Clinical impact of sex differences and procedural setting in transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) is a well-established treatment for symptomatic patients with aortic stenosis. Yet, the impact of sex differences and public vs. private procedural setting on TAVI outcomes remain uncertain.

Long-term outcomes of cardiogenic shock and cardiac arrest complicating ST-elevation myocardial infarction according to timing of occurrence.

Aims: Cardiogenic shock (CS) and cardiac arrest (CA) are serious complications in ST-elevation myocardial infarction (STEMI) patients, with lack of long-term data according to their timing of occurrence. This study sought to determine the incidence and relationship between the timing of occurrence and prognostic impact of CS and CA complicating STEMI in the long-term follow-up.

Methods And Results: We conducted a retrospective analysis of consecutive STEMI patients treated between 2004 and 2017.

Association of colchicine use with cardiovascular and limb events in peripheral artery disease: Insights from a retrospective cohort study.

Background And Aims: Colchicine has demonstrated efficacy in treating coronary artery disease, but its efficacy in peripheral artery disease (PAD) remains uncertain. This study aims to address this gap in knowledge.

Methods: A retrospective cohort study was conducted using the TriNetX Network, selecting patients with lower limb PAD between January 1, 2011, and January 1, 2024.

Cerebrovascular Events in Patients Undergoing Transfemoral Transcatheter Aortic Valve Implantation: A Pooled Patient-Level Study.

Background: Cerebrovascular events remain one of the most devastating complications of transcatheter aortic valve implantation (TAVI). Data from real-world contemporary cohorts on longitudinal trends and outcomes remain limited. The aim of this study was to assess incidence, temporal trends, predictors, and outcomes of cerebrovascular events following transfemoral TAVI.

Learning Curve for In-Hospital Mortality of Transcatheter Aortic Valve Replacement: Insights from the Brazilian National Registry.

Background: Robust data on the learning curve (LC) of transcatheter aortic valve replacement (TAVR) are lacking in developing countries.

Objective: To assess TAVR's LC in Brazil over time.

Methods: We analyzed data from the Brazilian TAVR registry from 2008 to 2023.

Final 36-Month Outcomes from the Multicenter DynamX Study Evaluating a Novel Thin-Strut Novolimus-Eluting Coronary Bioadaptor System and Supporting Preclinical Data.

Background: The DynamX Novolimus-Eluting Coronary Bioadaptor System ( Bioadaptor) has uncaging elements that disengage after the resorption of the polymer coating, aiming to restore vessel function in the treated segment and to avoid long-term adverse outcomes associated with the permanent caging of the coronary artery seen with conventional stenting.

Methods: This prospective, multicenter, single-arm first-in-human study enrolled 50 patients in Belgium and Italy who were treated with the DynamX Bioadaptor. Eligible patients had lesions in coronary arteries measuring between 2.

Risk Burden of Cancer in Patients Treated With Abbreviated Dual Antiplatelet Therapy After PCI: Analysis of Multicenter Controlled High-Bleeding Risk Trials.

Background: Oncological patients with coronary artery disease face an elevated risk of hemorrhagic and ischemic events following percutaneous coronary intervention. Despite medical guidelines recommending minimal dual antiplatelet therapy (DAPT) duration for patients with cancer, dedicated data on abbreviated DAPT in this population is lacking. This study aims to evaluate the occurrence of ischemic and hemorrhagic events in patients with cancer compared with other high-bleeding risk individuals.

Growth Hormone Secretagogue Receptor (GHSR) Signaling in the Ventral Tegmental Area (VTA) Mediates Feeding Produced by Chronic Social Defeat Stress in Male Mice.

Ghrelin, a hormone secreted by the stomach, binds to the growth hormone secretagogue receptor (GHSR) in various brain regions to produce a number of behavioral effects that include increased feeding motivation. During social defeat stress, ghrelin levels rise in correlation with increased feeding and potentially play a role in attenuating the anxiogenic effects of social defeat. One region implicated in the feeding effects of ghrelin is the ventral tegmental area (VTA), a region implicated in reward seeking behaviors, and linked to social defeat in mice.

Concordance between vessel-specific and vascular territory coronary functional assessment: A comparison of quantitative flow ratio and myocardial perfusion scintigraphy.

Background: Quantitative flow ratio (QFR) and myocardial perfusion scintigraphy (MPS) are utilized for assessing coronary artery disease (CAD) significance. We aimed to analyze their concordance and prognostic impact.

Aims: We aimed to analyze the concordance between QFR and MPS and their risk stratification.

Percutaneous Strategies in Structural Heart Diseases: Focus on Chronic Heart Failure.

Background: Central Illustration : Percutaneous Strategies in Structural Heart Diseases: Focus on Chronic Heart Failure Transcatheter devices for monitoring and treating advanced chronic heart failure patients. PA: pulmonary artery; LA: left atrium; AFR: atrial flow regulator; TASS: Transcatheter Atrial Shunt System; VNS: vagus nerve stimulation; BAT: baroreceptor activation therapy; RDN: renal sympathetic denervation; F: approval by the American regulatory agency (FDA); E: approval by the European regulatory agency (CE Mark).

Background: Innovations in devices during the last decade contributed to enhanced diagnosis and treatment of patients with cardiac insufficiency.

Myocardial Injury After Transcatheter Mitral Valve Replacement Versus Surgical Reoperation.

This study aimed to evaluate the incidence and clinical implications of myocardial injury, as determined by cardiac biomarker increase, in patients who underwent mitral bioprosthesis dysfunction treatment with transcatheter mitral valve replacement (TMVR) versus surgical mitral valve replacement reoperation (SMVR-REDO). Between 2014 and 2023, 310 patients with mitral bioprosthesis failure were included (90 and 220 patients for TMVR and SMVR-REDO, respectively). Multivariable analysis and propensity score matching were performed to adjust for the intergroup differences in baseline characteristics.

Impact of periprocedural myocardial injury after transcatheter aortic valve implantation on long-term mortality: a meta-analysis of Kaplan-Meier derived individual patient data.

Background: Periprocedural myocardial injury (PPMI) frequently occurs after transcatheter aortic valve implantation (TAVI), although its impact on long-term mortality is uncertain.

Methods: We performed a pooled analysis of Kaplan-Meier-derived individual patient data to compare survival in patients with and without PPMI after TAVI. Flexible parametric models with B-splines and landmark analyses were used to determine PPMI prognostic value.

B-type natriuretic peptide and N-terminal Pro-B-type natriuretic peptide in severe aortic stenosis: a comprehensive literature review.

B-type natriuretic peptide (BNP) and N-terminal pro-BNP (NT-pro BNP) are cardiac biomarkers that are released in response to increased ventricular and atrial wall stress. Aortic stenosis (AS) leads to hemodynamic changes and left ventricular hypertrophy and may be associated with natriuretic peptide levels. Several studies have shown that increased natriuretic peptide levels are correlated with AS severity and can predict the need for intervention.
