This article discusses the use of exercise tests to aid in the decision-making process for pulmonary valve replacement in patients with pulmonary valve regurgitation (PVR). The study evaluated cardiopulmonary exercise tests (CPET) performed on patients with PVR and compared them to a control group without PVR. The researchers introduced new CPET parameters to analyze the O2pulse before and after exercise. The results showed that classic CPET parameters did not provide any benefit in the decision process, but the duration of elevated O2pulse after peak exercise was significantly different between the two groups. The authors suggest that the O2pulse could be a surrogate parameter for stroke volume and may indicate RV remodeling and increased stiffness. [Extracted from the article] |
