Review Meta AnalysisAccuracy of transcranial Doppler for the diagnosis of intracardiac right-to-left shunt: a bivariate meta-analysis of prospective studies.
The aim of this meta-analysis was to determine the accuracy of transcranial Doppler (TCD) compared with transesophageal echocardiography (TEE) as the reference. ⋯ TCD is a reliable, noninvasive test with excellent diagnostic accuracies, making it a proficient test for detecting RLS. TCD can be used as a part of the stroke workup and for patients being considered for PFO closure. If knowledge of the precise anatomy is required, then TEE can be obtained before scheduling a patient for transcatheter PFO closure.

Review Meta AnalysisSurgical thresholds for bicuspid aortic valve associated aortopathy.
This systematic review seeks to present the outcomes of the natural history of aortopathy associated with bicuspid aortic valve (ABAV) and after interventions. ⋯ The risk associated with ABAV varies according to age and clinical setting. Nonetheless, despite aortic dilatation, the acute aortic event risk of ABAV appears low in current practice. Decision-making regarding the timing of intervention needs to be made on the basis of the balance between this low risk and both the morbidity and mortality of surgery.

Review Meta AnalysisPrognostic value of late gadolinium enhancement in clinical outcomes for hypertrophic cardiomyopathy.
The objective of this study was to perform a systematic review and meta-analysis of the predictive value of late gadolinium enhancement (LGE) cardiac magnetic resonance (CMR) for future cardiovascular events and death in hypertrophic cardiomyopathy (HCM). ⋯ Late gadolinium enhancement by CMR has prognostic value in predicting adverse cardiovascular events among HCM patients. There are significant relationships between LGE and cardiovascular mortality, heart failure death, and all-cause mortality in HCM. Additionally, LGE and SCD/aborted SCD displayed a trend toward significance. The assessment of LGE by CMR has the potential to provide important information to improve risk stratification in HCM in clinical practice.
