Filter by:The Melody valve has historically been used for pulmonary valve replacements; however it has been more recently used in the mitral and tricuspid positions. This multi-center, retrospective, observational study will review the durability of the Melody valve inserted into the mitral or tricuspid positions. Patients who have undergone Melody valve insertion into either the mitral or tricuspid positions prior to December, 2014 will be eligible for the study. Basic de-identified patient demographics will be collected as well as select clinical data. Ventricular function and valvar function of the affected valve will be retrospectively reviewed both prior to surgery and following, as well as review of operative data. The investigators will also review the most recent follow up data and any subsequent re-interventions on the Melody valve. Data from all sites will be entered into an external REDCap database, using only de-identified data.
The purpose of this study is to determine whether Sildenafil is effective in the treatment of sustained pulmonary artery hypertension after corrected mitral valve disease.
Surgical treatment is the only approach with potentially defined clinical success for organic mitral valve (MV) regurgitation. Recurrent or persistent complaints after initial successful MV repair is a clinical challenge in current practice. Especially when echo parameters at rest are within or near normal ranges and patients presenting disproportionately symptomatic in relation to the observed results. However, while MV regurgitation is a hemodynamic disease, currently used 2-dimensional (2D) transthoracic echocardiography (TTE) at rest lacks information about hemodynamic changes. Physical stress echocardiography is a promising technique to complement nowadays rest TTE in order to improve interpretation of hemodynamic changes. However, normal values for exercise echo are lacking in this postoperative patients cohort. A prospective, observational trial to determine normal values in stress echocardiographic parameters in asymptomatic patients after successful MV repair for organic MV regurgitation, is therefore highly needed. Purpose of the SEP- study is to determine normal values in stress echocardiographic parameters in asymptomatic patients at least 6 months after successful MV repair for organic MV regurgitation. These normal values for stress echo are of utmost importance to correctly and accurate interpret stress echo results during postoperative follow-up and to improve clinical decision making in patients post MV repair.
The purpose of this study is to compare early mitral valve repair versus a watchful waiting strategy in asymptomatic patients with severe organic mitral valve regurgitation and preserved left ventricular function.
The purpose of this study is to examine the wound infusion of articaine for treatment of acute post-sternotomy pain in a placebo-controlled manner using a prospective and randomized design and an active control (bupivacaine)
