RESUMEN
We demonstrate the usefulness of two- and live/real time three-dimensional transesophageal echocardiography in a procedure, which combined transcatheter mitral valve-in-valve deployment and paraprosthetic leak closure in the same setting using the less invasive transfemoral approach in an adult patient with bioprosthetic mitral valve degeneration. We also highlight the additive value of three-dimensional echocardiography over the two-dimensional technique.

Robotic cardiac surgery was FDA-approved in 2002 and since then several different procedures have been performed to facilitate a truly minimally invasive approach. The use of robotics in aortic valve surgery, however, is still in its infancy. In this article, we report our clinical experience and chronological development with robot-assisted aortic valve surgery. This includes a description of how robotic assistance was gradually integrated during right mini-thoracotomy aortic valve replacement, a series of cases in which the robot was docked for parts of the procedure, a single case of a totally endoscopic robot-assisted aortic valve replacement with a stentless valve, and three cases of aortic valve papillary fibroelastoma resections. All of these were performed safely with early postoperative recovery and excellent clinical results. Additionally, we review the latest literature describing robot-assisted aortic valve surgery. Finally, we describe current issues, and challenges for robot-assisted aortic valve surgery.

Minimally invasive, robotic-assisted cardiac surgery has been shown to decrease transfusion rates, decrease wound infection rates, shorten hospital length of stay, and allow for a faster return to full activity compared with traditional sternotomy approaches. However, its application has chiefly been limited to primary, isolated procedures such as primary mitral valve repair or replacement. We describe the first reported use of a robotic surgery platform to perform reoperative mitral valve replacement using a minimally invasive, totally endoscopic, port-access approach.

Closure of the left atrial appendage (LAA) has become a standard part of any mitral valve operation because it is thought to reduce the potential for late thrombus development and for embolic events. To date, surgeons performing robotic mitral valve operations have been limited to an endocardial approach to LAA closure. However, oversewing the orifice of the LAA is time consuming and lengthens the cross-clamp time, and failures to obtain permanent closure have been reported. We describe our technique for an epicardial approach that is safe and efficient and that gives a secure closure of the LAA.

An 89-year-old man and an 80-year-old woman were treated surgically for critical aortic stenosis secondary to senile calcific aortic disease and high-grade calcified lesions in the ostium of the right coronary artery. Minimally invasive aortic valve replacement and concurrent coronary artery bypass grafting were performed concurrently through a 5-cm right anterior thoracotomy in the second intercostal space. Surgery was uncomplicated in both cases, with no adverse events. Both patients were alive and well at midterm follow-up. Concurrent minimally invasive aortic valve replacement and coronary artery bypass grafting can be performed successfully through a limited right anterior thoracotomy.

The presence of partial anomalous pulmonary venous return and/or persistent left superior vena cava (LSVC) is usually viewed as a contraindication for robotic repair of complex atrial septal defects, such as those of the sinus venosus type. Three patients, aged 29, 73, and 23 years, successfully underwent totally endoscopic, robotic-assisted repair of sinus venosus-type atrial septal defect with partial anomalous pulmonary venous return and persistent LSVC. Two different techniques--direct cannulation or placement of a sump sucker--were successfully used to manage venous return from the persistent LSVC.

BACKGROUND: Robotic mitral valve repair has been successfully performed since the late 1990s, but concomitant robotic tricuspid repair has not yet been widely adopted. We report our first 5 years' experience with concomitant robotic mitral-tricuspid valve repair. METHODS: Records were reviewed for all patients who underwent concomitant robotic mitral-tricuspid valve repair in a single practice. Cardiopulmonary bypass was performed with femoral cannulation, antegrade and retrograde cardioplegia, and aortic cross-clamping by balloon occlusion. Access was through 5 ports. Tricuspid repair techniques included De Vega, modified De Vega with annuloplasty band, and annuloplasty band with interrupted suture repair. RESULTS: From August 2006 to December 2011, 50 patients underwent concomitant robotic mitral-tricuspid valve repair. The mean age was 73.4±9.3 years, and all patients had mitral or tricuspid regurgitation grades of 2+ or greater preoperatively. Cross-clamp and cardiopulmonary bypass times decreased significantly with surgeon experience. There were no conversions to sternotomy and one conversion to mitral valve replacement. Six patients required reexploration for bleeding or hemothorax, most of them early in the series. There were no infections, no intraoperative strokes, and no new-onset acute renal failure requiring dialysis. Two postoperative strokes resolved completely. Two patients experienced nitinol clip fracture and mitral ring dehiscence requiring reoperation. There were 2 early deaths. All patients had regurgitation grades of less than 2 at follow-up (p < 0.001). CONCLUSIONS: Combined robotic mitral-tricuspid valve repair can be performed safely and reproducibly, with acceptable early results. Long-term follow-up will be needed to establish this as an alternative to traditional sternotomy approaches.

BACKGROUND: The St Jude Medical Epic heart valve (St Jude Medical, Inc, St Paul, Minn) is a tricomposite glutaraldehyde-preserved porcine bioprosthesis. The St Jude Medical Biocor porcine bioprosthesis is the precursor valve to the St Jude Medical Epic valve. The Epic valve is identical to the Biocor valve except that it is treated with Linx AC ethanol-based calcium mitigation therapy. METHODS: The St Jude Medical Epic valve was implanted in 761 patients (mean age 73.9 ± 9.2 years) between 2003 and 2006 in the US Food and Drug Administration regulatory study in 22 investigational centers. The position distribution was 557 aortic valve replacements, 175 mitral valve replacements, and 29 double valve replacements. Concomitant coronary artery bypass grafting was performed in 50.8% of patients undergoing aortic valve replacement and 36.6% of those undergoing mitral valve replacement. RESULTS: The early mortality was 3.6% in aortic and 2.3% in mitral valve replacement. The follow-up was 1675.5 patient-years with a mean of 2.2 ± 1.2 years/patient. Late mortality was 5.2%/patient-year in aortic and 6.6%/patient-year in mitral valve replacement. The late major thromboembolism rate was 0.98%/patient-year for aortic and 2.6%/patient-year for mitral valve replacement. There were 19 reoperations, including 2 for structural valve deterioration, 1 for thrombosis, 9 for nonstructural dysfunction, and 7 for prosthetic valve endocarditis. The actuarial freedom from reoperation owing to structural valve deterioration for aortic valve replacement at 4 years for age 60 years or less was 93.3% ± 6.4%; for ages 61 to 70 years, 98.1% ± 1.9%; and for older than 70 years, 100% (P = .0006 > 70 vs ≤ 60 years). There were no events of structural deterioration with mitral valve replacement. The actuarial freedom from major thromboembolism for all patients at 4 years was 93.6% ± 1.0%. The 2 cases of structural valve deterioration occurred in aortic valves that became perforated without calcification causing aortic regurgitation. CONCLUSIONS: The performance of the St Jude Medical Epic porcine bioprosthesis is satisfactory at 4 years for both aortic and mitral valve replacement. This study establishes the early clinical performance including durability of this porcine bioprosthesis.
