Objective: Port sites are a common source of perioperative bleeding in robotic cardiac surgery, which can be exacerbated by patient anatomy and anticoagulation. We present results from the liberal usage of a balloon-tipped coudé catheter for tamponade of robotic port sites during robotic mitral surgery.

Methods: All patients who underwent robotic mitral valve surgery at our institution from August 2016 to July 2022 were studied ( = 320).

Introduction: Peritoneal mesothelioma is an extremely rare malignancy of the peritoneum. It has a poor prognosis, and the optimal systemic chemotherapy remains controversial. Here, we report two cases of peritoneal mesothelioma with long-term survival and complete response to carboplatin, pemetrexed, and bevacizumab chemotherapy.

Robotic cardiac surgery continues to evolve, offering patients a less invasive alternative to traditional median sternotomy, even for complex procedures. This report presents a case of robotic totally endoscopic aortic valve replacement using a rapid deployment valve combined with mitral valve repair, demonstrating the feasibility and safety of this approach.

Objective: Reverse hybrid coronary revascularization (RHCR) is the integration of percutaneous coronary intervention (PCI) followed by sternal-sparing coronary artery bypass grafting in patients with multivessel coronary artery disease (CAD). We sought to review our RHCR experience over a 10-year period using PCI first followed by robotic totally endoscopic coronary artery bypass (TECAB).

Methods: We reviewed the indications and outcomes in patients who underwent RHCR (PCI with drug-eluting stents first, followed by TECAB).

Objective: Although robotic cardiac surgery is becoming more widely adopted for mitral valve procedures, robot-assisted tricuspid valve (TV) surgery is less common. We describe clinical and echocardiographic outcomes for 70 isolated and concomitant TV repair (TVr) cases.

Methods: Patients who underwent robotic totally endoscopic TV surgery at our institution were retrospectively reviewed.

Article Synopsis
  • The video tutorial explains robotic totally endoscopic Cryo-Maze ablation, a surgical procedure used to treat atrial fibrillation.
  • It involves using advanced robotic technology to perform the procedure with minimal invasiveness.
  • The surgery is conducted under moderate hypothermic ventricular fibrillatory arrest to enhance patient safety and effectiveness of the treatment.

Objective: Myocardial bridging (MB) occurs when a coronary artery, commonly the left anterior descending (LAD), has an intramyocardial course. In symptomatic patients who fail medical therapy, surgical unroofing can provide symptomatic relief by improving coronary blood flow. We present a series of patients undergoing robotic totally endoscopic beating-heart MB unroofing.

Surgical robots have been utilized to facilitate a truly minimally invasive approach in cardiac surgery. Robotic aortic valve replacement allows for a totally endoscopic approach with better visualization in a wider range of patients with varying anatomies. It has the potential advantages of faster functional recovery and superior cosmetic outcomes compared to traditional sternotomy or thoracotomy approaches.

Background: In 2013, we initiated a comprehensive multispectrum robotic cardiac surgery program with emphasis on the totally endoscopic approach. We reviewed the outcomes of mitral valve (MV) procedures within this context.

Methods: A retrospective review of 1714 robotic endoscopic cardiac surgeries performed at our institution between September 2013 and February 2024 was conducted.

Background: Multi-arterial grafting (MAG) with bilateral internal thoracic arteries (BITAs) is superior to single internal thoracic artery (ITA) and veins, however, sternal wound infection (SWI) is a deterrent to using BITA, especially in diabetic and obese patients. Sternal-sparing approaches, including robotic totally endoscopic coronary artery bypass (TECAB), may mitigate this risk. We reviewed outcomes of robotic TECAB with BITA grafting.

Objective: Robotic beating-heart totally endoscopic coronary bypass (TECAB) is performed using single or bilateral internal thoracic arteries with good results. Despite slow adoption and limited industry support, we have evolved our practice and continue to routinely perform TECAB. We describe our series of 874 patients undergoing robotic beating-heart TECAB with up to 10-year follow-up.

Unlabelled: A 56-year-old female diagnosed with hypertrophic obstructive cardiomyopathy and myocardial bridge (MB) of the left anterior descending (LAD) coronary artery underwent septal myectomy with resolution of her left ventricular outflow tract gradient. She had ongoing refractory symptoms of exertional angina and fatigue for over a decade and finally presented to our clinic to be re-evaluated for treatment. Provocative angiographic testing confirmed significant ischemia secondary to LAD MB.

Objective: There can be anatomical constraints on patient selection for minimally invasive surgery. For example, robot-assisted coronary artery bypass was reported to be more challenging when patients had a cardiothoracic ratio >50% and a sternum-vertebra anteroposterior and transverse diameter ratio <0.45.

Objective: Femoral artery cannulation is the most commonly used approach for cardiopulmonary bypass (CPB) in robotic cardiac procedures. However, without adding a distal perfusion cannula, leg ischemia can occur in up to 11.5% of patients.
