Abstract
INTRODUCTION AND OBJECTIVES Our aim was to assess the impact of prosthetic pulmonary valve replacement (PVR) in patients with repaired tetralogy of Fallot (rTOF) on changes in biventricular volumes and function and on adverse cardiac events. METHODS Adults with rTOF were identified from the SACHER-registry. Data from serial cardiac magnetic resonance imaging, echocardiography, exercise capacity and n-terminal pro b-type natriuretic peptide (NT-proBNP) were collected. The primary endpoint was right ventricular ejection fraction (RVEF) as measured by cardiac magnetic resonance. Secondary endpoints were biventricular volumes, left ventricular ejection fraction, exercise capacity and NT-proBNP levels, and time to adverse cardiac outcomes (atrial and ventricular arrhythmia, endocarditis). Associations between previous PVR and longitudinal changes in functional outcomes and time to adverse cardiac outcomes were analyzed using linear mixed-effects models and Cox proportional hazards models, respectively. RESULTS A total of 308 patients (153 with and 155 without PVR) with 887 study visits were analyzed. Previous PVR was not significantly associated with changes in RVEF (CE, -1.33; 95%CI, -5.87 to 3.21; P=.566). Previous PVR was associated with lower right ventricular end-diastolic volume but had no significant effect on left ventricular ejection fraction, exercise capacity, or NT-proBNP-levels. Previous PVR was associated with an increased hazard of atrial arrhythmias (HR, 2.09; 95%CI, 1.17-3.72; P=.012) and infective endocarditis (HR, 12.72; 95%CI, 4.69-34.49; P<.0001) but not with an increased hazard of sustained ventricular arrhythmias (HR, 0.64; 95%CI, 0.18-2.27; P=.490). CONCLUSIONS Previous PVR was not significantly associated with changes in RVEF but was associated with an increased risk of atrial arrhythmias and infective endocarditis.

Abstract
OBJECTIVE Residual sequelae after surgical repair of tetralogy of Fallot (rTOF) affect clinical outcome. We investigated the prognostic impact of right ventricular (RV) dyssynchrony in adults with rTOF years after the surgical repair. METHODS Patients from the Swiss Adult Congenital HEart disease Registry were included. NT-proBNP levels, echocardiography, exercise testing and MRI data were collected. An offline strain analysis to quantify RV-ventricular and interventricular dyssynchrony was performed. The standard deviation of the time-to-peak shortening (TTP) of six RV segments defined the RV Dyssynchrony Index (RVDI). Maximal difference of TTP between RV and left ventricular segments defined the interventricular shortening delay (IVSD). Predictors of a composite adverse event (arrhythmias, hospitalisation for heart failure and death) were identified by multivariate Cox regression analysis. Their median values were used to create a risk score. RESULTS Out of 285 included patients (mean age 34±14 years), 33 patients (12%) experienced an adverse event during a mean follow-up of 48±21 months. No correlation was found between RVDI, IVSD and clinical events. NT-proBNP, right atrial area and peak heart rate were independent predictors of outcomes. After 4 years-follow-up, no adverse events occurred in patients at low risk (score=0 points), while an adverse event occurred in 62% of patients at high risk (score=3 points, p<0.001). CONCLUSION In our cohort of adults with rTOF, surrogates of RV dyssynchrony did not correlate with outcomes. A multimodality approach was effective in predicting the risk for adverse events.

Abstract
AIMS In adults with congenital heart disease and systemic right ventricles, progressive right ventricular systolic dysfunction is common and is associated with adverse outcomes. Our aim was to assess the impact of the phosphodiesterase-5-inhibitor tadalafil on right ventricular systolic function. METHODS AND RESULTS This was a double-blind, randomized, placebo-controlled, multicentre superiority trial (NCT03049540) involving 100 adults with systemic right ventricles (33 women, mean age: 40.7 ± 10.7 years), comparing tadalafil 20 mg once daily versus placebo (1:1 ratio). The primary endpoint was the change in right ventricular end-systolic volume after 3 years of therapy. Secondary endpoints were changes in right ventricular ejection fraction, exercise capacity and N-terminal pro-B-type natriuretic peptide concentration. Primary endpoint assessment by intention to treat analysis at 3 years of follow-up was possible in 83 patients (42 patients in the tadalafil group and 41 patients in the placebo group). No significant changes over time in right ventricular end-systolic volumes were observed in the tadalafil and the placebo group, and no significant differences between treatment groups (3.4 ml, 95% confidence interval -4.3 to 11.0, p = 0.39). No significant changes over time were observed for the pre-specified secondary endpoints for the entire study population, without differences between the tadalafil and the placebo group. CONCLUSIONS In this trial in adults with systemic right ventricles, right ventricular systolic function, exercise capacity and neuro-hormonal activation remained stable over a 3-year follow-up period. No significant treatment effect of tadalafil was observed. Further research is needed to find effective treatment for improvement of ventricular function in adults with systemic right ventricles.

Abstract
Abstract
Introduction
Atrial arrhythmias are a common and important cause of morbidity and mortality in adults with congenital heart disease (ACHD). In acquired heart disease, left atrial (LA) strain has been shown to predict supraventricular tachyarrhythmias (SVT). This study sought to investigate if LA strain is also a reliable predictor of SVT in the ACHD population.
Method
We retrospectively obtained baseline clinical and echocardiographic data, including LA function parameters and strain, in 206 ACHD patients. Only patients with sinus rhythm at baseline and 5-years follow-up were included (median age 29, IQR 22–41 years). 157 participants had a left heart defect (aortic stenosis or aortic coarctation, with or without correction) and 49 a right heart defect (Fallot physiology). Diagnosis of sustained SVT was determined from clinical reports during the follow-up period (standard 12-lead ECG, ECG Holter).
Results
During a median follow-up of 6.2 years, a new or recurrent sustained SVT occurred in 16 patients (7.8%). Patients baseline characteristics are depicted in Table 1. Patients who developed SVT were older, had larger LA dimensions and left ventricular mass, more likely diastolic dysfunction on echo, and a lower peak LA longitudinal strain (PALS). PALS was a good predictor of SVT risk in patients with left and right heart defects with an area under the receiver-operating-curve of 0.857. By Cox regression analysis, patient in the lowest quartile for PALS had a 16.7-fold higher hazard ratio of SVT (95% confidence interval, 4.7 to 59.0, p<0.001) in comparison with the top three quartiles. Overall freedom from arrhythmia after 1, 3 and 5 years of follow-up was 98.1%, 96.1% and 94.2%, respectively. The freedom from SVT as a function of PALS quartiles is shown in Figure 1.
Conclusion
PALS provides predictive information about the occurrence of SVT in the ACHD population, regardless of the type of the lesion. Including the measurement of LA strain in the follow-up of these patients may permit to better identify patients at risk of future atrial arrhythmias.

Abstract
Our aim was to assess changes of right ventricular end-diastolic volumes (RVEDVi) and right ventricular ejection fraction (RVEF) in asymptomatic adults with repaired tetralogy of Fallot, with native right ventricular outflow tract and severe pulmonary regurgitation by serial cardiac magnetic resonance imaging (CMR). The study included 23 asymptomatic adults who underwent ≥3 CMR studies (total of 88 CMR studies). We compared changes in RVEDVi and RVEF between first and last study (median follow-up: 8.8 years, interquartile range: 6.3 to 13.1 years) and between all study pairs. Variability of measurements between study pairs (65 consecutive and 139 nonconsecutive CMR study pairs) were assessed using Bland-Altman analysis and intraclass correlation coefficients. On average, there were no significant changes of RVEDVi or RVEF over the study period (change in RVEDVi: +0.4 ± 17.8 ml/m2, change in RVEF: -1.0 ± 5.5%). Assessment of variability of measurements between study pairs demonstrated no systematic change in RVEDVi and RVEF between study pairs with limits of agreement within the range of previously published studies (RVEDVi -29.1 to +27.2 ml/m2; RVEF -11.5% to 10.2%). High intraclass correlation coefficients for RVEDVi (0.943, 95% CI 0.906 to 0.965, p <0.001) and RVEF (0.815, 95% CI 0.697 to 0.887, p <0.0001) indicate high reliability of reported measurements. In conclusion, in asymptomatic adults with repaired tetralogy of Fallot with native right ventricular outflow tracts and severe pulmonary regurgitation, CMR measurements of RV volumes and RVEF remain stable during follow-up with variability between CMR studies in individual patients, as expected for interobserver and interstudy variability. Measurements derived from a single CMR study or changes occurring between 2 CMR studies should be used with caution for clinical decision-making.

Abstract
ZusammenfassungIm ersten Teil des vorliegenden Beitrags wurde im Detail auf die Genetik, Diagnose, Differenzialdiagnose, die diagnostische Bildgebung, Follow-up, die kardiovaskulären Probleme sowie die Manifestation an Aorta und den großen Gefäßen bei Patienten mit dem Marfan-Syndrom (MFS) eingegangen. In diesem zweiten Teil werden die medikamentöse Therapie des MFS, seine Bedeutung im Zusammenhang mit einer Schwangerschaft, die Beteiligung von Augen und Wirbelsäule bei MFS-Patienten sowie die organisatorischen Aspekte einer Marfan-Sprechstunde erläutert. Das MFS ist mit einer Prävalenz von etwa 1–2:10.000 die häufigste hereditäre Bindegewebserkrankung mit vaskulärer Komponente. Ursache sind Mutationen im Gen, das für das extrazelluläre Matrixprotein Fibrillin‑1 kodiert. Die Erkrankung wird autosomal-dominant vererbt. Es handelt sich um eine Multisystemerkrankung mit Beteiligung der Aorta, der Mitralklappe, Augen- und Skelettveränderungen. Die Augen- und/oder die Wirbelsäulenbeteiligung sind nicht zu unterschätzen, da sowohl die Skoliose als auch die Linsendislokation etwa 60 % der Patienten mit MFS betreffen. Bis anhin konnte kein Wirkstoff einen klaren Vorteil hinsichtlich klinischer Ereignisse in MFS-Patienten zeigen. Es besteht jedoch der allgemeine Konsens, Patienten mit MFS einen β‑Rezeptoren- oder Angiotensinrezeptorblocker isoliert oder als Kombinationstherapie zu verabreichen. Bei bestehendem Kinderwunsch muss ein besonderes Augenmerk auf die Planung der Schwangerschaft gelegt werden. Im Fall eines Aortenwurzeldurchmessers > 4–4,5 cm empfiehlt sich, entweder einen prophylaktischen Aortenwurzelersatz zu erwägen oder von einer Schwangerschaft abzuraten. Eine strukturierte Langzeitbetreuung ist für Patienten mit MFS essenziell.

Abstract
Background: To compare the diagnostic yield of echocardiography and cardiovascular MRI (CMR) to detect structural sources of embolism, in patients with ischemic stroke with a secondary analysis of non-stroke populations. Methods and Results: We searched MEDLINE/Embase (from 01.01.2000 to 24.04.2021) for studies including CMR to assess prespecified sources of embolism. Comparison included transthoracic and/or transesophageal echocardiography. Two authors independently screened studies, extracted data and assessed bias using the QUADAS-2 tool. Estimates of diagnostic yield were reported and pooled. Twenty-seven studies with 2,525 patients were included in a study-level analysis. Most studies had moderate to high risk of bias. Persistent foramen ovale, complex aortic plaques, left ventricular and left atrial thrombus were the most common pathologies. There was no difference in the yield of left ventricular thrombus detection between both modalities for stroke populations (4 studies), but an increased yield of CMR in non-stroke populations (28.1 vs. 16.0%, P < 0.001, 10 studies). The diagnostic yield in stroke patients for detection of persistent foramen ovale was lower in CMR compared to transoesophageal echocardiography (29.3 vs. 53.7%, P < 0.001, 5 studies). For both echocardiography and CMR the clinical impact of the management consequences derived from many of the diagnostic findings remained undetermined in the identified studies. Conclusions: Echocardiography and CMR seem to have similar diagnostic yield for most cardioaortic sources of embolism except persistent foramen ovale and left ventricular thrombus. Randomized controlled diagnostic trials are necessary to understand the impact on the management and potential clinical benefits of the assessment of structural cardioaortic stroke sources.

Abstract
We present a multi-scale CFD-based study conducted in a cohort of 11 patients with coarctation of the aorta (CoA). The study explores the potential for implementation of a workflow using non-invasive routinely collected medical imaging data and clinical measurements to provide a more detailed insight into local aortic haemodynamics in order to support clinical decision making. Our approach is multi-scale, using a reduced-order model (1D/0D) and an optimization process for the personalization of patient-specific boundary conditions and aortic vessel wall parameters from non-invasive measurements, to inform a more complex model (3D/0D) representing 3D aortic patient-specific anatomy. The reliability of the modelling approach is investigated by comparing 3D/0D model pressure drop estimation with measured peak gradients recorded during diagnostic cardiac catheterization and 2D PC-MRI flow rate measurements in the descending aorta. The current study demonstrated that the proposed approach requires low levels of user interaction, making it suitable for the clinical setting. The agreement between computed blood pressure drop and catheter measurements is 10 ± 8 mmHg at the coarctation site. The comparison between CFD derived and catheter measured pressure gradients indicated that the model has to be improved, suggesting the use of time varying pressure waveforms to further optimize the tuning process and modelling assumptions.

Abstract
Cardiac implantable electronic device–related infection is clinically challenging. Curative treatment commonly includes system removal. A case caused by Granulicatella adiacens occurred in a 32-year-old woman. Clinical course, literature review, and biofilm investigations enabled successful antibiotic management without system removal.

Abstract
Trisomy 21 (T21) is associated in 40-45% of cases with heart defects, most commonly shunt lesions. These defects, if not repaired, can lead to irreversible shunt-induced pulmonary hypertension (i.e. Eisenmenger syndrome [ES]). In ES patients, intracardiac repair is no longer possible, but selective pulmonary vasodilators may increase exercise capacity and improve prognosis. This study aimed to estimate the prevalence of cardiac defects and ES in adult T21 patients and to assess the impact of T21 on treatment modalities and outcome in ES patients. A questionnaire was sent to 6906 Swiss physicians inviting them to indicate the number of adults with T21 under their care (survey report). We also analyzed all adults with ES (with and without T21) included in the Swiss Adult Congenital HEart disease Registry (SACHER) and studied the impact of T21 on the use of selective pulmonary vasodilators and survival. In the survey, 348 physicians cared for 695 adult T21 patients. Overall, 24% of T21 survey patients were known to have a cardiac defect, one in four with a defect had developed ES and 13% of those with ES were on specific pulmonary vasodilators. In SACHER, ES was present in 2% of adults with congenital heart disease and selective pulmonary vasodilators were used in 68% of ES patients with T21. In SACHER, survival during follow-up was worse with higher nt-proBNP levels (hazard ratio [HR] = 1.15 per 1000 units, 95% confidence interval [CI] = 1.02-1.29) and lower left ventricular ejection fraction (HR = 1.07 per percent decrease, 95% CI = 1.01-1.13). Age at inclusion and T21 did not affect survival. The prevalence of cardiac defects in adults with T21 in Switzerland is half the prevalence in children. T21 is over-represented among adults with ES. Raised awareness of the therapeutic options for T21 patients with ES is warranted.

Abstract
A sofosbuvir/ledipasvir combination is part of a first-line treatment of hepatitis C. However, in patients concurrently treated with amiodarone, cardiac side effects have been described, resulting in an official warning in 2015 by the American Food and Drug Administration and the European Medicines Agency when combining those substances. This deprived numerous hepatitis C patients with concurrent cardiovascular problems of receiving this highly effective treatment. Here we present a treatment alternative with an elbasvir/grazoprevir regimen, based on our successful treatment of a patient under concurrent amiodarone therapy. Our observations indicate that patients treated with amiodarone can finally benefit from effective antiviral therapy.

Abstract
BACKGROUND In 2013, a prospective registry for adults with congenital heart disease (CHD) was established in Switzerland, providing detailed data on disease characteristics and outcomes: Swiss Adult Congenital HEart disease Registry (SACHER). Its aim is to improve the knowledge base of outcomes in adults with CHD. The registry design and baseline patient characteristics are reported. METHODS All patients with structural congenital heart defects or hereditary aortopathies, followed-up at dedicated adult CHD clinics, are asked to participate in SACHER. Data of participants are pseudonymised and collected in an electronic, web-based, database (secuTrial®). Collected data include detailed diagnosis, type of repair procedures, previous complications and adverse outcomes during follow-up. RESULTS From May 2014 to December 2016, 2836 patients (54% male, mean age 34 ± 14 years), with a wide variety of congenital heart lesions, have been enrolled into SACHER. Most prevalent were valve lesions (25%), followed by shunt lesions (22%), cyanotic and other complex congenital heart disease (16%), diseases affecting the right heart, i.e., tetralogy of Fallot or Ebstein anomaly (15%), and diseases of the left ventricular outflow tract (13%); 337 patients (12%) had concomitant congenital syndromes. The majority had undergone previous repair procedures (71%), 47% of those had one or more reinterventions. CONCLUSION SACHER collects multicentre data on adults with CHD. Its structure enables prospective data analysis to assess detailed, lesion-specific outcomes with the aim to finally improve long-term outcomes.

Abstract
Nowadays, more than 90% of all children born with congenital heart disease (CHD) reach adult life. Although initially considered to be cured, the majority of them continue to need specialised follow-up because they require re-do interventions or are at increased risk of cardiovascular complications and premature death. Arrhythmias are the most common cause of unscheduled hospital visits for grown-up CHD (GUCH) patients, accounting for one third of emergency admissions in these patients. Some GUCH patients are also at increased risk for sudden cardiac death. The principles of arrhythmia management and the prevention of sudden cardiac death in GUCH patients are similar to those used in adults with acquired heart disease, but are not evidence based. Decompensated heart failure is the other leading cause of death. Conventional medical heart-failure therapy for left ventricular dysfunction is not effective in GUCH patients at highest risk of heart failure, i.e., those with right or single ventricular failure. Careful haemodynamic assessment and structural interventions are the first step to consider in GUCH patients presenting with heart failure symptoms. Adults with moderate or complex CHD and regular follow-up in specialised GUCH centres have a survival benefit compared with patients without such follow-up. Cardiac surgery in GUCH patients should be performed by surgeons trained in treatment of CHD, i.e., surgeons also operating on paediatric patients. A structured transition programme with a defined transfer of care from the paediatric to the adult care environment is important to avoid lapses of care in today's adolescents with CHD. For GUCH patients with an intervention performed decades ago and no specific cardiac follow-up in later life, referral to a specialised GUCH centre is recommended and may save lives.

Abstract
OBJECTIVE Adults with congenital heart disease (CHD) are at increased risk of infective endocarditis (IE). Women with CHD have a lower IE risk, potentially due to gender-related differences in dental care. We aimed to assess self-reported dental hygiene measures in adults with CHD, and to identify factors associated with good oral hygiene. METHODS AND RESULTS Descriptive study includes 187 adults with CHD at increased risk of IE. The patients' IE knowledge was assessed using an adapted version of the Leuven Knowledge Questionnaire for CHD. Their mean age was 34.9±14.9 years, 73 of them (39%) were women, 91 (49%) were at high risk for IE, including 66 (35%) with a prosthetic valve, 14 (7%) with a history of IE and 11 (6%) with cyanotic CHD or residual shunts/valvular regurgitation in the proximity of prosthetic material. The self-defined IE knowledge score did not differ between men and women (21.6±10.0 vs 23.4±10.0; p=0.225). 126 patients (67%) reported to have a good oral hygiene. Female gender (OR 2.4, 95% CI 1.1 to 4.4), and a higher IE knowledge score (OR 1.2, 95% CI 1.1 to 1.5, per 5 points) were the variables independently associated with good oral hygiene. CONCLUSIONS In adults with CHD, patients with a higher IE knowledge score and women are more likely to practise dental care as recommended. Gender differences in oral hygiene practise may explain the observed lower female IE incidence rate. Efforts to improve patients' knowledge on IE are encouraged.

Abstract
The aim of our study was to evaluate 3-dimensional (3D) color Doppler proximal isovelocity surface area (PISA) as a tool for quantitative assessment of mitral regurgitation (MR) against in vitro and in vivo reference methods. A customized 3D PISA software was validated in vitro against a flowmeter MR phantom. Sixty consecutive patients, with ≥mild MR of any cause, were recruited and the regurgitant volume (RVol) was measured by 2D PISA, 3D peak PISA, and 3D integrated PISA, using transthoracic (TTE) and transesophageal echocardiography (TEE). Cardiac magnetic resonance imaging (CMR) was used as reference method. Flowmeter RVol was associated with 3D integrated PISA as follows: y = 0.64x + 4.7, r(2) = 0.97, p <0.0001 for TEE and y = 0.88x + 4.07, r(2) = 0.96, p <0.0001 for TTE. The bias and limit of agreement in the Bland-Altman analysis were 6.8 ml [-3.5 to 17.1] for TEE and -0.059 ml [-6.2 to 6.1] for TTE. In vivo, TEE-derived 3D integrated PISA was the most accurate method for MR quantification compared to CMR: r(2) = 0.76, y = 0.95x - 3.95, p <0.0001; 5.1 ml (-14.7 to 26.5). It was superior to TEE 3D peak PISA (r(2) = 0.67, y = 1.00x + 6.20, p <0.0001; -6.3 ml [-33.4 to 21.0]), TEE 2D PISA (r(2) = 0.54, y = 0.76x + 0.18, p <0.0001; 8.4 ml [-20.4 to 37.2]), and TTE-derived measurements. It was also most accurate by receiver operating characteristic analysis (area under the curve 0.99) for the detection of severe MR, RVol cutoff = 48 ml, sensibility 100%, and specificity 96%. RVol and the cutoff to define severe MR were underestimated using the most accurate method. In conclusion, quantitative 3D color Doppler echocardiography of the PISA permits a more accurate MR assessment than conventional techniques and, consequently, should enable an optimized management of patients suffering from MR.

Abstract
Background—
Restrictive lung defects are associated with higher mortality in patients with acquired chronic heart failure. We investigated the prevalence of abnormal lung function, its relation to severity of underlying cardiac defect, its surgical history, and its impact on outcome across the spectrum of adult congenital heart disease.
Methods and Results—
A total of 1188 patients with adult congenital heart disease (age, 33.1±13.1 years) undergoing lung function testing between 2000 and 2009 were included. Patients were classified according to the severity of lung dysfunction based on predicted values of forced vital capacity. Lung function was normal in 53% of patients with adult congenital heart disease, mildly impaired in 17%, and moderately to severely impaired in the remainder (30%). Moderate to severe impairment of lung function related to complexity of underlying cardiac defect, enlarged cardiothoracic ratio, previous thoracotomy/ies, body mass index, scoliosis, and diaphragm palsy. Over a median follow-up period of 6.7 years, 106 patients died. Moderate to severe impairment of lung function was an independent predictor of survival in this cohort. Patients with reduced force vital capacity of at least moderate severity had a 1.6-fold increased risk of death compared with patients with normal lung function (
P
=0.04).
Conclusions—
A reduced forced vital capacity is prevalent in patients with adult congenital heart disease; its severity relates to the complexity of the underlying heart defect, surgical history, and scoliosis. Moderate to severe impairment of lung function is an independent predictor of mortality in contemporary patients with adult congenital heart disease.

Abstract
Structural abnormalities of the medial aorta have been described for conotruncal defects (e.g., tetralogy of Fallot [TOF] and complete transposition of the great arteries (dextrotransposition [d]-TGA). In TOF, progressive aortic dilation is a frequent finding. In patients with d-TGA with an atrial switch, this problem is less often described. The aim of the present study was to compare the extent of dilative aortopathy and aortic distensibility in adults with an atrial switch procedure (n = 39) to that in adults with repaired TOF (n = 39) and controls (n = 39), using cardiac magnetic resonance imaging. The groups were matched for age and gender. Diameters of the aorta indexed to the body surface area were significantly increased in the patients with d-TGA and TOF compared to that of the controls at the aortic sinus up to the level of the right pulmonary artery. On multivariate testing, the diagnosis of a conotruncal defect (β = 0.260; p = 0.003) and aortic regurgitant fraction (β = 0.405; p <0.001) were independent predictors of an increased aortic sinus diameter. Ascending aorta distensibility was significantly reduced in those with d-TGA and TOF compared to controls: 3.6 (interquartile range 1.5 to 4.4) versus 2.8 (interquartile range 2.0 to 3.7) versus 5.5 (interquartile range 4.8 to 6.9) ×10(-3) mm Hg(-1) (p <0.001). The independent predictors of ascending aorta distensibility were the diagnosis of a conotruncal defect (p <0.001) and age (p = 0.028). In conclusion, intrinsic aortopathy, manifested as increased ascending aortic diameters and reduced ascending aortic distensibility, is not only evident in adults with TOF, but also in adults with d-TGA and an atrial switch procedure. Long-term follow-up is needed to monitor the aortic size in both patient groups.

Abstract
AIMS Right ventricular (RV) systolic function is prognostically important, but its assessment by echocardiography remains challenging, in part because of the multitude of available measurement methods. The purpose of this prospective study was to rank these methods against the reference of RV ejection fraction (EF) as obtained in a broad clinical population by magnetic resonance imaging (MRI). METHODS AND RESULTS Two hundred and twenty-three individuals were included in the study. The following seven Doppler echocardiographic parameters were tested using receiver operating characteristic (ROC) analysis for their accuracy to distinguish between normal and moderately impaired RVEF by MRI (RVEF cut-off 50%), respectively, between moderately and severely reduced RVEF (cut-off 30%): RV fractional area and fractional long-axis change (FLC), RV myocardial performance index (MPI), tricuspid annular peak systolic excursion, Doppler tissue imaging-derived isovolumic acceleration and peak systolic velocity (S') at the lateral tricuspid annulus, and strain at the lateral free wall as obtained by speckle-tracking echocardiography. Survival analysis was performed. All seven Doppler echocardiographic parameters correlated significantly with RVEF by MRI (range between 5 and 85%). RVEF <50% was best detected by S' < 11 cm/s: area under the ROC curve 0.779 (95% confidence interval 0.716-0.843), sensitivity 0.740, and specificity 0.753. RVEF ≤30% was best detected by MPI > 0.50: area under the ROC curve 0.948 (95% confidence interval 0.906-0.991), sensitivity 0.947, and specificity 0.852. The Kaplan-Meier analysis revealed reduced cumulative survival among patients with RVEF ≤30% (P = 0.0003). CONCLUSION A systolic long-axis peak velocity of <11 cm/s at the lateral tricuspid annulus most accurately detects moderately impaired RVEF as obtained by MRI; severely reduced RVEF ≤30% is best detected by RV MPI at a value of >0.50.

Abstract
Aberrant origin of a pulmonary artery from the ascending aorta is an uncommon congenital vascular malformation with poor survival without surgery. In this case report, we describe the unusual late diagnosis of this congenital malformation in an otherwise asymptomatic young man presenting with mild hemoptysis. We review the natural and modified history of this defect and the relevant aspects of follow-up in adult life.

Abstract
In patients with drug-resistant hypertension, chronic electric stimulation of the carotid baroreflex is an investigational therapy for blood pressure reduction. We hypothesized that changes in cardiac autonomic regulation can be demonstrated in response to chronic baroreceptor stimulation, and we analyzed the correlation with blood pressure changes. Twenty-one patients with drug-resistant hypertension were prospectively included in a substudy of the Device Based Therapy in Hypertension Trial. Heart rate variability and heart rate turbulence were analyzed using 24-hour ECG. Recordings were obtained 1 month after device implantation with the stimulator off and after 3 months of chronic electric stimulation (stimulator on). Chronic baroreceptor stimulation decreased office blood pressure from 185+/-31/109+/-24 mm Hg to 154+/-23/95+/-16 mm Hg (P<0.0001/P=0.002). Mean heart rate decreased from 81+/-11 to 76+/-10 beats per minute(-1) (P=0.001). Heart rate variability frequency-domain parameters assessed using fast Fourier transformation (FFT; ratio of low frequency:high frequency: 2.78 versus 2.24 for off versus on; P<0.001) were significantly changed during stimulation of the carotid baroreceptor, and heart rate turbulence onset was significantly decreased (turbulence onset: -0.002 versus -0.015 for off versus on; P=0.004). In conclusion, chronic baroreceptor stimulation causes sustained changes in heart rate variability and heart rate turbulence that are consistent with inhibition of sympathetic activity and increase of parasympathetic activity in patients with drug-resistant systemic hypertension; these changes correlate with blood pressure reduction. Whether the autonomic modulation has favorable cardiovascular effects beyond blood pressure control should be investigated in further studies.

Abstract
CONTEXT A shortening of the atrial refractory period has been considered as the main mechanism for the increased risk of atrial fibrillation in hyperthyroidism. However, other important factors may be involved. OBJECTIVE Our objective was to determine the activity of abnormal supraventricular electrical depolarizations in response to elevated thyroid hormones in patients without structural heart disease. PATIENTS AND DESIGN Twenty-eight patients (25 females, three males, mean age 43+/-11 yr) with newly diagnosed and untreated hyperthyroidism were enrolled in a prospective trial after exclusion of heart disease. Patients were followed up for 16 +/- 6 months and studied at baseline and 6 months after normalization of serum TSH levels. MAIN OUTCOME MEASURES The incidence of abnormal premature supraventricular depolarizations (SVPD) and the number of episodes of supraventricular tachycardia was defined as primary outcome measurements before the start of the study. In addition, heart rate oscillations (turbulence) after premature depolarizations and heart rate variability were compared at baseline and follow-up. RESULTS SVPDs decreased from 59 +/- 29 to 21 +/- 8 per 24 h (P = 0.003), very early SVPDs (so called P on T) decreased from 36 +/- 24 to 3 +/- 1 per 24 h (P < 0.0001), respectively, and nonsustained supraventricular tachycardias decreased from 22 +/- 11 to 0.5 +/- 0.2 per 24 h (P = 0.01) after normalization of serum thyrotropin levels. The hyperthyroid phase was characterized by an increased heart rate (93 +/- 14 vs. 79 +/- 8 beats/min, P < 0.0001) and a decreased turbulence slope (3.6 vs. 9.2, P = 0.003), consistent with decreased vagal tone. This was confirmed by a significant decrease of heart rate variability. CONCLUSION Hyperthyroidism is associated with an increased supraventricular ectopic activity in patients with normal hearts. The activation of these arrhythmogenic foci by elevated thyroid hormones may be an important causal link between hyperthyroidism and atrial fibrillation.

Abstract
BACKGROUND The prognostic relevance of the collateral circulation is still controversial. The goal of this study was to assess the impact on survival of quantitatively obtained, recruitable coronary collateral flow in patients with stable coronary artery disease during 10 years of follow-up. METHODS AND RESULTS Eight-hundred forty-five individuals (age, 62+/-11 years), 106 patients without coronary artery disease and 739 patients with chronic stable coronary artery disease, underwent a total of 1053 quantitative, coronary pressure-derived collateral measurements between March 1996 and April 2006. All patients were prospectively included in a collateral flow index (CFI) database containing information on recruitable collateral flow parameters obtained during a 1-minute coronary balloon occlusion. CFI was calculated as follows: CFI = (P(occl) - CVP)/(P(ao) - CVP) where P(occl) is mean coronary occlusive pressure, P(ao) is mean aortic pressure, and CVP is central venous pressure. Patients were divided into groups with poorly developed (CFI < 0.25) or well-grown collateral vessels (CFI > or = 0.25). Follow-up information on the occurrence of all-cause mortality and major adverse cardiac events after study inclusion was collected. Cumulative 10-year survival rates in relation to all-cause deaths and cardiac deaths were 71% and 88%, respectively, in patients with low CFI and 89% and 97% in the group with high CFI (P=0.0395, P=0.0109). Through the use of Cox proportional hazards analysis, the following variables independently predicted elevated cardiac mortality: age, low CFI (as a continuous variable), and current smoking. CONCLUSIONS A well-functioning coronary collateral circulation saves lives in patients with chronic stable coronary artery disease. Depending on the exact amount of collateral flow recruitable during a brief coronary occlusion, long-term cardiac mortality is reduced to one fourth compared with the situation without collateral supply.

Abstract
Background and Purpose—
For patients having suffered ischemic stroke, the current diagnostic strategies often fail to detect atrial fibrillation as a potential cause of embolic events. The aim of the study was to identify paroxysmal atrial fibrillation in stroke patients. We hypothesized that patients with frequent atrial premature beats (APBs) recorded in 24-hour ECG will show more often atrial fibrillation when followed by repeated long-term ECG recordings than patients without or infrequent APBs.
Methods—
127 patients with acute ischemic stroke and without known AF were enrolled in a prospective study to detect paroxysmal AF. Patients were stratified according to the number of APBs recorded in a 24-hour ECG (≥70 APBs versus <70 APBs). Subsequently, they all underwent serial 7-day event-recorder monitoring at 0, 3, and 6 months.
Results—
Serial extended ECG monitoring identified AF in 26% of patients with frequent APBs but only in 6.5% when APBs were infrequent (
P
=0.0021). A multivariate analysis showed that the presence of frequent APBs in the initial 24-hour ECG was the only independent predictor of paroxysmal AF during follow-up (odds ratio 6.6, 95% confidence intervals 1.6 to 28.2,
P
=0.01).
Conclusions—
In patients with acute ischemic stroke, frequent APBs (≥70/24 hours) are a marker for individuals who are at greater risk to develop or have paroxysmal AF. For such patients, we propose a diagnostic workup with repeated prolonged ECG monitoring to diagnose paroxysmal AF.

Abstract
OBJECTIVES We tested the hypothesis that there was an association between tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) release and measured coronary collateral flow in patients undergoing primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI). BACKGROUND Tumour necrosis factor-alpha and IL-6 increase during acute myocardial infarction (AMI). However, their relation to coronary collateral flow is unknown. METHODS Twelve patients with AMI due to complete thrombotic coronary occlusion underwent primary PCI within 12 h of symptom onset. Doppler-derived collateral flow index (CFI) was measured during first balloon inflation. TNF-alpha, IL-6, creatine kinase (CK), CK-MB fraction were measured from venous plasma samples serially for 24 h. Area at risk was determined off-line by coronary arteriography. Ejection fraction (EF) was measured using biplane left ventricular angiography. RESULTS Maximal CK release varied between 569 and 6276 U/l and area at risk varied between 7 and 47% of myocardium. Tumour necrosis factor-alpha (peak 4.4+/-0.5 pg/ml) and IL-6 (peak 35.5+/-3.0 pg/ml) increased in all patients. Peak TNF-alpha and IL-6 release was independent of CK, CKMB. No minimal threshold of myocardial necrosis for cytokine expression could be detected. Similarly, TNF-alpha and IL-6 release was also independent of time to reperfusion, area at risk or EF. Using univariate regression analysis, peak TNF-alpha inversely correlated with CFI (r = 0.67, P = 0.017) whereas IL-6 positively correlated with CFI (r = 0.76, P = 0.004). CONCLUSIONS Acute myocardial infarction is associated with a significant rise in TNF-alpha and IL-6 levels independent of infarct size or myonecrosis. Tumour necrosis factor-alpha and IL-6 correlate dichotomously with CFI indicating differing roles in reperfused AMI.

Abstract
AIMS To test the hypothesis that Qr in V(1)is a predictor of pulmonary embolism, right ventricular strain, and adverse clinical outcome. METHODS AND RESULTS ECG's from 151 patients with suspected pulmonary embolism were blindly interpreted by two observers. Echocardiography, troponin I, and pro-brain natriuretic peptide levels were obtained in 75 patients with pulmonary embolism. Qr in V(1)(14 vs 0 in controls; p<0.0001) and ST elevation in V(1)> or =1 mV (15 vs 1 in controls; p=0.0002) were more frequently present in patients with pulmonary embolism. Sensitivity and specificity of Qr in V(1)and T wave inversion in V(2)for predicting right ventricular dysfunction were 31/97% and 45/94%, respectively. Three of five patients who died in-hospital and 11 of 20 patients with a complicated course, presented with Qr in V(1). After adjustment for right ventricular strain including ECG, echocardiography, pro-brain natriuretic peptide and troponin I levels, Qr in V(1)(OR 8.7, 95%CI 1.4-56.7; p=0.02) remained an independent predictor of adverse outcome. CONCLUSIONS Among the ECG signs seen in patients with acute pulmonary embolism, Qr in V(1)is closely related to the presence of right ventricular dysfunction, and is an independent predictor of adverse clinical outcome.

Abstract
BACKGROUND Thus far, it is unknown whether there is functional collateral flow through preexisting anastomoses in patients with angiographically normal coronary arteries. Such preformed coronary collateral vessels could form the basis for subsequently developing protective natural bypasses in the presence of coronary artery disease. METHODS AND RESULTS Among 100 patients, the collateral flow index (CFI) was measured in coronary arteries without stenotic lesions. The CFI was determined by simultaneous measurement of mean aortic pressure, central venous pressure, and coronary wedge pressure via a sensor-tipped guidewire at the end of a 1-minute balloon occlusion. Patients were divided in 2 groups according to complete angiographic absence (51 patients) or partial presence (49 patients) of stenotic lesions in coronary arteries other than that undergoing collateral measurement. CFI in all patients (61+/-10 years; men/women, 69/31) amounted to 0.18+/-0.08 (range, 0.04 to 0.36). It showed a normal Gaussian frequency distribution; 22 individuals had a CFI > or =0.25, a value that was empirically found to represent well-developed collaterals protective against myocardial ischemia during coronary occlusion. Accordingly, 17 patients did not reveal signs of myocardial ischemia during coronary balloon occlusion, as assessed from an intracoronary ECG, and 26 patients did not experience angina pectoris during occlusion. CONCLUSIONS In humans with angiographically normal coronary arteries, there are functional collateral vessels to the extent that one fifth to one quarter of them do not show signs of myocardial ischemia during brief vascular occlusions.

Abstract
In 50 patients undergoing percutaneous transluminal coronary angioplasty because of chronic angina pectoris, a collateral flow index (CFI) was determined at the start and the end of two 1-min coronary occlusions, randomly accompanied by a resting state or a 3-min dynamic handgrip exercise (DHE). CFI expressing collateral flow relative to normal antegrade flow was determined by simultaneous coronary occlusive pressure, mean aortic pressure and central venous pressure measurements. When comparing CFI without and with DHE at the start as well as at the end of balloon occlusions, a significant increase was observed with DHE (overall p < 0.0001); start: 0.18 +/- 0.12 vs. 0.22 +/- 0.13, respectively (p = 0.01); end of occlusion: 0.21 +/- 0.14 vs. 0.25 +/- 0.14, respectively (p = 0.007).

Abstract
OBJECTIVES We sought to determine the pathogenetic predictors of collateral channels in a large cohort of patients with coronary artery disease (CAD). BACKGROUND The frequency distribution of collateral flow in patients with CAD is unknown. Only small qualitative studies have investigated which factors influence the development of collateral channels. METHODS In 450 patients with one- to three-vessel CAD undergoing percutaneous transluminal coronary angioplasty (PTCA), collateral flow was measured. A collateral flow index (CFI; no unit) expressing collateral flow relative to normal anterograde flow was determined using coronary wedge pressure or Doppler measurements through sensor-tipped PTCA guide wires. Frequency distribution analysis of CFI and univariate and multivariate analyses of 32 factors, including gender, age, patient history, cardiovascular risk factors, medication and coronary angiographic data, were performed. RESULTS Two-thirds of the patients had a CFI < 0.25 and approximately 40% of patients had a CFI < 0.15, but only approximately 10% of the patients had a recruitable CFI > or =0.4. By univariate analysis, the following were predictors of CFI > or =0.25: high levels of high-density lipoprotein cholesterol, the absence of previous non-Q-wave myocardial infarction, angina pectoris during an exercise test, angiographic indicators of severe CAD and the left circumflex or right coronary artery as the collateral-receiving vessel. Percent diameter stenosis of the lesion undergoing PTCA was the only independent predictor of a high CFI. CONCLUSIONS This large clinical study of patients with CAD in whom collateral flow was quantitatively assessed reveals that two-thirds of the patients do not have enough collateral flow to prevent myocardial ischemia during coronary occlusion, and that coronary lesion severity is the only independent pathogenetic variable related to collateral flow.

Abstract
AIMS To assess the diagnostic accuracy of combined transmitral E wave velocity and reversed systolic pulmonary venous flow for the quantification of mitral regurgitation severity. METHODS AND RESULTS Measuring forward and total left ventricular stroke volume, mitral regurgitation severity was assessed quantitatively by calculating the regurgitant fraction in 106 consecutive patients with pure mitral regurgitation. According to the regurgitant fraction, the optimal E wave velocity for accurate distinction of mild to moderate and more than moderate mitral regurgitation was chosen by calculating the receiver-operating characteristic plot. Severe mitral regurgitation was defined by reversed systolic pulmonary venous flow. Combining transmitral E wave velocity and reversed systolic pulmonary venous flow had an overall accuracy of 78% (95% CI 70--86%) for classification of mitral regurgitation severity. E wave velocity >1.0ms(-1) predicted more than moderate mitral regurgitation with 78% sensitivity (95% CI 69-86%) and 90% specificity (95% CI 82--95%), resulting in a positive likelihood ratio of 8.1 (95% CI 5--15) and negative likelihood ratio of 0.25 (95% CI 0.18--0.35). For reversed systolic pulmonary venous flow in the presence of increased E wave velocity, the sensitivity and specificity to detect severe mitral regurgitation was 78% (95% CI 69--86%) and 97% (95% CI 92--99%) with the corresponding positive and negative likelihood ratio of 29 (95% CI 11--96) and 0.22 (95% CI 0.14--0.31). Test accuracy was independent of systolic function in a multivariate regression analysis. CONCLUSIONS 'Looking twice', once at the transmitral E wave velocity and once at pulmonary venous flow in patients with mitral regurgitation, allows accurate determination of moderately severe and severe mitral regurgitation.

Abstract
BACKGROUND Experimentally, activated macrophages have been documented to induce vascular proliferation. METHODS AND RESULTS In 21 patients (age 74+/-9 years) with extensive coronary artery disease not eligible for coronary artery bypass surgery, the effect of granulocyte-macrophage colony-stimulating factor (GM-CSF, Molgramostim) on quantitatively assessed collateral flow was tested in a randomized, double-blind, placebo-controlled fashion. The study protocol consisted of an invasive collateral flow index (CFI) measurement immediately before intracoronary injection of 40 microg of GM-CSF (n=10) or placebo (n=11) and after a 2-week period with subcutaneous GM-CSF (10 microg/kg) or placebo, respectively. CFI was determined by simultaneous measurement of mean aortic pressure (P(ao), mm Hg), distal coronary occlusive pressure (P(occl), mm Hg; using intracoronary sensor guidewires), and central venous pressure (CVP, mm Hg): CFI=(P(occl)-CVP)/(P(ao)-CVP). CFI, expressing collateral flow during coronary occlusion relative to normal antegrade flow during vessel patency, changed from 0.21+/-0.14 to 0.31+/-0.23 in the GM-CSF group (P<0.05) and from 0.30+/-0.16 to 0.23+/-0.11 in the placebo group (P=NS). The treatment-induced difference in CFI was +0.11+/-0.12 in the GM-CSF group and -0.07+/-0.12 in the placebo group (P=0.01). ECG signs of myocardial ischemia during coronary balloon occlusion occurred in 9 of 10 patients before and 5 of 10 patients after GM-CSF treatment (P=0.04), whereas they were observed in 5 of 11 patients before and 8 of 11 patients after placebo (P=NS). CONCLUSIONS This first clinical study investigating the potential of GM-CSF to improve collateral flow in patients with coronary artery disease documents its efficacy in a short-term administration protocol.
