      Impact of final kissing balloon inflation on vessel healing following drug-eluting stent implantation: Insight from the optical coherence tomography sub-study of the J-REVERSE trial

      Background We sought to clarify the impact of final kissing inflation (FKI) after single stenting of bifurcation lesions on vessel healing. Methods From the J-REVERSE registry enrolling 303 bifurcation lesions treated with provisional single stenting using sirolimus- (SES) or everolimus-eluting stent (EES), 65 lesions treated with ( n = 30) and without ( n = 35) FKI underwent 9-month follow-up optical coherence tomography. Average stent eccentricity index (SEI: minimum/maximum stent diameter) and neointimal unevenness score (NUS: maximum/average neointimal thickness of the same cross-section) for the proximal, bifurcation, and distal segments were compared between FKI and non-FKI groups. Results At the proximal segment ...

    2. Differences in Vessel Healing Between Sirolimus- and Everolimus-Eluting Stent Implantation for Bifurcation Lesions: The J-REVERSE Optical Coherence Tomography Substudy

      Differences in Vessel Healing Between Sirolimus- and Everolimus-Eluting Stent Implantation for Bifurcation Lesions: The J-REVERSE Optical Coherence Tomography Substudy

      Background We aimed to clarify the differences in vessel healing after stenting of bifurcation lesions using sirolimus-eluting stents (SESs) or everolimus-eluting stents (EESs). Methods J apanese R egistry Study in Comparison Between Ever olimus-Eluting Stent and S irolimus- E luting Stent for the Bifurcation Lesion (J-REVERSE) is a prospective multicentre registry of 303 bifurcation lesions that were treated with provisional SES or EES with or without final kissing inflation. The first 115 lesions at selected study sites were predefined for inclusion in the optical coherence tomography (OCT) substudy, and 9-month follow-up OCT was conducted in 64 lesions (SES, n = 18 ...

The first 115 lesions at selected study sites were predefined for inclusion in the optical coherence tomography (OCT) sub-study and 9-month follow-up OCT was conducted in 64 lesions (SES: n = 18, EES: n = 46). In addition to standard OCT parameters, stent eccentricity index (SEI; minimum divided by the maximum stent diameter), neointimal ...

    4. Successful Treatment of Spontaneous Coronary Artery Dissection With Cutting Balloon Angioplasty as Evaluated With Optical Coherence Tomography

      Successful Treatment of Spontaneous Coronary Artery Dissection With Cutting Balloon Angioplasty as Evaluated With Optical Coherence Tomography

      A previously healthy 47-year-old pre-menopausal woman without any risk factors was admitted to our hospital with severe chest pain. Urgent coronary angiography showed a totally occlusive lesion in the middle of the left anterior descending coronary artery (LAD) with Thrombolysis In Myocardial Infarction (TIMI) flow grade 0. The other coronary arteries appeared normal. Immediate percutaneous coronary intervention (PCI) was performed because of ongoing chest pain and persistent ST-segment elevation. Intravascular ultrasonography showed an extensive intramural hematoma (Figure 1 ) and confirmed the presence of spontaneous coronary artery dissection (SCAD). We performed a cutting balloon angioplasty to create communications between the true ...
