From Rigid to Soft Robotic Approaches for Minimally Invasive Neurosurgery [PDF]

arXiv
Robotic assistance has significantly improved the outcomes of open microsurgery and rigid endoscopic surgery, however is yet to make an impact in flexible endoscopic neurosurgery. Some of the most common intracranial procedures for treatment of hydrocephalus and tumors stand to benefit from increased dexterity and reduced invasiveness offered by ...

Multilevel preconditioner of Polynomial Chaos Method for quantifying uncertainties in a blood pump [PDF]

arXiv, 2017
More than 23 million people are suffered by Heart failure worldwide. Despite the modern transplant operation is well established, the lack of heart donations becomes a big restriction on transplantation frequency. With respect to this matter, ventricular assist devices (VADs) can play an important role in supporting patients during waiting period and ...

Real Time Hemodynamic Monitoring During M‐TEER Using Electrical Cardiometry

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Mitral regurgitation is a common valvular dysfunction causing patient morbidity and mortality. Mitral transcatheter edge‐to‐edge repair (M‐TEER) allows grasping of valvular leaflets and approximation via a small implant, thus reducing mitral regurgitation (MR).

Impact of Elevated Preprocedural Left Ventricular Filling Pressure on Prognosis of Mild Paravalvular Regurgitation Following Transcatheter Aortic Valve Replacement

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background Paravalvular regurgitation (PVR) following transcatheter aortic valve replacement (TAVR) is a complication linked to poor outcomes. The prognostic impact of mild PVR, particularly in patients with elevated preprocedural left ventricular (LV) filling pressure, remains uncertain.

Surgical Outcomes of Centrifugal Continuous-Flow Implantable Left Ventricular Assist Devices: Heartmate 3 versus Heartware Ventricular Assist Device

Journal of Chest Surgery
Background: Left ventricular assist devices (LVADs) are widely employed as a therapeutic option for end-stage heart failure. We evaluated the outcomes associated with centrifugal- flow LVAD implantation, comparing 2 device models: the Heartmate 3 (HM3)
