Can you have surgery with left anterior fascicular block?

In our case, the patient’s preoperative ECG showed left anterior fascicular block and sinus bradycardia. This is usually regarded as a low risk for surgery when the patient has normal ventricular function and is asymptomatic.

How serious is a left anterior fascicular block?

A cardiac condition called left anterior fascicular block (LAFB), in which scarring occurs in a section of the left ventricle, may not be as benign as currently thought and could increase the likelihood of heart failure, sudden cardiac death or atrial fibrillation.

Can I have surgery with LBBB?

These data suggest that the presence of BBB does not significantly increase the likelihood of cardiac complications following surgery, but that patients with LBBB may not tolerate the stress of perioperative noncardiac complications.

Is left anterior fascicular block benign?

Left anterior fascicular block (LAFB) is considered a failure or delay of conduction in the left anterior fascicle. Despite the fact that little is known about the long-term prognosis associated with LAFB, it has generally been thought of as a benign electrocardiographic (ECG) finding.

Is the left anterior fascicular block ( LAFB ) benign?

To the Editor Left anterior fascicular block (LAFB) is considered a benign electrocardiographic (ECG) finding, but its long-term consequences have not been comprehensively studied. Conduction blocks occur due to conduction system fibrosis and are associated with myocardial fibrosis, even in the absence of other cardiovascular disease.

Can a catheter insertion cause a left anterior fascicular block?

Castellanos et al. 32 observed cases in which catheter insertion into the right ventricle produced a transient mechanical RBBB that was associated in two cases with left anterior fascicular block and in two cases with left posterior fascicular block.

Is there a bifascicular block in the left posterior fascicles?

Bifascicular block. Note the presence of right bundle branch block with left posterior fascicular block. Trifascicular block refers to conduction delay in the right bundle branch with delay in either the main left bundle branch or in both the left anterior and the left posterior fascicles.

What causes left anterior fascicular block in congenital heart disease?

In patients with congenital heart disease, abnormal left axis deviation is most commonly seen in patients with endocardial cushion defects, which include atrial septal defect of the primum type, AV canal, and a common atrium (Figure 6-6).
