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...

BACKGROUND: Laparoscopic surgery has begun to replace a great number of procedures that were previously practiced using open or conventional techniques. This is due to the minimal invasion, small incisions, and short time recovery. However, it has come to knowledge, that the increase in intra-abdominal pressure due to carbon dioxide pneumoperitoneum during laparoscopic surgery causes cardiovascular, respiratory, endocrine, and renal alterations. OBJECTIVE: To evaluate the nephroprotective effect of telmisartan, an angiotensin II AT1 receptor antagonist, on glomerular filtration in laparoscopic surgery...

PURPOSE OF REVIEW: With continued optimization of islet isolation and immunosuppression protocols, the medium-term rates of insulin independence following islet transplantation have improved significantly. This review evaluates the most up-to-date outcomes data for both solid organ pancreas and islet transplantation to develop an algorithm for selection of β-cell replacement in type 1 diabetes patients. RECENT FINDINGS: Solid organ pancreas and islet transplantation have both displayed improved rates of 5-year insulin independence, largely attributable to improvements in immunosuppressive regimens...

The past several decades have witnessed major advances in the understanding of the structure, function, and biology of native valves and the pathobiology and clinical management of valvular heart disease. These improvements have enabled earlier and more precise diagnosis, assessment of the proper timing of surgical and interventional procedures, improved prosthetic and biologic valve replacements and repairs, recognition of postoperative complications and their management, and the introduction of minimally invasive approaches that have enabled definitive and durable treatment for patients who were previously considered inoperable...

In 2014, the Canadian Cardiovascular Society (CCS) published a position statement on the management of thoracic aortic disease addressing size thresholds for surgery, imaging modalities, medical therapy, and genetics. It did not address issues related to surgical intervention. This joint Position Statement on behalf of the CCS, Canadian Society of Cardiac Surgeons, and the Canadian Society for Vascular Surgery provides recommendations about thoracic aortic disease interventions, including: aortic valve repair, perfusion strategies for arch repair, extended arch hybrid reconstruction for acute type A dissection, endovascular management of arch and descending aortic aneurysms, and type B dissection...

OBJECTIVE: To examine 30-day outcomes of robotic-assisted and pure laparoscopic ureteral reimplantation (LUR) vs open ureteral reimplantation (OUR) in adult patients for benign disease. METHODS: We identified adult patients undergoing LUR or OUR by urologists between 2006 and 2013 using the American College of Surgeons National Surgical Quality Improvement Program database, excluding those with concomitant partial cystectomy or ureterectomy. Multivariable regression modeling was used to assess for the independent association of minimally invasive surgery (MIS) with 30-day complications, reoperations, or readmissions...

OBJECTIVE: The decision to perform surgery in elderly is usually based on a complex consideration of benefit versus risk, which makes it difficult to perform controlled trials. The aim of this study was to assess the safety of cholecystectomy in patients aged 80 years and above. METHODS: The study was based on the Swedish National Register for Gallstone Surgery and ERC (GallRiks) 2006-2011. The cohort was cross-linked with the Swedish Patient Register in order to obtain data on previous medical history and postoperative events...

Medical 3-dimensional (3D) printing is emerging as a clinically relevant imaging tool in directing preoperative and intraoperative planning in many surgical specialties and will therefore likely lead to interdisciplinary collaboration between engineers, radiologists, and surgeons. Data from standard imaging modalities such as computed tomography, magnetic resonance imaging, echocardiography, and rotational angiography can be used to fabricate life-sized models of human anatomy and pathology, as well as patient-specific implants and surgical guides...

Coronary artery bypass grafting (CABG) is the gold standard in managing severe coronary artery disease. However, it is associated with prolonged recovery and potential complications, in part due to the invasiveness of the procedure. Less invasive CABG techniques attempt to improve the quality and quantity of life in the same way as surgical revascularization but with fewer complications. Minimally invasive coronary surgery (MICS) through a small thoracotomy allows for complete revascularization with good results in graft patency...

Throughout the modern era of cardiac surgery, most operations have been performed via median sternotomy with cardiopulmonary bypass. This paradigm is changing, however, as cardiovascular surgery is increasingly adopting minimally invasive techniques. Advances in patient evaluation, instrumentation, and operative technique have allowed surgeons to perform a wide variety of complex operations through smaller incisions and, in some cases, without cardiopulmonary bypass. With patients desiring less invasive operations and the literature supporting decreased blood loss, shorter hospital length of stay, improved postoperative pain, and better cosmesis, minimally invasive cardiac surgery should be widely practiced...

Cardiovascular surgery in Jehovah's Witness is challenging for surgeons on the ground that they refuse blood transfusion. We report 11 cases of cardiovascular surgery. All of the patients underwent elective surgery with cardiopulmonary bypass. Two cases underwent minimally invasive procedures. The mean preoperative hemoglobin level was 13.0 g/dl, and hematopoietic medicines were preoperatively administrated in 4 patients. Although 10 patients recovered satisfactory without blood transfusion, 1 surgical case was lost due to uncontrollable postoperative bleeding...

OBJECTIVES: Thymectomy may be part of the therapeutic strategy in patients with myasthenia gravis (MG) without thymoma. Median sternotomy is still considered as the gold standard, but during the last 15 years, several groups have demonstrated the non-inferiority of cervicotomy with upper sternotomy and minimally invasive techniques. To date, there is no consensus on surgical procedure choice. The aim of our study was to compare the morbidity and mortality of three techniques [cervicotomy with upper sternotomy versus sternotomy versus video-assisted thoracic surgery (VATS)/robotic-assisted thoracic surgery (RATS)] from the national database EPITHOR and to analyse French epidemiology...

INTRODUCTION: Harvesting of the greater saphenous vein is almost an inevitable part of coronary artery bypass grafting (CABG) operations, and it is done by two main techniques, i.e., conventional or open vein harvesting (OVH) and the minimally-invasive endoscopic vein harvesting (EVH). This study aimed to compare these two techniques in off-pump CABG procedures with respect to clinical and pathological outcomes. METHODS: This cohort study was conducted on CABG candidates during a one-year period from October 2013 through September 2014 in the Department of Cardiac Surgery at Mashhad University of Medical Sciences...

In recent years, minimally invasive vascular surgery is widely applied in treatment of cardiovascular diseases, and the manipulation of the guidewire is the essential skill for this surgery. Lots of time and money have to be taken to achieve the skill. In this paper, we present a multithreading guidewire simulator which can help the apprentice to gain the skill and modeling the guidewire is the core technique of the simulator. The guidewire is modeled by a fast and stable method based on the Cosserat theory of elastic rods...

Coronary artery disease is one of the leading causes of cardiovascular deaths worldwide. Approximately 70% of patients requiring coronary revascularisation receive endovascular stents. The endovascular procedure is the preferred option due to its minimally invasive nature when compared to open heart surgery. Stent delivery is paramount for the success of the endovascular procedure. Catheter delivery forces within tortuous blood vessels can produce vasoconstriction and injury, resulting in reactive intimal proliferation or distal embolisation associated with end-organ ischaemia and infarction...
