Objective The purpose of this study was to develop a new method for minimally invasive mitral valve repair under direct endoscopic visualization in the beating heart. Methods Fiberoptic cardioscopy of the left heart was conducted in 12 calves. Systemic perfusion was maintained by cardiopulmonary bypass through a median sternotomy. A clear solution (Ringer's lactate) was temporarily administered via the pulmonary artery to flush out the pulmonary vasculature, and additional perfusion of the left heart chambers enhanced visualization of the intracardiac anatomy. The endoscope, with an open-ended transparent flexible outer sheath, was inserted through the left ventricular apex, and an endoscopic clip was used for edge-to-edge mitral valve repair. Hemodilution was avoided by the drainage of irrigation fluid via a left ventricular cannula. Results Direct endoscopic visualization of the mitral valve in an in vivo beating heart was obtained clearly, avoiding systemic hemodilution. In the last experiment, edge-to-edge repair using an endoscopic clip was successfully performed. Use of an effective intracardiac irrigation method was important for successful image acquisition and achievement of repair procedures. Conclusions This acute animal study showed the technical feasibility of beating-heart mitral valve surgery under direct endoscopic imaging. Although this study was performed under open-chest conditions, our successful experiment is a first step toward closed-chest intracardiac surgery with direct endoscopic visualization.

The patient was a 66-year-old woman who had undergone laparoscopic cholecystectomy (Lap-C) secondary to chronic cholecystitis status post endoscopic choledocholithotomy 13 months previously. During surgery, Hem-o-Lok clips were used to control the cystic duct and the cystic artery. Due to the presence of extensive adhesions of the cystic duct and surrounding tissue, the surgeons had difficulty in debriding the area. Thirteen months after Lap-C, the patient underwent a screening esophagogastroduodenoscopy (EGD), which demonstrated clip appearance at the inferior wall of the first part of the duodenum. In the EGD, duodenal erosions and edema were observed around the clip. We appreciated that endoscopic clip removal would be difficult because of the presence of severe adhesions and inflammation of the duodenal bulb. On clinical examination of the patient, no major abnormalities or physical findings were noted. Therefore, we decided not to attempt to remove the clip. The patient was treated with an oral proton pump inhibitor to prevent extensive duodenal mucosal injury. Two months later, we repeated the EGD, which revealed that the clip was no longer present, and the duodenum was covered with normal mucosa surrounding the scar. Abbreviations: EGD: esophagogastroduodenoscopy; Lap-C: laparoscopic cholecystectomy; PPI: proton pump inhibitor.
