Buy Chronic Total Occlusions Assignment
1 Compared with percutaneous revascularization of
nonocclusive coronary lesions, which statement
best characterizes outcomes among patients with
chronic total occlusions when using bare-metal stents
(BMSs)?
(A) Chronic total occlusions have higher rates of
restenosis and reocclusion
(B) Restenosis is higher with total occlusions, but
reocclusion rates are similar
(C) Reocclusion is more frequent among total
coronary occlusions, but restenosis rates are
similar
(D) Rates of both restenosis and reocclusion are
similar
2 Which variable best predictsimprovementin left ventricular function following successful recanalization
of a chronic total occlusion?
(A) History of prior myocardial infarction (MI)
(B) Baseline left ventricular dysfunction
(C) Angiographic presence of collateral flow
(D) Duration of occlusion
3 Compared with conventional BMSs, treatment with
drug-eluting stents (DESs) following recanalization
of chronic total occlusions is associated with all of
the following, except:
(A) Reductions in restenosis
(B) Decrease in repeat target lesion revascularization
(C) Improved survival
(D) Decreased rates of reocclusion
4 Compared with procedural failure to recanalize
chronic total occlusions, successful percutaneous
revascularization of chronic total occlusions is associated with all of the following, except:
(A) Improved long-term survival
(B) Increased need for repeat revascularization procedures
(C) Reduced angina
(D) Improved left ventricular function
5 The most common reason for failure of percutaneous
revascularization of chronic total occlusions is:
(A) Guidewire entry into a subintimal dissection
plane
(B) Inability to cross the occluded segment
(C) Inability to deliver an angioplasty balloon
(D) Coronary artery perforation
6 Which of the following statements regarding coronary perforation in revascularization of total coronary occlusions is true?
(A) In-hospital mortality is similar among patients
who do and do not experience cardiac tamponade
(B) Cardiac tamponade often develops hours following the interventional procedure
(C) Guidewire perforation most commonly occurs
distal to the occluded segment
(D) Angiographic evidence of contrast extravasation
excludes the diagnosis of cardiac tamponade

7 Which of the following statements regarding collateral flow in chronic total occlusions is not true?
(A) Collateral function is worse in patients with
impaired regional wall motion
(B) The presence and extent of collateral flow
predicts improvement in ventricular function
following revascularization
(C) Collateral function regresses after recanalization
of chronic total occlusions
(D) Growth factor expression is related to collateral
function and the duration of occlusion
8 Which of the following technologies/strategies has
demonstrated significantly higher procedural success over coronary guidewires in a randomized
trial?
(A) Excimer laser guidewire
(B) Fibrinolytic infusion
(C) Optical coherence tomography guidewire
(D) None of the above
