Abstract
AIMS To assess the additional prognostic significance of echocardiographic parameters of subpulmonary left ventricular (LV) size and function in patients with a systemic right ventricle (SRV). METHODS AND RESULTS All adults with an SRV who underwent transthoracic echocardiography in 2010-18 at a large tertiary centre were identified. Biventricular size and function were assessed at the most recent examination. The study endpoint was all-cause mortality or heart/heart-lung transplantation. We included 180 patients, with 100 (55.6%) males, with a mean age of 42.4 ± 12.3 years, of whom 103 (57.2%) had undergone Mustard/Senning operations and 77 (42.8%) had congenitally corrected transposition of great arteries. Over 4.9 (3.8-5.7) years, 28 (15.6%) patients died and 4 (2.2%) underwent heart or heart-lung transplantation. Univariable predictors of the study endpoint included age, New York Heart Association functional Class III or IV, history of atrial arrhythmias, presence of a pacemaker or cardioverter defibrillator, high B-type natriuretic peptide, and echocardiographic markers of SRV and subpulmonary LV size and function. On multivariable Cox analysis of echocardiographic variables, indexed LV end-systolic diameter [ESDi; hazard ratio (HR) 2.77 (95% confidence interval, CI) 1.35-5.68, P = 0.01], LV fractional area change [FAC; HR 0.7 (95% CI 0.57-0.85), P = 0.002), SRV basal diameter [HR 1.66 (95% CI 1.21-2.29), P = 0.005], and SRV FAC [HR 0.65 (95% CI 0.49-0.87), P = 0.008] remained predictive of mortality or transplantation. On receiver-operating characteristic analysis, subpulmonary LV parameters performed better than SRV markers in predicting adverse events. CONCLUSION SRV basal diameter, SRV FAC, LV ESDi, and LV FAC are significantly and independently associated with mortality and transplantation in adults with an SRV. Accurate echocardiographic assessment of both SRV and subpulmonary LV is, therefore, essential to inform risk stratification and management.

Abstract
Background: Inherent to its geometry, echocardiographic imaging of the systemic right ventricle (RV) is challenging. Therefore, echocardiographic assessment of systemic RV function may not always be feasible and/or reproducible in daily practice. Here, we aim to validate the usefulness of a comprehensive range of 32 echocardiographic measurements of systemic RV function in a longitudinal cohort by serial assessment of their correlations with cardiac magnetic resonance (CMR)-derived systemic RV ejection fraction (RVEF). Methods: A single-center, retrospective cohort study was performed. Adult patients with a systemic RV who underwent a combination of both CMR and echocardiography at two different points in time were included. Off-line analysis of echocardiographic images was blinded to off-line CMR analysis and vice versa. In half of the echocardiograms, measurements were repeated by a second observer blinded to the results of the first. Correlations between echocardiographic and CMR measures were assessed with Pearson's correlation coefficient and interobserver agreement was quantified with intraclass correlation coefficients (ICC). Results: Fourteen patients were included, of which 4 had congenitally corrected transposition of the great arteries (ccTGA) and 10 patients had TGA late after an atrial switch operation. Eight patients (57%) were female. There was a mean of 8 years between the first and second imaging assessment. Only global systemic RV function, fractional area change (FAC), and global longitudinal strain (GLS) were consistently, i.e., at both time points, correlated with CMR-RVEF (global RV function: r = -0.77/r = -0.63; FAC: r = 0.79/r = 0.67; GLS: r = -0.73/r = -0.70, all p-values < 0.05). The ICC of GLS (0.82 at t = 1, p = 0.006, 0.77 at t = 2, p = 0.024) was higher than the ICC of FAC (0.35 at t = 1, p = 0.196, 0.70 at t = 2, p = 0.051) at both time points. Conclusion: GLS appears to be the most robust echocardiographic measurement of systemic RV function with good correlation with CMR-RVEF and reproducibility.

Abstract
BACKGROUND The study aimed to assess the relation between echocardiographic parameters of subpulmonary left ventricular (LV) size and function, and the severity of heart failure in patients with a systemic right ventricle (SRV). METHODS AND RESULTS A total of 157 patients (89 post Mustard/Senning operations, 68 with congenitally corrected transposition of great arteries [ccTGA]) were included. The size and function of the SRV and subpulmonary LV were assessed on the most recent echocardiographic exam. Clinical data were collected from the electronic records. The majority (133, 84.7%) were in NYHA functional class 1-2. Median BNP concentration was 79.5[38.3-173.3] ng/l, and 100 (63.7%) patients were receiving heart failure therapy. Both LV and SRV fractional area change (FAC) differed significantly between patients with NYHA class 1-2 vs 3-4 (48[41.5-52.8]% vs 34[28.6-38.6]%, p < 0.0001 and 29.5[23-35]% vs 22[20-27]%, p < 0.0001, respectively), but LV FAC had a higher discriminative power for functional class >2 than SRV FAC (AUC 0.90, p < 0.0001 vs 0.79; p < 0.0001, respectively). A LV FAC cut-off value <39.2% had the highest accuracy in identifying patients with NYHA class 3-4 (sensitivity 83% and specificity 88%). In multivariable logistic regression analysis, LV FAC and SRV FAC independently associated to NYHA class 3-4 (OR 0.80 [95%CI 0.72-0.88], p < 0.0001 and OR 0.85 [95%CI 0.76-0.96], p = 0.007, respectively). CONCLUSIONS Subpulmonary LV systolic dysfunction is associated with NYHA functional class 3-4 in patients with ccTGA or after Mustard or Senning operation. Careful evaluation of the subpulmonary LV should be a part of the routine assessment of patients with a SRV.

Abstract
Introduction In this study, we assessed the adequacy of the two echocardiographic parameters representing the longitudinal systolic function of the ventricles, MAPSE & TAPSE, in perioperative monitoring. Aims 1. The assessment of MAPSE and TAPSE during the early (4 weeks) postoperative period after surgical correction of congenital heart defects in infants, performed with CPB. 2. The verification of the hypothesis, that the significant decline of TAPSE observed in this period is not related to the global RV systolic dysfunction. For this reason, systolic function of the RV was additionally assessed with another echocardiographic parameter: RVFAC. Material and methods Prospective study with 51 infants operated due to ASDII, VSD, AVSD and TOF. Four measurements of MAPSE,TAPSE and RVFAC were performed in the apical four-chamber projection. TAPSE and MAPSE were expressed as metric values and z-score; RV FAC values were expressed in percentages. Results TAPSE uniformly declined in the first postoperative day down to 34.5% of the initial value (p <0.00001), then gradually increased: up to 42.9% and 52% respectively, remaining significantly lower than preoperatively (p <0.001). RV FAC: increased by 21% (p <0.01), then remained stable in consecutive examinations. MAPSE declined by 21% during the first postoperative day, but with promptly normalized completely. Conclusions The movement of both AV valve annuli is subjected to different, not fully understood influences. The relatively slight decline of MAPSE makes this parameter suitable for the assessment of the postoperative LV systolic function. Deep, long-lasting decline of TAPSE, uniform in the whole group, does not permit to use this parameter and suggests the choice of another one, e.g. RVFAC.

Abstract
BACKGROUND Scarce data on crowdfunding report a maximal funding of €10.000,-, and state that research is needed to attract attention of larger granting organizations. The aims of this project were 1) to fund an eHealth study in grown-up congenital heart disease (GUCH) patients 2) to contemplate on critical success factors. METHODS After peer review of the Dutch Heart Foundation a project was published at a donation platform, which was open for donations during a predetermined period of two months. Copywriters were hired to create an easy-to-understand message to donors. A video teaser was created with a motivated patient, and rewards were available. The crowdfunding targeted €25.000 and the Dutch Heart Foundation doubled the donations to €50.000, and return of donations were guaranteed in case this was not met. RESULTS Initially, donations came from the investigators' private inner circle. In total, 44 potential donors were contacted, but refused to donate originally. Multiple (social) media campaigns were published to promote the project, and an offline mailing was sent to contributors to the Dutch Heart Foundation. During the project support emerged, resulting in extra donations and public awareness. In the lasts three weeks, after sufficient private donations, five major donors decided to support the project. The project became a big success: the predetermined target was exceeded and a total of €74.450,- was raised. CONCLUSION Innovative crowdfunding gave the opportunity to start eHealth research in GUCH patients. Critical success factors include support of a professional organization, support of stakeholders, and easy-to-understand messages.

Abstract
BACKGROUND Adults with transposition of the great arteries (TGA) after atrial switch repair have an increased risk for arrhythmia and sudden cardiac death. We analyzed whether a remote monitoring (RM) system as part of an implantable cardiac device contributes to timely recognition and improved treatment of critical arrhythmias in these patients. METHODS AND RESULTS All consecutive TGA patients (n=11) requiring a pacemaker or cardiac resynchronization therapy with or without implantable cardioverter defibrillator between 2008 and 2011 were included. RM-detected arrhythmia, abnormality of device integrity and reaction time from event transmission until acknowledgement via email and clinical decision making were analyzed and compared to a control group (n=21). In 10 patients (91%) 17 arrhythmias were detected, 8 patients (80%) indicated no symptoms. In the RM group time interval from transmission to acknowledgement was 2.4 days (range, 0-4.5 days). Clinical decision-making was advanced by a mean of 77.5 days (range, 10-197 days) compared with conventional follow-up and identified adaption of anti-arrhythmic medication in 8, electrical cardioversion in 2, overdrive pacing in 1 and radiofrequency ablation in 2 patients. A coronary sinus lead fracture was identified in 1 patient followed by successful replacement. CONCLUSIONS RM enables early detection of tachyarrhythmia followed by optimization of medical treatment and potentially life-saving anti-tachycardic intervention in adults after atrial repair of TGA.

Abstract
Background—
The role of angiotensin II receptor blockers in patients with a systemic right ventricle has not been elucidated.
Methods and Results—
We conducted a multicenter, double-blind, parallel, randomized controlled trial of angiotensin II receptor blocker valsartan 160 mg twice daily compared with placebo in patients with a systemic right ventricle caused by congenitally or surgically corrected transposition of the great arteries. The primary end point was change in right ventricular ejection fraction during 3-year follow-up, determined by cardiovascular magnetic resonance imaging or, in patients with contraindication for magnetic resonance imaging, multirow detector computed tomography. Secondary end points were change in right ventricular volumes and mass,
peak, and quality of life. Primary analyses were performed on an intention-to-treat basis. A total of 88 patients (valsartan, n=44; placebo, n=44) were enrolled in the trial. No serious adverse effects occurred in either group. There was no significant effect of 3-year valsartan therapy on systemic right ventricular ejection fraction (treatment effect, 1.3%; 95% confidence interval, −1.3% to 3.9%;
P
=0.34), maximum exercise capacity, or quality of life. There was a larger increase in right ventricular end-diastolic volume (15 mL; 95% confidence interval, 3–28 mL;
P
<0.01) and mass (8 g; 95% confidence interval, 2–14 g;
P
=0.01) in the placebo group than in the valsartan group.
Conclusions—
There was no significant treatment effect of valsartan on right ventricular ejection fraction, exercise capacity, or quality of life. Valsartan was associated with a similar frequency of significant clinical events as placebo. Small but significant differences between valsartan and placebo were present for change in right ventricular volumes and mass.

Abstract
INTRODUCTION AND OBJECTIVE The present study aims to quantitatively evaluate the right ventricle (RV) function by means of transthoracic echocardiography in normal children and childhood congenital heart disease patients with pulmonary hypertension. PATIENTS AND METHODS This study was conducted in a cohort including 40 healthy children and 30 pediatric patients with pulmonary hypertension who were diagnosed under close surveillance at the study center between October 2009 and November 2010. RESULTS Statistically significant differences were found between the patient and control groups for the right ventricle myocardial performance index (RVMPI), the left ventricle myocardial performance index (LVMPI), the tricuspid valve systolic flow velocity (Ts), the ratio of systolic pulmonary artery pressure to the right ventricle outflow tract systolic flow velocity time integral (sPAP/RVOT VTI), and the ratio of systolic pulmonary artery pressure to right ventricle outflow tract systolic flow velocity time integral × heart rate (sPAP/[RVOT VTI×HR]). When the children were divided into three groups based on their pulmonary vascular resistance significant differences emerged that predicted an increasing severity of RV dysfunction. Significant differences were also observed for the RVMPI, the LVMPI, and the Ts as well as for echocardiographic pulmonary flow (Qp) and systemic flow (Qs). DISCUSSION The present study demonstrates that echocardiographic parameters can be used for the quantitative detection of RV dysfunction in childhood congenital heart disease patients with high pulmonary artery pressure (systolic, diastolic, and mean) or pulmonary vascular resistance.

Abstract
Outcomes in patients with ventricular dysfunction undergoing superior cavopulmonary connection (SCPC) are not well known. We reviewed records of patients undergoing SCPC at our center from December 2005 to October 2009 and studied those whose pre-SCPC echocardiograms demonstrated at least moderate systemic ventricular dysfunction. Of the 213 patients undergoing SCPC, 19 (9%) met inclusion criteria. Diagnoses were hypoplastic left heart syndrome (n = 18) and rightward unbalanced atrioventricular canal with pulmonary stenosis (n = 1). In those surviving >2 months after SCPC, ventricular function was assessed by echocardiography 4.9 (range 3.5 to 9.7) months after SCPC and was improved in ten of 17 (59%), unchanged in six of 17 (35%), and worsened in one of 17 (16%) patients. After SCPC, three patients died, and one underwent heart transplant 21.9 months after SCPC. Transplant-free survival was attained by 15 of 19 (79%) patients during follow-up of 33.0 months (range 10.8 to 51.4). Fontan completion was performed on six survivors on reaching an appropriate age. Ventricular dysfunction before SCPC is not uncommon and occurs primarily in patients with a morphologic right ventricle. Ventricular performance improves in the majority of patients after SCPC, and midterm outcomes are comparable with previous reports, suggesting that these patients remain candidates for staged palliation.
