Comparative Study
Anterolateral minithoracotomies for the radical correction of congenital heart diseases.
During the past 10 years, minimally invasive surgical techniques have been applied more and more widely in both adult and pediatric populations, especially in female patients. Right anterolateral minithoracotomy is an alternative to median sternotomy that yields a better cosmetic outcome. From May 1997 through September 2008, 132 patients (107 females, 25 males) underwent open-heart surgery through right anterolateral minithoracotomy. ⋯ All patients had gratifying cosmetic results at longer follow-up. Indeed the mortality and morbidity rates obtained through our approach were almost the same as those obtained through median sternotomy, and there were no significant differences in cardiopulmonary bypass time, aortic cross-clamp time, ventilation time, or postoperative hospital stay. We conclude that the right anterolateral minithoracotomy for correction of congenital heart defects offers superior cosmetic results without increasing morbidity or mortality rates and confers upon patients psychological and social satisfaction.

We sought to evaluate retrospectively the outcomes of patients at our hospital who had moderate ischemic mitral regurgitation and who underwent coronary artery bypass grafting (CABG) alone or with concomitant mitral valve repair (CABG+MVr). A total of 83 patients had a reduced left ventricular ejection fraction and moderate mitral regurgitation: 28 patients underwent CABG+MVr, and 55 underwent CABG alone. Changes in mitral regurgitation, functional class, and left ventricular ejection fraction were compared in both groups. ⋯ In patients with moderate ischemic mitral regurgitation, either surgical approach led to an improvement in functional class. Early and intermediate-term mortality rates were low with either CABG or CABG+MVr. However, an increased rate of late recurrent mitral regurgitation in the CABG+MVr group was observed.

There are few published reports of the results of supravalvular aortic stenosis correction with the use of Brom's 3-patch technique. Herein, we report our use of this procedure and the short-term results therefrom. From 2002 through 2007, 9 children underwent surgical correction of localized supravalvular aortic stenosis at our hospital. ⋯ In all 8 patients who survived, postoperative transaortic blood pressure gradients were improved (range, 0-16 mmHg), and no repeat operations were needed after 6 to 55 months' follow-up. We consider Brom's technique to be safe in the repair of supravalvular aortic stenosis. In our limited series, it produced effective anatomic restoration, with good short-term and potentially good long-term results.

Pulmonary arteriovenous fistulae are known to develop in patients who have functional single-ventricle heart disease and interruption of the inferior vena cava with direct hepatic drainage to the heart, in which a bidirectional Glenn shunt is the only source of pulmonary blood flow. The progressive systemic arterial hypoxemia that is associated with pulmonary arteriovenous fistulae can have important clinical consequences. Baffling the hepatic venous return to the pulmonary circulation can alleviate pulmonary arteriovenous fistulae. ⋯ Revision of the conduit improved mixing of hepatic venous effluent with blood flow from the bidirectional Glenn shunt. Three years after this revision, the patient's oxygen saturation remained stable at 90%, and his physical activity was markedly improved. We present our rationale for selected redirection of the conduit and discuss other surgical options that can improve hypoxemia that is associated with pulmonary arteriovenous fistulae.

Diagnostic evaluation of embolic neurologic events requires the consideration of cardiac causes. We recently encountered a case that emphasizes the importance of cardiac tumor as a source of embolic events. We present herein the case of a 42-year-old woman who suffered a transient ischemic attack caused by a papillary fibroelastoma that originated from the aortic valve.
