Background: Coronary artery calcification (CAC) presents unique challenges for percutaneous coronary intervention. Calcium appears as a signal-poor region with well-defined borders by frequency-domain optical coherence tomography (FD-OCT). The objective of this study was to demonstrate the accuracy intravascular FD-OCT determine distribution CAC. Methods and Results: Cadaveric arteries were imaged using at 100-μm frame interval. Arteries subsequently frozen, sectioned 20-μm intervals Case...
To investigate safety and feasibility of imaging unprotected left main (ULM) using frequency-domain optical coherence tomography (FD-OCT) compared with intravascular ultrasound (IVUS).IVUS has been used to assess guide percutaneous coronary intervention (PCI) ULM disease. FD-OCT offers 10-fold higher axial resolution than IVUS its high-speed image acquisition obviates the need for proximal balloon occlusion.We prospectively enrolled 35 consecutive patients assessments were attempted pre-...
Worldwide, many hundreds of thousands stents are implanted each year to revascularize occlusions in coronary arteries. Intravascular optical coherence tomography is an important emerging imaging technique, which has the resolution and contrast necessary quantitatively analyze stent deployment tissue coverage following implantation. Automation needed, as current, it takes up 16 h manually images struts from a single pullback. For automated strut detection, we used image formation physics...
Background: This study assesses clinical outcomes after drug-eluting balloon treatment for recurrent in-stent restenosis lesions based on the number of metallic layers. Methods and Results: We enrolled 304 consecutive patients (333 lesions) treated with percutaneous coronary intervention using between March 2014 June 2015. Per stent layers previously implanted to lesion, were categorized into 3 groups, 1 layer (1L), 166 patients; 2 (2L), 87 ≥3 (≥3L), 51 patients. The end points major adverse...
Coronary artery aneurysm (CAA) is occasionally detected on a small percentage of coronary angiography or multi-detector computed tomography (MDCT). CAA itself considered benign entity despite the potential risks rupture, thromboembolism, and compression surrounding structures. However, optimal management including other vascular comorbidity has yet to be fully clarified. The aim this study was evaluate cardiovascular events in patients with observational group. Between January 2010 August...
A 60-year-old man with a history of radiation therapy 28 years ago for benign disease (an aneurysmal bone cyst) was admitted dyspnea and dysphagia. Computed tomography showed an 8-cm tumor invading the trachea esophagus. His condition declined rapidly, he died on day 27 hospitalization. Autopsy revealed radiation-induced osteosarcoma. Radiation-induced sarcoma can develop even after radiotherapy diseases, in which case latency period might be longer. Furthermore, prognosis depends location...
There is little data on percutaneous coronary intervention (PCI) using rotational atherectomy (Rota) for severely calcified unprotected left main (ULM) lesions.Between January 2005 and August 2011, 64 consecutive patients who underwent drug-eluting stent implantation Rota were retrospectively evaluated. Of these, 54.7% 20.3% had diabetes undergoing hemodialysis (HD), respectively. The mean EuroSCORE SYNTAX score was 5.6 35.4, Procedural success, defined as residual stenosis <30%, achieved in...
Structured abstract Background Immunoglobulin G4-related disease (IgG4-RD) is a systemic immune-mediated inflammatory that infrequently involves the coronary arteries. Given pericoronary adipose tissue (PCAT) attenuation reflects degree of inflammation in arteries, monitoring with PCAT may enable evaluation activity IgG4-related periarteritis (CP). Case Summary A 58-year-old man history IgG4-RD presented ST-segment elevation myocardial infarction. Emergent angiography revealed severe...
The presence of chronic total occlusion the right coronary artery (CTO-RCA) in patients undergoing percutaneous interventions for unprotected left main (ULM) disease may affect prognosis. In this study, we evaluated immediate results and follow-up with ULM-percutaneous or without associated CTO-RCA.Between March 2002 December 2008, a 568 consecutive ULM stenosis treated drug-eluting stent were included analysis. mean EuroScore SYNTAX scores 4.05±2.62 28.12±10.82, respectively. Of these, 522...
Background— There are only little data available on the comparison of clinical outcomes between a 1-stent strategy (1-SS) and 2-stent (2-SS) for percutaneous coronary intervention in unprotected distal left main disease. Methods Results— Between April 2005 August 2011, we recruited 937 consecutive patients treated with drug-eluting stents (1-SS, 608 patients; 2-SS, 329 patients). Major adverse cardiovascular events were defined as all-cause death, myocardial infarction, or target lesion...
Background In‐stent restenosis (ISR) remains one of the main limitations for percutaneous coronary intervention unprotected distal left (UDLM). This study aims to demonstrate impact main‐branch ISR (MB‐ISR) on mortality and clarify optimal strategy. Methods Between 2002 2008, 482 consecutive UDLM patients treated with drug eluting stent (sirolimus paclitaxel) were evaluated. Results During follow‐up period (median 52.6 months), MB‐ISR occurred in 29, SB‐ISR 65, MB/SB‐ISR 24. Multivariable...
Objectives This study aimed to investigate the long‐term outcomes following mini‐crush versus culotte stenting with drug‐eluting stents (DES) for treatment of unprotected left main coronary artery (LMCA) disease. Background Both and are considered efficacious options when a planned 2‐stent strategy is deemed necessary LMCA However, there limited data available regard clinical each in this setting. Methods Between July 2002 November 2013, 225 patients were identified. 135 treated technique,...
There are only limited studies reporting clinical outcomes after bioresorbable vascular scaffold (BVS; Absorb; Abbott Vascular, Santa Clara, CA) implantation for coronary chronic total occlusions (CTO). The aim of this study was to evaluate the real-world feasibility and safety BVS treatment CTO.We retrospectively evaluated CTO cases treated with from a multicenter registry. primary end point target lesion failure defined as composite cardiac death, vessel myocardial infarction, clinically...
