Review Comparative Study
Mechanical circulatory support for infants and children with cardiac disease.
Mechanical circulatory support is assuming an expanding role in the practice of congenital cardiac surgery. Extracorporeal membrane oxygenation and centrifugal ventricular assist devices are still the mainstay of mechanical circulatory support for children; however, newly developed pulsatile, paracorporeal ventricular assist devices designed for pediatric applications are achieving increased utilization. In addition, several new, continuous flow devices that are under development as fully implantable systems for adults, ultimately may be useful for pediatric patients.

Fistulous communication between the aorta and the pulmonary parenchyma developed in a 38-year-old woman 19 years after repair of a congenital aortic coarctation with Dacron patch aortoplasty. The fistula, inducing intermittent hemoptysis, arose from the suture line between the prosthetic fabric and the aorta. There was no infectious background or aneurysm at the primary repair site. The aortic segment including the prosthetic patch was resected and replaced with a Dacron tubular vascular prosthesis.

Initiating outpatient therapy with ventricular assist devices (VAD) was important in the progress of mechanical circulatory support. This article reviews our experience with VAD therapy from the start of our outpatient program until the present. ⋯ Ventricular assist devices effectively support outpatients for months to years. The anticipated time for postoperative recovery and VAD training before discharge is approximately 14 to 21 days, although shorter times may be possible in the future. Establishing a successful outpatient VAD program is a crucial step toward VAD as definitive therapy for end-stage heart disease.

The management of non-small cell carcinomas of the lung involving the superior sulcus remains controversial. The goal of this retrospective study was to evaluate the role of surgery, radiotherapy, and chemotherapy for the treatment of superior sulcus tumors, to define the best surgical approach for radical resection, and to identify factors influencing long-term survival. ⋯ The optimal treatment for superior sulcus tumors is complete surgical resection. The surgical approach (anterior/posterior) did not influence the 5-year survival rate. Preoperative radiotherapy should be recommended to improve outcome of patients with a superior sulcus tumor.

Long-term results of aortic valve regurgitation after repair of ruptured sinus of valsalva aneurysm.
We reviewed our 35-year-experience to investigate the determinants of long-term results of aortic valve regurgitation (AR) after surgical repair of ruptured sinus of Valsalva aneurysms (RSVA). ⋯ Late AR necessitating reoperation still confers significant risk in the long-term follow-up after repair of RSVA. No particular risk factor of preoperative conditions and surgical methods was elucidated in this study, and postoperative AR at discharge from the hospital was the only factor determining the long-term results of AR.
