Background
Concomitant right ventricular (RV) failure and tricuspid regurgitation (TR) are common comorbidities in patients undergoing mitral valve transcatheter edge-to-edge repair (M-TEER) and are associated with worse prognosis. Improvement of TR after M-TEER occurs frequently, however determinants of this course are poorly understood. This study aimed to analyze serum biomarkers that are differentially regulated in patients with TR and to identify biomarkers predictive of the course of TR after M-TEER.
Methods and Results
Biomarker expression was analyzed in 242 prospectively included patients undergoing M-TEER. Patients with moderate-to-severe TR had significant comorbidities (median EuroSCORE II 5.2 in patients with severe TR, 4.9 in moderate TR, 3.2 in no/mild TR; p = 0.002) and a large number of biomarkers was upregulated including IGFBP-2 (1.4-fold in severe TR compared to no/mild TR, p = 0.005). Echocardiographic follow-up 3 months after M-TEER was carried out in 99 patients. RV reverse remodeling (RVRR) as defined by improvement of concomitant TR by at least one grade and/or RV diameter downsizing of at least 10% compared to baseline was seen in 50 patients (50.5%). IGFBP-2 (Odds Ratio 2.078) and presence of chronic pulmonary disease (Odds Ratio 15.341) proved independent predictors of non-development of RVRR within 3 months after M-TEER.
Conclusions
In patients undergoing M-TEER with concomitant moderate or severe TR, numerous cardiometabolic biomarkers including IGFBP-2 are upregulated. Higher levels of IGFBP-2 at baseline are independently associated with persistent TR and/or RV dilation after M-TEER.

To perform a bibliometric analysis of publications of arrhythmogenic right ventricular cardiomyopathy (ARVC) from 1981 to 2023 to summarize the current publications and explore frontiers on this topic.
Methods
We integrated the scientific publications on ARVC in the Web of Science (WOS) Core Collection database from January 1981 to September 2023, using the retrieval strategy of medical subject headings combined with keywords. We focused on articles and reviews that were published in English. Relevant information such as the journal and publisher, the title, authors, organizations, abstract, keywords, published date, and number of citations, were collected. Bibliometric analysis was performed and visualized by the R software and Microsoft Excel.
Results
The results revealed a total of 4792 records related to ARVC from the WOS database, and 2992 original articles or reviews which were selected for bibliometric analysis. There were 79 countries and regions, 3724 research institutions, and 12 157 scholars who have published in this topic. The number of scientific publications of ARVC increased year-by-year, with an annual growth rate of 12.12%. We also investigated the top 10 contributing countries, organizations with affiliations, most influential researchers, highest-cited articles, and highest-frequency keywords. In addition, the most active areas of research on ARVC included that of fatal complications, molecular pathological mechanisms, diagnosis, therapy, and prognosis respectively according to the keywords trend analysis.
Conclusions
Our study reports the publication landscape of ARVC during the past four decades based on bibliometric analysis. This study provides a deeper understanding of the published literature on ARVC.

Aim
A recent European Heart Rhythm Association (EHRA) practical guide provides guidance on the use of novel digital devices for heart rhythm analysis using either electrocardiogram (ECG) or photoplethysmography (PPG) technology for the diagnosis of atrial fibrillation (AF). This survey assesses physicians' preferences to use digital devices in patients with possible AF and their impact on clinical decision-making.
Methods and Results
Participants of the DAS-CAM III initiated and distributed an online survey assessing physician preferences in using digital devices for the management of AF in different clinical scenarios. A total of 505 physicians (median age: 38 [IQR 33–46] years) from 30 countries completed the survey. A third of respondents were electrophysiologists, the others were cardiologists, cardiology residents, or general practitioners. Electrophysiologists were more likely to have experience with both ECG-based (92% vs. 68%, p < 0.001) and PPG-based (60% vs. 34%, p < 0.001) digital devices. The initial diagnostic approach to each scenario (symptomatic low-risk, symptomatic high-risk, or asymptomatic high-risk patient) was heterogeneous. Electrophysiologists preferred intermittent single-lead ECG monitoring to traditional Holter ECGs to screen for AF. Both electrophysiologists and non-electrophysiologists would rarely use PPG-based devices to diagnose and screen for AF (8.2%–9.8%). Electrophysiologists and non-electrophysiologists use ECG-based technology to confirm PPG-documented tracings suggestive of AF.
Conclusion
While PPG-based digital devices are rarely used for diagnosis and screening for AF, intermittent ECG-based digital devices are beginning to be implemented in clinical practice. More education on the potential of novel digital devices is required to achieve diagnostic pathways as suggested by the EHRA practical guide.

Background
The optimal duration of dual antiplatelet therapy (DAPT) for patients with coronary multi-vessel disease (MVD) who have received drug-eluting stents (DES) remains unclear.
Hypothesis and Methods
The Dual Antiplatelet Therapy in Patients with Coronary Multi-Vessel Disease (DAPT-MVD) study is a multicenter, open-label, randomized controlled trial designed to assess the efficacy and safety of extended DAPT in MVD patients 12 months following DES implantation. We plan to enroll 8250 patients across approximately 100 sites in China. Participants will be randomized in a 1:1 ratio to receive either extended DAPT (75 mg clopidogrel plus 75–150 mg aspirin daily) or monotherapy (75–150 mg aspirin daily) beyond 12 months post-DES implantation. The follow-up period will last at least 12 months, with all potential endpoints adjudicated by a blinded Clinical Events Committee. The primary endpoint is major adverse cardiovascular and cerebrovascular events (MACCE), including cardiovascular death, nonfatal myocardial infarction, or nonfatal stroke.
Results
As of April 2024, a total of 8250 participants have been enrolled in the study. The mean age of the enrolled patients was 60.5 ± 8.8years, with 5753 (69.7%) being men.
Conclusions
The DAPT-MVD study is the first large-scale trial to evaluate the efficacy and safety of prolonged DAPT with clopidogrel plus aspirin beyond 12 months after DES implantation in MVD patients. The trial will provide novel insights into the optimal duration of DAPT for MVD patients (ClinicalTrials. gov ID: NCT04624854. Registered on 10/27/2020).

Background
Orthostatic hypotension (OH) is associated with different cardiovascular diseases, however, the association between OH and coronary slow flow (CSF) has never been evaluated before.
Materials and Methods
Chest pain patients who underwent coronary angiography (CAG) and with normal coronary arteries in our department from January 1st, 2022 to August 31st, 2023 were retrospectively enrolled. Patients were divided into the CSF group and the normal blood flow (NBF) group. Relative clinical information, laboratory test results as well as the results of CAG were collected and analyzed. Both uni-variable and multi-variable logistic regression analyses were used to evaluate the association between OH and CSF in these patients.
Results
Four thousand six hundred and twenty-seven patients underwent CAG and 655 patients had normal coronary arteries. In which, sixty-nine patients were diagnosed with CSF while 586 patients were diagnosed with NBF. Uni-variable analysis revealed that higher body weight index, faster heart rate in sitting position, accompanied with chronic kidney disease, did not take Antidiabetic therapy, higher level of aspartate transaminase, uric acid, triglyceride, total cholesterol, ApoB1, low-density lipoprotein cholesterol, homocysteine, B-type natriuretic peptide as well as OH are the risk factors for CSF in these patients. Multi-variable logistic regressing analysis further demonstrated that OH was the independent risk factor for predicting CSF in these patients.
Conclusions
Our finding suggests OH might be a useful predictor for CSF in patients with chest pain but normal coronary arteries.

Background
Since 2010, all non-VA hospitals performing cardiac surgeries and percutaneous interventions in Washington State have participated in the Cardiac Care Outcomes Assessment Program (COAP), a data-driven, physician-led collaborative quality improvement (QI) collaborative. Prior literature has demonstrated QI programs such as COAP can avert avoidable utilization such as hospital readmissions. However, it is unknown whether such improvements translate into economic benefits.
Hypothesis
This study compared downstream healthcare costs between patients undergoing cardiac interventions for coronary artery disease (CAD) at hospitals that were and were not participating in COAP.
Methods
Post hoc analysis of Medicare administrative and claims data examined 2.5 million randomly selected deidentified beneficiaries receiving a percutaneous coronary intervention or coronary artery bypass grafting between 2013 and 2020. Total costs were defined as all reimbursements paid by Medicare for up to 5 years following cardiac intervention. Because all non-VA hospitals in Washington State participated in COAP, we compared respective groups of patients receiving intervention in Washington State with all non-Washington states, adjusting for patient demographics and comorbidity. To model costs, we applied a multipart estimator, which distinguishes the impact of QI program participation due to survival and utilization while accounting for censoring.
Results
Total 5-year downstream costs were $3861 lower (95% confidence interval [CI] = $1794 to $5741) among patients receiving cardiac intervention at COAP-exposed hospitals. Lower costs were largely driven by lower utilization during calendar quarters where death was not observed.
Conclusions
Participation in this state-wide cardiac quality improvement program was associated with economic benefits in patients receiving intervention for CAD.

Background
This prospective, randomized trial aimed to compare the efficacy and safety of different intravenous diuretic regimens in acute decompensated heart failure (ADHF) patients.
Methods
ADHF patients were enrolled and randomized into three groups: continuous intravenous furosemide infusion (cIV), bolus furosemide injection (bI), and furosemide plus hypertonic saline solution (HSS). Clinical outcomes were assessed over 48 h.
Results
In a study involving 1276 patients admitted for ADHF, three therapeutic regimens (T × 1, T × 2, and T × 3) were compared. T × 1 administered an 80 mg furosemide intravenous bolus infusion twice daily to 479 patients, while T × 2 involved a continuous 16-h infusion of 160 mg furosemide daily to 420 patients. T × 3 treated 377 patients with 160 mg furosemide combined with 150 mL of HSS containing 1.95% NaCl over 30 min. Yet, overall changes in renal markers such as BUN, Na, K, and serum creatinine did not differ significantly. Analysis of prespecified study endpoints revealed notable variations in hospitalization length among the treatment arms. T × 1 demonstrated a significantly shorter hospital stay (3.7 days) compared to T × 2 (6.6 days) and T × 3 (7.9 days). Conversely, alterations in serum creatinine at 48 h, overall changes in serum creatinine, body weight loss, and serum potassium levels did not significantly differ among the treatment groups.
Conclusion
While intravenous bolus of furosemide showed potential benefits in reducing hospitalization duration, limitations such as a small sample size and short-term observation emphasize the need for larger studies to validate these outcomes further.

Introduction
Patients with small vessels who undergo percutaneous coronary intervention (PCI) with subsequent multiple implantation of drug-eluting stents remain at a higher risk of unfavorable outcomes. In complex cases where maintaining flow to all side branches is part of contemporary practice, using two-stent techniques may be appropriate. This study aims to evaluate the efficacy of double-kissing (DK) culotte technique in comparison to culotte technique in the context of small-vessel therapy in patients with acute coronary syndrome (ACS).
Methods
This substudy of the Lower Silesia culotte Bifurcation Registry retrospectively analyzed patients who underwent ACS-PCI using DK culotte or culotte technique for bifurcation lesions in small vessels, defined as having at least one branch with a diameter of 2.75 mm or less. The primary endpoint was target lesion failure (TLF), a composite of cardiovascular death, target vessel myocardial infarction, or clinically driven target lesion revascularization (TLR) at 1-year follow-up. The secondary endpoint included major adverse cardiac events (MACE).
Results
The DK culotte group (n = 49) and the culotte group (n = 52) were compared, with 12-month follow-up showing lower TLF in the DK culotte group (8.2% vs. 19.2%, p = 0.082). Similar results were observed for TLR (6.1% vs. 13.5%; p = 0.161), stent restenosis (4.1% vs. 9.6%; p = 0.203), and MACE (18.4% vs. 25%; p = 0.344).
Conclusion
For bifurcation lesions with a small-diameter artery, the DK culotte technique may reduce TLF and MACE compared to the culotte technique. However, given the limited sample size and the absence of statistical significance, these findings remain preliminary and require further investigation.

Introduction
The benefit of complete revascularization in diabetic patients with myocardial infarction remains unclear. this study aims to find the optimal strategy of total vascular repair for diabetic patients with acute myocardial infarction.
Methods
In an analysis of a cohort, we assigned diabetic patients with myocardial infarction who were undergoing percutaneous coronary intervention (PCI) of the culprit lesion to receive either staged complete revascularization of nonculprit lesions or to receive no further revascularization in Madani Hospital (Tabriz, Iran). Functionally significant nonculprit lesions were identified either by angiography. The primary outcome was rates of readmission, cardiac deaths, nonfatal myocardial re-infarction, and overall mortality at 1 year.
Results
In our center, a total of 1186 patients underwent primary-PCI treatment, among which 521 were diagnosed with diabetes. Ultimately, 393 patients were selected for inclusion in the study. Within this cohort, 271 individuals (68.9%) underwent repair of only the culprit vessels (group 1), while 122 individuals (31.1%) received a comprehensive staged restoration of the vessels (group 2). During this time, group 1 in comparison with group 2 experienced 204 (75.3%) versus 97 (79.5%) cases of readmission, 48 (17.7%) versus 8 (6.5%) instances of cardiac death, 22 (8.1%) versus 18 (14.7%) occurrences of nonfatal myocardial re-infarction. Notably, the incidence of cardiac death in group 2 were significantly lower than that in group 1 (p ≤ 0.05).
Conclusions
For individuals diagnosed with diabetes, staged complete revascularization demonstrated a lower frequency of readmission, cardiac deaths, nonfatal myocardial reinfarction, and overall mortality, in contrast to revascularization that targeted only the culprit lesion.
