Background
Left ventricular outflow tract pressure gradient (LVOTG) measurements are very common in cardiac interventional procedures and play a very important role in the diagnosis and treatment of aortic stenosis, hypertrophic obstructive cardiomyopathy, in particular. The LVOTG measurement needs to monitor the pressure of the left ventricle and the aortic root at the same time for calculation, and the conventional catheter can only measure one pressure at present, so that two paths (such as a left radial artery and a right radial artery) for a patient need to be accessed, one catheter is respectively implanted, and the pressure is synchronously obtained, which obviously increases the pain of the patient, the incidence rate of complications and the complexity of clinical operation; in clinical practice, some physicians use only one catheter (such as a pigtail catheter) to measure the left ventricular pressure first, then withdraw the catheter to the aortic root, and record the pressure as the aortic root pressure after the pressure is stabilized.
Currently, the left ventricle and aortic root pressure monitoring generally comprises the following two methods: 1. the percutaneous puncture is inserted into a pigtail catheter from femoral artery or radial artery and runs reversely into the left ventricle to monitor the pressure of the left ventricle, then the catheter is withdrawn to the root of the aorta to monitor the pressure of the aorta, and the operation method has unreliable data; 2. meanwhile, a pigtail catheter is respectively placed in the left ventricle for pressure monitoring of the left ventricle through percutaneous puncture from a femoral artery path and a radial artery path, and the other catheter is used for pressure monitoring of the root of the aorta at the root of the aorta.
The above method, although simple, has many problems, including: 1. the left ventricular pressure monitored in method 1 is not synchronous with the aortic pressure (the two pressure monitoring are not in the same cardiac cycle), and obvious errors can exist in patients with arrhythmia; 2. in the method 2, the pressure can be synchronously monitored, but additional puncture is needed, so that the trauma of a patient is increased; the problem can be solved if there is a catheter to monitor the left ventricular and aortic root pressures simultaneously. There is currently no catheter available on the market for this function.
