A hybrid strategy, firstly performed in the 1990s, is a combination of tools available only in the catheterization laboratory with those available only in the operating room in order to minimize surgical morbidity and face with any cardiovascular lesion. The continuous evolution of stent technology along with the adoption of minimally invasive surgical approaches, make hybrid approaches an attractive alternative to standard surgical or transcatheter techniques for any given set of cardiovascular lesions. Examples include hybrid coronary revascularization, when an open surgical anastomosis of the left internal mammary artery to the left anterior descending coronary artery is performed along with stent implantation in non-left anterior descending coronary vessels, open heart valve surgery combined with percutaneous coronary interventions to coronary lesions, hybrid aortic arch debranching combined with endovascular grafting for thoracic aortic aneurysms, hybrid endocardial and epicardial atrial fibrillation procedures, and carotid artery stenting along with coronary artery bypass grafting...

Rapamycin is an immunosuppressive agent that is added to drug eluting stents. It prevents restenosis, but it also impairs reendothelialization. Nicorandil is a hybrid agent with adenosine triphosphated (ATP)-sensitive K+ (KATP) channel opener and nitrate properties. It prevents oxidative stress and cell apoptosis induced by rapamycin in endothelial cells in vitro. However, whether nicorandil promotes reendothelialization after angioplasty delayed by rapamycin remains to be determined. Balloon injury model was established in SD rats...

Hybrid stage I palliation combines cardiothoracic surgery and interventional transcatheter procedures for treatment of hypoplastic left heart syndrome. The approach is an alternative to the Norwood procedure, the traditional first stage of surgical palliation. Hybrid stage I palliation involves placing bilateral branch pulmonary artery bands and a patent ductus arteriosus stent through a median sternotomy, performed without cardiopulmonary bypass. The purpose of the bands is to control blood flow to the lungs and protect the pulmonary bed while the stent sustains systemic cardiac output...

A 48-year-old woman with 40 years of intermittent squeezing chest pain presented with worsening symptoms. Results of an ambulatory electrocardiogram, echocardiogram, and exercise treadmill were unremarkable. Persistent symptoms prompted a computed tomography coronary angiogram (CTCA) that revealed mid-left anterior descending artery myocardial bridging (MB) that was not physiologically significant by exercise single-photon emission CT. Conservative treatment was pursued. Anatomic MB is prevalent in a large proportion of the general population and are increasingly identified by CTCA...

BACKGROUND AND AIMS: Although fully covered self-expandable metal stents (FCSEMSs) have been commonly used for EUS-guided biliary drainage (EUS-BD), FCSEMSs migration is a main limitation of this procedure. In the present study, we evaluated the technical and clinical success rates, adverse events and long-term outcomes of a newly developed hybrid stent that has been customized for EUS-BD. METHOD: From September 2011 to May 2015, a total of 54 consecutive patients with biliary obstruction were enrolled in this prospective, observational study...

OBJECTIVE: Myocardial infarction (MI) continues to be a major burden of disease, despite rapid reperfusion interventions. Reperfusion of ischemic hearts (reperfusion injury) induces free radical generation, activation of early stress responses and apoptosis, which contributes to ventricular remodeling and dysfunction, which may lead to developing heart failure. Mineralocorticoid receptor (MR) antagonists have been shown clinically to reduce blood pressure, particularly in resistant hypertension, and substantially increase survival in heart failure...

Free esophageal perforation following a hybrid visceral debranching and distal endograft extension to repair a ruptured thoracoabdominal aortic aneurysm (TAAA) is a rare complication. The authors report a 56-year-old male who underwent elective thoracic endovascular aortic repair of a thoracic aneurysm. Four and a half years later, he presented with a new aneurysm extending from the distal end of the thoracic stent graft to the aortic bifurcation involving all the visceral arterial branches. The TAAA ruptured while he was awaiting an elective repair, and as a result, he underwent an emergency hybrid procedure...

An elderly man presented with fever and evidence of Salmonella infection, and was diagnosed to have coexisting constrictive pericarditis and mycotic aneurysm of the aortic arch. Pericardiectomy was performed under cardiopulmonary bypass with good result. To avoid deep hypothermic circulatory arrest, an aorto-brachiocephalic bypass, instead of total arch replacement, was performed. This was followed by a staged carotid-carotid bypass, thoracic endovascular stent graft placement. He was subsequently treated with prolonged antibiotics, and inflammatory marker normalized afterwards...

A 77-year-old man with a history of stent implantation in the right common iliac artery(CIA) and the left external iliac artery(EIA) was admitted to our hospital for a rapid growth of an aneurysm( max 53 mm) at Th11 level of the descending aorta. Although thoracic endovascular aortic repair (TEVAR) was required, there were many problems about access rout. The infrarenal abdominal aorta and the left EIA were severely calcified, and the lumens of the right CIA stent(5.3 mm) and the left EIA stent( 4.3 mm) were small in size...

We sought to describe the use and outcomes of small, medium and large premounted stents in patients with congenital heart disease, including incidence of and risk factors for re-intervention and development of in-stent stenosis. Premounted stents offer several advantages over traditional manually crimped bare-metal stents, especially in small patients. There are no data describing the medium-term effectiveness and outcomes of premounted stents in congenital heart disease. We performed a single-center retrospective review of all small, medium and large premounted stents implanted over an 8-year period...
