Mathias Schlögl, Daniel Hofmänner, Robert Manka, Dagmar I Keller
We present a case of an 80-year-old Turkish female patient with diabetes who suffered an acute myocardial infarction (AMI) and underwent percutaneous coronary balloon angioplasty (PTCA)/stenting. Due to new ischaemic episodes, a second PTCA/stenting had to be preformed 6 days later, which revealed a partial restent thrombosis. This case report raises several important issues. First, language problems are an important barrier for safety and quality in healthcare. Second, gender, ethnicity and age differences in patients with AMI need to be considered in order to eliminate inequities in clinical practice...

In the early days of coronary angiography, the precise quantification of luminal narrowing was challenging. The introduction of balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA]) by Andreas Grüntzig in 1977 was perhaps the greatest incentive to the development of quantitative coronary angiography (QCA). QCA has played a crucial role in evaluating interventional techniques and assessing the results of new technologies. With the advent of drug-eluting stents (DES), QCA metrics such as late lumen loss and diameter stenosis (restenosis) proved to be instrumental in assessing new technologies...

BACKGROUND: The morphology and extensity of the stenotic lesion is crucial as well as the obstruction ratio. It is well known that the complexity of lesions has a direct impact on endovascular treatment (PTCA/stent); however, the arrangement of the lesions is underestimated and not well studied. AIM: We sought to evaluate the haemodynamic effects of different stenotic lesion models and arrangements in vitro. METHODS: Vascular circulation was simulated in vitro...

We present a case of rescue percutaneous coronary intervention (PCI) using right radial approach in a rare case of single coronary artery originating from the right sinus. Although these anomalies and stenosis of anomalous vessels have earlier been reported, treatment of atherosclerotic lesions by PCI has rarely been reported. There is a definite risk during PCI in patients with a single coronary ostium because dissection with the guiding catheter would result in a catastrophic event. Additionally, technical difficulties may occur due to the ostial configuration and course of the branch to be stented...

Cardiovascular diseases including atherosclerosis are a major financial and health burden globally. Inflammation associated with atherosclerosis results in the development of plaques that can rupture causing thrombosis, stroke, or death. The most widely used treatment for the removal of atherosclerotic plaques is percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Although this is a safer and minimally invasive method, restenosis and intimal hyperplasia after interventional procedure remains a major hurdle and more refined approaches are needed...

BACKGROUND: Iatrogenic acute ascending aortic dissection during percutaneous coronary intervention (PCI) is an exceptionally rare and life-threatening sequel that requires early and accurate diagnosis along with rapid management. No guidelines have yet been established to direct decisions on the different treatment options that can be employed in the setting of acute aortic dissections caused by PCI. However, similar cases have been treated either by intracoronary stenting and conservative management as in localized aortocoronary dissections or by surgical intervention in cases of extensive aortic dissections...

PURPOSE: Coronary artery disease involves the deposition of plaque along the walls of a coronary artery leading to narrowed or blocked vessels (stenosis) and is one of the main causes of death in developed countries. Percutaneous transluminal coronary angioplasty (PTCA) is used to reverse stenosis. Restenosis (renarrowing) of the treated vessel is a major complication of PTCA. A metal mesh tube (stent) can be placed inside the vessel to prevent restenosis. Tissue stress incurred during PTCA and stenting can provoke neointimal cell proliferation leading to in-stent restenosis (ISR)...

Primary percutaneous transluminal coronary angioplasty (PTCA) with the insertion of a stent is a well-established procedure for management of coronary artery disease. Infected pseudoaneurysms following PTCA and stenting are very rare and have poor outcomes if not managed properly. We are presenting a case of a man aged 50 years with infected pseudoaneurysm of the left anterior descending artery following multiple percutaneous interventions for coronary artery disease. In this paper, we have described the presentation, diagnosis and management of this patient and have discussed the aetiology and management options of infected pseudoaneurysm affecting coronary arteries...

BACKGROUND: In-stent restenosis and poor re-endothelization usually follow percutaneous transluminal coronary angioplasty, even using drug-eluting stents, due to inflammation and oxidative stress. Medical ozone has antioxidant and anti-inflammatory properties and has not been evaluated in this context. OBJECTIVES: To evaluate whether ozonotherapy might reduce restenosis following bare metal stents implantation in relation to the redoxin system in pigs. METHODS: Twelve male Landrace pigs (51±9kg) underwent percutaneous transluminal circumflex coronary arteries bare metal stent implantation under heparine infusion and fluoroscopical guidance, using standard techniques...

Cognitive behavioral therapy (CBT), established only a few decades ago, is widely used by clinical psychologists. This study aimed to investigate the effects of CBT on mental status and quality of life (QOL) after percutaneous coronary intervention (PCI) in young and middle-aged patients with coronary heart disease (CHD). Seventy-five anxiety/depression patients (mean age, 52.2 ± 6.2 years, including 8 individuals < 45 years old) with CHD treated with PCI were randomly divided into a CBT group (n = 38) and control group (n = 37)...

A number of cardiac fluoroscopic interventions have increased rapidly worldwide over the past decade. Percutaneous transluminal coronary angioplasty (PTCA) and stent implantation have become increasingly popular, and these advancements have allowed patients to receive repetitive treatments for restenosis. However, these advancements also significantly increase radiation exposure that may lead to higher cumulative doses of radiation. In the present study, a nationwide population-based case-controlled study was used to explore the risk of leukemia after cardiac angiographic fluoroscopic intervention...

BACKGROUND: Major adverse cardiovascular events (MACE) cause the leading cause of morbidity and mortality in patients with end-stage renal disease (ESRD) on maintenance Hemodialysis (HD) or peritoneal dialysis (PD). Many randomized-controlled trials (RCTs) have proved that angiotensin receptor blockers (ARBs) can reduce the risk of MACE in the people with normal or impaired kidney function without dialysis. This study seeks to clarify whether ARBs therapy could also attenuate this risk in patients with ESRD on maintenance dialysis...
