Successful repair of a bicuspid aortic valve with anomalous chordal attachment to the aortic wall.
The congenitally bicuspid aortic valve with anomalous chordal attachment of the fused cusp to the aortic wall is a rare and unappreciated cause of aortic insufficiency. We report the case of a 43-year-old male patient who presented with severe aortic insufficiency caused by this anomaly and in whom surgical aortic valve repair was successfully performed. To our knowledge, this is the first report to describe the successful surgical repair of this rare variant of bicuspid aortic valve.

Many studies have demonstrated that patients with metachronous second primary lung cancer (MSPLC) benefit from surgery. Owing to the lack of uniform criteria and prospective randomized trials, the extent of resection remains controversial, and prognostic factors are still not fully clear. The present study aimed to assess surgical treatment of MSPLC and identify prognostic factors of outcome. ⋯ Surgical treatment of MSPLC is safe and effective. TNM stage I, tumor size 2 cm or less, or less than 20 pack-years smoking are predictors of improved survival. Sublobar resection is acceptable. For stage I disease, lobectomy tends to be associated with better survival than sublobar resection, although the difference is not significant, and completion pneumonectomy is not recommended. Long-term follow-up is necessary even after curative resection of lung cancer.

Surgery in patients with Kommerell diverticulum (KD) is controversial. Although the presence of symptoms is an accepted indication, the KD itself may be a risk factor for dissection and rupture, although size criteria for operation are undefined. ⋯ This is the largest reported single-center experience with the surgical management of KD in adults, verifying its safety and efficacy. The high percentage of KD with medial degeneration suggests asymptomatic patients with an enlarged KD also may benefit from resection.

The Sorin Freedom SOLO (FS) bovine pericardial stentless valve prosthesis is designed for supraannular, subcoronary implantation. We report our experience and results with 277 consecutively implanted FS bioprostheses. ⋯ The FS stentless aortic valve is safe to implant, and it shows excellent hemodynamic performance and early and midterm results. Owing to the favorable EOA, the valve appears particularly attractive for patients at risk for PPM.

Interfacility transport of patients on extracorporeal membrane oxygenation (ECMO) has been performed in large numbers at only a few programs. Limited data are available on outcomes after ECMO transport to justify expanding or discontinuing these programs. ⋯ Interfacility transport on ECMO is feasible and can be accomplished safely in the critically ill. Survival of transported patients is comparable to age-matched and treatment-matched ECMO patients at large.
