Filter by:The goal of this study is to compare OTW balloon with microcatheter in the Marshall vein alcohol ablation study. The main questions it aims to answer are: • Is there a difference in the effectiveness and safety of OTW balloon and microcatheter in Marshall vein alcohol ablation? Participants will be asked to: Undergo treatment with OTW balloon Undergo treatment with microcatheter If there is a comparison group: Researchers will compare the OTW balloon group and the microcatheter group to see different effects.
A randomized controlled trial will be conducted to evaluate the efficacy of Ablation Index-guided high power - short duration (HPSD) ablation compared to conventional power settings in Cavotricuspid Isthmus (CTI) dependent atrial flutter. Participants will be randomized to receive either AI-guided HPSD ablation at 50 Watts or conventional power settings at 30 Watts. Both arms will use the Carto 3D mapping system and the QDOT MICRO ablation catheter (Biosense Webster). An anatomically contiguous line will be created with <6mm inter-lesion distance. After a standardized wait time of 30 minutes, ablation success will be assessed. The primary outcome is total radiofrequency ablation time. Secondary outcomes include procedural time, fluoroscopy time, safety outcomes, and 3-month freedom from recurrence. It is our expectation that HPSD will result in a shorter primary outcome.
This is an exploratory research aiming to accurately identify the site of origin of tachyarrhythmia using Magnetocardiography (MCG), which will have guiding significance for early diagnosis, the formulation of treatment plans and preoperative positioning for radiofrequency ablation.
INTRODUCTION: The study focuses on comparing the effectiveness of oral Bisoprolol, a beta-1 adrenergic receptor blocker, against intravenous Diltiazem, a calcium channel blocker, in treating rapid atrial fibrillation or flutter with rapid ventricular response in an emergency setting. This research aims to fill the gap in empirical evidence regarding the use of oral Bisoprolol for these conditions, potentially offering a convenient, evidence-based alternative for patient management in emergency departments where established protocols are lacking. METHOD: This study is a randomized controlled trial targeting patients who present to the emergency room with symptomatic atrial fibrillation or flutter and rapid ventricular response requiring intervention. Participants will be split into two groups and undergo continuous monitoring of vital signs and regular electrocardiograms to ensure safety and document any adverse effects. The primary focus is on patient safety while evaluating the efficacy of the treatments. AIM: Evaluate the efficacy and safety of oral bisoprolol in treating atrial fibrillation or atrial flutter with rapid ventricular response in an emergency department setting. PRIMARY OJECTIVES: The primary efficacy outcome will be evaluated by achieving a HR<110 beats per minute or a decrease ≥20% of baseline HR at 60 minutes. The primary safety outcome measures are HR < 60 bpm and SBP < 95 mm Hg. SECONDARY OBJECTIVES: The use of Rescue medication, proportion of patients who required hospitalization, worsening of heart failure or pulmonary oedema, side effect of medication ( dizziness, headaches, gastrointestinal symptoms) PATEINT POPULATION: Adults (18 and older) presenting to the emergency department at Sultan Qaboos University Hospital with symptomatic atrial fibrillation or atrial flutter with rapid ventricular response requiring treatment. INTERVENTION: A single oral dose of 5 mg Bisoprolol (maximum dose of 5 mg) or a single intravenous dose of Diltiazem at 0.25 mg/kg (to a maximum dose of 30 mg). CLINICAL MEASURMENT: Heart rate recorded every 15 minutes up to the 90-minute mark, with a 12-lead ECG performed every 30 minutes. OUTCOME: For therapy to be considered effective, patients must achieve a ventricular rate ≤110/min or experience a drop-in ventricular rate of at least 20% at 60 minutes.
This is a prospective, single-group clinical study. The objective is to evaluate the safety and efficacy of focal pulse ablation system in the treatment of typical atrial flutter.
The study is a prospective single-arm multicenter clinical trial. Adult patients will be consented and enrolled in an outpatient cardiology office or Arrhythmia Clinics.
The overall goal of this study is to evaluate the effectiveness of a previously developed storytelling intervention on anticoagulation (AC) initiation/persistence in African American and Black patients with atrial fibrillation/flutter. The investigators hope to gain knowledge that may help treat atrial fibrillation or flutter and lower stroke and adverse cardiovascular event risks for African American and Black patients by increasing the use of blood thinning medications known as anticoagulants.
Intracardiac echocardiography (ICE), has been an essential component of Radiofrequency (RF) ablations for AF given its association with decreased fluoroscopy time and complication rates, and therefore it is logical that this can be applied to CTI ablations for AFL as well. There are however no studies to date that directly focused on the benefits of adding ICE during CTI dependent AFL ablation. Currently it is not required that operators use ICE in every case of AFL ablation. Investigators intended to study the routine use of ICE in such cases and to see if there is a significant benefit in routine use of ICE.
All calls that end up on the out-of-hours general practitioners' service (OHGPS), which contain a demand for an urgent home visit, are passed on to the on-call general practitioner (GP). These calls are randomized into two arms: after the patient's informed consent, they are assigned either to one arm where the monitoring device, PICO, is applied together with the GP's general care or to the other arm where only the usual care is provided. All data such as suspected diagnosis, treatment or referral, influence of the parameters, ECG and/or alarms on the management and the user-friendliness are recorded. After 30 days, the diagnosis and evolution is requested from the patient's own GP or, if referred to a hospital, in the hospital in order to be able to compare the effect of the approach by the GP between both arms. The aim is to investigate if 1/ the use of the PICO monitoring device could improve GPs' decisions to refer to hospital or not in urgent cases; 2/ there is a difference between the diagnosis with and without the use of the monitoring device using the final diagnosis by the electronic health record of the own GP of the patient; 3/ the call to send a GP for an emergency contained sufficient information for the OHGPS phone operator to take an appropriate decision; 4/ the build-in alarms help the GP during his intervention; 5/ the PICO is easy to use during an emergency; 6/ the use of the device makes them feel more confident in transmitting the information to the Medical Emergency Team.
