Comparative StudyMid term course after pediatric right ventricular outflow tract reconstruction: a comparison of homografts, porcine xenografts and Contegras.
Homografts and porcine xenografts are valved conduits for pediatric RVOT reconstruction. They lack availability and durability. The Contegra, a glutaraldehyde fixed bovine jugular vein, was developed as an alternative. In this article, we compare single center results of 190 RVOT conduit implantations. ⋯ After 12 years RVOT reconstruction with 190 valved conduits, Contegras remain our device of choice. At 4 years, they show no subvalvular or valvular reason for explantation or reoperation. Contegras have the advantages of easy handling and availability, and they compare well with homografts regarding freedom from explantation and freedom from reoperation.

Congenital lung malformations--antenatal and postnatal evaluation and management.
We reviewed our institutional experience with pulmonary resection for congenital bronchopulmonary malformations and analysed the management and outcome of pregnancies with a prenatal diagnosis of congenital lung malformations. Between January 1993 and December 2003, 31 patients underwent evaluation and pulmonary resection for bronchopulmonary malformations. Common clinical presentations were respiratory distress (9), respiratory infections/pneumonias (22), and dyspnoea (9). ⋯ The presence of mass effects is an indication for therapeutic decompression. The risk of pulmonary compression, infection and malignant degeneration makes resection imperative, even in asymptomatic patients. Lobectomy is the procedure of choice, is well tolerated, and leads to excellent outcomes.

A simple implement [malleable endotracheal tube stylet] to aid positioning of chest drains.
Using a malleable endotracheal tube stylet to shape the chest drain during insertion helps in positioning them in the desired part of the pleural cavity.

'Tamponade' following cardiac surgery: terminology and echocardiography may both mislead.
Echocardiography is widely considered the gold standard for the diagnosis of tamponade. While a relatively common complication of cardiac surgery in adults, determining whether haemodynamics are compromised by a pericardial collection early post-operatively can be difficult. The aim of the current study was to determine the nature and magnitude of the diagnostic challenge posed by cardiac tamponade following cardiac surgery. We therefore examined the accuracy of echocardiography in the diagnosis of tamponade in this patient group. ⋯ Haemodynamically significant pericardial collections occurring early following cardiac surgery rarely cause classical clinical or echocardiographic features of tamponade. Recognition of this as a separate diagnostic entity is necessary to ensure appropriate surgical intervention is not delayed.

In highly developed nations, valve surgery will be increasing applied in older people, with more co-morbidities and a higher incidence of concomitant coronary artery disease. Valve surgeons will be facing increased competition from the catheter-based procedures, both for valve repair and replacement; these are already applied clinically, and their numbers will rise in near future. Early mortality in double valve procedures and in combined CABG and valve operations remains substantial, and there is ample room for improvement of surgical results. ⋯ Tissue-engineered valves are being developed, but are not ready for larger clinical trials. Cardiac surgery is undergoing a rapid transformation; radical changes both in scope and workload of cardiosurgical units in Europe can be expected in near future. Socio-economic factors and recent advances in medical technology contribute to these changes.
