Speckle-tracking echocardiography identified depressed peak systolic strain in the septal apical and mid-septal segments, suggesting a focal myocardial insult corresponding to the distal right bundle of His.

Does speckle-tracking echocardiography identify focal myocardial insults in patients with isolated complete right bundle branch block?
Speckle-tracking echocardiography may help identify focal myocardial insults corresponding to the right bundle of His in patients with isolated complete right bundle branch block.
Objective: Isolated complete right bundle branch block (CRBBB) is a known ECG finding in apparently healthy adults.However, the etiology of CRBBB is studied poorly and its prognosis still debatable.We aimed to demonstrate speckle-tracking imaging findings in a patient with CRBBB.Case presentation: An apparently healthy lady was found to have a CRBBB on an incidental ECG.Routine echocardiography showed normal cardiac anatomy and function.Speckle-tracking echocardiography depicted preserved global strain of the left ventricle with depressed peak systolic strain of septal apical and mid-septal segments.We present a focal myocardial insult in the area corresponding to the anatomy the right bundle of His.Such correlation may explain the CRBBB present in the otherwise healthy patient.Conclusion: Speckle-tracking echocardiography in complete right bundle branch block may help to identify the etiology of this conduction disturbance and assist in making the prognosis.
Petrov et al. (Thu,) conducted a case report in Isolated complete right bundle branch block (n=1). Speckle-tracking echocardiography was evaluated on Myocardial strain patterns. Speckle-tracking echocardiography identified depressed peak systolic strain in the septal apical and mid-septal segments, suggesting a focal myocardial insult corresponding to the distal right bundle of His.
