Percutaneous transluminal angioplasty and stenting is becoming increasingly the first line treatment for patients with both claudication and critical limb ischaemia instead of surgery, with the aim of returning the patient's quality of life in the former and preventing amputation. Drug eluting technologies have seen a large surge in popularity in recent years, and significant patient benefits have been seen with the use of drug eluting stents and balloons over the use of plain balloon angioplasty. Unfortunately in many patients with arterial disease there is significant vessel wall calcification - this can theoretically be a barrier to drug delivery, and can also be a contributing factor to flow limiting dissection and the subsequent need for bail out stenting...

Background: Residual false channel is common after repair of type A acute aortic dissection (TAAAD). Starting from our recent series of TAAAD patients we carried out a retrospective analysis, regarding the failure of primary exclusion at the time of the initial operation. We classified the location of the principal entry tears perfusing the residual false channel. The proposed technique represents our attempt to correct the mechanism of false channel perfusion during primary repair. We describe a new technique designed to address some limitations of standard hemiarch aortic replacement...

BACKGROUND: Coronary involvement in aortic dissection heralds a poor outcome. Involvement of the left main stem may lead to left ventricular (LV) failure requiring mechanical circulatory support. CASE REPORT: A staged approach was applied in a 24-year-old female who suffered extensive infarction due to aortic dissection with left main stem involvement. After replacement of the ascending aorta and grafting of the left internal thoracic artery to the left anterior descending artery following a failed attempt at reconstruction of the left coronary ostium, she failed to wean from cardiopulmonary bypass (CPB) and underwent implantation of an extracorporeal life support (ECLS) system as a bridge to decision...

OBJECTIVES: This study aims to report mid-term follow-up outcomes of a series of TAAD patients treated with TEVAR in China. BACKGROUND: Thoracic endovascular aortic repair (TEVAR) has been used to treat type A aortic dissection (TAAD) for years. However, by comparing public reports, their outcomes which were based on different sample sizes show inconsistency. METHODS: Between January 2001 and December 2015, there were 56 patients with TAAD received TEVAR identified in 5 medical centers...

Catheter-induced aortic dissection during coronary angiography and Percutaneous Coronary Intervention (PCI) is a relatively infrequent, but potentially life-threatening complication. Patients who suffer this complication may require emergency aortic surgery. More recently, reports of treating the ostium of the dissected coronary artery have emerged as an alternative therapeutic option. In this article we describe two cases of extensive guide catheter induced dissection and their successful treatment using PCI and provide a concise overview of the available literature...

We are reporting a case of a 65-year-old female who experienced three ST elevation myocardial infarctions (STEMI) during the course of 3 weeks. The first infarct was related to intramural coronary hematoma that propagated proximally after stenting, the second involved progression of this hematoma with obstruction of the vessel lumen, and the third caused subacute stent thrombosis that required "stent cleaning" using the inflated balloon technique.

The RANK (receptor activator of nuclear factor κB)/RANKL (RANK ligand)/OPG (osteoprotegerin) axis is activated after myocardial infarction (MI), but its pathophysiological role is not well understood. Here, we investigated how global and cell compartment-selective inhibition of RANKL affects cardiac function and remodeling after MI in mice. Global RANKL inhibition was achieved by treatment of human RANKL knock-in (huRANKL-KI) mice with the monoclonal antibody AMG161. huRANKL-KI mice express a chimeric RANKL protein wherein part of the RANKL molecule is humanized...

BACKGROUND: The no-reflow phenomenon is a serious complication after primary percutaneous coronary intervention (PCI) for ST-elevation Myocardial Infarction (STEMI). Coronary artery ectasia (CAE) may increase the risk of no-reflow, however, only limited data is available on the potential impact of CAE. The aim of this study was to determine the potential association between CAE and no-reflow after primary PCI. METHODS: A case control study was performed based on a prospective cohort of STEMI patients from January 2000 to December 2011...

BACKGROUND: Femoral arterial access (FAA) during diagnostic coronary angiography (CAG) and percutaneous coronary interventions (PCI) are associated with several vascular complications (VC). VC rate in our experience a decade ago was 3.02% and higher in women (4.7% in women, and 1.67% in men, p < 0.0006), with an OR of 2.81 (95% CI: 1.51-5.22). METHODS: Patients who underwent CAG and PCI utilizing FAA (n = 2617) were separated into Period 1 (2005 to 2008; 1970 patients; Male 1045; Female 925) and Period 2 (2016-2017; 647 patients; Male 357; Female 290)...

BACKGROUND: Because of the challenges in treating calcified coronary artery disease (CAD), lesion preparation has become increasingly important prior to percutaneous coronary intervention (PCI). Despite growing data for both rotational atherectomy (RA) and orbital atherectomy (OA), there have been no multicenter studies comparing the safety and efficacy of both. We sought to examine the clinical outcomes of patients with calcified CAD who underwent atherectomy. METHODS: A total of 39 870 patients from five tertiary care hospitals who had PCI from January 2011 to January 2017 were identified...

Spontaneous coronary artery dissection is an increasingly recognized nonatherosclerotic cause of acute coronary syndrome. Reports regarding the prognosis and natural history of this disease are limited. In addition to the diagnostic difficulty, this condition poses a significant therapeutic challenge due to the lack of specific management guidelines. We present here a case series of 9 patients with spontaneous coronary artery dissection. Additionally, this article reviews the incidence, clinical characteristics, risk factors, diagnostic modalities, therapeutic approaches, and patterns of recurrence in patients with spontaneous coronary artery dissection...

A 22-year-old man with spontaneous coronary artery dissection wanted to assess the feasibility of returning to competitive cycling. He was referred to the cardiac rehabilitation (CR) program at Baylor Hamilton Heart and Vascular Hospital where staff designed a high-intensity, sport-specific training program that simulated the movements and forces associated with his goal activity. The program was symptom limited and enabled the patient to train earlier and at a higher intensity than is typically allowed in conventional CR programs...

RATIONALE: Left main shock syndrome (LMSS) induced by thrombosed coronary artery dissection is very rare and has a fatal prognosis. Optimal treatment strategy includes early reperfusion and hemodynamic support to prevent cardiogenic shock. However, it involves the extension of technical difficulties under different conditions. PATIENT CONCERNS: A 49-year-old woman developed symptoms of left main shock syndrome. The main clinical manifestations were retrosternal pain radiating to his back and left shoulder, heavy sweating, palpitation and brachypnea...

INTRODUCTION: Thoracic endovascular aortic aneurysm repair (TEVAR) is an established treatment for thoracic aortic disease in both the acute and elective setting, with such a widespread use that almost 50% of all thoracic aortic surgery in Europe is performed by these means. Nonetheless, the feasibility of TEVAR is determined by several anatomic factors, and the suitability of the proximal and distal landing zones remain one of the main limitations to its use. The advent of custom-made thoracic stent grafts widened the endovascular options in some challenging anatomies...

Urgent cardiothoracic surgical intervention for the management of complications of percutaneous coronary intervention is uncommon in the stent era. Nonetheless, given increasing procedural complexity, in part reflecting an aging population, an ongoing hazard for urgent surgery remains. We sought to review the incidence and outcome of urgent cardiothoracic surgery in patients undergoing PCI in a contemporary cohort at a tertiary referral centre. The incidence of cardiothoracic intervention for PCI related complications was low at 0...
