Introduction:

The anomalous origin of left coronary artery that originates in the pulmonary artery, known as Bland, White and Garland is a congenital heart disease, with low incidence, variable clinical spectrum and is not exclusive of the pediatric age group. It has a high mortality in the first year of life if not diagnosed and treated early.

Objective:

To describe the characteristics of the diagnosis of Bland, White and Garland syndrome.

Methods:

It was made the characterization of the entity in Cuba in a decade (2005 to 2015). There were included all the patients with clinical manifestations suggestive to Bland, White and Garland syndrome and echocardiographic confirmation. It was made the calculation of this entity´s prevalence and it was used the percentage in the qualitative variables and Fisher's exact test. The statistical validation of research results had a significance level lower than 5 %.

Results:

The estimated prevalence in that decade in Cuba was around 2.9 per 300 000 live births. It was demonstrated the variability in its clinical manifestations and wide range of onset´s age. The treatment is surgical with excellent survival and prognosis.

Conclusions:

The diagnosis of Bland, White and Garland syndrome is difficult through the clinical method due to the diversity in its presentation. The estimated prevalence in Cuba is greater than what was registered in the world today. Early diagnosis and prompt treatment significantly improves the survival and prognosis of patients suffering from this condition.
