Key result
Contrast injection during PCI transiently resolves Mobitz type 2 AV block in stable angina.
Why the study?
The prevalence and management of AV block in the setting of chronic myocardial ischemia remains unclear.
Case Report (n=1)
This case report highlights an unusual phenomenon where contrast injection during PCI temporarily resolved ischemia-induced Mobitz Type 2 AV block.
Single-case observation warrants no practice change; leaves open whether intracoronary contrast modulates AV conduction in CAD.
There are many cases in the literature concerning the occurence of atrioventricular block in acute myocardial infarction. The prevelance and management of AV block in the setting of chronic myocardial ischemia remains unclear. Our case presented with stable angina pectoris. Treadmill test revealed Mobitz Type 2 AV block which disappeared with contrast injection and re-occured after injection during PCI.

Si̇nan et al. (2016) conducted a case report in Stable angina pectoris with Mobitz Type 2 AV block (n=1). Contrast injection was evaluated on Resolution of AV block. Contrast injection during percutaneous coronary intervention temporarily resolved Mobitz Type 2 AV block in a patient with stable angina pectoris.
