干预/治疗 |
---|---|
实验性的:Imaging guided LV lead placement
|
LV lead placement guided by cardiac imaging using echocardiography, single-photon emission computed tomography, and CT to target a cardiac vein at the site of latest mechanical activation without scar tissue. Visualization of cardiac venous anatomy is performed using cardiac CT if not contraindicated by depressed renal function (estimated glomerular filtration rate <30 ml/min) or allergy to contrast media. In that case, a coronary venogram is used. |
无干预:Empiric LV lead placement
LV lead placement using standard clinical routine.
