The differential impact of intraventricular and interventricular dyssynchrony on left ventricular remodeling and function in patients with isolated left bundle branch block
نویسندگان
چکیده
Interventricular dyssynchrony evaluated with cardiac magnetic resonance is an independent predictor of systolic dysfunction and left ventricular remodeling while intraventricular dyssynchrony is an independent predictor of LV diastolic dysfunction in patients with isolated LBBB. Comprehensive evaluation of both these parameters of dyssynchrony would be useful in selecting patients for cardiac resynchronization therapy.

Mechanical Dyssynchrony is Similar in Different Patterns of Left Bundle-Branch Block
BACKGROUND Left bundle-branch block (LBBB) and the presence of systolic dysfunction are the major indications for cardiac resynchronization therapy (CRT). Mechanical ventricular dyssynchrony on echocardiography can help identify patients responsive to CRT. Left bundle-branch block can have different morphologic patterns. OBJECTIVE To compare the prevalence of mechanical dyssynchrony in differ...
متن کاملLeft ventricular dyssynchrony from right ventricular pacing depends on intraventricular conduction pattern in intrinsic rhythm.
AIMS Right ventricular pacing (RVP) prolongs ventricular activation and may induce mechanical dyssynchrony. We hypothesized that the severity of RVP-associated ventricular mechanical dyssynchrony may depend on the intrinsic intraventricular conduction pattern. METHODS AND RESULTS Sixty-five patients with a single- or dual-chamber RV pacemaker were included. Forty-seven patients with ejection ...
متن کاملInterventricular and intraventricular dyssynchrony are common in heart failure patients, regardless of QRS duration.
AIMS The study aimed at evaluating the prevalence of interventricular and intraventricular contractile dyssynchrony in heart failure patients with either normal or prolonged QRS duration. METHODS AND RESULTS Echocardiography and tissue Doppler imaging (TDI) were performed in 158 consecutive patients with advanced left ventricular dysfunction (LVEF<35%); 61 patients had a normal QRS duration (...

OBJECTIVES The study evaluated the prognostic value of interventricular and intraventricular dyssynchrony in idiopathic dilated cardiomyopathy (IDC). BACKGROUND Biventricular pacing is an emerging treatment for patients with dilated cardiomyopathy and ventricular dyssynchrony. The prognostic values of interventricular and intraventricular dyssynchrony have not been previously compared. METHODS ...
متن کاملThe role of electrocardiography in the elaboration of a new paradigm in cardiac resynchronization therapy for patients with nonspecific intraventricular conduction disturbance
Cardiac resynchronization therapy (CRT) is associated with a favorable outcome only in patients with left bundle branch block (LBBB) pattern and in patients with a QRS duration > 150 ms, in patients with non-LBBB pattern with a QRS duration of 120-150 ms usually is not beneficial. After adjusting for QRS duration, QRS morphology was no longer a determinant of the clinical response to CRT. In co...
