The natural history of mitral regurgitation (MR) results in significant morbidity and mortality. Innovations in non-invasive imaging have provided new insights into the pathophysiology and quantification of MR, in addition to early detection of left ventricular (LV) dysfunction and prognostic assessment in asymptomatic patients. Transthoracic (TTE) and transesophageal (TOE) echocardiography are the mainstay for diagnosis, assessment and serial surveillance. However, the advance from 2D to 3D imaging leads to improved assessment and characterization of mitral valve (MV) disease...

Paradoxical low-flow, low-gradient aortic stenosis (LFLG AS) is recognized as a subtype of aortic stenosis. A small left ventricular (LV) cavity with marked LV concentric remodeling leads to a reduced stroke volume in this condition. The case is reported of a paradoxical LFLG AS patient who was undergoing treatment for pulmonary hypertension (PH) and interstitial pneumonia associated with scleroderma. Echocardiography demonstrated enlargement of the right ventricle and a diminished LV cavity. Moreover, the aortic valve opening was restricted despite a preserved LV ejection fraction (61%)...

The case is described of a successful MitraClip procedure performed on an 88-year-old patient with severe mitral regurgitation (MR), five years after she had undergone mitral valve repair using the Alfieri surgical procedure. It is suggested that the MitraClip procedure is an option in patients with severe MR persisting after the Alfieri procedure. Video 1: Transesophageal echocardiography before the MitraClip procedure. Severe mitral regurgitation with preserved left ventricular systolic function. The main regurgitant jet originates from the medial commissure...

A 79-year-old woman with a history of ischemic dilated cardiomyopathy, severely depressed left ventricular ejection fraction and significant mitral regurgitation (MR) was admitted to the authors´ institution for percutaneous mitral valve repair. Transesophageal echocardiography (TEE) revealed the presence of a posterior mitral cleft at the P2 level, causing a trileaflet mitral valve that contributed significantly to the regurgitant jet. The procedure was performed under general anesthesia and guided by real-time three-dimensional TEE...

Mitral annuloplasty ring thrombosis is an extremely infrequent pathology, for which no evidence-based antithrombotic management has yet been described. Herein is presented a case of heterozygous Factor V Leiden (FVL) and hyperhomocysteinemia with homozygous methylenetetrahydrofolate reductase (MTHFR) mutations that caused early thrombosis of the mitral annuloplasty ring. The clinical management and antithrombotic treatment of the patient, and the implications of hyperhomocysteinemia, are discussed. Video 1: Mobile 9-mm thrombus of mitral annuloplasty ring on two-dimensional (2D) transesophageal echocardiography...

Pulmonary valve infections without the involvement of other valves account for only 1.5- 2% of all infective endocarditis cases. Isolated pulmonary valve endocarditis due to fungus is extremely rare. The case is presented of a 36-year-old male who was found to have isolated pulmonary valve endocarditis caused by a very rare organism, Candida parapsilosis, and that was solely managed with medical therapy. The patient was evaluated for three weeks of lowgrade fever, generalized rash and fatigue, and found to have C...

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...

BACKGROUND: Oral anticoagulation (OAC) is prescribed for left atrial thrombi (LAT) in non-rheumatic atrial fibrillation (AF) and/or atrial flutter (AFL). The study objective was to review the existing evidence regarding LAT resolution in non-rheumatic AF and/or AFL with OAC agents. METHODS: Data sources included PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL) between January 1, 1991 and February 1, 2017. English-language studies that assessed LAT resolution with OAC agents in subjects with non-rheumatic AF and/or AFL, by serial transesophageal echocardiography (TEE), and with follow-up times ≥3 weeks and < 1 year were selected...

AIMS: Percutaneous left atrial appendage (LAA) occlusion is occasionally incomplete, with residual permeability of the LAA on cardiac computed tomography. The cause for this is unclear. Our objective was to determine if residual permeability was related to incomplete endothelialization. METHODS: A total of 35 consecutive patients contraindicated for anticoagulant therapy admitted for LAA occlusion were included; 12 patients received a Watchman device (Boston Scientific) and 23 patients received an Amplatzer Cardiac Plug (St...

The abundance of, and reliance upon, human electro-muscular incapacitation (HEMI) devices, especially in law enforcement, has generated scrutiny and examination of these technologies. The purpose of this study was to examine cardiovascular effects resulting from typical (5 sec) and longer activation (20 sec) HEMI applications studying myocardial function and peripheral vascular system using a combination of invasive cardiovascular catheters and transesophageal echocardiography (TEE). Six healthy swine (Sus scrofa) 3-5 months in age and weighing between 60 and 86 kg were anesthetized and exposed to the TASER Model X26 waveform while transesophageal echocardiography was performed...

BACKGROUND AND AIM: The clinical utility of transesophageal echocardiography (TEE) after brain ischemia (BI) remains a matter of debate. We aimed to evaluate the clinical impact of TEE and to build a score that could help physicians to identify which patients should better benefit from TEE. METHODS: This prospective, multicenter, observational study included patients over 18 years old, hospitalized for BI. TEE findings were judged discriminant if the results showed important information leading to major changes in the management of patients...

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...

Cardiac myxomas are frequently located in the left or right atria, with multiple locations being rare. We report a 59-year-old healthy female with 5 months of cough and exertional dyspnea. A transthoracic echocardiography (TTE) exhibits a 9 × 5 cm nonpedunculated tumor arising from the interatrial septum (IAS) and inhabiting both atria, but was unable to depict the relation with the IAS. Transesophageal echocardiography exposes a single tumor crossing the IAS through an ostium secundum atrial septal defect (ASD) causing right heart functional impairment...

BACKGROUND: Mitral regurgitation in ischemic heart disease (IMR) is a strong predictor of outcome but until now, pathophysiology is not sufficiently understood and treatment is not satisfying. We aimed to systematically evaluate structural and functional mitral valve leaflet and annular characteristics in patients with IMR to determine the differences in geometric and dynamic changes of the MV between significant and mild IMR. METHODS: Thirty-seven patients with IMR (18 mild (m)MR, 19 significant (moderate+severe) (s)MR) and 33 controls underwent TEE...

Various metrics have been used in curriculum-based TEE training programs to evaluate acquisition of proficiency. However, the quality of task completion, i.e. the final image quality, was subjectively evaluated in these studies. Ideally, the end point metric should be an objective comparison of the trainee-acquired image with a reference ideal image. Therefore, we developed a simulator-based methodology of pre-clinical verification of proficiency (VOP) in trainees by tracking objective evaluation of the final acquired images...

The optimal periprocedural imaging strategy during transcathether aortic valve replacement (TAVR) performed under moderate sedation is debated. Transthoracic echocardiography (TTE) provides suboptimal views due to poorer resolution and patient positioning, whereas use of transesophageal echocardiography (TEE) under moderate sedation is not widely utilized. The aim of our study was to compare the value of TTE in comparison with TEE guidance under moderate sedation during TAVR. The study population included 144 consecutive patients (mean age 83±11 years, 78(54%) females) who had TAVR under moderate sedation using either a TTE (n=96) or TEE (n=48)...
