The surgical treatment of tetralogy of Fallot has passed through various phases. Initially, Blalock and Taussig1 devised the subclavian pulmonary artery shunt which was followed by the Potts modification.2 Thousands of these operations have been performed to the benefit of many patients.
Despite the rapid development of instruments and techniques for open heart surgery, the best initial surgical treatment of an infant severely troubled by a tetralogy of Fallot is still the establishment of a systemic pulmonary arterial shunt. With few exceptions most surgeons now favor the Blalock procedure (subclavian pulmonic anastomosis) because of the ease with which it can be taken down later when complete correction of the cardiac anomaly is undertaken. The problem confronting cardiac surgeons today is the management of patients with established Potts anastomoses who are now ready for total correction of their tetralogy.
