Background: Robot-assisted valve surgery represents the latest development in the field of minimally invasive approaches. Robotic assistance may provide greater visualization, enhanced dexterity, and greater precision than traditional mini-thoracotomy aortic valve replacement.Methods and Results: Aortic valve replacement operations using the da Vinci Xi Surgical System (Intuitive Surgical Inc., Sunnyvale, CA, USA) were performed on 2 patients, 1 with severe aortic insufficiency and the other with aortic stenosis. Both patients had an uneventful postoperative course and were discharged without any adverse events.Conclusions: Robot-assisted assisted aortic valve replacement appears feasible and safe in limited cases.

Background:This study retrospectively evaluated the long-term patient outcomes and durability of the Mosaic mitral porcine bioprosthesis in the Japan Mosaic valve long-term multicenter study.Methods and Results:The medical records of 390 patients who underwent mitral valve replacement with the Mosaic bioprosthesis at 10 centers in Japan (1999–2014) were reviewed. Patient data were collected using the Research Electronic Data Capture software. Patient survival was determined using the Kaplan-Meier method. Freedom from structural valve deterioration (SVD) and valve-related reoperation and death were determined using actuarial methods. The median (interquartile range [IQR]) age of the cohort was 73 (69–77) years. The median (IQR) follow-up period was 4.83 (1.84–8.26) years. The longest follow-up period was 15.8 years. The 30-day mortality rate was 5.4%. The 12-year actuarial survival rate was 54.1±4.5%, and the freedom from valve-related death was 85.3±3.4%. The freedom from reoperation at 12 years was 74.3±5.7%. The freedom from SVD at 12 years was 81.4±6.6% for patients aged ≥65 years and 71.6±11.1% for those aged <65 years. The median (IQR) mean pressure gradient was 4.1 (3.0–6.0) and 5.6 (4.0–6.7) mmHg at 1 and 10 years, respectively. The median (IQR) effective orifice area was 1.7 (1.4–2.0) and 1.4 (1.2–1.6) cm2at 1 and 10 years, respectively.Conclusions:The Mosaic porcine bioprosthesis offered satisfactory long-term outcomes for up to 12 years.

The 82nd Annual Scientific Meeting of the Japanese Circulation Society was held in Osaka, Japan, on March 23–25, 2018, when the cherry blossoms were just opening everywhere around the venue. This was the 5th Annual Scientific Meeting of JCS in which a cardiovascular surgeon served as Congress Chairperson. The main theme of this meeting was “Futurability: Pioneering the Future of Circulatory Medicine”. The word, futurability, is a neologism of future ability, because we now have to contemplate what constitutes the essence of cardiovascular medicine, how it should develop as medicine for future generations, and how its ability should be displayed. The meeting was favored by splendid weather and the number of participants was recorded as being higher than 18,700. There were heated and profound discussions about the “futurability” of cardiology, cardiovascular surgery, and heart team medical care as well, in every session. The meeting was successfully completed and we sincerely appreciate the great cooperation and support from all affiliates.
