          Abstract

          Resumen Introducción: El síndrome de Lutembacher corresponde a la asociación de un defecto interauricular (congénito o iatrogénico) e insuficiencia o estenosis mitral (congénita o adquirida). La etiología reumática es la causa más frecuente del compromiso mitral. Tiene una prevalencia reportada de 0.001 por cada 1.000.000 habitantes. Caso clínico: Paciente femenina de 6 años con cuadro de 10 meses de palpitaciones asociadas a dolor torácico. Se realizó un electrogardiograma en el que se evidenció bloqueo incompleto de la rama derecha del haz de His y prolongación del intervalo PR, además de un ecocardiograma en el que se visualizó una comunicación interauricular tipo ostium secundum no restrictiva de 28 mm, con cortocircuito de izquierda a derecha, dilatación del ventrículo derecho, prolapso de válvula mitral, valvas engrosadas e insuficiencia mitral moderada a grave. Se realizó plastia de válvula mitral y cierre quirúrgico de la comunicación interauricular, sin complicaciones. Durante el seguimiento se encuentra asintomática desde el punto de vista cardiovascular, en manejo farmacológico. Conclusiones: La asociación Lutembacher tiene una prevalencia de 0.001/1.000.000 habitantes; la mayoría tiene etiología reumática. La paciente no tiene historia de fiebre reumática y sería la paciente más joven reportada en la literatura con síndrome de Lutembacher.

          Abstract Introduction: Lutembacher’s syndrome corresponds to the association of an atrial septal defect (congenital or iatrogenic) and mitral regurgitation or stenosis (congenital or acquired), with rheumatic etiology being the most-frequent cause of mitral regurgitation. It has a reported prevalence of 0.001 for every 1,000,000 inhabitants. Clinical case: Female patient six years of age with a 10-month condition of palpitations associated with chest pain. An electrocardiogram was performed with evidence of incomplete right His bundle branch block and PR interval prolongation; additionally, an echocardiogram showed 28-mm non-restrictive ostium secundum atrial septal defect, with left-to-right shunt, right ventricular dilation, mitral valve prolapse, thickened valves, and moderate-to-severe mitral regurgitation. Mitral valve plasty and surgical closure of the atrial septal defect were performed, without complications. During follow-up, she was asymptomatic from the cardiovascular point of view, under pharmacological management. Conclusions: Lutembacher’s association has a prevalence of 0.001/1´000.000 inhabitants; the majority with rheumatic etiology. Our patient has no history of rheumatic fever and would be the youngest patient reported in the literature with Lutembacher’s syndrome.

          Lutembacher's syndrome

          The definition of Lutembacher's syndrome has undergone many changes. It refers to combination of congenital Atrial Septal Defect with acquired mitral stenosis. Lutembacher's syndrome is a very rare disease and in the past, it has been either overdiagnosed or misdiagnosed. Here, we will discuss a case of a pregnant lady who developed breathlessness during her third trimester of pregnancy and on detailed examination and investigation, she was found to be having Lutembacher's syndrome.

            Current diagnostic and treatment strategies for Lutembacher syndrome: the pivotal role of echocardiography.

            Lutembacher syndrome (LS) is a rare cardiac abnormality characterized by any combination of a congenital or iatrogenic atrial septal defect (ASD) and a congenital or acquired mitral stenosis (MS). Clinical features and hemodynamic effects of LS depend on the balance of effects of the MS and the ASD. Prognosis is influenced by several factors [pulmonary vascular resistance, right ventricle (RV) compliance, size of ASD and MS severity] but the occurrence of secondary pulmonary hypertension and congestive heart failure is commonly associated with poor outcome. Echocardiography remains the gold standard for diagnosis and evaluation of LS. Timely diagnosis is critical for modifying the natural course, by allowing patients to benefit from currently available percutaneous trans-catheter therapies with favorable effects on the outcomes. This article is a review of published literature on the current diagnostic and therapeutic modalities for LS, focusing on the pivotal role of echocardiography as the key diagnostic tool. Clinical suspicion of LS should prompt extensive investigation with non-invasive and where possible, invasive technics. Multicenter registers have a potential to assist the evaluation of long term outcomes of percutaneous trans-catheter therapies in patients with LS.

              Coexistent mitral valve disease with left-to-right shunt at the atrial level: clinical profile, hemodynamics, and surgical considerations in 67 consecutive patients.

              Between January, 1963, and June, 1985, 67 patients underwent corrective surgery for this complex anomaly. Symptoms and signs of atrial septal defect were dominant in the majority of subjects. History of rheumatic fever (46%), paroxysmal nocturnal dyspnea (33%), presence of an opening snap, mitral diastolic murmur, or pansystolic murmur provided clinical clues to document associated mitral valve disease. Open mitral valvotomy was accomplished in 39 subjects, while in the remainder (28 subjects) the valve required replacement. Partial anomalous venous connection was encountered in 12 subjects. Recognition and attention to the associated tricuspid incompetence is a high priority, and 21 subjects underwent concomitant annuloplasty. The overall hospital mortality was 13.4%, with no deaths in the last 22 consecutive patients. The period of follow-up ranged from 1 year to 22 years, with a mean +/- SD of 9.34 +/- 6.61 years. We believe, with other authors, that since the hemodynamic and therapeutic considerations are very similar, both the stenotic and regurgitant lesions should be included in the same syndrome.
