[The isolated agenesis of a branch of the pulmonary artery. A case report: its diagnosis and therapy].

We illustrate a case of so-called right pulmonary artery agenesis, discovered in a 3-month-old baby. This kind of malformation is rarely reported in neonatal age being most often discovered in the adulthood. The patient presented with cardiac failure, cyanosis and radiological features of cardiomegaly and left side pulmonary venous congestion.

[Perfusion catheter and cardio-pulmonary support standby: organizational strategy for high risk PTCA. Description of a case treated successfully].

The organizational strategy used in a high risk Coronary Angioplasty procedure is discussed. The attempted vessel was a severely stenosed Right Coronary Artery in a patient who had undergone triple graft, with residual obstruction of Left Main Artery and only one patent venous graft on a marginal branch of the Circumflex artery. The procedure was performed using a Stack type autoperfusion balloon angioplasty catheter, with a Cardiopulmonary Support System held in standby.

[Persistence of the right venous sinus valve simulating a right atrial myxoma in a case of total anomalous pulmonary venous return. Echocardiographic, anatomo-clinical and surgical aspects].

A case of persistence of the right venous sinus valve that on echocardiographic examination simulated right atrial myxoma is reported in a patient with total abnormal pulmonary venous return in the coronary sinus. Echocardiography showed a mobile, pedunculated mass present in systole in the right atrium that shifted to diastole in the right ventricle, highly suggestive of right atrial myxoma. The right ventricle also showed a volume overload and a space without echoes behind the left atrium.

[Aortic insufficiency caused by valvular dysplasia in childhood. Apropos of 3 cases].

Three patients whose aortic incompetence (A.I.) was recognized in childhood, have had an angiographic study 10, 9 and 4 years, respectively, following the first clinical diagnosis of their valvular disease.

Double outlet right ventricle with atrioventricular discordance. Report on cases having situs solitus, dextrocardia, pulmonary stenosis and levomalposition of the aorta.

We describe six patients with situs solitus of viscera and atria, dextrocardia, atrioventricular discordance, ventricular septal defect, double outlet from the morphological right ventricle, pulmonic stenosis and levomalposition of the aorta. Four patients were male and two female; their age ranged from 3.5 to 31 years (mean 13.
