Cystic atrioventricular node tumor excision by minimally invasive surgery
Full text linkCystic tumor in the atrioventricular (AV) node region is a rare cardiac primary tumor that can lead to sudden death. Our patient was a 43-year-old woman who presented with dyspnea and a first-degree AV block seen on electrocardiography. Echocardiography revealed a cystic mass attached to the inferior portion of the interatrial septum. After surgical excision of the mass, placement of a permanent pacemaker was required for complete heart blockage. Histopathologic examination revealed the mass to be a cystic tumor of the AV node region. To our knowledge, this is the first report of this condition diagnosed ante mortem and treated successfully with minimally invasive surgery. © 2013 by The Society of Thoracic Published by Elsevier Inc

Tetralogy of Fallot whit a "contralateral" ductus arteriosus
No full textTwo neonates were taken shortly after birth to our unit with a prenatal diagnosis of [S,D,S] Tetralogy of Fallot with pulmonary atresia and "unusual" aorta to pulmonary connection. The echocardiogram confirmed the main diagnosis showing: a left aortic arch with a vascular connection between the right innominate artery and the origin of the right pulmonary artery in patient A; and right aortic arch with a vascular connection between the left innominate artery and the origin of the left pulmonary artery in patient B
Aortopulmonary Collateral Artery from the Proximal Ascending Aorta: A Rare Anatomical Finding
No full textTetralogy of Fallot with pulmonary atresia and major aortopulmonary collateral arteries is a rare congenital heart lesion in which pulmonary blood supply may arise from different segments of the aorta. We report an unusual case of a newborn with a major collateral artery originating from the proximal ascending aorta. Successful reparative surgery was undertaken
Dacron Conduit for Extracardiac Total Cavopulmonary Anastomosis: A Word of Caution
No full textThe extracardiac conduit technique is a valid option for completing total cavopulmonary anastomosis (TCPC) in patients with a single ventricle. The technique allows for beating heart surgery, optimal flow dynamics, and reduced postoperative atrial arrhythmia. Different types of conduit have been proposed. This study reported a single-centre experience with two different types of conduit
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Can we make an early prediction of who will be discharged from the Intensive Care Unit the day after heart surgery?
No full textAbstract: Introduction: Most of the patients undergoing heart operation are discharged from the intensive care unit the
day after their operation. The aim of this study was to evaluate preoperative, intraoperative and early postoperative risk
factors for prolonged intensive care unit length of stay (intensive care unit stay greater than 1 day) in cardiac surgery
patients.
Materials and Methodology: This retrospective study examines the determinants of prolonged intensive care unit length of
stay in 2182 consecutive surgical patients. Univariate and multivariate analyses have been performed.
Results: 46.76% of all patients had a prolonged intensive care unit length of stay. Multivariate analysis revealed the
following independent predictors for prolonged intensive care unit length of stay: Preoperative: Age (p = 0.001), chronic
obstructive pulmonary disease (p = 0.049), serum creatinine (p = 0.003), serum total bilirubin (p = 0.048), chronic renal
failure requiring dialysis (P = 0.040), intravenous infusion of nitrates (p = 0.014), NYHA class 3 (p = 0.032), left
ventricular ejection fraction (p = 0.006). Intraoperative: aortic cross-clamping time (p = 0.04), CPB duration (P <
0.0001), lowest hematocrit on CPB (p < 0.0001), type of operation (p = 0.012), high doses of catecholamine therapy after
CPB (p = 0.001). Postoperative: re-exploration (p < 0.0001), massive transfusions (p < 0.0001), arterial pH at ICU
admission (p = 0.024).
Conclusion: Due to the increasing number of high-risk patients needing cardiac surgery, it is important to identify risk
factors for a prolonged intensive care unit length of stay. This can be applied for scheduling patients for cardiac surgery as
well as in optimizing intensive care unit resource planning when resources are limited.
