Top Advances in Echocardiography Transforming Cardiac Imaging on World Heart Day
In honor of World Heart Day on September 29, we're diving into the world of cardiovascular diagnostics. Echocardiography, one of the most widely used screening and diagnostic modalities in healthcare, has seen a resurgence thanks to advances and groundbreaking innovations within the last few years. Join us as we explore the top trends shaping these diagnostic methods. 1. ...

Diagnosing heart failure with preserved ejection fraction (HFpEF)
Heart failure with preserved ejection fraction (HFpEF) has recently been recognized as the single greatest unmet need in cardiovascular medicine, overtaking heart failure with reduced ejection fraction (HFrEF) and becoming the most common form of heart failure, with a prevalence that is increasing by 1% annually.[1] Despite this, there remains no gold standard in diagnosing HFpEF. Diagnosing ...

What is heart failure with preserved ejection fraction (HFpEF)?
Overview What is HFpEF? Heart failure with preserved ejection fraction (HFpEF) is a clinical syndrome in which patients have signs and symptoms of HF as the result of high left ventricular (LV) filling pressure, despite normal or near-normal LV ejection fraction (EF). Most patients with HFpEF also display normal LV volumes and an abnormal diastolic filling pattern (i.e, diastolic ...

The Use of High-Frequency Jet Ventilation in the Management of a Pre-term Infant with Pulmonary Stenosis and Respiratory Distress Syndrome. – A Case Report
The combination of congenital heart disease (CHD) and respiratory distress syndrome (RDS) can present a difficult scenario to manage with conventional mechanical ventilation (CMV). Our patient presented with poor right ventricular (RV) function, and refractory respiratory failure on CMV. High-frequency jet ventilation (HFJV) was used in order to improve ventilation at a similar or lower mean ...

Accuracy of Pulse Oximeters Intended for Hypoxemic Pediatric Patients - Case study
OBJECTIVES: Prior studies have shown inaccuracies in pulse oximetry readings at saturations less than 85%; however, no large studies have evaluated new sensors marketed for these low saturations. This study's purpose was to evaluate two sensors with claims of improved accuracy in children with saturations less than 85%. DESIGN: Prospective observational study. SETTING: Single institution; ...

Understanding Pediatric Cardiomyopathy: Causes, Symptoms and Treatment Options
Up to 5,000 American infants and children are diagnosed with pediatric cardiomyopathy each year. Learn more about this rare but potentially serious condition. Cardiomyopathy, which is a general term for diseases of the heart muscle, is relatively rare in children, affecting only about 12 out of every 1 million Americans under the age of 18. Among the approximately 1,000 to 5,000 new cases ...

First-in-man demonstration of 18-month spatiotemporal stability of active atrial fibrillation source detected by Electrographic Flow mapping in persistent atrial fibrillation
Keywords: atrial fibrillation, catheter ablation, mapping, atrial fibrillation, source, electrographic flow Introduction: Advanced mapping methods for atrial fibrillation (AF) have previously suffered from poor spatiotemporal stability. Electrographic flow (EGF) mapping is a novel technique using computer vision and optical flow smoothing algorithms to avoid this issue. The aim of this ...

Functional Electrographic Flow Patterns in Patients with Persistent Atrial Fibrillation Predict Outcome of Catheter Ablation
Aims: Electrographic flow (EGF) mapping is a method to detect action potential sources within the atria. In a double-blinded retrospective study we evaluated whether sources detected by EGF are related to procedural outcome. Methods: EGF maps were retrospectively generated using the Ablamap® software from unipolar data recorded with a 64-pole basket catheter from patients who previously ...

Velocity characteristics of atrial fibrillation sources determined by electrographic flow mapping before and after catheter ablation
Background: Electrographic-Flow-(EGF)-Mapping is a novel method to identify Atrial Fibrillation (AF) drivers. Sources of excitation during AF can be characterized and monitored. Objective: The aim of this study was to evaluate the correlation between velocity of EGF around a respective AF source and its spatial variability (SV) and stability (SST). Methods: 25 patients with AF were included in ...

Ancora Heart sees positive early results with Accucinch in systolic heart failure
Ancora Heart Inc., a Santa Clara, Calif.-based company looking to help those with heart failure, is heralding results from an interim analysis of patients treated in a U.S. early feasibility study evaluating the safety of the investigational Accucinch ventricular repair system. The multicenter, nonrandomized, prospective study is assessing the system in patients with symptomatic heart failure ...

Identification of active atrial fibrillation sources and their discrimination from passive rotors using electrographical flow mapping
Barbara Bellmann 1, Tina Lin 2, Peter Ruppersberg 3, Marit Zettwitz 1, Selma Guttmann 1, Verena Tscholl 1, Patrick Nagel 1, Mattias Roser 1, Ulf Landmesser 2, Andreas Rillig 4 Background: The optimal ablation approach for the treatment of persistent atrial fibrillation (AF) is still under debate; however, the identification and elimination of AF sources is thought to play a key role. Currently ...

A New Device to Markedly Reduce Personnel Radiation Exposure in the Cardiac Cath Lab
Background Radiation exposure that physicians and hospital staff receive while treating patients has recently been associated with a marked increase in cancer, cataracts, and skin lesions. Staff in cardiac catheterization and interventional radiology laboratories have the highest radiation exposure of any profession, despite the use of standard x-ray ...
