A Papillary Fibroelastoma of the Tricuspid Valve

Primary cardiac tumours are rare in children. Of these, papillary fibroelastomas are unusual but benign, usually being found in adults. There are only sporadic cases reported in children. We diagnosed such a papillary fibroelastoma involving the tricuspid valve in an asymptomatic child during a routine cardiac investigation.

Tratamento Cirúrgico dos Defeitos do Septo Auriculo-Ventricular. Experiência Uni-Institucional

OBJECTIVES: Atrio-ventricular septal (AVSD) defects include a variable spectrum of congenital malformations with different forms of clinical presentation. We report the surgical results, from a single institution, with this type of congenital cardiac malformation. Patients with hypoplasia of one of the ventricles were excluded from this analysis. POPULATION: Between November of 1998 and June of 2005, 49 patients with AVSD were operated on by the same team and in the same department. The average age was 37.3 months (medium 6 months) and 31 patients were female. In 38 patients (78%) an inter-ventricular communication was present (AVSD-complete) and of these, 26 were of the type A of Rastelli, being 13 of type B or C. The age for defect correction of the complete form was of 5.5 months, palliative surgery was not carried out on any of the patients. Associated lesions included: Down's syndrome in 22 patients (45%), patent arterial duct in 17 patients (35%), severe AV regurgitation in 4 patients (8%), tetralogy of Fallot in two (4%) and sub-aortic stenosis in one patient (2%). Pre-operatively 10 patients presented severe congestive heart failure and two were mechanically ventilated. RESULTS: Complete biventricular correction was carried out in all patients. The average time on bypass (ECC) was 74.1+/-17.5 min. and time of aortic clamping was 52.0+/-12.9 min. The complete defects were corrected by the double patch technique, and in all patients the mitral cleft was closed, except in two with single papillary muscle. There was no intra-operative mortality, but hospital mortality was 8%(4 patients), due to pulmonary hypertension crises, in the first 15 post-operative days. The mean ventilation time was of 36.5+/-93 hours (medium 7 h) and the average ICU stay was of 4.3+/-4.8 days (medium 3 days). The minimum follow-up period is 1 month and the maximum is 84 months (medium 29.5 months), during which time 4 re-operations (8%) took place: two for residual VSD's and two for mitral regurgitation. There was no mortality at re-do surgery. At follow up there was residual mitral regurgitation, mild in 17 patients and moderate in two. Four other patients presented with minor residual defects. CONCLUSIONS: The complete correction of AVSD can be carried out with acceptable results, in a varied spectrum of anatomic forms and of clinical severity. Despite the age of correction, for the complete forms, predominantly below 12 months, pulmonary hypertension was the constant cause for post operative mortality. Earlier timing of surgery and stricter peri-operative control might still improve results.

Case Report of Malignant Endometrial Polyps

The aims of this retrospective review were to determine the frequency of malignant endometrial polyps diagnosed with ambulatory hysteroscopy in the Obstetrics/Gynaecology Department of HDE, Lisbon, between January 2001 and December 2005 and to characterize these cases according to risk factors, sonographic and endoscopic findings tumoral histology, and tumor stage.We found seven cases of malignant endometrial polyps in a total of 1333 polyps initially diagnosed: an incidence rate of 0. 53%. These seven patients had a mean age of 68 years (55–82 years), and all were postmenopausal, with five having one risk factor each for endometrial cancer. Metrorrhagia was present in six of the seven patients(85.7%). Ultrasonography was abnormal in all seven patients, with a mean endometrial thickness of 26 mm(range: 12–44 mm). The hysteroscopy images suggested malignancy in all cases. All except one patient had a single polyp. The polyps had volumes between 1.5 and 3 cm; two were removed completely and five were biopsed. The histological subtype was: mixed endometrioid/serous papillary or clear cell (2), adenocarcinoma with squamous differentiation (2), carcinosarcoma (2), and clear cell carcinoma (1). Malignancy inside polyps is rare, but diagnostic hysteroscopy with visual guided biopsies can identify these cases in the earlier stages. The risk factors are not different from those of other endometrial carcinomas, but the histological subtype seems to point to more aggressive cancers.
