Abstract	We experienced 3 cases of port-access robot-assisted totally endoscopic technique for mitral valve repair and concomitant coronary artery bypass. The right internal mammary artery was harvested, mitral valve was fixed, and the right internal mammary artery to right coronary artery anastomosis was carried out on the arrested heart. The use of cardiac arrest and a V-shaped hook technique facilitated the coronary anastomosis and the da Vinci Firefly test (Intuitive Surgical Inc., Sunnyvale, CA) could confirm patency of the graft.

Abstract	We herein report a case of a 20-year-old man with aortic regurgitation (AR), coarctation of the aorta (CoA), and patent ductus arteriosus (PDA). The preoperative ankle-brachial pressure index was 0.56 in bilateral extremities. Enhanced computed tomography revealed CoA-postductal type. We decided to perform a two-stage surgery: thoracic endovascular aortic repair (TEVAR) for CoA and PDA and then open surgery for AR. TEVAR was successfully performed with deployment of the stent graft at a 31-mm diameter subsequent to balloon dilation. At 8 days after TEVAR, the patient underwent aortic valve replacement via median sternotomy and was discharged without a complication.

Abstract	A 21-year-old female patient referred to our institute had been suffering from severe mitral valve regurgitation due to a rare anomaly: a typical cleft at the posterior mitral leaflet and the other partial one at the anterior leaflet. We successfully fixed the mitral valve using the robot-assisted totally endoscopic technique which could perform suture closure of both leaflets and annuloplasty. This communication is the first report of the robotic and totally endoscopic procedure which could treat this rare mitral anomaly.

Abstract	Papillary fibroelastoma is a benign tumor of the heart, constituting less than 10% of heart tumors. When papillary fibroelastoma is diagnosed, surgical treatment must be considered because it may cause embolization such as myocardial infarction and strokes. We experienced a patient with papillary fibroelastoma of the tricuspid valve after total resection of the right breast for breast cancer and partial lung resection for lung cancer. Minimally invasive cardiac surgery (MICS) with right thoracotomy was perfomed to resect the tumor. Though median sternotomy is still the most widely used approach for cardiac tumor, MICS is a useful method for preventing sternal wound infection and promoting wound healing, particularly in a patient with high risk of wound infection like this case.

Abstract	To avoid aortic cross-clamping and cardioplegic ischaemia, we propose the induction of hyperkalemic arrest and using aortic no-touch technique in minimally invasive atrial septal defect (ASD) closure. Twenty-eight patients were included in this study. After establishment of cardiopulmonary bypass, potassium was administered to induce hyperkalemic arrest. The mean dose of injected potassium was 1.2 ± 0.45 mEq/kg. Following the direct closure of the ASD, potassium was filtered out using a hemodialyzer. At the end of the operation, serum potassium was normalized to 4.1 ± 0.5 mEq/l. The mean arrest time was 11 ± 4.4 min without complications. Hyperkalemic arrest in combination with aortic no-touch technique is safe and efficacious in minimally invasive ASD closure.

Abstract	Isolated coronary artery bypass grafting associated with atrial fibrillation is routinely performed through a sternotomy, and cardiac arrest. Advancements in this surgical approach have led to better cosmesis, a quick postoperative recovery, with the same postoperative results. We report a case of a novel, less invasive hybrid treatment combining robot-assisted coronary artery bypass grafting and percutaneous radiofrequency catheter ablation.

Abstract	Pectus excavatum (PE) can be associated with cardiac disorders that also require surgical repair. Totally endoscopic robot-assisted mitral valve plasty for mitral valve regurgitation was performed while elevating the sternum with the aid of our original electrical sternum lifting system. Then, the Nuss procedure was performed successfully via small incision. Simultaneous robot-assisted cardiac surgery and the Nuss procedure is effective. Sternal elevation during cardiac surgery is very important for a safe procedure. The Nuss technique prevents perioperative cardiac compression and allows for correction of the pectus deformity with good cosmetic and functional results.

Abstract	Objective: Ventricular septal rupture (VSR) is a severe complication of acute myocardial infarction, and the conventional technique for repair is associated with high operative mortality. A novel intraventricular stent graft (IVSG) device was tested as a less invasive treatment for VSR; it does not require cardiopulmonary bypass, cardiac arrest, or left ventricular incision. Its effectiveness was assessed using animal experiments. Methods: Six pigs were placed on cardiopulmonary bypass. The VSR model was created by making a hole in the interventricular septum via the right ventricle. Animals were weaned off the bypass. The sheath encasing the device was advanced over the guidewire, and the IVSG was placed in the left ventricle. Before and after rupture creation and after device deployment, left ventriculography was performed, hemodynamic data were collected, and Qp/Qs values were measured. Results: All procedures were completed safely. The left-to-right shunt seen after rupture creation disappeared after device deployment. The pulmonary-to-systemic blood flow ratio after rupture was 3.35 ± 1.00, decreasing significantly to 1.09 ± 0.10 after device deployment (P = 0.007). Hemodynamic instability after rupture creation improved dramatically after deployment. Conclusions: The use of our new IVSG in this VSR animal experiment model significantly decreased the left-to-right shunt. The new device was able to control the acute heart failure associated with VSR with a minimally invasive procedure during the hyperacute phase of heart failure. Potential improvements in VSR treatment outcomes are expected with its clinical application.

Abstract	Peroral cholangioscopy-guided lithotripsy is highly effective in clearing difficult bile duct stones. It can cause adverse events, such as cholangitis and pancreatitis; however, gallbladder perforation is extremely rare. Herein, we describe the case of a 77-year-old woman who developed gallbladder perforation following peroral cholangioscopy -guided lithotripsy. She was referred to our hospital to treat multiple large bile duct stones. She underwent peroral cholangioscopy-guided lithotripsy because of conventional lithotripsy failure. After a cholangioscope was advanced into the bile duct, saline irrigation was used for visualization. Electronic hydraulic lithotripsy was performed, but it took time for fragmentation because the calculus was hard. The 2-h endoscopic procedure did not completely remove the stone, and treatment was discontinued after placing a biliary plastic stent and nasobiliary tube. After the endoscopic procedure, she started experiencing right hypochondrial pain, which worsened the next day. Computed tomography showed a gallbladder wall defect in the gallbladder fundus with pericholecystic fluid. She was diagnosed with gallbladder perforation and underwent emergency surgery. A perforation site was found at the gallbladder fundus. Open cholecystectomy, choledochotomy, and extraction of residual bile duct stones were performed. The patient was discharged 9 days post-surgery without any complications. The saline irrigation used for visualization may have caused a surge in intra-gallbladder pressure, resulting in gallbladder perforation. Therefore, endoscopists may need to conserve irrigation water during peroral cholangioscopy-guided lithotripsy.
