Filter by:The goal of this interventional is to assess advantages of the ultrasound examination of the lungs in the early postoperative period in cardiac surgical patients after heart surgeries requiring cardiopulmonary bypass. Evaluation of pulmonary complications and outcomes during mid-term follow-up, as well as comparison of ultrasound examination and traditional roentgenologic methods (X-ray examination and CT of the chest) will be performed. The main question[s] it aims to answer are: - Is ultrasound examination of the lungs a more specific and sensitive method in identification of early postoperative pulmonary complications after on-pump cardiac surgical procedures, in comparison with traditional X-ray methods. - Does early identification of interstitial pulmonary edema (based on number of visualised B-lines in the early postoperative period), influences mid-term outcomes in this cohort of patients Participants will undergo ultrasound examination of the lungs on postoperative day 1, 3, 5 and 7 after heart surgery. Based on ultrasound findings and degree of interstitial pulmonary edema, medical (diuretics, anti-inflammatory, e.t.c) therapy will be modified. Researchers will compare this group of patients with control group, in which ultrasound examination will be performed in the same time frames, but no changes in medical management based on ultrasound findings will be made to see if timely administered medical therapy, based on ultrasound findings, can significantly improve symptoms, hospital lengths of stay and outcomes of this patients.
Mitral regurgitation (MR) and tricuspid regurgitation (TR) are common causes of breathlessness, fluid retention and other heart failure symptoms, which lead to reduced quality of life and frequent hospitalisation. These conditions are particularly prevalent in older adults with many of these patients being at high risk for surgical intervention due to frailty and comorbidities, leaving them with few treatment alternatives. Transcatheter edge-to-edge repair (TEER) procedures have increasingly been used to improve the severity of both MR and TR, offering patients symptomatic relief and reductions in heart failure hospitalisation at low procedural risk. There is considerable geographic variation in protocols to assess these patients prior to the procedure and also in length of hospital stay. The standard of care in the UK, and particularly in Oxford, emphasises fewer investigations before the TEER procedure and shorter length of hospital stay. This prospective, observational cohort study will examine the safety and feasibility of this practice.
To explore the impact of early transcatheter edge-to-edge repair of acute functional mitral regurgitation after myocardial infarction on the combined incidence of death and heart-failure associated hospitalisations at one-year follow-up, and quality of life and LV remodelling at two-year follow-up.
This observational study is to develop and validate the prediction model for functional mitral regurgitation regression in heart failure patients taking GDMT. The patients diagnosed ≥2+ functional mitral regurgitation by ultrasonic cardiogram are enrolled in this study and would be clinically followed by at least one year (clinical visit at 3 months, 6 months, and 12 months), and then by when the endpoints are reached.
To investigate to assess the severity of mitral regurgitation by multimodality imaging.
Study objectives: - To assess the impact of mitral valve surgery for mitral regurgitation on ventricular arrhythmic burden and surrogate markers of fibrosis in patients with arrhytmogenic mitral valve prolapse (MVP) from baseline to 6 months after surgery - To characterize the molecular landscape of arrhytmogenic MVP Study design: -Prospective explorative observational study Study population: -90 patients with arrhytmogenic MVP and without arrhytmogenic MVP (controls) eligible for mitral valve surgery for mitral regurgitation will be enrolled. All patients will be evaluated with cardiac magnetic resonance (CMR) imaging and continuous seven day arrhythmic monitoring before and at 6 months after mitral valve surgery
The CardioClip study is exploring the use of a wireless sensor to monitor pressure in the pulmonary artery. This sensor is inserted much like the mTEER procedure, a non-surgical method through a vein in the groin. The investigators want to find out if the sensor, by constantly sending information about heart function, can help improve patient outcomes. This means doctors could adjust medications based on real-time pressure changes detected by the sensor. The results from this study will help pave the way for future trials, asking if using these wireless sensors could benefit people with valve disease and heart failure.
This study aims to investigate the prevalence and characteristics of multiple and mixed valvular heart disease (MMVD), which includes combinations of stenotic or regurgitant lesions on cardiac valves. The research will be conducted as a multicenter observational study, involving several centers worldwide, and will have a one-year follow-up period (with a possible extension to 5 years). The primary aim is to determine the proportion of MMVD among patients evaluated for valvular heart disease. Secondary aims include the evaluation of the epidemiologic distribution of clinical, biological, and cardiovascular imaging characteristics at baseline, management strategies, and their impact on prognosis. The study will also evaluate clinical outcomes such as mortality, hospitalization for heart failure, and changes in echocardiographic parameters. This research aims to provide valuable insights into the diagnosis, management, and prognosis of MMVD, addressing an important knowledge gap in this area.
The goal of this multicenter, randomized, double-blind controlled study is to learn about the individuals after transcatheter edge-to-edge mitral valve repair (TEER). The main questions it aims to answer are: (1) can enhanced external counterpulsation (EECP) reduce the prevalence of afterload mismatch after TEER? (2) can EECP prevent the major adverse cardiac events after TEER? Participants will be randomly assigned into EECP or Sham-EECP intervention after TEER. Researchers will compare the EECP and Sham-EECP to see if it helps reduce the prevalence of afterload mismatch after TEER.
The aim of PLUTO-II is to use biventricular pressure-volume (PV) loop measurements to improve the understanding of direct changes in cardiac and hemodynamic physiology induced by transcatheter aortic valve implantation (TAVI) or tricuspid edge-to-edge repair (TEER). These procedures evoke immediate changes in cardiac mechanoenergetics, ventricular-vascular interaction as well as ventricular (in)dependency. Within the context of PLUTO-II, patients will undergo biventricular PV-loop measurements before and after TAVI or TEER. In future, the application of perprocedural PV loop monitoring may tailor the daily individual decision making process during structural interventions in the catheterization laboratory.
