The diagnosis is likely coarctation of the aorta. This condition is characterized by narrowing of the aorta, leading to decreased blood flow to the lower extremities. The murmur on the left upper sternal border is a common finding in coarctation of the aorta, as is an enlarged liver. The absence of femoral pulses and peripheral cyanosis in the lower extremities further support this diagnosis.
