Background: Percutaneous closure (LAAC) of the left atrial appendage (LAA) is an efficacious preventive procedure for patients with non-valvular atrial fibrillation (NVAF) and considerable bleeding risk. We sought to systematically review the available LAAC data on the novel occluder device LAmbre™. Methods: For this systematic review, a search of the literature was conducted by 3 independent reviewers, reporting the safety and therapeutic success of LAAC in patients being treated with a LAmbre™. Publications reporting the safety and therapeutic success of LAAC using LAmbre™ in n > 5 patients were included. Results: The literature search retrieved n = 10 publications, encompassing n = 403 NVAF patients treated with a LAmbre™ LAAC, with relevant data regarding safety and therapeutic success of the procedure. The mean CHA 2 DS 2-VASc Score was 4.0 + 0.9, and the mean HAS-BLED score was 3.4 + 0.5. The implantation success was 99.7%, with a mean procedure time of 45.4 ± 18.7 min, and a fluoroscopy time of 9.6 ± 5.9 min, and a contrast agent volume of 96.7 ± 0.7 ml. The anticoagulation regimen was switched to DAPT post procedure in the majority of the patients (96.8%). Partial and full recapture were done in 45.5% and in 25.6%, respectively. Major complications were reported in 2.9%, with 0.3% mortality, 1.7% pericardial tamponade, 0.3% stroke, and 0.6% major bleeding complications; no device embolization was observed. During follow up at 6 or 12 months, major adverse cardiovascular events were reported in 3.3%: Stroke or TIA in 1.7%, thrombus formation on the device in 0.7%, and residual flow > 5 mm in 1.0%. In some publications, the favorable implantion properties of the LAmbre™ for difficult anatomies such as shallow or multilobular LAA anatomies were described. Conclusions: This systematic review on the LAmbre™ LAA-occluder including n = 403 NVAF patients demonstrates an excellent implantion success rate, promising follow-up clinical data, and favorable properties for also challenging LAA anatomies,. While its design seems to be helpful in preventing device embolization, pericardial tamponade may not be substantially reduced by the LAmbre™ as compared with other established LAAC devices. Further larger prospective multicenter registries and randomized trials are needed to scrutinize the value of the LAmbre™ compared with established LAAC devices.

The purpose of this study is to investigate incidence of gastrointestinal symptoms and complications in patients who underwent high-power short-duration (HPSD), posterior left atrial wall isolation during atrial fibrillation ablation and thereafter have received gastrointestinal prophylactic regimen consisting of sucralfate, proton-pump inhibitor and colchicine. Patients were followed and assessed at baseline, up until 6th month following the procedures.Among 115 patients who were included, 5 patients (4.3%) reported gastrointestinal symptoms at follow-up. No complications were diagnosed during the follow-up. In conclusion, the HPSD along with prophylactic regimen has been associated with low incidence of gastrointestinal adverse events.

Introduction Testis tumors constitute 1-2% of all malignant tumors in men. But it is the most common solid tumor in men between 15-35 years of age. Germ cell tumors constitute for almost 90% of all testis tumors. Intracardiac metastasis of testicular carcinomas is rare. We now report a case of a testicular germ cell tumor with right atrial metastasis. Case report A 30-year-old male patient was diagnosed with B-cell ALL.Chemotherapy and radiotherapy were completed in 2016. In January 2017, the patient applied to the hospital with pain in the right testicle.A mass detected and orchiectomy was performed.Pathologic examination revealed mixed germ cell tumor and B-cell ALL infiltration.Chemotherapy was started. The patient was admitted to our hospital with fever, in March 2018.Antibiotics were started but fever contuniued.Transthoracic echocardiography showed a large,hypoechogen,mobile mass in the right atrium.Then transesophageal echocardiography revealed a 2x3,3 cm mobile mass within the right atrium that prolapsed through the tricuspid valve into the right ventricle in diastole.We could not distinguish if it is a vegetation or a metastatic mass. The patient underwent cardiac surgery.Pathologic examination revealed mixed germ cell tumor metastasis. After the surgery, the patient was transferred to the intensive care unit because of sepsis. Antibiotics were expanded due to fever. Control transthoracic echocardiography and also transesophageal echocardiography showed a 1,8 x 0,6 cm mobile mass extending from the inferior vena cava into the right atrium and through the patent foramen ovale into the left atrium. One week after the surgery, a mass was detected in the transthoracic echocardiography. But no further examination was done. We thought that the mass may not have been completely removed in the the operation (residual tumor?). The patient was evaluated with the department of oncology and cardiovascular surgery. It was decided that reoperation would be very risky. Conclusion Metastatic tumors of the heart are seen more frequently than primary tumors. Although intracardiac metastasis of testicular germ cell tumors are rare (less than %1), it has been related to short survival. They may lead to the congestive heart failure, paradoxical systemic emboli and vena cava superior syndrome. Most cases in the literature are associated with right atrial mass. But in our case, the mass was extending from the inferior vena cava into the right atrium and through the patent foramen ovale into the left atrium. We wanted to share our experience and also wanted to discuss the treatment modality for similar patients. Abstract P1703 Figure.

Introduction Primary cardiac tumors are extremely rare; the incidence is approximately 0.001% to 0.03%. Malignant tumors account for 25% of primary cardiac tumors, and among those, sarcomas are the most prevalent. We report a case of primary cardiac sarcoma presenting with dyspnea due to mitral valvuler obstruction. Case Report A 41-year-old woman was admitted to the hospital with dyspnea for 8 months without any obvious causes. She was healthy previous and without family history. Physical examination was normal. Thorax computed tomography (CT) scan was performed with the doubt of pulmonary disease. A 1x1 cm hypodense nodule was detected in superior segment of the right lower lobe lung. Positron emission tomography-computed tomography (PET-CT) revealed a 1*1 cm nodule in the lung. And also increased 18F-fluorodeoxyglucose uptake was observed in the left scapula, left iliac wing and right 4th rib, likely due to metastasis. Biopsy from the lesion of iliac wing was performed. Pathologic examination was primarily compatible with the malign mesenchymal tumor and sarcoma infiltration; but malignant epithelial tumor and metastasis of carcinoma could not be ruled out. Magnetic resonance imaging of the lung was performed to find the origin of the metastatic tumor. A 8,6 x 5,3 x 5,1 cm mass filling the right and left atria was detected.It was extending from the right atrium to the superior vena cava and also from the left atrium to the right inferior and superior pulmonary venules. The image of mass was compatible with sarcoma. Transthoracic echocardiography was performed. A mass in the left and right atrium was detected. It was filling the left atrium. Due to the mass, the maximum mitral gradient was 21 mm Hg and the mean mitral gradient was 10 mm Hg, as if there was mitral stenosis.Systolic pulmonary artery pressure was 40 mmHg. Mild mitral insufficiency was detected. The patient was evaluated with the department of oncology and cardiovascular surgery. It was decided that the mass was inoperable. So transesophageal echocardiography was not performed. It was thought that, the mass was primary cardiac sarcoma, pulmonary nodule and bone lesions were metastasis of this primary cardiac sarcoma. So chemotherapy protocol (ifosfamide,adriamycin,mesna) was started. Conclusion Cardiac tumors have many clinical presentations. Early stages of the disease are often asymptomatic. In advanced stages, patients present with symptoms of the classic triad (intracardiac obstruction, systemic embolization, constitutional symptoms) Symptoms are often non-spesific; so diagnostic suspicion is very important. Although cardiac sarcoma therapy includes complete surgical excision, followed by radiotherapy and chemotherapy, prognosis is still poor. Surgery can offer dramatic palliation of symptoms in cases of valvular obstruction. In conclusion, it remains clear that early diagnosis and treatment are extremely important because of their prognostic and therapeutic value. Abstract P1697 Figure.

The issue of creating a favorable tax environment in any country plays an important role in solving the problem of human resource development. Foreign investors are more interested in the stability and evolution of the tax system, which allows them to predict their activities in the long run, rather than tax benefits and privileges. The main purpose of the state investment policy is to ensure the renewal of fixed assets and the reconstruction of production through the application of scientific and technical achievements. The formation of a favorable investment climate, the effective use of attracted domestic and foreign investment resources in the priority areas of the national economy is one of the urgent problems of the Azerbaijani economy. Enterprises become increasingly aware that proper investment into human resources can have a significant impact on their performance, which of course also affects their competitiveness. The corporate culture exactly offers the greatest source of competitive advantage of enterprises. Continual adaptation to changing market conditions attracts businesses to invest their energy and finance to staff by improving their competencies.
