Coronary bifurcation stenoses: the kissing balloon Probe technique via a single guiding catheter.

A new technique employing two balloon probes via a single (large-lumen) guiding catheter is described. Examples involving the left anterior descending, diagonal, left main (protected), left circumflex-obtuse marginal, and atrioventricular branches and the right coronary artery-posterior descending and posterolateral branches are described and illustrated. This new technology (balloon probes and large-lumen guiding catheter) permits an effective and simplified alternative to the use of the single-guide/two-wire and double-guide/two-dilatation catheter-wire approaches in selected cases in which significant branch vessels (vis-a-vis myocardial regional blood supply) are at risk.
