Ist eine ICD-Programmierung auf eine Schockenergie der doppelten intraoperativen Defibrillationsschwelle im Langzeitverlauf sicher effektiv? Ergebnis…

1999

Ziel dieser kontrollierten, prospektiven, randomisierten Studie war die Untersuchung der Effektivitat und der Sicherheit einer reduzierten Defibrillationsenergie mit biphasischer Schockform und einem endokardialem ICD-Sondensystem. 176 Patienten, die klinisch ein typisches ICD-Patientenkollektiv darstellten, wurden im Rahmen der Studie untersucht. Alle Patienten erhielten ein ICD-Aggregat mit der Moglichkeit der Episodenspeicherung (Ventak TM PRx II, PRx III) in Verbindung mit einem rein endokardialem Sondensystem (Endotak TM Serie 0070; 0090, CPI). Die intraoperative Defibrillationsschwelle (DFT) sollte ≤15 J betragen. Die DFT wurde in einem Protokoll mit absteigenden Energiemengen (15, 10…

Safety and efficacy of implantable defibrillator therapy with programmed shock energy at twice the augmented step-down defibrillation threshold: resu…

1999

Whether the safety and efficacy of implantable cardioverter defibrillator (ICD) therapy can be assured with lower output devices is an important question. The purpose of this study was to evaluate whether programming the device output at twice the augmented defibrillation threshold was as safe and effective as using the maximum energy. Patients indicated for ICD therapy, but without slow monomorphic ventricular tachycardia (MVT), who achieved an augmented defibrillation threshold (DFT plus)or = 15 joules (J) with a single endocardial lead system and a biphasic defibrillator were included in the study. Prior to ICD implantation, patients were randomized into 2 groups. The shock energies in t…

Gold vs. platinum-iridium tip catheter for cavotricuspid isthmus ablation: the AURUM 8 study

2010

Aims Gold electrodes have the theoretical advantage of creating bigger lesions than platinum–iridium (Pt–Ir) electrodes. We performed a prospective randomized study to compare the clinical efficacy of standard 8 mm Pt–Ir tip catheter (control) and 8 mm gold-tip catheters in the ablation of the cavotricuspid isthmus (CTI)-dependent atrial flutter. Methods and results A total of 463 patients undergoing CTI ablation in 19 clinical centres were randomized to receive the treatment by gold-tip or control catheter. The primary endpoint was cumulative radiofrequency (RF) application duration until achieving bidirectional CTI block. It did not differ significantly for the two catheters. The gold-tip…

Reproduzierbarkeit der Defibrillationseffektivität zur Terminierung von induziertem Kammerflimmern unter Verwendung der intraoperativ gemessenen Defi…

1998

Ziel vorliegender Untersuchung war es, die Reproduzierbarkeit der Effektivitat der nach einem modifizierten Protokoll intraoperativ bestimmten Defibrillationsschwellenenergie im Langzeitverlauf zu uberprufen. Hierzu wurden im Rahmen einer Substudie einer prospektiven, randomisierten Multizenterstudie (“Low Energy Endotak Trial” LEET)) zwischen Dezember 1993 und Januar 1996 83 Patienten, die im Rahmen einer Erstversorgung mit einem implantierbaren Kardioverter-Defibrillator (ICD) in Kombination mit einem transvenosen Einzelelektrodensystem eine intraoperativ bestimmte Defibrillationsschwelle (DFT) ≤15 J aufwiesen, eingeschlossen. Zur Bestimmung der DFT wurde ein Protokoll mit absteigenden En…

[Is ICD-programming for double intraoperative defibrillation threshold energy safe and effective during long-time follow-up? Results of a prospective…

1999

The aim of this prospective and randomized study was to evaluate the safety and efficacy of a reduced shock strength in transvenous implantable defibrillator therapy. So far clinical data concerning the safety margin of the shock energy in ICD therapy do not exist. The shock energy tested during long-term follow-up in this study was twice the intraoperatively measured defibrillation threshold (DFT). A total number of 176 consecutive patients representing a typical cohort of ICD patients were evaluated. All patients received a non-thoracotomy lead system (CPI, Endotak 0070, 0090) and a biphasic cardioverter-defibrillator with the ability to store episodes (Cardiac Pacemakers Inc., Ventac TM …
