Herein is presented the case of an 83-year-old male patient in cardiogenic shock with acute aortic regurgitation that occurred six years after aortic valve replacement (AVR) with a 23 mm Trifecta™ valve. Prosthesis endocarditis was initially suspected because of a floating structure attached to the aortic valve that was visible on echocardiography. Emergency redo-AVR surgery was performed, but no signs of endocarditis were found intraoperatively. Hence, cusp tearing of the implanted bioprosthesis was considered to be the reason for the severe aortic regurgitation...

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...

We report a case of chronic dissecting thoracoabdominal aneurysm with intraoperative retrograde aortic dissection and rupture at proximal descending aorta, which was successfully treated by echoguided stent-graft insertion. An 82-year old male underwent thoracoabdominal aortic replacement for dilatation of infra-diaphragmatic aorta. Under F-F bypass, his thoracoabdominal aorta was replaced by a Dacron graft with 4-branches. After he weaned from F-F bypass, we found massive bleeding from proximal descending aorta...

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...

A comprehensive understanding of the native pulmonary blood supply is crucial in newborns with pulmonary atresia with ventricular septal defect and aortopulmonary collaterals (PA/VSD/MAPCA). We sought to describe the accuracy in terms of identifying native pulmonary arteries, radiation dose and anaesthetic time associated with multi-modality imaging in these patients, prior to their first therapeutic intervention. Furthermore, we wanted to evaluate the cumulative radiations dose and anaesthetic time over the study period...

The intraoperative in-vivo mechanical function of the left ventricle has been studied thoroughly using echocardiography in the past. However, due to technical and anatomical issues, the ultrasound technology cannot easily be focused on the right side of the heart during open-heart surgery, and the function of the right ventricle during the intervention remains largely unexplored. We used optical imaging and digital image correlation for the characterization of the right ventricle motion and deformation during open-heart surgery...

RATIONALE: Pulmonary vein stenosis (PVS) is a rare cardiovascular deformity that can lead to high mortality if left untreated. Patients frequently experience multiple complications such as hemoptysis, pulmonary hypertension, bronchial venous rupture and cardiac insufficiency. Currently, pulmonary vein stenosis balloon dilatation (stent implantation) is the only treatment, and this can be performed under local or general anesthesia. However, a case report on the general anesthesia management of PVS has not been previously reported...

We report a case of ascending aortic aneurysm repair and redo aortic valve replacement with a bioprosthesis 44 years after aortic valve replacement with a Starr-Edwards metal caged-ball prosthesis. The patient presented with a moderately stenotic caged-ball valve and a 50-mm ascending aortic aneurysm on a routine follow-up transthoracic echocardiography. We replaced the valve with a bioprosthesis at the time of aortic repair as the patient wished to stop anticoagulation therapy. Intraoperatively, we found that the cloth covering of the cage was nearly completely destroyed...

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...

We herein report a case involving a 56-year-old man who had experienced neck and lower back pain since the age of 23 years. Ankylosing spondylitis (AS) was diagnosed at 41 years of age, and treatment with sulfasalazine was initiated. At 44 years of age, the patient developed respiratory distress on exertion and chest pain. Aortic regurgitation (AR) was diagnosed via echocardiography, and the patient presented to our hospital for close examination and treatment. Coronary computed tomography angiography revealed no lesions in the coronary artery; however, magnetic resonance angiography revealed stenotic lesions in the left common carotid artery and left subclavian artery...

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...
