a ruptured sinus of valsalva aneurysm rarely accompanies the aortic and tricuspid valve endocarditis. a 36-year-old woman presented with low-threshold dyspnea on exertion and fever. transthoracic and transesophageal echocardiography showed a ruptured noncoronary sinus of valsalva aneurysm with large vegetations on the tricuspid and aortic valves, resulting in moderately severe tricuspid regurgi...

Continuous flow left ventricular assist devices (CF-LVADs) are miniaturized supporting the failing ventricle and alter blood in cardiovascular system which may cause severe health complications. Regurgitation stenosis mitral aortic valves further aggravate complications limit efficiency of CF-LVAD support. Within this context, real-time monitoring support will allow early detection valve proble...

OBJECTIVES This study examined the association between the presence of tricuspid regurgitation and immediate and late adverse outcomes in patients undergoing balloon mitral valvuloplasty. BACKGROUND Significant tricuspid regurgitation has an adverse impact on morbidity and mortality in patients undergoing mitral valve surgery for mitral stenosis. METHODS We studied 318 consecutive patients ...

OBJECTIVE To investigate the new onset of mitral regurgitation in patients with otherwise normal echocardiograms after anthracycline treatment and to assess its relation to other selected indicators of myocardial damage. DESIGN Prospective echocardiographic and electrocardiographic study. SETTING Tertiary paediatric cardiac referral centre. PATIENTS 305 patients, aged 2-33 years (median 1...

The incidence and severity of catheter-induced tricuspid regurgitation has not been studied extensively. Given the frequency with which right heart catheters are employed to measure cardiac output, it is important to know whether the severity of catheter-induced tricuspid regurgitation is sufficient to invalidate the measurement of thermodilution cardiac output. Accordingly, the purpose of the ...

Indices have been developed that provide an improved means for evaluation of the degrees of severity of mitral stenosis and regurgitation. The severity of anatomic mitral valve disease found at surgery or autopsy was considered to be the determinant of the state of the valve. An index of the time for the diastolic atrioventricular pressure gradient to fall to half its value multiplied by 100 an...

BACKGROUND Bicuspid aortic valve regurgitation can be caused by a defect in the valve itself or by dysfunction of one or more components of the aortic root complex. A successful repair thus requires correction of all aspects of the problem simultaneously. We review our experience addressing both the valve and the aortic root when correcting bicuspid valve regurgitation. METHODS AND RESULTS Be...

OBJECTIVE To determine the likelihood ratio for trisomy 21 in fetuses with tricuspid regurgitation at the 11 to 13 + 6-week scan. METHODS Fetal echocardiography was carried out by specialist pediatric cardiologists in 742 singleton pregnancies at 11 to 13 + 6 weeks' gestation and pulsed wave Doppler was used to ascertain the presence or absence of tricuspid regurgitation. To avoid confusion w...

To determine whether left ventricular (LV) end systole and end ejection uncouple in patients with long-term mitral regurgitation, 59 patients (22 control patients with atypical chest pain, 21 patients with aortic regurgitation, and 16 patients with mitral regurgitation) were studied with micromanometer LV catheters and radionuclide angiograms. End systole was defined as the time of occurrence (...
