“…(a) Thickening of the free ridge of the valve cusps (Fig. 5 ) has been described in some specimens (Formanek et al, 1971) and may be diagnosed on angiography ( 6 cases in our series, one of which was confirmed at operation). It is probably not a serious complication and when there is valvular stenosis the gradient is usually small, but we cannot yet be certain that it will remain harmless with the passage of time.…”

Banding of the pulmonary artery has been shown to be a useful procedure in infants with a large ventricular septa1 defect, enabling them to survive until a suitable age for repair of the defect.According to the classification used, a type I1 VSD has a large left to right shunt with a loud, low-pitched systolic murmur, associated with pulmonary hypertension and left ventricular hypertrophy; in type I1 (a) the pressure in the pulmonary artery does not exceed 70% of the systemic pressure and pulmonary resistance is normal; in type I1 (b) the pressure in the pulmonary artery is more than 70% of the systemic pressure, and there is moderate increase in pulmonary resistance.Catheterization, including angiocardiography, has been performed in 27 infants aged from 32 months to 8 years, who had previously undergone banding of the pulmonary artery.

“…When placed, the band may be positioned just above the leaflets of the pulmonary valves, and turbulent flow through the band can then promote vascular injury and thickening. 97 The alteration in form and function of the pulmonary valve subsequent to banding may also confound the arterial switch procedure, or the integrity of an anastomosis of the Damus-Kaye-Stansel type, neither of these procedures having been anticipated during these early experiences. [98][99][100][101][102][103][104][105] Contemporary results with banding are much improved, considering the dramatic change in the population treated.…”

Designing therapeutic strategies for patients with a dominant left ventricle, discordant ventriculo-arterial connections, and unobstructed flow of blood to the lungs

et al. 2004

The palliation of the cyanotic child with a dominant morphologically left ventricle, discordant ventriculo-arterial connections, and obstruction to the pulmonary outflow tract has continued to evolve and mature. The evolution began in the early days of surgical palliation with the Blalock-Taussig shunt, extended to construction of cavopulmonary shunts, if required, and then to the Fontan procedure and its subsequent modifications. This journey took nearly 30 years to complete. There is increasing clinical data to document the beneficial effects of this approach, with ever-improving outcomes. Some aspects of the history of the cavopulmonary shunt have been previously reviewed in this journal and elsewhere, as have analysis of outcomes for some groups of patients considered for surgical completion of the Fontan circulation. While there has been some ongoing interest in ventricular septation since the early success of Sakakibara et al., this approach has largely been abandoned. Considerably more challenges and debate resonate in the surgical algorithms defined for patients whose hearts are characterized by a dominant left ventricle, discordant ventriculo-arterial connections, and unobstructed flow of blood to the lungs. This latter group will be the focus of this review, as will the aetiology of the myocardial hypertrophy that is particularly frequent in this group of patients, its clinical recognition, indeed its anticipation, and the multiple surgical strategies designed to prevent or treat it. All these manoeuvres are considered to optimise suitability for, and outcome from, creation of the Fontan circulation.
