Chronic Rejection and Atherosclerosis in Post-Transplant Cardiovascular Mortality: Two Sides of the Same Coin
Cardiovascular disease (CVD) as defined by the American Heart Association includes ischaemic heart disease, stroke, heart failure and thromboembolism [1]. Solid organ transplantation is associated with an increased risk of CVD morbidity and mortality [2], a relationship which was first observed in the context of kidney transplantation by Foley in 1998 [3]. This manifests clinically as an increased rate of major adverse cardiovascular events (MACE), defined as the composite of cardiac death, non-fatal myocardial infarction, non-fatal stroke, unstable angina and heart failure [4,5].

Peripheral microvascular dysfunction is associated with plaque progression and adverse long ‐term outcomes in heart transplant patients
ConclusionsPeripheral endothelial dysfunction is associated with increased plaque progression and adverse long-term cardiovascular outcomes in transplant patients. PED assessment might be a useful clinical tool for risk stratification after heart transplantation.

079 Assessing Arterial Pulsatility in Patients With Continuous Flow Left Ventricular Assist Device Support
An increasing number of end-stage heart failure patients are supported by continuous-flow Left Ventricular Assist Devices (cfLVADs) as a bridge to heart transplantation. In these patients, accurate assessment of arterial pulsatility remains a challenge because of diminished pulse pressure, which itself can be associated with adverse events such as gastrointestinal bleeding and stroke. Our study investigates the value of simultaneous arterial pressure and arterial flow velocity assessment in cfLVAD patients.

Risk assessment in PAH using quantitative CMR tricuspid regurgitation: relation to heart catheterization
ConclusionsA clear trend towards worse outcome with larger TRV or TR% was shown; however, the number of events was insufficient for significant outcome differences. Prognostic value of quantitative TR should be investigated in a larger multicentre cohort. Effective RV ejection fraction may be considered an improved measure of RV function in PAH.

1 Ventricular assist devices: developments in asia and global outlook for the next 10 years
The advent of left ventricular assist systems to support patients with advanced-stage heart failure has been a 50 year odyssey, now available broadly to such patients.1 Engineering advances have ushered in an era of small, durable devices that can be fully implanted within the chest. Yet, haemocompatibility related adverse events, which emanate from the interaction between the device and the patient they support are manifest principally in increased stroke rates, de novo device thrombosis requiring replacement and in gastrointestinal bleeding (a peculiar adverse event resulting from the unnatural physiology of continuous f...

Invasive Hemodynamics and Rejection Rates in Patients With Cardiac Sarcoidosis After Heart Transplantation
ConclusionsPatients with CS have similar post-transplant hemodynamics as patients without CS, without evidence of right ventricular dysfunction or pulmonary hypertension. Neither significant rejection nor recurrence of sarcoid in the allograft was observed in this cohort of patients with CS. Survival is similar between patients with CS and those without CS. Heart transplant is a viable strategy in selected patients with CS with excellent outcomes.RésuméIntroductionLa transplantation cardiaque orthotopique (TCO) est de plus en plus utilisée lors d’insuffisance cardiaque terminale liée à une sarcoïdose cardiaque (SC)...
