Mechanical thrombectomy using the Solitaire stent in a left main coronary artery: A novel approach to coronary thrombus retrieval
The Solitaire stent is a self‐expanding nitinol, fully retrievable stent that was originally designed for applications in cerebral circulation. Expanded indications for its use in mechanical embolectomy during acute ischemic stroke have proven safe and effective. Herein, we describe a novel use of this stent to perform a mechanical thrombectomy of a large left main coronary artery thrombus. © 2016 Wiley Periodicals, Inc.

Sex‐related differences in outcomes among men and women under 55 years of age with acute coronary syndrome undergoing percutaneous coronary intervention: Results from the PROMETHEUS Study
Conclusion: Women younger than 55 years of age undergoing ACS PCI have significantly greater comorbidities than young men. Despite a higher risk clinical phenotype in women, prasugrel use was significantly lower in women than men. Female sex was associated with a significantly higher risk of 1‐year MACE and bleeding than men, findings that are attributable to baseline differences. This article is protected by copyright.

Asymptomatic migration of an AMPLATZER ™ Amulet™ left atrial appendage occluder through the mitral valve
An 84‐year‐old woman with a history of hemorrhagic stroke was admitted for a new cerebral ischemic event. While in hospital, she was diagnosed with paroxysmal atrial fibrillation. Owing to her high thromboembolic risk (CHA2DS2‐VASc score of 6) we performed left atrial appendage (LAA) closure using a 22‐mm AMPLATZER™ Amulet™. The procedure was successful. Systematic follow‐up with transthoracic echocardiography 8 hr later revealed that the LAA occluder had migrated and become entrapped in the mitral subvalvular apparatus. At this time, the patient was asymptomatic. The device was recovered percutaneously using...

Comparison of transradial coronary procedures via right radial versus left radial artery approach: A meta‐analysis
ConclusionOur meta‐analysis suggests a small but statistically significant difference in terms of contrast use and fluoroscopy time in favor of coronary procedures performed via left radial approach in comparison to right radial approach without any significant difference in access site or other procedural complications between the two radial approaches. © 2016 Wiley Periodicals, Inc.

Long ‐term follow‐up after PFO device closure
ConclusionsDevice closure of PFO can be performed safely with very good long‐term resolution of atrial shunting. Recurrent neurologic events after PFO closure may reflect additional comorbid risk factors unrelated to the potential for paradoxical embolism. © 2016 Wiley Periodicals, Inc.

Our aspirations still disappoint
Key Points Routine thrombectomy during coronary intervention for STEMI is not supported by two large prospective randomized trials. Occasional case‐specific clot removal, while appealing, remains an unproven adjunct to primary stenting during STEMI therapy. While early MACE events may be lower, during follow‐up, there is a higher risk of stroke in patients who undergo thrombectomy.

Life in the left atrial appendage fast lane after FDA approval: Moving forward on new technology at last
Key Points FDA approval of the WATCHMAN is expected to spur development and availability of a range of evolutionary and revolutionary technologies for left atrial appendage occlusion. The fourth generation WATCHMAN described in this article has multiple features that will potentially streamline the deployment process and have the potential to make left atrial appendage occlusion safer. The population studied was too small to compare the relatively high adverse event rate with the known outcomes associated with existing WATCHMAN technology. Going forward, in part because of improvements in technology, it is likely that lat...

The outcomes of transcatheter aortic valve replacement in a cohort of patients with end‐stage renal disease
ConclusionsPatients with ESRD who undergo TAVR are at high risk for mortality and complications. TAVR outcomes are comparable to but not substantially better than those with SAVR. Transfemoral TAVR seems to be at least as safe and effective as the current standard SAVR in patients undergoing aortic valve replacement. © 2016 Wiley Periodicals, Inc.

Efficacy and safety of transcatheter aortic valve replacement in intermediate surgical risk patients: A systematic review and meta‐analysis
ConclusionsIn this meta‐analysis we found that TAVR may be an acceptable alternative to SAVR in patients with intermediate risk for surgery. However, we must await evidence from the current large randomized trials before widespread adoption of this procedure is undertaken. © 2016 Wiley Periodicals, Inc.

Double cerebral embolic protection: Is more less?
Key Points During carotid artery stenting (CAS), atheroemboli may arise from the aorta, arch, and ipsilateral carotid artery. Embolic protection devices (EPD) are designed to decrease the risk of stroke resulting from atheroembolization from the ipsilateral carotid artery during CAS; double (proximal and distal) EPDs may decrease the risk of stroke in high‐risk patients and lesions. Further studies are needed to determine if double EPDs are superior to single EPDs or other devices.
