Late surgical repair of ventricular septal defect due to nonpenetrating chest trauma: review and report of two contrasting cases.

Traumatic rupture of the interventricular septum is a rare condition usually presenting in infancy and childhood. This report describes two cases: a 3-year-old boy operated on soon after the diagnosis was made, and a 15-year-old girl operated on 12 years following the causative accident. Both patients had the diagnosis confirmed by cardiac catheterization. The typical appearance of a traumatic ventricular septal defect (VSD) was seen during surgical repair that was successfully carried out in both patients. The protracted clinical course of the second patient, eventually requiring corrective intervention, contributes to the understanding of natural history of traumatic VSD.

Nonfunctioning paraganglioma of the posterior mediastinum (case report)

A case of nonfunctioning paraganglioma of the posterior mediastinum in a 20-year-old white man is presented. The diagnosis of aorticosympathetic paraganglioma (Glenner-Grimley classification) was established by histologic examination after surgical removal of the tumor.

Plastia valvar aórtica por ampliação de válvula com pericárdio bovino: nota prévia

A new technique for correction of aortic incompetence by the advancement of one more valve leaflets with bovine pericardial is presented. After experimental studies in isolated animal hearts this technique was used with success in one patient.

Experiência com dois tipos de técnicas para o tratamento cirúrgico da insuficiência mitral: I. Prótese com preservação de elementos do sistema valvar. II. Plastia valvar com reconstrução e avanço da cúspide posterior

The continuity between mitral valve and the left ventricular wall through chordae tendinae and papillary muscles plays a role in left ventricular function. The morbity and mortality for mitral valve replacement remain much higher than other cardiac procedures such as aortic valve replacement, mitral valvuloplasty and coronary artery bypass grafts. These facts justify all possible studies related to the correction of mitral valve insufficiency. The present paper presents our experience with two techniques for correction of mitral valve insufficiency: valve replacement with preservation of the mitral apparatus components and valvuloplasty by the reconstruction and advancement leaflet. Our main concern was the surgical details and ventricular function studies were not performed. Various techniques to maintain continuity of the mitral valve annulus and the ventricular musculature, when valve replacements is mandatory, are presented. The importance of the reconstruction and advancement of the posterior leaflet, alone or associated with other repair techniques such as comissurotomy, annuloplasty and shortening of chordae tendinae, is emphasized.
