Long-term Effects of Endobronchial Valve Implantation on Cardiac Function and Skeletal Muscle Function in Patients With Lung Volume Reduction Surgery
The goal of this type of study: clinical trial is to evaluate the effect of bronchial valve implantation on cardiac function and skeletal muscle function in Chronic Obstructive Pulmonary Disease. The main question it aims to answer are:evaluate the effect of bronchial valve implantation on cardiac function and skeletal muscle function. Participants will undergo Lung volume reduction surgery with endobronchial valve implantation.
