CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Advances in Interventional Cardiology. Management of Antiplatelet and Anticoagulant Therapy in Patients With Atrial Fibrillation in the Setting of Acute Coronary Syndromes or Percutaneous Coronary Interventions

Davide Capodanno, MD, PhD and Dominick J. Angiolillo, MD, PhD

Introduction: Atrial fibrillation (AF), the most common cardiac arrhythmia, occurs in 1% to 2% of the general population, with a prevalence varying from 0.5% in subjects 40 to 50 years old to 5% to 15% in the elderly who are >80 years old.1–3 Stroke is the most feared complication of AF, resulting in death or disabling symptoms in a vast proportion of cases.4 In the Framingham study, the age-adjusted incidence of stroke was 5-fold higher in subjects with AF, and the attributable risk raised from 1.5% at 50 to 59 years to 23.5% at 80 to 89 years.5

CIRCULATION: CARDIOVASCULAR INTERVENTIONS. Images and Case Reports in Interventional Cardiology. Successful Endovascular Stroke Rescue With Retrieval of an Embolized Calcium Fragment After Transcatheter Aortic Valve Replacement

Introduction: A 90-year-old symptomatic woman with a critical aortic stenosis was referred for transcatheter aortic valve replacement (TAVR). The procedure was performed under locoregional anesthesia from a right femoral approach, with the successful implantation of a 23-mm CoreValve (Medtronic Inc, Minneapolis, MN). Echocardiographic assessment after TAVR showed a mean transprosthetic gradient of 16 mm Hg and trace paravalvular regurgitation. After percutaneous closure of the right femoral artery, the patient suddenly became unresponsive. After prompt intubation, emergency cerebral MRI was performed to assess the presence of reversible ischemia and exclude parenchymal hemorrhage, showing partial occlusion of the right middle cerebral artery with ischemia in the corresponding territory (Figure 1). Conventional cerebral angiography confirmed partial M1-M2 occlusion of the right middle cerebral artery (Figure 2A; Movie I in the Data Supplement). Complete revascularization was achieved using a 4.0×20 mm Solitaire FR retrievable stent (ev3, Irvine, CA) with capture of the embolic material (Figure 2B; Movies II and III in the Data Supplement). The onset-to- reperfusion delay was 150 minutes.

JACC: CARDIOVASCULAR INTERVENTIONS. Comparison of Medtronic CoreValve and Edwards Sapien XT for Transcatheter Aortic Valve Implantation. The Need for an Imaging-Based Personalized Approach in Device Selection

Javaid Iqbal, PhD†; Patrick W. Serruys, MD, PhD†

Transcatheter aortic valve implantation (TAVI) has revolutionized the treatment of symptomatic severe aortic stenosis in patients at a high risk of surgical valve replacement 1. The 2 main devices in clinical use at present are the self-expandable Medtronic CoreValve (MCV) (Medtronic, Minneapolis, Minnesota) and balloon-expandable Edwards SAPIEN XT valve (ESV) (Edwards Lifesciences, Irvine, California). Paravalvular aortic regurgitation (AR) is not an uncommon complication after TAVI, and suboptimal device sizing and positioning are the main culprits (2).
