What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

Background: Transcatheter aortic valve replacement (TAVR) is a globally established therapy. However, there is significant variability in the antithrombotic management post-procedure. The data on antiplatetet and direct antithrombin agents suggest antiplatelet agents suffice. The degree of leaflet thickening on cardiac CT and the clinical implicati...
Background: In clinical practice, cardiac computed tomography (CCT) has a limited role in acute coronary syndromes (ACS). Several trials evaluated CCT in low and intermediate risk patients presenting to the emergency room (ER) and noted that it was both safe and feasible. During the COVID19 pandemic, it is imperative to adopt a pathway for the eval...
We demonstrate the utility of a printed 3-dimensional model to assist in the vascular access planning for a transcatheter aortic valve replacement in an elderly woman with complicated vascular anatomy including aortic coarctation, severe iliofemoral disease, and a small and tortuous left subclavian artery. (Level of Difficulty: Intermediate.)
ABSTRACT Accumulation of myocardial iron is the cause of heart failure and early death in most transfused thalassemia major patients. T2* cardiovascular magnetic resonance provides calibrated, reproducible measurements of myocardial iron. However, there is little data regarding myocardial iron loading and its relation to outcome across the world. A...

... Advances in 3-dimensional (3D) printing have proven its value and potential in many fields, in particular by opening up new approaches for the diagnosis and treatment of many complex cardiovascular diseases. Clinicians who specialize in diagnostic and interventional radiology could use imaging data to complete 3D reconstructions and models and to provide the surgeons with clear models of the individualized anatomical structures [6][7][8]. These clinicians collect the patients' preprocedural computed tomography angiography (CTA) imaging data to reconstruct 3D models and use the 3D printer to create individualized models [9,10]. ...

... They recommended further large regional prospective studies to better understand the baseline characteristics of CAD risk factors in middle eastern populations. 28 An earlier study in the Middle East by Dakik et al on the prevalence of CAC in 1154 asymptomatic men and women in Lebanon found that the mean CAC score as well as the percentiles increased consistently with age, except for those more than 74 years old. The CAC scores were higher in men than women in each age group, findings that suggest that the CAC score distribution in the Middle East is similar to published international data. ...

... [3, 13-16]. Liver iron concentration (LIC) values of > 7 and > 15 mg/g [dry weight] and cardiac T2* (cT2*) values of < 20 and < 10 ms have also been associated with cardiovascular disease and death in TDT [16][17][18][19][20][21][22][23]. Despite wide use of such thresholds, evidence mostly stems from very few, small, single-center, outdated (using liver biopsy for LIC), or short-term follow-up studies that often used pre-assigned thresholds; and they have been rarely revisited [24]. ...
