Ventricular structural changes in patients with sleep-disordered breathing (SDB) and myocardial infarction
2018
Obstructive sleep apnea (OSA) is associated with cardiovascular diseases. Aim: To analyze structural parameters of myocardial damage in patients presenting with acute coronary syndrome (ACS) and its relationship with OSA severity. Method: This is a prospective, observational study in patients with a first acute myocardial infarction (MI) treated by percutaneous coronary intervention (PCI). Cardiovascular magnetic resonance (CMR) studies were performed at 3 days and 6 months. Eligible patients underwent a polysomnography within 30 days after PCI. Quantitative data were expressed as mean±SD. Linear regression analysis was used to describe associations between infarct characteristics and OSA. …
Assessment of no-reflow phenomenon by myocardial blush grade and pulsed wave tissue doppler imaging in patients with acute coronary syndrome
2014
Background: No-reflow phenomenon is a complication of myocardial revascularization and it is associated with a worse prognosis. Materials and Methods: A prospective study was carried out enrolling patients with acute myocardial infarction (64 patients, 49 male and 15 female, median age 64.9 ± 10.61 years), both STEMI and NSTEMI, who underwent myocardial revascularization with percutaneous coronary intervention (PCI). TIMI flow and Myocardial Blush Grade (MBG) were assessed at baseline (T0), in addition to tissue Doppler imaging (TDI) and electrocardiogram. Cardiological evaluation was also performed at T1 (one month after PCI) and T2 (every year after revascularization for a mean follow-up …

2021
[Purpose]: To characterize the global research trend in radiology departments based on bibliometric indicators.
Classification of coronary artery bifurcation lesions and treatments: time for a consensus
2008
Background: Percutaneous coronary intervention (PCI) of coronary bifurcation lesions remains a subject of debate. Many studies have been published in this setting. They are often small scale and display methodological flaws and other shortcomings such as inaccurate designation of lesions, heterogeneity, and inadequate description of techniques implemented. Methods: The aim is to propose a consensus established by the European Bifurcation Club (EBC), on the definition and classification of bifurcation lesions and treatments implemented with the purpose of allowing comparisons between techniques in various anatomical and clinical settings. Results: A bifurcation lesion is a coronary artery na…
Determining postoperative anterior chamber depth
2003
Abstract Purpose: To compare measured and calculated postoperative anterior chamber depths (ACDs). Setting: Department of Ophthalmology and Institute of Medical Physics, University of Vienna, Vienna, Austria, and Department of Ophthalmology, University of Mainz, Mainz, Germany. Methods: The postoperative ACD was measured in 189 pseudophakic eyes using a laboratory prototype of partial coherence interferometry (PCI). In 6 intraocular lens (IOL) groups, the mean ACD was calculated by ray tracing based on the best-known A-constants of the SRK formulas. In addition, for each IOL type, each measured ACD was compared with a value calculated using the individual spherical equivalent of the postope…
Routine cardiac troponin assessment after percutaneous coronary intervention
2019
: Although the angiographic and procedural success of percutaneous coronary intervention (PCI) is now very high, some severe complications may still develop, including periprocedural myocardial infarction (MI). An accurate diagnosis of this condition is essential for guiding the clinical management, as these patients may need a tailored management. The current recommendations for diagnosing periprocedural myocardial infarction based on the fourth universal definition appear at first sight straightforward, but the clinical and prognostic significance of routine periprocedural cardiac troponin (cTn) assessment remains uncertain. The current scientific evidence suggests that the likelihood of …
Dual lumen microcatheters for recanalisation of chronic total occlusions: A EuroCTO Club expert panel report
2021
Dual lumen microcatheters (DLMC) have become indispensable tools in the setting of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Other than allowing preservation and treatment of bifurcated coronary branches within or in the proximity of the CTO-body, they enable the use of modified parallel wiring, antegrade dissection and re-entry, collateral selection and retrograde negotiation of the distal CTO-cap. This Euro-CTO consensus document describes current DLMCs and suggests a practical guide to anatomies and techniques in which these devices are applicable.
Management of Coronary Artery Perforation
2020
Coronary artery perforation (CAP) is a rare but potentially life-threatening complication of percutaneous coronary intervention (PCI), however if recognized and managed promptly, its adverse consequences can be minimized. Risk factors for CAP include the use of advanced PCI technique (such as atherectomy and chronic total occlusion interventions) and treatment of severely calcified lesions. There are 3 major types of CAP depending on location: (a) large vessel perforation, (b) distal vessel perforation, and (c) collateral perforation. Large vessel perforation is usually treated with implantation of a covered stent, whereas distal and collateral vessel perforations are usually treated with c…
Dual-release hydrocortisone vs conventional glucocorticoids in adrenal insufficiency
2019
Background Dual-release hydrocortisone (DR-HC) improves metabolism in patients with adrenal insufficiency. The aims of this study were to compare the cardiovascular and metabolic effects of conventional glucocorticoids (GCs) vs. DR-HC and of high vs. low doses of GCs, after 48 months of observation. Methods We selected 27 patients on hydrocortisone (mean dose 17.5 ± 4.2 mg/day) and 20 patients on cortisone acetate (mean dose 37.5 ± 12.1 mg/day) who maintained this treatment (group A) and 53 patients switched to DR-HC (mean dose 22 ± 4.8 mg/day) (group B). At baseline and after 48 months, clinical and metabolic parameters and Framingham Risk Score (FRS) were obtained. Results After 48 month…
Imaging Assessment of Gastroduodenal Perforations.
2016
Gastroduodenal perforation is an emergency situation that usually requires early recognition and well-timed surgical treatment. It can arise from different natural, iatrogenic, or traumatic causes, and it can present with various symptoms especially in the early phase. This article reviews the role of the different imaging techniques in the diagnosis of gastroduodenal perforation, focusing on the direct and indirect signs that are encountered in conventional radiography and computed tomography; our personal experience is also provided.
