Alerts operators to conduction injury risk during left catheterization; leaves open incidence, predictors, and outcomes in larger cohorts.
Case Report (n=3)
Left-sided cardiac catheterization can induce transient LBBB even in patients with normal baseline conduction, highlighting the need for careful ECG monitoring during the procedure.
Shimamoto et al. (1998) conducted a case report in Patients undergoing left-sided cardiac catheterization (n=3). Left-sided cardiac catheterization was evaluated on Development of left bundle branch block (LBBB). Left-sided cardiac catheterization induced transient left bundle branch block lasting 2-4 minutes in 3 patients without pre-existing conduction abnormalities.
