Atrial Fibrillation Management in Heart Failure: Interrupting the Vicious Cycle
AbstractPurpose of reviewIn this review article, we aim to describe the pathophysiology of concomitant atrial fibrillation and both left and right heart failure, as well as pronounce the prognosis of having these two conditions simultaneously. This review also summarizes the current management of atrial fibrillation including stroke and thromboembolism prevention in the presence of systolic and diastolic heart failure.Recent findingsWhile rhythm control strategy is not superior to rate control strategy in atrial fibrillation patients without heart failure, catheter ablation for atrial fibrillation has shown to improve outc...

Left Ventricular Assist Devices (LVADS): History, Clinical Application and Complications.
Authors: Eisen HJ Abstract Congestive heart failure is a major cause of morbidity and mortality as well as a major health care cost in the developed world. Despite the introduction of highly effective heart failure medical therapies and simple devices such as cardiac resynchronization therapy that reduce mortality, improve cardiac function and quality of life, there remains a large number of patients who do not respond to these therapies or whose heart failure progresses despite optimal therapy. For these patients, cardiac transplantation is an option but is limited by donor availability as well as co-morbidities w...

Age-Dependence of Flow Homeostasis in the Left Ventricle
Conclusions: In average, blood spends 1 to 3 beats inside the LV with very low shear stress rates. The apical region is the most prone to blood stasis, particularly in mid-aged adults. The washout of blood in the normal LV is age-dependent due to physiological changes in the degree of apical penetration of the filling waves. Introduction Cardioembolic stroke is a major source of mortality and disability worldwide and blood stasis one of its major determinants (Adams et al., 1986). Left ventricular (LV) function has evolved to maximize mechanical efficiency and ensure organ perfusion at a low cost of energy and fill...

Recent advances in heart failure
Purpose of review Acute heart failure continues to be a challenge as there is limited benefit of numerous agents that have been tested. Cardiac resynchronization therapy remains standard of care, yet timing and need for implantable cardiac defibrillator has been brought into question with the recent randomized trials. Several recent advances have been made towards management of heart failure both in drug and device therapy. The purpose of this review is to provide an update on the most important recent studies on heart failure with reduced ejection fraction (HFrEF) and heart failure with preserved ejection fraction (HFpE...

HRS 2016 roundup: Leadless pacers at the fore
Medtronic (NYSE:MDT) and St. Jude Medical (NYSE:STJ), aiming to distinguish their respective leadless pacemaker offerings, presented new data last week in San Francisco at the Heart Rhythm Society’s annual meeting. St. Jude said a subset of data from the Leadless II trial showed that its Nanostim device was was successfully retrieved in 14 patients up to 3.2 years after implantation, with no serious adverse events. “We’ve now shown that for patients requiring device upgrades or new leadless pacing options, late retrievability – even up to 3 years – is possible with the Nanostim leadless pacemak...
