Atresia of the Coronary Sinus Ostium to the Right Atrium with a Persistent Left Superior Vena Cava International Journal of Morphology
Caetano,Abadio Gonçalves; Ribeiro,Tiago Coelho; Filho,Omar Andrade Rodrigues; Fazan,Valéria Paula Sassoli.
The coronary sinus has lately assumed an important role in the cardiologic clinic once it has been widely used in invasive procedures of the heart. Commonly, it is used during the electrodes implants for the epimiocardic monitoring of the cardiac rhythm, through a biventricular pace maker. These invasive procedures are not possible in hearts with an atresic coronary sinus ostium. In the presence of this anomaly, another may occur: the development of the "Marchal" vein which is a remaining of the left superior vena cava (LSVC). This happens so that the venous blood from the heart can drain into the right atrium, by a communication between the LSVC and the left brachiocephalic vein. The presence of a LSVC brings difficulties when performing an invasive...

Clinical applications of retrograde autologous priming in cardiopulmonary bypass in pediatric cardiac surgery BJMBR
Fu,G.W.; Nie,Y.F.; Jiao,Z.Y.; Zhao,W.Z..
Retrograde autologous priming (RAP) has been routinely applied in cardiac pediatric cardiopulmonary bypass (CPB). However, this technique is performed in pediatric patients weighing more than 20 kg, and research about its application in pediatric patients weighing less than 20 kg is still scarce. This study explored the clinical application of RAP in CPB in pediatric patients undergoing cardiac surgery. Sixty pediatric patients scheduled for cardiac surgery were randomly divided into control and experimental groups. The experimental group was treated with CPB using RAP, while the control group was treated with conventional CPB (priming with suspended red blood cells, plasma and albumin). The hematocrit (Hct) and lactate (Lac) levels at different...

Histidine-tryptophan-ketoglutarate solution decreases mortality and morbidity in high-risk patients with severe pulmonary arterial hypertension associated with complex congenital heart disease: an 11-year experience from a single institution BJMBR
Li,X.W.; Lin,Y.Z.; Lin,H.; Huang,J.B.; Tang,X.M.; Long,X.M.; Lu,W.J.; Wen,Z.K.; Liang,J.; Li,D.Y.; Zhao,X.F..
Cardioplegic reperfusion during a long term ischemic period interrupts cardiac surgery and also increases cellular edema due to repeated solution administration. We reviewed the clinical experiences on myocardial protection of a single perfusion with histidine-tryptophan-ketoglutarate (HTK) for high-risk patients with severe pulmonary arterial hypertension associated with complex congenital heart disease. This retrospective study included 101 high-risk patients undergoing arterial switch operation between March 2001 and July 2012. We divided the cohort into two groups: HTK group, myocardial protection was carried out with one single perfusion with HTK solution; and St group, myocardial protection with conventional St. Thomas' crystalloid cardioplegic...

Oral triiodothyronine for the prevention of thyroid hormone reduction in adult valvular cardiac surgery BJMBR
Magalhães,A.P.A.; Gus,M.; Silva,L.B.; Schaan,B.D..
Treatment of non-thyroidal illness by intravenous triiodothyronine (T3) after cardiac surgery causes a disproportional elevation of hormone levels. The administration of oral T3, which has never been studied in this context, could cause physiological hormone levels. The aim of this study was to test oral T3 for the prevention of T3 reduction during the postoperative period of valvular cardiac surgery in adults. Eighteen patients who underwent cardiac surgery for valvular disease with invasive hemodynamic monitoring were randomly assigned to 2 groups: the T group received oral T3 (N = 8), 25 µg three times/day, initiated 24 h before surgery and maintained for 48 h and the NT group (N = 10) received placebo. Serum T3, thyroxine and thyrotropin were...

Anomalous Origin of Left Internal Thoracic Artery from the Second Intercostal Artery International Journal of Morphology
Mehmet,O. C; Bahar,O. C; Pasaoglu,Ilhan.
Left internal thoracic artery (LITA) has increased importance and common use in coronary bypass grafting because of long-term better patency rate and improvement in both the duration and quality of survival of patients. LITA is a branch of the first part of the subclavian artery. We report a case in which the LITA originated from the second left intercostal artery. A 71-year-old man with a history of angina pectoris for 1 month was admitted to the hospital because of progressive increase in anginal symptoms. During the operation, it was noted that the LITA originated from the second intercostal artery. LITA used as a free graft. LITA was anastomosed to the left anterior descending coronary artery. He was free of symptoms 4 weeks after operation. To our...

Streptococcus bovis endocarditis: analysis of cases between 2005 and 2014 BJID
Mello,Renato; Santos,Marisa da Silva; Golebiosvki,Wilma; Weksler,Clara; Lamas,Cristiane.
Background: Streptococcus bovis is a classical etiology of endocarditis and is associated with colonic lesions. No series of cases from Brazil has been described. Objectives: To describe aspects of S. bovis endocarditis. Methods: This is a case series of patients admitted to a cardiac surgery referral center, during the years 2005-2014. Clinical, laboratory, echochardiographic, colonoscopic, treatment, surgical and outcome variables were studied. Results: Nine patients with S. bovis endocarditis were included; all cases fulfilled the modified Duke criteria. Incidence was 8/220 (4%) in years 2006-2014. There were seven male and two female patients; mean age was 56.7 years, standard deviation 13.4. All patients had native aortic valve involvement....

Asymptomatic and symptomatic embolic events in infective endocarditis: associated factors and clinical impact BJID
Monteiro,Thaíssa S.; Correia,Marcelo G.; Golebiovski,Wilma F.; Barbosa,Giovanna Ianini F.; Weksler,Clara; Lamas,Cristiane C..
ABSTRACT Background: Embolic complications of infective endocarditis are common. The impact of asymptomatic embolism is uncertain. Objectives: To determine the frequency of emboli due to IE and to identify events associated with embolism. Methods: Retrospective analysis of an endocarditis database, prospectively implemented, with a post hoc study driven by analysis of data on embolic events. Data was obtained from the International Collaboration Endocarditis case report forms and additional information on embolic events and imaging reports were obtained from the medical records. Variables associated with embolism were analyzed by the statistical software R version 3.1.0. Results: In the study period, 2006-2011, 136 episodes of definite infective...

Plasmatic ADAMTS-13 metalloprotease and von Willebrand factor in children with cyanotic congenital heart disease BJMBR
Soares,R.P.S.; Bydlowski,S.P.; Nascimento,N.M.; Thomaz,A.M.; Bastos,E.N.M.; Lopes,A.A..
Changes in plasma von Willebrand factor concentration (VWF:Ag) and ADAMTS-13 activity (the metalloprotease that cleaves VWF physiologically) have been reported in several cardiovascular disorders with prognostic implications. We therefore determined the level of these proteins in the plasma of children with cyanotic congenital heart disease (CCHD) undergoing surgical treatment. Forty-eight children were enrolled (age 0.83 to 7.58 years). Measurements were performed at baseline and 48 h after surgery. ELISA, collagen-binding assays and Western blotting were used to estimate antigenic and biological activities, and proteolysis of VWF multimers. Preoperatively, VWF:Ag and ADAMTS-13 activity were decreased (65 and 71% of normal levels considered as 113...
