ReviewPeripartum Cardiomyopathy: Current Options for Treatment and Cardiovascular Support.
Peripartum cardiomyopathy is a rare form of acute heart failure but the major cause of all deaths in pregnant patients with heart failure. Improved survival rates in recent years, however, emphasize the importance of early recognition and initiation of heart failure treatment. This article, therefore, attempts to raise awareness among cardiac and obstetric anesthesiologists as well as intensivists of this often fatal diagnosis. ⋯ Earlier recognition of this rare condition and a new generation of mechanical circulatory devices has contributed to the improved outcome. More frequently, patients in cardiogenic shock who fail medical management are successfully bridged to recovery on extracorporeal circulatory devices or survive with a long-lasting implantable ventricular assist device. The outcome of transplanted patients with peripartum cardiomyopathy, however, is worse compared to other recipients of heart transplants and warrants further investigation in the future.

ReviewThe Use of Subcostal Echocardiographic Views to Guide the Insertion of a Right Ventricular Temporary Transvenous Pacemaker-Description of the Technique.
The need for temporary cardiac pacing may occur in emergency and elective situations and may require transvenous right ventricular lead placement. The treatment of bradyarrhythmias presents the most common perioperative emergency indication. Intraoperatively, temporary rapid right ventricular pacing is accepted as a safe, titratable, and highly reliable method to achieve deliberate hypotension, and it has become a routine practice in the anesthetic management of cardiovascular interventions. ⋯ When used to guide transvenous pacemaker wire insertion, subcostal echocardiographic imaging offers attractive advantages over blind or fluoroscopic placement, including rapid deployment, avoidance of radiation, real-time visualization of the lead in relation to the cardiac structures, and early detection of potential complications, such as tamponade. Although several articles on echocardiographic guidance for transvenous pacing have been published in other acute care specialty fields in the last decade, this is the first description of the technique and of the recommended echocardiographic views in a perioperative context. In addition, a review of the current literature is presented, and the specific advantages and disadvantages of the approach are discussed in this article.

Randomized Controlled TrialA Novel Speckle-Tracking Based Method for Quantifying Tricuspid Annular Velocities in TEE.
A novel speckle-tracking-based option for measuring tricuspid annular velocities in the midesophageal 4-chamber view (ME4C) was compared with velocities measured by tissue Doppler in the apical-4 chamber view (AP4C). Because this method was based on a modified speckle-tracking-based measurement of tricuspid annular plane systolic excursion (TAPSE), the authors also compared TAPSE by speckle tracking in the ME4C with TAPSE by M-mode in the AP4C. The authors hypothesized that velocities measured by speckle tracking in transesophageal echocardiography (TEE) would be similar, correlate, and agree with those measured by tissue Doppler in transthoracic echocardiography (TTE). ⋯ Tricuspid annular velocities (S'STE, E'STE) determined by speckle tracking in TEE seem to be promising surrogates for velocities measured in TTE. This may be important for perioperative assessment of the right ventricle.

ReviewThe Year in Vascular Anesthesia: Selected Highlights From 2018.
This special article is the second in an annual series for the Journal of Cardiothoracic and Vascular Anesthesia that is specifically dedicated to highlights in vascular anesthesiology published in 2018. This review begins with 2 updates in preoperative medicine in the vascular surgery population, including recent publications regarding the management of angiotensin-converting enzyme inhibitors and angiotensin II receptor blockers and antiplatelet medications in the perioperative period. ⋯ The final section focuses on quality in vascular surgery and evaluates recent publications that examine the safety and feasibility of fast-track endovascular aortic surgery. Even though this is only a sampling of the literature published in 2018 relevant to the cardiovascular anesthesiologist, these themes represent some of the topics most clinically relevant to the perioperative period.
