[Utility of omentoplasty for poststernotomy mediastinitis secondary to myocardial revascularization surgery]. / Utilidad de la omentoplastia en el tratamiento de la esternomediastinitis secundaria a cirugía de revascularización miocárdica.

Acute poststernotomy mediastinitis is a serious complication of cardiac surgery and is associated with high mortality. Conservative treatment with local debridement, irrigating-suction systems, and specific antibiotic therapy is sometimes inadequate. Omentoplasty is occasionally used for reconstruction and the treatment of various chest diseases. This useful procedure is most often indicated for suppurative processes and radionecrosis, to complement myoplasty, or to cover a chest wall prosthesis. When used to treat poststernotomy mediastinitis secondary to cardiac surgery, omentoplasty improves control of infection and prognosis. We describe 2 cases of poststernotomy mediastinitis secondary to cardiac revascularization surgery in which omentoplasty was an effective treatment. Excellent control of infection was achieved.

[Subaortic stenosis more than twenty years after surgical repair of a partial atrial septal defect in an adult]. / Estenosis subaórtica veinte años después de la reparación quirúrgica de un defecto septal auricular parcial en el adulto.

Subaortic stenosis after surgical correction of a partial atrioventricular septal defect is uncommon. When it occurs, it is usually diagnosed 6-8 years after early surgical repair in childhood. We present a female patient who underwent mitral valve cleft repair and closure of a partial atrial septal defect with a Teflon patch at the age of 48 years. Twenty-two years later, she presented with severe subaortic stenosis that required surgical repair. We analyze the intracardiac morphological factors associated with the development of late subaortic stenosis. We recommend long-term follow-up, even after surgical repair in adults.
