Benefit of cardiac resynchronization therapy to a patient with a narrow QRS complex and ventricular dyssynchrony identified by tissue synchronization imaging.
This report described an 81-year-old woman with severe symptomatic heart failure, reduced ejection fraction, mitral regurgitation, and an electrocardiographic QRS width of 118 ms who had ventricular dyssynchrony identified by echocardiographic tissue synchronization imaging. Because of her severe heart failure symptoms on maximal medical therapy, referral to implant a defibrillator, and mechani...
متن کاملCardiac resynchronization therapy in patients with a narrow QRS complex.
OBJECTIVES The purpose of this study was to evaluate the effects of cardiac resynchronization therapy (CRT) in heart failure patients with narrow QRS complex (<120 ms) and evidence of left ventricular (LV) dyssynchrony on tissue Doppler imaging (TDI). BACKGROUND Cardiac resynchronization therapy is beneficial in selected heart failure patients with wide QRS complex (> or =120 ms). Patients wi...
متن کاملFragmented QRS and Ventricular Dyssynchrony in a Patient Treated with Cardiac Resynchronization Therapy
Cardiac resynchronization is an established treatment modality in patients with heart failure NYHA class III-IV on optimal medical treatment, QRS duration of at least 120-130 ms and ejection fraction <35%. Nevertheless, a proportion of patients, up to 20-30%, are considered non-responders as they are not improved by cardiac resynchronization therapy (CRT). This report describes a 63-year-old pa...
متن کاملAssociation of intraventricular mechanical dyssynchrony with response to cardiac resynchronization therapy in heart failure patients with a narrow QRS complex
AIMS current criteria for cardiac resynchronization therapy (CRT) are restricted to patients with a wide QRS complex (>120 ms). Overall, only 30% of heart failure patients demonstrate a wide QRS complex, leaving the majority of heart failure patients without this treatment option. However, patients with a narrow QRS complex exhibit left ventricular (LV) mechanical dyssynchrony, as assessed with...
متن کاملCardiac resynchronization therapy in patients with a narrow QRS.
Although cardiac resynchronization therapy (CRT) is indicated in patients with moderate to severe heart failure with a wide QRS complex (> 120 ms), current guidelines exclude many heart failure patients with a narrow QRS. Detecting mechanical dyssynchrony on echocardiography has become a promising tool in selecting patients with a narrow QRS who may respond to CRT. Several small single-center s...
