In the presence of high blood flow (Qa) AVF (&gt;\u20091.5 L\/min\/1.73\u2009m\n                      <jats:sup>2<\/jats:sup>\n                      ) and cardio-pulmonary recirculation (&gt;20%), high-output congestive heart failure (CHF) may occur and AVF flow reduction is recommended. Proximal Radial Artery Ligation (PRAL) is an effective technique for distal radio-cephalic (RC) AVF flow reduction.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>we evaluated six HD and four transplant patients with high-flow RC AVF and symptoms of CHF who underwent PRAL. We compared echocardiographic (ECHO) findings before (T0) and 1 and 6\u2009months (T1,T6) after PRAL. Preoperative ECHO was performed before (T0b) and after AVF anastomosis manual compression (T0c).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>At T1 AVF flow reduction rate was 58.4%\u2009\u00b1\u200913% and 80% of patients reported improved CHF symptoms. ECHO data showed an improvement of tricuspid annular plane systolic excursion (TAPSE) at T1 (p\u2009=\u20090.03) and a reduction of PAPS at T6 (p\u2009=\u20090.04). TAPSE improved after AVF anastomosis compression during preoperative ECHO (p\u2009=\u20090.03). Delta of TAPSE at the dynamic manoeuvre at T0 directly correlated with early (1\u2009month after PRAL, p\u2009=\u20090.01) and late (6\u2009months after PRAL, p\u2009=\u20090.04) deltas of TAPSE.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions:<\/jats:title>\n                    <jats:p>AVF flow reduction after PRAL induces immediate regression of CHF symptoms, early improvement of TAPSE and late improvement of PAPS, suggesting a prevalent right sections involvement in CHF.
