Cardiac imaging in ischemic stroke or transient ischemic attack of undetermined cause: Systematic review & meta-analysis
Patients with ischemic stroke or transient ischemic attack (TIA) of undetermined cause often undergo cardiac imaging in search of a cardioembolic source. As the choice of the most appropriate imaging approach is controversial and therapeutic implications have changed over time, we aimed to identify in patients with “cryptogenic stroke or TIA” the yield of transthoracic or transesophageal echocardiography (TTE or TEE) and cardiac computed tomography (CT).

Preoperative CT scan for postoperative stroke prediction in minimally invasive mitral valve surgery: Statistical concern for clinical factors in regression analyses
We read with great interest the paper by Leonard et al. [1] online published in IJC in Dec 12, 2018. They included 57 articles (19 CT versus 38 non-CT) with a total of 13,731 patients in the pooled analysis, and tried to identify the potential influential clinical factors of stroke occurrence following minimally invasive mitral valve surgery (MIMVS). Finally, 10 clinical factors (age, female gender, CAD, hypertension, non-CT screening, etc.) have been found to be with significant importance for the incidence of stroke using univariate mete-regression analyses.

Systematic preoperative CT scan is associated with reduced risk of stroke in minimally invasive mitral valve surgery: A meta-analysis
Minimally invasive mitral valve surgery (MIMVS) is performed with increasing frequency. However, patients undergoing MIMVS might be at increased risk of perioperative stroke, mainly due to retrograde aortic embolization during femoral cardio-pulmonary bypass. Pre-operative computed tomography (CT) screening allows visualization of the aorta and femoro-iliac vessels and individualization of the surgical approach. In this meta-analysis, we aim to determine if systematic pre-operative CT screening is associated with decreased incidence of post-operative stroke and other complications following MIMVS.

Impact of stroke volume assessment by integrating multi-detector computed tomography and Doppler data on the classification of aortic stenosis
The prevalence of low flow low gradient (LFLG) severe aortic stenosis (AS) may be overrated due to underestimation of stroke volume in two-dimensional (2D) echocardiography. The implications of 3D imaging on stroke volume calculation for AS classification have not been elucidated. Integrating multi-detector computed tomography (MDCT) and Doppler data may improve diagnostic accuracy in patients with LFLG AS.

Relationship between left atrial appendage morphology and thrombus formation in patients with atrial fibrillation
Atrial fibrillation (AF) is the most common chronic arrhythmia seen in clinical practice and is associated with increased risk of systemic thromboembolism. However, scoring systems such as CHADS2 score and CHA2DS2VASc score for assessing stroke risk were still plagued with limitations [1,2]. About 90% of the thrombus was detected in left atrial appendage (LAA) [3], which can be identified by transoesophageal echocardiography (TEE), an invasive test with some risk of complications [4]. Computed tomography (CT), on the other hand, is non-invasive and may provide more details about the morphology of the LAA [5].

Current clinical practice of transesophageal echocardiography and cardiac computed tomography prior to atrial fibrillation ablation in Canada
Pulmonary vein isolation (PVI) is the procedure of choice in patients with symptomatic atrial fibrillation (AF) who failed antiarrhythmic drugs [1]. Preprocedurally, cardiac computed tomography (CCT) is required to define the left atrium (LA) and the pulmonary veins (PV) on which to superimpose an electrical map [1]. Patients also routinely undergo transesophageal echocardiography (TEE) to rule out the presence of LA/left atrial appendage (LAA) thrombus, which is an absolute contraindication to the procedure due to the increased risk of stroke [1].

Predictive Value of Coronary Blood Flow for Future Cardiovascular Events in Patients with Atrial Fibrillation
Atrial fibrillation (AF) is associated with impaired coronary flow and diminished myocardial perfusion [1–3]. In a previous study, we demonstrated that patients with AF in the absence of obstructive coronary artery disease (CAD) have significantly higher Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) for all three coronary vessels compared to the control subjects without AF [1]. However, the clinical importance of the increased TFC in AF patients has not been fully elucidated, although TFC seems to be independently associated with mean platelet volume [4], an independent risk factor for future stroke and ...

Association of computed tomography-derived left atrial size with major cardiovascular events in the general population: The Heinz Nixdorf Recall Study
Conclusion: LA size is associated with incident major CV events independent of risk factors and CAC-score. Once cardiac CT imaging is performed, assessment of LA size may complement information of this imaging modality.Highlights:

Routine preprocedural transesophageal echocardiography might not be necessary for stroke prevention evaluation in AF patients on anticoagulation therapy
Conclusion: The overall periprocedural stroke rate was low (0.3%) in AF patients on anticoagulation therapy. The preprocedural MDCT detected all patients with the LA thrombus. In AF patients with low CHADS2 score, optimal anticoagulation and relatively preserved left ventricular ejection fraction, routine preprocedural TEE in addition to the MDCT might not be necessary to decrease the periprocedural stroke rate.

Aortic valve calcium score as a predictor for outcome after TAVI using the CoreValve revalving system
Abstract: Background: TAVI is a novel treatment option for patients at too high risk for surgery. Risk scores for surgical valve replacement failed to accurately predict outcomes after TAVI and alternative risk parameters are lacking so far.Objective: We evaluated the CT-derived aortic valve calcification score as a predictor for outcome during and after TAVI.Methods: Transfemoral TAVI using the CoreValve device was performed in 68 patients, in whom the aortic valve calcium score was determined from preprocedural 64-sclice ECG gated CT-scans.Results: 30-day MACE rate (death, stroke, MI) was 10.3%, 1-year mortality was 11.8...
