Introduction: Renal transplant recipients have a high peri-operative risk for cardiovascular events. The post-transplantation period also carries a risk of myocardial infarction (MI). Coronary artery disease (CAD) is a leading cause of death in these patients. We aimed to assess the risk of MI, the specific morbidity profile of MI after transplantation as well as the long-term prognosis after MI in renal transplantation (RT) patients regarding cardiovascular (CV) death and all-cause death. Methods: From a French national medical information database, all of the patients seen in French hospitals in 2013 with at least 5-years follow-up were retrospectively identified and patients without tran…

Clinical Syndromes, Pathogenesis, and Differential Diagnosis

1991

The temporal sequence of signs and symptoms in patients with cerebral ischemia provides important information for the analysis of underlying pathophysiologic mechanisms and in the search for a major hemodynamic or embolic cause. The signs reported and symptoms assessed are useful for localization of the ischemic region of the brain and identification of the affected vascular territories. Even in the case of a typical clinical picture the clinical findings alone are often insufficient for unequivocal anatomic and pathologic identification, however important they may be in the choice of diagnostic and therapeutic measures. In the first few hours after cerebral ischemia, determining the progno…

P864Histopathological damages in the epicardial coronary artery after ischemia and reperfusion injury in swine

2019

Abstract Background The microscopic consequences in the myocardial capillaries after myocardial infarction (MI) have been widely addressed, but little attention has been paid to epicardial coronary arteries. Since epicardial circulation is responsible for providing blood flow to the heart, understanding the microscopical changes on the epicardial artery after MI becomes also crucial. Purpose To evaluate the dynamics of the microscopic damages in the coronary arteries post-MI in swine model of reperfused MI. Methods MI was induced in swine by transient 90-min coronary occlusion of the left anterior descending (LAD) coronary artery using angioplasty balloons. One control group and four MI gro…

Radiologic Evaluation of the Transplant Candidate

2003

Before a patient is placed on the waiting list for liver transplantation, a variety of screening procedures are performed, including laboratory tests and radiological procedures. One goal is to search for abnormalities that preclude liver transplantation. Another is to detect abnormalities that in some way will affect the operative procedure. The individual periopera- tive risk is evaluated by searching for pulmonary, cardiac, and renal changes.

Effect of implantation technique on outcomes in patients receiving bioresorbable scaffolds in various clinical scenarios

2021

ABSTRACT Introduction and objectives: The PSP (pre-dilation, sizing and post-dilation) score, derived from the GHOST-EU registry, has evaluated the relationship between the implantation technique of bioresorbable scaffolds and the clinical outcomes. The objective was to perform an external validation of the PSP technique and to determine its effect on adverse cardiac events in various clinical and anatomical scenarios. Methods: Data from the REPARA registry (2230 patients) were used for external validation, whereas a common database combining REPARA and GHOST-EU (3250 patients) data was used to evaluate the effect of PSP technique in various clinical and anatomical scenarios. PSP-1 and PSP-…

0190: Predictive factors of intrahospital mortality in patients with right ventricular myocardial infarction

2016

IntroductionRight ventricular (RV) infarction is a serious and life threatening condition which mainly complicates an inferior wall myocardial infarction (MI). In the literature, data for predictive factors of mortality in this setting remains scarce.Aim to study predictive factors of intrahospital mortality in patients with RV infarction.Methods and resultsData was collected from a monocenter registry including all patients with AMI admitted in our department between January 1995 and March 2013. 1483 patients were enrolled in our registry. RV infarction was diagnosed in 160 (10.7%) patients, always complicating an inferior wall MI. 37 (23.1%) patients presented with right sided heart failu…

Safety and efficacy of endovascular treatment for carotid artery stenoses using proximal protection systems : 30-day follow-up

2017

Introduction. Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, carotid artery stenting (CAS) with use of proximal protection systems (PPS) plays an important role as alternative treatment modality, especially in high risk patients. This study was aimed at the assessment of safety of CAS with use of the PPS and also at identification of risk factors associated with this procedure. Material and methods. This was a post hoc analysis, with 30-day follow-up. We analysed results of treatment of 94 patients who underwent 97 CAS with PPS, 47 such procedures in asymptomatic, and 50 in symptomatic individuals. Results. There were 0 strokes during 30-day fo…

Porcine Model for Gluteal Artery Perforator Flap: Anatomy and Technique

2018

Although flap anatomy is well studied on cadavers and microsurgical techniques are well practiced on rats, still there are few training models for learning the techniques of perforator flap harvesting. The cadaver has no bloodstream, so accuracy of dissection cannot be evaluated and flap viability cannot be verified. Training on humans carries a high risk of flap damage. A living model for perforator flap harvest is needed to learn the technique before starting with its clinical application.

Sleep disordered breathing in patients with cardiovascular comorbidities hospitalized for pulmonary disease

2015

Sleep disordered breathing (SDB) is often overlooked in hospitalized patients. We screened consecutive patients with cardiovascular (CV) comorbidities hospitalized for respiratory problems to study SDB prevalence and type. Patients did not refer typical clinical signs of SDB. Patients (n=34, 21 M, mean age±SD 71±12 yr, BMI: 31.9±5.8 kg/m2) were studied by polygraphy (SomnoLab, Weinmann, Germany) 4.5±3.2 days after admission for COPD exacerbation (COPD-E, n=20), pleural effusion (n=2), asthma exacerbation (n=2) or other causes (n=10). On admission, 18 patients showed respiratory failure (RF, hypoxemic: n=9, hypercapnic: n=9). CV comorbidities (1.7±0.8/patient) were: hypertension (n= 27), hea…

Mechanism of reperfusion damage after thrombolysis and ‘direct PTCA’

1997

Summary There is general agreement between cardiologists, that reperfusion of the infarct related coronary artery (PTCA) is the method of choice for the treatment of an acute myocardial infarction. However, the method utilized for inducing a rapid and complete reperfusion is still discussed. Even if thrombolysis will remain the method of choice for the major part of the population, part of the patient cohort with acute infarction will be treated by direct PTCA. Rapid reperfusion of ischemic myocardium reduces infarct size by limiting infarct extension into the entire area at risk, although a reperfusion damage is induced in the core ischemic area. This reperfusion damage has been convincing…
