Extracardiac Fontan Operation Through a Right Thoracotomy.

An extracardiac Fontan operation through a right thoracotomy incision is an alternative approach in children who have an ascending aorta that is in close proximity to the sternum, as in aortic atresia or transposed great vessels, and in those who have had prior mediastinitis.

Repair of Circumflex Aortic Arch in an Adult.

We describe the diagnoses and repair of a symptomatic circumflex aortic arch in an adult.

Contained Rupture of Sinus of Valsalva Aneurysm in a 64-Year-Old Man.

We report a contained rupture of a right coronary sinus of Valsalva aneurysm, in which repair resulted in symptomatic improvement. Patients often present with symptoms secondary to rupture of the sinus of Valsalva aneurysm into one of the cardiac chambers, or secondary to the compression of adjacent structures. Whereas sinus of Valsalva aneurysms and their rupture are well reported in the literature, contained ruptures have been described only rarely.

Quadruple Vessel Coronary Artery Bypass Grafting in a 14-Year-Old Child With Plasminogen Activator Inhibitor-1 4G/4G Gene Polymorphism.

Myocardial ischemia due to coronary artery disease is an extremely rare condition in childhood and adolescence. Absence of obvious serious risk factors remains a challenge to modern cardiology. We present the case of a 14-year-old boy who underwent quadruple-vessel coronary artery bypass grafting with bilateral pedicled internal mammary artery and bilateral radial artery grafting.

Neural Network Prediction of ICU Length of Stay Following Cardiac Surgery Based on Pre-Incision Variables.

Background: Advanced predictive analytical techniques are being increasingly applied to clinical risk assessment. This study compared a neural network model to several other models in predicting the length of stay (LOS) in the cardiac surgical intensive care unit (ICU) based on pre-incision patient characteristics.

Methods: Thirty six variables collected from 185 cardiac surgical patients were analyzed for contribution to ICU LOS.

Heterogeneity of TERT promoter mutations status in squamous cell carcinomas of different anatomical sites.

Squamous cell carcinoma (SCC) can arise from different anatomical sites including the skin, head and neck, lung, esophagus, genital area, and so on. Despite the same histopathologic features and immunohistochemistry profile, the SCCs of different body sites can show tremendous differences in their presenting symptoms, risk factor associations, natural history, prognosis, and response to treatment. This may reflect the fact that SCCs are heterogenous and likely have unique molecular characteristics at different anatomical sites.

Giant myxoma causing heart failure symptoms.

Background: Myxomas arising from the eustachian valve are exceedingly rare.

Case Report: A 72-year-old Jamaican-Chinese woman was evaluated for worsening dyspnea. The 2-dimensional and real time 3-dimensional transesophageal echocardiogram showed a 75 mm length × 44 mm width, multilobulated, mobile mass arising from the eustachian valve occupying the entire right atrial and right ventricular cavities extending into the coronary sinus, right ventricular outflow tract, and proximal inferior vena cava.

Magnevad status of design improvements human blood results and preliminary sheep trial.

Magnevad II is an improved version of Magnevad I and both are fourth-generation axial flow left ventricular assist devices. A major simplification has been implemented and tested. Magnevad I used a magnetically suspended rotor requiring active axial control.

Immediate structural valve deterioration of 27-mm Carpentier-Edwards aortic pericardial bioprosthesis.

We describe two cases of immediate structural valve deterioration of the 27-mm Carpentier-Edwards pericardial valve. Tissue characteristics of bovine pericardium and the possible mechanism of failure are discussed.

Open pulmonary embolectomy for treatment of major pulmonary embolism.

Background: Inadequate data exist regarding the management of acute major pulmonary embolism. Various modalities that are used, including thrombolytics and embolectomy, have not been shown to conclusively improve mortality when compared to heparin. In the past, open pulmonary embolectomy was reserved for patients with severe hemodynamic instability because of its high mortality rate.

Atherosclerotic pseudoaneurysm of the ascending aorta.

Pseudoaneurysms in the ascending aorta most commonly occur as a complication of surgical procedures at this site. They have also been reported in association with trauma, infection, aortitis, and other disorders. Pseudoaneurysm formation in the descending aorta or arch may occur as a result of penetrating ulcers in the presence of severe atherosclerotic plaque.

Recurrence of renal cell carcinoma with extensive vena caval thrombus three years after radical nephrectomy.

A 70-year-old man, who had undergone a radical nephrectomy for localized renal cell carcinoma (RCC) three years ago, was recently evaluated for shortness of breath. During his work-up, a transesophageal echocardiogram and magnetic resonance imaging indicated an extensive vena caval thrombus originating from the renal vein stump. Successful vena caval thrombectomy with cardiopulmonary bypass confirmed that the thrombus was comprised of RCC.
