Ventricular Assist Device (VAD-C) Exam Review
Course Exam | Latest Verified Questions and Detailed
Answers
OVERVIEW DESCRIPTION:
The Ventricular Assist Device (VAD-C) Exam Review Course provides a comprehensive
overview of the core knowledge required for healthcare professionals caring for patients with
advanced heart failure requiring mechanical circulatory support. This review covers critical
topics including patient selection and indications for VAD therapy (such as bridge to transplant
and destination therapy), device types and mechanics, hemodynamic monitoring, and the
interpretation of key parameters like flow, speed, power, and pulsatility index. A major focus is
placed on the recognition and management of common complications, including pump
thrombosis, hemolysis, right ventricular failure, driveline infections, and anticoagulation-related
bleeding. Additionally, the course addresses essential emergency protocols, patient education for
safe discharge and home management, and the importance of a multidisciplinary approach to
optimize patient outcomes.
QUESTION 1
What is the primary clinical purpose of a Ventricular Assist Device (VAD)?
A. To permanently replace the human heart
B. To support cardiac output in patients with severe heart failure
C. To cure dilated cardiomyopathy
D. To prevent the occurrence of ventricular arrhythmias
CORRECT ANSWER: B
EXPERT RATIONALE: VADs are mechanical pumps designed to support circulation in
patients with advanced heart failure, either as a bridge to transplant, recovery, or
destination therapy.
QUESTION 2
A 65-year-old patient with end-stage heart failure is not a candidate for heart
transplantation due to advanced age and comorbidities. What VAD strategy is most
appropriate for this patient?
A. Bridge to transplantation (BTT)
,2|Page
B. Bridge to recovery (BTR)
C. Destination therapy (DT)
D. Bridge to candidacy (BTC)
CORRECT ANSWER: C
EXPERT RATIONALE: Destination therapy is the use of a VAD as a permanent support
for patients with end-stage heart failure who are not eligible for heart transplantation.
QUESTION 3
According to the NYHA classification, which symptom profile would most warrant
evaluation for VAD therapy?
A. Symptoms with moderate exertion
B. Symptoms with minimal exertion
C. Symptoms at rest despite optimal medical management
D. No symptoms with ordinary physical activity
CORRECT ANSWER: C
EXPERT RATIONALE: NYHA Class IV patients, who have symptoms at rest despite
maximal medical therapy, are typically considered for advanced therapies like VAD
implantation.
QUESTION 4
Which hemodynamic finding is a key indicator for VAD candidacy in a patient with
advanced heart failure?
A. Cardiac index > 2.5 L/min/m²
B. Cardiac index < 2.2 L/min/m²
C. Pulmonary capillary wedge pressure < 15 mmHg
D. Mixed venous oxygen saturation > 65%
CORRECT ANSWER: B
EXPERT RATIONALE: A low cardiac index ( < 2.2 L/min/m² ) indicates poor cardiac
output and severe cardiac dysfunction, supporting the need for mechanical circulatory
support.

QUESTION 5
Which of the following is considered an absolute contraindication for VAD
implantation?
A. Controlled type 2 diabetes mellitus
B. A history of treated prostate cancer 10 years ago
C. An active, uncontrolled systemic infection
D. Mild chronic obstructive pulmonary disease (COPD)
CORRECT ANSWER: C
EXPERT RATIONALE: Active uncontrolled infection poses an unacceptably high risk of
sepsis and device seeding, making it an absolute contraindication for VAD implantation.
QUESTION 6
A patient is being evaluated for a VAD and has a history of non-compliance with
medications and follow-up appointments. How does this impact their candidacy?
A. It has no impact on surgical candidacy
B. It is a relative contraindication due to risk of poor post-operative management
C. It is only a concern if the patient is over 70 years old
D. It makes them a better candidate because they are independent
CORRECT ANSWER: B
EXPERT RATIONALE: Successful VAD therapy requires strict adherence to complex
care routines, including driveline care, anticoagulation monitoring, and follow-up; non-
compliance significantly increases the risk of adverse events.
QUESTION 7
Pre-operative assessment of right ventricular function is critical in VAD candidates
primarily to predict the risk of:
A. Post-operative atrial fibrillation
B. Right ventricular failure after LVAD implantation
C. Aortic valve regurgitation
D. Driveline infection
CORRECT ANSWER: B
, 4|Page
EXPERT RATIONALE: LVAD implantation increases venous return to the right heart,
and if the right ventricle is already compromised, it can fail, leading to significant
morbidity and mortality.
QUESTION 8
Which laboratory finding would be most concerning as a contraindication for VAD
placement due to poor prognosis?
A. Mildly elevated LDL cholesterol
B. Elevated serum bilirubin indicating liver dysfunction
C. Low hemoglobin of 11.5 g/dL
D. Slightly elevated BUN
CORRECT ANSWER: B
EXPERT RATIONALE: Severe liver dysfunction (often reflected by high bilirubin)
suggests end-organ damage from heart failure or cirrhosis, which is associated with
poor outcomes and increased bleeding risk post-implantation.
QUESTION 9
What is the primary reason for performing a right heart catheterization as part of the
VAD candidacy workup?
A. To visualize coronary artery blockages
B. To accurately measure pulmonary pressures and calculate pulmonary vascular
resistance
C. To assess the structure of the mitral valve
D. To determine the exact size of the left ventricle
CORRECT ANSWER: B
EXPERT RATIONALE: Right heart catheterization provides direct hemodynamic
measurements (e.g., pulmonary artery pressure, PCWP) essential for confirming the
severity of heart failure and ruling out fixed, irreversible pulmonary hypertension.
QUESTION 10
Pump thrombosis is a serious complication of VAD therapy. Which laboratory value is
