LVAD-CF trial
Investigation of Predictive Factors for Hemodynamic Deterioration During Ventricular Arrhythmias in Patients with Left Ventricular Assist Devices
LVAD-CF trial
| Japan |
Severe heart failure with LVAD
| Cardiology |
Others
NO
To perform a quantitative assessment of circulatory dynamics during VA or right ventricular pacing simulating VA and to search for factors that correlate with the change in cardiac coefficient from baseline.
Others
Exploring Predictors
Percent change from baseline in cardiac index (CI) during VA or RV pacing
Deterioration in Circulation (CI Change -10, -20, -30%)
Right atrial pressure, pulmonary artery index, pulmonary vascular resistance, cardiac output, left ventricular ejection fraction, tricuspid annular systolic distance, Left ventricular end-diastolic diameter, left atrial diameter, and valvular disease severity, baseline BNP
Percent change from baseline in mixed venous oxygen saturation (SvO2) during VA or RV pacing
Percent change from baseline in mean arterial blood pressure (mAoP) during VA or RV pacing
Percent change from baseline in LVAD flow during VA or RV pacing
LVEDD, LAD, and valvular disease severity during ventricular arrhythmias or RV pacing
Interventional
Single arm
Non-randomized
Open -no one is blinded

Prevention
| Device,equipment |
In patients in whom sustained ventricular arrhythmia could not be induced during a standard electrophysiological study, pacing at 160 bpm and 200 bpm is performed for 5 minutes each.
| 18 | years-old | <= |
| Not applicable |
Male and Female
1.Patients who underwent left ventricular assist device (LVAD) implantation between January 1, 2015, and March 31, 2027, and are currently on LVAD support.
2.Patients meeting any of the following conditions and scheduled for hemodynamic evaluation via right heart catheterization:
1).Patients undergoing routine follow-up examinations (e.g., immediately post-LVAD implantation or in preparation for heart transplantation).
2).Patients experiencing frequent activation of the low-flow alarm.
3).Patients with uncontrollable systemic congestion (e.g., pleural effusion, lower extremity edema).
4).Patients with worsening valvular disease (defined as an increase in severity by at least one grade).
3.Patients with structural heart disease, left ventricular ejection fraction <40%, and documented ventricular arrhythmias.
4.Patients aged 18 years or older at the time of consent.
5.Patients who fully understand the study protocol and provide informed consent.
1.Patients with sustained ventricular arrhythmias.
2.Patients deemed unsuitable for the use of an EP catheter or a Swan-Ganz thermodilution catheter.
3.Patients judged by the investigator to be inappropriate as study subjects.
4.Patients who cannot provide informed consent.
