INTRODUCTION: The aim of our study was to assess the role of ECG-gated coronary CT angiography (CCTA) in the diagnosis, imaging follow-up, and treatment guidance in post-procedural/surgical interventions in the heart and thoracic aorta (PTCA, TAVI, PMK/ICD placement, CABGs). MATERIALS AND METHODS: We retrospectively evaluated 294 ECG-gated CCTA studies performed in our center from January 2020 to January 2023. CCTA studies were acquired to detect/exclude possible complications related to the endovascular or surgical procedure...

Interventional cardiologists in everyday practice are often confronted with calcified coronary lesions indicated for percutaneous transluminal coronary angioplasty (PTCA). PTCA of calcified lesions is associated with diverse technical challenges resulting in suboptimal coronary stenting and adverse long-term clinical outcomes. Angiography itself offers limited information regarding coronary calcification, and the adjuvant use of intracoronary imaging such as intravascular ultrasound (IVUS) and Optical Coherence Tomography (OCT) can guide the treatment of calcified coronary lesions, optimizing the different stages of the procedure...

Takayasu arteritis (TA) is now recognized worldwide and is a disease that mainly affects the aorta and its main branches. TA rarely involves the small or medium-sized vessels. Certain vascular lesions, such as arterial stenosis, occlusion, and aneurysm are common with TA. However, patients with new-onset TA who present with left main trunk acute non-ST segment elevation myocardial infarction are extremely rare. We report a 16-year-old female patient with non-ST segment elevation myocardial infarction due to severe stenosis of the left main coronary artery that was caused by TA...

Supersaturated oxygen (SSO2 ) is one of the emerging therapies that has shown benefit for patients suffering from acute ST elevation myocardial infarction (STEMI) in terms of reducing infarct size, which has been used as a prognostic indicator for future heart failure and hospitalizations. Trials investigating SSO2 therapy have shown improvement in infarct size when used as an adjunct therapy to percutaneous trans-luminal coronary angioplasty (PTCA) or percutaneous coronary intervention (PCI) in patients presenting with acute myocardial infarction (aMI)...

Introduction This prospective observational study reports the association between baseline high-sensitivity C-reactive protein (hs-CRP) levels and adverse events at six months in patients who were diagnosed with symptomatic chronic stable angina and then underwent percutaneous transluminal coronary angioplasty (PTCA) with a drug-eluting stent (DES). Methods A total of 104 patients were examined with chronic stable angina over a period of six months. Before conducting percutaneous coronary intervention (PCI), the baseline levels of hs-CRP were measured, and based on the levels, the patients were grouped into high and low hs-CRP groups...

The aim of this report is to explore the direct and long-term outcome in a high risk patient who was treated with rotational atherectomy (RA) to assist the placement of drug eluting stents in heavily calcified lesions. The patient presented with acute STEMI and had severely calcified Left main stem (LMS) disease, requiring plaque modification before coronary angioplasty and stent implantation. As the patient was elderly, with multiple comorbids including a number of coronary interventions, a decision of conservative management was made...

BACKGROUND: Drug eluting stents (DES) are associated with a 2% to 4% annual rate of target lesion failure through 5-to-10-year follow-up. The presence of a metallic protheses is a trigger for neo-atherosclerosis and very late stent thrombosis. A "leave nothing behind" strategy using Drug Coated Balloons has been suggested; however, paclitaxel coated balloons are only recommended in selected indications. Recently a novel sirolimus eluting balloon, the SELUTION SLR TM 014 PTCA balloon (SEB) (M...

BACKGROUND: Left ventricular thrombus (LVT) is a well-recognized complication of myocardial infarction (MI) in patients with diabetes. An embolic complication caused by LVT is a key clinical problem and is associated with worsened long-term survival. CASE PRESENTATION: A 45-year-old man with persistent left abdominal pain for 1 week and left leg fatigue was admitted to the emergency department. The cause of abdominal pain was embolism of the renal artery, the splenic artery, and the superior mesenteric artery caused by cardiogenic thrombosis, which further led to splenic infarction and renal infarction...

With the development of modern materials science, life science and medical science, the application of implant materials in clinical medicine is becoming more and more widespread. Vascular stent is an indispensable medical implantation device for the PTCA (Percutaneous Transluminal Coronary Angioplasty). However, the persistent inflammatory response after coronary stent implantation is one of the important reasons for in-stent neo-atherosclerosis (ISNA). This article starts with the current inflammatory problems caused by coronary stent implantation and discusses the formation mechanism of foam cells and key role of foam cells in the formation of atherosclerotic lesions...

Percutaneous transluminal coronary angioplasty (PTCA) has been accepted as the elective treatment in many patients with coronary atherosclerotic obstruction. A slight increase in cardiac markers after the percutaneous coronary intervention (PCI) has been commonly reported. Some researchers have suggested that it predicts mortality and long-term complications. This study aimed to evaluate the occurrence of increased postoperative cardiac enzymes and determine the relationship between such an increase and clinical angiographic and technical variables...
