2022 Cardio Residents exam Flashcards
Most common type of valve dysfunction in adults. (Requisites 281)
Mitral Regurgitation
Most common cause of constrictive pericarditis?
Post pericardiotomy
Most common abnormality of the pericardium
Pericardial effusion
BRANT: Pericardial effusion is the most common abnormality of the pericardium. The normal pericardial stripe is 2 to 3 mm on chest radiograph and CT and less than 4 mm on MR. Plain films show thickening of the pericardial stripe or differential density sign in up to 63% of patients with pericardial effu- sions. The water-bottle configuration is seen in chronic effu- sions. Fluoroscopy shows decreased cardiac pulsations. The normal pericardium contains approximately 20 mL of fluid, whereas it takes approximately 200 mL to be detectable by plain film. Echocardiography detects very small quantities (50 mL) of pericardial fluid, usually as a posterior sonolu- cent collection (Fig. 22.45). Small effusions (100 mL) will appear as anterior and posterior sonolucent regions. Moderate-sized effusions (100 to 500 mL) demonstrate a sonolucent zone around the entire ventricle. Very large effu- sions (500 mL) extend beyond the field of view and may be associated with the “swinging heart” inside the pericardium.
Most common type of cardiomyopathy
Dilated CM
Brant
What is the most common form of single ventricle?
Underdeveloped right ventricle
Most common cause of congestive heart failure in the first day of
life?
Hypoplastic left heart syndrome
Swischuck
Type 2 endoleak is the most common complication encountered in
the endovascular repair aneurysms. The classic finding noted in this type
of endoleak is ___. (Requisites p. 314)
Collateral vessels supplying the aneurysmal sac
Journal: Type II is the most common, making up 10–25% of all endoleaks (10). They occur from retrograde collateral blood flow into the aneurysm sac, typically from a lumbar artery or the inferior mesenteric artery (IMA).
What is the most common type of thoracic aortic aneurysm?
(Requisites p. 325)
Fusiform
The most common site of an infected aneurysm is the _____.
(Requisites p. 332)
Femoral artery
Acute ischemia of the lower extremity, in the absence of occlusion of
a bypass graft, is most often the result of ____. (Brant p. 634)
Embolism
What is the most common site of atherosclerotic involvement in the
upper extremity? (Brant p. 633)
Subclavian artery
Dilated cardiomyopathy accounts for 90% of all cardiomyopathies.
What is its most common cause? (Brant 4th ed., p. 603)
Chronic infarction
Dilated cardiomyopathy accounts for 90% of all cardiomyopathies.
What is its most common cause? (Brant 4th ed., p. 603)
Ischemic cardiomyopathy
Which is TRUE about restrictive cardiomyopathy? (Brant 4th ed., p.
604)
A. The primary differential diagnosis is hypertrophic cardiomyopathy.
B. It is the most common form of cardiomyopathy.
C. Early in the disease, ventricular systolic function is severely impaired.
D. Etiologies include in lnfiltrative disorders such as amyloid, glycogen storage
disease, hemochromatosis, sarcoidosis.
D
It is in fact the least common, primary Ddx is constrictive CM, diastollic impaired early in disease
What is the MOST COMMON course abnormality of the coronary
arteries? (Webb 3rd ed., p. 2820)
Myocardial Bridge
. Most common congenital heart abnormality? (Brant 4th Ed p. 1164)
BIcuspid aortic valve
Bicuspid aortic valve is most common in males and is present in 25% to 50% of patients with aortic coarctation. Of patients with a bicuspid aortic valve, 60% of those older than 24 years of age have calcification within the bicuspid valve
Coarctation of the aorta is a primary abnormality of the media with eccentric narrowing of the aortic lumen due to infolding of the aortic wall (Fig. 23.3A). Approximately 70% are associated with congenital cardiac anomalies, the most common being bicuspid aortic valve.
What is the most common type of valvular stenosis seen in Tetralogy
of Fallot? (Brant 4th Ed p. 1172)
Subvalvular (infundibular)pulmonary stenosis
Which statement refers to the second most common dextroposition?
(Swischuk p. 295-297)
a. Situs inversus always present
b. Associated congenital heart disease is common
c. Complete inversion of cardiac chambers
d. Normal anteroposterior chamber relationships
Associated congenital heart disease is common
On the other hand… The most common type of dextrocardia is so-called “mirror image dextrocardia.” In these cases, the cardiac apex points to the right, and there is complete inversion of the cardiac chambers. In other words, the left atrium and ventricle become right sided, and the right atrium and ventricle become left sided (Fig. 3.106A). Normal anteroposterior chamber relationships, however, are preserved. Situs inversus is always present, bur generally, there is no increased incidence of congenital heart disease
What is the most common congenital pericardial defect? (Swischuk
p.317)
Complete absence of the left pericardium
Pericardial defects are much more common on the left than on the right, and of those occurring on the left, complete absence
of the left pericardium is the most common (1). Fortunately, this particular anomaly is relatively benign and requires no specific treatment.
- What is the target heart rate for cardiac CT? (Requisites p. 144, Brant p.589)
60-70 bpm
Regarding ECG-gated CT acquisition. Which DOES NOT describe
prospective gating? (Requisities, p. 201)
Has the advantage of lower radiation dose compared to retrospective gating
X Complete datasets in any phase of the cardiac cycle is acquired
The scanner will usually acquire images during late diastole when the heart is most quiescent
The scanner will only acquire x-ray projections in a prespeci ed phase of the
cardiac cycle
Retrospective gating allows acquiring unlimited complete datasets in any phase of the cardiac cycle. This approach uses a spiral CT acquisition, in which the x-ray current remains turned on during the entire scan. The user may then in retrospect define what phase of the cardiac cycle to reconstruct. The major advan- tage of this approach is that the interpreter may decide to try a different phase of the cardiac cycle if the initial reconstruction demonstrates motion artifact. Another advantage is the ability to “edit” the ECG.
A calcium score of 11-100 indicates minimal plaque burden and signi cant
coronary artery disease is very unlikely. *
One method of scoring utilizes the Agatston method where coronary calcification is defined as an area with greater than 130 HU and larger than 2 mm2.
Stenoses greater than __% are considered hemodynamically
significant. (Brant p. 588). Narrowing of the coronary artery diameter by
__ % roughly predicts cross-sectional area reduction by approximately
75%. This is the physiologic point at which flow is restricted enough to
result in ischemia under stress conditions. (Brant p. 598)
stenoses >50%
The patient’s heart is right-dominant if the right coronary artery
supplies what? (Brant p. 583)
The posterior descending artery and the posterior and inferior surface of the
myocardium
