Most post-infarct ventricular tachycardias (VT) are sustained by a reentrant mechanism. The 'protected isthmus' of the reentrant circuit is critical for the maintenance of VTs and the target for catheter ablation. Various techniques, based upon conventional electrophysiology and/or detailed 3D reconstruction of the VT circuit are used to unmask this ...

Prognostic factors are usually evaluated by their statistical significance rather than by their clinical utility. Risk reclassification measures the extent to which a novel marker adds useful information to a prognostic model. The extent to which estimated glomerular filtration rate (eGFR) adds information about prognosis among patients with coronary heart ...
