BACKGROUND: Segmental analysis of diseased mitral valves is important to predict a successful surgical valve repair. An assessment was made of the comparative accuracy of intraoperative three-dimensional (3D) and two-dimensional (2D) transesophageal echocardiography (TEE) in the evaluation of mitral valve lesions when compared with intraoperative surgical segmental analysis. METHODS: A total of 42 consecutive patients (12 females, 30 males; mean age 70.5 ± 14 years) with severe mitral valve regurgitation due to degenerative disease and who underwent mitral valve repair was enrolled in the study...

OBJECTIVE: Intraoperative Doppler-determined renal resistive index (RRI) is a promising early acute kidney injury (AKI) biomarker. As RRI continues to be studied, its clinical usefulness and robustness in research settings will be linked to the ease, efficiency, and precision with which it can be interpreted. Therefore, the authors assessed the usefulness of computer vision technology as an approach to developing an automated RRI-estimating algorithm with equivalent reliability and reproducibility to human experts...

OBJECTIVES: The routine application angle correction (AnC) in hemodynamic measurements with transesophageal echocardiography currently is not recommended but potentially could be beneficial. The authors hypothesized that AnC can be applied reliably and may change grading of aortic stenosis (AS). DESIGN: Retrospective analysis. SETTING: Single institution, university hospital. PARTICIPANTS: During phase I, use of AnC was assessed in 60 consecutive patients with intraoperative transesophageal echocardiography...

BACKGROUND Ex situ liver surgery allows liver resection and vascular reconstruction in patients who have liver tumors located in critical sites. Only a small series of studies about ex situ liver surgery is available in the literature. No anesthesia management experience has been previously published. The aim of the currents study was to summarize our experience with anesthetic management of patients during ex vivo liver surgery. MATERIAL AND METHODS The first 43 patients who received ex vivo liver surgery between January 2007 and April 2012 were included...

Intravenous leiomyomatosis (IVL) is a condition in which leiomyoma originating from uterine myoma or intrauterine venous walls develops intravenously. A single-stage operation was planned by the departments of gynecology and cardiovascular surgery for a patient in which the IVL was extended across the tricuspid valve. It was possible to safely perform perioperative care with continued evaluation of the tumor position and intravascular volume through the use of transesophageal echocardiography (TEE). TEE can be useful in the intraoperative care of patients with intracardiac tumor extension as in this case...

Alpha-1 antitrypsin deficiency (AATD) is an inherited disorder affecting the lung, liver, and rarely skin. The most frequent features of AATD consist of chronic lung disorders related to protease-antiprotease imbalance in the respiratory system, to which lung transplantation is frequently indicated. We describe a case of aortic dissection in a 55-year-old male who underwent left single lung transplantation for respiratory failure due to AATD-related emphysema. Extracorporeal membrane oxygenation (ECMO) was indicated during the procedure, and an arterial cannula was placed into the descending aorta and a venous cannula was placed into the right femoral vein...

Perioperative pulmonary embolism can go undetected until the sudden onset of cardiopulmonary collapse. Point of care echocardiography in such setting can narrow the differential diagnosis of precipitous instability and facilitate tailored, rather than empiric, therapy in the event of a massive pulmonary embolism. We describe the diagnosis and successful multidisciplinary management of intraoperative massive pulmonary embolism aided by both transthoracic and transesophageal echocardiography. Key aspects regarding the classification and treatment of pulmonary embolism are subsequently reviewed...

BACKGROUND: Previous studies have demonstrated that three-dimensional (3D) transesophageal echocardiography (TEE) is an alternative to multi-detector computed tomography (MDCT) for aortic valve sizing in transcatheter aortic valve replacement (TAVR). However, conventional cross-sectional analysis of aortic annulus by 3D TEE has some limitations such as lengthy analytical time. A novel software for automated valve measurement has been developed for 3D TEE. We evaluated the accuracy and analytical time of aortic annular measurements using this novel automated software in the clinical setting...

Tricuspid regurgitation (TR) is a common valvular lesion which may affect morbidity and mortality. It can be related to an intrinsic abnormality of the tricuspid valve leaflets (organic) or secondary to annular dilatation (functional). Often organic and functional TR coexist in the same patient. A long standing TR is associated with ascites, congestive hepatopathy, peripheral edema, renal failure, and abdominal fullness which significantly affect the outcome. In particular, the perioperative course may be complicated due to both the presence of comorbidities and the development of a severe postoperative right ventricle (RV) dysfunction...

Mitral stenosis (MS) is prevalent in 0.02-0.2% of the population in developed countries. The pathophysiology of MS results in elevated left atrial pressures and over-time results in pulmonary hypertension (HTN) which ultimately affects the right ventricle. In addition, MS restricts the diastolic filling of the left ventricle. Therefore, during induction patients with MS are limited by their ability to increase cardiac output by increasing stroke volume. Anesthesia goals in severe MS are to avoid sudden changes in heart rate, as well as systemic and pulmonary artery pressures...

BACKGROUND: Patients undergoing cardiac surgery need extensive and invasive monitoring, which needs to be individually adapted for each patient and requires a diligent risk-benefit analysis. The use of a pulmonary artery catheter (PAC) seems to be justifiable in certain cases; therefore, the preoperative diagnosis of pulmonary hypertension represents an indication for perioperative monitoring with PAC in the S3 guidelines of the German Society for Anesthesiology and Intensive Care Medicine (DGAI)...

Background: This study aimed to investigate the specific causes for switching patients from minimally invasive transthoracic occlusion to surgical repair under cardiopulmonary bypass (CPB). By retrospectively analyzing 340 cases, we sought to provide the clinical reference for improving the success rate of minimally invasive transthoracic device closure of ventricular septal defect (VSD). Methods: Among the 340 patients who underwent transthoracic closure of VSDs in the past 3 years at our hospital, 26 patients needed to be switched to surgical repair under CPB due to failure of transthoracic closure...

BACKGROUND: Remote ischemic preconditioning (RIPC) has been suggested to protect against certain forms of organ injury after cardiac surgery. Previously, we reported the main results of RIPHeart (Remote Ischemic Preconditioning for Heart Surgery) Study, a multicenter trial randomizing 1403 cardiac surgery patients receiving either RIPC or sham-RIPC. METHODS AND RESULTS: In this follow-up paper, we present 1-year follow-up of the composite primary end point and its individual components (all-cause mortality, myocardial infarction, stroke and acute renal failure), in a sub-group of patients, intraoperative myocardial dysfunction assessed by transesophageal echocardiography and the incidence of postoperative neurocognitive dysfunction 5 to 7 days and 3 months after surgery...

Orthotopic liver transplantation (OLT) is characterized by significant hemodynamic disturbances and anesthetic challenges. Intraoperative transesophageal echocardiography (TEE) can be used to guide management during these procedures. This review examines the role of echocardiography during OLT, presents common TEE findings during each phase of OLT, and discusses the benefits demonstrated with TEE use and the safety of TEE in this patient population. Finally, the authors propose an algorithm for the safe use of TEE during OLT...

We describe a case of intraoperative cardiac trombosis during orthotopic liver transplant surgery that resulted in intraoperative death. By using transesophageal echocardiography, the cause of the descompensation of the patient could be determined and the mechanism of trombus migration from thrombi from the venous circulation to the left heart was accurately observed.

We present optimally reconstructed three-dimensional computed tomography images of left ventricular outflow obstruction, comprehensive left ventriculography, and comparable intraoperative transesophageal echocardiography, as well as serial operative pictures, to facilitate the understanding of live-heart anatomy of hypertrophic obstructive cardiomyopathy. As shown in this case, detailed morphological analysis around the left ventricular outflow tract using preoperative computed tomography would be feasible and useful...
