Outcomes of ventricular assist device implantation in children and young adults: the Melbourne experience
ConclusionsChildren requiring pre‐transplant VAD support have a higher mortality and morbidity compared with young adults. Survival after heart transplantation those supported with VADs was similar to patients of similar age who did not require pre‐transplant support.

Short and long term outcomes of 200 patients supported by continuous-flow left ventricular assist devices.
CONCLUSION: Short and long term survival for patients on LVAD support are excellent, although outcomes still remain inferior compared to heart transplantation. The incidence of driveline infections, pump thrombosis and pump exchange have declined significantly in recent years.

Cerebral air embolism during CT-guided lung biopsy
A patient with cirrhosis and hepatocellular carcinoma, on the waiting list for liver transplantation, presented with lung nodule during initial evaluation. A CT-guided core needle lung biopsy under general anaesthesia was performed. Pneumothorax (figure 1) and a large amount of gas within the left ventricle (figure 2) were identified during the procedure. Neurological focal signs (drowsiness, conjugate eye deviation and right hemiparesis) were observed in the anaesthesia-recovery period. A brain CT scan was immediately obtained, showing cerebral air embolism (figure 3). Initial resuscitation and hyperbaric oxygen therapy w...

Platelet-derived VWF is not essential for normal thrombosis and hemostasis but fosters ischemic stroke injury in mice
Von Willebrand factor (VWF) is a key hemostatic protein synthesized in both endothelial cells and megakaryocytes. Megakaryocyte-derived VWF is stored in α-granules of platelets and is enriched in hyperactive "ultra-large" VWF multimers. To elucidate the specific contribution of platelet VWF in hemostasis and thrombosis, we performed crossed bone marrow transplantations between C57BL/6J and Vwf–/– mice to generate chimeric mice. Chimeric mice specifically lacking platelet VWF showed normal tail bleeding and carotid artery thrombosis, similar to wild-type mice. Chimeric mice with VWF present only in platele...

HeartWare completes enrollment in Endurance2 HVAD trial
HeartWare International (NSDQ:HTWR) said today it completed enrollment of its Endurance 2 destination therapy trial of its HeartWare ventricular assist system.
The trial seeks to examine the rate of stroke in patients treated with HeartWare’s HVAD device as well as optimal blood pressure management, the company said.
Data from the 465-patient supplemental cohort trial will be used to support pre-market approval for the HeartWare HVAD as a destination therapy system intended for long term use, according to the Framingham, Mass.-based company.
The device is currently FDA approved for bridge-to-transplant applications....

FDA warns on potential LVAD issues
The FDA published a safety communication today warning about issues with implantable left ventricular assist devices.
The federal watchdog referenced specific issues with both approved implantable LVADs: Thoratec’s HeartMate II and HeartWare’s HVAD system.
Adverse events referenced included increased rate of pump thrombosis with the HeartMate II and a high rate of stroke with HeartWare’s HVAD, as well as bleeding complications associated with both devices.
The FDA said they have received reports and information from a “variety of sources indicating an increase in the rate of pump thrombosis events i...

The Subclavian Intraaortic Balloon Pump: A Compelling Bridge Device for Advanced Heart Failure
Conclusions The SC-IABP provided excellent hemodynamic support with minimal morbidity and mortality, allowed for extensive rehabilitation, and permitted more than 90% of patients to receive their intended therapy. Therefore, SC-IABP is a compelling bridge device for patients with advanced congestive heart failure.

Readmissions After Continuous Flow Left Ventricular Assist Device Implantation: Differences Observed Between Two Contemporary Device Types
Readmissions after continuous flow left ventricular assist devices implantation are common. We compared the frequency and etiology of readmissions between two continuous flow left ventricular assist devices 6 months after implant. We retrospectively assessed readmissions in 81 patients who received a bridge to transplant HeartMate-II (HM-II) n = 35, 43% or HeartWare (HW) n = 46, 57%, from 2009 to 2014. Readmissions were divided into cardiac, infection, gastrointestinal bleeding, stroke, pump thrombosis, and miscellaneous profiles. Age, gender, creatinine, INTERMACS profiles were comparable between groups (p> 0.05). Sixty-o...

Impact of Renal Impairment on Cardiovascular Disease Mortality After Liver Transplantation for Nonalcoholic Steatohepatitis Cirrhosis
ConclusionNASH recipients have an increased risk of CVD mortality after liver transplantation explained by a high prevalence of co‐morbid cardiometabolic risk factors that in aggregate identify those at highest risk of post‐transplant CVD mortality.This article is protected by copyright.

Acute ischemic stroke due to Left Ventricular Noncompaction Syndrome from a novel mutation of the Lamin A/C gene (P2.254)
Conclusion: LVNC is a risk factor for cardioembolic ischemic stroke particularly in young patients that is not well known. Patients with suspected LVNC by echocardiography should undergo cardiac MRI for confirmation and genetic testing in particular for mutations in the LMNA gene. The prognosis of those with LVNC syndrome is poor; most worsen over time and need ultimately transplantation. Close follow-up is required.Disclosure: Dr. Vongveeranonchai has nothing to disclose.

Percutaneous Driveline Infection Does Not Increase Subsequent Risk of Stroke and Pump Thrombus During Support With a Left Ventricular Assist Device
Percutaneous driveline infections (DLI) pose significant risk in patients supported with a left ventricular assist device (LVAD). While INTERMACS data suggests increased incidence of thromboembolic complications in close proximity following DLI, no study has specifically examined this association in a time-dependent manner and analyzed risk of subsequent events. We reviewed the Mechanical Circulatory Support (MCS) Research Network registry.

Impact of a Modified Anti-Thrombotic Protocol on the Risk of Stroke and Thromboembolism in Children Supported With the Berlin Heart Excor Pediatric Ventricular Assist Device
Stroke is the most recognized complication associated with the Berlin Heart EXCOR® Pediatric ventricular assist device (VAD). We sought to determine whether a modified anti-thrombotic protocol, involving more intense platelet inhibition and less reliance on Thromboelastrography/ Platelet Mapping™ (TEG/PM), is associated with a lower incidence of stroke.

Driveline Infection Is Not Associated With Increased Risk of Thrombotic Events in CF-LVAD Patients
It has been debated whether anti-thrombotic therapy should be adjusted in the setting of driveline infection (DLI) as infection may lead to a pro-inflammatory state associated with platelet activation and increased risk of thrombotic complications. The aim of this study was to examine the relationship of DLI and thrombotic complications, notably stroke and device thrombosis (DT), in patients with continuous-flow LVADs.
