Prevalence of In-hospital Stroke Comparing MitraClip and Transcatheter Aortic Valve Implantation
Transcatheter aortic valve implantation (TAVI) and mitraclip (MC) are increasingly utilized for the treatment of aortic stenosis (AS) and mitral regurgitation (MR), respectively. Perioperative stroke is one of the most serious complications following TAVI given the valve calcification and possible embolization during valve implantation, and thus ongoing trials are assessing the use of embolic protection device following TAVI. On the other hand, no such trials are being conducted on MC as the evidence of stroke following MC is lacking and MC does not share the same etiology with TAVI 1.

Relation Between Stroke Volume Index to Risk of Death in Patients With Low-Gradient Severe Aortic Stenosis and Preserved Left Ventricular Function
The aim of the present study was to evaluate whether assessment of stroke volume index (SVI) can be used to improve risk stratification among patients with low-gradient severe aortic stenosis and preserved ejection fraction (EF). Study population comprised 409 patients with aortic valve area ≤1.00 cm2, mean gradient

Atrial Fibrillation, Stroke and Mortality Rates Following Transcatheter Aortic Valve Implantation
Transcatheter aortic valve implantation (TAVI) is considered a suitable treatment for patients with severe symptomatic aortic stenosis (AS) and high operative risk. Our aim was to evaluate the effect of pre-procedural and new-onset atrial fibrillation (NOAF) on mortality and stroke in patients undergoing TAVI. We performed a single center study of 380 consecutive patients enrolled to a TAVI registry. NOAF was defined as post-procedural atrial fibrillation (AF) occurring within 30 days following the procedure.

Meta-Analysis of the Prognostic Impact of Stroke Volume, Gradient and Ejection Fraction Following Transcatheter Aortic Valve Implantation
The prognostic implications of several baseline pre-procedural variables in patients with severe native valve aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) are unclear. The goal of this study was to determine the impact of reduced stroke volume index (SVI), low gradient (LG) and reduced ejection fraction (EF) on all-cause mortality. We searched MEDLINE, CENTRAL, EMBASE, Web of Science, and Scopus through 10/13/2014. We evaluated the association between low SVI (

Meta-Analysis of 5-Year Risk of All-Cause Death or Stroke After Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement
Transcatheter aortic valve implantation (TAVI) is an established alternative to surgical aortic valve replacement (SAVR) for patients with severe symptomatic aortic stenosis.1,2 Its indication has expanded from high-risk to include a low surgical risk younger population. Although the short-term results of TAVI and SAVR in patients with intermediate or high surgical risk are similar,1,2 outcomes beyond short-term periods remain unclear. Recently, the results of 5-year follow-up of the Surgical Replacement and Transcatheter Aortic Valve Implantation (SURTAVI) trial has been reported, which showed a similar rate of the compos...

Usefulness of the CHA2DS2-VASc Score to Predict Outcome in Patients Who Underwent Transcatheter Aortic Valve Implantation
Risk assessment for transcatheter aortic valve implantation (TAVI) patients remains challenging, especially in elderly and high-risk candidates. Although several risk factors contribute to increased morbidity and mortality after TAVI, simple risk scores for routine use are lacking. Applying the CHA2DS2-VASC (congestive heart failure, hypertension, age  ≥ 75 years, diabetes, prior stroke, vascular disease, age 65–74 years, sex [female] category) score as a novel risk stratification tool for conditions other than atrial fibrillation and stroke prevention has been previously examined; however, its usefulness in a popu...

Meta-Analysis of Cerebral Embolic Protection During Transcatheter Aortic Valve Replacement
Transcatheter aortic valve replacement (TAVR) has emerged as an effective therapy for patients with severe aortic stenosis, irrespective of surgical risks.1 Stroke due to cerebral embolization of debris is a devastating periprocedural complication of TAVR and is associated with poor outcomes. The risk of stroke could be decreased by capturing the debris using cerebral embolic protection (CEP) devices.2 An analysis of the TVT (Transcatheter Valve Therapy) Registry showed that CEPs were used in 28% of centers and 13% of all procedures.

Necropsy Findings Early After Transcatheter Aortic Valve Implantation for Aortic Stenosis
Although transcatheter aortic valve implantation has been available for 10 years, reports of cardiovascular morphologic studies after the procedure are virtually nonexistent. The investigators describe such findings in 2 patients, both 86 years of age, who died early (hours or several days) after transcatheter aortic valve implantation. Although the prosthesis in each was seated well, and each of the 3 calcified cusps of the native aortic valves was well compressed to the wall of the aorta, thus providing a good bioprosthetic orifice, the ostium of the dominant right coronary artery in each was obliterated by the native ri...

A Meta-Analysis of Mortality and Major Adverse Cardiovascular and Cerebrovascular Events Following Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement for Severe Aortic Stenosis
The purpose of this meta-analysis was to compare postprocedural mortality and major adverse cardiovascular and cerebrovascular events between transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) for severe aortic stenosis. Seventeen studies (n = 4,659) comparing TAVI (n = 2,267) and SAVR (n = 2,392) were included. End points were baseline logistic European System for Cardiac Operative Risk Evaluation score, all-cause mortality, cardiovascular mortality, myocardial infarction, stroke, transient ischemic attack, and major bleeding events. Mean differences or risk ratios with 95% conf...

Outcome of Transcatheter Aortic Valve Implantation in Patients With Low-Gradient Severe Aortic Stenosis and Preserved Left Ventricular Ejection Fraction
In conclusion, transcatheter aortic valve implantation appears to result in similar hemodynamic and long-term clinical outcomes for high-risk surgical patients with LGSAS as those with typical severe AS.
