RESUMEN
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.

Pulmonary hypertension (PH) is a common condition in patients with left heart disease (LHD) that is highly relevant for morbidity and mortality. While post-capillary in nature, the pathophysiology of PH in patients with LHD (heart failure/cardiomyopathy, valvular heart disease; other: congenital/acquired) is complex, and decisions about management strategies are challenging. Recently, the updated European Society of Cardiology/European Respiratory Society guidelines on the diagnosis and treatment of PH revisited hemodynamic definitions and the sub-classification of post-capillary PH, and provided numerous new recommendations on the diagnosis and management of PH associated with various types of LHD. Here, we review several novel aspects that focus on: (a) updated hemodynamic definitions, including the distinction between isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH); (b) the pathogenesis of PH-LHD, considering various components contributing to PH, such as pulmonary congestion, vasoconstriction, and vascular remodeling; (c) the prognostic relevance of PH and hemodynamic markers; (d) the diagnostic approach to PH-LHD; (e) management strategies in PH-LHD, distinguishing between targeting the underlying left heart condition, the pulmonary circulation, and/or impaired right ventricular function. In conclusion, precise clinical and hemodynamic characterization and detailed phenotyping are essential for prognostication and the management of patients with PH-LHD.

BACKGROUND: Appropriate and timely anticoagulant therapy with vitamin K antagonists (VKAs) or non-vitamin K oral antagonists (NOACs) is essential for stroke prevention in non-valvular atrial fibrillation (NVAF). Comparative data regarding effectiveness and safety for edoxaban vs phenprocoumon, the predominant VKA in Germany, are scarce. OBJECTIVES: The study evaluates effectiveness and safety of edoxaban vs phenprocoumon in NVAF patients in a German real-world setting. METHODS: German statutory health insurance claims data of the Institute for Applied Health Research Berlin (InGef) Research Database from 2014 until 2019 were analyzed. In NVAF patients, new users of edoxaban and phenprocoumon were compared to assess effectiveness (stroke/systemic embolism (SE)) and safety (bleeding) during therapy. Hazard ratios (HR) were estimated through multiple outcome-specific cox proportional hazard models adjusting for baseline characteristics. Outcomes of geriatric patients were analyzed in subgroup analyses. RESULTS: Between 2015 and 2018, 7,975 and 13,319 NVAF patients newly initiated treatment with edoxaban or phenprocoumon. After adjusting for baseline confounders, the risk of stroke/SE (HR: 0.85, 95% CI: 0.70-1.02) was numerically but not significantly lower, while the risk of major bleeding (HR: 0.69, 95% CI: 0.58-0.81) was significantly lower for edoxaban. In the geriatric subgroups, homogenous results compared to the main analysis were obtained. CONCLUSION: The results of this real-world analysis indicated better effectiveness and safety outcomes in patients with NVAF initiating edoxaban treatment compared to phenprocoumon. The findings confirm that the beneficial effects observed in the pivotal ENGAGE AF-TMI 48 trial can also be achieved in real-world use of edoxaban.
RESUMEN
PURPOSE: Despite developments in both imaging and microbiological techniques, the final diagnosis of IE often remains challenging. In this single-center cohort study, we aimed to identify the specific indications for request of 18F-FDG-PET/CT in clinical practice and to evaluate the diagnostic benefit of this nuclear imaging technique. METHODS: A total of 235 patients with possible (n = 43) or definite (n = 192) IE according to the revised Duke criteria were prospectively studied from July 2013 until December 2016. Echocardiography was generally used as the primary cardiac imaging technique. All patients were treated by a multidisciplinary Endocarditis Team. Diagnostics with 18F-FDG-PET/CT were undertaken on request by at least one member of the multidisciplinary team when overall diagnostics were inconclusive. RESULTS: In 20 patients, 18F-FDG-PET/CT scan was performed for additional diagnostic evaluation. Hereof, 15 patients had a history of implanted cardiac prosthetic material. In six patients with definite IE, the use of 18F-FDG-PET/CT was helpful for further clarification of the diagnosis. In one patient with possible IE, the diagnosis could be reclassified to definite IE. In addition, one case of vertebral osteomyelitis as well as upper and lower leg abscesses and knee empyema were detectable as extracardiac foci. Furthermore, 18F-FDG-PET/CT leads to a modification of the management in five patients. CONCLUSION: Our findings support the utility of 18F-FDG-PET/CT as an adjunctive diagnostic tool especially in the evaluation of prosthetic valve-/cardiac device-related IE and for the detection of extracardiac foci in some cases. However, due to remaining limitations also of this imaging technique, a multidisciplinary clinical evaluation still remains the essential basis for the diagnostic assessment.

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.

B cells are increasingly coming into play in the pathogenesis of multiple sclerosis (MS). Here, we screened peripheral blood mononuclear cells (PBMC) from patients with clinically isolated syndrome (CIS), MS, other non-inflammatory neurological, inflammatory neurological or autoimmune diseases, and healthy donors for their B cell reactivity to CNS antigen using the enzyme-linked immunospot technique (ELISPOT) after 96 h of polyclonal stimulation. Our data show that nine of 15 patients with CIS (60.0%) and 53 of 67 patients with definite MS (79.1%) displayed CNS-reactive B cells, compared to none of the control donors. The presence of CNS-reactive B cells in the blood of the majority of patients with MS or at risk to develop MS along with their absence in control subjects suggests that they might be indicative of a B cell-dependent subpopulation of the disease.

PURPOSE: Evaluate optic nerve sheath and pial diameters (ONSD, ONPD) via sonography and computed tomography (CT) after out-of-hospital cardiac arrest (CA) and to compare their prognostic significance with other imaging and laboratory biomarkers. MATERIALS AND METHODS: A prospective observational study enrolling patients after successful resuscitation between December 2017 and August 2021. ONSD and ONPD were measured with sonography. Additionally, ONSD, and also grey-to-white ratio at basal ganglia (GWRBG) and cerebrum (GWRCBR), were assessed using CT. Lactate and neuron specific enolase (NSE) blood levels were measured. RESULTS: Sonographically measured ONSD and ONPD yielded no significant difference between survival and non-survival (p values ≥0.4). Meanwhile, CT assessed ONSD, GWRBG, GWRCBR, and NSE levels significantly differed regarding both, survival (p values ≤0.005) and neurological outcome groups (p values ≤0.04). For survival prognosis, GWRBG, GWRCBR, and NSE levels appeared as excellent predictors; in predicting a good neurological outcome, NSE had the highest accuracy. CONCLUSIONS: CT diagnostics, in particular GWRBG and GWRCBR, as well as NSE as laboratory biomarker, appear as excellent outcome predictors. Meanwhile, our data lead us to recommend caution in utilizing sonography assessed ONSD and ONPD for prognostic decision-making post-CA.

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.

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.
RESUMEN
BACKGROUND: In Germany, a total of 38 547 heart valve procedures were performed in 2022. With a growing number of patients undergoing the surgical and interventional implantation of heart valves, the incidence of prosthetic endocarditis is also rising. METHODS: We summarize the current state of the prophylaxis, diagnosis, and treatment of prosthetic endocarditis in a selective review of the literature. RESULTS: Prosthetic endocarditis accounts for 10-30% of all cases of endocarditis. As its echocardiographic and microbiologic findings are often less specific than those of native endocarditis, its diagnosis now increasingly relies on alternative imaging modalities such as F-18-FDG PET-CT. Anti-infective and surgical treatment are made more difficult by biofilm formation on the prosthetic valve and the frequent formation of perivalvular abscesses. CONCLUSION: Increased awareness of this clinical entity in the outpatient setting will promote the earlier initiation of appropriate diagnostic studies. Proper diagnostic evaluation is an essential prerequisite for the early detection and timely treatment of prosthetic endocarditis, with the goal of preventing progressive destruction and thus improving the outcome. Preventive and educative measures should be intensified, and certified, multidisciplinary endocarditis teams should be established. Antibiotic prophylaxis is now given much more restrictively than in earlier years; the risk of infection must be weighed against the potential development of both individual and collective resistance to antibiotic drugs.

Background: Previous trials investigating antithrombotic therapy with a direct oral anticoagulant (DOAC) and a P2Y12 inhibitor after percutaneous coronary intervention (PCI), termed dual therapy, allowed a short period of triple therapy including a DOAC, a P2Y12 inhibitor, and aspirin. Aims: This study aimed to determine whether discontinuation of aspirin on the first post-procedural day is safe or causes ischemic events. Methods: Ischemic and bleeding events during hospitalization were investigated retrospectively in all patients treated with dual therapy (DOAC + P2Y12 inhibitor, designated as group 1) or triple therapy (DOAC + P2Y12 inhibitor+aspirin, designated as group 2) from day 1 after PCI at our center. Results: Of 4,564 consecutive PCI procedures, 1,059 (23.2%) had an indication for OAC. Of these, 322 met the inclusion criteria for group 1 and 62 for group 2. Baseline characteristics, CHA2DS2-VASc and HAS-BLED scores showed no relevant differences between the two groups, and the main indication for DOAC therapy was atrial fibrillation in both groups. Approximately » of patients were treated for acute coronary syndrome. The mean length of post-procedural hospitalization was 2.1 ± 2.5 and 2.2 ± 3.0 days in group 1 and 2, respectively (p = 0.305). One patient per group suffered a TIA (p = 0.297). There were no other ischemic events and no statistically significant differences in bleeding events. A subgroup analysis of cases hospitalized for ≥2 post-procedural days (group 1: 100 cases, mean 4.4 ± 3.4 days vs. group 2: 25 cases, mean 4.0 ± 4.1 days) confirmed these results. Conclusion: The initiation of dual therapy and thus discontinuation of aspirin on the first postprocedural day appears to be safe with respect to short-term ischemic events in a real-world population. Almost » of patients undergoing PCI have an indication for OAC, highlighting the relevance of this issue.
RESUMEN
Patients with left heart disease (LHD) often display pulmonary hypertension (PH), which impacts morbidity and mortality. The pathophysiology of PH is complex and entails pulmonary congestion due to elevated left-sided filling pressures, pulmonary vasoconstriction as well as vascular remodeling. The recent ESC/ERS Guidelines on pulmonary hypertension updated the hemodynamic definitions of pulmonary hypertension in general, and the subclassification of post-capillary PH. This review summarizes recent advances in the diagnostic work-up and management strategies of PH associated with LHD. Specifically, we summarize revisited hemodynamic definitions and the characteristics of isolated post-capillary PH (IpcPH) and combined post- and pre-capillary PH (CpcPH). Furthermore, we review the current knowledge on the pathogenesis of PH-LHD, the prognostic relevance of hemodynamic parameters, and the management strategies, differentiating between treatment of the underlying left heart disease and therapies targeting the pulmonary circulation. The article emphasises the need for precise diagnostic work-up and individualized treatment strategies in patients with PH-LHD.

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.

OBJECTIVE: After transcatheter aortic valve implantation (TAVI), the optimal regimen of anticoagulant therapy in patients with an additional indication for oral anticoagulation remains a matter of debate. This study investigates the efficacy of direct oral anticoagulants (DOACs) versus vitamin K antagonists (VKAs) in patients after TAVI in a real-world population. METHODS: The German Aortic Valve RegistrY (GARY) is a prospective, multicentre registry enrolling patients undergoing invasive treatment for aortic valve disease. From January 2011 to December 2019, 1 41 790 patients from 92 hospitals in Germany were enrolled. Anticoagulatory treatment regimens were assessed at hospital discharge for patients after TAVI procedures. All-cause mortality and the combined endpoint 'cardiac and cerebrovascular events' containing myocardial infarction, stroke, transient ischaemic attack, aortic prosthesis reintervention and all-cause mortality in the first year after TAVI were examined by treatment regimen. RESULTS: Of 45 598 patients (mean age 80.7±5.7 years, 49.3% males) undergoing TAVI, 16 974 patients (37.2%) received an anticoagulant regimen that included VKA or DOAC. Hereof, the majority of patients were prescribed VKA (n=11 333, 66.8%) compared with DOAC (n=5641, 33.2%) with an increase of DOAC use from 9.4% in 2011 to 69.9% in 2019. During the 1-year follow-up, the absolute event rates per 100 person-years for all-cause mortality and the combined endpoint cardiac and cerebrovascular events were 1.9 and 1.3 for VKA-treated and 1.7 and 1.2 for DOAC-treated patients, respectively. After adjustment for baseline confounders, all-cause mortality (HR 0.95, 95% CI 0.88 to 1.01, p=0.114) and cardiac and cerebrovascular event-free survival (HR 0.93, 95% CI 0.86 to 1.01, p=0.071) did not differ significantly between VKA and DOAC groups. CONCLUSIONS: This study supports evidence of the efficacy of DOAC use after TAVI in patients with an indication for oral anticoagulation.

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.

AIMS: This study sought to investigate current anticoagulatory treatment patterns and clinical outcome in patients undergoing transcatheter mitral valve repair (MitraClip). METHODS AND RESULTS: In a retrospective study of a German claims database (InGef research database), anticoagulatory treatment regimens were assessed using any drug prescription post discharge within the first 90 days after MitraClip procedure. Clinical events between 30 days and 6 months were examined by treatment regime. The study population comprised 1342 patients undergoing MitraClip procedure between 2014 and 2018. 22.4% received antiplatelet monotherapy, 20.8% oral anticoagulation (OAC) plus antiplatelet therapy, 19.4% OAC monotherapy, 11.7% dual antiplatelet therapy, 2.8% triple therapy and 21.0% did not receive any anticoagulatory drugs. 63% of patients with OAC received non-vitamin-K antagonist oral anticoagulants (NOAC). A total of 168 patients were newly prescribed OAC after MitraClip, of whom 12 patients (7.1%) had no diagnosis of atrial fibrillation or venous thromboembolism. 40% of patients with OAC prior to MitraClip did not have any OAC after MitraClip. The adjusted risk of all-cause mortality was significantly increased in patients with no anticoagulatory treatment (HR 3.84, 95% CI 2.33-6.33, p < 0.0001) when compared to antiplatelet monotherapy whereas the other regimes were not significantly different. CONCLUSIONS: This large real-world data analysis demonstrates a heterogeneous spectrum of prescriptions for anticoagulant therapies after MitraClip. Considering relevant differences in clinical outcome across treatment groups, major effort is warranted for controlled trials in order to establish evidence-based recommendations on anticoagulatory treatment after percutaneous mitral valve repair.

PURPOSE: Baroreflex activation therapy has favorable effects in heart failure patients. We report the results of a single-center study of baroreflex activation therapy in heart failure with reduced ejection fraction including cardiopulmonary exercise testing for the first time to show the effect on exercise capacity. METHODS: A total of 17 patients were treated with baroreflex activation therapy. Eligibility criteria were the New York Heart Association class ⩾III and ejection fraction ⩽35% on guideline-directed medical and device therapy. The New York Heart Association class, quality of life, and 6-min hall walk distance were assessed in all patients. Twelve patients underwent cardiopulmonary exercise testing before and 8.9 ± 6.4 months after initiation of baroreflex activation therapy. RESULTS: The New York Heart Association class and 6-min hall walk distance improved after baroreflex activation therapy, while quality of life remained stable. Weight-adapted peak oxygen uptake increased significantly from 10.1 (8.2-12.9) ml/min/kg to 12.1 (10.4-14.6) ml/min/kg (p = 0.041). Maximal heart rate was stable. Maximal oxygen pulse increased from 9.7 (5.5-11.3) to 9.9 (7.1-12.1) ml/heartbeat (p = 0.047) in 10 patients with low maximal oxygen pulse at baseline (<16.5 ml/heartbeat). There was no significant change in maximal oxygen pulse in the whole cohort. Ventilatory efficiency remained stable. CONCLUSION: Weight-adapted peak oxygen uptake improved after baroreflex activation therapy, pointing to an enhanced exercise capacity. Ventilatory efficiency and heart rate did not change, while oxygen pulse increased in patients with low oxygen pulse at baseline, indicating an improvement in circulatory efficiency, that is, a beneficial effect on stroke volume and peripheral oxygen extraction.

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.
