    Notes: Abstract Objectives: The study describes the single-center experience using robot-assisted videoscopic mitral valve surgery and the early results with a remote telemanipulator-assisted approach for mitral valve repair. Material and Methods: Out of a series of 230 patients who underwent minimally invasive mitral valve surgery, in 167 patients surgery was performed with the use of robotic assistance. A voice-controlled robotic arm was used for videoscopic guidance in 152 cases. Most recently, a computer-enhanced telemanipulator was used in 15 patients to perform the operation remotely. Results: The mitral valve was repaired in 117 and replaced in all other patients. The voice-controlled robotic arm (AESOP 3000) facilitated videoscopic-assisted mitral valve surgery. The procedure was completed without the need for an additional assistant as “solo surgery.” Additional procedures like radiofrequency ablation and tricuspid valve repair were performed in 21 and 4 patients, respectively. Duration of bypass and clamp time was comparable to conventional procedures (107 Å 34 and 50 Å 16 min, respectively). Hospital mortality was 1.2%. Using the da Vinci telemanipulation system, remote mitral valve repair was successfully performed in 13 of 15 patients. Conclusion: Robotic-assisted less invasive mitral valve surgery has evolved to a reliable technique with reproducible results for primary operations and for reoperations. Robotic assistance has enabled a solo surgery approach. The combination with radiofrequency ablation (Mini Maze) in patients with chronic atrial fibrillation has proven to be beneficial. The use of telemanipulation systems for remote mitral valve surgery is promising, but a number of problems have to be solved before the introduction of a closed chest mitral valve procedure.

    Notes: Abstract  Objectives Redo mitral valve surgery via sternotomy is associated with a substantial morbidity and mortality. This study evaluated a minimally invasive technique for mitral valve redo procedures. Material and Methods: Out of a series of 394 patients undergoing mitral valve repair or replacement via a right minithoracotomy, 39 patients underwent redo mitral valve surgery (59 ± 13 years, 23 female). Previous cardiac surgeries included 17 patients with mitral valve repair, 6 patients with mitral valve replacement, 3 patients with aortic valve replacement, 2 patients with atrial septal defect closure, and 11 patients with coronary artery bypass grafting (CABG). In all cases, femoro-femoral cannulation was performed. The port access technique was applied in patients undergoing redo valve surgery. In patients with prior CABG, the operation was performed using deep hypothermia and ventricular fibrillation. Results: In all cases, sternotomy was avoided. The mitral valve was replaced in 20 patients and repaired in 19. Time of surgery and cross-clamp time were comparable with the overall series (168 ± 73 [redo] vs 168 ± 58 min and 52 ± 21 [redo] vs 58 ± 25 min). Mortality was 5.1%. One patient had transient hemiplegia due to the migration of the endoclamp. All other patients had uneventful outcomes and normal mitral valve function at 3-month's follow-up. Conclusion: Redo mitral valve surgery can be performed safely using a minimally invasive approach in patients with a previous sternotomy. The right lateral minithoracotomy offers excellent exposure. It minimizes the need for cardiac dissection, and thus, the risk for injury. Avoiding a resternotomy increases patient comfort of redo mitral valve surgery.

    Description / Table of Contents: Zusammenfassung Das herkömmliche endoskopische Instrumentarium ist nicht geeignet, mikrochirurgische Gefäßanastomosen in ausreichender Präzision herzustellen. Daher war ein endoskopisch durchführbarer herzchirurgischer Eingriff bisher undenkbar. Mit Hilfe von Telemanipulator-Systemen, das die Bewegungen des Chirurgen computergesteuert von einer Bedienerkonsole auf feine mechanische Instrumente transformiert, lässt sich erstmals eine Präzision erzielen, die endoskopische Eingriffe am Herzen (Bypasschirurgie, Mitralklappenrekonstruktion) ermöglicht. Bisher ist dies nur am kardioplegisch ruhenden Herzen möglich, so dass auch neue kardiopulmonale Bypassverfahren, die einen kardioplegischen Herzstillstand bei geschlossenem Thorax erlauben, notwendig sind (Port Access System, Heartport™, Redwood City, CA, USA). Die ersten koronaren Bypassoperationen sind inzwischen in total endoskopischer Technik durchgeführt worden [1].
    Notes: Summary The rigid design of conventional endoscopic instruments with limited degrees of freedom has not allowed for endoscopic cardiac surgery. Using a surgical telemanipulation system that is operated from a master console, endoscopic coronary artery bypass grafting and mitral valve repair can be performed with high precision. Closed-chest cardiopulmonary bypass systems that allow cardioplegic cardiac arrest are required. After extensive experimental testing a telemanipulation system was used clinically.

    Description / Table of Contents: Zusammenfassung Die terminale Herzinsuffizienz kann nach Ausschöpfung medikamentöser Therapie oft nur mit mechanischer Kreislaufunterstützung beherrscht werden. Besonders die Therapieergebnisse des rechtzeitigen elektiven Einsatzes von pulsatilen kardialen Assist-Systemen als Überbrückung zur Herztransplantation unterstreichen den Erfolg der Behandlungsmethode. Durch die Aufrechterhaltung bzw. die Wiederherstellung einer ausreichenden Zirkulation mittels mechanischer Kreislaufunterstützung kommt es bei vielen Patienten auch zur Erhaltung oder Wiederherstellung einer ausreichenden Organfunktion. Bei Patienten der NYHA-Klasse IV mit Kontraindikation gegen eine Herztransplantation bietet sich die Implantation eines Langzeitsystems als allerdings bisher noch zeitlich limitierte Alternative zur Transplantation. Eine postkardiotomiebedingte Kreislaufunterstützung bietet bei ansonsten infauster Prognose vielen Patienten die einzige Möglichkeit des Überlebens. Wenn Hauptkomplikationen wie Thrombembolie, Blutung und Infektion nicht auftreten, lohnen gute Ergebnisse den hohen personellen und technischen Aufwand. Das postoperative intensivmedizinische und pflegerische Management erfordert eine spezielle Ausbildung der Mitarbeiter einer Intensivstation.
    Notes: Summary Despite medical therapy, chronic heart failure can often only be treated using a mechanical assist system. The results, when using such devices electively, underline that it is an effective therapy. In many patients, “dependent” organs, such as liver or kidneys etc., can regain their usual function soon after adequate circulatory function is reestablished by the mechanical assist system. In patients with NYHA class IV heart failure and contraindications for heart transplantation, implantation of a long-lasting system is an alternative approach, even though available systems do not yet last forever. Post-cardiosurgical implantation of an assist device is the only option in some patients. The good results are rewarding the high technical and personal efforts if no major-complications, such as thromboembolism, bleedings or infections, occur. Postoperative treatment of these patients requires special training of all those involved.
