Treatment of in-stent restenosis lesions, especially calcified with stent underexpansion, generally requires more complex techniques, such as rotational atherectomy. The case reported is a male patient 99% focal lesion at the origin first diagonal branch, where two stents were implanted 14 years ago. After failure balloon angioplasty alone, ablation plaque and part struts was performed using at...
AIMS We report the acute and 30 day results of the OPEN I study, a multicentre prospective single arm study evaluating the safety and feasibility of the Stentys bifurcation stent. METHODS AND RESULTS The Stentys stent is a provisional, self-expanding nitinol drug eluting or bare metal stent with small interconnections that can be disconnected by balloon angioplasty to provide access to the si...
The incidence of restenosis after a first successful percutaneous transluminal angioplasty of a native renal artery and the clinical and angiographic variables that may influence its occurrence were studied in 104 hypertensive patients. Angiograms obtained immediately before and after angioplasty and, in 92 patients, 8.8 +/- 6.0 months after angioplasty were interpreted separately by two observ...
We described a case of a 74-year-old man who suffered from acute coronary syndrome 7 years after coronary artery bypass grafting. The patient underwent angioplasty of the obtuse marginal branch of the left coronary artery from venous graft access, which did not result in relief of ailments. Only angioplasty of the narrowed subclavian artery caused an improvement in the patient's condition. The ...
Background & Aims: The aging of the population has caused an increase in the number of elderly people who receive treatment for cardiovascular disease. The prevalence of coronary artery disease is higher in the elderly, and on the other hand, complications after cardiac events are worse in the elderly. The most common cause of death in the elderly is cardiovascular disease. Rapid restoration of...
Background: Percutaneous Coronary Intervention (PCI) for bifurcated lesions is associated with a low rate of success and high rate of complications compared to such treatment of lesions of most other morphologies. Symptoms occurring at the time of procedure caused by PCI may require additional angiography with or without stenting through stent struts, which subsequently increases risks of reste...
A 35 year old woman with multiple pulmonary arterial stenoses and occlusions was admitted with increasingly severe breathlessness. Balloon angioplasty of a life threatening stenosis in a remaining pulmonary artery branch was attempted on two occasions but without success. When a self-expanding stainless steel stent was inserted at the site of stenosis after a further angioplasty acute localised...
The efficacy of 6 French guiding catheters for angioplasty of chronic total coronary occlusions was evaluated in 61 consecutive patients. The duration of the occlusion was determined angiographically, or estimated from an index clinical event. Endpoints were procedural success, defined as recanalization with less than 50% residual stenosis without major complications; and the need to change to ...
