Key result
Retrograde left ventricular catheterization in a patient with severe aortic stenosis and baseline bifascicular block was complicated by transient complete heart block that resolved spontaneously.
Case Report (n=1)
Retrograde left ventricular catheterization can rarely cause transient complete heart block, particularly in patients with pre-existing bifascicular block.
May support heightened monitoring in severe AS with bifascicular block; leaves open need for systematic risk assessment.
Complete heart block (CHB) following retrograde left ventricular catheterization is uncommon. We report a case of transient CHB in a patient with severe aortic stenosis and bifascicular block on the baseline surface electrocardiogram during retrograde left ventricular catheterization. The block resolved spontaneously without sequelae. A review of the literature using MedLine was performed and recommendations for temporary and permanent pacing are outlined.

Shammas et al. (1994) conducted a case report in Severe aortic stenosis and bifascicular block (n=1). Retrograde left ventricular catheterization was evaluated on Complete heart block. Retrograde left ventricular catheterization in a patient with severe aortic stenosis and baseline bifascicular block was complicated by transient complete heart block that resolved spontaneously.
