RESUMEN
A case of anomalous origin of the left coronary artery from the pulmonary artery in a patient with the origin of the coronary opposite to the aorta is reported. Between many surgical options we conclude to reestablish a double coronary system reconnecting the coronary through a conduit created with a pulmonary wall baffle and an autologous pericardial patch.
RESUMEN
OBJECTIVE: Mitral valve prolapse is a rare condition and represents a challenge for cardiac surgeons. Many techniques have been described to treat the wide spectrum of abnormalities causing mitral valve regurgitation but the low incidence of these abnormalities is the cause of the relatively poor experience of many institutions. METHODS: From April 2005 to September 2006, five patients underwent isolated mitral valve repair with the edge-to-edge technique for anterior or bileaflet prolapse. Three patients also had a Gore-Tex strip to reinforce the posterior annulus, whereas two had a 26-size soft incomplete ring annuloplasty. RESULTS: There was no death and none of the patients required reoperation. None of the patients had mitral regurgitation more than 1+ at a mean follow-up of 30 months. None of the patients had mitral stenosis or any valve-related event. CONCLUSION: The edge-to-edge technique is a well tolerated and useful technique for the anterior or bileaflet prolapse of the mitral valve. Although many techniques have been described with good results, in many anatomical settings and in small patients, edge-to-edge is a good option and might not interfere with the growth of the valve. Early results are encouraging but a longer follow-up is needed to evaluate the long-term prognosis.

Serum concentrations of brain natriuretic peptide and its amino-terminal cleavage pro-fragment, NT-proBNP, have never been reported in refractory Kawasaki disease. Changes in NT-proBNP levels after infliximab treatment in an infant with severe cardiovascular complications are reported here. The regular evaluation of this cardiac biomarker after infliximab treatment may have clinical relevance in patients with refractory Kawasaki disease and severe heart involvement.

The dimensions of the entire aorta at different anatomic levels were measured by transthoracic 2-dimensional echocardiography in 162 consecutive patients with isolated bicuspid aortic valves (BAVs) without significant aortic valve dysfunction. Aortic dilation involved the aortic root and the ascending aorta but was not present in the descending and abdominal aorta. A significant increase in the dimensions of the aortic arch was found in patients with BAVs aged >40 years. Ascending aortic diameter and the extension of aortic dilation were significantly correlated with age, but no correlation was found between aortic dimensions and aortic valve morphology.
