ABSTRACT
PURPOSE: The Edwards Intuity Elite (EIE; Edwards Lifesciences, Irvine, CA) valve system is a recent surgical aortic valve designed to expedite implantation, facilitate minimally invasive approaches, and provide low gradients, particularly in smaller valve sizes. The report reviews various best practices learned through experience with the EIE valve system. DESCRIPTION: With its sealing frame designed to anchor and seal the valve after resection of the diseased native aortic valve, EIE use differs from that of conventional sutured valves. EVALUATION: Critical technical aspects include patient selection, aortotomy and debridement, valve sizing, guiding suture technique and valve seating and deployment. In addition, special anatomic and pathologic conditions are considered, as well as intraoperative transesophageal echocardiography and postimplantation cardiac rhythm monitoring. CONCLUSIONS: These best practices simplify and standardize the use of the EIE valve system and may benefit surgeons adopting this valve.

We present a simpler and faster way of implanting the Edwards Intuity Elite rapid deployment valve system. Annular sizing and guiding suture placement are performed in the usual manner. After the valve is parachuted down to the annulus, the balloon catheter is detached and a vent catheter is placed through the center hole to maximize exposure of the valve. The guiding sutures are tied down using an automated suture fastening device instead of securing snares. Visualization of the tip of the suture fastener on the annulus ensures proper valve seating. The sealing frame is ballooned, and the valve is deployed.

Widespread adoption of minimally invasive mitral valve repair and replacement may be fostered by practice consensus and standardization. This expert opinion, first of a 3-part series, outlines current best practices in patient evaluation and selection for minimally invasive mitral valve procedures, and discusses preoperative planning for cannulation and myocardial protection.

Techniques for minimally invasive mitral valve repair and replacement continue to evolve. This expert opinion, the second of a 3-part series, outlines current best practices for nonrobotic, minimally invasive mitral valve procedures, and for postoperative care after minimally invasive mitral valve surgery.

Minimally invasive mitral valve operations are increasingly common in the United States, but robotic-assisted approaches have not been widely adopted for a variety of reasons. This expert opinion reviews the state of the art and defines best practices, training, and techniques for developing a successful robotics program.

STUDY OBJECTIVES: This retrospective study of patients who were referred for surgical resection of non-small cell lung cancer (NSCLC) assessed the accuracy and cost-effectiveness of positron emission tomography (PET) with radiolabeled [18F]-2-fluoro-deoxy-D-glucose (FDG) in staging mediastinal lymph nodes (MLNs). DESIGN: From January 2001 to September 2002, 90 patients with suspected or proven NSCLC who had been referred for curative resection were retrospectively reviewed. All patients were without evidence of metastatic disease. Sixty-nine of the 90 patients had undergone thoracic FDG-PET imaging as part of their evaluation and are the focus of this study. Sensitivity, specificity, accuracy, and positive and negative predictive values for metastasis to the MLN were calculated for CT scanning vs FDG-PET scanning. Four algorithms for staging MLN with mediastinoscopy and/or FDG-PET scan were compared. MEASUREMENTS AND RESULTS: Sixty-nine patients underwent preoperative CT and FDG-PET scans, and 32 of 69 patients underwent mediastinoscopy. Fifty-seven patients underwent thoracotomy with complete mediastinal lymphadenectomy. Sensitivity, specificity, accuracy, and positive and negative predictive values for CT scans and FDG-PET scans were 46%, 86%, 78%, 43%, and 87%, and 62%, 98%, 91%, 89% and 92%, respectively. Mediastinoscopy was accurate in 32 of 32 patients (100%). Routine mediastinoscopy remains the most economically reasonable strategy with excellent sensitivity. Selective FDG-PET imaging improved the sensitivity of noninvasive staging for patients with normal MLNs on CT scans. CONCLUSIONS: Selective use of FDG-PET imaging improves staging accuracy compared to CT scanning alone and makes it a cost-effective adjunct to the preoperative staging of NSCLC. However, in patients with adenocarcinoma and MLNs of < 1 cm, FDG-PET scanning cannot yet replace mediastinoscopy.
