At our institution, implementation of a formal training course in Basic Focus Assessed Transthoracic Echocardiography (FATE) was associated with an improvement in anesthesia trainees' ability to obtain transthoracic echocardiography (TTE) images. Total image acquisition scores improved by a median (Q1, Q3) 9.1 (2.9,14.7) percentage points from pre-to post-hands-on FATE course (n=20; p=0.001). Participants who returned for a subsequent assessment 5 months following the course demonstrated a median (Q1, Q3) 18...

BACKGROUND: The perioperative assessment of right ventricular (RV) function remains a challenge. Tricuspid annular plane systolic excursion (TAPSE) using M-mode is a widely used measure of RV function. However, accurate alignment of the ultrasound beam with the direction of annular movement can be difficult with transesophageal echocardiography (TEE) to measure TAPSE, precluding effective use of M-mode to measure annular excursion. Tracking of specular reflectors in the myocardium may provide an angle-independent method to assess annular motion with TEE...

REVIEW
Ronak Shah, Elizabeth Zhou
Patients with atrial fibrillation and flutter routinely require transesophageal echocardiography with cardioversion. It is not uncommon to encounter patients with reduced ejection fractions, coronary artery disease, prior cardiac surgery, or obstructive sleep apnea. The anesthesiologist must carefully evaluate the patient and any available laboratory and study findings to assess for potential complications after anesthesia. Appropriate anesthetics must be chosen based on the preoperative evaluation. Additionally, because most of these cases are done without a secured airway, emergency medications and airway equipment must be readily available...

Myocardial contrast echocardiography (MCE) offers the opportunity to study myocardial perfusion defects in mice in detail. The value of MCE compared to SPECT, PET and CT consists of high spatial resolution, the possibility of quantification of blood volume and relatively low costs. Nevertheless, a number of technical and physiological aspects should be considered to ensure reproducibility among research groups. The aim of this overview is to describe technical aspects of MCE and the physiological parameters that influence myocardial perfusion data obtained with this technique...

Bupivacaine is a long-acting local anesthetic (LA) used for cutaneous infiltration, peripheral nerve blocks, epidural and spinal anesthesia. However, its application may result in cardiovascular complications such as: hypotension, bradycardia, cardiac arrest and toxic myocardial injury. The authors describe a 53-year-old male with a history of cigarette smoking, admitted for an elective inguinal hernia surgery. Before surgery, the patient received subarachnoid injection of bupivacaine (20 mg). After the operation, he developed transient hypotension...

Ultrasound (US) performed at the point of care has found fertile ground in perioperative medicine. In the hands of anesthesiologists, transesophageal echocardiography (TEE) has become established as a powerful diagnostic and monitoring tool in the perioperative care of cardiac and non-cardiac patients. A number of point-of-care US (POCUS) applications are relevant to perioperative care, including airway, cardiac, lung and gastric US. Although guidelines exist to define the scope of practice for basic and advanced TEE, there remains a lack of such guidelines for perioperative point-of-care ultrasound (POCUS), despite a number of recent calls for action in the academic anesthesia community...

INTRODUCTION: Ultrasound is a portable and safe technology that is increasingly used to assist anesthetic procedures and has been integrated into the routine practice of a wide range of invasive procedures. As a complementary diagnostic tool, publications related to perioperative support other than vascular access and nerve blocks are currently lacking. EVIDENCE ACQUISITION: Given the growing interest of anesthesiologists in acquisition of knowledge and skills of ultrasound, we propose a systematic review of the diagnosis, decision making or change in perioperative management of non-cardiac surgical patients derived from ultrasound practice...

A 2-year-old male intact Belgian Malinois was presented for exercise intolerance. A grade III/VI left basilar systolic murmur was detected. Echocardiography revealed moderate right atrial and ventricular dilation and increased pulmonic outflow velocity. Thoracic radiographs showed right heart enlargement and a dilated caudal vena cava. In addition, on the left lateral projection, an enlarged aberrant right cranial pulmonary lobar vein was suspected to be diverging ventrally from the course of the right cranial lobar bronchus and inserting more ventrally than normal in the region of the right atrium...

OBJECTIVES: The aim of this study was to compare the efficacy and safety of intracardiac echocardiography (ICE) from the left atrium (LA) with transesophageal echocardiography (TEE) for procedural guidance of transcatheter left atrial appendage occlusion (LAAO). BACKGROUND: TEE with general anesthesia is the current gold standard to guide LAAO. By the use of ICE from the LA, LAAO can be performed in local anesthesia and may potentially have advantages over TEE. METHODS: A single-center, cohort study of patients undergoing LAAO with the Amplatzer Cardiac Plug or Amulet (St...

Echocardiography is the cornerstone in the diagnosis of any valvular heart disease. The accurate diagnosis of aortic stenosis, the left ventricle function and the other heart valves evaluation are currently done by ultrasound alone. Prosthetic valve choice and dimensions prior to implantation can be done solely by proper use of echocardiography. The emergence of new methods to cure aortic stenosis such as trans-catheter aortic valve replacement (TAVR) emphasized the diagnostic value of cardiac ultrasound. The usefulness of echocardiography in TAVR can be divided in the baseline assessment (common to patients treated by conventional surgery), intra-procedural guidance of valve deployment and post-procedural follow-up...

The case is reported of a successful transcatheter implantation of an Edwards SAPIEN 3 valve (29 mm) into a failing tricuspid bioprosthesis (Sorin Pericarbon, 31 mm). The procedure was performed in a 69-year-old woman with post-rheumatic mitral and tricuspid valve disease. Multiple previous cardiac surgeries precluded the use of another surgical approach. A large, organized, two-piece thrombus in the enlarged right atrium was not considered an absolute contraindication to the procedure. The SAPIEN 3 valve was implanted under general anesthesia, via a femoral venous access, under three-dimensional transesophageal echocardiography guidance...
