Buy History Of Tuberculous Pericarditis
In the setting of aortic dissection, which of the
following statements is incorrect?
(A) Pericardial effusion coincides with 17% to 45%
of cases
(B) Pericardial tamponade occurs most frequently
with a De-Bakey type I dissection
(C) Pericardiocentesis may cause extension of the
dissection
(D) Surgery should be performed as soon as possible
8 In patients with large malignancy-related pericardial
effusion treated with percutaneous balloon pericardiotomy, which of the following is incorrect?
(A) Fever occurs in approximately one third of
patients post procedure
(B) Recurrence rate at 4 months is approximately
50%
(C) Results with immediate and deferred procedures
are similar
(D) Lung and breast cancer associated effusions are
most common
9 A 64-year-old man with a history of alcohol dependency presented to the emergency room with
increasing dyspnea, chronic cough, hemoptysis, and
persistent fever. Echocardiography confirms the
presence of a large pericardial effusion. Simultaneous right atrial pressure and pericardial opening
pressure are shown in the following figure. Regarding this hemodynamic tracing, which of the following
statements is incorrect?
(A) The X descent during ventricular systole is the
dominant waveform
(B) The right atrial and pericardial pressures fall
during inspiration
(C) With increased pericardial fluid accumulation,
the X descent will become less prominent and
the Y decent more pronounced
(D) RV mid-diastolic pressure may be elevated and
equal to the right atrial and pericardial pressure
10 The patient discussed in Question 9 had a cardiac
CT (short axis shown in the following figure) on
admission. He had a reasonable symptomatic response to pericardiocentesis and his pericardial pressure returned to zero post-tap; however, his right
atrial pressure remained elevated. On the basis of
his findings on cardiac CT scan and his hemodynamic parameters, a presumptive diagnosis of
effusive-constrictive pericarditis was made. Which
of the following findings does not support this diagnosis?
264 900 Questions: An Interventional Cardiology Board Review
(A) Equalization of the right and left ventricular end
diastolic pressures
(B) A prominent dip and plateau waveform in the
right ventricular tracing
(C) Concordance between the left and right ventricular systolic pressures
(D) Right ventricular end systolic pressure <50
mm Hg

11 Mycobacteriumtuberculosiswasfound in the same patient’s (discussed in Questions 9 and 10) pericardial
fluid. Which of the following statements regarding
tuberculous pericarditis is incorrect?
(A) Pericardial constriction occurs in 10% to 15%
of cases
(B) The mortality rate approaches 85% in untreated
cases
(C) A rapid diagnosis can be made from a small volume fluid sample by polymerase chain reaction
(PCR)
(D) The tuberculin skin test is falsely negative in
25% to 30% of cases
12 A patient with a history of tuberculous pericarditis
presents with progressively increasing dyspnea and
undergoes the noninvasive study depicted in the
following figure. Regarding this investigative study,
which of the following statements is correct?
(A) The image on the left represents evidence of
pericardial constriction and tethered movement
of the heart
(B) The images represent CT scan tagging, which
can be used to diagnose pericardial constriction
(C) Pericardial thickening is absent in approximately 18% of cases of constrictive pericarditis
(D) Pericardiectomy for constrictive pericarditis has
a mortality rate of 1% to 2%
