Filter by:This prospective double blinded randomized study aims to compare the effect of inhaled versus intravenous milrinone on the pulmonary vascular resistance in patients undergoing mitral valve replacement surgery. The primary outcome is to determine change in pulmonary artery pressure. The secondary outcomes include, - Incidence of systemic hypotension. - Hemodynamic affection and need of vasopressors and inotropes. - Change in pulmonary vascular resistance versus systemic vascular resistance. - Right ventricular function. - Duration of mechanical ventilation. - Need for mechanical circulatory support devices. - Urine output - Length of intensive care (ICU) in stay. As the investigators hypothesize that inhaled milrinone has a selective pulmonary vasodilator effect devoid of the systemic hypotension with the intravenous administration.
Are there differences in outcome of mitral valve replacement with preservation of mitral apparatus among rheumatic and/or ischemic mitral lesions?. Mitral valve replacement with preservation of leaflets, and added coronary artery-bypass surgery, when indicated, is it a feasible and reproducible procedure?. The study was designed to compare outcome after prosthetic mitral replacement with preservation of mitral apparatus for rheumatic valve disease with outcome of replacement for ischemic myocardium and mitral valve disease, The outcomes will be guided by clinical assessment. and echo-cardiograph.
The evaluation uses ΔHb as an independent factor combined with artificial intelligence (AI) to predict its impact on the prognosis and blood transfusion of patients undergoing cardiac surgery, thereby guiding perioperative clinical blood use and improving patient prognosis.
The purpose of the study is to provide evidence of safety and effectiveness of the study valve. The rationale is to offer a replacement mitral valve for patients with anatomy that is too small for the currently commercially available valves ranging in size from 16mm to 37mm. 20 subjects were enrolled as part of the IDE cohort and an additional 3 were enrolled under continued access.
