Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery Associated with Right Coronary Giant Aneurysm.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital malformation, usually diagnosed in the infant period due to myocardial ischemia and heart failure, with the need for emergency surgery. Less commonly, it can be asymptomatic until adulthood. Coronary artery aneurysms are also rare anatomical anomalies with symptoms of acute or chronic angina or even remain completely asymptomatic. We present an unusual case of ALCAPA, associated with a giant aneurysm of the right coronary artery.

Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) in adults: Collateral circulation does not preclude direct reimplantation.

BACKGROUND: The adult type of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is characterized by late presentation due to collateral coronary flow. Patients often present with long time recurrent angina or dyspnea. Surgical correction can be a challenge due to the vast collateral coronary circulation. CASE PRESENTATION: A previously healthy 41-year-old male presented in the emergency room referring typical angina and dyspnea. Coronary angiography revealed ALCAPA. Surgical correction was indicated. Under cardiopulmonary bypass, the left main coronary artery ostium was isolated and directly reimplanted in the aorta. The patient was discharged from the hospital without complications and asymptomatic. Control coronary angiography showed enlarged left main coronary artery and regression of the collateral circulation. CONCLUSION: Even with a well-developed collateral circulation, detachment of the left coronary artery and direct implantation in the aorta is feasible, achieving good long-term results.

Síndrome de ALCAPA em uma Mulher Jovem / ALCAPA Syndrome in a Young Woman

Mulher de 18 anos com histórico de síncope, angina e palpitações há um ano. Uma indicação crucial era artéria coronária direita dilatada na ecocardiografia transtorácica. Os achados da tomografia computadorizada resultaram no diagnóstico da origem anômala da artéria coronariana esquerda proveniente da síndrome da artéria pulmonar.(AU)

Origen anómalo de la arteria coronaria izquierda a partir de la arteria pulmonar / Anomalous origin of left coronary artery from the pulmonary artery

Introducción: El origen anómalo de la arteria coronaria izquierda que nace en la arteria pulmonar, conocido como síndrome de Bland, White y Garland, es una enfermedad cardiaca congénita, de baja incidencia, espectro clínico variable y no es exclusiva de la edad pediátrica. Tiene una alta mortalidad en el primer año de vida si no se diagnostica y trata oportunamente. Objetivo: Describir las características del diagnóstico del síndrome de Bland, White y Garland. Métodos: Se realizó la caracterización de la entidad en Cuba en un decenio (2005 a 2015). Se incluyeron todos los pacientes con manifestaciones clínicas sugerentes de síndrome de Bland, White y Garland y confirmación ecocardiográfica. Se realizó el cálculo de la prevalencia de la entidad y se empleó el porcentaje en las variables cualitativas y la prueba exacta de Fisher. La validación estadística de los resultados de la investigación adoptó nivel de significación menor a 5 por ciento. Resultados: La prevalencia estimada en esa década en Cuba estaba alrededor de 2,9 por 300 000 nacidos vivos. Se demuestra la variabilidad en sus manifestaciones clínicas y amplio rango de edad de presentación. El tratamiento es quirúrgico con excelente supervivencia y pronóstico. Conclusiones: El diagnóstico del síndrome de Bland, White y Garland es difícil mediante el método clínico debido a la diversidad en su presentación. La prevalencia estimada en Cuba es mayor que lo registrado en el mundo actual. El diagnóstico temprano y tratamiento oportuno mejora de forma significativa la supervivencia y el pronóstico de los pacientes aquejados por esta dolencia(AU)

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 percent. 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(AU)

Evaluation of Anomalous Coronary Arteries from the Pulmonary Artery.

Objective: This study evaluated clinical and diagnostic findings, treatment methods, and follow-up of cases of anomalous coronary arteries from the pulmonary artery. Methods: The study included all cases diagnosed with anomalous coronary arteries from the pulmonary artery between January 2012 and January 2016. Data from patients' demographic characteristics, electrocardiography, echocardiography, angiographic findings, operation, intensive care unit stay, and follow-up were evaluated. Results: The study included 12 patients (8 male, 4 female), 10 with anomalous left coronary artery from the pulmonary artery (ALCAPA) and 2 with anomalous right coronary artery from the pulmonary artery (ARCAPA). Median age at diagnosis was 4 months (range, 1 month - 10 years old) and median weight was 5.5 kg (range, 3-30 kg). The most common complaints were murmur (n=7) and respiratory distress (n=5). In 4 cases, the initial diagnosis was dilated cardiomyopathy. Electrocardiographs were pathologic in all cases. Echocardiographic examination revealed medium to severe mitral valve regurgitation in 4 cases and reduced (< 40%) ejection fraction in 6 patients. Of the 12 patients, 8 underwent direct implantation of the left coronary artery into the aorta, 2 underwent implantation of the right coronary artery into the aorta, and the remaining 2 underwent a Takeuchi procedure. There were no early mortalities. Median hospital stay was 20 days (range, 5-35 days). Median follow-up duration was 18 months (range, 5-36 months), and no cases required further surgery during follow-up. Conclusions: Anomalous coronary arteries from the pulmonary artery can be successfully repaired providing there is early diagnosis and effective, appropriate intensive care unit follow-up. Therefore, coronary artery origins should be evaluated carefully, especially in cases with dilated cardiomyopathies.
