Coronary dominance patterns in hypoplastic left heart syndrome.

Introduction: Although hypoplastic left heart syndrome (HLHS) be extensively studied, this disease still has a high mortality rate compared to other diseases treated as univentricular physiology. In this way, morphological differences between phenotypes within the spectrum of HLHS may be risk factors and their identification can assist in choosing treatment between subgroups.

Objective: To identify the most prevalent form of coronary artery dominance in hearts with HLHS groups with mitral atresia (MA) and mitral stenosis (MS).

Surgical treatment of patent ductus arteriosus in adults.

Objective: To analyze 34 patients submitted to surgical treatment of patent arterial duct with age beyond 18 years old.

Methods: Retrospective data collected from patient's charts with more than eighteen years old, submitted to surgical correction of patent arterial duct between 1997 and 2008 at Instituto do Coração da Faculdade de Medicina da Universidade de São Paulo.

Results: The mean age was 28.

Early extubation in the operating room in children after cardiac heart surgery.

Introduction: Early extubation is related to short length of hospitalization and less complications.

Objective: Data analysis from children extubated in the surgical room after cardiac surgery with ECC.

Methods: Retrospective data analysis.

Coronary dominance patterns in the human heart investigated by corrosion casting.

Objectives: The aim of this work was to analyze the dominance patterns of the circulation of the human heart, the number of branches from the right coronary artery to the left ventricle, the number of branches from the left coronary artery to the right ventricle and the frequency and location of intercoronary anastomoses.

Methods: Casts were made of 25 hearts by the injection of colored acrylic resin and subsequent corrosion using hydrochloric acid at the experimental surgery laboratory of Furb. Specimens with lesions or scars were discarded.

Outcomes of aortic coarctation surgical treatment in adults.

Objective: The aim of this study is to describe our experience in aortic coarctation surgery in adult patients by assessing the immediate and mid-term outcomes.

Methods: From January 1987 to March 2000, 50 consecutive adult patients underwent surgery for correction of aortic coarctation, through left lateral thoracotomy. Of these, forty two (84%) patients presented high blood pressure, with mean systolic arterial pressure of 170.

Vascular ring related to Kommerell diverticula: case report.

Report of a surgical treatment for vascular ring (right aortic arch and the anomalous origin of the left subclavian artery) related to Kommerell diverticulum with resection of the ligamentum arteriosum (ductus arteriosus), suture of the Kommerell diverticulum, and reimplantation of left subclavian artery in the ipsilateral carotid artery through left thoracotomy in a 13-year-old female.
