Filter by:Single center, randomized trial (1:1 fashion) to asses the safety and the feasibility of the ultrasound guided venous puncture vs standard fluoroscopic technique in patients undergoing pacemaker or implantable cardioverter-defibrillator implantations.
Lung cancer surgery causes significant changes in the small circulation as well as changes in the intrathoracic anatomy. The effects of lung cancer surgery on electrocardiography and the cardiac stress associated with the procedures have not been previously extensively studied. The aim of the present study is to ascertain whether modern mini-invasive lung cancer surgery causes changes in the electrocardiogram, and whether these changes are transitory during short-term follow-up. Furthermore, the study aims to describe whether lung cancer surgery causes significant cardiac stress detectable by intraoperative electrocardiography.
Phase I: For the Phase I portion, there will be up to 15 patients treated with SABR and followed for 6 months post-treatment to ensure no significant acute grade 3 or 4 toxicity from SABR treatment. Efficacy as defined below will also be assessed. Following this Phase I lead-in, results will be presented to the FDA for review. Only upon favorable analysis by the FDA committee, and with written explicit permission, will the Phase II randomized portion ensue. This is to act as a safety and efficacy safeguard and has is addressed more thoroughly in the Statistical Analysis Plan of this protocol. Phase II: A 1:1 randomized Phase II portion with 25 patients in each arm assigned to SABR or current practice (standard of care; Figure 3). Standard of care is defined as nationally recognized appropriate next treatment strategies for medical and catheter-ablation refractory structural cardiac VT that is assessed and judged appropriate for the patient by his/her treating cardiologist. This includes repeat catheter ablation (intravascular and/or epicardial catheter ablation), placement of left-ventricular assist device (LVAD), heart transplant, or further medical management (e.g. antiarrhythmic drug modulation/continuation). Randomization will be performed through the Clinical Trial Conduct (CTC) website.
The aim of this demonstration project is to create an additional access point in the community at local pharmacies for atrial fibrillation screening, detection, and referral to physicians for follow-up and initiation of evidence-based therapy when appropriate.
Unicenter, 1:1 randomized, open-labelled clinical trial comparing left atrial flutter ablation using high density mapping or strict lineal ablation. Main outcome: arrhythmia recurrences over 1 year follow-up with daily 1-lead 30 seconds ECG samples.
The study is designed to collect data on Cardiovascular Implantable Electronic Device (CIED) information, implant procedure details, and/or patient characteristics to support development of future CIED products and procedures.
AliveCor (www.alivecor.com) has developed an ECG device (KardiaMobile) that interfaces with iOS and Android smartphones and tablets. This ECG consists of a lightweight hardware case with two metal electrodes that can snap onto the back of the phone and a software application. By holding the right finger(s) on the right electrode and the left finger(s) on the left electrode, an electrical circuit is completed and a lead-I, 30 second rhythm strip is created. KardiaMobile and a newer device, KardiaMobile 6L, were approved by FDA for ECG rhythm recording. Recently, AliveCor developed two new devices: Kardia 12L and Kardia 6L to record 12- lead and 6-lead ECGs, respectively. However, the data generated from the two new devices have not yet been validated for accuracy. The purpose of this study is to evaluate the accuracy of the ECGs recorded by AliveCor Kardia 12L and 6L devices. This will be compared to simultaneous standard of-care 12-lead ECG recordings. The ECGs will be analyzed for accuracy and statistical difference using root-mean-square error and cross correlation between the median beats.
Prolonged prone position ventilation reduces the 30-day mortality in acute respiratory distress syndrome (ARDS) and in COVID-19 infection. A large number of patients with COVID-19 suffered from new-onset cardiac disease, therefore, ECG is crucial. However, there is limited data on the effects of prone position on the ECG in COVID-19 patients.
To investigate the effect of VTA ablation at the time of LVAD implant to see if it can reduce the incidence of VTA after surgery
In this patient engagement study, patients and partners will attend a presentation, group meeting and responding to the survey to help the research team gage the acceptability of using a biological therapy to prevent cardiac arrhythmia. Patient Partners will also help to clarify which outcomes are important to patients, to ensure the selected outcomes align with patient interests.
