Researcher Nawar Ali Mohammed Al-Wather \u200e<\/strong>was awarded a PhD<\/strong> degree in Cardiology \u200e<\/strong>for her dissertation titled: The Predictive Value of D-Dimer Levels for Detecting Left Atrial Thrombus in Patients with Rheumatic Heart<\/em><\/strong>, which was submitted to the Department of Cardiology, Faculty of Medicine and Health Sciences \u2013 Sana\u2019a University. The dissertation defense was held on Thursday, August 27, 2026.<\/strong><\/h3>\n

The PhD Viva-Voce Committee, which was formed based on a resolution issued by the Graduate Studies and Scientific Research Council, consisted of the following:<\/h3>\n

    The dissertation aimed to evaluate the diagnostic accuracy of the D-dimer blood test as an independent biomarker for ruling out left atrial thrombus in patients with severe rheumatic mitral stenosis, and to provide a rapid and safe medical alternative that could reduce the need for transesophageal echocardiography (TEE). This could help expedite clinical decision-making, particularly given the limited availability and high cost of TEE.<\/h3>\n

    The study yielded several important findings, most notably identifying 360.6 ng\/mL as the optimal cutoff value for ruling out thrombus, achieving 100% accuracy in the study sample. By contrast, the conventional clinical cutoff of 500 ng\/mL was insufficient to rule out some cases, as it failed to detect 25% of active cases within the studied group.<\/h3>\n

    The statistical models also demonstrated that D-dimer testing is a strong and independent biomarker, while other factors, including atrial fibrillation and mitral valve area, did not provide additional diagnostic value beyond that obtained from D-dimer testing alone.<\/h3>\n

    Among patients whose results were not affected by anticoagulant medications, the study revealed a strong association between severe left atrial enlargement and elevated D-dimer levels. The mean left atrial diameter was 59.0 mm, reflecting the relationship between structural cardiac changes and the biological activity associated with thrombus formation.<\/h3>\n

    The researcher recommended incorporating D-dimer testing into the routine assessment of patients with rheumatic heart disease before percutaneous transvenous mitral commissurotomy (PTMC) or electrical cardioversion. This would help identify low-risk patients and reduce the need to wait for TEE.<\/h3>\n
