Clinical presentation and short-term outcome of acute coronary syndrome in native young Saudi population.

Objectives: To investigate acute coronary syndromes (ACS) in the young Saudi population in Aseer Region, southwestern Saudi Arabia.

Materials And Methods: We retrospectively reviewed our database between January 2006 and May 2009, 924 patients were diagnosed to have ACS. Among them 107 patients (11.

Value of cardiac CT in comprehensive aortic valve and root evaluation before percutaneous aortic valve replacement.

Background: Aortic stenosis (AS) is the most frequent valvular heart disease, and patients who develop AS are at a high risk of sudden death. There is no medical cure available, and aortic valve replacement is the only effective treatment for advanced disease. Preoperative evaluation is the cornerstone of therapy and is necessary for selecting the implantation technique and valve.

Low radiation dose non-contrast cardiac CT: is it of value in the evaluation of mechanical aortic valve.

Background: Prosthetic bileaflet mechanical valve function has been traditionally evaluated using echocardiography and fluoroscopy. Multidetector computed tomography (MDCT) is a novel technique for cardiac evaluation.

Purpose: To evaluate bileaflet mechanical aortic valves using a low-milliampere (mA), non-contrast MDCT protocol with a limited scan range.

Usefulness of Tei index in patients with rheumatic mitral regurgitation and apparently normal left ventricular ejection fraction.

Background And Aim: Rheumatic mitral regurgitation is rather common in developing countries. It usually progresses insidiously, because the heart compensates for increasing regurgitant volume by left-atrial enlargement, causes left-ventricular overload and dysfunction, and yields poor outcome when it becomes severe. Doppler-echocardiographic methods can be used to quantify the severity of mitral regurgitation.
