We report on the impact of establishing LSVC to right superior vena cava (RSVC) continuity on the growth of borderline hypoplastic left ventricular structures as an addendum to our previously published work.<\/jats:p><jats:p>Twenty-two patients underwent LSVC to RSVC anastomosis, whereas six had LSVC ligation (n\u2009=\u20094) or clip closure (n\u2009=\u20092), all alongside congenital heart defect correction. The indication was LSVC-related obstruction of left ventricular inflow due to a dilated coronary sinus. Clinical data were systematically reviewed, with regular follow-up. Left ventricular end diastolic diameters (LVEDD), aortic valve diameters, and left ventricular outflow tract (LVOT) diameters were recorded using echocardiography.<\/jats:p><jats:p>Follow-up showed 90% survival at 3.3\u2009\u00b1\u20090.4 years.
