STAR Apollo Mapping System is an FDA cleared mapping technology that can analyze the signals collected during the ablation procedure on the 3D mapping system and give the physician further insight into the AF activation patterns which may assist them in identifying areas responsible for maintaining Atrial Fibrillation (AF). The STAR Apollo Mapping System system allows clinicians, after treating the Pulmonary Veins (PV), to collect data from the atria during clinical AF procedures using standard FDA cleared catheters and devices. This study aims to examine the impact of the STAR Apollo Mapping System on procedural and acute outcomes in a multicenter observational study.
The aim of this study is to investigate whether renal denervation can reduce arrhythmia burden in patients with recurrent, paroxysmal atrial fibrillation despite durable pulmonary vein isolation.
Atrial fibrillation (AF) is the most common arrhythmia, which leads to reduced cardiac output and promotes the occurrence of heart failure, and abnormal hemodynamic changes in the left atrium induce thrombosis, which seriously reduces the quality of life, and even leads to death. For patients who need cardiac surgery combined with the Cox-Maze IV (CMIV) surgical ablation, oral amiodarone postoperatively for three consecutive months was recommended as the preferred treatment option. However, the study found there were still 15%-35% of patients at risk of AF recurrence. Dapagliflozin, a sodium-glucose cotransporter 2 inhibitor, has been widely used for the treatment of type 2 diabetes mellitus and heart failure. Nonetheless, it remains unknown whether dapagliflozin can improve the recurrence of AF and reduces adverse cardiovascular events for patients who need CMIV ablation, and whether it can be routinely used for AF patients without diabetes or heart failure. Therefore, this study aims to explore the effect of postoperative oral dapagliflozin on the recurrence of AF after CMIV.
The primary objective of this study is to collect real-world data on WATCHMAN FLX™ Pro Left Atrial Appendage Closure (LAAC) Device in patients with non-valvular atrial fibrillation.
Current, worldwide assessments of the prevalence of AF estimate that 33 million people are affected by this cardiac arrhythmia. As the most common sustained atrial arrhythmia, AF has a well-established association with systemic embolic events, stroke, heart failure, and increased mortality. Current treatment guidelines and consensus statements for patients with AF suggest that most patients should be first managed with a pharmaceutical drug therapy; however, when a patient becomes drug refractory (intolerant or non-responsive), catheter ablation by PV isolation (PVI) is recommended. The aim of PVI is abolishment of all conducted electrical activity beyond the isolating lesions. The recent NICE guidelines have established that today RF point-by-point ablation is the most cost-effective treatment approach over a lifetime after failure of 1 or more anti-arrhythmic drugs5, but until now a new technology, HELIOSTAR, RF Balloon, has not been included in this cost-effectiveness analysis
Non-valvular atrial fibrillation (NVAF) increases the risk of stroke by three- to five-fold, especially in elderly patients, creating a huge burden on medical system as well as a negative impact on patients' lives. Direct oral anticoagulants (DOACs) are recommended for patients with NVAF to prevent strokes. Real world data reveal the underuse of anticoagulation in the elderly, especially due to physicians' concern of bleeding, often neglecting the thromboembolic risk. This study is designed to evaluate the safety and effectiveness of edoxaban in Korean elderly patients with atrial fibrillation.
This study aims to analyze the safety and effectiveness of the discontinuation/resumption protocol of factor Xa inhibitors before and after invasive procedures/surgeries in non-valvular atrial fibrillation patients who are at risk of minor bleeding in actual clinical settings
Atrial Fibrillation (AF) is an abnormal heart rhythm. Because AF is often asymptomatic, it often remains undiagnosed in the early stages. Anticoagulant therapy greatly reduces the risks of stroke in patients diagnosed with AF. However, diagnosis of AF requires long-term ambulatory monitoring procedures that are burdensome and/or expensive. Smart devices (such as Apple or Fitbit) use light sensors (called "photoplethysmography" or PPG) and motion sensors (called "accelerometers") to continuously record biometric data, including heart rhythm. Smart devices are already widely adopted. This study seeks to validate an investigational machine-learning software (also called "algorithms") for the long-term monitoring and detection of abnormal cardiac rhythms using biometric data collected from consumer smart devices. The research team aims to enroll 500 subjects who are being followed after a stroke event of uncertain cause at the Emory Stroke Center. Subjects will undergo standard long-term cardiac monitoring (ECG), using FDA-approved wearable devices fitted with skin electrodes or implantable continuous recorders, and backed by FDA-approved software for abnormal rhythm detection. Patients will wear a study-provided consumer wrist device at home, for the 30 days of ECG monitoring, 23 hours a day. At the end of the 30 days, the device data will be uploaded to a secure cloud server and will be analyzed offline using proprietary software (called "algorithms") and artificial intelligence strategies. Detection of AF events using the investigational algorithms will be compared to the results from the standard monitoring to assess their reliability. Attention will be paid to recorded motion artifacts that can affect the quality and reliability of recorded signals. The ultimate aim is to establish that smart devices can potentially be used for monitoring purposes when used with specialized algorithms. Smart devices could offer an affordable alternative to standard-of-care cardiac monitoring.
Secretoneurin (SN) is a neuropeptide from the chromogranin family that influences intracellular calcium handling. SN suppresses calcium leakage from the sarcoplasmic reticulum through the ryanodine receptor. SN is a novel biomarker that has shown the potential to predict adverse arrhythmic events.
