Exercise-Induced Sustained Ventricular Tachycardia without Structural Heart Disease: A Case Report
2020
Patient: Female, 51-year-old Final Diagnosis: Ventricular tachycardia Symptoms: Chest pain • shortness of breath Medication: — Clinical Procedure: Treadmill stress echocardiogram Specialty: Cardiology Objective: Unusual clinical course Background: Exercise-induced ventricular tachycardia (VT) has been widely reported in patients with preexisting structural heart disease or underlying ischemia and is attributed to reentry tachycardia and abnormal automaticity. However, studies regarding exercise-induced VT in individuals without evident structural heart disease are still limited. Case Report: A 51-year-old woman came to our practice for a treadmill stress echocardiogram. The patient experien…
Coronary chronic total occlusions and mortality in patients with ventricular tachyarrhythmias.
2020
Aims This study sought to assess the prognostic impact of coronary chronic total occlusions (CTO) in patients presenting with ventricular tachyarrhythmias on admission. Methods and results A large retrospective registry was used, including all consecutive patients presenting with ventricular tachyarrhythmias on admission and undergoing coronary angiography from 2002 to 2016. Patients with a CTO were compared with all other patients (non-CTO) for prognostic outcomes. Statistics comprised Kaplan-Meier and Cox regression analyses. Within a total of 1,461 consecutive patients included with ventricular tachyarrhythmias on admission, a CTO was present in 20%. At midterm follow-up of 18 months, th…
Clinical outcomes of patients with diabetes mellitus treated with Absorb bioresorbable vascular scaffolds: a subanalysis of the European Multicentre …
2017
Background Data on the clinical performance of bioresorbable scaffolds in patients with diabetes mellitus (DM) are still limited. The present study reported 1-year clinical outcomes associated with the use of everolimus-eluting bioresorbable vascular scaffolds (Absorb BVS; Abbott Vascular, Santa Clara, CA) in DM patients. Methods and Results This was a subanalysis from the GHOST-EU (Gauging coronary Healing with biOresorbable Scaffolding plaTforms in Europe) multicenter retrospective registry including patients treated with Absorb BVS between November 2011 and September 2014. In this study, a comparative analysis stratified according to DM was performed. The primary endpoint was target lesi…
Rational and design of the European randomized Optical Coherence Tomography Optimized Bifurcation Event Reduction Trial (OCTOBER)
2018
Background Percutaneous coronary intervention in complex bifurcation lesions is prone to suboptimal implantation results and is associated with increased risk of subsequent clinical events. Angiographic ambiguity is high during bifurcation stenting, but it is unknown if procedural guidance by intravascular optical coherence tomography (OCT) improves clinical outcome. Methods and design OCTOBER is a randomized, investigator-initiated, multicenter trial aimed to show superiority of OCT-guided stent implantation compared to standard angiographic-guided implantation in bifurcation lesions. The primary outcome measure is a 2-year composite end point of cardiac death, target lesion myocardial inf…
Introduction to coronary imaging with 64-slice computed tomography
2005
The aim of this article is to illustrate the main technical improvements in the last generation of 64-row CT scanners and the possible applications in coronary angiography. In particular, we describe the new physical components (X-ray tube-detectors system) and the general scan and reconstruction parameters. We then define the scan protocols for coronary angiography with the new generation of 64-row CT scanners to enable radiologists to perform a CT study on the basis of the diagnostic possibilities.
Risk Burden of Coronary Perforation in Chronic Total Occlusion Recanalization: Latin American CTO Registry Analysis
2022
Background Coronary perforation is a life‐threatening complication of acute percutaneous coronary intervention (PCI) for chronic total occlusions (CTO), but data on midterm outcomes are limited. Methods and Results Data from LATAM (Latin American)‐CTO Registry (57 centers; 9 countries) were analyzed. We assessed the risk of 30‐day, 1‐year major adverse cardiac events of coronary perforation using time‐to‐event and weighted composite end point analysis having CTO PCI without perforation as comparators. Additionally, we studied the independent predictors of perforation in these patients. Of 2054 patients who underwent CTO PCI between 2015 and 2018, the median Multicenter CTO Registry in Japa…
Routine Coronary Angiography is Still the Key Test for Patients Eligible for Lung Transplantation Also for Those With No Symptoms and With High Risk …
2022
Background. Coronary artery disease (CAD) has a considerable morbidity and mortality effect on the outcomes of a lung transplant. Currently, coronary angiography is performed as part of the pretransplant evaluation process. Unfortunately, there are no clear guidelines about performing cardiac angiography in lung transplant candidates. Background. The aim of our work is to find a correlation between cardiovascular risk and coronary arterial status to optimize the selection of patients for coronary angiography prior transplantation. Methods. We retrospectively analyzed 48 patients in whom coronary angiography and cardiac catheterization was performed during assessment for bilateral lung trans…
