Curved Bistable Origami‐Inspired Flexible Transcatheter Mitral Valve Clamping

open access: yesAdvanced Science, EarlyView.
A lightweight bistable curved origami dilator combines reversible deformation and high stability, offering a promising solution for minimally invasive mitral valve repair. Abstract Curved origami exhibits remarkable potential for minimally invasive medical applications owing to its unique geometric programmability and mechanical tunability. Building on

Pre-revascularization coronary wedge pressure as marker of adverse long-term left ventricular remodelling in patients with acute ST-segment elevation myocardial infarction

open access: yesScientific Reports, 2018
The aim of this study was to investigate the relationship between coronary wedge pressure (CWP), measured as a marker of pre-procedural microvascular obstruction, and left ventricular remodelling in high-risk ST-segment elevation myocardial infarction ...

Levosimendan for patients with severely reduced left ventricular systolic function and/or low cardiac output syndrome undergoing cardiac surgery. a systematic review and meta-analysis [PDF]

open access: yes, 2017
Background: Previous studies have shown beneficial effects of levosimendan in high-risk patients undergoing cardiac surgery. Two large randomized controlled trials (RCTs), however, showed no advantages of levosimendan.

Microgel‐Based Hierarchical Porous Hydrogel Patch with Adhesion and Resilience for Myocardial Infarction

open access: yesAdvanced Science, EarlyView.
This study develops a hierarchically porous hydrogel patch strategy (HPMP), based on gas‐shearing microfluidics and an aqueous two‐phase system to fabricate porous microgels as microgel‐based bioinks. The porous microgels with controllable porous structure exhibit excellent cellular behavior.

Heart rate changes during the Valsalva maneuver in patients with isolated aortic insufficiency

open access: yesBrazilian Journal of Medical and Biological Research, 1997
To determine the possible relationship between left ventricular dilatation and heart rate changes provoked by the Valsalva maneuver (Valsalva ratio), we studied 9 patients with isolated chronic aortic insufficiency. Left ventricular systolic function was

Cardiogenic Shock Induced by Coronary Steal Syndrome Through a Neovessel of Mediastinal Neuroendocrine Tumor

open access: yesJACC: Case Reports, 2019
A woman was admitted for cardiogenic shock with a left ventricular ejection fraction of 15%. Coronary angiography showed a neovessel coursing superiorly toward a mediastinal mass.

Left ventricular ejection fraction: clinical, pathophysiological, and technical limitations

open access: yesFrontiers in Cardiovascular Medicine
Risk stratification of cardiovascular death and treatment strategies in patients with heart failure (HF), the optimal timing for valve replacement, and the selection of patients for implantable cardioverter defibrillators are based on an echocardiographic calculation of left ventricular ejection fraction (LVEF) in most guidelines.
