right heart cath for pulmonary hypertension

Right heart catheterization is a crucial diagnostic tool for pulmonary artery hypertension (PAH). This procedure allows for precise measurement of pulmonary artery pressures, assessment of cardiac function, and informs the selection of subsequent treatment strategies. It is widely recognized as the gold standard for diagnosing PAH. During the procedure, a thin catheter is inserted through the patient's femoral or jugular vein, guided to the right atrium, right ventricle, and ultimately into the pulmonary artery. This enables the physician to measure pressures at various sites, gauge blood flow, and ascertain the presence of PAH. Additionally, blood samples can be drawn through the catheter for blood gas analysis to further evaluate pulmonary function. While right heart catheterization is generally safe, it carries certain risks, including bleeding, infection, and arrhythmias. Prior to the procedure, patients should engage in thorough communication with their physician to understand its objectives, steps, and potential risks. Patients are also advised to follow the doctor's instructions for preparation, such as fasting and discontinuing certain medications. During the procedure, it is important for patients to remain relaxed and cooperative with the medical team to facilitate a smooth process. Post-procedure, patients should follow the guidance of healthcare professionals for recovery, monitor their health, and promptly report any discomfort to their physician.
