Ostial side branch stenting (esp. ostial diagonal): algorithms and cases -Elias Hanna

0:00 Types of ostial side branch disease, cases where a perfect T can be done.
5:53 and 9:13 Algorithm for LAD-diagonal or LCx-OM with shallow angle: semi-culotte, re-cross into LAD and balloon, inverted TAP if needed
18:04 Cases
19:17 Two cases of crush stenting with pitfalls: difficult balloon recrossing through crushed stent.
20:45 The one caveat of semi-culotte
26:29 Inverted TAP case
30:46 Planned standard TAP case (vs provisional stenting). Technical comments about TAP

***Perfect T vs TAP:
T stenting: branch needs to be close to 90 degrees and  a single stent can be done for isolated ostial SB disease
vs. TAP: can be done for narrower angles, even 40-60, but only after MB has been stented (TAP is part of 2-stent strategy, whether provisional or planned)
