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.

Silicone Polymer

Corrosion casts of the pulmonary trunk and major branches of the pulmonary arteries of 39 rabbits were made from a silicone polymer. In half of the rabbits the casts were made with the lungs expanded and half with the lungs collapsed. The length of various segments of the casts were measured from magnified photographs. It was found that in rabbits less than 23 days old the pulmonary trunk is significantly longer when the lungs are expanded than when they are collapsed. This suggests that a repeated longitudinal extension of the vessel occurs during breathing. This effect disappears after 30 days of age, possibly because of elastin fragmentation. Between the ages of 23 and 30 days the growth in length and diameter of the pulmonary trunk undergoes a rapid acceleration. This may also be the result of elastin fragmentation. Whereas it may be that repeated longitudinal stress in the pulmonary trunk during breathing causes elastin in its media to fragment, one cannot exclude the possibility that other factors such as growth are responsible.

Abstract Pulmonary embolism is one of the leading causes of maternal mortality despite a low incidence of during pregnancy. We present 32-year-old woman, in the 35 week of first pregnancy, admitted to the Intensive Care Unit with dyspnea, tachycardia, cyanosis. Echocardiography confirmed the presence of embolic material in the main trunk of pulmonary artery, spreading to the right pulmonary artery. D-dimer and troponin T level were elevated, BNP remained within the normal range. The risk in PESI scale was assumed as intermediate high. LMWH therapy was initiated, the patient was constantly monitored. Venous thrombotic disease in lower extremities was excluded by ultrasonography. The treatment was carried out under obstetric supervision. The clinical state gradually improved, the patient was hemodynamically stable. Serial echocardiographic testing, revealed gradual regression of changes in the pulmonary trunk. Normalization of troponins and lowering of BNP levels were observed. The pregnancy was terminated in 39 week, by cesarean section (obstetric indications). The LMWH was continued few days after delivery, as the patient started lactation. She decided to terminate lactation in a first week after delivery so the therapy was switched into rivaroxaban for at least 3 months. Echocardiography after 3 month confirmed lack of changes in pulmonary trunk, the risk of pulmonary hypertension was low. Echocardiography can be a method of choice for confirming and monitoring pulmonary embolism during pregnancy, in a situation of high or intermediate clinical risk and good visualization of changes in pulmonary arteries Abstract P701 Figure.

Feodor Lynen died on 6 August 1979 of complications following an operation six weeks before for the repair of an aneurism of the abdominal aorta. Until then he had been fit. The aneurism, of which he had had no symptoms, had come to light when Lynen had been in hospital for a minor operation on his hand, treatment of a Dupuytren contracture, and a general medical check before the planned operation revealed the possibility of an aneurism. A specialist confirmed the diagnosis and suggested surgical treatment. Lynen accepted the advice without hesitation because one of his elder brothers had died of a ruptured aneurism a few years earlier. Lynen’s operation took place on 25 June and was at first thought to have been successful, but complications developed and he became seriously ill. Lynen was one of the outstanding biochemists of his generation and made many highly original discoveries. His intellectual brilliance was combined with an exceptionally attractive, warm-hearted and open personality and with a tremendous zest for life. Students at all levels (especially postgraduate students) and from all over the world, flocked to his laboratory, which became one of the great international centres of biochemistry.
