CAVA-ADHF is designed as a prospective, randomized, controlled, patient-blinded, multicenter, parallel-group trial. The objective is to test whether evaluation of the inferior vena cava diameter in addition to clinical assessment is superior compared to clinical assessment alone with respect to the surrogate endpoint of change in NT-proBNP from baseline to discharge. The CAVA-ADHF trial is supported by the Deutsches Zentrum für Herz-Kreislauf-Forschung (DZHK).
Only limited evidence is available on the best method to monitor and guide decongestion in acute decompensated heart failure. Therefore, no specific guideline recommendations are made in this regard. It is unknown whether an objective congestion marker can be used to guide decongestion or such marker is only of prognostic value by identifying high-risk patients with an advanced disease state.
CAVA-ADHF is designed as prospective, randomized, controlled, patient-blinded, multicenter, parallel-group trial and aims to demonstrate effectiveness of inferior vena cava (IVC)-guided decongestion, its feasibility, and to estimate effect size and variability of clinical endpoints following the intention-to-treat principle.
After inclusion and exclusion criteria have been checked patients will be randomized:
Experimental intervention: Decongesting treatment guided by clinical assessment and ultrasound evaluation of the IVC diameter. Decongestion should lead to a maximal IVC diameter ≤2.1 cm and IVC collapsibility index >50% in addition to relief of symptoms and signs of congestion before discharge.
Control intervention: Decongesting treatment guided by clinical assessment alone. The IVC ultrasound evaluation is performed, but results are not reported to treating physicians.
Trial intervention will end with discharge from the index hospitalization. Patients will be followed-up for 180 to 210 days after randomization.
The CAVA-ADHF trial is supported by the Deutsches Zentrum für Herz-Kreislauf-Forschung (DZHK).

| Change in NT-proBNP from baseline to discharge | The core laboratory at Luebeck will determine NT-proBNP levels for calculation of the endpoint from samples obtained at baseline and at discharge. | Measured at baseline (within 24 hours of admission to index hospitalization) and on the day of discharge from index hospitalization (discharge planning is at the discretion of treating physician but will be around 5 to 8 days after admission) |
| Measure | Description | Time Frame |
|---|---|---|
| Proportion of patients with IVC ultrasound on two thirds of days in hospital and at discharge among all randomized patients | Proportion of patients with per-protocol treatment in the experimental group. | Measured on the day of discharge from index hospitalization (discharge planning is at the discretion of treating physician but will be around 5 to 8 days after admission) |

| Sham ultrasound evaluation of the inferior vena cava diameter | Diagnostic Test | Teatment guided by clinical assessment alone. Decongestion should lead to relief of symptoms and signs of congestion before discharge. IVC ultrasound evaluation is performed, but results are not reported to treating physicians. |

| All-cause mortality | Participants will be contacted by telephone at 180 days (180 to 210 days) after randomization to assess vital status (all-cause mortality). In case of unavailability patients, relatives, general practitioners, and/or population register will be contacted. | 180 days after randomization |
| Cardiovascular mortality | Participants will be contacted by telephone at 180 days (180 to 210 days) after randomization to assess vital status (all-cause mortality). In case of unavailability patients, relatives, general practitioners, and/or population register will be contacted. Medical reports will be requested to adjudicate cause of death. | 180 days after randomization |
| Unscheduled readmission for any cause | Participants will be contacted by telephone at 180 days (180 to 210 days) after randomization to assess readmission status. In case of unavailability patients, relatives, general practitioners, and/or population register will be contacted. | 180 days after randomization |
