Mitral Valve Repair Outcomes in a Community Hospital: A Retrospective Analysis.

BACKGROUND: The results of mitral valve repair operations conducted at community hospitals in rural states are not well studied or reported in the literature. METHODS: We retrospectively assessed consecutive patients who underwent isolated mitral valve repair operations performed by a single experienced cardiothoracic surgeon at a large community hospital from May 1, 2006 - April 30, 2010. Patients were monitored for up to three years (average 2.2 years) following surgery for a variety of surgical variables, including morbidity, mortality, and serial two-dimensional transthoracic echocardiographic findings. Comparisons were made with the Society of Thoracic Surgeons Adult Cardiac Surgery Database (ACSD). RESULTS: Sixty-three consecutive patients underwent isolated complex mitral repair operations. Echocardiographic and morbidity data demonstrated successful outcomes, with no operative mortality and a single cardiac-related death within three years postoperatively. Other variables, especially those that relate to post-repair outcomes, showed no significant differences between our patients and comparison data from the ASCD. CONCLUSIONS: Our study demonstrates equivalent risks and outcomes for complex mitral valve repair performed in a community hospital setting as those found in a national database. The appropriate institutional setting for performing highly complex procedures has substantial implications for health policy, especially regarding access and quality issues.

Radial artery harvest using endoscopic techniques.

BACKGROUND: Endoscopic vessel harvest for coronary artery bypass conduit has become a routine procedure. With the advancement of endoscopic equipment, radial arteries can be safely harvested with excellent cosmetic results. METHODS: One hundred consecutive patients undergoing coronary artery bypass grafting underwent endoscopic radial artery harvest without complications requiring intervention. The vessel was accessed through a 3-cm long, longitudinal incision performed several millimeters medial to the palpated artery to avoid the lateral antebrachial cutaneous nerve. Commercially available endoscopic retractors, using ultrasonic or direct-current shears, were used to ligate side branches and mobilize the pedicled artery and satellite veins. Ligation was performed with clips at the wrist, endo-loops proximally, and endoshears for transection. RESULTS: Patient age ranged from 42 to 88 years; 70% of the patients were men, and 26% were diabetic. Le f t radial arteries were preferentially harvested. All arteries were used and no further conduit was needed because of inadequate length. In 2 patients subcutaneous hematomas formed postoperatively and resolved without exploration. Although some thenar dysthesia was present in 14 patients, no permanent neurovascular injuries occurred. There were no infections, although skin edges did get traumatized from the retractor. COMMENT: Radial arteries can be harvested in a reproducible, safe, and efficient manner wi th less morbidity and better patient satisfaction.

Cost-effective endoscopic radial artery harvesting.

Radial artery harvesting has been routinely performed by endoscopy. We present a reduced cost technique using a reusable retractor and thermal welding shears. The combination of reusable and disposable tools allows patients to benefit from endoscopic radial artery harvesting with decreased morbidity and favorable cosmetic results.
