Abstract:

Introduction: half-year data on results of using new domestic NanoMed devices for closing atrial septal defects (ASD) were obtained. The occluder is a nitinol self-expanding and self-centering double disc device with a polyester membrane.

Aim: was to evaluate the safety and efficacy of a new domestic occluder for closing of atrial septal defect in a small group of patients over a 6-month follow-up period.

Material and methods: four pediatric patients underwent closure of atrial septal defects with domestic NanoMed occluders. Clinical examination and transthoracic echocardiography were performed at 24 hours, 1, 3, and 6 months. Endpoints included technical success of intervention, efficacy and safety of the procedure at follow-up instrumentation and physical examination.

Results: the average age of patients was 5,2 years (range 4 to 7 years). Mean ASD diameters and device waist sizes were 11,9 ± 1,2 mm and 13,7 ± 1,2 mm and 13,7 ± 1,2 mm, respectively. Technical and procedural success achieved in 100% of cases. During the six-month follow-up, no adverse events and residual flows were identified.

Conclusion: initial half-year data on the absence of adverse events and residual flows indicate the safety and effectiveness of the use of NanoMed occluders.

Abstract:

Chemodectomas are rare, in most cases, benign neoplasms. They originate from the chemoreceptor cells of the carotid glomus in the bifurcation of the carotid artery. Chemodectoma treatment is surgical. Classical removal of the tumor carries a high risk of damage of arteries and nerves. We present a case report of high localization (C1) carotid chemodectoma removal in a hybrid operating room. Tumor was successfully removed after selective embolization of chemodectoma with protection of distal flow of the internal carotid artery. This approach helped to minimize intraoperative blood loss, as well as to shorten time of intervention.

Abstract:

Currently, endovascular correction has become the method of choice in most cases of secondary atrial septal defects.

The obvious superiority lies in low trauma, a decrease in the incidence of early complications, atrial flutter and fibrillation, systemic thromboembolism, ischemic stroke, and all-cause mortality.

We present the initial experience of using new occluders for ASD closure.

Abstract:

Aim: was to determine the influence of blood plasma fibrinogen level on results of the left main coronary artery stenting.

Material and methods: clinical, laboratory and angiographic parameters of 819 patients after elective stenting of the unprotected left main coronary artery were used. The end-point was target lesion failure (TLF), including adverse events as repeated revascularization of the target lesion (TLR), myocardial infarction (MI) and death from cardiac causes.

Results: in 5 years follow-up period, end-point was achieved in 158 cases (19,3%). Independent predictors of TLF were: SyntaxScore > 32 (HR 1,089 95% CI 1,029-1,153, p = 0,003), creatinine level (HR 1,009 95% CI 1,004-1,013, p=0,001) and fibrinogen level (HR 1,4 95% CI 1,169-1698, p=0001). According to results of the Kaplan-Meier analysis, the cumulative probability of the TLF was higher in patients with fibrinogen values greater than 3,48 g/L (log-rank 0,001).

Conclusion: blood plasma fibrinogen level was an independent predictor of the TLF after left main coronary artery stenting. Increase in the level of blood fibrinogen for each 1 g/L led to an increase in the risk of TLF by 1,4 times per month.

Abstract:

Aim: was to study in-hospital results of high-risk percutaneous coronary intervention (PCI) with extracorporeal circulatory support.

Material and methods: a single center, retrospective study was performed in 49 adult patients undergoing high-risk PCI with mechanical circulatory support (cardiopulmonary bypass - CPB and еxtracorporeal membrane oxygenation – ECMO) performed in high-risk patients with acute coronary syndrome, multiple coronary lesions and impaired ejection fraction between 2011 to 2019. Mean age was 64,4±6,7 years. Previous myocardial infarction had 38(77%) patients, 18(37%) patients had a history of previous cardiac surgery. In 18(37%) patients, ejection fraction (Simpson) was less than 30%. Mean value of the left main (LM) artery stenosis was 74,6±8,9%, while combined with occlusion or subocclusion right coronary artery (RCA) in 38(77%) patients. Multivessel coronary lesion had 42(86%) patients (average SYNTAX Score was 42,1±11,5 points)

Results: 17 patients (35%) underwent high-risk PCI under preventional mechanical circulatory support with CPB. Myocardial infarction, strokes, stent thrombosis, limb ischemia, lethal outcomes were not observed in these patients. 7(14%) patients were admitted to the Cath Lab with myocardial infarction complicated by cardiogenic shock, in 3 patients – with pulmonary edema. 12(24%) patients after previous heart surgery were admitted to the Cath Lab after cardiopulmonary resuscitation on extracorporeal circulatory support, four of them (8%) with ongoing chest compressions. In 6(12%) patients, during CAG/PCI, critical hemodynamic instability was observed, induced by incurable cardiac arrhythmias required an emergency extracorporeal support. Average time of extracorporeal circulatory support was 128,62±92,4 min. Complications associated with CPB and ECMO were not observed. Two patients (4%) had stroke in the postoperative period. Hospital mortality was 17(34,7%) patients.

Conclusion: extracorporeal circulatory supports provide good life maintenance for high-risk PCI and an possibility for emergency PCI in extreme clinical situations.

Abstract

Introduction: article presents the first experience and long-term results of using domestic coronary balloon-expandable stents with a bioinert carbon coating, «Nanomed».

Aim: was to evaluate long-term results of using domestic coronary balloon-expandable stents with bioinert linear chain carbon coating (BLCCC), «Nanomed».

Materials and methods: the study included 387 patients, suffering from coronary heart disease, who underwent endovascular myocardial revascularization from 2016 to 2018, with implantation of coronary balloon-expandable stents with BLCCC by the Nanomed company, Penza. The control group included 320 patients who underwent endovascular myocardial revascularization with implantation of coronary balloon-expandable cobalt-chromium stents «MSure Cr» of the company «Multimedics», during the same period. A comparative estimation of long-term results was carried out on the basis of a study of the overall frequency of repeated myocardial revascularization; repeated interventions on the target vessel; the frequency of interventions on other coronary arteries with the progression of atherosclerosis; long-term survival rates.

Results: in the long-term period, the overall probability of absence of repeated revascularization in 47 months after PCI was 78,3 ± 2.1% and 72,1 ± 2.4% in the «Nanomed» BLCCC and «MSure Cr» groups, respectively. There was no statistically significant difference between groups (Log. Rank=0,77). However, the incidence of restenosis in the stent was statistically significantly higher in the «MSureCr» group. (p = 0,027). The overall probability of survival in 47 months after surgery was 98,2±2,4% and 98,1±2.6% in groups 1 and 2, respectively. No statistically significant difference between groups was found (Log. Rank=0,4).

Conclusions: 1. The use of a coronary balloon-expandable stent with a BLCCC, Nanomed for endovascular myocardial revascularization is an effective treatment in patients with coronary heart disease.

2. Long-term results of using bioinert carbon-coated stents, Nanomed and MSureCr stents were comparable in terms of absence of myocardial re-revascularization procedures due to relapse of the angina pectoris and survival time of up to 47 months. However, the incidence of restenosis in a stent with a bioinert carbon coating, Nanomed was statistically significantly lower.

Abstract

Aim: was to compare annual results of the use of stents with drug eluting - «NanoMed» and Orsiro.

Material and methods: in a randomized prospective study, an analysis of clinical and angiographic data of 1040 patients after stenting of coronary arteries with the observation period of 12 months was performed. The study and control groups randomly included 520 patients with implanted stents «NanoMed» and Orsiro.

Results: main initial clinical demographic and angiographic indicators did not statistically significantly differ. The primary endpoint (TLF - target lesion failure) was achieved in 6.5 and 5.9% in «NanoMed» and Orsiro groups, respectively (p = 0.7). Target lesion revascularization (TLR) was performed in study and control groups, respectively, in 1.7 versus 1.2% of cases (p = 0.4).

Conclusion: thus, in a comparative analysis of the use of stents «NanoMed» and Orsiro for a period of 12 months - no statistically significant difference was revealed.

Abstract:

Aim: was to identify risk factors of early adverse cerebral events after carotid artery stenting anc endarterectomy

Materials and methods: 908 patients who underwent isolated carotid stenting (N = 522) and carotid endarterectomy (N = 386) were included in this retrospective analysis. Patients with simultaneous cardiac surgery and patients with symptomic stenosis of CA were excluded from research. The primary end point was ipsilateral perioperative ischemic stroke, proved by neurologist and CT/MRI data. To identify predictors, multivariate regression was used, with factors that could influence endovascular and surgical methods of treatment.

Results: patients from two groups were similar in main clinical and demographic characteristics. There were no deaths and cerebral hemorrhagic complications. The stroke rate in the endovascular and surgical groups was 1.7% and 1.04% respectively (p = 0.5). The total rate of strokes and transitory ischemic attack (TIA) using two methods was 1.4%. The TIA rate was higher in the endovascular group without statistically difference (1.3% vs. 0.3%, p = 0.1). The regression analysis showed that predictor of the adverse cerebral events was the degree of carotid artery stenosis in endovascular group (OR 1.318, 95% CI: 1.131-1.535, p <0.001). There were no any predictive factors of TIA or stroke in the surgical group.

Conclusions: the independent predictor of early TIA and stroke in endovascular group, unlike endarterectomy, was the degree of carotid stenosis.

Abstract:

Aim: was to evaluate the safety and efficacy of coronary stents «MedEng» and to compare them with results of the use of other coronary stents.

Materials and methods: the study included 147 patients with coronary artery disease, which in the period from January to March 2014 underwent coronary stenting. Stents «MedEng» were implanted in 61 patients (group 1). The second group (control) consisted of 86 patients who underwent implantation of stents «Driver». Average follow-up was 6,2±0,5 months. Endpoints were: the return or retention of not less than 2 angina functional class (on CCS); death by cardiac causes, myocardial infarction (MI), repeated intervention on the target vessel, restenosis> 50%, confirmed by angiography and/or the data of optical coherence tomography (OCT)

Results: success rate of stenting was 100%. Death and MI during follow-up were not observed. Restenosis was observed in 9(14,7%) patients in group «MedEng» and in 13 (15,1%) patients from «Driver» group (p = 0,9). The average degree of coronary restenosis was 76,1±8,4% and 76,2±6,4% in the first and second groups, respectively (p=0.9). According to results of logistic regression, stents «MedEng» was not a predictor of restenosis (OR=1,998; 95% CI (0,158-312,551); p = 0,314).

Conclusions: the use of stents «MedEng» is safe and effective in myocardial revascularization. Results of implantation of stents «MedEng» do not different from results of the use of stents «Driver».
