Peripheral artery disease (PAD) is a major health concern affecting more than 200 million people worldwide and studies have shown PAD to be a strong predictor of mortality, morbidity, and disability. The management of PAD is multi-tiered and advancements in technology have given physicians more options for endovascular revascularization if medical therapy does not result in substantial improvement. Many randomized controlled trials (RCT) have reported efficacy of various therapies including laser atherectomy, stent technology, and drug-coated balloons over standard percutaneous transluminal angioplasty; however, uncertainty regarding the best standard of care remains unclear due to a lack of head to head comparisons between novel therapies...

Coronary artery disease (CAD) is the leading cause of mortality and morbidity worldwide. Clinically, CAD can be potentially managed through surgical artery bypass. However, due to the highly invasive nature, surgical intervention has been gradually replaced by percutaneous transluminal coronary angioplasty and recently by percutaneous coronary revascularization using metallic stents. However, the permanent presence of metallic scaffolds inevitably impairs arterial physiology and may induce a variety of adverse effects, such as inflammation, restenosis, thrombosis, and neoatherosclerosis...

Percutaneous transluminal angioplasty (PTA) is now more frequently used to improve tissue perfusion in ischemic diabetic feet. However, there are concerns about its feasibility and effectiveness in severely ischaemic feet. This study aimed to compare the perfusion values after PTA according to the ischaemic degree of diabetic feet. This study included 133 ischaemic diabetic feet. The foot transcutaneous oxygen pressure (TcPO2 ) and toe pressure were measured before the procedure and every second postoperative week for 6 weeks...

INTRODUCTION: Percutaneous transluminal angioplasty (PTA) is often complicated due to postcontrast acute kidney injury (PC-AKI) in patients diagnosed with chronic kidney disease (CKD). Hydration therapy is the cornerstone in the prevention of PC-AKI. Furosemide forced diuresis with matched hydration using the RenalGuard system enables a steady balance between diuresis and hydration. A randomised controlled trial will be performed in order to investigate whether furosemide forced diuresis with matched hydration in combination with the RenalGuard system decreases incidence of PC-AKI in patients with CKD receiving a PTA of the lower extremities...

OBJECTIVES: Percutaneous transluminal angioplasty (PTA) requires the use of nephrotoxic contrast. Patients with chronic kidney disease (CKD) are more prone to develop contrast-induced-nephropathy (CIN) after utilization of contrast. Doppler ultrasound (duplex) guided PTA (DuPTA) is a novel technique and has recently proven to be a successful alternative to conventional PTA in the treatment of iliac stenotic disease, without the use of contrast. In this randomized controlled trial we evaluated whether duplex-guided PTA is as effective as conventional PTA in the treatment of iliac arterial stenotic disease...

REVIEW
John Canfield, Hana Totary-Jain
The field of interventional cardiology has evolved significantly since the first percutaneous transluminal coronary angioplasty was performed 40 years ago. This evolution began with a balloon catheter mounted on a fixed wire and has progressed into bare-metal stents (BMS), first-generation drug-eluting stents (DES), second- and third-generation biodegradable polymer-based DES, and culminates with the advent of bioabsorbable stents, which are currently under development. Each step in technological advancement has improved outcomes, while new persisting challenges arise, caused by the stent scaffolds, the polymers employed, and the non-selective cytostatic and cytotoxic drugs eluted from the stents...

BACKGROUND: Circulating endothelial cells (CEC) may be used to find new strategies for the early diagnosis of cardiovascular diseases. The major objective of the project is to broaden knowledge of CEC biology by determining their phenotypic characteristics. The additional aim is to clarify whether on the basis of these information it is possible to identify the origin of CEC release (from various cardiovascular compartments). METHODS: Circulating endothelial cells were collected from arterial blood prior to angiography, as well as from arterial and venous blood obtained after angiography/coronary angioplasty, from 18 patients with non-ST-segment elevation myocardial infarction (NSTEMI)...

We investigated the relationship of postoperative neutrophil-lymphocyte ratio (NLR) with 6-month primary patency of percutaneous transluminal angioplasty (PTA) in femoropopliteal disease using drug-coated balloon (DCB) or uncoated balloon (UCB). This retrospective study included 106 patients who received DCB (n = 44) or UCB (n = 62). The postoperative NLR was lower in the DCB group than that in the UCB group (2.60 vs 3.23; P = .004), and 6-month primary patency rate was significantly higher in DCB group than that in the UCB group (77...

Percutaneous transluminal coronary angioplasty and subsequent vascular scaffold implantation remains the prevalent invasive treatment of coronary heart disease. In-stent restenosis remained a problem with bare metal stents, until drug-eluting stents were introduced. The inhibition of the healing process by the antimitotic drug coating and the permanent metallic remnant can promote sub-acute and delayed stent thrombosis. Thus, the development of biodegradable stents emerged as a subject of research. Magnesium-based bioabsorbable devices can provide sufficient radial force in the acute phase of vessel-treatment and degrade thoroughly in aqueous environment, making them potential new candidates for vascular scaffold applications...

Pharmacomechanical thrombolysis (PMT) and percutaneous transluminal angioplasty (PTA) for the treatment of acute thrombotic prosthetic arteriovenous access (PAVA) are conventionally guided by radiography, which may cause radiation injury and requires the use of radiographic contrast media. The aim of the present study was to summarize our experience with ultrasound-guided PMT and PTA as an alternative to radiographic guidance. Between December 2012 and October 2016, 114 patients with acute thrombosis of PAVA were treated urgently with ultrasound-guided PMT and PTA to restore blood flow...

AIMS: Transradial access (TRA) has become a standard approach for cardiac catheterization. However, an obstacle to TRA is the risk of radial artery occlusion (RAO) after radial access in about 5%-10% of patients. We analyzed the safety and efficacy of getting vascular access after RAO by percutaneous transluminal angioplasty in cases of chronic radial occlusion. METHODS AND RESULTS: Chronic RAO was confirmed by Allen test and color Doppler in 8 patients. TRA was achieved by puncture in the distal tabatiere (anatomical snuffbox) using Seldinger's technique followed by insertion of a 5 Fr radial introducer sheath...
