Aortic stenosis (AS) is the most common type of valvular heart disease in the elderly. Surgical aortic valve replacement (SAVR) has been the standard practice for treating severe, symptomatic AS, but recently new treatment options have emerged. Transcatheter aortic valve replacement (TAVR) is now an established treatment option in patients at high surgical risk. In this review, we focus on recent developments and compare the two treatment methods in specific populations in terms of efficacy and safety (e.g...

OBJECTIVES: This study sought to determine whether plasma catecholamines and monoamine oxidase-B (MOA-B) are associated with post-operative atrial fibrillation (POAF) in patients undergoing elective cardiac surgery. BACKGROUND: Although intra- and post-operative adrenergic tone has been demonstrated to be an causative factor for POAF, the role and association of pre-operative plasma catecholamines remains unclear. METHODS: Prior to administration of anesthesia on the morning of surgery, blood samples were obtained from 324 patients undergoing nonemergent coronary artery bypass graft and/or aortic valve surgery with cardiopulmonary bypass at East Carolina Heart Institute...

REVIEW

β-Blockers are useful drugs in several clinical cardiologic scenarios. Their use in the perioperative period and in critically ill patients is increasing, but their effect on clinically relevant outcomes remains controversial. Long-acting β-blockers can have detrimental effects that are difficult to be counteracted in these settings. The authors describe the possible clinical uses of ultra-short-acting β-blockers (esmolol and landiolol) in the perioperative period and in critically ill patients because these drugs have the beneficial effects of β-blockers, but do not have the detrimental effects of long-acting agents...

OBJECTIVE: Currently, there are no large-scale studies that compare differences in case duration of aortic valve replacements (AVRs). The primary objective of this study was to determine associations of hospital facility type, geographic location, case volume per year, and time of day with duration of valve replacement surgery. DESIGN: Retrospective. SETTING: Data from the National Anesthesia Clinical Outcomes Registry. PARTICIPANTS: National data from university and non-university hospitals...

OBJECTIVE: The adoption of endovascular aneurysm repair (EVAR) during the past two decades has led to significantly shorter length of stay as well as lower hospital resource use. Currently, most patients are admitted to the hospital after EVAR; however, there are no standard observation periods, and timing of discharge is based on clinical judgment. The aim of this study was to confirm the safety and feasibility of performing EVAR as outpatient surgery. METHODS: We developed criteria to identify patients for potential same-day discharge (infrarenal aneurysm, low perioperative risk, to be accompanied for first 24 hours)...

This study evaluated the effects of inhaled nitric oxide (iNO) therapy combined with intravenous (IV) corticosteroids on hemodynamics, selected cytokines, and kidney messenger RNA toll-like receptor 4 (mRNA TLR4) expression in ischemia-reperfusion injury animal model. The primary endpoint was the evaluation of circulatory, respiratory, and renal function over time. We also investigated the profile of selected cytokines and high-mobility group box 1 (HMGB1) protein, as well as renal mRNA TLR4 activation determined by quantitative real-time polymerase chain reaction analysis...

BACKGROUND: Repair of congenital heart defects involving the right ventricular outflow tract may require the implantation of a right ventricle to pulmonary artery conduit. This conduit is likely to be replaced during childhood. This study compares the operative outcomes of the replacement procedure of Contegra® and homografts in pulmonary position. METHODS: From 1999 to 2016, 82 children underwent 87 right ventricle to pulmonary artery conduit replacements (60 Contegra® and 27 homografts)...

PURPOSE: Fibrin sealants are used for hemostasis during surgery. Commercially available fibrin sealants are made of materials of human or animal origin. We developed a novel recombinant fibrin sealant patch (KTF-374) that has thin and flexible properties. This study evaluated the hemostatic efficacy of KTF-374 for various patterns of bleeding in rabbits, as compared with that of the existing fibrin-coated collagen fleece (FCCF). MATERIALS AND METHODS: Test hemostats used were KTF-374 and FCCF...

OBJECTIVE: To explore the role of echocardiography in pre-procedural,peri-procedural and post-procedural stages of transapical transcatheter aortic valve implantation (TAVI) in patients with aortic regurgitation (AR). METHODS: 31 patients with pure/dominant AR at a high risk on surgery were enrolled in this study. The degree of their aortic regurgitation was evaluated before TAVI,as well as the related diameters of aortic root and the left ventricular systolic function measured by transthoracic echocardiography (TTE)...

Regional anesthesia has been used to help create local sympathectomy and improve blood flow in plastic surgery procedures involving tissue grafts and flaps. However, anesthetic techniques that reduce systemic vascular resistance must be used with caution in patients with aortic stenosis (AS). Combined neuraxial and general anesthesia with careful titration of the local anesthetic dose can be a safe approach for patients with AS undergoing microvascular procedures. We present the anesthetic management of the first North American penile transplant, on an obese patient with moderate AS...

Background/aim: Myocardial protection is an important factor of open heart surgery and biological biomarkers (lactate, CKMB, cardiac troponin I, and pyruvate) are used to assess myocardial damage. This study compares the effects of dexmedetomidine and remifentanil on myocardial protection during coronary artery bypass grafting (CABG) surgery. Materials and methods: Patients scheduled for elective CABG surgery (n = 60) were included in this study. Anesthesia induction was introduced with propofol, fentanyl, and vecuronium bromide...

PURPOSE: Unilateral re-expansion pulmonary edema (RPE) is a rare but one of the most critical complications that may occur after re-expansion of a collapsed lung after minimally invasive cardiac surgery (MICS) with mini-thoracotomy. METHODS: We performed a total of 40 consecutive patients with MICS by right mini-thoracotomy with single-lung ventilation between January 2013 and June 2016. We divided the patients into control group (n = 13) and neutrophil elastase inhibitor group (n = 27)...

The cardiac catheterization laboratory is advancing medicine by performing procedures on patients who would usually require sternotomy and cardiopulmonary bypass. These procedures are done percutaneously, allowing them to be performed on patients considered inoperable. Patients have compromised cardiovascular function or advanced age. An anesthesiologist is essential for these procedures in case of hemodynamic compromise. Interventionalists are becoming more familiar with transcatheter aortic valve replacement and the device has become smaller, both contributing to less complications...

INTRODUCTION: Aortic dissection is a life threatening disease and is usually accompanied by a high rate of mortality and morbidity. Here we present a case report in which intraoperative tranesophageal echocardiography was used for intraoperative assessments of thoracic aortic dissection due to cocaine abuse. CASE PRESENTATION: A 45- year- old male was admitted to a university hospital due to severe chest pain. He was suffering from severe excruciating chest pain that had started after a psychological stress, leading to heavy cocaine abuse...

BACKGROUND: Among patients undergoing noncardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently, there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI and the association of perioperative MI with perioperative transfusion...
