The Annals of thoracic surgery

The incidence of rheumatic heart disease (RHD) has increased recently in the western United States. We reviewed our 18-year surgical experience with RHD in children to examine current surgical techniques and results. ⋯ Children with RHD in the United States uncommonly require valve operation. Mitral repair with a technique that allows annular growth is possible in most children with good long-term functional results. Long-term surveillance of children with RHD is necessary because of the possible need for late valve operation.

Randomized Controlled Trial Comparative Study Clinical Trial
Papaverine delivery to the internal mammary artery pedicle effectively treats spasm.
Left internal mammary artery spasm is well recognized during coronary artery bypass operations. Papaverine has been used by many surgeons to maximize mammary artery flow perioperatively, but the best delivery method is not known. We analyzed two techniques used at our institution. ⋯ Papaverine delivery to the left internal mammary artery after dissection treats spasm effectively, improves blood flow at the time of its anastamosis to the left anterior descending artery, and avoids any risk of intimal injury. Injection of papaverine before mammary artery harvest does not shorten dissection time, and flow is not statistically improved.

We are analyzing our experience with treatment of desmoid tumors of the chest wall and adjacent structures. ⋯ Desmoid tumors involving the chest and adjacent structures are locally aggressive tumors with a high recurrence rate. Wide radical resection should be attempted whenever possible. Positive margins at resection, reoperation and postoperative radiation are associated with a high risk of local recurrence.

We assessed the clinical outcome and conducted an angiographic study of total arterial off-pump coronary artery bypass grafting for revascularization of the total coronary system. ⋯ Total arterial off-pump coronary artery bypass yielded good clinical results and an excellent patency rate of revascularization for the total coronary system.

Pulmonary resection after chemotherapy and concurrent full-dose radiotherapy (>59 Gy) has previously been associated with unacceptably high morbidity and mortality. Subsequently neoadjuvant therapy protocols have used reduced and potentially suboptimal radiotherapy doses of 45 Gy. We report a series of 40 patients with locally advanced non-small-cell lung cancer who successfully underwent pulmonary resection after receiving greater than 59 Gy radiation and concurrent chemotherapy. Operative results and midterm survival follow-up are presented. ⋯ Pulmonary resection may be performed safely after curative intent concurrent chemotherapy and radiotherapy to greater than 59 Gy. High pathologic complete response rates and sterilization of mediastinal lymph nodes were observed accompanied by highly favorable survival rates. This experience, though promising, will require confirmation in a prospective multiinstitutional clinical trial.
