Ischemic Coronary Disease

Optimal patient selection for cardiac resynchronization therapy is crucial. There are several concerns that allow to better clarify the association between the ischemic etiology of heart failure and the response to cardiac resynchronization therapy. The type of ischemic coronary disease has an impact on the responses to cardiac resynchronization therapy. The prognostic impact of cardiac resynchronization therapy on cardiac death including heart transplantation and durable ventricular assist device implantation is another concern.

Consensus Report

Cardiac resynchronization therapy (CRT) has important role in the contemporary treatment of heart failure, systolic dysfunction and mechanical disynchrony. Classical indications for CRT are severe heart failure (NYHA class III or IV), a broad QRS (more than 120 ms) and left ejection fraction less than 35% despite optimal medical therapy. Several have studies demonstrated the important role of echocardiography in patient selection for CRT, follow up and estimation of CRT effects, as well as the optimization of biventricular pacemaker. Basically, there are three types of cardiac asynchrony: interventricular asynchrony, between the right and left ventricle, intraventricular asynchrony, between the myocardial segments within the left ventricle and atrioventricular asynchrony, between the atria and ventricles. Although many echocardiographic techniques are used in patient selection for CRT, no ideal approach has yet been found. There are several techniques and parameters used in the assessment of myocardial asynchrony: two dimensional (2D) echocardiography, one dimensional echocardiography (M-mode), Doppler echocardiography, different modalities of tissue Doppler including Colour Coded Tissue Doppler Imaging - TDI, measurements of local tissue deformation indices (strain and strain rate), speckle tracking, 3D echocardiography, semiquantitative assessment of myocardial border, vector velocity imaging. Each of these techniques has advantages and limitations. A special accent in this revue is on the consensus report from the American Society of Echocardiography Dyssynchrony Writing group. According to this consensus report color coded tissue Doppler is the most appropriate technique for myocardial asynchrony estimation and patients selection for CRT. The same group recommended that definitive decision for CFT implantation should not be based only on echocardiographic analysis, but rather on the whole clinical aspect of the patient.

Cardiac resynchronization therapy (CRT) is an established treatment for heart failure patients who remain symptomatic despite optimal medical treatment, with left ventricular ejection fraction <35% and QRS complex with left bundle branch block morphology or duration ≥150 ms. Non-invasive imaging modalities contribute in the evaluation and selection of patients who are candidates for CRT. Evaluation of left ventricular mechanics and dyssynchrony, extent and location of myocardial scar and cardiac venous anatomy are important to estimate the likelihood of favourable response to CRT. This chapter will review the ‘why and how’ to assess cardiac dyssynchrony, myocardial scar, and cardiac venous anatomy, prior to CRT implantation.
