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 ...

Vorticity‐Facilitated Platelet Aggregation: a High Expansion‐Ratio Stenotic Microfluidic Platform Unravels the Role of Complex Flow Dynamics in Arterial Thrombosis

Advanced Healthcare Materials, EarlyView.
This study reveals how vorticity—a swirling flow pattern—enhances platelet aggregation and thrombus formation in high‐shear conditions. Using a custom microfluidic model, it is shows that vorticity promotes vWF–GPIbα interactions and calcium signaling, providing new insights into thrombosis mechanobiology and informing safer blood‐contacting medical ...

Tapered Pillar Design for High‐Precision Force Readout in Miniaturized Engineered Heart Tissues From Human Pluripotent Stem Cells

Advanced Healthcare Materials, EarlyView.
Engineered heart tissues (EHTs) are a valuable approach in capturing human cardiac physiology and drug responses in vitro. Here, a novel tapered pillar design is developed in an EHT platform to confine tissues in a predefined position‐ at the middle of the pillar height.

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.

Catheter Ablation as a Treatment for Vasovagal Syncope: Long‐Term Outcome of Endocardial Autonomic Modification of the Left Atrium

Journal of the American Heart Association : Cardiovascular and Cerebrovascular Disease, 2016
Background Autonomic modification through catheter ablation of ganglionated plexi (GPs) in the left atrium has been reported previously as a treatment for vasovagal syncope. This study aimed to observe the long‐term outcome in a larger cohort.
