The first experience of carrying out endovascular denervation of pulmonary trunk in the case of a patient having high pulmonary hypertension
The clinical example of effective denervation of the pulmonary trunk, using endovascular radiofrequency ablation. The patient Sh, male, 52 years with high secondary pulmonary hypertension with the background of persistent atrial fibrillation, chronic heart failure functional class 4 SOCS scale (11 points).Patient underwent coronary artery, bypass grafting mammarocoronary in 2006, stenting peredana descending artery in 2015 and implantation of a biventricular cardioverter defibrillator in 2014.Сurrently patient underwent radiofrequency ablation of His bundle and circular denervation of the pulmonary trunk. 3 months after procedure there was a significantly reduced systolic blood pressure in the pulmonary artery by 32% from initial values and a decrease in left ventricular volume. Severity of chronic heart failure, (SOCKS scale)decreasedfrom 11 points (4 functional class) to 7 points (3 functional class) after ablation. The technique of endovascular radiofrequency ablation ofpulmonary artery is easily reproducible, insignificantlylengthens the operation time.
