Journal of Cardiac Surgery > 36 > 1 > 403 - 405

We present the patient with severe aortic insufficiency (AI) 5 years post left ventricular assist device (LVAD) implantation. His management was complicated with unsuccessful percutaneous aortic valve closure attempt, transcatheter aortic valve replacement (TAVR) implantation with a severe paravalvular leak, eventual valve dislodgment into the left ventricle (LV), and LVAD inflow cannula occlusion...

Direct right ventricular Impella LD implantation enables postoperative ambulation and may avoid sternal re‐entry

Journal of Cardiac Surgery > 35 > 7 > 1700 - 1702

Right ventricular assist devices (RVADs) typically require groin cannulation or sternal re‐entry which can be avoided by direct pulmonary artery implantation with an Impella. We report the first use of the Impella LD as a directly implanted RVAD.

Endoscopic technology has been employed in various surgical specialities to decrease the morbidity of operations and hasten patient recovery (1–3). These procedures are performed through small ports, with visualization achieved by using an endoscopic camera. Unfortunately, there has been little success with endoscopic techniques in the field of cardiac surgery. Despite numerous attempts over the past...

The use of eptifibatide for suspected pump thrombus or thrombosis in patients with left ventricular assist devices

Bethany R. Tellor, Jennifer R. Smith, Sunil M. Prasad, Susan M. Joseph, more

The Journal of Heart and Lung Transplantation > 2014 > 33 > 1 > 94-101

Pump thrombosis in patients with left ventricular assist devices (LVADs) continues to present treatment challenges. Anti-coagulation strategies used to treat this complication are empiric and without firm data for guidance. The addition of a platelet glycoprotein IIb/IIIa inhibitor to intravenous anti-coagulation has been suggested by several case series and recent guidelines. The aim of this study...

Current Outcomes of Simultaneous Carotid Endarterectomy and Coronary Artery Bypass Graft Surgery in North America

World Journal of Surgery > 2010 > 34 > 10 > 2292-2298

Objective Management of patients with concomitant carotid and coronary artery disease has been controversial. Divergent strategies have been employed, including simultaneous carotid endarterectomy and coronary bypass (SCC) versus various staged procedures. Although no strict comparison group is available, this study defines current outcomes of SCC, compared qualitatively to two reference categories...

Weathering the storm: How can thoracic surgery training programs meet the new challenges in the era of less-invasive technologies?

The Journal of Thoracic and Cardiovascular Surgery > 2009 > 137 > 6 > 1317-1326.e1

The introduction of new technologies has shifted some resident index procedures to nonsurgical specialists. We examined the operative case volume of thoracic surgery residents during the last 6 years to objectively identify changes and trends.Program and resident data from 2002 to 2007 were entered into a database and analyzed. Program match information was obtained from the National Resident Matching...

A Perspective on the Surgical Management of Congestive Heart Failure

World Journal of Surgery > 2008 > 32 > 3 > 375-380

Surgical treatment of patients with congestive heart failure (CHF) has steadily advanced from rescue procedures such as aneurysmectomy, rupture repair, ventricular assist devices (VADs), and transplantation to procedures that can prevent or delay the progression of cardiac dysfunction and failure. The latter include operations such as coronary artery bypass grafting (CABG) and mitral valve repair...

Progress Towards a More Physiologic Approach to Donor Heart Preservation: The Advantages of Hyperpolarized Arrest

Michael D. Diodato, Nirav R. Shah, Sunil M. Prasad, Erica L. Racen, more

Journal of Heart and Lung Transplantation > 2005 > 24 > 9 > 1362-1368

The University of Wisconsin (UW) solution is the gold standard for heart preservation but has limitations in terms of both duration and adequacy of protection. Our laboratory has been interested in a more physiologic approach to heart preservation by maintaining the heart at its resting membrane potential (hyperpolarized arrest) with the K _ATP channel agonist pinacidil. This study compared...

Comparison of Skill Training with Robotic Systems and Traditional Endoscopy: Implications on Training and Adoption

Hersh S. Maniar, M. Laurin Council, Sandip M. Prasad, Sunil M. Prasad, more

Journal of Surgical Research > 2005 > 125 > 1 > 23-29

Robotic systems are being used by an increasing number of surgeons. This environment is markedly different from that of traditional surgery and involves videoscopic guidance, remote surgical control, and the loss of haptic feedback. Defining how surgeons learn with these systems is necessary to establish training protocols for this technology. This study compared the learning curve for a robotic surgical...

Surgical robotics: Impact of motion scaling on task performance

Journal of the American College of Surgeons > 2004 > 199 > 6 > 863-868

Robotic systems have been shown to enhance surgical dexterity, and the advantage has been hypothesized to result from the removal of tremor and addition of motion scaling. But these purported gains over traditional laparoscopic instrumentation have not been quantified. This study was designed to compare the surgical accuracy between conventional laparoscopic instruments and a robotic surgical system...

A Prospective Multicenter Trial of Bipolar Radiofrequency Ablation for Atrial Fibrillation: Early Results

The Annals of Thoracic Surgery > 2004 > 78 > 5 > 1665-1670

The Cox-Maze III remains the gold standard for the surgical treatment of atrial fibrillation. However, the “cut-and-sew” technique is time consuming and technically challenging. The pulmonary veins are the source of ectopy in the majority of patients with atrial fibrillation. The safety and efficacy of bipolar radiofrequency to electrically isolate the pulmonary veins was evaluated in a prospective...
