Cardioembolic Stroke: Mechanisms and Therapeutics

Semin Neurol 2017; 37: 326-338 DOI: 10.1055/s-0037-1603465Cardioembolic stroke accounts for nearly 30% of all known stroke mechanisms. This percentage may be underestimated, however, when considering the large proportion of cryptogenic strokes that likely have a covert cardiac source. Although it is well known that cardioembolic stroke can occur in the setting of atrial fibrillation, other mechanisms such as a systolic heart failure, patent foramen ovale, valvular dysfunction, and aortic arch atheroma are commonly encountered in daily practice. The authors provide an overview on the epidemiology, pathogenesis, diagnostic evaluation, and secondary prevention treatment strategies for cardioembolic stroke.

Authors: Asano M, Hayakawa T, Kato Y, Kawada K, Goto S, Branch J, Shimizu H Abstract A 72-year-old lady with atrial fibrillation and chronic renal failure was hospitalized due to bradycardic shock with electrocardiographic QRS prolongation. She had experienced limb shaking two days before hospitalization, and additionally developed hallucinations one day before admission. Pilsicainide intoxication was diagnosed from a review of her medications and electrocardiographic findings. Consequently, continuous hemodiafiltration was performed resulting in a resolution of the hallucinations and the QRS prolongation. This is ...

Strokes remain a leading cause of morbidity and mortality in patients with ventricular assist devices (VADs). Varying study populations, event definitions, and reporting methods make direct comparison of neurologic event risk across clinical trials and registries challenging. We aim to highlight important differences among major VAD studies and standardize rates of neurologic events to facilitate a comprehensive and objective comparison. We systematically identified and analyzed key clinical trials and registries evaluating the HeartMate II (HMII), HeartMate 3 (HM3), and HVAD devices. Reported neurologic events were nonexc...

Dysfunction of different components within continuous-flow (CF) left ventricular assist device (LVAD) systems may cause adverse cardiovascular and end-organ sequelae. Outflow graft obstruction is a recognized type of LVAD component dysfunction. Ten patients were admitted and treated for LVAD outflow graft obstruction. Two of these patients subsequently developed recurrent outflow graft obstruction requiring reintervention; however, each reoccurrence was at a different site than the original obstruction. Thus, a total of 12 cases of obstruction were analyzed. The most common reasons for hospital admission were low flow LVAD...

Ventricular assist devices (VADs) are an increasingly common therapy for end-stage heart failure across all ages as a bridge to recovery or transplant and more recently as destination therapy. With increasing experience and difficulties with establishing therapeutic heparin levels, we have begun to explore the effectiveness of direct thrombin inhibitors in this patient population. This is a retrospective review of all long-term VAD patients, both adult and pediatric, who were anticoagulated with bivalirudin between January 2009 and January 2016. The starting dose was 0.3 mg/kg/hr, and dose was titrated for a goal pa...

We present three cases that developed moderate to severe AI while on HeartMate II (Abbott Laboratories, Chicago, IL) LVAD support; hence, TAVR procedure was performed. Patients A and B (74 year old and 38 year old) developed severe AI and patient C (67 year old) developed moderate AI with cardiogenic shock, after 368, 1,288, and 342 days on LVAD support, respectively. Their aortic valve annulus sizes were 24.2, 24.6, and 23.3 mm, respectively. Oversized Edwards SAPIEN 3 valves (Edwards, Lifesciences, Irvine, CA) were implanted via a transfemoral approach. The patients were hemodynamically stable after the procedure ...

Conclusion An occult preexisting atrial fibrillation may lead to unnecessary percutaneous foramen ovale closure in a significant proportion of patients. A 6-month loop-recorder monitoring may improve the patient oriented decision-making.

Conclusions The risk of developing ischemic stroke was almost 11 times higher in young patients with CHD than in the general population, although absolute risk is low. Cardiovascular comorbidities were strongly associated with the development of ischemic stroke in young CHD patients.
