Key result
Ethanol injection into the vein of Marshall resulted in contrast medium extravasation in 22.7% of patients, with severe pericardial effusions occurring in small patients with poor compliant hearts.
Why the study?
Ethanol injections into the vein of Marshall are a therapeutic option for atrial tachyarrhythmias, but the safety and factors affecting potential complications remain to be determined.
What are the safety and potential complications of ethanol injection into the vein of Marshall in patients with drug-resistant atrial fibrillation?
Observational (n=88)
What are the safety and potential complications of ethanol injection into the vein of Marshall in patients with drug-resistant atrial fibrillation?
Ethanol injection into the vein of Marshall can cause contrast extravasation and pericardial effusion, particularly in smaller patients with poor compliant hearts.
No takes yet. Share an insight, caveat, or question.
May warrant caution in smaller patients during VOM ethanol injection; leaves open need for prospective validation of risk stratification.
Kato et al. (2019) conducted an observational in Drug-resistant atrial fibrillation (n=88). Ethanol injection into the vein of Marshall (EIM) was evaluated on Extravasation of contrast medium with capillary rupture. Ethanol injection into the vein of Marshall resulted in contrast medium extravasation in 22.7% of patients, with severe pericardial effusions occurring in small patients with poor compliant hearts.
