Filter by:The goal of this clinical trial is to make clear that a new method, right ventricular outflow tract (RVOT) posterior septum pacing, has a greater accuracy in predicting the origin of ventricular outflow tract (VOT) ventricular arrhythmias (VAs) compared to the previous electrocardiographic standards for the identification of the origin of ventricular outflow tract. The secondary aim is to investigate, by using the new method, if it can optimize the procedure of radiofrequency catheter ablation. Researches will break the method of this investigation into two steps: First step have enrolled 100 patients. This step would be used to compare the results predicted by right ventricular outflow tract posterior septum pacing, with the previously used electrocardiographic criteria and actual target site. The second step will enroll another 100 patients. In this step, patients will be divided into two groups, one being the new protocol group and the other being the convention group. Patients will also be followed up, for 1 month and 3 months at outpatient clinic post procedure. Procedure time, success rate, fluoroscopy exposure time and complications, are compared between RVOT posterior septum pacing group and convention group.
The goal of this observational study is to evaluate the clinical characteristics of patients undergoing permanent cardiac pacing and to compare procedural efficacy and safety of different implantation approaches in the clinical practice of the participating centres. The contribution of non-fluoroscopic anatomical and electrophysiological reconstruction systems to device implantation procedures will also be evaluated. Participants [patients over 18 years old with an indication to receive a definitive pacemaker/intracardiac defibrillator implant] will receive a permanent cardiac pacing implant as requested according to European Society of Cardiology (ESC) guidelines; the investigators will evaluate procedural efficacy and safety of different implantation approaches.
Postural Orthostatic Tachycardia Syndrome (POTS) affects approximately 500,000 - 3 million Americans. This number will only increase due to the large number of patients experiencing POTS due to "long COVID." POTS patients experience several symptoms, including tachycardia, palpitations, dizziness, and pre-syncope or syncope, among others. POTS can be very debilitating and not only affect patients physically but also emotionally and financially. It takes an average of four years and seven doctors for POTS patients to achieve a diagnosis and it is often a frustrating and negative experience fraught with misdiagnoses, stigma, and depression and anxiety. Recent research demonstrates that mHealth technology may be one way that POTS patients can improve their experience in the healthcare system by providing objective data to their healthcare providers. Patients may also better take care of themselves through symptom monitoring and instant patient education via mHealth technology. The two study aims are: 1) Developing a mHealth app to improve the delay to diagnosis and the quality of life of POTS patients; and 2) Evaluate the usability and feasibility of the mHealth app and study design. To achieve these aims, researchers in this study will work with a programmer and leaders from the mHealth Application Modernization and Mobilization Alliance (MAMMA) and stakeholders (patients, caregivers, and providers) to co-design a mHealth app for POTS patients, including key educational components guided by the IDEA model, an instructional risk communication approach. A group of diagnosis-seeking POTS (n=20) patients will pilot test the app and provide feedback for improvement as well as evaluate its usability. Results from this study will allow researchers to acquire necessary data to apply for external funding to conduct a larger clinical trial to evaluate its influence on health outcomes, such as patient experience during visits with physicians, perceived stigma, and time to diagnosis.
This is a multicenter, interventional study. The study will enroll patients that fulfill the inclusion criteria over a 33-month period. Considering the small number of patients who will meet the study criteria, it is also possible to include retrospective patients who already underwent STAR (for instance, as part of a compassionate program) if they meet all the inclusion and exclusion criteria as well as the treatment planning standardized requirements and sign their consent to this trial. All patients prospectively enrolled will undergo a flow of investigations following a standardized approach. ICD programming will be standardized.
This is an observational study to deeply phenotype the disorder of POTS using multiple testing modalities.
The value of phenylephrine administration in response to tachycardia in preventing hypotension after spinal anesthesia in elective cesarean section.
The goal of this Interventional clinical trials in atrioventricular reentrant tachycardia patients. The main question it aims to answer whether non-invasive vagus nerve stimulation could be effective in restoring rhythm. Patients will receive non-invasive vagus nerve electrical stimulation under catheter evoked and cardiac monitoring to observe their heart rhythm changes.
This study is a first-in-human, prospective, multi-center, pre-market single-arm clinical trial to evaluate the Future Cardia™ ICM.
This is a pilot dose-finding study to test the hypothesis that mirabegron increases systolic blood pressure (BP), prevents syncope/presyncope, and improves the quality of life (QOL), functional capacity, chest pain, and overactive bladder (OAB) symptoms in patients with postural orthostatic tachycardia syndrome (POTS) who have a documented history of hypotension inadequately responsive to conventional treatments. The American Heart Association funds this study.
The goal of this study is to understand the effects of early mobilization after a Z stitch procedure in patients undergoing certain heart-related treatments. The investigators want to find out if allowing patients to move around sooner after their procedure can improve their satisfaction and potentially lead to earlier discharge from the hospital. Type of Study: Clinical Trial Participant Population/Health Conditions: Patients aged 18-99 undergoing specific heart procedures such as atrial fibrillation treatment, atrial flutter treatment, supraventricular tachycardia treatment, diagnostic electrophysiology studies, AV node ablation, or Watchman device placement. Main Questions: Does early mobilization (getting up and moving around sooner) after the Z stitch procedure improve patient satisfaction? Participants will be divided into two groups, and researchers will compare those who have one hour of bedrest with those who have four hours of bedrest after the Z stitch procedure. The investigators want to see if the shorter bedrest period leads to higher patient satisfaction.
