Introduction
TRA has become the first choice for coronary intervention, with few
complications and more comfortable for patients [1,
2]. However, this novel access may lead to severe catheter twisting
and following manipulation may be required to unravel the catheter and
to avoid complications[3]. Re-rotate catheter can
handle minor problems, but there were also some cases so severe that
can’t be handled by this method but surgical intervention. In this
report, we describe our technique to handle catheter knot and report its
short-term outcome.
