CHD. Several diagnostic subgroups are at risk. A better understanding of pathophysiologic mechanisms, genetic predisposition, the role of surgical aortic scars or implanted conduits/patches and medication is needed to define the value of AIx for further cardiovascular risk assessment in this cohort.

Abstract: Objective: This study aimed to compare situational and trait anxiety levels in patients with congenital heart disease (CHD) with that in healthy controls and to investigate their correlation to the perceived health status. Patients and methods: From November 2007 to December 2009 in total 879 patients (405 female, 15–71years) with various CHD and 40 healthy controls completed the State-Trait Anxiety Inventory (STAI) to assess state and trait anxiety, the depression scaling instrument CES-D, and the health-related quality of life questionnaire SF-36. Results: In patients with CHD no increased anxiety as a trait could be found (Mann–Whitney Utest, p=.186). Only situational anxiety in the setting of an outpatient department in a tertiary center was increased compared to healthy controls (Mann–Whitney U test, p=.004). Anxiety was closely related to depression and to all of the nine SF-36 dimensions (r=−.149 to r=−.745, p<.001). Conclusions: In general, patients with CHD show a rather normal anxiety pattern compared to healthy controls. These symptoms of anxiety were strongly correlated with the perceived health status. Only situational anxiety levels at the hospital are increased and still remain an important challenge for doctors and psychologists. [Copyright &y& Elsevier]

Objective Health-related quality of life questionnaires are frequently used to involve patients' impressions and feelings in the outcome evaluation. In patients with congenital heart disease (CHD) methodological heterogeneities, assessment in different age and diagnostic groups led to controversial findings. This study aims to give a comprehensive answer to the health-related quality of life in patients with CHD. Patients and methods From July 2001 to June 2013, 2360 patients (1058 female, 28.6±11.2-years, range 14-75-years) with various kinds of CHD underwent a quality of life assessment with the SF-36 questionnaire and underwent a cardiopulmonary exercise test as part of their routine follow-up. Results Physical component summary score (PCS) develops from 96.1 %predicted in patients younger than 20-years, to 96.2 %predicted in patients aged 20 to 30-years, 92.3 %predicted in patients aged 30 to 40-years, and 92.6 %predicted in patients 40-years or older (r=-.114; p<.001). The decline was more prominent in the mental component summary score (MCS) declining from 104.1 %predicted in patients younger than 20years, to 103.4 %predicted, 99.9 %predicted, and 97.5 %predicted (r=-.132; p<.001). Exercise capacity was impaired with 80.1±23.0 %predicted and also declined slowly with age (r=-.084; p<.001). Conclusions Health-related quality of life in patients with CHD is progressively reduced in older age-groups. The decline is small, but more prominent in the mental components. This should be considered in the interpretation of studies, and strategies have to be developed to reduce this effect in future. [ABSTRACT FROM AUTHOR]
