The CNAP HD Monitor (CNSystems, Graz, Austria) and the ccNexfin (The ClearSight System: Edwards Lifesciences Corporation, Irvine, CA) are continuous, noninvasive blood pressure monitors using a finger-application device. These devices show a promising ability to allow for rapid detection of hemodynamic derangement when compared with oscillometry. The accuracy and precision of these devices as blood pressure monitors has been evaluated when compared with intra-arterial catheters. Additionally, they can be used to measure beat-to-beat cardiac output (CO)...

INTRODUCTION: This retrospective study examined the role of aortic valve (AV) disease in patients who underwent orthotopic liver transplantation (OLT) to determine the incidence of postoperative cardiac morbidity and mortality when compared with a matched control group without AV disease. METHODS: Patients were included in the AV group if diagnosed with aortic stenosis (AS) or aortic regurgitation or had received AV replacement prior to OLT. The AV group (n = 53) was matched to a control group (n = 212) with the following preoperative variables: type of organ transplanted, age, gender, race, body mass index, MELD, redo-transplantation, preoperative renal replacement therapy, nonalcoholic steatohepatitis, viral hepatitis, diabetes, and coronary artery disease...

An exaggerated vasoconstriction response to dexmedetomidine, an α-2 adrenergic agonist, has been associated with 2 genotypes: a deletion in the α-2B adrenoreceptor gene ( ADRA2B deletion) and SNP rs9922316 in the gene for protein kinase C type β ( PRKCB). We hypothesized that children with a marked systemic vascular resistance index (SVRI) increase following intravenous dexmedetomidine bolus would carry these genotypes. Following institutional review board approval, DNA samples from 16 children with transplanted hearts who participated in a study in the cardiac catheterization laboratory of hemodynamic responses to dexmedetomidine boluses underwent genotyping by polymerase chain reaction (PCR) amplification and PCR Sanger sequencing for the ADRA2B deletion and for PRKCB rs9922316...

Atrioventricular canal defects represent a diverse and challenging group of defects. Timing and surgical technique is greatly dependent on morphology of the valve as well as symptoms. Surgical options for repair of these defects are reviewed and presented below.

Advancements in postcardiac transplant care have resulted in significant reductions in morbidity and increased life expectancy for cardiac transplant recipients. Consequently, many cardiac transplant recipients are living long enough to require subsequent noncardiac surgery. The perioperative care of heart transplant recipients presents a unique challenge as many of the common preoperative risk assessments do not apply to a transplanted heart, immunosuppressive medications have side effects and potential for drug-drug interactions, and the denervated heart results in an altered autonomic physiology and response to medications...

Tracheoesophageal fistula develops in 5 % to 15 % of patients with esophageal cancer. Metal stent placement can be used for treatment. Stent placement can result in aspiration, hemorrhage, perforation, migration, and pneumonia. Patients may present for medical attention with unanticipated worsening of the fistula and stent displacement requiring special anesthetic care. We discuss the perianesthetic management of a patient with malignant tracheoesophageal fistula and stent migration who presented for endoscopic esophageal stent replacement...

Perioperative management of cardiovascular surgical procedures requiring cardiopulmonary bypass (CPB) in patients with hemophilia A poses a clinical challenge in coagulation management. Use of CPB requires the administration of an anticoagulant, usually unfractionated heparin, and also causes dilutional coagulopathy, platelet dysfunction or platelet consumption coagulopathy. Hypothermia and activation of the inflammatory cascade also affect coagulation. The effects of CPB on circulating levels of factor VIII have not been clearly defined...

S Michael Roberts, Trey Banbury, Anand Mehta
Anomalous left coronary artery from the pulmonary artery (ALCAPA), or Bland-White-Garland syndrome, is a rare congenital coronary anomaly that results in altered myocardial perfusion and a left to right shunt. It occurs in 1:300000 live births and represents 0.24% to 0.46% of all congenital cardiac diseases. Despite its rarity, it is one of the most common causes of ischemia and infarction in children. Ninety percent of these patients will die within the first year of life if untreated and diagnosing this abnormality in adulthood is extremely rare...

This article is first in the series to review the published literature on perioperative issues in patients undergoing thoracic solid organ transplantations. We present recent literature from 2016 on preoperative considerations, organ preservation, intraoperative anesthesia management, surgical techniques, postoperative complications, and the impact of perioperative management on short- and long-term outcomes that are pertinent to thoracic transplantation anesthesiologists.

Cardiac surgical care of patients continued to evolve rapidly in 2016. In this article, 3 topics of considerable change are discussed based on recent publications. The first topic reviews the potential risks and benefits of newly instituted low-risk percutaneous aortic valve replacement. The second topic reviews the increasing utilization of more extensive arch replacements in acute type A dissection. The final topic reviews current trends and justification for changes in patterns of use of cardioplegia options...

In 2016, demand for the presence of cardiothoracic anesthesiologists outside of the cardiac operating rooms continues to expand. This article is the second in this annual series to review relevant contributions in postoperative cardiac critical care that may impact the cardiac anesthesiologist. We explore the use of extracorporeal membrane oxygenation (ECMO), management of postoperative atrial fibrillation, coagulopathy, respiratory failure, and role of quality in cardiac surgery.

Clinical research and outcome studies dominated the publication spectrum for the cardiothoracic anesthesiologist in 2016. Echocardiography is an important tool in the armamentarium of the cardiothoracic anesthesiologist. Technology is advancing at a fast pace: A new method to quantify the regurgitant volume in mitral regurgitation has been described in an experimental model and been validated in humans. Interesting studies on key elements of our daily practice have been published: Does tranexamic acid decrease the transfusion requirements after cardiac surgery? Are patients with a postoperative cognitive deficit at risk for dementia 7...

Echocardiography plays a major role in the diagnosis and management of hemodynamic compromise during the perioperative period. Both transthoracic and transesophageal echocardiography have been shown to improve outcomes after cardiac and noncardiac surgery. Teaching basic echocardiographic skills to perioperative physicians remains a challenging task. Thus far, simulation-based medical education has been proven useful in teaching specific procedural skills and management of infrequent catastrophic events. Simulation-based echocardiography education has the potential to facilitate clinical training in echocardiography...

Anesthesia for lung transplantation remains one of the highest risk surgeries in the domain of the cardiothoracic anesthesiologist. End-stage lung disease, pulmonary hypertension, and right heart dysfunction as well as other comorbid disease factors predispose the patient to cardiovascular, respiratory and metabolic dysfunction during general anesthesia. Perhaps the highest risk phase of surgery in the patient with severe pulmonary hypertension is during the induction of anesthesia when the removal of intrinsic sympathetic tone and onset of positive pressure ventilation can decompensate a severely compromised cardiovascular system...

Anesthesia providers are frequently exposed to radiation during routine patient care in the operating room and remote anesthetizing locations. Eighty-two percent of anesthesiology residents (n = 57 responders) at our institution had a "high" or "very high" concern about the level of ionizing radiation exposure, and 94% indicated interest in educational materials about radiation safety. This article highlights key learning points related to basic physical principles, effects of ionizing radiation, radiation exposure measurement, occupational dose limits, considerations during pregnancy, sources of exposure, factors affecting occupational exposure such as positioning and shielding, and monitoring...
