Cardiac resynchronization therapy guided by cardiovascular magnetic resonance

چکیده
Cardiac resynchronization therapy (CRT) is an established treatment for patients with symptomatic heart failure, severely impaired left ventricular (LV) systolic dysfunction and a wide (> 120 ms) complex. As with any other treatment, the response to CRT is variable. The degree of pre-implant mechanical dyssynchrony, scar burden and scar localization to the vicinity of the LV pacing stimulus are known to influence response and outcome. In addition to its recognized role in the assessment of LV structure and function as well as myocardial scar, cardiovascular magnetic resonance (CMR) can be used to quantify global and regional LV dyssynchrony. This review focuses on the role of CMR in the assessment of patients undergoing CRT, with emphasis on risk stratification and LV lead deployment.

Cardiac resynchronization therapy guided by late gadolinium-enhancement cardiovascular magnetic resonance
BACKGROUND Myocardial scarring at the LV pacing site leads to incomplete resynchronization and a suboptimal symptomatic response to CRT. We sought to determine whether the use of late gadolinium cardiovascular magnetic resonance (LGE-CMR) to guide left ventricular (LV) lead deployment influences the long-term outcome of cardiac resynchronization therapy (CRT). METHODS 559 patients with heart ...
متن کاملMagnetic resonance criteria for future trials of cardiac resynchronization therapy.
Current patient selection criteria for Cardiac Resynchronization Therapy (CRT), an efficacious treatment for heart failure, include no measure of disconjugate cardiac contractility other than prolonged QRS on electrocardiogram. Using cardiac magnetic resonance imaging, we examined the roles of cardiac asymmetry, asynchrony, and circumferential strain in DCC with the principal aim of generating ...
متن کاملNon-invasive cardiac magnetic resonance and electrical myocardial imaging assessment of CRT in patients with heart failure and left bundle branch block
Introduction CRT is an effective treatment for patients with heart failure and intraventricular conduction delay. However, clinical non-response rates remain unacceptably high; emphasizing the need for improved selection criteria. Central to the underlying mechanism of resynchronization is the relationship between mechanical and electrical activation. The purpose of this study was to demonstrat...
متن کاملRelationship between mechanical dyssynchrony and intra-operative electrical delay times in patients undergoing cardiac resynchronization therapy
BACKGROUND It is important to understand the relationship between electrical and mechanical ventricular activation in CRT patients. By measuring local electrical activation at multiple locations within the coronary veins and myocardial contraction at the same locations in the left ventricle, we determined the relationship between electrical and mechanical activation at potential left ventricula...

AIMS Left ventricular (LV) lead positioning for cardiac resynchronization therapy (CRT) is largely empirical and operator-dependent. Our aim was to determine whether cardiac magnetic resonance (CMR)-guided CRT may improve the acute and the chronic response. METHODS AND RESULTS CMR-derived anatomical models and dyssynchrony maps were created for 20 patients. The CMR targets (three latest activ...
