Embodiment

[0031] This example applies the new technology of radiofrequency ablation of hypertrophic obstructive cardiomyopathy under the guidance of interventricular septal modeling method to display real-time trans-aortic valve pressure. Only through three-dimensional catheter modeling, the position of interventricular septal hypertrophy can be accurately judged, with real-time display catheter ablation Whether the position is in the target area, real-time display of the pressure drop across the aortic valve, real-time evaluation of the ablation effect, real-time monitoring of normal conduction path damage, etc. And combined with the interventricular septum modeling method to guide the radiofrequency ablation of hypertrophic obstructive cardiomyopathy, it achieves high efficiency and saves medical expenses at the same time.

[0032] The method of this embodiment is as follows:

[0033] ① Connect the signal output ends of the pigtail catheter 1 and the pressure guide wire 2 of the syste...

Abstract

A system for displaying trans-aortic valve pressure in real time during interventricular septal ablation, which relates to the medical field. An issue where real-time data on pressure could not be automatically generated. The invention innovatively designs the same-machine interface of the pigtail catheter and the pressure guide wire, and the data of the supravalvular pressure and subvalvular pressure (left ventricular pressure) are displayed synchronously, which is more accurate and convenient. The pressure guide wire used in coronary pressure manometry is applied to ventricular manometry, which solves the difficulty that the pigtail catheter cannot simultaneously display and measure supravalvular and subvalvular pressure. The invention is applied in the field of interventricular septal ablation.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a system for real-time display of trans-aortic valve pressure in ablation of interventricular septum. Background technique [0002] The main pathological feature of hypertrophic obstmctive cardiomyopathy (HOCM) is that the thickening of the ventricular septum causes the stenosis of the left ventricular outflow tract (1eft ventricular outnowtract, LVOT), which in turn leads to a significant increase in the pressure gradient of the left ventricular outflow tract, which can cause Symptoms such as chest pain, chest tightness, fainting, and difficulty breathing. Studies have shown that the more severe the LVOT obstruction, the more obvious the clinical symptoms and the worse the prognosis. Hypertrophic cardiomyopathy can start at any age and is the first cause of sudden cardiac death in young people and one of the main causes of heart failure. The incidence of hypertrophic cardiomyopathy amo...
