Critical left ventricular outflow tract obstruction due to accessory mitral valve tissue.

Left ventricular outflow tract (LVOT) obstruction due to anomalous tissue tag arising from the mitral valve is a rare congenital cardiac anomaly. It generally becomes symptomatic during the first decade of life as exercise intolerance, chest pain, or syncope at effort. To date, only a few cases of critical systemic obstruction due to isolated mitral valve anomaly in neonates have been reported. We report the case of a neonate who was a few hours old and was referred in severe clinical condition due to critical left ventricular outflow obstruction resulting from an anomalous tissue tag of mitral valve origin.

[Late traumatic rupture of the chordae tendineae].

A rare case of traumatic rupture of chordae tendineae with tricuspid regurgitation is described. The rupture occurred later trauma, with an unusual mechanism, in fact it has been produced by the strangling of valvular apparatus. This strangling occurred because heart's displacement in left thorax trough a pleural-pericardial window caused by trauma.

Right pulmonary artery development after modified Blalock-Taussig shunt (MBTS) in infants with pulmonary atresia, VSD and confluent pulmonary arteries.

The ideal palliation for infants with pulmonary atresia, ventricular septal defect and confluent pulmonary arteries should promote normal development of the pulmonary artery branches. In 26 patients who survived a modified Blalock-Taussig shunt (MBTS) in the first year of life, the right pulmonary artery was measured before and after operation by two dimensional (2D) echocardiography. In each patient its size was compared to the normal value for the same body surface area. The patients were divided according to this ratio and according to the real size (mm). Although increased in all cases but two, the size of the right pulmonary artery remained remarkably less than normal in patients with an initially small right pulmonary artery. In view of these results, early palliative enlargement of the right ventricular outflow tract is probably advisable in infants with diminutive pulmonary arteries who do not show adequate pulmonary branch development after MBTS.

Exclusive double outlet right ventricle with atrioventricular concordance and pulmonary stenosis. Results of reconstructive surgery.

Double outlet right ventricle associated with atrioventricular concordance, pulmonary stenosis and situs solitus of the atria is a subset of double outlet right ventricle related through the surgical treatment. From 1974 to 1985, 14 patients, 5 males, 9 females (mean age 8.9 years, range 13 months-22 years) were operated upon. All patients had infundibular stenosis and normal or large pulmonary arteries. The apex of the heart was to the right in 2 patients, the right and left ventricles were superior and inferior in 2 patients and 1 patient had both anomalies. The ventricular septal defect was subaortic in 11 patients (aorto-mitral discontinuity in 5) and non-committed in 3 patients. Three patients had 2 ventricular septal defects. The aorta was anterior in 3 patients and to the right of the pulmonary artery in 11 patients. All patients, through a transventricular and transatrial approach, had a reconstructive surgery. In 3 patients, an aortic homograft valved conduit was used. One patient had the ventricular septal defect enlarged. There was one early death (7.1%) from high residual right ventricle pressure and no late death. One patient had a transient atrioventricular block. One patient was reoperated upon for a residual ventricular septal defect. All survivors had a good clinical result. Re-evaluation in 8 patients confirmed excellent haemodynamics: the right ventricle to pulmonary artery pressure gradient decreased from 80 mm Hg (range 60-95) preoperatively to 24 mm Hg (range 3-32) postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)

Pre-and postoperative Tc 99m scanning in monitoring pulmonary perfusion in the tetralogy of Fallot.

Angiocardiopneumographic scanning with Tc 99m was used in pulmonary perfusion and intracardiac shunt before and after radical corrective surgery of the tetralogy of Fallot. The study was carried out on 25 patients with the tetralogy of Fallot undergoing radical treatment with infundibular patch. Preoperative scanning has shown increased thickening of right ventricle and contemporary injection of pulmonary artery and aorta, the latter with a much higher radioactivity; the obstruction to the right flow was not clearly defined with respect to morphology and function, pulmonary perfusion has shown an extremely poor radioactivity and prolonged duration. Scanning following surgical treatment showed normal right and left phase and absence of residual shunts. Captation of marker in the lungs was always complete. Such data illustrate the many advantages gained by the use of non invasive diagnostic procedures in cardiology and "the first pass technique" in the evaluation of results of surgical treatment.

[Endoscopic retrograde catheterization of Vater's ampulla in the diagnosis of bilio-pancreatic diseases].

The technique, indications and contraindications for endoscopic retrograde cholangiopancreatography are discussed. Some of the most demonstrative cholangiographic and pancreatographic pictures are described and the reasons that have led to a marked reduction in complications immediately after the examination are analysed. Therapeutical aids for limiting any slight disturbances connected with the examination are also presented. Finally, some morphological data useful for differentiating between inflammatory and neoplastic lesions in the juxta- and intrapancreatic biliary excretory way and the pancreas itself are considered.
