  ABSTRACT: The aortic valve treatment revolution continues with the maturation of aortic valve repair and the dissemination of transcatheter aortic valve implantation. The recent publication of comprehensive multidisciplinary guidelines for diseases of the thoracic aorta has assigned important roles for the cardiovascular anesthesiologist and perioperative echocardiographer. Although intense angiotensin blockade improves outcomes in heart failure, it might further complicate the maintenance of perioperative systemic vascular tone. Ultrafiltration as well as intensive medical management guided by the biomarker brain natriuretic peptide improves outcomes in heart failure. Continuous-flow left ventricular assist devices have further improved outcomes in the surgical management of heart failure. Major risk factors for bleeding in the setting of these devices include advanced liver disease and acquired von Willebrand syndrome. The metabolic modulator perhexiline improves myocardial diastolic energetics to achieve significant symptomatic improvement in hypertrophic cardiomyopathy. A landmark report was also published recently that outlines the major areas for future research and clinical innovation in this disease. Landmark trials have documented the outcome importance of perioperative cerebral oxygen saturation monitoring as well as the outcome advantages of the Sano shunt over the modified Blalock-Taussig shunt in the Norwood procedure. Furthermore, the development and evaluation of pediatric-specific ventricular assist devices likely will revolutionize the mechanical management of pediatric heart failure. A multidisciplinary review has highlighted the priorities for future perioperative trials in congenital heart disease. These pervasive developments likely will influence the future training models in pediatric cardiac anesthesia.

  ABSTRACT: The hybrid operating room is the venue for transcatheter therapy with the convergence of 3 specialties: cardiac surgery, cardiovascular anesthesiology, and interventional cardiology. Transcatheter aortic valve replacement is proof that cardiac specialists have embraced the endovascular revolution. Because pharmacologic conditioning and ischemic myocardial conditioning are safe and effective, they are currently the focus of multiple trials. Angiotensin blockade, anemia, and endoscopic saphenous vein harvesting worsen outcome after coronary artery bypass graft (CABG) surgery. Although off-pump CABG surgery is equivalent to on-pump CABG surgery, it may improve outcomes in high-risk groups. Although percutaneous coronary intervention (PCI) significantly decreases mortality after myocardial infarction, the evidence is less convincing for intra-aortic balloon counterpulsation. Even though prasugrel recently was approved for platelet blockade in PCI, it may be superseded by ticagrelor. Although PCI and CABG surgery appear equivalent for multivessel coronary disease, CABG surgery lowers revascularization rates and also has superior outcomes in diabetics and the elderly. Hetastarch and N-acetylcysteine both increase bleeding and transfusion in cardiac surgery. Factor VII can treat life-threatening bleeding, but its safety requires further evaluation. Because eltrombopag and romiplostim stimulate platelet production, they may have a future role in hemostasis after cardiac surgery. Even though fenoldopam, atrial natriuretic peptide, and sodium bicarbonate are nephroprotective, further trials must confirm these findings. Intensive insulin therapy offers no further outcome advantage and significantly increases hypoglycemic risk. The past year has witnessed the advent of a new clinical venue, new devices, and new drugs. The coming year will most likely advance these achievements.
