Radiofrequency Ablation of Paroxysmal Supraventricular Tachycardia Using a Novel Catheter Equipped...

Paroxysmal Supraventricular Tachycardia

Paroxysmal supraventricular tachycardia is treated with radiofrequency ablation recently. This procedure is performed by ablating slow pathway or accessory pathway using radiofrequency ablation catheter. Recently developed mirofidelity (MIFI) catheter has mini-electrodes that can record local eletrogram with higher resolution. We aimed to investigate the efficacy of MIFI catheter in the ablation of paroxysmal supraventricular tachycardia compared to conventional radiofrequency ablation catheter. Enrolled patients undergo conventional electrophysiologic study. Patients with sustained supraventricular tachycardia during the study are randomized to either study group or control group. Radiofrequency ablation is performed using MIFI catheter in the study group, and conventional catheter (Blazer II) in the control group. The study endpoints are recorded immediately after ablation and there is no additional follow up or management after procedure.

TOCCATA - Touch+™ for Catheter Ablation

Atrial FibrillationTachycardia1 more

The main objective of this study is to demonstrate the clinical safety of a contact force sensing RF ablation catheter when used for the treatment of supraventricular tachycardia and atrial fibrillation. In addition, the study will characterize the use and value of contact force measurement during ablation, and the long term success (12 months) of the ablation procedure using this technology.

Oral Verapamil in Acute Paroxysmal Supra Ventricular Tachycardia(PSVT) Recurrence Control

Paroxysmal Supraventricular Tachycardia

PSVT is a common rhythm disorder in emergency department which can be recurrent in some cases. Intravenous Adenosine is the drug of choice in PSVT control in acute settings but is a very short acting agent. Providing a complementary medication to decrease the rate of recurrence of PSVT after its initial control will be promising. This study evaluates the role of the oral Verapamil in recurrence control of PSVT in emergency situations.

Reducing Episodes by Septal Pacing Efficacy Confirmation Trial (RESPECT)

Atrial FibrillationTachycardia3 more

The purpose of this study is to find out if specialized programs in the AT500 and EnRhythm pacemakers will reduce the number of irregular heartbeat in the upper chamber of the heart and reduce symptoms (such as shortness of breath, dizziness, and others).

Simulation of Adenosine Push Methods for Treatment of SVT Using Agitated Saline Visualized by Ultrasound...

Supraventricular Tachycardia

Supraventricular tachycardia (SVT) is an abnormally fast heart rhythm arising from improper electrical activity in the upper part of the heart. SVT is commonly treated with adenosine using three different IV administration techniques. However, it is not well known which of these three techniques is the quickest or most likely to reach the heart in order to stop SVT. This study will simulate each of those techniques in an investigator-blinded procedure. Intravenous agitated saline, used as a surrogate for a dose of adenosine, will be administered to healthy volunteers using all three techniques and monitored using bedside ultrasound to observe their efficacy and speed in reaching the right side of the heart.
