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. Patients underwent post-procedural selective graft patency assessment using cardiac catheterization...

OBJECTIVES: Right ventricular (RV) function is impaired after cardiac surgery, possibly because of the opening of the pericardium. In minimally invasive aortic valve replacement, the pericardium is only partially incised. METHODS: A randomized trial compared RV function after ministernotomy versus full sternotomy in 40 adults undergoing aortic valve replacement at the Karolinska University Hospital. Primary outcomes were tricuspid annular plane systolic excursion, RV pulsed-wave tissue Doppler velocity, RV fractional area change and basal and mid-RV transversal diameters on postoperative Days 4 and 40...

Complex cardiac procedures often require blood transfusion because of surgical bleeding or coagulopathy. Thrombelastography (TEG) was introduced in our institution to direct transfusion management in cardiothoracic surgery. The goal of this study was to quantify the effect of TEG on transfusion rates peri- and postoperatively. All patients who underwent complex cardiac surgery, defined as open multiple valve repair/replacement, coronary artery bypass grafting with open valve repair/replacement, or aortic root/arch repair before and after implementation of TEG were identified and retrospectively analyzed...

BACKGROUND: Myxomas are the most frequent cardiac tumours. Their diagnosis requires prompt removal. In our centre, for valve surgery we use a minimally invasive approach. Here, we report our experience of cardiac myxoma removal through right lateral mini-thoracotomy (RLMT) with particular focus on its feasibility, efficacy and patient safety. METHODS: Between February 2006 and January 2017, 30 consecutive patients (aged 66±12.6years, range 35-83 years) underwent atrial myxoma resection through video-assisted RLMT...

Blood pressure (BP), a surrogate of cardiac output (CO), is also dependent on systemic vascular resistance (SVR). But SVR is not routinely monitored in daily clinical practice. We hypothesise that the time difference between the peripheral arterial waveform and the finger plethysmographic waveform (time lag index - TLi) could indicate the systemic vascular resistance. In this study, we correlated TLi with the systemic vascular resistance measured by minimally invasive CO monitor (pulse contour analysis). SVR changes in response to administration of mannitol were studied...

Introduction: Atrial fibrillation is the most common cardiac arrhythmia in the United States. It has been associated with a reduction in patient quality of life and more serious complications such as stroke and heart failure. The aim of this study was to compare the efficacy of commonly performed invasive procedures in keeping patients in normal sinus rhythm. Methods and Results: A retrospective chart review was performed on all patients who underwent primary radiofrequency catheter ablation, the complete Cox-maze, or the hybrid maze at OSF Saint Anthony Medical Center between January 2010 and December 2013 (n=140)...

OBJECTIVE: As the use of minimally invasive surgery in cardiothoracic surgery increases, so does the need for simulation and training. We developed a heart model for simulation and training of minimally invasive cardiac surgery, particularly minimally invasive mitral valve repair using our new three-dimensional printing system. METHODS: Digital imaging and communication in medicine data from patient computed tomography, three-dimensional computer-aided design, and three-dimensional printing helped create replicas of the heart and thoracic cavity...

BACKGROUND: Over the past two decades, minimally invasive techniques for classic heart valve surgery and isolated bypass surgery have been developed that enable access to the heart via partial sternotomy for most aortic valve procedures and via sternotomy-free mini-thoracotomy for other procedures. METHODS: We review the current evidence on minimally invasive cardiac surgery on the basis of pertinent randomized studies and database studies retrieved by a selective search in the MEDLINE and PubMed Central databases, as well as by the Google Scholar search engine...

AIMS: Ring annuloplasty is the gold standard of surgical repair in degenerative mitral valve disease. However, prosthetic annuloplasty has some drawbacks and potential hazards. Suture annuloplasty theoretically is able to preserve annular leaflet dynamics and left ventricular performance, but experience is limited. The aim of the study was to review the early and long-term outcome of the posterior double-suture annuloplasty (DSA) technique for degenerative mitral valve repair. METHODS: From January 2002 to December 2008, 400 patients underwent primary mitral valve repair for degenerative disease either with posterior DSA [n = 147 (37%)] or with flexible posterior annuloplasty band [n = 253 (63%)]...

The field of minimally invasive cardiac surgery has undergone rapid transformation over recent years. In this review, we provide a summary of the most current evidence supporting the use of minimally invasive aortic and mitral valve replacement techniques, as well as transcatheter approaches for aortic and mitral valve disease. As an adjunct, the use of robotically assisted coronary bypass surgery and hybrid coronary revascularization procedures is discussed. In order to obtain optimal patient outcomes, a collaborative, heart-team approach between cardiac surgeons and interventional cardiologists is necessary...

Jerold S Shinbane, Leslie A Saxon
Advances in imaging technology have led to a paradigm shift from planning of cardiovascular procedures and surgeries requiring the actual patient in a "brick and mortar" hospital to utilization of the digitalized patient in the virtual hospital. Cardiovascular computed tomographic angiography (CCTA) and cardiovascular magnetic resonance (CMR) digitalized 3-D patient representation of individual patient anatomy and physiology serves as an avatar allowing for virtual delineation of the most optimal approaches to cardiovascular procedures and surgeries prior to actual hospitalization...

BACKGROUND A Bochdalek hernia (BH) is a rare congenital condition consisting of a posterolateral defect in the diaphragm. A para-esophageal hernia (PEH) is a rare variant of hiatus hernia. BH and PEH may present with gastric volvulus or incarceration, requiring emergency treatment. Minimally invasive surgery is the preferred treatment, particularly for elderly patients and patients with comorbidities. The occurrence of BH with concomitant PEH is a very rare event. We describe a case of an octogenarian patient with BH and concomitant PEH treated laparoscopically...

RATIONALE: The knee joint is an important weight-bearing joint, tibial plateau fractures affect knee function and stability. High-energy intra-articular fractures involving the tibial plateau can cause management-related problems such as wound dehiscence; severe comminution leading to malalignment; and delayed complications such as varus collapse, implant failure, and arthritis of the knee joint. The treatment of severe or complex tibial plateau fractures can be quite difficult. Traditional methods of open reduction and plating require extensive exposures, which may further compromise soft tissue and devascularize bone fragments, leading to infection...

BACKGROUND: Cardiac output (CO) is an important haemodynamic parameter to monitor in patients during surgery. However, the majority of the techniques for measuring CO have a limited application in veterinary practice due to their invasive approach and associated complexity and risks. Transoesophageal echocardiography (TEE) is a technique used to monitor cardiac function in human patients during surgical procedures and allows CO to be measured non-invasively. This prospective clinical study aimed to compare the transoesophageal echocardiography using a transgastric view of the left ventricular outflow tract (LVOT) and the thermodilution (TD) technique for the assessment of CO during mean arterial pressure of 65-80 mmHg (normotension) and <65 mmHg (hypotension) in dogs undergoing elective surgery...
