Objective Coronary angiography (CA) remains the standard for preoperative planning for surgical revascularization. However, besides anatomical imaging, current guidelines recommend additional functional imaging before a therapy decision is made. We assess the impact of functional imaging on the strategy of coronary artery bypass grafting (CABG) with particular regards on postoperative patency ...

Electrocardiography parameters can predict cardiac events in ischemia. QT-interval parameters are potentially proposed as available non-invasive markers for assessing the ventricular homogeneity and electrical instability. Prolonged QT-interval (QTI) and QT dispersion (QTd) are predictors of poor prognosis and fatal arrhythmias. The improvement of cardiac perfusion may decrease QTI via percutaneous ...

Functional mitral regurgitation (FMR) occurs when normal or nearly normal mitral leaflets are prevented from proper coaptation by underlying left ventricular (LV) dysfunction, mitral annular dilation, or both. FMR is associated with an adverse prognosis in nonischemic or ischemic LV dysfunction. Multiple studies have confirmed that even mild FMR portends ...

Generating myocyte grafts that bridge across infarcts could maximize their functional impact and best utilize small numbers of stem cells. To date, however, graft survival within acute infarcts has not been feasible. To enhance intrainfarct graft viability, human embryonic stem cell-derived cardiomyocytes (hESC-CMs) were pretreated before implantation with cobalt protoporphyrin ...

There is little evidence on the optimal mode of clopidogrel discontinuation. Epidemiological studies observed clustering of thrombotic events after cessation of chronic clopidogrel therapy. The underlying mechanism has been ascribed to transient platelet hyper-reactivity. Gradual tapering of clopidogrel may have the potential to attenuate this phenomenon. The objective of the ...
