Objective: To study the survival and patient outcome in a population of UK patients supported by an implantable left ventricular assist device (LVAD) as a bridge to heart transplantation.
Methods: Data on all adult patients (n=342) who received a HeartMate II or HVAD as a first long-term LVAD between January 2007 and 31 December 2013 were extracted from the UK Ventricular Assist Device (VAD) Database in November 2015. Outcomes analysed include survival on a LVAD, time to urgent listing, heart transplantation and complications including those needing a pump exchange.
Results: 112 patients were supported with the Thoratec HeartMate II and 230 were supported with the HeartWare HVAD. Median duration of support was 534 days. During the study period, 81 patients required moving to the UK urgent waiting list for heart transplantation. Of the 342 patients, 85 (24.8%) received a heart transplant, this included 63 on the urgent list. Thirty-day survival was 88.9%, while overall patient survival at 3 years from LVAD implant was 49.6%. 156 patients (46%) died during LVAD support; the most common cause of death on a VAD was a cerebrovascular accident. There was no significant difference between the two devices used in any outcome.
Conclusions: In a population of patients with advanced heart failure, who have a very poor prognosis, support with an implantable LVAD allowed a quarter to receive a heart transplant in a 3-year period. Overall survival of the cohort was about 50%. With improvement in technology and in post-LVAD management, it is likely that outcomes will improve further.

Development and Validation of a Neurosurgical Phantom for Simulating External Ventricular Drain Placement.

This study aimed to develop and validate a cost-effective, customizable patient-specific phantom for simulating external ventricular drain placement, combining image segmentation, 3-D printing and molding techniques. Two variations of the phantom were created based on patient MRI data, integrating a realistic skin layer with anatomical landmarks, a 3-D printed skull, an agarose polysaccharide gel brain, and a ventricular cavity. To validate the phantom, 15 neurosurgeons, residents, and physician assistants performed 30 EVD placements.

Background: Knowledge of the chemical composition of amyloid plaques and tau tangles at the earlier stages of Alzheimer's disease (AD) pathology is sparse. This is due to limited access to human brain during life and at the earlier stages of AD pathophysiology and technical limitations in quantifying amyloid and tau species at a subcellular level. Understanding the chemical composition of plaques and tangles, how rapidly they grow and what factors drive growth is important for developing and refining therapeutics.

Background: Left ventricular assist devices (LVADs) are utilized as a therapeutic option for patients with end-stage heart failure. While LVAD implantation can enhance survival rates and quality of life, the procedure has its risks, and postoperative complications are common. This review aims to investigate whether there is an association between living in a rural area and the incidence of postoperative complications or hospital readmissions following LVAD implantation, compared to urban LVAD recipients.

Cardiogenic shock (CS) in acute myocardial infarction (AMI) is a life-threatening syndrome characterized by systemic hypoperfusion that can quickly progress to multiorgan failure and death. Various devices and configurations of mechanical circulatory support (MCS) exist to support patients, each with unique pathophysiological characteristics. The Intra-aortic balloon pump can improve coronary perfusion, decrease afterload, and indirectly augment cardiac output.

- Patients awaiting heart transplants often require colonoscopies due to bleeding or screening needs, but there's limited research on the safety of these procedures for individuals on inotropic medications or mechanical circulatory support.
- A study was conducted from 2015 to 2021 with 92 heart failure patients undergoing colonoscopy while on advanced heart failure therapies, such as inotropes or mechanical devices.
- Results indicated that the most common reason for colonoscopy was cancer screening, with significant findings including 8% of screening procedures revealing advanced adenomas and 17% of bleeding-related colonoscopies identifying sources needing intervention, but no major complications related to anesthesia were reported.
