Detection of Left Ventricular Thrombi on Cardiac Magnetic Resonance Viability Studies.

Objective: To highlight detection of left ventricular thrombi on cardiac magnetic resonance (CMR) viability studies.

Method: This retrospective observational study was conducted in the Radiology Department at our Hospital in Dhahran, from April 2015-2019. All recently re-perfused (post-percutaneous coronary intervention/PCI) patients with ST-segment elevation myocardial infarctions (STEMI), having low ejection fractions (<40%), impaired LV functions or abnormal wall motions on transthoracic echocardiographies (TTEs), who underwent cardiac magnetic resonance (CMR) imaging viability studies were included.

Removal of unusual multiple aortic valve fibroelastoma using right mini-thoracotomy.

Papillary Fibroelastomas are rare, primary cardiac tumors. They are typically diagnosed as an incidental finding but can also present as thrombo-embolic events. We present the case of 78-years- old man who presented to emergency room with a cerebrovascular event (CVE).

Prospective randomized trial of endoscopic vs open radial artery harvest for CABG: Clinical outcome, patient satisfaction, and midterm RA graft patency.

Background And Aim: Endoscopic radial artery (RA) harvest (ERAH) is an alternative to open RA harvest (ORAH) technique. Our aim was to ascertain clinical outcomes, patent satisfaction, and 1-year angiographic patency rates after ERAH and ORAH.

Patients And Methods: A total of 50 patients undergoing coronary artery bypass grafting were prospectively randomized to two groups.

Qualitative and quantitative assessment of smoking-related lung disease: effect of iterative reconstruction on low-dose computed tomographic examinations.

Purpose: The purpose of this research is to examine the role that differing levels of adaptive statistical iterative reconstruction (ASIR) have on the qualitative and quantitative assessment of smoking-related lung disease.

Materials And Methods: Institutional board review approval was obtained. A total of 52 patients undergoing clinically indicated low-dose computed tomographic (CT) examinations of the chest (100 kVp, 65 mAs, mean radiation dose 1.

Three-dimensional assessment of left atrial appendage orifice geometry and potential implications for device closure.

Transcatheter placement of left atrial closure device is an attractive therapy for patients with atrial fibrillation (AF), to avoid anticoagulation and reduce cerebrovascular events; however peri-device leaks occur. The geometry of the left atrial appendage (LAA) is not well understood, largely owing to limitations of 2-dimensional imaging techniques. We sought to better define the LAA orifice geometry, by performing 3-dimensional multi-detector computed tomography measurements.

Caseous calcification of the mitral annulus.

A 61-year-old asymptomatic woman was referred for echocardiography to evaluate recently detected systolic murmur. Transthoracic echocardiography revealed an echodense obstructive mass in the left ventricular outflow tract of unclear origin. Subsequent transesophageal echo suggested an intracardiac calcified tumor and recommended surgical excision.

Impact of post-implant SAPIEN XT geometry and position on conduction disturbances, hemodynamic performance, and paravalvular regurgitation.

Objectives: This report sought to study the impact of the balloon-expandable SAPIEN XT (Edwards Lifesciences, Irvine, California) transcatheter heart valve (THV) stent frame geometry and position on outcomes of transcatheter aortic valve replacement (TAVR).

Background: Post-implant THV geometry and position might impact atrioventricular conduction, hemodynamic performance, and annular sealing.

Methods: Eighty-nine consecutive patients who underwent TAVR with a Sapien XT THV had pre- and post-implant multidetector computed tomography, transthoracic echocardiography, and electrocardiograms performed to assess THV stent geometry, atrioventricular conduction, and hemodynamic performance.

Coronary artery imaging with single-source rapid kilovolt peak-switching dual-energy CT.

Purpose: To evaluate beam-hardening (BH) artifact reduction in coronary computed tomography (CT) angiography with dual-energy CT, to define the optimal monochromatic-energy levels for coronary and myocardial signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) in dual-energy CT, and to compare these levels with single-energy CT.

Materials And Methods: The study was approved by the institutional review board and/or ethics committee at each site. Patients provided informed consent.

Noninvasive fractional flow reserve derived from coronary computed tomography angiography: integrated anatomical and functional assessment.

Coronary computed tomographic angiography (CCTA) provides anatomic detail of lumen stenosis and information on plaque burden, plaque extent and plaque characteristics. CCTA does not, however, provide insight into the hemodynamic significance of a stenosis, which is essential to allow appropriate revascularization decision-making. This could reduce downstream invasive coronary angiography and nonbeneficial coronary revascularization, particularly with intermediate coronary stenosis.
