Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

OBJECTIVES: Minimal access mitral valve surgery (MVS) has already proved to be feasible and effective with low perioperative mortality and excellent long-term outcomes. However, experience in more complex valve diseases such as infective endocarditis (IE) still remains limited. The aim of this retrospective study was to evaluate early and long-term results of minimal access MVS for IE. METHODS: Data were entered into a dedicated database. Analysis was performed retrospectively for the 8-year period between January 2007 and April 2015...

OBJECTIVE: Current techniques for mitral valve repair (MVR) in Barlow's disease require high level of surgical expertise due to a complex anatomy. A novel and simple standardized technique that particularly considers the pathological changes of the mitral valve in Barlow's disease has been developed. METHODS: Between 2009 and 2013, 22 patients underwent minimally invasive MVR for Barlow's disease and severe mitral regurgitation (MR). A simple, standardized technique was applied, including resection of P2 segment of posterior mitral leaflet (PML) with preservation of the shortest chordae, transfer of the preserved chordae to A2, and implantation of a semi-rigid open ring...

OBJECTIVES: Totally endoscopic minimally invasive mitral valve surgery (MIMVS) is technically demanding and often performed with robotic assistance. We hypothesized that three-port video-assisted thoracic surgery (VATS) would facilitate endoscopic MIMVS and evaluated its feasibility and safety. METHODS: From October 2010 to June 2016, we performed first-time MIMVS in 250 consecutive patients (122 male), with median age of 65 years (54-73 years, 25-75 percentile)...

A right mini-thoracotomy approach may be used for mitral valve repair without compromising clinical outcomes. Compared with conventional sternotomy, there is an increased distance to the cardiac structures from the mini-thoracotomy incision, which makes certain technical acts more demanding. One particular challenge is hemostasis at the antegrade cardioplegia cannula site. We propose a novel technique to remove an antegrade cardioplegia cannula using the COR-KNOT system. This technique negates the need for tying with a knot pusher and reduces the risk of aortic injury and troublesome bleeding...

This paper reports concomitant septal myectomy during minimally invasive aortic valve replacement through a right mini-thoracotomy. A 76-year-old woman was diagnosed as having aortic stenosis with systolic anterior motion of the mitral valve. The bulging septum was exposed by pulling up a traction suture placed at the annulus of the right coronary cusp; the anomalous chordae and muscle bundles attached to the septum were also resected. By setting an adequate intercostal thoracotomy and placing a traction suture, concomitant myectomy was safely performed even through a right mini-thoracotomy...

BACKGROUND: Recent data have highlighted a higher rate of neurological injuries in minimal invasive mitral valve surgery (MIMVS) compared with the standard sternotomy approach; therefore, the role of specific clamping techniques and perfusion strategies on the occurrence of this complication is a matter of discussion in the medical literature. The purpose of this trial is to prospectively evaluate major, minor and silent neurological events in patients undergoing right mini-thoracotomy mitral valve surgery using retrograde perfusion and an endoaortic clamp or a transthoracic clamp...

REVIEW
W Randolph Chitwood
Localized ventricular septal hypertrophy, also known as idiopathic hypertrophic subaortic stenosis or idiopathic hypertrophic subaortic septal obstruction (IHSS), can create severe ventricular outflow obstruction. This often results in a high sub-aortic pressure gradient with potentially lethal symptoms. In 1960, Braunwald described the hemodynamic characteristics of IHSS, and thereafter, Morrow developed a trans-aortic approach to resect a large part of the ventricular septum, enlarging the outflow tract. The Morrow operation has remained the gold standard for surgically treating this pathology...

Significant technological advances have led to an impressive evolution in mitral valve surgery over the last two decades, allowing surgeons to safely perform less invasive operations through the right chest. Most new technology comes with an increased upfront cost that must be measured against postoperative savings and other advantages such as decreased perioperative complications, faster recovery, and earlier return to preoperative level of functioning. The Da Vinci robot is an example of such a technology, combining the significant benefits of minimally invasive surgery with a "gold standard" valve repair...

BACKGROUND: In the past two decades, the introduction of robotic technology has facilitated minimally invasive cardiac surgery, allowing surgeons to operate endoscopically rather than through a median sternotomy. This approach has facilitated procedures for several structural heart conditions, including mitral valve repair, atrial septal defect closure and multivessel minimally invasive coronary artery bypass grafting. In this rapidly evolving field, we review the status of robotic cardiac surgery in Europe with a focus on mitral valve surgery and coronary revascularization...

Background Minimally invasive surgical access through limited sternotomy reduces trauma and morbidity in cardiosurgical patients. However, until now, it is not the standard access for aortic root replacement. This study details our clinic's experience with minimally invasive implantation of valved conduits through partial upper sternotomy and the comparison to conventional full median sternotomy. Methods Between January 2012 and March 2016, a total of 187 patients underwent aortic root replacement with valved conduits in our department...

Optimal exposure of the mitral valve is paramount in minimally invasive surgery (MIS) and a prerequisite for successful mitral valve repair or replacement. We report the concept of a new left atrial retractor (Karl Storz GmbH, Tuttlingen, Germany) dedicated to MIS. The effectiveness of the device was evaluated in a prospective series of 40 patients successfully operated at our institution.
