22,586 | Keep shocking: Double sequential defibrillation for refractory ventricular fibrillation. | Double sequential defibrillation is proposed as a novel modality of managing refractory ventricular fibrillation (VF). However, existing evidence has not been enough to support this. Here, we report an interesting case of a 54-year-old male who suffered from cardiac arrest with VF rhythm. The patient did not respond to... |
22,587 | Impact of Left Ventricular End-Diastolic Pressure on the Outcomes of Patients Undergoing Percutaneous Coronary Intervention. | Left ventricular end-diastolic pressure (LVEDP) is an important hemodynamic marker of left ventricular performance and affects coronary perfusion. We evaluated the association of LVEDP with patient outcomes after elective or urgent percutaneous coronary intervention (PCI). We included n = 49,600 patients unde... |
22,588 | Cardiac TRPV4 channels. | Transient Receptor Potential Vanilloid 4 (TRPV4) is expressed in numerous cell types within the heart, yet the expression levels, subcellular localization, and functional relevance of TRPV4 in cardiac myocytes is under-appreciated. Recent data indicate a critical role of TRPV4 in both atrial and ventricular myocyte bio... |
22,589 | Pharmacologic Therapy for Heart Failure with Preserved Ejection Fraction. | The management of heart failure with preserved ejection fraction (HFpEF) is rapidly evolving. The pharmacologic treatment of patients with HFpEF includes symptom management with diuretics and optimization of comorbidities, including hypertension, obesity, diabetes mellitus, and atrial fibrillation. Specific therapies, ... |
22,590 | Prognostic Impact of Landiolol in Patients with Acute Heart Failure and Atrial Fibrillation with Rapid Ventricular Rates: A Pilot Observational Study. | Guidelines recommend ventricular rate control to <130 bpm during atrial fibrillation (AF) in patients with acute decompensated heart failure (ADHF) to avoid aggravating deteriorations in cardiac outputs. We aimed to evaluate the prognostic impact of landiolol in patients with ADHF and AF.</AbstractText>This observat... |
22,591 | The characteristics of pre-excitation syndrome concomitant with atrial tachyarrhythmia and the effect of radiofrequency ablation. | Wolff-Parkinson-White (WPW) concomitant with atrial tachyarrhythmia (ATA) has not been systemically characterized.</AbstractText>Detailed electroanatomical mapping of the right atrium (RA) and/or left atrium (LA) was performed using three-dimensional mapping and the accessory pathway (AP) was mapped.</AbstractText>WPW ... |
22,592 | Programmed Ventricular Stimulation as an Additional Primary Prevention Risk Stratification Tool in Arrhythmogenic Right Ventricular Cardiomyopathy: A Multinational Study. | A novel risk calculator based on clinical characteristics and noninvasive tests that predicts the onset of clinical sustained ventricular arrhythmias (VA) in patients with arrhythmogenic right ventricular cardiomyopathy (ARVC) has been proposed and validated by recent studies. It remains unknown whether programmed vent... |
22,593 | The new 2022 ESC Guidelines on Cardio-oncology and their impact on the Acute Cardiovascular Care Society. | In this perspective piece on the recently published ESC Guidelines on Cardio-oncology and the Consensus Statements from the Acute Cardiovascular Care Association, we summarize key learning points regarding the management of acute cardiovascular disease in patients with cancer. This document outlines where other pre-exi... |
22,594 | Long-Term prognosis of radiofrequency catheter ablation for atrial fibrillation with different subtypes of heart failure in the era of ablation index guidance. | The long-term outcomes of ablation index (AI)-guided radiofrequency catheter ablation (RFCA) on atrial fibrillation (AF) and different subtypes of heart failure (HF) remain unknown. The aim of the study was to evaluate the long-term prognosis of AI-guided RFCA procedures in patients with AF and concomitant HF.</Abstrac... |
22,595 | Mitral Annular Plane Systolic Excursion (MAPSE) as a Predictor of Atrial Fibrillation Recurrence in Patients after Pulmonary Vein Isolation. | Catheter ablation (CA) with pulmonary vein isolation (PVI) has become widely used in the past years for the treatment of atrial fibrillation (AF). Mitral annular plane systolic excursion (MAPSE) is the parameter that measures left ventricular longitudinal function, and it appears to be a good early marker of LV dysfunc... |
22,596 | 1-Year Outcomes of Cardioband Tricuspid Valve Reconstruction System Early Feasibility Study. | Tricuspid regurgitation (TR) is prevalent and undertreated, with mortality and morbidity increasing with TR severity. Given poor outcomes with medical therapy and high in-hospital mortality for isolated tricuspid valve surgery, emerging transcatheter repair devices offer a promising alternative.</AbstractText>The Edwar... |
22,597 | Prediction of Death or HF Hospitalization in Patients With Severe FMR: The COAPT Risk Score. | There are limited data on the predictors of death or heart failure hospitalization (HFH) in patients with heart failure (HF) with functional mitral regurgitation (FMR).</AbstractText>The aim of this study was to develop a predictive risk score using the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percuta... |
22,598 | Diagnostic Accuracy of the 2016 Guideline-Based Echocardiographic Algorithm to Estimate Invasively-Measured Left Atrial Pressure by Direct Atrial Cannulation. | Although estimation of left ventricular filling pressure (LVFP) using an integrated echocardiographic algorithm is recommended, the usefulness of this algorithm has not been fully validated.</AbstractText>The purpose of this study was to investigate the reliability of an algorithmic classification system using invasive... |
22,599 | Autonomic nervous system and arrhythmias in structural heart disease. | The autonomic nervous system functions in a fine-tuned manner to dynamically modulate cardiac function during normal physiological state. Autonomic dysregulation in cardiac disease states such as myocardial infarction and heart failure alters this fine balance, which in turn promotes disease progression and arrhythmoge... |
