Introduction

The arteriovenous fistula (AVF) is the vascular access of choice for the treatment of chronic hemodialysis (HD). The relationship between fistula blood flow velocity and cardiac complications is controversial. Objective: Determine the correlation between the flow velocity (FV) of the arteriovenous fistula (AVF) with the tricuspid regurgitation velocity (TRV)

Methods

Correlation study. (Nov-July 21, 2022). Patients being treated with chronic HD ≥ 18 years of age, any gender. Patients with Left Ventricular Ejection Fraction (LVEF) < 45%, decompensated heart failure (HF) and pulmonary hypertension, active infection, Hemoglobin less than 8 gr/dl were excluded. The correlation was made between FV of the AVF (L/min) and TRV (m/ sec ).

Results

Forty-one patients were included. Twenty-four patients were male (58.5%). The average age was 48.8 years; Etiology of CKD was diabetic nephropathy in 46.3%, unknown cause in 39%, polycystic kidney disease in 9.8% of patients . The correlation between FV AVF and TRV Rho=-0.18 p=0.912. Other variables such as RA area Rho=0.602, RV thickness Rho=0.451 and urinary residual volume UVR Rho=-0.358, showed correlation p<0.05. The correlation between brachiocephalic (BC) and radiocephalic (RC) fistulas with TRV was not significant. The multiple regression analysis showed that the UVR predicts a decrease in the TRV of β =-0.01 (95% CI 0.01-0.02 ) p <0.0001, r 2 =0.39. RV thickness predicts an increase β =0.082 (95% CI 0.019-0.145) p<0.012, r 2 =0.48.

Conclusions

In the present investigation, no correlation was shown between FV AVF and TRV. According to the type of AVF, the TRV, therefore the PAP, as well as the CO, was higher in the BC AVF. Although the correlation in both groups was not different. However, UVR was found to be an important predictor for TVR. Which indicates a possible relationship between the patients volume status and the TVR, rather than the FV of the AVF.
