background: gastroesophageal reflux disease (gerd) is one of the most prevalent disorders affecting gastrointestinal tract with a wide range of frequency around the world. in this study, we aimed to review all of the published studies about gerd’s prevalence in iran systematically. methods: we searched bibliographic databases including pubmed and google scholar and local databases (scientific i...

conclusions surgical repair of the congenital mv disease yields acceptable early and intermediate-term satisfactory valve function and good survival at intermediate-term follow-up. strong predictors for poor surgical outcome and death were age smaller than 1 year, weight smaller or equal than 6 kg, and associated cardiac anomalies such as pulmonary stenosis. objectives the aim of this study was...

We evaluated 147 patients with adequate color Doppler and angiographic studies for mitral regurgitation. Sixty-five patients had no mitral regurgitation by both color Doppler and angiography and 82 patients had mitral regurgitation by both techniques. Thus the sensitivity and specificity of color Doppler for the detection of mitral regurgitation was 100%. Three two-dimensional echocardiographic...

Background. The ability of transesophageal color Doppler echocardiography to provide high-resolution images of both cardiac structure and blood flow in real time is advantageous for many clinical purposes. This study was performed to determine the utility of the regurgitant jet width at its origin measured by transesophageal Doppler color flow imaging in the assessment of severity of mitral reg...

soon after cardiac transplantation, but the recipient patients seldom show a postoperative precordial murmur attributable to valve dysfunction. This is not surprising, because mild forms of valvular regurgitation detected by Doppler are often clinically inaudiblee5 Overt signs of tricuspid regurgitation and right ventricular failure were observed in 2 patients with residual postoperative pulmon...

BACKGROUND Quantitation of valvular regurgitation remains a challenge. The accuracy of quantitative Doppler is controversial, and its ability to measure regurgitant volume is unknown; therefore, it is not widely used. METHODS AND RESULTS In 120 patients (20 without regurgitation, 19 with aortic regurgitation, and 81 with mitral regurgitation), the stroke volume through the mitral annulus and ...

BACKGROUND To introduce a new technique to create a pulmonary valve biorifice for the reconstruction of the right ventricular outflow tract in tetralogy of Fallot (TOF), and to summarize the initial clinical experiment. METHODS The new technique of reconstructing the right ventricular outflow tract with pulmonary valve biorifice was used in 53 cases of TOF (the observation group). While the c...

Fifty patients with aortic and/or mitral regurgitation underwent gated pool imaging and cardiac catheterisation to quantify the severity of valvar regurgitation. Gated pool imaging was performed in the left anterior oblique projection and an estimate of regurgitant fraction derived by comparison of the left ventricular to right ventricular stroke volume expressed as a ratio. In 17 normal subjec...

In this issue of JACC: Cardiovascular Interventions, Nombella-Franco and the Quebec Heart and Lung Institute (1) report their experience with balloon post-dilation in patients with residual paravalvular aortic regurgitation after transcatheter heart valve (THV) implantation. Paravalvular regurgitation grade 2 was documented by transesophageal echocardiography in approximately one-third of their...
