Left atrial myxoma causing mitral insufficiency. Report of a case treated with mitral valve replacement.

A case of left atrial myxoma causing mitral insufficiency treated with valve replacement and diagnosed preoperatively as mitral stenosis is presented. The presence of mitral regurgitation is very rare in atrial myxomas and requires mitral valve replacement. In our case mitral regurgitaion was due to the mechanical trauma of the valve by the tumor mass because the patient had no history of rheumatic fever and the pathologic examination of the valve displayed neither rheumatic nor myxomatous degeneration.

Two-dimensional and Doppler echocardiography in the diagnosis of absent pulmonary valve syndrome (surgery without catheterization).

The majority of severely affected infants with absent pulmonary valve syndrome develop varying degrees of respiratory distress. Cardiac catheterization and angiocardiography are still performed in the diagnosis of these infants prior to surgery. However, considering the high risks of these invasive investigations for severely symptomatic infants, diagnosis using only noninvasive methods becomes important. In this regard, we present three cases of absent pulmonary valve syndrome, diagnosed pre-operatively by both two-dimensional and Doppler echocardiography. The diagnosis was confirmed by cardiac catheterization and angiocardiography in two cases and by surgery in a symptomatic infant. Therefore, we are of the opinion that the two-dimensional and Doppler echocardiographic methods are most reliable in diagnosing absent pulmonary valve syndrome, and that severely symptomatic infants can be referred for surgery without catheterization.

Two-dimensional and Doppler echocardiographic findings of congenital coronary artery fistula.

Three patients with coronary artery fistula confirmed by coronary angiography and surgery were studied using two-dimensional and Doppler echocardiography. Two of these patients had left coronary artery-right ventricle fistula. The proximal dilatation of the coronary arteries was visualized in all three patients by two-dimensional echocardiography. The course of the dilated right coronary artery and left circumflex artery was demonstrated by two-dimensional echocardiography in two patients. We were able to detect the disturbed flow at the drainage site in one patient by using the conventional Doppler echocardiography. In conclusion, it should be emphasized that two-dimensional and Doppler echocardiography can be useful methods in diagnosing coronary artery fistula.

Peripheral vein contrast echocardiography in atrial septal defect.

This study was carried out on 233 children suspected clinically of having atrial septal defect with the aim of investigating the diagnostic capability of peripheral venous contrast echocardiography. The transfer of contrast material from the right atrium into the left atrium was evaluated as "positive contrast", while noncontrast blood, passing from the left atrium into the right atrium was termed "negative contrast". Positive contrasts were quantitated in four grades. A significant negative contrast effect was graded 3- or 4-. Three positive, 4+ and/or 3-, 4- contrast effects were considered definite evidence of an atrial septal defect. Among the cases with the above findings 92 underwent surgical closure of atrial septal defect. The procedure was successful in all patients operated; the size of the defect was large. This result demonstrates that the method applied is a safe and reliable one. However, in a group of cases without the above echocardiographic findings the presence of an atrial septal defect was detected by cardiac catheterization and angiocardiography. Therefore, we can conclude that the method applied is not a sensitive, but a specific one, for definite detection of atrial septal defect.

Open mitral commissurotomies. Analysis of 100 cases.

Routine use of open mitral commissurotomy in all cases of rheumatic mistral stenosis is the recommended treatment of choice in recent years. Effective division of the subvalvular apparatus (chordae tendineae and papillary muscles) can be accomplished easily during open commissurotomy and therefore recurrences after the open approach is less than the recurrences after closed commissurotomy. These subvalvular elements can not be freed easily during closed mitral commissurotomy. Low mortality rates after open approach suggests that this operation can be performed safely in cases of MS. Open approach has several advantages versus closed commissurotomy. We believe that closed commissurotomy should be replaced by open commissurotomy in all cases of MS.

Aortic thrombosis in the newborn infant.

Two cases are reported in which thrombus was found in the aorta at postmortem. In one case the thrombus had originated within the ductus arteriosus. In the other case, the thrombus was associated with congenital heart disease and polycythaemia.

Congenital double-orifice mitral valve. A case report.

A three-year-old girl was admitted to Hacettepe Children's Hospital due to sweating and poor feeding. Echocardiography demonstrated ostium primum atrial septal defect with a cleft mitral valve. After two months of medical follow-up with digitalis, she was subjected to open-heart surgery, and a primum-type atrial septal defect with double mitral orifice was found. To avoid creating acute mitral stenosis, the cleft was only partially sutured and the septal defect was closed with a patch. Her postoperative recovery was uneventful. It is emphasized that surgical intervention should be individualized in each case.

Total correction for tetralogy of Fallot after Brock-type operation.

We present a case of tetralogy of Fallot who had previously undergone a graded Brock-type operation. The post-operative development of pulmonary arteries and pulmonary trunk after the Brock operation were very suitable for total correction, which was then performed successfully. In contrast to shunt, in Brock-type operations enlargement of the outflow tract induces symmetrical growth of hypoplastic pulmonary arteries without the risk of acquired pulmonary obstruction or peripheral stenosis at the site of anastomosis. After palliative operations, the repair can be deferred until the pulmonary arteries are of a suitable size.
