REVIEW
Hui Chen, Yanling Zhao, Jianqun Yu
Right-sided cardiac valvular diseases have traditionally been considered less important than disease of mitral or aortic valve. However, severe tricuspid regurgitation could lead to right ventricle dysfunction and reduce patients' survival rate. In clinic setting, tricuspid valve disease should be paid more attention for patients with secondary tricuspid regurgitation caused by left-sided valvular surgery combined with irreversible annular dilatation increasing the risk of reoperation. In this review, we summarize the epidemiology, anatomy, pathology, diagnosis, ultrasound and cardiac magnetic resonance imaging findings in patients with tricuspid regurgitation...

To evaluate left atrial appendage (LAA) dysfunction using left atrial pulse-wave tissue Doppler imaging (PW-TDI) in acute cerebral embolism (ACE) patients with sinus rhythm (SR), transthoracic (TTE) and transesophageal echocardiograhy (TEE) were performed in 60 consecutive patients with SR without obvious left ventricular dysfunction within 2 weeks after ACE. Two groups were identified: LAA dysfunction [LAA emptying peak flow velocity (LAA-eV) <0.55 m/s, n = 20, age 65 ± 10 years] and without LAA dysfunction (LAA-eV ≥ 0...

INTRODUCTION AND OBJECTIVES: Today, the transcatheter treatment of atrial septal defects using an occluding device is a safe and effective therapeutic approach. Recently, intracardiac echocardiography has been developed as an alternative to transesophageal echocardiography for guiding these procedures. We describe our experience with intracardiac echocardiography during the percutaneous closure of atrial septal defects in adult patients. METHODS: This retrospective study involved 52 patients with atrial septal defects (77% with an ostium secundum defect and 23% with patent foramen ovale) who underwent transcatheter closure using an Amplatzer device under intracardiac echocardiographic guidance and without the need for general anesthesia or orotracheal intubation...

Fungal endocarditis is rare in comparison with bacterial endocarditis and is associated with a poor prognosis. Despite the proven reliability of echocardiography, false negatives are not uncommon and may influence the therapeutic strategy, as some reports have supported the efficacy of antifungal treatment alone. We report on a case of bioprosthetic aortic valve Candida parapsilosis endocarditis without typical echocardiograhy findings, which we treated with both antifungal and surgical therapy.

We present images observed in a patient with methicillin-resistant Staphylococcus aureus bacteremia from a hemodyalisis catheter and demonstrate the superiority of real time three-dimensional transesophageal echocardiography (RT3D-TEE) over 2D-TEE at identifying catheter-associated infected vegetations. Other studies have reported RT3D-TEE as an improved modality to identify and characterize intracardiac structures. However, to the best of our knowledge, there are no reports describing the specific characteristics of bacterial vegetations in a dialysis catheter...

The aim of our study was to assess the feasibility of a new image analysis, velocity vector imaging (VVI), in the assessment of left atrial volumes (LAV) and left atrial ejection fraction (LAEF). We retrospectively analysed 100 transthoracic echocardiographic findings in 71 men, and 29 women (mean age 57 +/- 19.8 years). Two subgroups of patients were defined: (1) with left ventricular (LV) EF > 50%, and (2) LV EF < 50%. For the VVI method of indexed LAV assessment we used the apical four-chamber view...

OBJECTIVE: The most significant complications seen in patients with obstructive sleep apnea syndrome (OSAS) are associated with the cardiovascular system. The present study assessed aortic stiffness in patients with OSAS and evaluated the effect of continuous positive airway pressure (CPAP) therapy on aortic stiffness. METHOD: Twenty-four patients with newly diagnosed, previously untreated, moderate or severe OSAS (apnea-hypopnea index > 15) and a control group of 17 healthy patients were included in the study...

Previous studies have suggested that the closure of the patent foramen ovale (PFO) may reduce or resolve migrainous symptoms, but ideal indications, devices and techniques are far from being identified definitively. A 21-year-old woman was referred to our center for evaluation of severe migraine (more than two attacks per week, > 6 h in duration, inability to work, direct relationship with Valsalva manouvre and effort, presence of aura), migraine disability assessment questionnaire (MIDAS) score of 42 and a large PFO with no atrial septal aneurysm: on transesophageal echocardiography and instrumental data suggesting a close relationship between migraine and PFO...

It is believed that directional coronary atherectomy (DCA) is more suitable than percutaneous transluminal coronary angioplasty for lesions such as severe eccentric lesions, ostial lesions, and branch lesions. However, it remains a fact that lesions that are also highly calcified are often suboptimal, since there may be difficulties such as in insertion of the housing and in sufficient cutting and removal. On the other hand, Rotablator is effective on calcified lesions, but afterward, dilation by balloon angioplasty for residual stenosis becomes necessary in many cases...

UNLABELLED: In diabetic heart disease myocardial, interstitial, coronary and neural structures are often involved. Coronary microangiopathy is supposed to contribute an essential part, which has not yet been clearly analysed. METHODS: In 9 normotensive patients with insulin-treated diabetes (DP) with clinically suspected coronary heart disease but normal epicardial coronary arteries, coronary microcirculation was studied. Coronary flow was determined as the quotient of base line and minimal coronary resistance after dipyridamole (0...

The authors document the importance of echocardiograhy (ECHO) with special respect to the pulsed Doppler technique (PDE) in the diagnosis of congenital heart diseases. Typical ECHO and PDE findings in atrial and ventricular septal defects, patent ductus arteriosus, valvular stenosis and insufficiency, absence of pulmonary valves, tricuspid and pulmonary atresia, Fallot's tetralogy, arterial trunk, double-outlet right ventricle, transposition of the great arteries, total anomalous pulmonary venous drainage and hypoplastic left-heart syndrome are described...

COMPARATIVE STUDY
R J Esper
In order to assess the sensitivity and specificity of the range-gated pulsed Doppler echocardiogram for the detection of aortic regurgitation, a study with use of this technique was carried out in 46 patients. They were classified into 3 groups: Group I was composed of 19 patients with a variety of heart diseases but with a competent aortic valve. Cardiac catheterization revealed no aortic regurgitation in any of the 19 patients, and the Doppler echocardiogram detected no turbulent diastolic flow in the left ventricular outflow tract...

A 42-year-old symptomatic woman with possible adult Williams's syndrome (mental retardation, 'elfin facies' and supravalvular aortic stenosis (SVAS)) is documented. This patient displayed many unique features in addition to the severe SVAS (peak systolic gradient 96 mmHg): there was an associated persistent left superior vena cava draining into the coronary sinus, mitral valve prolapse (Barlow's syndrome) and complete right bundle-branch block on ECG. Peripheral pulmonary artery stenosis was absent. M-mode echocardiograhy in the adult with SVAS is described for the first time in the literature, as is the use of the 60 degrees cross-sectional scan...

The electrocardiogrammes and echocardiogrammes of 10 weight lifters and 20 endurance trained top class athletes (runners, basket ball players and cyclists) were analysed. The electrocardiogrammes confirmed the notion of a specific profile in endurance trained athletes with left ventricular diastolic overload pattern. The echocardiogrammes did not show increased left ventricular wall thickness in the resistance trained athletes. It did show however a clear increase in left ventricular internal diastolic dimension and posteror wall thickness--the anatomical substratum of the large heart in athletes--in some categories of endurance trained athletes (cyclists and basket ball players)...
