Effect of Transcatheter (via Femoral Artery) Aortic Valve Implantation on the Platelet Count and Its Consequences
In conclusion, a decrease in platelet count is a common phenomenon after TAVI, and its severity is associated with poor outcomes.

Transesophageal Echocardiography for Cardiac Thromboembolic Risk Assessment in Patients With Severe, Symptomatic Aortic Valve Stenosis Referred for Potential Transcatheter Aortic Valve Implantation
Stroke is a devastating complication after transcatheter aortic valve implantation (TAVI) and might partially be related to cardiac embolization. The aim of this single-center prospective study was to determine the incidence of intracardiac thrombi and left atrial spontaneous echo contrast (SEC), both known predictors of cardiac embolic stroke, in patients referred for potential TAVI. One hundred four consecutive patients with severe symptomatic aortic valve stenosis and at high or very high risk for surgery were included and underwent transesophageal echocardiography. In 11 patients (10.6%), intracardiac thrombi were dete...

Two-Year Outcomes for Patients With Severe Symptomatic Aortic Stenosis Treated With Transcatheter Aortic Valve Implantation
In conclusion, the clinical outcome of TAVI is favorable. The use of both procedural devices and multiple techniques in the same institution is feasible and potentially desirable.

Contribution of Three-Dimensional Transesophageal Echocardiography to Diagnosis and Management of Thrombosis of a St. Jude Mechanical Prosthesis in the Aortic Valve Position
Prosthetic valve thrombosis (PVT) is a serious complication after cardiac valve replacement and usually requires urgent management with either thrombolysis or surgery. A 38-year-old woman with history of ischemic stroke and multiple valvular surgeries including aortic St. Jude mechanical valve replacement (St. Jude Medical, St. Paul, Minnesota) presented with new-onset dyspnea on exertion. Transthoracic echocardiography and 2-dimensional transesophageal echocardiography (TEE) suggested an abnormally high gradient across the aortic valve () but could not determine the cause of the stenosis (, ). Three-dimensional (3D) TEE...
