Article Synopsis
  • Intra-atrial shunts are linked to a higher risk of embolic strokes, and this study compares outcomes of shunt occlusion between younger (≤50 years) and older (>50 years) patients with a history of paradoxical embolism.
  • The study analyzed data from 187 patients who underwent shunt occlusion from 2013 to 2023, revealing that older patients had more cardiovascular risk factors but similar shunt characteristics and procedural outcomes compared to younger patients.
  • Follow-up results showed low recurrence rates of arterial embolism and no significant outcome differences between high-volume and low-volume shunts in older patients, suggesting similar safety and efficacy for both age groups.

Article Synopsis
  • Percutaneous interventional left atrial appendage occlusion (LAAO) is a proven method for preventing strokes in patients with atrial fibrillation (AF) and has been evaluated in a study involving 149 patients at a Berlin hospital from 2016 to 2022.
  • The study compared two types of devices used in LAAO: single-occlusive plug-type (SOPT) and dual-occlusive disc-type (DODT), noting that while DODT procedures took longer, both had successful implantation with low rates of complications and no hospital deaths.
  • After six months, findings indicated that SOPT had a higher rate of device-related thrombus formation compared

Introduction: There is a lack of real-world data directly comparing different valve prostheses for transaortic valve replacement (TAVR). We aimed to compare early clinical outcomes at 30-days between the self-expandable Portico valve (Abbott) with the balloon-expandable Edwards Sapien 3 valve (Edwards Lifesciences) (ES3).

Methods: Out of 1,901 patients undergoing TAVR between January 2018 and December 2021, all patients who received either Portico valve or ES3 valve via transfemoral TAVR were matched using nearest-neighbor (1:1) propensity scoring.

Background: Patients diagnosed with Marfan syndrome or a related syndrome require frequent aorta monitoring using imaging techniques like transthoracic echocardiography (TTE) and computed tomography (CT). Accurate aortic measurement is crucial, as even slight enlargement (>2 mm) often necessitates surgical intervention. The 2022 ACC/AHA guideline for Aortic Disease Diagnosis and Management includes updated imaging recommendations.

Aims: Coronary microevaginations (CMEs) represent an outward bulge of coronary plaques and have been introduced as a sign of adverse vascular remodelling following coronary device implantation. However, their role in atherosclerosis and plaque destabilization in the absence of coronary intervention is unknown. This study aimed to investigate CME as a novel feature of plaque vulnerability and to characterize its associated inflammatory cell-vessel-wall interactions.

Article Synopsis
  • Patients with Marfan syndrome are at risk of serious complications like aortic dissection and require regular monitoring with imaging techniques such as CT and echocardiography.
  • This study compares aortic measurements from whole-heart CT and transthoracic echocardiography (TTE) in 95 patients, assessing their effectiveness for diagnosis and follow-up over two years.
  • Results showed that while both methods correlate well, TTE tends to overestimate aortic diameters more frequently, suggesting that whole-heart CT may be a better option for accurate monitoring of aortic enlargement.

Aims: Although the number of patients suffering from heart failure with preserved ejection fraction (HFpEF) increases, the routine diagnosis remains a challenge. In the absence of a pathognomonic sign for HFpEF or specific treatment strategies, a prognosis-based characterization of suspected patients remains promising for both the risk stratification of the patients and a disease definition. The Heart Failure Association (HFA) of the European Society of Cardiology has introduced an algorithm with different levels of likelihood regarding the diagnosis of HFpEF, the HFA-PEFF score.

Background: In patients with de novo acute heart failure (AHF) requiring veno-arterial extracorporeal membrane oxygenation (VA-ECMO), endomyocardial biopsy (EMB) has been recently shown to be feasible and a helpful method to clarify differential diagnoses, including acute myocarditis. This study aimed to evaluate the feasibility and safety of EMB in patients with a left ventricular (LV) implanted Impella® device.

Methods And Results: This retrospective, single-center study involves 22 cardiogenic shock patients [SCAI shock stage: C (91%)] requiring mechanical circulatory support (MCS) either by Impella® axial pumps [20 patients (91%)] alone or in combination with VA-ECMO [2 patients (9%)] between December 2017 and January 2022.

Article Synopsis
  • The Eurotransplant Senior Program focuses on allocating kidneys to older transplant patients, and this study analyzes how AI-driven CT body composition can predict patient and transplant survival.
  • The researchers studied 42 kidney transplant recipients, using various body composition metrics and conducting Cox regression analyses to assess survival impacts at different time intervals.
  • Findings indicate that factors like reduced psoas muscle and skeletal muscle indices significantly influence 1-year kidney transplant survival, while obesity also affects outcomes in later years, suggesting that body composition assessments could enhance survival predictions in transplant patients.

Aims: Rupture of the fibrous cap (RFC) represents the main pathophysiological mechanism causing acute coronary syndromes (ACS). Destabilization due to plaque biomechanics is considered to be importantly involved, exact mechanisms triggering plaque ruptures are, however, unknown. This study aims at characterizing the relation between plaque components and rupture points at ACS-causing culprit lesions in a large cohort of ACS-patients assessed by high-resolution intracoronary imaging.

Manifest heart failure impairs all dimensions of health-related quality of life (HRQOL). However, the role of HRQOL in patients with risk factors for the development of heart failure with preserved ejection fraction (HFpEF) is only poorly understood. In this post-hoc analysis of the DIAST-CHF observational study, we tested the hypothesis whether a lower HRQOL at baseline is prognostically associated with an increase in cardiovascular events during follow-up in elderly patients with a cardiovascular risk profile.

The pathophysiology of heart failure with preserved ejection fraction (HFpEF) is poorly understood and therapeutic strategies are lacking. This study aimed to identify plasma proteins with pathophysiological relevance in HFpEF and with respect to spironolactone-induced effects. We assessed 92 biomarkers in plasma samples from 386 HFpEF patients-belonging to the Aldo-DHF trial-before (baseline, BL) and after one-year treatment (follow up, FU) with spironolactone (verum) or a placebo.

Lipids represent a valuable target for metabolomic studies since altered lipid metabolism is known to drive the pathological changes in cardiovascular disease (CVD). Metabolomic technologies give us the ability to measure thousands of metabolites providing us with a metabolic fingerprint of individual patients. Metabolomic studies in humans have supported previous findings into the pathomechanisms of CVD, namely atherosclerosis, apoptosis, inflammation, oxidative stress, and insulin resistance.

The cardiac lipid panel (CLP) is a novel panel of metabolomic biomarkers that has previously shown to improve the diagnostic and prognostic value for CHF patients. Several prognostic scores have been developed for cardiovascular disease risk, but their use is limited to specific populations and precision is still inadequate. We compared a risk score using the CLP plus NT-proBNP to four commonly used risk scores: The Seattle Heart Failure Model (SHFM), Framingham risk score (FRS), Barcelona bio-HF (BCN Bio-HF) and Meta-Analysis Global Group in Chronic Heart Failure (MAGGIC) score.
