Change of “Left atrium ejection force” after transcatheter “Atrial septal defect” closure using “AMPLATZER,” in pediatric patients

Research in Cardiovascular Medicine, 2018
Background and Purpose: There has not been any study regarding atrial systolic function in transcatheter atrial septal defect (ASD) closure. The aim of this study was to survey left atrium ejection force in this procedure in the pediatric age group ...

Electromechanical left atrial function in patients with varying degrees of hypertension [PDF]

Praxis Medica, 2014
Atrial arrhythmias are an often and common problem in patients with arterial hypertension. Some recent studies have shown that the electrical pulse delay estimated by echocardiography is prolonged in patients with paroxysmal atrial fibrillation compared ...

Laser‐Induced Graphene‐Assisted Patterning and Transfer of Silver Nanowires for Ultra‐Conformal Breathable Epidermal Electrodes in Long‐Term Electrophysiological Monitoring

Advanced Functional Materials, EarlyView.
This study presents a novel method using laser‐induced graphene (LIG) to enable high‐yield transfer of silver nanowire (AgNW) networks onto ultra‐low modulus, breathable silicone substrates. This approach creates ultra‐conformal epidermal electrodes (≈50 µm) for long‐term, high‐fidelity electrophysiological monitoring, even in challenging conditions ...

Clinical overview on RASopathies

American Journal of Medical Genetics Part C: Seminars in Medical Genetics, Volume 190, Issue 4, Page 414-424, December 2022., 2022
Abstract RASopathies comprise a group of clinically overlapping developmental disorders caused by genetic variations affecting components or modulators of the RAS‐MAPK signaling cascade, which lead to dysregulation of signal flow through this pathway.

Ruptured Sinus of Valsalva Aneurysm into the Left Atrium with Multiple Fistulous Communications: A Rare Cause of Heart Failure [PDF]

, 2015
Ruptured noncoronary sinus of valsalva aneurysm with fistulous connections to multiple cardiac chambers has not been reported previously. We report a 66-year-old man who presented with worsening cough and exertional dyspnea.

Mitral annuloplasty with the interatrial groove-left atrial dome approach in a patient with Marfan syndrome

Journal of Cardiothoracic Surgery, 2022
Background The choice of mitral valve surgical approach has always been a difficult problem in patients with small left atrium. Case presentation We report a case of a patient with Marfan syndrome who underwent the David operation and mitral annuloplasty.

Protein‐Like Polymers Targeting Keap1/Nrf2 as Therapeutics for Myocardial Infarction

Advanced Materials, EarlyView.
We describe a Keap1 targeting protein‐like polymer (PLP) which activates Nrf2, an important cytoprotective transcription factor for relieving myocardial infarction‐induced oxidative stress. This PLP increases cell survival in vitro in multiple relevant cardiac cell types and elicits pro‐reparative responses, improving cardiac function in a preclinical ...

3-D/2-D Registration of Cardiac Structures by 3-D Contrast Agent Distribution Estimation [PDF]

, 2016
For augmented fluoroscopy during cardiac catheter ablation procedures, a preoperatively acquired 3-D model of the left atrium of the patient can be registered to X-ray images. Therefore the 3D-model is matched with the contrast agent based appearance of the left atrium.
