OBJECTIVE: To elucidate the preoperative, intraoperative, and postoperative utility of echocardiographic technology in occlusion of ventricular septal defect (VSD) via small chest incision. METHODS: We performed occlusion of VSD via small chest incision in 446 children. Before surgery, a multiple-section transthoracic echo-cardiogram (TTE) was employed to evaluate various parameters (including the size, position, and type) of the VSD region as well as the condition of neighboring tissues...

Cardiac tumors are rare, and 3-quarters of these tumors are benign and nearly half of the benign tumors are myxomas. Metastases to the heart are more common than primary cardiac tumors. Cardiac tumors present obstructive, constitutional and embolic signs and symptoms. Echocardiograms, chest computed tomography (CT) and magnetic resonance imaging (MRI) scan are very useful for diagnosis. Surgery is indicated in patients with benign tumor, and chemo/radio-therapy in patients with malignant tumors. Prognosis after surgery is good, instead poor prognosis for patients with malignancy...

AIM: Contrast-enhanced transesophageal echo-cardiography (c-TEE) represents the gold standard in the diagnosis of patent foramen ovale (PFO) but it is not always well tolerated by the patient, and it is influenced by his cooperation. Purpose of the present study was to assess feasibility and safety of c-TEE through the oral way using a miniaturized 10-Fr, monoplane probe (Acunav-TEE) and establish its utility in the diagnosis or PFO when compared with c-TEE using the traditional multiplane probe (standard-TEE)...

INTRODUCTION: Echocardiographic parameters for predicting cardioversion (CV) outcome and long-term sinus rhythm (SR) maintenance in patients with nonvalvular atrial fibrillation (AF) are not accurately defined. AIMS: The authors aim was to evaluate the role of left atrial appendage (LAA) flow velocity detected by transesophageal echocardiography before CV for prediction of short and long-term (1 year) outcome of CV in patients with nonvalvular AF. METHODS: One hundred and nine patients (66 males, mean age: 57 +/- 13 years) with nonvalvular AF lasting more than 48 hours but less than 1-year duration underwent transthoracic and transesophageal echocardiography before either electrical or pharmacological CV attempt...

BACKGROUND: Transesophageal echocardiography (TEE) is used routinely before percutaneous transvenous mitral commissurotomy (PTMC) to detect left atrial appendage thrombus (LAAT) to avoid the risk of embolic complications. The issue of whether patients with small and fixed LAAT should be denied the potential benefit of PTMC is worth examining. OBJECTIVE: To evaluate the safety and efficacy of PTMC with Inoue balloon catheter in mitral stenosis patients with LAAT using TEE continuous monitoring during the procedure...

The incidence of left atrial (LA) spontaneous echo contrast (SEC) and the clinical and echocardiographic variables related to it were prospectively evaluated in a series of 60 patients with mitral stenosis (MS) undergoing transoesophageal echocardiography (TEE) with a 5 MHz multiplane transducer. LA-SEC was found in 39 patients (65%) employing TEE. Statistical analysis showed a significant relationship between the presence of SEC and MS without mitral regurgitation (MR) (P < 0.05), MS with < or = MR grade II (P < 0...

We describe a 51-year-old woman with an acquired coronary fistula to the left ventricle. Reports in the literature about acquired coronary fistulas to the left ventricle are scarce. In this patient, the fistula developed after septal myectomy for hypertrophic obstructive cardiomyopathy. Transesophageal echo-cardiography may be the preferred method to diagnose and evaluate these fistulas. Moreover, in contrast to fistulas to the right ventricle, conservative management carried a good prognosis in this patient...

An alternative clinical management strategy and cost analysis model is presented for patients with atrial fibrillation of >2 days' duration who may benefit from immediate cardioversion with self-administered low-molecular-weight heparin (enoxaparin) as a bridge antithrombotic therapy to warfarin, after a negative transesophageal echo-cardiography (TEE) screening for thrombus. Assuming no difference in stroke or bleeding rates, our cost minimization model shows that the TEE-guided enoxaparin treatment costs are $1353 lower per patient than an intravenous unfractionated heparin approach...

Most traumatic aortic injuries are the result of penetrating causes, whereas blunt aortic injury is less common. The initial treatment is determined by the patient's condition. Diagnostic studies include catheter arteriography, computed tomography, and transesophageal echo cardiography. This article summarizes the initial evaluation and management of patients with an aortic injury and describes the various treatment options such as delayed selective management, endovascular solutions, and surgical repair.

A 59-year-old man was transferred to our hospital because of severe right leg pain, dyspnea and anuria. Due to severe cyanosis of the legs below the knees and severe hyperkalemia, he had undergone embolectomy of the right femoral artery and hemodialysis. Medical treatment for infective endocarditis was started after the first operation, because transesophageal echo cardiography revealed severe aortic regurgitation and massive vegetation of the aortic valve. Amputation of the right leg below the knee and of the left leg below the Lisfranc joint was performed after 19 days and aortic valve replacement with patch closure of a perivalvular abscess was performed one month after the first operation...

Integrated backscatter (IB) provides the quantitative assessment of left atrial spontaneous echo contrast (SEC). The IB intensity of the left atrial cavity relative to the left ventricular cavity is related to atrial thrombus in patients with atrial fibrillation (AF) or sinus rhythm. However, little is known about the relation between the quantitative SEC value of the left atrial cavity and variables implying thromboembolism in nonvalvular AF. To examine this relation, we performed transesophageal echo-cardiography with IB analysis in 65 patients with chronic nonvalvular AF...

A 75-year-old female, exhibiting epigastric pain and vomiting, underwent treatment for acute gastritis. She also experienced incontinence of urine and chest pain. A diagnosis of acute myocardial infarction was made upon examination of electrocardiographic findings and the patient was transferred to our hospital. Diffuse infarction of the left ventricle and acute aortic dissection (Stanford type A) were diagnosed by electrocardiographic and echo-cardiography. An emergency operation was performed. After induction of anesthesia, elevation of pulmonary artery pressure and fall of pulse pressure were observed, indicating acute cardiac tamponade...

BACKGROUND: Stroke is occasionally associated with ECG repolarization changes including ST depression. Recent evidence suggests a neurogenic contribution to these abnormalities in stroke patients. Animal studies implicate the insular cortex in cardiovascular control. We describe a patient with a left insular infarct and without cardiac or coronary artery disease, who developed ST depression indicating a neurogenic etiology. CASE DESCRIPTION: A 48 year-old female, with no risk factors for stroke, developed sudden expressive aphasia...

Twenty one cases of infective endocarditis in last 10 years were re-evaluated by Duke's criteria. Fourteen strains of Streptococcus viridans, 4 of Enterococcus faecalis, 1 of Haemophilus parainfluenzae were isolated from blood culture. As to the minimum inhibitory concentration (MIC) of 8 strains of Streptococci, imipenem revealed the lowest MIC value, following penicillin G, ceftriaxon not equal to ampicillin, vancomycin and gentamicin. One strain of them was penicillin-resistant (0.8 micrograms/ml). Serum inhibitory test (SIT) and serum bactericidal test (SBT) were undergone for 6 cases...

We evaluated three-dimensional transesophageal echocardiographic assessment of the implanted mechanical valves by rotational scanning method. Patients were 7 mitral valve replacement and one aortic valve replacement, 2 mitral and aortic valve replacement. In 2 cases of 7 mitral valve replacement, the prosthetic valve regurgitation was evaluated using by color Doppler echocardiography. In this study, multiplane transesophageal probe was used. It rotated at 2-degree intervals from 0 to 180 degrees and the three-dimensional reconstruction was performed by echo scan workstation system (TOMTEC Inc, Munich, Germany)...

Severe postoperative mitral regurgitation renders information on the underlying mechanism before reoperation very important, as a potential for mitral valve reconstruction may facilitate the decision whether to reoperate, especially in the very young. This study compares the efficacy of transthoracic echo-cardiography (TTE) and left-ventricular angiography with that of transesophageal echocardiography (TEE) for detection of the mechanism underlying mitral regurgitation and its quantitative assessment in children after repair of common atrioventricular septal defect...

Transesophageal echocardiography (TEE) is a useful clinical tool for the evaluation of a variety of cardiovascular lesions. In particular, TEE has been demonstrated to be a better diagnostic modality in the visualization of mechanical prosthetic heart valves than transthoracic echo-cardiography (TTE). Furthermore, TEE is noted to be particularly useful to evaluate the atrial surface of mitral prostheses, the usual location of thrombi or vegetations. We herein describe a patient with a dysfunctional St. Jude's mitral prosthesis resulting from an organized thrombus who underwent both TTE and TEE without visualization of the thrombus...

This study was undertaken to find a relationship between cardiac function indices and endocrine functions during prostaglandin E1 induced hypotension in surgical patients. Thirteen patients who underwent either orthopedic or gynecologic surgery were the subjects of the study. Systolic blood pressure decreased to 80 torr with prostaglandin E1 infusion (0.5-2 x min-1) under enflurane-N2O anesthesia. The cardiac function were judged by transesophageal echo-cardiography. Plasma ANP and ADH levels were measured by radioimmunoassay...
