Ostial lesions present unique challenges for percutaneous coronary intervention (PCI). These lesions are often more calcified, fibrotic, rigid, and more prone to elastic recoil. Intervention on these lesions is associated with higher procedural complications and higher rates of restenosis. Ostial lesions require precise stent placement in the ostium with the absence of side branch compromise. Accurate stent placement in the ostium without side branch compromise is difficult to accomplish with angiography alone...

During transradial intervention, sharp edge of the guide catheter tip may act like a "razor-blade" and can prevent the catheter navigation especially in situation like double hair pin loop. Here, we report primary percutaneous coronary intervention (PCI) through diagnostic catheter using an innovative technique, balloon-assisted sliding and tracking (BLAST), to overcome this double hairpin loop, thus saving time and contrast volume.

AIM: To assess the long-term results of different approaches to treating patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) and multivessel coronary artery disease (MVCAD). SUBJECTS AND METHODS: A total of 150 patients with NSTE ACS, in whom coronary angiography revealed MVCAD, were examined. The patients were divided into 3 groups according to the selected treatment policy: 1) percutaneous coronary intervention (PCI) (n=91 (60.6%)); 2) coronary artery bypass grafting (CABG) (n=40 (26...

Incidents of broken balloon in a coronary vasculature during percutaneous coronary angioplasty are very rare. Such events in cath-lab may create panic and can be life threatening for patients. Hence, immediate retrieval of broken balloon becomes vital. Here, we report an unusual complication of broken balloon in the mid portion of the left anterior descending coronary artery, which had a calcified and totally occluded in-stent restenotic lesion. The broken balloon was retrieved successfully with no eventual complication using a simple catheter-assisted balloon-supported retrieval technique...

OBJECTIVES: This work reports the concept and the practical feasibility of Reversed Single String bifurcation stenting technique by demonstrating three in vitro cases. BACKGROUND: Provisional T stenting is the most used interventional technique to treat coronary bifurcation lesions. However, after main branch (MB) stenting, treatment of the side branch (SB) may become indicated to provide a good final result. Currently applied methods all have their structural limitations with respect to wall coverage, multiple strut layers, poor apposition rate...

AIMS: To demonstrate the feasibility of distal left transradial approach for patients in whom left radial access is preferred over right radial access for coronary angiography and interventions. This procedure is more convenient for the operator. For the right- handed patient, left radial access is more convenient because of the free use of the right hand after the procedure. In addition, this technique reduces the chance for radial artery occlusion at the site of the distal forearm. METHODS AND RESULTS: Coronary access via the left distal radial artery at the anatomical snuffbox allows comfortable positioning of the dorsal side of the patient's left hand near the right groin...

Intravascular ultrasound (IVUS) imaging provides two-dimensional (2D) real-time luminal and transmural cross-sectional images of intravascular vessels with detailed pathological information. It has offered significant advantages in terms of diagnosis and guidance and has been increasingly introduced from coronary interventions into more generalized endovascular surgery. However, IVUS itself does not provide spatial pose information for its generated images, making it difficult to construct a 3D intravascular visualization...

The aim of the present paper is to report trends in Portuguese interventional cardiology from 2010 to 2015. We studied data from the prospective multicentre Portuguese National Registry of Interventional Cardiology (RNCI) to analyse percutaneous coronary intervention (PCI) procedures and structural heart interventions from 2010 to 2015. A total of 73,977 PCIs and 780 transcatheter aortic valve implants were performed during the study period. Since 2010 there has been a 60% increase in PCI procedures and a twofold increase in primary angioplasty rates reaching 316 per million population...

In a ranking of the gross domestic product per capita in 2015, Belgium ranked 19th in the world according to the International Monetary Fun1d and the World Bank. It has a Human Development Index of 0.890, in which it is preceded by only 20 other countries in the world. This is, at least in part, due to a well-developed social security system on which all citizens can rely. Over the last 5-10 years, however, this system has come under increasing pressure. This has resulted in insufficient, incomplete and late reimbursement of all technologies that were introduced over the last ten years in the cathlab: intracoronary imaging techniques are not reimbursed at all, and FFR only to a vastly insufficient degree...

We sought to examine the impact of calcific deposits on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). The outcomes of 1,476 consecutive CTO PCIs performed in 1,453 patients (65.5 ± 10 years, 85% male) between 2012 and 2016 at 11 US centers were evaluated. Moderate or severe quantity of calcium was present in 58% of target lesions. Calcified lesions were more tortuous and more likely to have proximal cap ambiguity and interventional collaterals. PCI of moderately/severely calcified CTOs more often required use of the retrograde approach (54% vs 30%, p <0...

Early identification and treatment of the vulnerable plaque, that is, a coronary artery lesion with a high likelihood of rupture leading to an acute coronary syndrome, have gained great interest in the cardiovascular research field. Postmortem studies have identified clear morphological characteristics associated with plaque rupture. Recent advances in invasive and noninvasive coronary imaging techniques have empowered the clinician to identify suspected vulnerable plaques in vivo and paved the way for the evaluation of therapeutic agents targeted at reducing plaque vulnerability...

Failure to cross with a guidewire is the most common reason for failure of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). In cases of CTO PCI with no interventional collaterals, an intravascular ultrasound (IVUS)-guided parallel wire technique is usually the last-resort procedure. Failure of this technique sometimes causes enlarged subintimal space, resulting in procedure failure. We present a successful second attempt at left anterior descending artery CTO PCI with no interventional collaterals...

OBJECTIVES: This study sought to create a contemporary scoring tool to predict technical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) from patients treated by hybrid operators with differing experience levels. BACKGROUND: Current scoring systems need regular updating to cope with the positive evolutions regarding materials, techniques, and outcomes, while at the same time being applicable for a broad range of operators. METHODS: Clinical and angiographic characteristics from 880 CTO-PCIs included in the REgistry of CrossBoss and Hybrid procedures in FrAnce, the NetheRlands, BelGium and UnitEd Kingdom (RECHARGE) were analyzed by using a derivation and validation set (2:1 ratio)...

BACKGROUND: Coronary bifurcated lesions (CBL) represent a hot topic of interventional cardiology. Provisional stenting, i.e. implantation of a drug-eluting (DES) in the main branch followed by side-branch (SB) intervention in case of suboptimal SB result, represents the gold standard to treat the vast majority of CBL undergoing percutaneous coronary interventions (PCI). The best technique for bail-out SB stenting has not been established. Prospective randomized trials comparing different stenting techniques may help provide important insights regarding the best way to conduct PCI in patients with CBL...

A 78-year-old woman presented with acute inferior ST-segment-elevation myocardial infarction and complete heart block. Angiography revealed spontaneous coronary artery dissection (SCAD) of her right coronary artery. Given her ongoing instability, we proceeded to primary coronary intervention. A strategy of sealing the distal lesion edge followed by the proximal edge containing the intramural hematoma before placing a final stent to the midsegment was decided on (3-stent strategy). Our case represents the second such "sequential stent-sandwiching" report and provides a strategy for percutaneous coronary intervention in hemodynamically unstable patients with SCAD...

BACKGROUND: There are limited clinical records in the literature regarding aortic valve replacement in left ventricular assist device (L-VAD) patients. Previously we had two cases of severe aortic valve regurgitation in patients with L-VAD support treated with Corvalve prosthesis insertion and Amplatzer closure procedure. Both patients died a few days after the procedure from complications not related to the procedure itself. PATIENT HISTORY: The patient was a male with previous coronary artery bypass graft surgery in 2001 that was complicated with postischemic dilated cardiomyopathy with severe heart failure (ejection fraction [EF], 20%)...

BACKGROUND: Chronic dissection of the thoracic and thoracoabdominal aorta as sequela of a prior type A or B dissection is a challenging problem that requires close radiographic surveillance and prompt operative intervention in the presence of symptoms or aneurysm formation. Open repair of chronic thoracic and thoracoabdominal aortic dissection using deep hypothermia has been our preferred method to treat this complex pathology. The advantages of this technique include organ and spinal cord protection, the flexibility to extend the repair proximally into the arch, and the ability to limit ischemia to all vascular beds...
