These patients often have coexisting cardioaortic disease and internal carotid artery disease, rendering it difficult to identify which vessel is the culprit source of embolus in many cases. Younger patients (<55 yrs old) with embolic strokes are less likely to have significant _______________ disease, and more likely to have cardiogenic sources of embolus or hypercoagulable states.cardiacOther systemic emboli—those targeting the eye, kidney, spleen, or skin—are usually the result of vegetation or thrombus shed from an abnormal or prosthetic _________ valve, or the result of atheromatous debris dislodged by intra-arterial catheter procedures.pulmonaryA ____________ embolus is the result of a deep venous thrombosis, which has broken free and traveled to the lung bed.thrombus, vegetations, myxoma, fibroelastoma, thromboemboliPotential cardiovascular etiologies of stroke A.

(these are small fatty lumps that develop on the inside of vessel walls).plaques, thrombusCalcified __________ tend to appear very jagged and echobright, and associated ____________ can appear as tethered but mobile elements. ____________ (same as first) that are more than 4 mm in thickness, or which contain mobile or protruding elements, are associated with a higher risk of stroke.atrial fibrillationThe presence of _________ ____________, particularly in the presence of rheumatic heart disease, increases the risk of atrial thrombus formation.spontaenous echoAtrial thrombi often occur in association with _____________ ______ contrast, which is thought to represent increased fibrin and red blood cells in the early stages of coagulation.thrombiAlthough TTE often does not fully visualize the left atrial appendage, __________ may occasionally be seen in the body of the left or right atrium. Figure 4 is a parasternal short-axis view of a ____________ (same thing, singular) within the left atrial appendage.aneurysmal, thrombusThe presence of a dyskinetic or _____________ area of left ventricle in a patient with a history of myocardial infarction should always prompt evaluation for an associated intramural ____________, which can vary greatly in shape and mobility.stenosis, calcification, prolapseMitral __________, stranding, and mitral annular ____________ have all been suggested to be associated with risk of embolus, although there are often confounding risk factors. Mitral valve ___________ was historically implicated as a risk factor, but this appears to be an artifact of overdiagnosis of mitral valve prolapse in this population (elderly), rather than comprising a true etiological substrate.vegetations, echodensities, shadowingBacterial _____________ are more likely to occur on abnormal native valves, such as bicuspid aortic or myxomatous mitral valves. Prosthetic valve thrombus or vegetation may be detected as independently mobile _____________, predominantly located on the low-pressure side of the valve. On mechanical prosthetic valves, the masses may not be clearly visualized because of acoustic _____________ by the prosthesis, but if one or more discs appear immobile or an unusually high transvalvular gradient is detected by Doppler, suspicion for obstruction remains high and a TEE should be performed.valves, embolizeThe epidemiology of cardiogenic emboli in younger patients is different from that of older subjects. Those with abnormal native _________, such as myxomatous or prolapsed mitral valve or bicuspid aortic valves are susceptible to endocarditis and resultant vegetation, which can ___________.10In the young, vegetations which are more than ____mm are at the highest risk for causing embolic complications.myxomasAmong intracardiac tumors, __________ are also more often found in younger patients owing to embolization.paradoxical, intracardiac, dilated____________ embolus is a well-known risk of congenital heart disease with _____________ shunting, as in the case of atrial septal defects or ventricular septal defects. The presence of a ___________ right atrium and/or right ventricle in the absence of other causes should prompt adiligent search for intracardiac shunting by both two-dimensional imaging and Color Doppler.pfo, intracardiac______ is a condition in which the ostium primum arises from the left atrial side and spans the fossa ovalis, but does not fuse completely with the apposing ostium secundum. ______ (same as first blank; don't type) is essentially a normal variant, occurring in 25-30% of the population. Under conditions in which right atrial pressure exceeds left atrial pressure, the ________(same as first and second blank; don't type) can allow right-to-left _____________ flow to occur (similar to a trap door or flap).septum, interatrial, subcostalThe potential channel of the PFO is typically not visible on two-dimensional echocardiography, although increased mobility of the ________ in the fossa ovalis area can be a clue to the presence of one. A careful color Doppler scan of a sector zoomed in on the _________ septum, particularly in the ___________ window, can occasionally detect flow across the PFO as a narrow red jet of transient left-to-right flow.bubble study, shuntingA "__________ ________" or injection of intravenous saline that has been agitated with air to produce echo contrast, is an echocardiographic method used to detect PFO. Because the bubbles produced by agitation within a syringe are relatively large and usually filtered by the pulmonary bed, the appearance of echogenic bubbles in the left side of the heart immediately (within six beats of opacifying the right atrium) is indicative of right-to-left ___________.left, right, PFOBecause ______ atrial pressure is usually higher than ________ atrial pressure, manuevers, which transiently increase right atrial pressure such as the Valsalva maneuver, coughing or sniffing, abdominal compression, or raising the legs can increase the sensitivity of a bubble study for detecting ______.pfos, stroke_____ can allow paradoxical emboli from the venous system to lodge in the systemic arteries, although the actual passage of a thromboembolus through a PFO is only rarely captured on echocardiographic views. The incidence of PFO appears to be higher in patients with ischemic _______ , exceeding threefold higherin patients younger than 55 yr old.atrial septal aneurysm, pfo, 10An ________ _________ ___________(ASA) is an excessively redundant hypermobile area of the interatrial septum,which can be seen on echocardiogram. It is very frequently associated with ______, and typically involves the area of the fossa ovalis, but can extend to include the surrounding limbic areas or even the entire interatrial septum. The criteria for the diagnosis of ASA vary, but it is generally accepted that maximal excursion of the interatrial septum more than _____ mm from centerline defines an ASA.embolic, aspirinThe incidence of both a PFO and an ASA is markedly increased in patients with ________ stroke, more than 15-fold in one meta-analysis. Options for therapy and secondary risk prevention at this point include_________, plus additional anticoagulation and/or closure ofthe PFO by surgery or transcatheter devices.youngerThe utility and yield of echocardiography in searching for a presumed cardiac source of embolus will vary with patient's age and comorbidities. Echocardiography is more likely to be useful in __________ patients, or those with known predisposing cardiac conditions. In contrast, the workup of most elderly patients with a stroke should start with an imaging modality of the internal carotid arteries .peripheral, visceral, cerebrovascular, neurologicalClass I (definitely proven to be of benefit) American College of Cardiology/American Heart Association guidelines for clinical application of echocardiography in neurological disease include: 1. Patients of any age with abrupt occlusion of a major ___________ or ___________ artery. 2. Younger patients (<45 yr) with _______________ events. 3. Older patients (>45 yr) with ____________events, without evidence of cerebrovascular disease or other obvious causes. 4. Patients for whom a clinical therapeutic decision (e.g., anticoagulation) will depend on the results of the echocardiogram.secundum, patency_____________ ASDs are one of the most frequently encountered congenital cardiac defects in clinical practice along with bicuspid aortic valves. The lesion results from the incomplete development of the septum secundum, leaving a central ___________ between the right and left atria.fenestrated, pulseOccasionally, there may be more than one opening in the septum so that a ___________ septum results. This is often clearly delineated on transthoracic imaging with the use of color flow Doppler around the area of the central portion of the septum. Shunt flow can be seen with the use of ________ wave Doppler across the defectcontraction, negative contrast, IVCUsually some transient right-to-left shunting can be seen with these defects, typically corresponding with ventricular ____________. Occasionally, with the use of intravenous agitated saline in the right heart, an echolucent silhouette of blood flow may be seen in the right atrium when predominant left-to-right shunting is present, the so-called "____________ __________ effect." However, because saline contrast is often injected from an upper extremity, this "negative contrast effect" should be interpreted with caution as this can also be produced by contrast-free caval blood flow emanating from the _______ flushing against the area of the fossa ovalis.aneurysms, hypermobile, Lutembacher'sOccasionally, atrial septal _____________ may be seen with secundum ASDs. In these cases, the atrial septum is ____________ and bows into either atrial chamber, varying with respiratory variation. When rheumatic involvement of the mitral valve is concomitantly present with an ASD, ______________ syndrome is said to be present.primum_________ASDs result from the incomplete development of the septum primum with the endocardial cushions in the region of the atrioventricular (AV) valves.mitral, regurgitationAlso called partial AV canal defects, this lesion (primum ASD) results in an atrial communication that is seen inferiorly, in the lower portion of the atrial septum that normally is fused with the AV valvular apparatus. The AV valves are therefore affected, typically involving the ________ valve, where a cleft may be seen in the anterior leaflet. Mitral _____________ may also be seen. Interventricular shunts are not generally seen with this abnormality.echolucentThe features of a primum ASD defect can usually been seen with transthoracic imaging. In the four-chamber view (apical or subcostal), the AV valves may appear to lieon the same plane, forming a "T," referring to the alignment of the AV valves with the ventricular septum. An ___________ space can be seen above the AV valves, usually with a nonrestrictive shunt seen by color flow Doppler. The "goose neck" deformity seen angiographically on left ventriculography can occasionally be seen echocardiographically as an abnormal appearing left ventricular outflow tract.sinus venosus, SVCThe ________ __________ ASD is an interatrial communication that arises near the junction of the vena cava with the right atrium. Therefore, this defect can present in two distinct morphologies. More commonly, the defect is located superiorly at the site of the _____ drainage to the right atrium but can be present inferiorly at the junction of the IVC and right atrium. In either case, these defects may be difficult to define anatomically via transthoracic imaging alone. However, transesophageal echocardiography can easily define the defect and any associated pathology.coronary sinusA ___________ ________ ASD is a rare type of ASD that presents an interatrial communication via an unroofed coronary sinus. Therefore, the defect is seen at the site of origin of the coronary sinus. A persistent left SVC is associated with this defect and can often be seen to drain into the coronary sinus or left atrium.coronary sinusA __________ ________ ASD may not be visualized on routine transthoracic echocardiography. However, the defect may be suggested by the constellation of right heart overload, a dilated coronary sinus, and the presence of a persistent left SVC. Multiplane transesophageal echocardiography should be used to confirm the presence of this defect and associated pathology.patent foramen ovale, pfoA __________ __________ ________ or ______ is not a true defect in embryological development of the either the septum primum or secundum. Rather, this lesion is the result of the failure of permanent fusion of the normally developed atrial septa.Valsalva, coughingA dynamically patent orifice acting similar to a flap valve is present in patients with a PFO and may respond to interatrial pressure changes.Thus a right-to-left shunt may be present when right atrial pressures increase higher than left atrial pressures, such as with ___________, ___________, and so on. The defect may be functionally sealed when left atrial pressures exceed right, with only occasional right-to-left shunting.saline, ValsalvaThe presence of a PFO defect is easily evaluated with agitated _________ contrast injection. Normally, the procedure is performed with and without _________ maneuver, as right-to-left shunting may not be seen under baseline conditions. The presence of contrast bubbles early after appearance in the right heart indicates the presence of right-to-left shunting.atrial septal defect, left, right_____ _____ ____ is an acyanotic congenital heart defect with _____ to _____ shunt.congenital, females, sizeAtrial Septal Defect is the most common ______ abnormality in adults, it is more prevalent in _____, the severity depends on the _____ of the defect.secundum, primum, venosus, coronaryThe four types of Atrial Septal Defect are septum ______, septum _____, sinus _____, and _____ sinus defect.secundum, primum, venosus, coronaryTypically _____ and _____ septal defects can be seen with a TTE.

There may be some failure to _____ and ______ upper respiratory tract infections.arrythmias, pulmonary, bidirectional, CHFLater in life many patients with ASD's will develop atrial ______, ______ hypertension, _____ and then right to left shunting which will ultimately lead to _____.Qp/QsThe ____/____ ratio can be used to measure the hemodynamic impact of the ASD.pulmonary, aorticThe Qp/Qs ratio can be found by calculating flow across the _____ valve and dividing this by the flow across the _____ valve. Flow is calculated by multiplying the CSA of the outflow tract with the VTI .π x (radius of RVOT)^2 x RVOT VTI ____________________________________ π x (radius of LVOT)^2 x LVOT VTIQp/Qs formula is:C. The most common primary benign intracardiac tumor is the myxoma.
