Early Percutaneous Mitral Intervention in Asymptomatic Moderate Mitral Stenosis

Moderate Mitral Stenosis

Although percutaneous mitral commissurotomy (PMC) has been accepted as an effective treatment for symptomatic patients with moderate or severe mitral stenosis (MS), most asymptomatic patients are not candidates for PMC owing to the small but inherent procedure-related risks. Asymptomatic patients with MS show good survival rates up to 10 years, but there was a sudden deterioration precipitated by atrial fibrillation or embolism in half of the patients. Because the success rates of PMC were improved to more than 95% in ideal patients from highly selected centers and early PMC may decrease the occurrence of adverse events, such as atrial fibrillation or embolism, experienced centers tend to perform PMC at an early stage of disease. However, the potential benefits of early preemptive PMC in asymptomatic patients should be balanced against the real risks related to the procedure, and further studies of the efficacy of PMC in the prevention of embolism are necessary to extend its indications to asymptomatic patients. To the best of our knowledge, No randomized trials have been performed to ascertain the optimal timing of intervention in asymptomatic patients with significant MS. The early percutaneous MITral Intervention versus conventional manaGement in Asymptomatic moderate miTral stEnosis (MITIGATE) trial was designed to compare clinical outcomes of early intervention with those of a conventional management based on current guidelines in asymptomatic moderate mitral stenosis.

Surgical Ablation Versus No Surgical Ablation for Patients With Atrial Fibrillation Undergoing Mitral...

Atrial FibrillationMitral Valve Insufficiency1 more

The purpose of the research is to determine whether treating atrial fibrillation with surgical ablation during scheduled mitral valve surgery is better than mitral valve surgery by itself without the surgical ablation. Surgical ablation of atrial fibrillation is a technique used by surgeons to deaden atrial heart tissue and block electrical signals that may be causing your heart to beat irregularly. There are no new procedures being tested in this study; both mitral valve surgery and surgical ablation are used regularly in patients who have mitral valve problems and atrial fibrillation, although no surgical ablation devices have been approved by the Food and Drug Administration for the treatment of atrial fibrillation. What is not known with certainty, is whether patients with atrial fibrillation who are having planned mitral valve surgery would do better if they also had surgical ablation rather than medication alone to treat their atrial fibrillation.

The Effects of Levosimendan During Mitral Valve Surgery

Mitral Valve Stenosis With Incompetence or Regurgitation

The effects of levosimendan on renal function in patients with low ejection fraction undergoing mitral valve surgery will be investigated in a prospective, double-blinded, randomized clinical trial using serum creatinine (sCr)milligram in deciliter (mg/dL) values, calculated estimated glomerular filtration(eGFR)(ml/min/1.73 m2) rates and perioperative clinical follow-up parameters.

Teledi@Log - Tele-rehabilitation of Heart Patients

Heart FailureMyocardial Infarction3 more

The idea behind the Teledi@log consortium is to develop tele-rehabilitation concepts and technologies so that all types of heart disease patients, regardless of degree of severity, can be offered individual, customized and coordinated tele-rehabilitation across sectors. The project is innovative, breaking new ground in relation to existing national and international research projects in the area. The Teledi@log consortium sees its major task as developing and testing scenarios which can lead to a more coherent rehabilitation for heart patients in areas such as patient training, organization across the boundaries of the health system and using tele-rehabilitation technology. The Teledi@log consortium seeks to develop new tele-rehabilitation concepts which bring the patient closer to the health system and thereby promote the heart patient's rehabilitation, giving the patient and their families a more active role via new tele-rehabilitation technologies.The hypothesis of the study is that heart patients participating in a telerehabilitation program will have a higher quality of life compared to heart patients following traditional rehabilitation activities.

Bosentan for Severe Mitral Valve Dysfunction

SECONDARY PULMONARY HYPERTENSIONMITRAL STENOSIS2 more

Vasoconstrictive signaling via endothelin receptors is not limited to primary pulmonary arterial hypertension, but has also been documented in secondary pulmonary hypertension due to congestive heart failure, including cardiac valve disease. The investigators aim to examine the clinical and physiologic effects of bosentan therapy in patients with secondary pulmonary hypertension due to severe, inoperable cardiac valve disease, using a single-center, prospective, open-label, non-randomized study of oral bosentan in outpatients with severe mitral stenosis due to childhood rheumatoid fever. Primary end-point will be exercise capacity at six months determined by six-minute walking distance and cardiopulmonary exercise testing. Secondary end-points will be symptomatic relief, echocardiographic left ventricular function and pulmonary pressure, serum pro-brain natriuretic peptide, and adverse events at six months.
