Reason and Timing for Conversion to Sternotomy in Robotic-Assisted Coronary Artery Bypass Grafting and Patient Outcomes.

Objective: Conversion to sternotomy is a primary bailout method for robotically assisted coronary artery bypass grafting procedures. The aims of this study were to identify the primary reasons for conversion from robotically assisted coronary artery bypass grafting to sternotomy and to evaluate the in-hospital outcomes in such patients.

Methods: Prospectively collected data from February 2004 to April 2017 were reviewed for 72 patients (56 men; mean age = 63.

Robotic-assisted coronary artery bypass surgery: an 18-year single-centre experience.

Background: Minimally invasive robot-assisted direct coronary artery bypass (RADCAB) has emerged as a feasible minimally invasive surgical technique for revascularization that might offer several potential advantages over conventional approaches. We present our 18-year experience in RADCAB.

Methods: Between February 1998 and February 2016, 605 patients underwent RADCAB.

A Prospective Randomized Study of Endoscopic Versus Conventional Harvesting of the Radial Artery.

Objective: The aims of the study were to determine whether endoscopic harvesting of the radial artery (RA) reduces morbidity due to pain, infection, and disability with improvement in satisfaction and cosmesis compared to the conventional technique and (2) to compare the 6-month angiographic patency of the RA harvested conventionally and endoscopically.

Methods: In a prospective randomized study, 119 patients undergoing coronary artery bypass grafting using the RA were randomized to have RA harvested either conventionally (n = 59) or endoscopically (n = 60).

Results: Radial artery harvest time (open wound time) was significantly reduced in the endoscopic group (36.

Long-term patency of endoscopically harvested radial arteries: from a randomized controlled trial.

Objective: From 2005 to 2007, 119 patients were enrolled in a prospective randomized controlled trial comparing open and endoscopically harvested radial arteries for coronary artery bypass grafting. The objective of the current study was to compare graft patency between intervention groups at more than 5 years from the initial trial. We hypothesized that endoscopically harvested radial arteries would show equivalent patency to those conventionally harvested.

The early inflammatory response in a mini-cardiopulmonary bypass system: a prospective randomized study.

Objective: The aim of this study was to compare the early systemic inflammatory response of the Resting Heart System (RHS; Medtronic, Minneapolis, MN USA), a miniaturized cardiopulmonary bypass (CPB) system, with two groups using a standard extracorporeal circulation system during on-pump coronary artery bypass grafting (CABG) surgery.

Methods: A total of 60 consecutive patients requiring CABG were prospectively randomized to undergo on-pump CABG using conventional CPB without cardiotomy suction (group A), conventional CPB with cardiotomy suction (group B), or the RHS (group C). Blood samples were collected at five time points: immediately before CPB, 30 minutes into CPB, immediately at the end of CPB, 30 minutes post-CPB, and 1 hour post-CPB.

Bivalirudin as an anticoagulant for simultaneous integrated coronary artery revascularization - a novel approach to an inherent concern.

Background: Simultaneous integrated coronary artery revascularization combines coronary artery bypass surgery and percutaneous coronary intervention into a single procedure. This approach provides immediate, complete and optimal myocardial revascularization in a less invasive manner. Because simultaneous integrated coronary revascularization necessitates two distinct anticoagulation protocols for the surgical and percutaneous aspects of the procedure, combining these anticoagulation protocols carries a bleeding risk.

Simultaneous integrated coronary artery revascularization with long-term angiographic follow-up.

Objective: Traditionally integrated coronary artery revascularization has been described as a 2-stage procedure. We evaluated the safety and feasibility of 1-stage, simultaneous, hybrid, robotically assisted coronary artery bypass grafting surgery and percutaneous coronary intervention.

Methods: Fifty-eight patients underwent simultaneous, integrated coronary artery revascularization in an operating theater equipped with angiographic equipment.

Computer-enhanced telemanipulation in mitral valve repair: preliminary experience in Canada with the da Vinci robotic system.

Background: Investigation into the surgical application of robot technology continues to expand. We report on the first case series of robotic-assisted mitral valve (RAMV) repair in Canada with use of the da Vinci telemanipulation system (Intuitive Surgical, Sunnyvale, Calif.).

Robotic-assisted left atrial ligation for stroke reduction in chronic atrial fibrillation: a case report.

Patients with atrial fibrillation are at significant risk for sustaining a thromboembolic stroke. More than 90% of thromboemboli form in the left atrial appendage. Ligation of the left atrial appendage to reduce the risk of stroke is often performed in connection with other cardiac surgical procedures.

Concurrent robotic hybrid revascularization using an enhanced operative suite.

Hybrid myocardial revascularization combines coronary surgery with percutaneous intervention as an alternative therapy for ischemic heart disease. The order and sequence of the hybrid approach is not yet clearly defined. We report on the benefits of an enhanced surgical suite equipped with a carbon fiber operating table and digital C-arm for robotic-assisted hybrid revascularization in a single operative sequence.

Robotic Surgery, the First 100 Cases: Where Do We Go from Here?

Abstract Background: Since the robot-assisted cardiac surgery program at this center was initiated in September 1998 the results have been regularly critically evaluated. We report a retrospective review of the first 100 robotic procedures and their evolution. Methods: Between September 1998 and May 2001, 146 patients underwent robot-assisted procedures.

Effect of off-pump coronary artery bypass grafting on risk-adjusted and cumulative sum failure outcomes after coronary artery surgery.

Background And Aim: We have shown that cumulative sum (CUSUM) failure analysis may be more sensitive than standard statistical methods in detecting a cluster of adverse patient outcomes after cardiac surgical procedures. We therefore applied CUSUM, as well as standard statistical techniques, to analyze a surgeon's experience with off-pump coronary artery bypass grafting (OPCAB) and on-pump procedures to determine whether the two techniques have similar or different outcomes.

Methods: In 320 patients undergoing nonemergent, first time coronary artery bypass grafting, preoperative patient characteristics, rates of mortality and major complications, and ICU and hospital lengths of stay were compared between the on-pump and OPCAB cohorts using Fisher's exact tests and Wilcoxon two sample tests.
