2021年5月1日 · Echocardiography (2-D echo) is now the preferred imaging modality for patients with left bundle branch block (LBBB). The prevalence of potential etiologies of LBBB has not been extensively studied by cardiac MRI (CMR). An institutional imaging database was queried for all patients with LBBB who had undergone CMR, constituting the study cohort.

Left bundle branch block (LBBB) is a ventricular conduction delay with high prevalence. Aim of our study is to identify possible recurring patterns of artefacts in late gadolinium enhancement (LGE) imaging in patients with LBBB who undergo cardiac magnetic resonance imaging (MRI) and to define parameters of mechanical dyssynchrony associated ...

2023年3月13日 · A form of interventricular conduction defect most often diagnosed on the electrocardiogram, the presence of a left bundle branch block (LBBB) disrupts the normal sequence of ventricular depolarization. Aberrant conduction in the left bundle branch producing a conduction block is most often associated with 1;

2022年10月20日 · Background: Left bundle branch block (LBBB) is a ventricular conduction delay with high prevalence. Aim of our study is to identify possible recurring patterns of artefacts in late gadolinium enhancement (LGE) imaging in patients with LBBB who undergo cardiac magnetic resonance imaging (MRI) and to define parameters of mechanical dyssynchrony ...

Left bundle-branch block (LBBB) is common in patients with heart disease, and in this clinical setting it may progressively lead to left ventricular dysfunction and worsen the prognosis [1–5]. By contrast, LBBB is very rare in young individuals without clinical evidence of heart disease.

Left bundle branch block (LBBB) is frequently associated with structural heart disease, and predicts higher rates of morbidity and mortality. In patients with cardiomyopathy (ejection fraction <35%) and LBBB, current guidelines recommend cardiac ...

A left bundle branch block (LBBB) occurs when conduction through the left bundle branches is slowed down or completely absent, resulting in delayed depolarization of the left ventricular (LV) myocardium . There are many underlying causes, and LBBB is rather common with a prevalence that increases with age (2, 3).

Left bundle branch block (LBBB) can be caused by special patterns of coronary disease such as distal LAD occlusion combined with right coronary artery (RCA) obstruction, or transient bradycardia-related LBBB due to increased parasympathetic tone with RCA occlusion.

2012年2月1日 · Stress CMR imaging has high sensitivity and negative predictive value in the identification of CAD, in patients with complete LBBB. It can also assess infiltrative cardiomyopathies. Stress CMR appears to provide a better comprehensive assessment than nuclear scintigraphy in patients with LBBB.

2018年2月1日 · We assessed left ventricular (LV) structural, functional, and tissue abnormalities associated with intraventricular conduction left bundle disease (LBD), including left anterior hemiblock or complete left bundle branch block, in a cohort of patients with NIC submitted to cardiovascular magnetic resonance.
