[Percutaneous occlusion by a detachable balloon of a fistula between the left coronary and the pulmonary artery].

A large fistula between the left circumflex coronary artery and the distal branches of the right pulmonary artery resulting in myocardial ischemia in a 52 year old woman with no angiographic atheromatous coronary lesions, was occluded by a detachable balloon introduced percutaneously and positioned at the origin of the fistula. A control angiogram performed one month later showed the balloon in position and the disappearance of the fistula. The Thallium myocardial scintigraphic abnormalities regressed after occlusion of the fistula. This is the second case (the first one in France) of radical non-surgical treatment of a congenital coronary fistula.

[Exudative enteropathy and residual tricuspid insufficiency following repair of tetralogy of Fallot. Regression following tricuspid valvuloplasty].

Chronic right ventricular failure was observed in a young female operated at 25 years of age for Fallot's tetralogy despite surgical refixation of the patch closing the ventricular septal defect which had previously worked loose. The signs of right ventricular failure were due to severe tricuspid incompetence, confirmed at catheterisation and selective right ventricular angiography. They were associated with major hypoproteinaemia which was not due to urinary loss nor hepatic dysfunction, but which was attributed to an exudative enteropathy. The correction of the valvular defect by valvuloplasty was followed by rapid correction of the biological abnormality. The authors review the relationship between serum proteins and cardiac disease, discuss those cardiac affections with known associations with exudative enteropathy, and also the possibilities of reversing the biological abnormality after surgical cure of the causal cardiac lesion.

[Corrected transposition of the great vessels with stenosis of the left atrioventricular valve in a 40-year-old woman].

The authors reports the detection of a rare and remarkably well tolerated cardiac malformation in a 40 year old woman whose clinical presentation would have suggested an ordinary mitral stenosis, had there not been a number of very unusual signs. Cardiac catheterisation and angiography showed a corrected transposition of the great arteries with stenosis of the systemic atrioventricular valve. This case is used to illustrate the principal malformations observed in association with corrected transposition of the great arteries, especially the common and very variable abnormalities of the systemic atrioventricular valve. The unusual feature of the reported case was the stenotic nature of the valvular lesion and the fact that this was the only associated intracardiac abnormality, simulating, at first sight, a rheumatic mitral stenosis.

[Hypoplasia of the right ventricle and cyanosis due to left-right atrial shunt within the framework of Turner's syndrome. Surgical closing of the interatrial connection after occlusion testing with balloon catheterization].

The authors describe the unusual cardiac malformation in a young girl with Turner's syndrome: right ventricular hypoplasia and atrial septal defect, resulting in central cyanosis. A trial of temporary occlusion of the atrial septal defect at cardiac catheterisation before surgical closure suppressed the right-to-left shunt and the cyanosis without significantly changing the hemodynamic parameters. The authors review the types of cardiovascular abnormalities associated with Turner's syndrome and emphasize the value of a temporary occlusion test of defects in certain cyanotic cardiac malformations with atrial right-to-left shunts; it may lead to a relatively simple surgical procedure, as in the case described.

[Pseudoventricular tachycardia linked to a reciprocal antidromic rhythm from Mahaim's fibers].

A 24 year old female presented with paroxysmal pseudo-ventricular tachycardia with wide QRS complexes and complete atrioventricular dissociation. Electrophysiological studies showed a junctional tachycardia with an antidromic reciprocating rhythm. The activation involved Mahaïm nodo-ventricular fibres in the anterograde direction, the nodo-hisian pathway being the retrograde limb of the reentry pathway. The main point of interest of this case was the presence of complete atrioventricular dissociation during tachycardia, the atria remaining in sinus rhythm with the possibility of sinus capture formally excluding the diagnosis of a paraseptal Kent bundle. This reentry mechanism has been previously described and constitutes a differential diagnosis of ventricular tachycardia.
