Which condition is characterized by decreased RV compliance as seen on a CVP tracing?

The correct answer is tricuspid or pulmonic stenosis. This condition is characterized by an obstruction to blood flow across the right heart valves, resulting in decreased right ventricular (RV) compliance. When the right ventricle cannot adequately fill due to the narrowed valve opening, it leads to increased pressure in the right atrium and subsequently influences the central venous pressure (CVP) tracing. In CVP monitoring, this will manifest as a plateau or a more pronounced "wedge" appearance on the tracing due to the elevated pressures.

When assessing how tricuspid or pulmonic stenosis impacts the right ventricle, it is important to recognize that the heart's ability to expand and contract effectively is compromised. The resulting back pressure can lead to systemic venous congestion as blood backs up into the systemic circulation, reflecting abnormal compliance on CVP tracing.

The other options presented do not specifically tie to a direct decrease in RV compliance as seen in the CVP readings. For example, atrial flutter primarily affects the atrial rhythm without necessarily impacting ventricular compliance. Acute coronary syndrome involves myocardial ischemia that affects the heart muscle itself but does not inherently describe the hemodynamic profile seen in CVP tracing caused by valvular stenosis. De
