Filter by:Heart failure (HF) is a condition in which the heart cannot pump blood adequately. It is increasingly common, consumes 4% of the UK National Health Service (NHS) budget and is deadlier than most cancers. Early diagnosis and treatment of HF improves quality of life and survival. Unacceptably, 80% of patients have their HF diagnosed only when very unwell, requiring an emergency hospital admission, with worse survival and higher treatment costs to the NHS. This is largely because General Practitioners (GPs) have no easy-to-use tools to check for suspected HF, with patients having to rely on a long and rarely completed diagnostic pathway involving blood tests and hospital assessment. The investigators have previously demonstrated that an artificial intelligence-enabled stethoscope (AI-stethoscope) can detect HF in 15 seconds with 92% accuracy (regardless of age, gender or ethnicity) - even before patients develop symptoms. While the GP uses the stethoscope, it records the heart sounds and electrical activity, and uses inbuilt artificial intelligence to detect HF. The goal of this clinical trial is to determine the clinical and cost-effectiveness of providing primary care teams with the AI-stethoscope for the detection of heart failure. The main questions it aims to answer are if provision of the AI-stethoscope: 1. Increases overall detection of heart failure 2. Reduces the proportion of patients being diagnosed with heart failure following an emergency hospital admission 3. Reduces healthcare system costs 200 primary care practices across North West London and North Wales, UK, will be recruited to a cluster randomised controlled trial, meaning half of the primary care practices will be randomly assigned to have AI-stethoscopes for use in direct clinical care, and half will not. Researchers will compare clinical and cost outcomes between the groups.
Functional tricuspid regurgitation (FTR) remains a common finding in patients with left-sided valvular heart diseases especially mitral valve regurgitation or stenosis. It is mainly caused by dilatation and flattening of the tricuspid valve (TV) annulus as a result of right ventricular (RV) enlargement and is inevitably affected by the RV function. Multiple studies support the better outcome of using rigid ring annuloplasty over suture repair for treating FTR in concern with the durability and freedom from residual regurgitation. These studies refer the superiority of rigid ring annloplasty to the three-dimensional configuration achieved by such rings which matches the normal tricuspid annulus and, at the same time, to the rigid support of the annulus. On the other hand, other studies support the use of flexible prosthetic bands like Dacron or polytetrafluroethilin (PTFE), especially over suture techniques, due to their easy applicability and availability with good postoperative results. Therefore, suture annyloplasty became nowadays less convenient for FTR repair since both flexible bands and rigid rings appeared to offer good midterm outcomes in recent meta-analysis studies. However, the ideal annuloplasty method for repairing FTR is still debatable between the three-dimensional (3D) rigid rings versus flexible prosthetic bands. In this retrospective comparative study, we share our experience with flexible fashioned bands in FTR.
Cardiovascular diseases (CVD) are a group of illnesses that include coronary heart disease, cerebrovascular disease, congenital heart disease, and deep vein thrombosis. CVD is the leading cause of mortality worldwide, representing 31% of deaths. In Spain, CVD caused 24% of all deaths in 2020. Major surgery is often chosen as the treatment of choice for CVD. The concept of fast-track rehabilitation after surgery appeared in the 1970s. Participation in these exercise-based prehabilitation programs may decrease postoperative complications and length of hospital stay. The purpose of the present study is to evaluate whether the implementation of an additional resistance training (RT) prehabilitation protocol within a cardiac exercise-based prehabilitation can reduce ICU length of stay, postoperative complications, and hospital length of stay (LOS). Additionally, the secondary objective is to determine whether a program that includes RT in addition to respiratory and aerobic training can have better effects on ventilatory variables. This study follows the protocol of a prospective, parallel, non-randomized clinical trial. Ninety-six adult patients diagnosed with valvular pathology and who have been scheduled for surgery will be included. The control group will be treated with ventilatory and strengthening of respiratory muscles, as well as aerobic exercise. The experimental group, in addition, will receive RT targeting peripheral muscles. Variables such as hospital stay, quality of life, respiratory values, and exercise capacity will be evaluated. Quantitative variables will be analyzed using a t-test or ANOVA, or Mann-Whitney test if the distribution is non-parametric.
The purpose of this study is to clarify the changes of neurocognitive function of patients undergoing cardiac valve disease before and after surgical treatment under cardiopulmonary bypass operation, and to predict the neurological prognosis of such patients through combined imaging technology, so as to improve and avoid the occurrence of postoperative neurological dysfunction in such patients.
To collect information about the management of symptomatic severe Aortic Stenosis (AS) and Aortic Regurgitation (AR) using transcatheter aortic valve replacement (TAVI).
The research will be carried out in the Cardio Vascular Surgery (CVS) Intensive Care Unit (ICU) of Ankara Training and Research Hospital (TRH) . Patients will be divided into two Experimental (n=24) and control (n=24) groups. Simple randomization method will be used in the study, provided that there are equal numbers of male and female patients in the experimental and control groups, regardless of the age of the patients. Patients in the experimental group will use a digital window. The "Patient Information Form","Richard-Campbell Sleep Questionnaire_RCSQ " and " Day and Night Perception Form" will be used in the data collection phase. Ethics committee approval was received from Ankara Yıldırım Beyazıt University Ethics Committee in order to conduct the study.
Robotic surgery is one of the most popular minimally invasive procedures for patients with coronary artery disease or valvular diseases. Studies have shown that, as compared to conventional sternotomy, patients underwent robot-assisted bypass grafting or valvuloplasty had less post-operation pain, blood transfusion volume during operation, re-operation rate, post-operation stroke rate and length of hospitalization. However, most studies focused on the comparison of complications of different procedures, and the investigation of cardiopulmonary function recovery is still lacking. Thus our study is to compare the functional outcomes between patients that undergo different surgical procedures.
Safety and performance evaluation of the NeoChord Transcatheter Mitral Repair System in patients with degenerative mitral valve regurgitation.
Prospective Study, Single Arm to evaluate the safety and efficacy of polyurethane expandable valve implantation in the pulmonary position, in 5 patients over 18 years of age, with pulmonary valve dysfunction and moderate to severe impairment of Right Ventricular function. During throughout the study, safety parameters related to valve operation will be evaluated (patient's Functional Class), in addition to the occurrence of Serious Adverse Events. After the procedure, the patient must be hospitalized in the Intensive Care Unit until the complete hemodynamic stabilization and normalization of lung function and in good general condition (2 to 3 days of stay) and then transferred to the ward (2 to 3 days and stay) before hospital discharge. A formal Statistical Analysis Plan (SAP) will be developed and finalized before closing the database. Full details of data presentations and analysis will be provided in SAP. Additional statistical analyses, other than those described in this section, may be performed if deemed appropriate and included in SAP. Any deviations from the final analysis plan or what is presented in the protocol will be discussed in the final study report. No formal inferential statistics will be applied to the data collected in the study.
