Objectives: Transcatheter closure of a secundum atrial septal defect (ASD II) has become an effective alternative for surgical treatment. In this study we evaluated the correlation between the two-dimensional transoesophageal echocardiographic (2D TEE) sizing of ASDs and the actual diameter of occluders in patients undergoing device closure.
Methods: The records of 54 patients who underwent transcatheter ASD closure were reviewed. ASD characteristics and maximum defect diameter were evaluated using preprocedure 2D TEE images. Appropriate device size was determined by the balloon sizing method, which measures the balloon occlusive diameter (BOD) via TEE and fluoroscopy. ASD closure was performed under continuous TEE monitoring using the Amplatzer occluder in all patients.
Results: The mean of the TEE-derived maximum defect diameter was significantly lower than the mean of the BOD (17.8 ± 4.5 vs 22.1 ± 5.1 mm; p < 0.001) and the mean size of the implanted occluder device (17.8 ± 4.5 vs 23.3 ± 5.1 mm; p < 0.001). However, a good correlation was found between the TEE-derived defect size and the BOD (BOD = 0.898 × TEE defect size + 6.212, R = 0.824; p < 0.001) and between the TEE measurement and the final size of the implanted Amplatzer (device size = 0.928 × TEE defect size + 6.853, R = 0.822; p < 0.001).
Conclusion: 2D TEE may provide a good equation to predict the BOD or the size of the occluder device; however, further studies are needed to investigate whether it is feasible to perform transcatheter ASD occlusion without balloon sizing.

Aim To compare the results of primary percutaneous coronary intervention (PCI) for non-ST-segment elevation acute coronary syndrome (NSTE-ACS) in patients who recently recovered from COVID-19 with those not previously infected with SARS-CoV-2; to establish prognostic criteria for PCI complications, including stent thrombosis and restenosis (ST and SR) and progression of ischemic heart disease, and to determine ways to prevent them.Material and methods In 2021, middle-aged patients admitted to the Baku Central Clinical Hospital with a diagnosis of acute coronary syndrome who underwent urgent myocardial revascularization using percutaneous balloon angioplasty of the occluded coronary artery (CA) with implantation of a second-generation intracoronary drug-eluting stent were divided into two observation groups: the main group of 123 patients who had COVID-19 in the previous 6 months, and the control group of 112 patients who were not previously infected with SARS-CoV-2. The immediate results of PCI were assessed according to the TIMI scale; complications were assessed both clinically, by the incidence of severe complications (major adverse cardiovascular events, MACE), and angiographically, by the incidence of early and late ST and SR, and de novo stenosis that developed during the two-year observation period.

ObjectiveThis study aims to determine the outcomes of nickel allergic patients who underwent a trial of forearm arterial stenting with a nickel-based stent, with follow-up to assess for an allergic reaction. In the absence of adverse effects, patients had their intracranial aneurysm treatment with a nickel-based cerebrovascular device.MethodsA retrospective analysis was performed on patients who had an allergy to nickel, with an intracranial aneurysm who underwent treatment with a permanently implanted nickel-containing device.

Introduction: Randomised controlled trials comparing endovascular thrombectomy (EVT) to medical treatment in patients with medium vessel occlusion (MeVO) suggested neutrality or futility of EVT. We studied whether the size difference between thrombectomy device and the occluded vessel influenced MeVO outcomes.
Patients And Methods: This was a retrospective single-centre observational study comprising EVT-treated patients with occlusion of the M2 branch of the middle cerebral artery on digital subtraction angiography.

BACKGROUND Atrial septal defect (ASD) occluder devices present a novel approach for managing persistent gastric leaks following sleeve gastrectomy. While sleeve gastrectomy is effective, postoperative leak rates reach up to 3% in primary surgeries and exceed 10% in revisions, with management remaining complex and non-standardized. CASE REPORT This case report describes a 20-year-old Saudi woman who developed a gastric leak after laparoscopic sleeve gastrectomy.
