A new left atrial retractor for minimally invasive mitral

A new left atrial retractor for minimally invasive mitral

Introduction: The recent boost of the minimally invasive techniques for mitral valve surgery has led to the development of a dedicated surgical outfit, including retractors, arterial and venous cannulas, and surgical instruments. An effective left atrial retractor is crucial, since an optimal exposure is a prerequisite for a successful mitral valve repair.

 · Minimally-invasive mitral valve surgery has been in development during the last thirty years and now allows to perform mitral and tricuspid interventions, coronary bypass surgery, repair of congenital heart defects and more. Current state-of-the-art technology and clinical knowledge make possible to offer this approach in expert centers to a growing number of patients, who benefit from its .

Heart Double Valve: Causes, Symptoms and Recovery I

Heart Double Valve: Causes, Symptoms and Recovery I

The diseased or damaged valves are not able to open and close properly, thus allowing the mixing and backflow of blood (regurgitation). A double valve replacement surgery mainly aims at correcting the problem of valvular heart disease and involves both aortic valve replacement and mitral valve replacement.

 · The retractor was then stabilised with a Codman retraction system. Exposure of the mitral valve was satisfactory in all cases and the mitral operation was then performed as usual with the visual aid of the Olympus ® endoscope. In 11 cases (4.6%), surgical treatment of atrial fibrillation was associated using either crioablation or microwave .
