What treatment procedure may lead to decreased right ventricular function?

The correct response relates to the fact that heart transplantation is a complex surgical procedure that involves removing a failing heart and replacing it with a healthy donor heart. During this process, there may be a period of adjustment for the transplanted heart and the right ventricle, particularly if there are complications such as graft dysfunction or rejection, which can lead to decreased right ventricular function.

In the case of heart transplantation, the right ventricle may experience changes in hemodynamics and workload, particularly if it takes time for the new heart to adapt to the circulatory demands of the patient. Additionally, the use of immunosuppressive medications following transplantation can impact myocardial function, further contributing to potential decreases in right ventricular performance.

Other procedures listed, such as cardiac catheterization, coronary artery bypass grafting, and pacemaker insertion, typically aim to improve cardiac function or treat existing heart conditions. While they may have risks, they are generally designed to enhance myocardial performance rather than lead to decreased right ventricular function.
