Minimally invasive mitral valve operations are increasingly common in the United States, but robotic-assisted approaches have not been widely adopted for a variety of reasons. This expert opinion reviews the state of the art and defines best practices, training, and techniques for developing a successful robotics program.

OBJECTIVE: Primary cardiac tumors most commonly occur in the left atrium. The aim of this study was to compare outcomes among patients undergoing isolated left atrial tumor resection via sternotomy or robotic approach. METHODS: From 2003 to 2013, 69 patients underwent isolated left atrial tumor resection at 3 affiliated hospitals with either a sternotomy (n = 39) or robotic approach (n = 30). A retrospective review of prospectively collected data was performed, and outcomes were compared between the sternotomy and robotic groups...

BACKGROUND: The role of robotic instruments in mitral valve (MV) surgery continues to evolve. The purpose of this study was to assess the safety, efficacy, and scope of MV surgery using a lateral endoscopic approach with robotics (LEAR) technique. METHODS: From 2006 to 2013, a dedicated LEAR team performed 1,257 consecutive isolated MV procedures with or without tricuspid valve repair or atrial ablation. The procedures were performed robotically through five right-side chest ports with femoral artery or ascending aortic perfusion and balloon occlusion...

BACKGROUND: Minimally invasive mitral valve surgery (MIMVS) has become a standard technique to perform mitral valve surgery in many cardiac centers. However, there remains a question regarding when MIMVS should not be performed due to an increased surgical risk. Consequently, expert surgeons were surveyed regarding their opinions on patient factors, mitral valve pathology and surgical skills in MIMVS. METHODS: Surgeons experienced in MIMVS were identified through an electronic search of the literature...

From March 2006 to August 2008, 93 subjects (186 knees) underwent simultaneous bilateral total knee arthroplasty performed by eight surgeons at North American centers. This randomized study was conducted to determine whether non-weight-bearing passive flexion was superior for knees receiving a posterior stabilized high flexion device compared to a posterior stabilized standard device in the contra-lateral knee. Weight-bearing single leg active flexion was one secondary endpoint. Follow-up compliance was 92...

BACKGROUND: Detailed information about how patients with head and neck carcinoma (HNC) are treated across practice settings does not exist. The authors conducted a prospective, observational study to examine the patterns of care for a series of patients with newly diagnosed HNC in the United States and to test 2 hypotheses: 1) There is no difference in the pattern of care between community and academic settings; and 2) the results of major randomized clinical trials will change the pattern of care in both practice settings within 1 year of publication in peer-reviewed journals...

OBJECTIVE: : The purpose of this study was to demonstrate the feasibility of simple to complex endoscopic robotic mitral valve repair, using a lateral approach. METHODS: : Data were retrospectively collected on 201 patients undergoing a lateral "ports only" endoscopic robotic mitral valve repair at three institutions. Techniques of aortic occlusion included the endoaortic balloon or a transthoracic clamp. The efficacy of the repair was measured intraoperatively by transesophageal echocardiogram...

PURPOSE: To examine the effect of an internet-based aid to informed consent on parent recall of potential surgical complications. METHODS: Parents of children scheduled for elective inguinal hernia repair were assigned to a control group or were enrolled in an internet-based program designed to aid in the consent process. Nine potential surgical complications were presented to the parent(s) in the consent discussion and in the Internet program. Parent recall of potential surgical complications was assessed immediately after the consent discussion and on the day of surgery...

OBJECTIVES: To assess patients who had radical prostatectomy (RP) and pelvic lymph node dissection (PLND) for pT2-4 N0M0 prostate cancer, to determine if LN yield affects the risk of biochemical failure (BCF), as the extent of PLND at the time of RP has become increasingly uncertain with the decreasing trend in tumour stage. PATIENTS AND METHODS: We reviewed the Columbia University Urologic Oncology Database for patients with pT2-4 N0M0 prostate cancer treated with RP from 1990 to 2005...

STUDY DESIGN: Clinical practice guideline. OBJECTIVE: To develop evidence-based recommendations on use of interventional diagnostic tests and therapies, surgeries, and interdisciplinary rehabilitation for low back pain of any duration, with or without leg pain. SUMMARY OF BACKGROUND DATA: Management of patients with persistent and disabling low back pain remains a clinical challenge. A number of interventional diagnostic tests and therapies and surgery are available and their use is increasing, but in some cases their utility remains uncertain or controversial...

OBJECTIVE: To determine the safety and efficacy of endoscopic mitral valve surgery using robotic instruments through the lateral right chest. METHODS: We conducted a retrospective review of 127 patients taken to the operating room for endoscopic robotic mitral surgery from December 2002 through November 2005. Mean age was 54 +/- 13 years and 58% were male. Mitral regurgitation was 4+ in 121 patients, 3+ in 4 patients, and 2+ in 2 patients. Nineteen (15%) patients had a left ventricular ejection fraction of 0...

BACKGROUND: Robotic totally endoscopic coronary artery bypass (TECAB) of the left anterior descending artery (LAD) coupled with percutaneous coronary intervention (PCI) of a second coronary artery has been investigated in patients with multivessel disease to provide a minimally invasive therapeutic option. METHODS AND RESULTS: TECAB of the LAD was performed using the left internal mammary artery (LIMA). A second lesion was treated with PCI before surgery, simultaneously, or after surgery...

Traditionally, the role of chemotherapy in the treatment of squamous carcinoma of the head and neck has been confined to patients with recurrent or metastatic disease who are deemed incurable with surgery or radiation therapy. Over the past decade, however, the role of chemotherapy has changed dramatically. The use of primary combined chemoradiation to preserve function or to enhance survival in patients with unresectable disease has become a standard approach. As the use of chemotherapy in squamous carcinoma of the head and neck has expanded, investigators have been interested in identifying new active agents...

In a retrospective analysis of 202 renal transplant procedures in the years 1989-1992 we identified an excess of grafts lost from primary renovascular thrombosis in patients receiving continuous ambulatory peritoneal dialysis (CAPD) compared to haemodialysis (HD) patients (9 CAPD versus 0 HD, Chi-squared = 9.63; P < 0.01). All graft losses from thrombosis occurred within 16 days of surgery. Possible predisposing causes were identified in three patients. Donor age was greater in CAPD patients losing their kidneys from thrombosis compared to the overall CAPD group [mean (SD) years, 43...

PSA (prostate specific antigen) and PSMA (prostate specific membrane antigen) serum levels were determined in over 235 prostate cancer patients from 8 different United States clinical urological cancer centers. The clinical data were not known until after the serum assay results were shared with all participants to attempt to eliminate possible clinical bias. PSA values are useful in the clinical diagnosis and staging of prostate cancer patients, and generally fall to low values in response to effective treatment, e...

The remarkable and colourful career of Sir Douglas Shields of Melbourne is unparalleled among Australian surgeons of his generation: Murray Morton describes it as a romance. He graduated in 1897 and was, in turn, a country general practitioner, the principal medical officer of an overcrowded plague-ship bringing home soldiers from the Boer War, senior surgeon of St Vincent's Hospital, Melbourne then, in London, surgeon-in-chief of his own hospital converted to the 'Hospital for Wounded Officers' with promotion to the ranks of brigadier-general and rear-admiral, then knighted and, finally, a consultant surgeon with private hospitals in Park Lane and in Cannes, and with patients largely drawn from the aristocracy, the rich and the famous...
