Multicenter Evaluation of Transcatheter Aortic Valve Replacement Using either SAPIEN XT or CoreValve: Degree of Device Oversizing by Computed‐Tomography and Clinical Outcomes
Conclusions: Optimal clinical performance of CoreValve and SAPIEN XT appears to be reached with different degrees of oversizing. Certain annular sizes that allow for only moderate or large oversizing, but not both, appear to benefit from a device specific approach. This article is protected by copyright. All rights reserved.

Outcomes and predictors of mortality after transcatheter aortic valve implantation: Results of the Brazilian registry
Conclusion: This multicenter registry reflected a real‐life national TAVI experience. Comorbidities, periprocedural complications and moderate/severe PVR were associated with increased mortality and the use of TEE to monitor the procedure acted as a protective factor.

Transcatheter aortic valve implantation using the left transcarotid approach in patients with previous ipsilateral carotid endarterectomy
Conclusions. TAVI through a left transcarotid approach in patients previously operated on for ipsilateral CEA is feasible and safe. The presence of a previous ipsilateral CEA represents no more a limitation to the utilization of this promising access route. At short‐term follow‐up, mortality and major complications rates are low.

The Flatstent versus the conventional umbrella devices in the percutaneous closure of patent foramen ovale
Conclusion: No difference was found in closure or complication rates between the Flatstent and the umbrella devices. With appropriate pre‐assessment of the PFO anatomy, the Flatstent works as a safe and effective method of treating the PFO from within the tunnel, especially in those with long tunnel PFOs. Longer follow up is needed to establish superiority. This article is protected by copyright. All rights reserved.

Predictors of outcomes following catheter‐based therapy for acute stroke
Conclusion Successful revascularization with CBT leads to a good neurologic outcome in selected stroke patients. Medical co‐morbidities and increased age >65y contributed to poor outcomes. To support broadening the number of physicians qualified to perform catheter‐based stroke interventions, this study demonstrates that Interventional Cardiologists participating on a stroke team achieve comparable outcomes to Neurointerventionalists.

PFO closure with only fluoroscopic guidance: 7 years real world single centre experience
Conclusions. In our experience Fluoro‐G PFO closure was performed mainly in cases of simple anatomy, with similar results in terms of safety and efficacy compared to Echo‐G cases. Both fluoroscopy and total procedural times were lower in the Fluo‐G cases. © 2014 Wiley Periodicals, Inc.

Transseptal puncture to facilitate device closure of “long‐tunnel” patent foramen ovale
Conclusion Though not without risk, transseptal puncture can be a valuable tool for facilitating device closure of long‐tunnel type PFOs. GORE® HELEX® Septal Occluder may be an effective option for facilitating device closure for patients with long‐tunnel type PFO. © 2014 Wiley Periodicals, Inc.

Influence of percutaneous mitral valve repair using the MitraClip® system on renal function in patients with severe mitral regurgitation
Conclusion: Successful PMVR was associated with an improvement in renal function. The improvement in renal function was associated with the extent of MR reduction and pre‐existing kidney dysfunction. Our data emphasize the relevance of PVMR to stabilize the cardiorenal axis in patients with severe mitral regurgitation. © 2014 Wiley Periodicals, Inc.

Neuroimaging patterns of ischemic stroke after percutaneous coronary intervention
Conclusions The vast majority of radiologically‐confirmed ischemic strokes related to PCI are embolic. MCA territory strokes are most common and uniformly fatal when the entire MCA territory is affected. Functional outcomes in survivors of PCI‐stroke are improved when only a single arterial territory is affected. © 2014 Wiley Periodicals, Inc.

Cardiac CT and echocardiographic evaluation of peri‐device flow after percutaneous left atrial appendage closure using the AMPLATZER cardiac plug device
Conclusion: The present study evaluates for the first time peri‐device flow after LAA closure by ACP using a combined cardiac‐CT and TEE follow‐up. Persistent LAA‐perfusion was frequently detected, leak‐sizes were small and were less frequent when lobe compression was >10% and lobe orientation was perpendicular to the LAA‐neck axis, that was also related to the LAA anatomy. The clinical significance of these small leaks after LAA‐closure using ACP needs to be further evaluated in future studies. © 2014 Wiley Periodicals, Inc.

Incidence and timing of hypotension after transcervical carotid artery stenting
ConclusionsMost postoperative hypotension episodes occurred within the first 6 hr, and more than one‐third between the 6 and 12 hr post‐procedure. All patients with late hypotension were asymptomatic. There was no difference in complications between the study groups. In patients undergoing ambulatory CAS, hemodynamic monitoring in the postoperative period is particularly important during the first 12 hr. © 2014 Wiley Periodicals, Inc.
