The objective of the present study is to determine the usefulness of an approach to the treatment of LAD ostial lesions that we term the floating-stent technique. Angiographic information on this seems limited. Simultaneously, we studied the carinal area in detail ie, the confluence of distal LMCA, Cx origin, and LAD origin and analyzed atheromous plaque distribution and carina morphology through a longitudinal reconstruction permitting optimal visualization of the bifurcation.

We excluded patients with minimal disease at the level of the distal LMCA and ostial Cx and 21 patients with similar lesions who, during the first 2 years of the study, received a stent covering the distal LMCA and proximal LAD segments. Angiographic and ultrasound characteristics indicate substantial differences in vessel caliber between distal LMCA and proximal LAD tapering, 0. Our technique is quick, effective, and technically simple approach for successful treatment of LAD Ostial lesion.
There was no oscillation of the LAD stent during positing and thus its help for precise LAD Ostial placement (Figure 4, Figure 5).
Then keeping. Strategies for LAD Ostial PCI are Proximal strut of stent extended into distal LM, Stenting Covering the Distal LMCA, Precise Location at Ostium.
The study involved 71 patients with ostial LAD lesions who underwent implantation of a drug-eluting stent in the LAD, which totally or partially covered the ostium.
Sort By relevancy By date. We have no angiographic follow-up of asymptomatic patients treated with the floating-stent technique although, given the localization of the lesion, we believe adverse events are unlikely to occur with no clinical warning. Post procedural course was uneventful, and the patient was discharged after 24 hours.
C: another ostial LAD lesion with angiographic characteristics similar to those illustrated in A. In contrast, the floating-stent technique is simpler and seems to offer good results too.
BACKGROUND: Although drug-eluting stents (DES) have reduced Overall TLR and TLR-LM rates were higher in the focal ostial LAD stenting group.

Low atmosphere balloon dilatation facilitates damage correction through repositioning the carina, but the kissing balloon technique is not employed to avoid barotrauma in the distal LMCA, which is not protected by the stent.

We measured external elastic lamina area, luminal area and plaque load at three levels: distal segment of reference, segment of maximum stenosis and distal LMCA. A: baseline and post-treatment angiography; the arrow indicates focal damage induced in the Cx origin after stent implantation.

|In most patients, stent implantation was without predilatation.
B: angiographic results after floating-stent implantation. This contradicts previous hypotheses attributing Cx ostial lesions to stent-induced plaque displacement. Our technique is quick, effective, and technically simple approach for precise stent placement at LAD. Forgot Your Password?
