Why the study?
Does flushing transseptal sheaths with high-concentration heparin reduce thrombus formation in patients undergoing left atrial ablation?
Does flushing transseptal sheaths with high-concentration heparin reduce thrombus formation in patients undergoing left atrial ablation?
Flushing transseptal sheaths with high-concentration heparin (1,000 U/cc) significantly reduces the risk of intraprocedural thrombus formation compared to standard flush during left atrial ablation.
No takes yet. Share an insight, caveat, or question.
High-concentration heparin flush was associated with lower thrombus rates; leaves open whether randomized trials should test routine adoption in left atrial ablation.
Maleki et al. (2005) studied this question.
