Term
Best Echo view for (Subvalvular) Discrete Membranous Stenosis
Definition
PLAX, Apicals
Term
Best Echo view for (Valvular) Bicuspid Aortic Valve
Definition
PSAX (allows visualization of the number of cusps) and PLAX (ability to assess thickness and excursion of the cusps)
Term
Best Echo view for (Supravalvular) Discrete
Definition
PLAX or a high right parasternal view
Term
Best Echo view for (Supravalvular)Coarctation of the Aorta
Definition

Term
Define Ostium Primum Defect
Definition
involves the lower, or primum, portion of the atrial septum and accounts for 15% of ASD in adults
Term
Define Ostium Secundum Defect
Definition
located in the area of the fossa ovalis or middle of the atrial septum, most common type making up two-thirds of all cases
Term
Define Sinus Venosus
Definition
occurs in the superior and posterior septum, near the junction of the SVC, rare—10% of cases
Term
Given a selection of echocardiographic findings, choose the ones that depict why atrial defects are often suspected on the basis of indirect echocardiographic findings
Definition
RV dilation in an otherwise healthy young patient should always suggest an ASD. Abnormal motion of the IVS is another clue. Septal motion in the presence of an ASD is characterized by brisk anterior movement in early systole or flattened motion throughout systole
Term
State the reason why the subcostal approach alleviates the problems seen with the apical approach when evaluating Atrial Septal Defects
Definition
The subcostal 4C view places the atrial septum perpendicular to the ultrasound beam and thereby obviates many limitations of the apical approach. From this window, the fossa ovalis is seen as a thin central region within the atrial septum. This view is also ideal when distinguishing between defects of the primum, secundum and sinus venosus type.
In the apical 4C view the diagnosis of an ostium primum ASD can often be made with confidence from this view, detection of the secundum defect is considerably more difficult. Shadowing and echo dropout (particularly in the area of the fossa ovalis) create the potential for false-positive results.
Term
Given a selection of echocardiographic approaches, choose the most accurate technique for evaluating the interatrial septum
Definition
TEE
Term
Define Perimembranous VSD
Definition
located directly below the aortic valve. The RV surface is adjacent to the septal leaflet of the TV. On the left, the membranous septum forms the superior border of the LVOT. The most common variety of VSD accounting for approximately 80% of all cases
Term
Define Trabecular VSD
Definition
extending from the membranous septum toward the cardiac apex
Term
Define Inlet Septum VSD

Given a list of echocardiographic views, choose the best view for obtaining the most diagnostic information for endocardial cushion defects
Definition
Apical 4C
Term
State the use of transesophageal for the repair of endocardial cushion defects
Definition
During surgery, the use of TEE permits assessment of the adequacy of repair. Most importantly, the presence and severity of residual AV valve regurgitation can be determined.
Term
Define Patent Ductus Arteriosus
Definition
The ductus arteriosus is the normal fetal vascular channel that connects the descending Ao and the main PA, providing a conduit for blood from the RV to the thoracic Ao. Failure of the ductus to close shortly after birth is abnormal, giving rise to the term PDA
Term
Given a list of echocardiographic views, choose the view for obtaining the best visualization of a Patent Ductus Arteriosus
Definition
Suprasternal and high PSAX
Term
Define Total Anomalous Pulmonary Venous Return
Definition
characterized by drainage of all four pulmonary veins into a systemic venous tributary of the RA or into the RA itself
Term
Define Partial Anomalous Pulmonary Venous Return
Definition
when some but not all (usually one or two) of the pulmonary veins connect to the right rather than the LA
Term
Best view for Total Anomalous Pulmonary Venous Return
Definition
parasternal, apical, suprasternal, and subcostal views
Term
Best view for Partial Anomalous Pulmonary Venous Return
Definition
suprasternal, Apical 4C, and subcostal views
Term
State the location of venous confluence of Total Anomalous Pulmonary Venous Connection
Definition
In total anomalous pulmonary venous return, the venous confluence may be located posterior, inferior, or superior to the LA
Term
Define Anomalous Origin of the Coronary Arteries
Definition
origin of the LCX from the RCA sinus and origin of the RCA from the left sinus; in newborns with heart failure, origin of the LCA from the pulmonary truck should be considered
Term
Define Coronary Artery Fistula
Definition
abnormal connection between a coronary artery and another vessel or chamber (either a coronary vein, PA or RV)
Term
Define Coronary Artery Aneurysms
Definition
usually occur in association with Kawasaki disease with a fusiform shape, often are multiple, may occur anywhere along the vessel, and sometimes are lined with thrombus
Term
Best view for Anomalous Origin of the Coronary Arteries
Definition
PSAX at the base (AOV level). In adults, TEE generally provides higher quality images of the proximal coronary arteries and anomalous vessels can be identified with a high degree of accuracy
Term
Best view for Coronary Artery Fistula
Definition
Can be followed by the use of multiple imaging planes and simultaneous color flow imaging
Term
Best view for Coronary Artery Aneurysms
Definition
Detection requires the use of multiple imaging planes. PSAX, PLAX, & apical 4C. TEE can also be used to effectively examine the coronary arteries
Term
Define Tetralogy of Fallot
Definition
4 anatomic features: 1) anterior and rightward displacement of the aortic root, 2) VSD, 3) RVOT obstruction, 4) RVH.
Term
Define Transposition of the Great Arteries
Definition
discordant ventriculoarterial connection in which the aorta arises from the morphologic RV and the PA arises from the LV
Term

Define Hypoplastic Left Heart Syndrome
Definition
Hypoplasia of the LV associated with atresia of the aortic and mitral valves, endocardial thickening, and a small left atrium
Term
Define Single Ventricle
Definition
condition in which a single pumping chamber receives inflow from both atria. A second or rudimentary chamber may be present, but it has no inlet portion (hence, is not a ventricle)
Term
Define Tricuspid Atresia
Definition
characterized by an imperforate TV, hypoplasia of the morphologic RV, an interatrial communication, and a normally developed LV and MV
Term
State the Echo findings for Hypoplastic Left Heart Syndrome
Definition
Echo diagnosis is based on the presence of an abnormally small and underdeveloped LV, usually in association with a dilated RV, aortic root diameter is usually less than 5 mm. A dilated PA can be seen connecting to an enlarged ductus arteriosus
Term
State the Echo findings for Single Ventricle
Definition
With echocardiography, the type of single ventricle can be determined. In the LV type, the rudimentary chamber is anterior and superior to the pumping chamber. In the RV type, it is located more posteriorly. Echo demonstrates two side-by-side inlets without an intervening inlet septum
Term
State the Echo findings for Tricuspid Atresia
Definition
the echocardiographic diagnosis is made from the four chamber view from which the imperforate TV can be visualized directly. Doppler imaging is useful in confirming the absence of flow through the inlet
