RESUMO
BACKGROUND: About half of patients with severe aortic stenosis present with concomitant coronary artery disease. The optimal timing of percutaneous coronary intervention (PCI) and transcatheter aortic valve implantation (TAVI) in patients with severe aortic stenosis and concomitant coronary artery disease remains unknown. STUDY DESIGN: The TAVI PCI trial is a prospective, international, multicenter, randomized, two-arm, open-label study planning to enroll a total of 986 patients. It is designed to investigate whether the strategy "angiography-guided complete revascularization after (within 1-45 days) TAVI" is non-inferior to the strategy "angiography-guided complete revascularization before (within 1-45 days) TAVI" using the Edwards SAPIEN 3 or 3 Ultra Transcatheter Heart Valve™ in patients with severe aortic stenosis and concomitant coronary artery disease. Patients are randomized in a 1:1 ratio to one of the two treatment strategies. The primary end point is a composite of all-cause death, non-fatal myocardial infarction, ischemia-driven revascularization, rehospitalization (valve- or procedure-related including heart failure), or life-threatening/disabling or major bleeding at 1 year. CONCLUSIONS: The TAVI PCI trial tests the hypothesis that the strategy "PCI after TAVI" is non-inferior to the strategy "PCI before TAVI" in patients with severe aortic stenosis and concomitant coronary artery disease.
RESUMO
AIMS: Aims were to evaluate (1) reclassification of patients from heart failure with mildly reduced (HFmrEF) to reduced (HFrEF) ejection fraction when an EF = 40% was considered as HFrEF, (2) role of EF digit bias, ie, EF reporting favouring 5% increments; (3) outcomes in relation to missing and biased EF reports, in a large multinational HF registry. METHODS AND RESULTS: Of 25,154 patients in the European Society of Cardiology (ESC) HF Long-Term registry, 17% had missing EF and of those with available EF, 24% had HFpEF (EF≥50%), 21% HFmrEF (40%-49%) and 55% HFrEF (<40%) according to the 2016 ESC guidelines´ classification. EF was "exactly" 40% in 7%, leading to reclassifying 34% of the HFmrEF population defined as EF = 40% to 49% to HFrEF when applying the 2021 ESC Guidelines classification (14% had HFmrEF as EF = 41% to 49% and 62% had HFrEF as EF≤40%). EF was reported as a value ending with 0 or 5 in â¼37% of the population. Such potential digit bias was associated with more missing values for other characteristics and higher risk of all-cause death and HF hospitalization. Patients with missing EF had higher risk of all-cause and CV mortality, and HF hospitalization compared to those with recorded EF. CONCLUSIONS: Many patients had reported EF = 40%. This led to substantial reclassification of EF from old HFmrEF (40%-49%) to new HFrEF (≤40%). There was considerable digit bias in EF reporting and missing EF reporting, which appeared to occur not at random and may reflect less rigorous overall care and worse outcomes.

BACKGROUND: Acute coronary syndromes (ACS) occurring on rest days have been associated with higher mortality, but the current literature remains inconsistent in this regard. This study included ACS patients presenting with acute decompensated heart failure (ADHF) investigating the relationship between time of coronary catheterization and outcomes. METHODS: Analyses were performed from the prospective, multicentric Special Program University Medicine Acute Coronary Syndromes and Inflammation (SPUM-ACS) Cohort. Patients were divided into two groups according to time of coronary catheterization on either workdays (Monday, 00:00 to Friday, 23:59) or rest days (Saturday, 00:00 to Sunday, 23:59 and public holidays). ADHF was defined by Killip Class III or IV upon presentation. Patients were followed over 1 year. RESULTS: Out of 4787 ACS patients enrolled in the SPUM-ACS Cohort, 207 (4.3%) presented with ADHF. 52 (25.1%) and 155 (74.9%) patients underwent coronary angiography on rest days or workdays, respectively. Baseline characteristics were similar among these groups. ACS patients with ADHF showed increased 1-year mortality on rest days (34.6% vs. 17.4%, p-value = 0.009). After correction for baseline characteristics, including the GRACE 2.0 Score, rest day presentation remained a significant predictor for 1-year mortality (adjusted hazard ratio = 2.42 [95% confidence interval: 1.14-5.17], p-value = 0.022). CONCLUSIONS: One-year all-cause mortality was high in ACS patients with ADHF and doubled for patients admitted on rest days. The present data support the association of a rest day effect and long-term patient survival and indicate a need for further investigations.

BACKGROUND: Left atrial appendage closure (LAAC) represents an alternative to oral anticoagulation for stroke prevention in patients with non-valvular atrial fibrillation (AF). While transoesophageal echocardiography is the current standard for guiding LAAC procedures, several centers have employed fluoroscopic guidance alone. However, data on long-term outcomes are lacking. METHODS: A total of 536 patients with AF undergoing LAAC and with available data on long-term follow-up were included in the retrospective, single-center analysis. Outcomes of patients undergoing fluoroscopy-guided LAAC were compared with those undergoing echocardiography guided LAAC. Time-dependent analysis was performed with the Kaplan-Meier method. RESULTS: A total of 234 (44%) and 302 (56%) patients were treated with echocardiography and fluoroscopy guidance, respectively. Baseline characteristics did not differ between the two groups. Procedural success rates were high in both groups (97% of fluoroscopy vs. 98% of echocardiography guided procedures; p = 0.92) and rates of relevant peri-device leaks (p = 0.50) and device-related thrombus formation (p = 0.22) did not differ between groups. Median clinical follow-up time was 48 (IQR 19-73) months. Rates of all-cause mortality (p = 0.15, HR 0.83, CI 0.64-1.07) and stroke (p = 0.076, HR 2.23, CI 0.90-5.54) were comparable among groups. CONCLUSION: LAAC with fluoroscopy guidance alone is equally safe and leads to similar clinical outcome compared to LAAC with additional echocardiography guidance.

CONTEXT.: Autopsies can reveal clinically undiagnosed diseases. However, the frequency of first diagnoses at autopsy and their association with clinically known risk factors are not well understood because of lack of systematic analyses addressing this topic. OBJECTIVE.: To perform a large retrospective cohort analysis on the frequency of clinically undiagnosed postmortem findings and correlate these with patients' risk factors. DESIGN.: Six hundred forty-eight consecutive and complete autopsies of adults (age >18 years), performed in the University Hospital Zurich, Switzerland, during a 3-year time period were retrospectively analyzed. Clinical diagnoses and postmortem findings were compared in order to identify clinically undiagnosed lesions and clarify their correlation with common risk factors. RESULTS.: In 633 of 648 patients (98%), at least one clinically undiagnosed finding was identified at autopsy. The most common nonneoplastic entities were bronchopneumonia (198; 31%), coronary artery disease (155; 24%) and acute or subacute myocardial infarction (94; 15%), and the most common malignancies were prostate cancer in men (14; 2.2%), followed by kidney cancer (10; 1.5%), gastrointestinal stromal tumor (10; 1.5%), and lung carcinoma (9; 1.4%) in both genders. Clinically undiagnosed cardiac amyloidosis was demonstrated in 8% (52 of 648) of patients and was significantly associated with age, hypertension, chronic kidney disease, coronary artery disease, and hypertensive cardiomyopathy. CONCLUSIONS.: Autopsy is a useful investigation for the detection of clinically undiagnosed entities. In our cohort, cardiac amyloidosis showed the highest number of underlying risk factors, but was clinically underdiagnosed. Our findings underline the necessity of improved clinical detection of cardiac amyloidosis, especially in light of emerging therapeutic options. Moreover, we characterize the most common entities prone to clinical underdiagnosis.
RESUMO
Background: Cardiac resynchronization therapy (CRT) has evolved into an established therapy for patients with chronic heart failure and a wide QRS complex. Data on long-term outcomes over time are scarce and the criteria for implantation remain a subject of investigation. Methods: An international, multicenter, retrospective registry includes 2275 patients who received CRT between 30 November 2000 and 31 December 2019, with a mean follow-up of 3.6 ± 2.7 years. Four time periods were defined, based on landmark trials and guidelines. The combined endpoint was a composite of all-cause mortality, heart transplantation, or left ventricular assist device implantation. Results: The composite endpoint occurred in 656 patients (29.2%). The mean annual implantation rate tripled from 31.5 ± 17.4/year in the first period to 107.4 ± 62.4/year in the last period. In the adjusted Cox regression analysis, the hazard ratio for the composite endpoint was not statistically different between time periods. When compared to sinus rhythm with left bundle branch block (LBBB), a non-LBBB conduction pattern (sinus rhythm: HR 1.51, 95% CI 1.12-2.03; atrial fibrillation: HR 2.08, 95% CI 1.30-3.33) and a QRS duration below 130 ms (HR 1.64, 95% CI 1.29-2.09) were associated with a higher hazard ratio. Conclusions: Despite innovations, an adjusted regression analysis revealed stable overall survival over time, which can at least partially be explained by a shift in patient characteristics.
RESUMO
AIMS: Tricuspid regurgitation (TR) is commonly observed in patients with severe left-sided valvular heart disease (VHD). This study sought to assess TR frequency, management and outcome in this population. METHODS AND RESULTS: Among 6883 patients with severe native left-sided VHD or previous left-sided valvular intervention enrolled in the EURObservational Research Programme prospective VHD II survey, moderate or severe TR was very frequent in patients with severe mitral VHD (30% when mitral stenosis, 36% when mitral regurgitation [MR]), especially in patients with secondary MR (46%), and rare in patients with severe aortic VHD (4% when aortic stenosis, 3% when aortic regurgitation). An increase in TR grade was associated with a more severe clinical presentation and a poorer 6-month survival (p < 0.0001). Rates of concomitant tricuspid valve (TV) intervention at the time of left-sided heart valve surgery were high at the time of mitral valve surgery (50% when mitral stenosis, 41% when MR). Concordance between class I indications (patients with severe TR) for concomitant TV surgery at the time of left-sided valvular heart surgery according to guidelines and real-practice decision-making was very good (88% overall, 95% in patients operated on for MR). CONCLUSION: In this large international prospective survey among patients with severe left-sided VHD, moderate/severe TR was frequent in patients with mitral valve disease and was associated with a poorer outcome as TR grade increased. In patients with severe TR, compliance to guidelines for class I indications for concomitant TV surgery at the time of left-sided heart valve surgery was very good.

BACKGROUND: The effects of non-pharmaceutical interventions in the prevention of cardiovascular diseases (CVD) in older adults remains unclear. Therefore, the aim was to investigate the effect of 2000 IU/day of vitamin D3, omega-3 fatty acids (1 g/day), and a simple home strength exercise program (SHEP) (3×/week) on lipid and CVD biomarkers plasma changes over 3 years, incident hypertension and major cardiovascular events (MACE). METHODS: The risk of MACE (coronary heart event or intervention, heart failure, stroke) was an exploratory endpoint of DO-HEALTH, incident hypertension and change in biomarkers were secondary endpoints. DO-HEALTH is a completed multicentre, randomised, placebo-controlled, 2 × 2 × 2 factorial design trial enrolling 2157 Europeans aged ≥70 years. RESULTS: Participants' median age was 74 [72, 77] years, 61.7% were women, 82.5% were at least moderately physically active, and 40.7% had 25(OH)D < 20 ng/mL at baseline. Compared to their controls, omega-3 increased HDL-cholesterol (difference in change over 3 years: 0.08 mmol/L, 95% CI 0.05-0.10), decreased triglycerides (-0.08 mmol/L, (95%CI -0.12 to -0.03), but increased total- (0.15 mmol/L, 95%CI 0.09; 0.2), LDL- (0.11 mmol/L, 0.06; 0.16), and non-HDL-cholesterol (0.07 mmol/L, 95%CI 0.02; 0.12). However, neither omega-3 (adjustedHR 1.00, 95%CI 0.64-1.56), nor vitamin D3 (aHR 1.37, 95%CI 0.88-2.14), nor SHEP (aHR 1.18, 95%CI 0.76-1.84) reduced risk of MACE or incident hypertension compared to control. CONCLUSION: Among generally healthy, active, and largely vitamin D replete, older adults, treatment with omega-3, vitamin D3, and/or SHEP had no benefit on MACE prevention. Only omega-3 supplementation changed lipid biomarkers, but with mixed effects. TRIAL REGISTRATION CLINICALTRIALS. GOV IDENTIFIER: NCT01745263.

AIMS OF THE STUDY: Systemic amyloidoses are rare protein-folding diseases with heterogeneous, often nonspecific clinical presentations. To better understand systemic amyloidoses and to apply state-of-the-art diagnostic pathways and treatment, the interdisciplinary Amyloidosis Network was founded in 2013 at University Hospital Zurich. In this respect, a registry was implemented to study the characteristics and life expectancy of patients with amyloidosis within the area covered by the network. Patient data were collected retrospectively for the period 2005-2014 and prospectively from 2015 onwards. METHODS: Patients aged 18 years or older diagnosed with any subtype of systemic amyloidosis were eligible for inclusion if they were treated in one of the four referring centres (Zurich, Chur, St Gallen, Bellinzona). Baseline data were captured at the time of diagnosis. Follow-up data were assessed half-yearly for the first two years, then annually. RESULTS: Between January 2005 and March 2020, 247 patients were screened, and 155 patients with confirmed systemic amyloidosis were included in the present analysis. The most common amyloidosis type was light-chain (49.7%, n = 77), followed by transthyretin amyloidosis (40%, n = 62) and amyloid A amyloidosis (5.2%, n = 8). Most patients (61.9%, n = 96) presented with multiorgan involvement. Nevertheless, single organ involvement was seen in all types of amyloidosis, most commonly in amyloid A amyloidosis (75%, n = 6). The median observation time of the surviving patients was calculated by the reverse Kaplan-Meier method and was 3.29 years (95% confidence interval [CI] 2.33-4.87); it was 4.87 years (95% CI 3.14-7.22) in light-chain amyloidosis patients and 1.85 years (95% CI 1.48-3.66) in transthyretin amyloidosis patients, respectively. The 1-, 3- and 5-year survival rates were 87.0% (95% CI 79.4-95.3%), 68.5% (95% CI 57.4-81.7%) and 66.0% (95% CI 54.6-79.9%) respectively for light-chain amyloidosis patients and 91.2% (95% CI 83.2-99.8%), 77.0% (95% CI 63.4-93.7%) and 50.6% (95% CI 31.8-80.3%) respectively for transthyretin amyloidosis patients. There was no significant difference between the two groups (p = 0.81). CONCLUSION: During registry set-up, a more comprehensive work-up of our patients suffering mainly from light-chain amyloidosis and transthyretin amyloidosis was implemented. Survival rates were remarkably high and similar between light-chain amyloidosis and transthyretin amyloidosis, a finding which was noted in similar historic registries of international centres. However, further studies are needed to depict morbidity and mortality as the amyloidosis landscape is changing rapidly.

IMTRODUCTION: The high-risk population of patients with cardiovascular (CV) disease or risk factors (RF) suffering from COVID-19 is heterogeneous. Several predictors for impaired prognosis have been identified. However, with machine learning (ML) approaches, certain phenotypes may be confined to classify the affected population and to predict outcome. This study aimed to phenotype patients using unsupervised ML technique within the International Postgraduate Course Heart Failure Registry for patients hospitalized with COVID-19 and Cardiovascular disease and/or RF (PCHF-COVICAV). MATERIAL AND METHODS: Patients from the eight centres with follow-up data available from the PCHF-COVICAV registry were included in this ML analysis (K-medoids algorithm). RESULTS: Out of 617 patients included into the prospective part of the registry, 458 [median age: 76 (IQR:65-84) years, 55% male] were analyzed and 46 baseline variables, including demographics, clinical status, comorbidities and biochemical characteristics were incorporated into the ML. Three clusters were extracted by this ML method. Cluster 1 (n = 181) represents mainly women with the least number of overall comorbidities and cardiovascular RF. Cluster 2 (n = 227) is characterized mainly by men with non-CV conditions and less severe symptoms of infection. Cluster 3 (n=50) mainly represents men with the highest prevalence of cardiac comorbidities and RF, more extensive inflammation and organ dysfunction with the highest 6-month all-cause mortality risk. CONCLUSIONS: The ML process has identified three important clinical clusters from hospitalized COVID-19 CV and/or RF patients. The cluster of males with severe CV disease, particularly HF, and multiple RF presenting with increased inflammation had a particularly poor outcome.
RESUMO
AIMS: Iron deficiency (ID) is common in patients with heart failure (HF) and is associated with poor outcomes, regardless of anaemia status. Iron supplementation has been demonstrated to improve exercise capacity and quality of life in patients with HF with an ejection fraction <50% and ID. This survey aimed to provide data on real-world practices related to ID screening and management. METHODS AND RESULTS: We designed and distributed an online survey (23 questions) regarding ID screening and management in the HF setting. Overall, 256 cardiologists completed the survey (59.8% male, mostly between 30 and 50 years). The majority of physicians defined ID according to the most recent HF recommendations (98.4%) and reported screening for ID in more than half of their patients (68.4%). However, only 54.3% of the respondents performed periodic screening (every 6 months to 1 year). A total of 93.0% of participants prescribed and/or administered iron supplementation, using intravenous iron as the preferred method of administration (86.3%). After iron supplementation, 96.1% of the respondents reassessed ID, most frequently at 3-6 months (67.6%). Most physicians (93.8%) perceived ID as an underestimated comorbidity in HF. Cardiologists' age, training status, subspecialty and work setting (academic vs. non-academic hospitals) were associated with heterogeneity in the answers. CONCLUSIONS: The results of this survey highlight the need for more consistent strategies of ID screening and treatment for patients with HF.

Implantable devices form an integral part of the management of patients with heart failure (HF) and provide adjunctive therapies in addition to cornerstone drug treatment. Although the number of these devices is growing, only few are supported by robust evidence. Current devices aim to improve haemodynamics, improve reverse remodelling, or provide electrical therapy. A number of these devices have guideline recommendations and some have been shown to improve outcomes such as cardiac resynchronization therapy, implantable cardioverter-defibrillators and long-term mechanical support. For others, more evidence is still needed before large-scale implementation can be strongly advised. Of note, devices and drugs can work synergistically in HF as improved disease control with devices can allow for further optimization of drug therapy. Therefore, some devices might already be considered early in the disease trajectory of HF patients, while others might only be reserved for advanced HF. As such, device therapy should be integrated into HF care programmes. Unfortunately, implementation of devices, including those with the greatest evidence, in clinical care pathways is still suboptimal. This clinical consensus document of the Heart Failure Association (HFA) and European Heart Rhythm Association (EHRA) of the European Society of Cardiology (ESC) describes the physiological rationale behind device-provided therapy and also device-guided management, offers an overview of current implantable device options recommended by the guidelines and proposes a new integrated model of device therapy as a part of HF care.

AIM: The RESHAPE-HF2 trial is designed to assess the efficacy and safety of the MitraClip device system for the treatment of clinically important functional mitral regurgitation (FMR) in patients with heart failure (HF). This report describes the baseline characteristics of patients enrolled in the RESHAPE-HF2 trial compared to those enrolled in the COAPT and MITRA-FR trials. METHODS AND RESULTS: The RESHAPE-HF2 study is an investigator-initiated, prospective, randomized, multicentre trial including patients with symptomatic HF, a left ventricular ejection fraction (LVEF) between 20% and 50% with moderate-to-severe or severe FMR, for whom isolated mitral valve surgery was not recommended. Patients were randomized 1:1 to a strategy of delivering or withholding MitraClip. Of 506 patients randomized, the mean age of the patients was 70 ± 10 years, and 99 of them (20%) were women. The median EuroSCORE II was 5.3 (2.8-9.0) and median plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) was 2745 (1407-5385) pg/ml. Most patients were prescribed beta-blockers (96%), diuretics (96%), angiotensin-converting enzyme inhibitors/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors (82%) and mineralocorticoid receptor antagonists (82%). The use of sodium-glucose cotransporter 2 inhibitors was rare (7%). Cardiac resynchronization therapy (CRT) devices had been previously implanted in 29% of patients. Mean LVEF, left ventricular end-diastolic volume and effective regurgitant orifice area (EROA) were 31 ± 8%, 211 ± 76 ml and 0.25 ± 0.08 cm2, respectively, whereas 44% of patients had mitral regurgitation severity of grade 4+. Compared to patients enrolled in COAPT and MITRA-FR, those enrolled in RESHAPE-HF2 were less likely to have mitral regurgitation grade 4+ and, on average, HAD lower EROA, and plasma NT-proBNP and higher estimated glomerular filtration rate, but otherwise had similar age, comorbidities, CRT therapy and LVEF. CONCLUSION: Patients enrolled in RESHAPE-HF2 represent a third distinct population where MitraClip was tested in, that is one mainly comprising of patients with moderate-to-severe FMR instead of only severe FMR, as enrolled in the COAPT and MITRA-FR trials. The results of RESHAPE-HF2 will provide crucial insights regarding broader application of the transcatheter edge-to-edge repair procedure in clinical practice.

BACKGROUND: Catecholaminergic polymorphic ventricular tachycardia (CPVT) is a rare, inherited heart rhythm disorder that is caused by variants in genes responsible for cardiac calcium homeostasis. The aim of this study was to analyze different genotype-specific clinical manifestations of this disease. METHODS AND RESULTS: We analyzed five CPVT cases from our institution in the context of specific patient characteristics and genotype-phenotype correlations. In this cohort, three of the index patients were male. The median age at diagnosis was 11 (11-30) years, and median age at disease onset was 12 (12-33) years. Four index patients suffered from syncope, while one female index patient suffered from out-of-hospital cardiac arrest. Two index patients experienced concomitant atrial flutter and atrial fibrillation. Three patients received an implantable cardioverter defibrillator and one patient received an event recorder. All index patients had causative genetic variants in the RYR2-gene. CONCLUSIONS: This study presents various phenotypic presentations of patients with CPVT harboring different pathogenic variants in the RYR2 gene, some of which have not previously been described in published studies. Syncope was the most prevalent symptom on admission. Adjustment of beta-blocker therapy may be necessary due to side effects. Moreover, our work further highlights the common occurrence of atrial tachyarrhythmias in these patients.
