Aim. To analyze the dynamics of echocardiographic parameters after surgical treatment of severe pulmonary hypertension in patients with mitral valve disease and atrial fibrillation.Material and Methods. Data of surgical treatment in 202 patients with mitral valve disease complicated by severe pulmonary hypertension with blood pressure more than 40 mm Hg and atrial fibrillation were analyzed. Surgical intervention in these patients consisted in surgical correction of mitral dysfunction with artificial prosthetic valve or valve-preserving intervention (group 1, n = 62). In patients of group 2 (n = 89), correction of mitral valve defect was also performed as well as the Maze IV procedure for concomitant atrial fibrillation using bipolar radiofrequency ablator AtriCure. Patients of group 3 (n = 51) underwent integrated surgery, which consisted in the elimination of mitral valve defect, surgical correction of atrial fibrillation by Maze IV procedure, as well as circular radiofrequency denervation of the trunk and mouth of the pulmonary arteries (pulmonary artery denervation (PADN)).Conclusions. The circular PADN procedure was effective and safe, significantly reduced the level of pulmonary hypertension in the postoperative period (p = 0.018), and promoted reverse remodeling of the heart cavities. Integrated surgical correction in patients with mitral dysfunction, atrial fibrillation, and severe pulmonary hypertension may significantly reduce the phenomenon of heart failure (p = 0.023). Further analysis of the effectiveness of radiofrequency denervation of pulmonary arteries with the study of a larger number of patients, analysis of long-term results, as well as determining the possibility of this technique in patients with non-valvular forms of pulmonary hypertension are required.

Ventricular Afterload

Severe pulmonary hypertension (PH) can be a critical problem during and after cardiac surgery, since it increases right ventricular afterload resulting in decreased cardiac output. A case of pulmonary hypertension associated with mitral valve disease and resistant to glyceryl trinitrate therapy during surgery is reported. The case was treated successfully with prostaglandin E1 (PGE1), indicating that PGE1 can be used peri-operatively in a patient with refractory PH resistant to glyceryl trinitrate treatment.

Objective Investigate the influence of the sympathetic denervation of the pulmonary trunk and the orifices of the pulmonary arteries on the degree of pulmonary hypertension (PH) and outcomes of the surgical treatment of atrial fibrillation (AF) in patients with mitral valve defects, complicated AF, and high PH.Material and methods We analyzed the surgical treatment of 140 patients with mitral valve defect, concomitant AF, and high PH – pulmonary artery systolic pressure (PASP) gradient more than 40 mm Hg. The group of interest included 51 patients (46 patients with severe mitral stenosis and five patients with grade 4 mitral valve regurgitation). All patients underwent mitral valve correction (47 valve replacement surgeries and 4 valve-sparing interventions), biatrial Maze IV procedure, and additionally, denervation of the pulmonary trunk and the orifices of the pulmonary arteries. The control group included 89 patients diagnosed with mitral valve defect, AF, and PH with PASP > 40 mm Hg. However, unlike in patients of interest, denervation of the pulmonary arteries was not performed.Results Circular radiofrequency denervation of the pulmonary trunk and the orifices of the pulmonary arteries using a clamp-destructor is an effective and safe method, significantly reduces secondary PH (p=0.018), promotes reverse remodeling of the heart chambers, left atrium in particular (p=0.01), and improves outcomes of the Maze IV procedure (p=0.022) by restoring sinus rhythm in patients with mitral valve defects, complicated AF, and high PH.Conclusion This technique must be studied further involving a more significant number of patients, analyzing long-term results, and using this technique in patients with non-valvular causes of secondary PH.
