Efficacy of Prophylactic Intra‐Aortic Balloon Pump Therapy in Chronic Heart Failure Patients Undergoing Cardiac Surgery
This study investigated the efficacy of prophylactic intraoperative intra‐aortic balloon pump (IABP) usage in chronic heart failure patients with severely reduced left ventricular function undergoing elective cardiac surgery. Between January 2008 and December 2012, 107 patients with severely reduced left ventricular ejection fraction (LVEF <35%) received prophylactic intraoperative IABP implantation during open‐heart surgery. Surgical procedures performed were isolated coronary artery bypass grafting (CABG) in 35 patients (32.7%), aortic valve replacement in 12 (11.2%), mitral valve repair or replacement in 15 (14.0...

Association between cell-derived microparticles and adverse events in patients with nonpulsatile left ventricular assist devices
Background: Continuous-flow left ventricular assist devices (LVADs) expose blood cells to high shear stress, potentially resulting in the production of microparticles that express phosphatidylserine (PS+) and promote coagulation and inflammation. In this prospective study, we attempted to determine whether PS+ microparticle levels correlate with clinical outcomes in LVAD-supported patients.Methods: We enrolled 20 patients undergoing implantation of the HeartMate II LVAD (Thoratec Corp, Pleasanton, CA) and 10 healthy controls who provided reference values for the microparticle assays. Plasma was collected before LVAD implan...

Utilization of Bioreactance Technique as Indicator for Preload Responsiveness During Living Donor Liver Donation
Conclusions: Our study has shown that SVV measured from the bioreactance technique is a poor indicator for monitoring preload responsiveness during LDLD.

Extracorporeal Membrane Oxygenation: Experience In Acute Graft Failure After Heart Transplantation
ConclusionTemporary ECMO support for postoperative output failure is an acceptable option as a last resort for otherwise doomed patients with fatal graft failure after HTx. The small fraction of patients surviving, appear to have a decent long‐term prognosis.This article is protected by copyright. All rights reserved.

The Policy of Placing Older Donors into Older Recipients: Is it Worth the Risk?
ConclusionsUse of older donors (50yrs) in older recipients (60yrs) results in lower 5‐yr survival and freedom from CAV. Caution is required in these cases. Larger studies are warranted to confirm findings.This article is protected by copyright. All rights reserved.

Post-approval study of a highly pulsed, low-shear-rate, continuous-flow, left ventricular assist device, EVAHEART: A Japanese multicenter study using J-MACS
Conclusions: The EVAHEART device provides safe, reliable and long-term circulatory support with improved survival in commercial settings of BTT in Japan, where the transplant waiting period is much longer. Incidences of GI bleeding, hemolysis, right ventricular failure, device thrombosis and mechanical failure were extremely rare in patients on EVAHEART devices.

Effects of Antegrade and Retrograde Machine Perfusion Preservation on Cardiac Function After Transplantation in Canines
Abstract: Introduction: Most studies investigating machine perfusion preservation for heart transplantation perfuse through the aortic root (antegrade), but the coronary sinus (retrograde) is a potential option. We hypothesized that retrograde machine perfusion provides better functional protection than static storage, while avoiding the potential irregular perfusion seen when aortic insufficiency occurs with antegrade perfusion.Materials and Methods: Eighteen canine donor hearts were arrested, procured, and stored in modified Celsior solution for 4 hours by using either static storage at 0°C to 4°C (n = 6) or machine p...

High early cardiovascular mortality following liver transplantation
Abstract Cardiovascular disease (CVD) contributes to excess long‐term mortality after liver transplantation (LT), however little is known about early post‐operative CVD mortality in the current era. In addition, there is no model to predict early post‐operative CVD mortality across centers. We analyzed adult recipients of primary LT in the Organ Procurement and Transplantation Network (OPTN) database between February 2002 and December 2012 to assess prevalence and predictors of early (30‐day) CVD mortality, defined as death from arrhythmia, heart failure, myocardial infarction, cardiac arrest, thromboembolism, and/...

Pump size of Berlin Heart EXCOR pediatric device influences clinical outcome in children
Conclusions: The broad range of body sizes in children from newborns to adolescents requires a wide choice of appropriately sized devices. Large pump size in relation to BSA is an independent risk factor for occurrence of thromboembolic events.

Inadequate Venous Return As A Primary Cause For Fontan Circulatory Limitation
The Fontan procedure is an approach to single ventricle palliation involving connection of systemic veins to the pulmonary artery(PA) without a functional sub-pulmonary pumping chamber. This is associated with chronically elevated systemic venous pressure and limited stroke volume augmentation. The latter is usually attributed to either inability to increase transpulmonary flow related to abnormal pulmonary vascular response in the absence of a sub-pulmonary ventricle or to low ventricular compliance.

The aim of this study was to evaluate the prevalence of early pump power elevation events in patients with the HeartMate II (HMII) and its impact on subsequent development of stroke and pump thrombosis.

Early outcomes of extra-thoracic debranching thoracic endovascular aortic repair for distal aortic arch disease
In conclusion, the early outcomes of extra-thoracic debranching TEVAR in high-risk patients with distal aortic arch disease were satisfactory and encouraging, compared with conventional arch replacement. Extra-thoracic debranching TEVAR has the advantage of less invasiveness and no possibility of sternal infection.
