Coronary Stent Thrombosis — Predictors and Prevention

2020

BACKGROUND: Stent thrombosis (ST) is a dreaded complication after stent implantation and is associated with a mortality between 5% and 45%. The mechanisms by which ST arises are complex. Because of the seriousness of this situation, all physicians should have at least basic knowledge of it. In this article, we present the risk factors for ST and discuss some innovative approaches to its treatment. METHODS: This review is based on pertinent articles retrieved by a selective search in PubMed, and on current international guidelines and expert recommendations. RESULTS: The frequency of ST has been markedly lowered by technical advances in coronary stenting and by the implementation of modern i…

Choice of CTO scores to predict procedural success in clinical practice. A comparison of 4 different CTO PCI scores in a comprehensive national regis…

2021

Background We aimed to compare the performance of the recent CASTLE score to J-CTO, CL and PROGRESS CTO scores in a comprehensive database of percutaneous coronary intervention of chronic total occlusion procedures. Methods Scores were calculated using raw data from 1,342 chronic total occlusion procedures included in REBECO Registry that includes learning and expert operators. Calibration, discrimination and reclassification were evaluated and compared. Results Mean score values were: CASTLE 1.60±1.10, J-CTO 2.15±1.24, PROGRESS 1.68±0.94 and CL 2.52±1.52 points. The overall percutaneous coronary intervention success rate was 77.8%. Calibration was good for CASTLE and CL, but not for J-CTO…

Five-Year Results of the Bioflow-III Registry:Real-World Experience with a Biodegradable Polymer Sirolimus-Eluting Stent

2018

Abstract Purpose We aimed to assess long-term safety and performance of the Orsiro sirolimus-eluting coronary stent with biodegradable polymer in a large unselected population and in pre-specified subgroups. Methods BIOFLOW-III is a prospective, multicenter, international, observational registry with follow-up visits scheduled at 6 and 12 months, and at 3 and 5 years ( NCT01553526 ). Results 1356 patients with 1738 lesions were enrolled. Of those, 392 (28.9%) declined to participate in the study extension from 18 months to 5 years, 37 (2.7%) withdrew consent, and 89 (6.6%) were lost to follow-up. At 5-years, Kaplan-Meier estimates of target lesion failure, defined as a composite of cardiac …

Lobar lung resection in elderly patients with non-small cell lung carcinoma: impact of cardiac comorbidity on surgical outcome.

2013

Principles The aim of this study was to evaluate the impact of cardiac comorbidity on the perioperative morbidity and mortality after lobar lung resection for lung cancer in patients aged 70 years and older. Methods The medical records of all 68 patients ≥70 years, who underwent lobar lung resection for non-small cell lung cancer (NSCLC) from 2003 to 2011 at our department, were reviewed retrospectively. Twenty-two patients with a mean age of 76.3 years had cardiac comorbidities (Group A) including previous cardiac operations in 4 patients, previous myocardial infarction in 5 patients, previous coronary stent insertion in 3 patients, medically treated coronary artery disease in 10 patients …

Noninvasive Visualization of an Apparent Patent Intracoronary Stent by Transesophageal Echocardiography

1995

In the area of increasing interventional techniques there is a need for noninvasive imaging modalities to provide postinterventional follow-up. We were able to visualize the apparent patency and measure the dimensions of an intracoronary Palmaz-Schatz stent in the left circumflex coronary artery using transesophageal two-dimensional echocardiography. This report indicates the potential of echocardiography to directly assess coronary stents.

9-Month Clinical and Angiographic Outcomes of the COBRA Polyzene-F NanoCoated Coronary Stent System

2016

Abstract Objectives The aim of this study was to assess the safety and effectiveness of the COBRA Polyzene-F NanoCoated Coronary Stent System (CeloNova Biosciences, San Antonio, Texas) for the treatment of de novo coronary artery lesions. Background Polyzene-F–coated coronary stents have shown reduced thrombogenicity and inflammation in preclinical studies. Methods Patients with de novo coronary artery lesions meeting eligibility criteria were enrolled in a nonrandomized, prospective clinical trial. The primary endpoint was target vessel failure (TVF) (defined as a composite of cardiac death, myocardial infarction, or clinically driven target vessel revascularization) at 9 months. A pre-spe…

Diagnostic accuracy of 64-slice CT in the assessment of coronary stents

2007

PURPOSE: The purpose of this study was to assess the diagnostic accuracy of 64-slice computed tomography (64-CT) coronary angiography in the detection of coronary in-stent restenosis. MATERIALS AND METHODS: Ninety-five patients (72 men and 23 women, mean age 58+/-8 years) with previous percutaneous coronary intervention with stenting and suspected restenosis underwent 64-CT (Sensation 64, Siemens). The mean time between stent deployment and 64-CT was 6.1+/-4.2 months. The scan parameters were: slices 32 x 2, individual detector width 0.6 mm, rotation time 0.33 s, feed 3.84 mm/rotation, 120 kV, 900 mAs. After the intravenous administration of iodinated contrast material (Iomeprol 400 mgI/ml,…

Usefulness of multislice computed tomography to assess patency of coronary artery stents versus conventional coronary angiography

2008

BACKGROUND: The aim of the present study was to assess the in-stent restenosis and occlusion of coronary artery stents by multislice computed tomography (MSCT) compared with conventional coronary angiography in patients with atypical chest pain and not practicable/non-conclusive stress test. METHODS: Between December 2004 and March 2006, 81 patients were scheduled and of these 72 (65 men, mean age 61 years) with 90 stents underwent MSCT angiography using a 16-slice scanner, Toshiba Aquilion 16, 8-12 months after stent placement. RESULTS: Of the 90 stents, 71 (79%) could be assessed and 19 (21%) were excluded because the image quality at the stent level was incompatible with diagnostic asses…
