Tetralogy of Fallot (ToF) is the most common cyanotic congenital heart disease and the population of ToF repair survivors is growing rapidly. Adults with repaired ToF develop late complications. The aim of this study was to describe and analyze long-term follow-up of patients with repaired ToF. This is a retrospective cohort study. Consecutive 83 patients with repaired ToF who did not undergo pulmonary valve replacement were included. Mean age of all patients was 30.5 ± 10.7. There were 49 (59%) male. Patients were divided into two groups according to the time since the repair (< 25 years and ≥ 25 years). The electrocardiographic (ECG), cardiopulmonary exercise testing (CPET), echocardiographic and cardiac magnetic resonance (CMR) data were reviewed retrospectively. In CPET values were not significantly different in the two groups. In CMR volumes of left and right ventricles were not significantly different in the two groups. There were no differences between the groups in ventricular ejection fraction, mass of ventricles, or pulmonary regurgitation fraction. Among all the patients, ejection fraction and left and right ventricle mass, indexed pulmonary regurgitation volume measured by CMR did not correlate with the time since repair. In ECG among all the patients, ejection fraction of the RV, measured in CMR, negatively correlated with QRS duration (r = − 0.43; p < 0.001). There was a positive correlation between QRS duration and end diastolic volume of the RV (r = 0.30; p < 0.02), indexed end diastolic volume of the RV (r = 0.29; p = 0.04), RV mass (r = 0.36; p < 0.001) and left ventricle mass (r = 0.26; p = 0.04). Long-term survival and clinical condition after surgical correction of ToF in infancy is generally good and the late functional status in ToF – operated patients could be excellent up to 25 years after the repair. QRS duration could be an utility and easy factor to assessment of right ventricular function. The study protocol was approved by the local Ethics Committee. Each participant provided informed consent to participate in the study (license number 122.6120.88.2016 from 28.04.2016).
Background: Despite the low early mortality of Fontan procedures, Fontan patients are prone to various cardiac and extra-cardiac complications in the long term. This may influence patient perception of their health and outcome. The aim of the study was to assess the relationship of multi-organ complications and physical efficiency with self-reported health-related quality of life (QOL) in adult Fontan patients. Methods: Quality of life was assessed with the Short Form-36 questionnaire. Laboratory tests were done together with echocardiography, plethysmography, and cardiopulmonary exercise test. Results: The QOL was poorer in patients than in control subjects. The physical characteristics of patients correlated with dynamic ventilatory parameters, heart rate at the peak of exercise, alanine aminotransferase and albumin level. Conclusions: Liver impairment and chronotropic incompetence during exercise are associated with poor QOL in patients after Fontan procedure. These patient hepatic, pulmonary and cardiac functions should be carefully monitored.

Investigate the effects of left and right ventricular function and severity of pulmonary valve regurgitation, quantified by cardiac magnetic resonance (CMR), on exercise tolerance in adult patients who underwent ToF repair at a young age. This is a retrospective cohort study of 52 patients after ToF surgery and 33 age- and sex-matched healthy volunteers. CMR and cardiopulmonary exercise testing (CPET) were performed on all patients; CPET was performed on control subjects. The main finding of CPET was a severe decrease in oxygen uptake at peak exercise VO2peak in TOF patients. The patients were characterized also by lower pulse O2peak and heart rate at peak exercise. Ejection fraction of the right and left ventricles was correlated (r=0,32; p=0,03). Left ventricle ejection fraction was negatively correlated with right ventricular volumes (r=-0,34; p=0,01) and right ventricular mass (r=-046; p<0,00). Right ventricular mass was positively correlated with left ventricular variables (left ventricle end diastolic volume, r=0,43; p=0,002; left ventricle end systolic volume, r=0,54; p<0,00) as was VO2peak: LVEDV (r=0,38; p=0,01); LVESV (r=0,33; p=0,03) and LV mass (r=0,42; p=0,006). Exercise intolerance in adults with repaired ToF is markedly depressed. The decreased exercise capacity is correlated with impaired RV function and may be associated also with LV dysfunction, which suggests right-to-left ventricular interaction.

Introduction Observations of patients after repair of tetralogy of Fallot (ToF) indicate good correction results and long-term survival. Few papers have been published in which the quality of life (QoL) of this population has been assessed. Aim To evaluate QoL in adults with repaired ToF....
Background Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital cardiac anomaly which requires surgical treatment, which improves left ventricular function and clinical outcomes. The definitive diagnosis of ALCAPA is based on coronary angiography, however, noninvasive visualization of the origin of the coronary artery is often helpful in the diagnosis of ALCAPA. Objectives The purpose of this study was to evaluate noninvasive techniques for the diagnosis of ALCAPA, and present the clinical outcomes in adults after surgical correction of ALCAPA. Methods Medical charts of five patients with ALCAPA treated at the John Paul II Hospital in Cracow between 2004 and 2012 were analyzed retrospectively. Noninvasive imaging techniques were used to visualize coronary vessels preoperatively. Patients were followed one year after the operation with echocardiograms and assessment of the New York Heart Association functional class. Results Computed tomography showed ALCAPA in four patients. Magnetic resonance imaging showed abnormal left ventricle remodeling suggestive of ischemia of the anterior cardiac wall. Myocardial perfusion imaging revealed ischemia of the middle and periapical segments of the anterior and anterolateral wall of the left ventricle in two patients. Postoperatively, patients had symptomatic improvement, but there was no statistically significant difference in mean ejection fraction. Conclusions Noninvasive techniques can be used to visualize the origin of the coronary arteries and characterize their morphology. Long-term follow-up of adult patients after surgical correction of ALCAPA is not well documented in the literature, but surgical treatment revealed beneficial short-term effects and symptoms relief.
