The client has just returned to the floor after balloon valvuloplasty of the aortic valve and the nurse is planning appropriate assessments.
The nurse would assess for all potential complications except.

Choice A rationale

Thickening of the ventricular walls and the septum is the hallmark of hypertrophic cardiomyopathy, not pericarditis. In that condition, the muscle tissue becomes abnormally thick, which can make it harder for the heart to pump blood and may lead to arrhythmias. Pericarditis does not involve the growth or thickening of the myocardium itself; it is strictly a disorder of the protective layers surrounding the heart. Explaining the condition this way would be scientifically inaccurate.

Choice B rationale

Acute pericarditis is defined as the inflammation of the pericardium, which is the thin, two-layered membranous sac that encloses the heart. This inflammation often leads to chest pain that worsens with deep breathing or lying flat and may produce a pericardial friction rub. The inflammation can be caused by infections, autoimmune disorders, or trauma. This statement correctly identifies the anatomical location and the pathological process involved, making it the most appropriate explanation for patient education.

Choice C rationale

Excessive stretching of the ventricles is associated with dilated cardiomyopathy, a condition where the heart chambers enlarge and the muscle weakens. This stretching results in a decreased ejection fraction and signs of heart failure. Pericarditis involves the external sac and does not primarily cause the heart muscle to stretch out. Using this description would confuse the patient about the nature of their diagnosis, as it describes a structural muscle failure rather than an inflammatory process.

Choice D rationale

Compression of the myocardium due to fluid accumulation describes a pericardial effusion or cardiac tamponade. While these can be complications of acute pericarditis, they are not the definition of the disease itself. Pericarditis is the inflammation of the membranes, which may or may not lead to significant fluid buildup. It is important to distinguish the primary inflammatory cause from the potential secondary effect of fluid pressure to ensure the patient understands why they have pain.

Choice A rationale

A pacemaker is a device used to treat electrical conduction disturbances, such as bradycardia or certain heart blocks. It does not provide the mechanical circulatory support required for a patient whose heart is failing while awaiting a transplant. While it manages rhythm, it cannot replace the pumping function of the heart. Therefore, it is not considered a bridge to transplant for end stage heart failure where the primary issue is pump failure.

Choice B rationale

A Ventricular Assist Device is a mechanical pump that is surgically implanted to help the weakened ventricles circulate blood throughout the body. It is the gold standard bridge to transplant because it effectively takes over the workload of the heart, allowing the patient to stabilize and sometimes even return home while waiting for a donor organ. It improves organ perfusion and functional capacity, making the patient a better candidate for the eventual surgery.

Choice C rationale

An Intra aortic balloon pump is a temporary device used primarily in acute settings, such as cardiogenic shock, to improve coronary perfusion and decrease afterload. It is usually short term and requires the patient to remain in an intensive care unit, often with limited mobility. While it supports the heart, it is generally not used as a long term bridge to transplant compared to the more durable and mobile ventricular assist devices available.

Choice D rationale

An Implanted Cardioverter Defibrillator is designed to detect and terminate life threatening ventricular arrhythmias by delivering a shock. While patients awaiting transplant often have these devices to prevent sudden cardiac death, the ICD does not provide any mechanical assistance to the failing heart muscle. It manages the risk of death from an electrical event but does not address the underlying hemodynamic failure or act as a functional bridge for circulation.
