    1. Optical coherence tomography for strategy planning and staged optimization of spontaneous coronary artery dissection

      Optical coherence tomography for strategy planning and staged optimization of spontaneous coronary artery dissection

      A 49-year-old non-pregnant female, taking no hormonal replacement therapy, smoker, and with a family history of myocardial infarction, was admitted with inferior ST-segment elevation myocardial infarction. Angiography of the right coronary artery demonstrated a diffuse tubular narrowing in the proximal segment ( A ). A spontaneous coronary artery dissection (SCAD), type 2A, was suspected. Optical coherence tomography (OCT) demonstrated a large dissection, with the presence of a false double lumen and an associated diffuse circular haematoma, resulting in the compression of the true lumen ( B – C – D ). Because of ongoing ischaemia (ST-elevation and severe chest pain), the decision to stent the dissection ...

    2. You can’t judge a book by its cover: a trivial angiographic image, an optical coherence tomography run and a surprising ending

      You can’t judge a book by its cover: a trivial angiographic image, an optical coherence tomography run and a surprising ending

      A 75 year-old man was hospitalized for recent onset of low-threshold effort dyspnoea and moderate reduction of the left ventricular ejection fraction (39%, 2 weeks before it measured 55%) with infero-postero-lateral ipokinesia and severe mitral regurgitation. His medical history included three-vessel coronary artery disease treated by percutaneous coronary intervention (PCI) and implantation of drug eluting stents (DES) on the mid left anterior descending coronary artery, the mid left circumflex coronary artery and the distal right coronary artery (RCA).

    3. Predictive value of plaque morphology assessed by frequency-domain optical coherence tomography for impaired microvascular perfusion after elective stent implantation: the intracoronary electrocardiogram study

      Predictive value of plaque morphology assessed by frequency-domain optical coherence tomography for impaired microvascular perfusion after elective stent implantation: the intracoronary electrocardiogram study

      Aims This study was undertaken to assess the association between plaque features at culprit lesions assessed by frequency-domain optical coherence tomography (FD-OCT) and impaired microvascular perfusion estimated by intracoronary electrocardiogram (IcECG) after elective percutaneous coronary intervention (PCI). Furthermore, we investigated whether IcECG could predict future cardiac events. Methods and results This study consisted of 84 patients who underwent both FD-OCT and IcECG during PCI. Patients were classified into two groups based on ST-segment elevation (ST-E) on IcECG after the procedure; ST-E (−) group ( n  = 53) and ST-E (+) group ( n  = 31). Minimum fibrous cap thickness was significantly thinner in the ST-E (+) group ...

    4. Bas-relief in three dimensional optical coherence tomography: a novel sign after subintimal scaffolding in a chronic total occlusion

      Bas-relief in three dimensional optical coherence tomography: a novel sign after subintimal scaffolding in a chronic total occlusion

      A 69-years-old female with stable angina underwent percutaneous intervention of a chronic total occlusion (CTO) in the proximal right coronary artery (RCA) ( Panel A, Supplementary material online , Video S1 ). Septal collaterals supplied the distal vessel (Rentrop 3, CC1) ( Supplementary material online , Video S2 ).

    5. Fate of post-procedural malapposition of everolimus-eluting polymeric bioresorbable scaffold and everolimus-eluting cobalt chromium metallic stent in human coronary arteries: sequential assessment with optical coherence tomography in ABSORB Japan trial

      Fate of post-procedural malapposition of everolimus-eluting polymeric bioresorbable scaffold and everolimus-eluting cobalt chromium metallic stent in human coronary arteries: sequential assessment with optical coherence tomography in ABSORB Japan trial

      Aims The natural course of post-procedural incomplete strut apposition (ISA) after the implantation of bioresorbable scaffolds (BVS) remains unknown. The purpose of the present study was to evaluate the fate of post-procedural ISA after everolimus-eluting Absorb BVS in comparison with the second-generation everolimus-eluting cobalt chromium stent (CoCr-EES). Methods and results Fate of post-procedural ISA was evaluated by serial optical coherence tomography (OCT) in the ABSORB Japan randomized trial [OCT-1 subgroup: 110 paired lesions of post-procedure and 2-year follow-up (BVS 73 lesions vs. CoCr-EES 37 lesions)] with respect to ISA distance. Post-procedure ISA struts were categorized into either ‘resolved’ or ‘persistent ...
