Filter by:This study seeks to investigate the clinical value of novel echocardiographic indices, including myocardial work parameters, during the acute phase of heart failure hospitalization. The trajectory of novel echocardiographic indices from the start to the end of hospitalization will be captured, as a means to unravel and subsequently better understand the diverse pathophysiology of different phenotypes of the heart failure continuum. Correlation between novel echocardiographic indices with clinical data, biochemical data, different heart failure phenotypes, and therapeutic maneuvers will be attempted. Prognostic implications of those indices will be explored.
Heart Failure and valvular heart disease are disproportionate problems in rural and remote Australia (RRA). Echocardiography is the best imaging investigation, and essential for management, but access to this essential test shows huge geographic variations, primarily because of dependence on expert acquisition. This trial seeks to demonstrate the effectiveness of artificial intelligence-based echocardiography for triage and management of patients with known or suspected heart disease in RRA.
Valvular heart disease (VHD) is a growing and important public health problem due to the increasing prevalence of degenerative VHD, accompanied by prolonged life expectancy in developed countries. It is associated with high morbidity and mortality.Heart valve surgery is one of the proven treatments of VHD, which corrects hemodynamic abnormalities that could contribute to decrease mortality and improvement in quality of life, despite the improvement in the hemodynamic parameters, the cardiorespiratory fitness level remained low after heart valve surgery. Cardiac surgeries can cause a series of clinical and functional complication. Postoperative pulmonary complications are the most common, in turn, contribute directly to increase morbidity and mortality and longer hospital stays.Mucociliary clearance is affected after open-heart surgery by the effects of general anaesthesia, intubation and analgesia. Expiratory flow rate is directly related to lung volume and therefore when lung volumes are decreased, coughing will be less effective. Chest physical therapy plays an important role in the prevention and management of postoperative pulmonary complications. It includes deep breathing exercises, mobilization, postural drainage, percussion and vibration or shaking which were developed to improve bronchial drainage. Airway clearance techniques are commonly used for clearing secretions, improving gas exchange, oxygenation, and work of breathing. Acapella® is an airway clearance device that combines the resistive features of a positive expiratory pressure device with oscillations which diminishes the mucus adhesiveness and decrease the collapsibility of airways. In the present study, the aim is to compare the effect of acapella and incentive spirometer on cardiopulmonary fitness in patients undergoing heart valve surgery. Those patients may gain a more benefit from acapella application and incentive spirometer so, prevent post-operative pulmonary complication, reduce hospitalization and hospital costs, and improve quality of life. Therefore, early mobilization and chest physiotherapy including acapella and incentive will be started on 1st day after discharge from cardiac care unit (CCU) .
Paraprosthetic cardiac valve leaks are a progressive complication after after surgical or percutaneous heart valve replacement. These leaks can lead to heart failure and/or life-threatening hemolysis. Percutaneous closure of para-prosthetic leaks has been developed as an alternative to surgery in high-risk patients. These procedures remain technically challenging with a significant risk of failure and complications, but this risk is improved since the development of dedicated prostheses and the increased experience of the operators. The data in the literature concerning percutaneous leak closure remain limited and disparate and mostly retrospective.The impact of the procedures on the quality of life of patients is not known. Beyond the technical aspects and the follow-up of major cardiovascular events, investigators also wonder what is the impact of these procedures on the quality of life of patients. Investigators hypothesize that even a partial reduction in paraprosthetic leakage may be associated with an improvement in quality of life through reduction of transfusion needs and/or reduction of dyspnea. A prospective study is warranted to assess the technical and clinical and clinical results of these procedures, together with the evaluation of the the possible benefit on the quality of life of the patients.
The study aim is to test the diagnostic performance of internists interpreting echo images aided by the AISAP CARDIO V0.7 diagnostic support system. Ground truth will be established by an interpretation by cardiologists specialized in echo, of the same POCUS images (acquired by the internist \ sonographer ). Up to 1000 subjects; Study population will be distributed according to the following schema: Group 1 -up to 800 patients hospitalized in the Internal Medicine division Group 2 - up to 200 patients hospitalized in the acute Geriatric division
The Bronx-Valve Registry is designed to collect and assess data on all patients with valvular diseases referred to Montefiore Medical Center for echocardiographic exams.
Transcatheter aortic valve replacement (TAVR) has became an important treatment of severe aortic stenosis (AS). Several randomized clinical trials showed that TAVR was non-inferior or superior to surgical aortic valve replacement (SAVR). However, many different issues have emerged: TAVR in younger patients? valve leaflet thrombosis? transcatheter valve durability? coronary reaccess after TAVR? TAVR in bicuspid aortic valve? TAVR in aortic regurgitation? etc. Hence, a prospective, multicenter database is created to provide the real-word data for these questions.
NPs can be used To detect subset of asymptomatic with subtle LV dysfunction for further evaluation and earlier referral for intervention and its correlation with echocardiographic finding.
Considering decrease of major complications and improvement of procedural results, conductive disorders currently remain the main issue after TAVR (Transcatheter aortic valve replacement). While pacemaker implantation rate was about 10-15%, new onset LBBB (Left bundle branch block) was observed in 30 % of patients after TAVR but resolved at discharge in the majority of them, with less than 20% progressed to complete AV (atrioventricular) block requiring permanent pacing at hospital discharge. Higher implantation and improvement of the devices were associated with decline of pace maker implantation rate over the years in experienced teams. While guidelines do not give definite recommendation regarding conductive disorder management and pacemaker indication, a strategy of selective telemetry monitoring (TM) after TAVR according to the risk of conductive disorders may be proposed to limit indication and lenght of stay of intensive care unit admission (ICU), allowing direct admission of lower risk patients in general cardiology ward (GCW) without TM, to decrease the duration of TM when a conductive disorder is stable or regressive and finally to decrease the rate of pacemakers implantation. Potential benefit may also include limitation of ICU overload in high volume TAVR centers, investigators can also expect shorter hospitalization duration, with potential economic impact, in line with the development of algorithms for fast track procedures. Therefore the main objective of our prospective study was to evaluate feasibility and safety of a strategy of management of conductive disorders after TAVR based on an algorithm of diagnosis, monitoring and therapeutic strategies based on ECG analysis.
