PATHFINDER-CHD: prospective registry on adults with congenital heart disease, abnormal ventricular function, and/or heart failure as a foundation for establishing rehabilitative, prehabilitative, preventive, and health-promoting measures: rationale, aims, design and methods.

BACKGROUND: Adults with congenital heart defects (ACHD) globally constitute a notably medically underserved patient population. Despite therapeutic advancements, these individuals often confront substantial physical and psychosocial residua or sequelae, requiring specialized, integrative cardiological care throughout their lifespan. Heart failure (HF) is a critical challenge in this population, markedly impacting morbidity and mortality. AIMS: The primary aim of this study is to establish a comprehensive, prospective registry to enhance understanding and management of HF in ACHD. Named PATHFINDER-CHD, this registry aims to establish foundational data for treatment strategies as well as the development of rehabilitative, prehabilitative, preventive, and health-promoting interventions, ultimately aiming to mitigate the elevated morbidity and mortality rates associated with congenital heart defects (CHD). METHODS: This multicenter survey will be conducted across various German university facilities with expertise in ACHD. Data collection will encompass real-world treatment scenarios and clinical trajectories in ACHD with manifest HF or at risk for its development, including those undergoing medical or interventional cardiac therapies, cardiac surgery, inclusive of pacemaker or ICD implantation, resynchronization therapy, assist devices, and those on solid organ transplantation. DESIGN: The study adopts an observational, exploratory design, prospectively gathering data from participating centers, with a focus on patient management and outcomes. The study is non-confirmatory, aiming to accumulate a broad spectrum of data to inform future hypotheses and studies. PROCESSES: Regular follow-ups will be conducted, systematically collecting data during routine clinical visits or hospital admissions, encompassing alterations in therapy or CHD-related complications, with visit schedules tailored to individual clinical needs. ASSESSMENTS: Baseline assessments and regular follow-ups will entail comprehensive assessments of medical history, ongoing treatments, and outcomes, with a focus on HF symptoms, cardiac function, and overall health status. DISCUSSION OF THE DESIGN: The design of the PATHFINDER-CHD Registry is tailored to capture a wide range of data, prioritizing real-world HF management in ACHD. Its prospective nature facilitates longitudinal data acquisition, pivotal for comprehending for disease progression and treatment impacts. CONCLUSION: The PATHFINDER-CHD Registry is poised to offer valuable insights into HF management in ACHD, bridging current knowledge gaps, enhancing patient care, and shaping future research endeavors in this domain.

Multiparametric Monitoring of Disease Progression in Contemporary Patients with Wild-Type Transthyretin Amyloid Cardiomyopathy Initiating Tafamidis Treatment.

BACKGROUND: Recently, a disease modifying therapy has become available for transthyretin amyloid cardiomyopathy (ATTR-CM). A validated monitoring concept of treatment is lacking, but a current expert consensus recommends three clinical domains (clinical, biomarker and ECG/imaging) assessed by several measurable features to define disease progression. METHODS: We retrospectively analyzed data of wild-type ATTR-CM patients initiating tafamidis therapy assessed within our local routine protocol at baseline and 6-months follow-up with respect to the frequency of values beyond the proposed thresholds defining disease progression. Additionally, associations of cardiac magnetic resonance (CMR) tomography with clinical domains were examined within a subgroup. RESULTS: Sixty-two ATTR-CM patients were included (88.7% male, mean age 79 years). In total, 16.1% of patients had progress in the clinical and functional domain, 33.9% in the biomarker domain and 43.5% in the imaging/electrocardiography (ECG) domain, with the latter driven by deterioration of the diastolic dysfunction grade and global longitudinal strain. In total, 35.5% of patients showed progress in none, 35.5% in one, 29.0% in two and no patient in three domains, the latter indicating overall disease progression. A subgroup analysis of twenty-two patients with available baseline and follow-up CMR data revealed an increase in CMR-based extracellular volume by more than 5% in 18.2% of patients, with no significant correlation with progress in one of the clinical domains. CONCLUSIONS: We provide first frequency estimates of the markers of disease progression according to a recent expert consensus statement, which might help refine the multiparametric monitoring concept in patients with ATTR-CM.

Impact of rapid sequential combination therapy on distinct haemodynamic measures in newly diagnosed pulmonary arterial hypertension.

AIMS: In pulmonary arterial hypertension (PAH), upfront combination therapy with ERA and PDE5i is associated with a reduction in morbidity and mortality events and improves standard haemodynamics, but data remain limited. Aims of this study were (i) to capture detailed haemodynamic effects of rapid sequential dual combination therapy in patients with newly diagnosed PAH; (ii) to monitor the impact of treatment initiation on clinical variables and patients' risk status, and (iii) to compare the treatment effect in patients with 'classical PAH' and 'PAH with co-morbidities'. METHODS: Fifty patients (median age 57 [42-71] years, 66% female) with newly diagnosed PAH (76% idiopathic) were treated with a PD5i/sGC-S or ERA, followed by addition of the respective other drug class within 4 weeks. All patients underwent repeat right heart catheterization (RHC) during early follow-up. RESULTS: At early repeat RHC (7 ± 2 months), there were substantial reductions in mean pulmonary artery pressure (mPAP: 52.2 ± 13.5 to 39.0 ± 10.6 mmHg; -25.3%), and pulmonary vascular resistance (PVR: 12.1 ± 5.7 to 5.8 ± 3.1 WU; -52.1%), and an increase in cardiac index (2.1 ± 0.4 to 2.7 ± 0.7 mL/min/m2; +32.2%) (all P < 0.05). Haemodynamic improvements correlated with improved clinical parameters including 6-min walking distance (336 ± 315 to 389 ± 120 m), NTproBNP levels (1.712 ± 2.024 to 506 ± 550 ng/L, both P < 0.05) and WHO-FC at 12 months, resulting in improved risk status, and were found in patients with few (n = 37) or multiple cardiovascular co-morbidities (BMI > 30 kg/m2, hypertension, diabetes, coronary artery disease [≥3]; n = 13), albeit baseline PVR in PAH patients with multiple co-morbidities was lower (9.3 ± 4.4 vs. 13.1 ± 5.9 WU) and PVR reduction less pronounced compared with those with few co-morbidities (-42.7% vs. -54.7%). However, comprehensive haemodynamic assessment considering further variables of prognostic relevance such as stroke volume index and pulmonary artery compliance showed similar improvements among the two groups (SVI: +50.0% vs. +49.2%; PAC: 91.7% vs. 100.0%). Finally, the 4-strata risk assessment approach was better able to capture treatment response as compared with other approaches, particularly in patients with co-morbidities. CONCLUSIONS: Rapid sequential combination therapy with PDE5i/sGC-S and ERA substantially ameliorates cardiopulmonary haemodynamics at early follow-up in patients without, and to a lesser extent, with cardiovascular co-morbidities. This occurs in line with improvements of clinical parameters and risk status.

Thoracic aorta diameters in Marfan patients: Intraindividual comparison of 3D modified relaxation-enhanced angiography without contrast and triggering (REACT) with transthoracic echocardiography.

OBJECTIVE: To compare the measurement of aortic diameters using a novel flow-independent MR-Angiography (3D modified Relaxation-Enhanced Angiography without Contrast and Triggering (modified REACT)) and transthoracic echocardiography (TTE) in Marfan syndrome (MFS) patients. MATERIAL AND METHODS: This retrospective, single-center analysis included 46 examinations of 32 MFS patients (mean age 37.5 ± 11.3 years, 17 women, no prior aortic surgery) who received TTE and 3D modified REACT (ECG- and respiratory-triggering, Compressed SENSE factor 9 for acceleration of image acquisition) of the thoracic aorta. Aortic diameters (sinus of Valsalva (SV), sinotubular junction (STJ), and ascending aorta (AoA)) were independently measured by two cardiologists in TTE (leading-edge) and two radiologists in modified REACT (inner-edge, using multiplanar reconstruction). Intraclass correlation coefficient, Bland-Altman analyses, and Pearson's correlation (r) were used to assess agreement between observers and methods. RESULTS: Interobserver correlation at the SV, STJ, and AoA were excellent for both, TTE (ICC = 0.95-0.98) and modified REACT (ICC = 0.99-1.00). There was no significant difference between TTE and modified REACT for diameters measured at the SV (39.24 ± 3.24 mm vs. 39.63 ± 3.76 mm; p = 0.26; r = 0.78) and the STJ (35.16 ± 4.47 mm vs. 35.37 ± 4.74 mm; p = 0.552; r = 0.87). AoA diameters determined by TTE were larger than in modified REACT (34.29 ± 5.31 mm vs. 30.65 ± 5.64 mm; p < 0.01; r = 0.74). The mean scan time of modified REACT was 05:06 min ± 02:47 min, depending on the patient's breathing frequency and heart rate. CONCLUSIONS: Both TTE and modified REACT showed a strong correlation for all aortic levels; however, at the AoA, diameters were larger using TTE, mostly due to the limited field of view of the latter with measurements being closer to the aortic valve. Given the excellent interobserver correlation and the strong agreement with TTE, modified REACT represents an attractive method to depict the thoracic aorta in MFS patients.

Transcatheter aortic valve implantation with different self-expanding devices-a propensity score-matched multicenter comparison.

OBJECTIVE: Several supra-annular self-expanding transcatheter systems are commercially available for transcatheter aortic valve implantation (TAVI). Comparative data in large-scale multicenter studies are scant. METHODS: This study included a total of 5175 patients with severe aortic stenosis undergoing TAVI with the ACURATE neo (n = 1095), Evolut R (n = 3365), or Evolut PRO (n = 715) by a transfemoral approach at five high-volume centers. Propensity score matching resulted in 654 triplets. Outcomes are reported according to the Valve Academic Research Consortium-3 (VARC-3) consensus. RESULTS: Moderate or severe paravalvular regurgitation (PVR) occurred significantly more often in the ACURATE neo group (5.2%) than in the Evolut R (1.8%) and Evolut PRO (3.3%) groups (p = 0.003). The rates of major vascular-/access-related complications (4.6%, 3.8%, and 5.0%; p = 0.56), type 3 or 4 bleeding (3.2%, 2.1%, and 4.1%; p = 0.12), and 30-day mortality (2.4%, 2.6%, and 3.7%; p = 0.40) were comparable. The rate of new permanent pacemaker implantation (PPI) was significantly lower in the ACURATE neo group (9.5%, 17.6%, and 16.8%; p < 0.001). Independent predictors for 2-year survival were a Society of Thoracic Surgeons (STS) risk score ≥5%, diabetes mellitus, a glomerular filtration rate <30 ml/min, baseline mean transvalvular gradient ≤ 30 mm Hg, treating center, and relevant PVR. CONCLUSION: In this multicenter study, TAVI with the ACURATE neo, Evolut R, or Evolut PRO was feasible and safe. The rate of relevant PVR was more frequent after the ACURATE neo implantation, with, however, lower rates of PPI. Two-year survival was mainly driven by baseline comorbidities.

Imaging of the extracranial internal carotid artery in acute ischemic stroke: assessment of stenosis, plaques, and image quality using relaxation-enhanced angiography without contrast and triggering (REACT).

Background: In stroke magnetic resonance imaging (MRI), contrast-enhanced magnetic resonance angiography (CE-MRA) is the clinical standard to depict extracranial arteries but native MRA techniques are of increased interest to facilitate clinical practice. The purpose of this study was to assess the detection of extracranial internal carotid artery (ICA) stenosis and plaques as well as the image quality of cervical carotid arteries between a novel flow-independent relaxation-enhanced angiography without contrast and triggering (REACT) sequence and CE-MRA in acute ischemic stroke (AIS). Methods: In this retrospective, single-center study, 105 consecutive patients (65.27±18.74 years, 63 males) were included, who received a standard stroke protocol at 3T in clinical routine including Compressed SENSE (CS) accelerated (factor 4) 3D isotropic REACT (fixed scan time: 02:46 min) and CS accelerated (factor 6) 3D isotropic CE-MRA. Three radiologists independently assessed scans for the presence of extracranial ICA stenosis and plaques (including hyper-/hypointense signal) with concomitant diagnostic confidence using 3-point scales (3= excellent). Vessel quality, artifacts, and image noise of extracranial carotid arteries were subjectively scored on 5-point scales (5= excellent/none). Wilcoxon tests were used for statistical comparison. Results: Considering CE-MRA as the standard of reference, REACT provided a sensitivity of 89.8% and specificity of 95.2% for any and of 93.5% and 95.8% for clinically relevant (≥50%) extracranial ICA stenosis and yielded a to CE-MRA comparable diagnostic confidence [mean ± standard deviation (SD), median (interquartile range): 2.8±0.5, 3 (3-3) vs. 2.7±0.5, 3 (2-3), P=0.03]. Using REACT, readers detected more plaques overall (n=57.3 vs. 47.7, P<0.001) and plaques of hyperintense signal (n=12.3 vs. 5.7, P=0.02) with higher diagnostic confidence [2.8±0.5, 3 (3-3) vs. 2.6±0.7, 3 (2-3), P<0.001] than CE-MRA. After analyzing a total of 1,260 segments, the vessel quality of all segments combined [4.61±0.66 vs. 4.58±0.68, 5 (4-5) vs. 5 (4-5), P=0.0299] and artifacts [4.51±0.70 vs. 4.44±0.73, 5 (4-5) vs. 5 (4-5), P>0.05] were comparable between the sequences with REACT showing a lower image noise [4.43±0.67 vs. 4.25±0.71, 5 (4-5) vs. 4 (4-5), P<0.001]. Conclusions: Without the use of gadolinium-based contrast agents or triggering, REACT provides a high sensitivity and specificity for extracranial ICA stenosis and a potential improved depiction of adjacent plaques while yielding to CE-MRA comparable vessel quality in a large patient cohort with AIS.

Diagnostic performance of quantitative flow ratio versus fractional flow reserve and resting full-cycle ratio in intermediate coronary lesions.

BACKGROUND: Quantitative flow ratio (QFR) is a novel angiography-derived index aimed to assess the functional relevance of coronary stenoses without pressure wires and adenosine. Good diagnostic yield with the hyperemic fractional flow reserve (FFR) have been reported, while data on the comparison of QFR to non-hyperemic pressure ratios (NHPR) are scarce. METHODS: In this retrospective, observational and single-center study with a large population representative of the real practice, we assessed and compared the diagnostic performance of contrast flow (cQFR) and fixed flow (fQFR) QFR against the NHPR resting full-cyle ratio (RFR) using FFR as reference standard. RESULTS: A total of 626 lesions from 544 patients were investigated. Mean diameter stenosis, FFR, cQFR, fQFR and RFR were 44.8%, 0.842, 0.847, 0.857 and 0.912, respectively. The correlation between cQFR and FFR was stronger (r = 0.830, P < 0.001) compared to that between FFR and RFR (r = 0.777, P < 0.001) and between cQFR and RFR (r = 0.687, P < 0.001). Using FFR ≤0.80 as reference, the sensitivity, specificity, positive predictive value, negative predictive value, and overall diagnostic accuracy for cQFR were 82%, 95%, 87%, 92%, and 91%, respectively. cQFR displayed a higher area under the curve (AUC) than fQFR and RFR (0.938 vs. 0.891 vs. 0.869, P < 0.01). The good diagnostic yield of cQFR appeared to be maintained in different clinical subsets including female gender, aortic valve stenosis and atrial fibrillation, and in different anatomical subsets including focal and non-focal lesions. CONCLUSION: cQFR has a high and better diagnostic performance than the NHPR RFR in predicting FFR-based functional significance of coronary stenoses.

Surgical Procedure Time and Mortality in Patients with Infective Endocarditis Caused by Staphylococcus aureus or Streptococcus Species.

Staphylococcus aureus (SA) and Streptococcus species (SS) show different clinical manifestations in infective endocarditis (IE), but the impact on the complexity of surgical treatment remains unclear. All patients with surgically treated IE due to SA or SS between July 2013 and December 2016 were extracted from a prospectively collected, single-center registry. Data on patient characteristics, surgical procedures, and postprocedural outcomes were collected. SA-IE was more common with prosthetic valves (26.3% vs. 7.3%, p = 0.04), cardiac devices (14.3% vs. 0%, p = 0.03), previous cardiac surgery (28.6% vs. 9.8%, p = 0.03), intravenous drug abuse (14.3% vs. 0%, p = 0.03), and embolic events (57.1% vs. 26.8%, p = 0.007). Preoperative CRP was significantly higher in SA-IE (median 96.1 mg/L vs. 42.4 mg/L, p = 0.002). Otherwise, SS-IE affected more cusps/leaflets (mean 2.4 vs. 1.8, p = 0.03) and led to more valve dysfunction (83.8% vs. 54.3%, p = 0.007). Surgery times did not differ between the groups, though patients with SA spent more time in the intensive care unit (median 7 vs. 4.5 days, p = 0.04). Hospital mortality did not differ, but patients with SA-IE had unfavorable long-term survival (p = 0.001). Future studies need to be larger and focus on the mechanism behind the reduced long-term survival to mitigate the deleterious effect of SA in surgically treated patients with IE.

Implantable loop recorder for monitoring patients with congenital heart disease.

BACKGROUND: Patients with congenital heart defects (CHD) are prone to residua, sequels and complications from the underlying anomaly, where cardiac arrhythmias are one of the major causes for hospitalization, morbidity and mortality. The importance of the subcutaneous implantable loop recorder (ILR) for the detection and documentation of significant arrhythmias has increased over the last years. To date, however, there is little data on ILR use in the CHD population. METHODS: In this single center, retrospective observational study, all CHD-patients with an ILR were identified who were under care of the German Heart Center Munich between February 2015 and January 2019. The primary endpoint of the study was the detection or exclusion of significant arrhythmias during follow-up in CHD-patients who had received an ILR. The secondary endpoint was to determine whether ILR findings influenced patient management, defined as initiation or adjustment of medication, cardioversion, electrophysiologic study, catheter ablation, or implantation of cardiac implantable electronic devices (CIEDs) such as pacemakers (PM) or implantable cardioverter-defibrillators. RESULTS: An ILR was implanted in 33 CHD-patients (mean age, 43±20 years; 42.4% female) with CHD. During a mean observation period of 697±433 days, clinically relevant arrhythmias, correlating with the patients' complaints and symptoms, were detected in 19 patients (59.4%), encompassing supraventricular tachycardia (n=10), supraventricular or ventricular ectopic beats (n=10), non-sustained ventricular tachycardia (n=2), ventricular tachycardia (n=2), and bradycardia (n=2). In 9 patients (28.1%) the detected arrhythmia was considered an event requiring treatment. Treatment modalities included catheter ablation (n=5), modification of antiarrhythmic drug regime (n=2), adaptation of anticoagulation therapy (n=2), or implantation of a subcutaneous ICD (n=1). Regarding the occurrence of cardiac arrhythmias or a related need for therapeutic intervention, no significant differences were identified with respect to WHO functional class, the presence of pulmonary arterial hypertension or reduced resting peripheral oxygen saturation. CONCLUSIONS: In symptomatic CHD-patients at risk for life-threatening cardiac events, ILR has a considerable complementary diagnostic value for the detection and differentiation of benign and malignant arrhythmias. Considering the overall low risk of complications, ILR implantation should be considered in patients with CHD of any complexity who need medium or long-term arrhythmia monitoring, especially if short-term Holter monitoring cannot provide sufficient diagnostic certainty.

Contrast-Enhanced Ultrasound for the Detection of Abdominal Complications in Infective Endocarditis: First Experience From a Prospective Cohort.

Embolic events are associated with increased mortality in patients with infective endocarditis (IE). The goal of this study was to gain experience with the application of contrast-enhanced ultrasound (CEUS) in IE to detect abdominal complications. CEUS was performed in 40 patients from a prospective register of IE. CEUS was able to detect abdominal embolic events or metastatic infection in 12 patients (30%). Most commonly seen were splenic infarctions (n = 10), followed by renal infarction (n = 2), liver abscess (n = 1) and mycotic aneurysm (n = 1). Six out of 14 lesions were only detected by CEUS and not by conventional ultrasound. Abdominal complications revealed by CEUS were associated with a detectable valve vegetation (p = 0.04) and larger vegetation size (p = 0.01). In three patients, a non-IE related abdominal lesion (two hepatocellular carcinomas, one psoas hematoma) was detected. CEUS is a feasible diagnostic method in detection of abdominal complications of IE.

Inflammatory cell infiltration in left atrial appendageal tissues of patients with atrial fibrillation and sinus rhythm.

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in clinical practice and is known to be associated with significant morbidity and mortality. Previous studies suggested a link between inflammation and AF by findings of increased inflammatory markers in AF patients. However, it has not been finally clarified whether inflammation is a systemic or a local phenomenon reflecting an active inflammatory process in the heart. To address this subject, human left atrial appendage tissues were obtained from 10 patients who underwent cardiac surgery and subjected to immunohistochemical analysis. The number of inflammatory CD3-positive T cells significantly increased from patients with sinus rhythm to paroxysmal AF and persistent AF, respectively. Interestingly, in patients with persistent AF, these cells were frequently arranged in small clusters. Subsequently, the number of inflammatory CD3-positive T cells decreased and was significantly lower in patients with permanent AF than in patients with persistent AF. Inflammatory CD20-positive B cells could only be detected very occasionally in all AF subgroups and were not locatable in patients with SR. Hence, our data emphasize the potential prominent role of the cellular component of the immune system in the development and perpetuation of AF.

Determination of Electrolytes in Critical Illness Patients at Different pH Ranges: Whom Shall We Believe, the Blood Gas Analysis or the Laboratory Autoanalyzer?

INTRODUCTION: The determination of the electrolytes sodium and potassium is essential in critical care. In daily clinical practice, both the blood gas analyzer (ABG) and the laboratory autoanalyzer (AA) are generally applied. However, there is still uncertainty regarding the convergence of the prementioned assays, and data about the comparability dependent on the pH value are still lacking. MATERIALS AND METHODS: One hundred samples from intensive care unit patients with a range in pH values between 7.20 and 7.49 were evaluated in this retrospective cohort study. All patients suffered an infarct-related cardiogenic shock and were intubated and not under therapeutical hypothermia at the time of blood collection. We used scatter plots to compare different distributions of sodium and potassium values between the methods. Comparability of the analyses was assessed using the Bland-Altmann approach, and intraclass correlations (ICC) as estimates of interrater reliability were calculated. RESULTS: The mean potassium level measured on ABG was 4.33 mmol/L (SD 0.48 mmol/L), and the value obtained using the AA was 4.40 mmol/L (SD 0.55 mmol/L). A Bland-Altman comparison for total potassium measurements revealed that the limits of agreement were small (-0.241 to 0.391 mmol/L). Total ICC displayed a very good correlation of 0.949. For sodium, we found average values of 140 mmol/L (SD 5.20 mmol/L) in the AA and 140 mmol/L (SD 5.80 mmol/L) in the ABG assessment. Contrarily, the Bland-Altman comparison for sodium displayed that the 95% limits of agreement were very wide (-5.99 to 6.59 mmol/L) for total measurements as well as in every pH subgroup. Total ICC only reached a value of 0.830. CONCLUSION: Data from our single-center study indicate that urgent and vital decisions based on potassium measurements can be made by trusting the value obtained on the ABG machine irrespective of pH values.

Prominent right ventricular mass in a young patient with a history of classic testicular seminoma: a case report.

BACKGROUND: The incidence of intracardiac masses is generally low. In most cases, the formation of a thrombus represents the principal diagnosis in clinical practice. The differential diagnosis mainly includes primary tumours of the heart as well as intracardiac metastases. Testicular cancer is a rare malignancy, accounting for approximately 1% of all male tumours. Cardiac metastasis of a seminoma is extremely rare. CASE SUMMARY: A 30-year-old man with a history of a classic seminoma of the right testis was referred to our university hospital from an outside clinic. Transthoracic echocardiography showed a large space-occupying mass in the right ventricle (4.0 cm × 4.5 cm × 5.5 cm) attached to the apex and septum. Cardiac magnetic resonance imaging confirmed the finding of a 5.5 cm × 3.5 cm lesion without freely movable appendage or obstruction of the right ventricular outflow tract. Tissue characterization by T1- and T2-weighted black blood imaging revealed a signal behaviour comparable to pulmonary metastases. Additionally, positron emission tomography (PET) with 250 MBq induced 18-fluorodeoxyglucose (18F-FDG) as part of a re-staging showed significant FDG-uptake. Thus, the final diagnosis of an intracardiac metastasis of the testicular seminoma was made, and the patient was treated with cisplatin, etoposide, and bleomycin chemotherapy according to the current guidelines. A repeat trans-thoracic echocardiogram (TTE) performed 2 weeks later already demonstrated a significant reduction of the metastasis with a diameter of 3.3 cm × 3.0 cm. DISCUSSION: In the past few years, multimodality imaging has become essential in the diagnostic evaluation of cardiac disease. In order to improve the diagnostic accuracy, a modern approach should preferably contain the integration of different imaging modalities. Cardiac magnetic resonance imaging as well as 18F-FDG-PET/computed tomography helped us reach the aetiological diagnosis of an intracardiac metastasis and to initiate prompt treatment.

Non-Vitamin K Oral Anticoagulants in Comparison to Phenprocoumon in Geriatric and Non-Geriatric Patients with Non-Valvular Atrial Fibrillation.

Geriatric characteristics such as high age, multi-morbidity, polypharmacy and frailty are common in patients with atrial fibrillation (AF). In a retrospective study using a German claims database, effectiveness (ischaemic stroke/systemic embolism) and safety (intracerebral, gastrointestinal and major extracranial bleeding) were compared in patients with non-valvular AF starting non-vitamin K oral antagonists (NOACs) (apixaban, dabigatran and rivaroxaban) and phenprocoumon. Cox proportional hazards models were used to calculate adjusted hazard ratios, and interaction terms of the treatment group and geriatric status (defined by age ≥75 years, frailty, ≥ 4 co-morbidities and polypharmacy) were entered into the model. A total of 42,562 and 27,939 patients initiated NOAC and phenprocoumon treatment (mean age 74 years ± 11, 51% male) with a follow-up time of 147,785 person-years. Note that 52.9% of patients were elderly, 50.8% were frail, 37.0% were co-morbid and 46.5% had polypharmacy. NOAC use was not associated with effectiveness and gastrointestinal bleeding, neither in geriatric nor in non-geriatric patients. The hazard of major extracranial and intracranial bleeding was significantly decreased for NOAC use, with similar risk reduction in geriatric and non-geriatric patients: major extracranial bleeding 0.70 (95% confidence interval [CI], 0.56-0.87) to 0.73 (95% CI, 0.60-0.89) for the geriatric groups and 0.71 (95% CI, 0.56-0.93) to 0.76 (0.59-0.98) for the non-geriatric groups (p-values for interaction > 0.6); and intracranial bleeding 0.52 (95% CI, 0.39-0.69) to 0.59 (95% CI, 0.47-0.73) for the geriatric groups and 0.54 (95% CI, 0.37-0.79) to 0.65 (95% CI, 0.49-0.86) for the non-geriatric groups (p-values for interaction > 0.2). Hence, NOACs showed similar effectiveness and superior safety in geriatric and non-geriatric patients.

Minimally invasive direct coronary artery bypass graft surgery versus percutaneous coronary intervention of the LAD: costs and long-term outcome.

OBJECTIVE: Outcomes and treatment costs for coronary artery disease involving the left anterior descending coronary artery (LAD) are influenced by the type of treatment, which can be either isolated minimally invasive revascularization of the LAD using the internal thoracic artery (ITA) (MIDCAB) or percutaneous coronary intervention (PCI) on the LAD. This retrospective study sought to evaluate long-term survival, freedom from re-intervention and cost analysis after MIDCAB compared to PCI on the LAD. METHODS: Between 2006 and 2012, from a total of 561 patients, 106 consecutive patients with LAD stenosis underwent a MIDCAB procedure whereas 100 patients underwent elective PCI. Urgent and emergent cases were excluded from the present study (n = 355). Detailed analysis of the outcome data was performed for both groups. A Kaplan-Meier survival estimation with up to 10-year follow-up was applied for both groups for survival analysis and freedom from re-intervention. RESULTS: There were no statistically significant differences in terms of clinically relevant baseline characteristics. The outcome in the MIDCAB group was superior regarding long-term overall survival, accounting for 100% versus 92.8% at 1 year, 98.5% versus 82.1% at 6 years and 79.6% versus 61.5% at 10 years (Log Rank (Mantel-Cox) p = 0.011) and freedom from re-intervention at 10 years (97.2% vs. 86.7%, Log Rank (Mantel-Cox) p = 0.001). Intensive care unit (ICU) stay (p = 0.020) and total hospital stay (p<0.001) were significantly longer in the MIDCAB group, which was also associated with higher in-hospital costs (10,879 € vs. 4009 €, p<0.001). CONCLUSIONS: Whereas patients undergoing MIDCAB remained longer on ICU and in hospital, causing higher costs, this procedure was associated with a significantly lower incidence of repeat revascularization and significantly lower mortality compared to PCI on the LAD.

[Different Symptoms and Course of Coronary Heart Disease in Men and Women]. / Koronare Herzerkrankung ­ Unterschiede in Symptomatik und Verlauf bei Männern und Frauen.

According to the federal statistical office, cardiovascular disorders are still the leading cause of death in Germany. Chronic ischemic heart disease and acute myocardial infarction are the most important subgroups. In addition to evidence-based and personalized medicine, in recent years gender medicine has been established as an independent research area. Gender differences are evident in the majority of prevalent diseases, including cardiovascular disorders. The following article provides an insight into the diagnostically and therapeutically specific aspects of coronary heart disease in men and women.

The Correlation between the Virus- and Brain Antigen-Specific B Cell Response in the Blood of Patients with Multiple Sclerosis.

There is a largely divergent body of literature regarding the relationship between Epstein-Barr virus (EBV) infection and brain inflammation in multiple sclerosis (MS). Here, we tested MS patients during relapse (n = 11) and in remission (n = 19) in addition to n = 22 healthy controls to study the correlation between the EBV- and brain-specific B cell response in the blood by enzyme-linked immunospot (ELISPOT) and enzyme-linked immunosorbent assay (ELISA). Cytomegalovirus (CMV) was used as a control antigen tested in n = 16 MS patients during relapse and in n = 35 patients in remission. Over the course of the study, n = 16 patients were untreated, while n = 33 patients received immunomodulatory therapy. The data show that there was a moderate correlation between the frequencies of EBV- and brain-reactive B cells in MS patients in remission. In addition we could detect a correlation between the B cell response to EBV and disease activity. There was no evidence of an EBV reactivation. Interestingly, there was also a correlation between the frequencies of CMV- and brain-specific B cells in MS patients experiencing an acute relapse and an elevated B cell response to CMV was associated with higher disease activity. The trend remained when excluding seronegative subjects but was non-significant. These data underline that viral infections might impact the immunopathology of MS, but the exact link between the two entities remains subject of controversy.
