Long-Term Imaging and Clinical Outcomes of Surgical Left Atrial Appendage Occlusion With AtriClip
Surgical left atrial appendage (LAA) occlusion with an AtriClip (AtriCure, West Chester, Ohio) is frequently performed for stroke prophylaxis in patients with atrial fibrillation (AF). We conducted a retrospective analysis of all patients with long-standing persistent AF who underwent hybrid convergent ablation and LAA clipping. Contrast-enhanced cardiac computed tomography was performed at 3 to 6  months after LAA clipping to assess the degree of complete closure and the residual LAA stump. A total of 78 patients (64 ± 10 years, 72% male) underwent LAA clipping as part of hybrid convergent AF ablation, from 2019 to 2020.

Relation of Left Atrial Appendage Morphology Determined by Computed Tomography to Prior Stroke or to Increased Risk of Stroke in Patients With Atrial Fibrillation
This study aimed to assess inter-observer and intra-observer agreements in LAA morphology and its real value in stroke prediction. A total of 2264 atrial fibrillation (AF) patients who underwent computed tomography (CT) to explore the LAA anatomy were enrolled.

Usefulness of the MrWALLETS Scoring System to Predict First Diagnosed Atrial Fibrillation in Ischemic Stroke Patients
In this study we searched for echocardiographic parameters associated with first diagnosed AF, to form a scoring system for the identification of AF patients. We examined 571 ischemic stroke patients (72.7 ±13.5 years, 50.6% women), subdivided into 4 groups: documented cause without AF, first diagnosed AF, known paroxysmal AF, and permanent AF. All patients underwent transthoracic echocardiography, brain CT scan, carotid/vertebral ultrasound, and continuous ECG monitoring.

Psoas Muscle Area as a Predictor of Outcomes in Trans-Catheter Aortic Valve Implantation
Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty prior to surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution between 2011 2014. Preoperative computed tomography scans were used to measure PMA, which then was indexed to body surface area. Outcomes evaluated included: 1) early poor outcome (30 day mortality, stroke, dialysis, and prolonged ventilation), 2) one year mortality and 3) high reso...

Frailty is a powerful predictor of outcomes after transcatheter aortic valve implantation (TAVI). Sarcopenia as assessed by psoas muscle area (PMA) is a validated tool to assess frailty before surgical procedures. We evaluated PMA as a predictor of outcomes after TAVI in 152 consecutive patients who underwent this procedure at our institution from 2011 to 2014. Preoperative computed tomography scans were used to measure PMA, which then was indexed to body surface area. Outcomes evaluated included (1) early poor outcome (30  days mortality, stroke, dialysis, and prolonged ventilation), (2) 1-year mortality, and (3) high-re...

PP-096 A Newly Defined CHA2DS2-VASc-CAC Score and Using Prediction of Coronary Artery Disease Severity by Computed Tomography
CHA2DS2-VASc scores are validated tools for assessing stroke risk in patients with atrial fibrillation (AF). It is known that traditional risk factors for coronary artery disease and CHAD2 VASc score's parameters are similar.We formulated the CHA2DS2-VASc-CAC score comprising coronary calcium score(CACS) in addition to the components of the CHA2DS2-VASc score and male instead of female gender as We evaluated multivariable risk assessment tools to identify those at high risk of severe CAD in patients who underwent computed tomography(CT).

Coronary Artery Calcium and Risk of Atrial Fibrillation (From the Multi-Ethnic Study of Atherosclerosis)
Calcified coronary arteries are associated with the development of cardiovascular disease and stroke. It is currently unknown whether coronary artery calcium (CAC) is associated with an increased risk of atrial fibrillation (AF). We addressed this question in 6,641 participants (mean age 62 ± 10; 53% women; 62% non-whites) from the Multi-Ethnic Study of Atherosclerosis (MESA) who were free of baseline clinical cardiovascular disease and AF. CAC measurements were assessed by cardiac computed tomography (CT) at study baseline.

Impact of Co-morbidity on the Risk of First-Time Myocardial Infarction, Stroke, or Death After Single-Photon Emission Computed Tomography Myocardial Perfusion Imaging
In conclusion, independently of co-morbidity level, an abnormal SPECT MPI scan was associated with an increased 10-year risk of myocardial infarction and all-cause death but not stroke.

Meta-Analysis of Global Left Ventricular Function Comparing Multidetector Computed Tomography With Cardiac Magnetic Resonance Imaging
We compare the diagnostic accuracy of multidetector row computed tomography (MDCT) to cardiac magnetic resonance imaging (CMR) for evaluating global left ventricular function. We systematically searched PubMed, CINAHL, Cochrane CENTRAL, Scopus, and the Web of Science databases for studies published between 1966 to January 2013 that compared left ventricle (LV) volumes, ejection fraction (EF) and LV mass measured by MDCT and CMR. We performed meta-analyses and used random-effects model with inverse variance weighting test to determine the overall bias and limits of agreement of LV end-diastolic volume, end-systolic volume, ...
