CCI - Cardiovascular Credentialing International Invasive Catheterization Procedures Questions and Answers

Question 1

A patient in the cardiac cath lab has the following right heart pressures recorded: Right Atrium (RA) mean = 15 mmHg, Right Ventricle (RV) = 45/15 mmHg, Pulmonary Artery (PA) = 45/25 mmHg, and Pulmonary Capillary Wedge Pressure (PCWP) = 22 mmHg.
These findings are most indicative of which condition?

Accepted Answer

Left-sided heart failure

Answer

Severe pulmonic stenosis

Answer

Cardiac tamponade

Answer

Normal hemodynamics

Question 2

During a right heart catheterization, the equalization of end-diastolic pressures across all four cardiac chambers (e.g., RA, RV, PA diastolic, and PCWP are all within 5 mmHg of each other) is a classic hemodynamic sign of which condition?

Accepted Answer

Constrictive pericarditis

Answer

Mitral regurgitation

Answer

Aortic stenosis

Answer

Restrictive cardiomyopathy

Question 3

A patient undergoes a left heart catheterization via the right femoral artery. Several hours post-procedure, the patient complains of severe low back pain and becomes hypotensive and tachycardic. Which of the following complications should be suspected first?

Accepted Answer

Retroperitoneal bleed

Answer

Pseudoaneurysm at the access site

Answer

Femoral artery thrombosis

Answer

Arteriovenous fistula

Question 4

The Gorlin formula is a standard calculation used in the cardiac catheterization lab to determine which of the following parameters?

Accepted Answer

Aortic valve area

Answer

Cardiac index

Answer

Mitral regurgitant fraction

Answer

Pulmonary vascular resistance

Question 5

When engaging the left main coronary artery with a catheter, the pressure waveform abruptly changes, showing a sharp drop in diastolic pressure and a morphology that resembles a left ventricular tracing. This dangerous phenomenon, known as 'ventricularization,' is a critical sign of what?

Accepted Answer

Significant left main coronary artery stenosis

Answer

Successful passage into the left ventricle

Answer

Severe aortic regurgitation

Answer

Severe mitral stenosis

Question 6

Which of the following invasive measurements is used to assess the functional significance of a moderate coronary artery stenosis by calculating the ratio of pressure distal to the stenosis to the aortic pressure during maximal hyperemia?

Accepted Answer

Fractional Flow Reserve (FFR)

Answer

Intravascular Ultrasound (IVUS)

Answer

Optical Coherence Tomography (OCT)

Answer

Ankle-Brachial Index (ABI)
