The application of laser welding on Left Ventricular Assist Device (LVAD)

2011 Symposium on Photonics and Optoelectronics (SOPO), 2011
A successful and useful treatment for end-stage heart failure is Left ventricular assist device (LVAD). An important part - a hydrodynamically suspended impeller exposed to corrosive conditions, required to sealed hermetically into micro packages.

Hyperpolypharmacy is a predictor of mortality after left ventricular assist device (LVAD) implantation. [PDF]

Am Heart J Plus, 2022
The prevalence of (hyper)polypharmacy in patients on left ventricular assist device (LVAD) support and its effect on clinical outcomeis unknown. Therefore, we aimed to determine the prevalence of (hyper)polypharmacy in LVAD patients and evaluate its association with mortality and complications.210 patients aged ≥40 years who received a primary LVAD ...

Mycobacterium abscessus Infection in Left Ventricular Assist Device (LVAD): A Case Series. [PDF]

Cureus, 2021
The limited availability of donor organs worldwide, has provoked a surge in the need for implantable left ventricular assist devices (LVADs) mainly as a bridge to heart transplantation or destination therapy. The rate of complications from LVAD use is also increasing, impacting morbidity, mortality, and costs.

Clinical Evaluation Gf Right Ventricular Function in Patients with Left Ventricular Assist Device (Lvad)

The International Journal of Artificial Organs, 1992
Right ventricular function (RVF) during LVAD support can be a threat for patient survival. Despite extensive research, RVF and its interference with left heart function is unclear.

Hemodynamic and Energetic Assessment of Calves Implanted with a Left Ventricular Assist Device (LVAD)

The International Journal of Artificial Organs, 1988
Hemodynamic and ventricular energetic parameters were measured in calves implanted with the air driven Utah Ventricular Assist Device (UVAD). Uptake site was varied to determine the effect of control mode and vacuum augmentation of filling.

Sequential cataract surgeries in a patient with a left ventricular assist device (LVAD). [PDF]

BMJ Case Rep, 2018
The population of patients on left ventricular assist devices (LVADs) has increased significantly since the 1990s, and with it, need for non-cardiac elective surgeries. Presence of an LVAD or heart failure, however, can cause physicians to perceive these patients to be at prohibitively high risk for elective surgery.

Impact of an Accessory for Left Ventricular Assist Devices on Device Flow and Pressure Head In Vitro

Bioengineering, 2023
A novel accessory directing the blood from the outflow of a left ventricular assist device (LVAD) back through the left ventricular apex and across the aortic valve allows LVAD implantation via the left ventricular apex solely but may affect the LVAD ...

Hypertension and Stroke in Patients with Left Ventricular Assist Devices (LVADs) [PDF]

Current Hypertension Reports, 2016
Stroke is one of the most dreaded complications of left ventricular assist device therapy in patients with end-stage congestive heart failure. There is strong evidence linking anticoagulation and infection with ischemic and hemorrhagic strokes, though recent data has emerged regarding the importance of elevated blood pressure. In the recently completed

Is it Safe for Patients with Left Ventricular Assist Devices to Undergo Non-Cardiac Surgery?

Medicina, 2020
Background and Objectives: Since the first use of ventricular assist devices (VADs) as bridge to recovery and bridge to cardiac transplantation in the early 1990s, significant technological advances have transformed VAD implantation into a routine ...
