Principles and Practical Strategies for Left Main Bifurcation & Trifurcation PCI: A Comprehensive Review<\/div>\n

Meta-analysis on left main bifurcation stenting strategies.<\/div>\n
<\/div>\n
1. Basic Definitions<\/div>\n
1. Bifurcation: LM divides into two branches (LAD + LCX).<\/span><\/div>\n
2. Trifurcation: LM divides into three branches (LAD + LCX + Ramus\/Intermediate).<\/span><\/div>\n
<\/div>\n
2. Clinical Importance<\/div>\n
1. LM disease supplies a large myocardial territory \u2192 very high risk.<\/span><\/div>\n
2. Bifurcation lesions are common; trifurcation lesions are rarer and more complex.<\/span><\/div>\n
3. More branches = higher risk of restenosis, side branch closure, and stent overlap.<\/span><\/div>\n
<\/div>\n
3. Treatment Options for LM Disease<\/div>\n
1. PCI (stenting): preferred if anatomy is suitable; always IVUS\/OCT-guided.<\/span><\/div>\n
2. CABG: gold standard for very complex or high SYNTAX score lesions.<\/span><\/div>\n
3. CABG in acute STEMI:<\/span><\/div>\n
\u2022 Primary PCI is the standard of care.<\/span><\/div>\n
\u2022 CABG is considered only if:<\/span><\/div>\n
* PCI fails.<\/div>\n
* Mechanical complications occur (e.g., rupture, severe valve dysfunction).<\/div>\n
* LM occlusion unsuitable for PCI (diffuse\/calcified lesions, poor distal vessels).<\/div>\n
<\/div>\n
4. LM Occlusion with Heavy Thrombus Burden<\/div>\n
1. First step: aspiration thrombectomy.<\/span><\/div>\n
2. If residual severe stenosis \u2192 cautious small-balloon predilatation (1.5\u20132 mm, low pressure).<\/span><\/div>\n
3. Stent implantation only after thrombus minimized.<\/span><\/div>\n
4. If no-reflow or hemodynamic collapse:<\/span><\/div>\n
\u2022 Stop device maneuvers.<\/span><\/div>\n
\u2022 Give intracoronary adenosine, verapamil\/diltiazem, or nitroprusside.<\/span><\/div>\n
\u2022 Provide hemodynamic support (fluids, pressors, IABP\/Impella if available).<\/span><\/div>\n
5. Antithrombotics:<\/span><\/div>\n
\u2022 Cangrelor preferred if CABG possible (bridging substitute for ticagrelor\/prasugrel\/clopidogrel; rapid onset and offset; temporary replacement for oral P2Y12 while aspirin continued).<\/span><\/div>\n
\u2022 Aspirin always continued.<\/span><\/div>\n
\u2022 GP IIb\/IIIa inhibitors (e.g., tirofiban\/Aggrastat): avoided if CABG possible because their effect lasts hours, increasing surgical bleeding risk.<\/span><\/div>\n
6. If PCI fails \u2192 CABG rescue<\/span><\/div>\n","protected":false},"excerpt":{"rendered":"
