Brief Summary:
The Dual Chamber Atrial Tachyarrhythmias Adverse Events Study DATAS was designed to analyze the ability of dual chamber ICDs to reduce clinically significant adverse events as compared to single chamber ICD in a non selected population with conventional indication of ICD implantation
Detailed Description:
Single chamber SC implantable cardioverter defibrillators ICDs have several limitations that might be relevant during follow up like atrial pacing requirements inadequate therapies sustained atrial tachyarrhythmias and difficulties to achieve an accurate diagnosis of the arrhythmia Dual chamber DC ICDs offer an attractive rationale solution although controversy remains if the costs and complexity of the implants offer a real clinical advantage
The DATAS is a prospective multicentre randomized open labelled study with three arms two of them cross-over and the third parallels the other two
The primary objective of this trial is to determine whether use of Dual Chamber ICD DDED-DDDR NASPEBPEG DefibrillatorPacemaker Codes results in a significant decrease in the number of primary end points
The primary end point is a composite comprising four so-denominated Clinically Significant Adverse Events CSAE
1 all-cause mortality
2 invasive intervention hospitalization 24 h or prolongation of hospitalization due to cardiovascular cause
3 inappropriate shocks two or more episodes with inappropriate shocks
4 sustained symptomatic atrial tachyarrhythmias that a require urgent termination or b last more than 48 h leading to therapeutic intervention
Secondary objectives are
1 Number of each of the components of the CSAE
2 Arrhythmia related atrial tachyarrhythmia AT frequency and burden ventricular tachyarrhythmia frequency and burden number of appropriate shocks number of inappropriate shocks need for reprogramming need for medicationRadiofrequency Ablation RFA for arrhythmia control pacemaker syndrome and development of dual chamber pacing indication
3 Cardiovascular related New York Health Association NYHA functional class exercise capacity left ventricular ejection fraction LVEF reduction of medication diuretics
4 Quality of life evaluated by the SF-36 Minnesota living test with heart failure and Symptom Checklist instruments
