Recent Nationwide Trends in Transcranial Doppler Utilization During Acute Ischemic Stroke Hospitalizations (P4.296)
Conclusions:Over the last decade there has been a slight but steady decrease in the use of TCD during AIS hospitalizations in the US. Future studies should examine the cost-utility of TCD, especially with the advent of endovascular stroke treatment systems.Disclosure: Dr. Liu has nothing to disclose.

Stroke volume ratio derived from magnetic resonance imaging as an indicator of interventricular dyssynchrony predicts future cardiac event in patients with biventricular Fontan circulation
This study wanted to assess the hypothesis that interventricular dyssynchrony evaluated by cardiac magnetic resonance imaging (MRI) can predict future cardiac events in patients with biventricular heart who have undergone Fontan surgery. We prospectively enrolled consecutive patients with biventricular Fontan circulation from 2003 to 2016, and performed protocolized cardiac MRI. We determined the stroke volume ratio (SVr) using the following formula to assess interventricular dyssynchrony: (stroke volume (SV) of the two whole ventricles)/(SV of the right ventricle  + SV of the left ventricle), by tracing cine MRI data....

Early Wallerian degeneration in a neonate with MCA stroke
A 23-day-old female with history of transposition of great arteries, ventricular septal defect, pulmonary stenosis and placement of right modified Blalock-Taussig shunt complicated by thrombosis at age 9 days of life presented with episodes of upper extremity extension and gasping respirations concerning for seizure. Brain MRI demonstrated an extensive, acute right middle carotid artery (MCA) territory stroke with occlusion of the right proximal MCA. There was also a small left frontal stroke. Diffusion restriction abnormalities with simultaneous presence of hyperintensity on T2 sequences in the cotricospinal tract consist...

Early Wallerian Degeneration in a Neonate With Middle Carotid Artery Stroke
A 23-day-old girl with a history of transposition of the great arteries, ventricular septal defect, pulmonary stenosis, and placement of right modified Blalock-Taussig shunt complicated by thrombosis at age 9 days of life presented with episodes of upper extremity extension and gasping respirations concerning for seizure. Brain magnetic resonance imaging demonstrated an extensive, acute right middle carotid artery territory stroke with occlusion of the right proximal middle carotid artery. There was also a small left frontal stroke.

Case Report: Α Case of Endocarditis and Embolic Stroke in a Child, Suggestive of Acute Q Fever Infection.
Abstract Acute Q fever is usually asymptomatic or is associated with a mild self-limited course and a favorable outcome. The occurrence of endocarditis during acute infection by Coxiella burnetii is an emerging clinical entity observed in adults that has been attributed to an autoimmune complication of early infection. Herein, we report the first case of a previously healthy 2-year-old child with endocarditis complicated by septic embolic stroke, in which the identified microbiological evidence was suggestive of acute rather than chronic C. burnetii infection. The development of endocarditis in this case occurred ...

Multiple Stroke Syndrome Caused by Air Embolism Following Removal of a Central Venous Catheter.
Abstract The removal of a central venous catheter on a ward leads to a paradox air embolism in a 53-year-old male patient with an unknown ventricular septal defect. The patient undergoes sufficient cardiopulmonary resuscitation but suffers from a multiple stroke syndrome with serious neurological deficits. PMID: 33053590 [PubMed - indexed for MEDLINE]

Quantification of the area and shunt volume of multiple, circular, and noncircular ventricular septal defects: A 2D/3D echocardiography comparison and real time 3D color Doppler feasibility determination study
ConclusionsThree‐dimensional echocardiography (3DE) is a feasible method for determining VSD area and is more accurate than 2DE for evaluating the area of multiple or noncircular VSDs. Real‐time 3D color Doppler echocardiography (RT3D‐CDE) is a feasible method for quantifying the shunt volume of multiple or noncircular VSDs.

Major adverse cardiovascular events in adult congenital heart disease: a population-based follow-up study from Taiwan
Conclusions: After a median of 11 years of follow-up, the Taiwanese patients with ConHD were at an increased risk of life-long cardiovascular MACE, including heart failure, stroke, acute coronary syndrome, and malignant dysrhythmia. Surgical correction may help to decrease long-term MACE in ConHD patients, especially those with ASD.

Quantification of Shunt Volume Through Ventricular Septal Defect by Real-Time 3-D Color Doppler Echocardiography: An Study
Quantification of shunt volume is important for ventricular septal defects (VSDs). The aim of the in vitro study described here was to test the feasibility of using real-time 3-D color Doppler echocardiography (RT3-D-CDE) to quantify shunt volume through a modeled VSD. Eight porcine heart phantoms with VSDs ranging in diameter from 3 to 25 mm were studied. Each phantom was passively driven at five different stroke volumes from 30 to 70 mL and two stroke rates, 60 and 120 strokes/min. RT3-D-CDE full volumes were obtained at color Doppler volume rates of 15, 20 and 27 volumes/s.

Human Fetal Hearts with Tetralogy of Fallot have Altered Fluid Dynamics and Forces.
In this study, we performed patient-specific ultrasound-based flow simulations of 3 TOF and 7 normal human fetal hearts. TOF right ventricles (RV) had smaller end-diastolic volumes (EDV) but similar stroke volumes (SV), while TOF left ventricles (LV) had similar EDV but slightly increased SV compared to normal ventricles. Simulation showed that TOF ventricles had elevated systolic intra-ventricular pressure gradient (IVPG), and required additional energy for ejection, but IVPG elevations were considered to be mild relative to arterial pressure. TOF RV and LV had similar pressures due to equalization via ventricular septal ...
