Left atrial myxoma: Unusual presentation as a cystic tumor

Vasileios Ntinopoulos, Stak Dushaj, Daniele Brugnetti, Laura Rings, more

Journal of Cardiac Surgery > 35 > 2 > 511 - 513

Myxomas are the most common cardiac tumors, benign, and usually located in the left atrium. Typically echocardiography reveals a solid tumor, whereas cystic myxomas are rare with only a few cases documented in the literature. We describe the case of a 63‐year‐old, female patient with an unusual presentation of a left atrial myxoma as a cystic tumor.

Skeletonized internal thoracic artery harvesting: a low thermal damage electrosurgical device provides improved endothelial layer and tendency to better integrity of the vessel wall compared to conventional electrosurgery

Alicja Zientara, Paul Komminoth, Burkhardt Seifert, Dragan Odavic, more

Journal of Cardiothoracic Surgery > 2018 > 13 > 1 > 1-8

Background Electrosurgery is fundamental to the precise, fast and bloodless preparation of internal thoracic artery grafts in cardiac surgery. The PEAK PlasmaBlade is a monopolar electrosurgical device that uses pulsed radiofrequency energy to generate a plasma-mediated discharge along an insulated electrode, creating a cutting edge while the blade stays near body temperature. The aim of this study...

Journal of Cardiothoracic Surgery > 2018 > 13 > 1 > 1-7

Background The anomaly of cervical aortic arch is a rare phenomenon first described by Reid in 1914 and categorized by Haughton in 1975. The left cervical aortic arch Type D consisting of an ipsilateral descending aorta and coarctation or aneurysmatic formation of the arch demonstrates a complicated form requiring surgical management. Because of its rarity and unspecific symptoms only few cases are...

Michael T. Ganter, Martin Geisen, Sonja Hartnack, Omer Dzemali, more

BMC Anesthesiology > 2018 > 18 > 1 > 1-7

Background Functional hemodynamic parameters such as stroke volume and pulse pressure variation (SVV and PPV) have been shown to be reliable predictors of fluid responsiveness in mechanically ventilated patients. Today, different minimally- and non-invasive hemodynamic monitoring systems measure functional hemodynamic parameters. Although some of these parameters are described by the same name, they...

Tim A S Kaufmann, Marcus Hormes, Marco Laumen, Daniel L Timms, more

IFMBE Proceedings > World Congress on Medical Physics and Biomedical Engineering, September 7 - 12, 2009, Munich, Germany > 384-387

The cerebral perfusion can be insufficient during Cardio Pulmonary Bypass (CPB) operations. The outflow cannula position influences the flow field in the cardiovascular system, whereby end organ perfusion is affected. There are different cannulation approaches for CPB. A Computational Fluid Dynamics study was initially undertaken to compare cannulation of the ascending aorta, regarding different cannula...

Anatomic and flow dynamic considerations for safe right axillary artery cannulation

Julia Hillebrand, Moritz Anton Konerding, Mathias Koch, Tim Kaufmann, more

The Journal of Thoracic and Cardiovascular Surgery > 2013 > 146 > 2 > 467-471

Neuroprotection is of paramount interest in cardiac surgery. Right axillary artery cannulation is well established in aortic surgery because it significantly improves survival and outcome, but malperfusion of the right brain after direct cannulation has been reported. Anatomically, 4 vessel segments are potentially amenable for cannulation of the subclavian and axillary arteries. Clinical studies...

Surgical left ventricular remodeling leads to better long-term survival and exercise tolerance than coronary artery bypass grafting alone in patients with moderate ischemic cardiomyopathy

Omer Dzemali, Petar Risteski, Farhad Bakhtiary, Eduard Singer, more

The Journal of Thoracic and Cardiovascular Surgery > 2009 > 138 > 3 > 663-668

Optimal treatment strategies for patients with ischemic cardiomyopathy and moderately reduced left ventricular function remain controversial. We assessed the early and midterm outcomes after surgical revascularization alone versus revascularization and additional left ventricular remodeling in these patients.Between 2000 and 2003, 285 consecutive patients with coronary artery disease and moderately...
