The current role of surgery in treating adult patients with patent ductus arteriosus.

Objective: Surgical closure of patent ductus arteriosus (PDA) is still required in selected adult patients. We analyzed the morphology of the anomaly and coexisting pathological findings in adult patients who were recently referred to our institute for surgical PDA repair.

Patients And Interventions: Six adult PDA patients who were not considered candidates for percutaneous closure underwent surgical PDA correction.

[Treatment of defects of soft tissue and sternum, as postoperative complications of A-C bypass, case report].

Medial sternotomy is optimal approach for great number of heart surgery. Deep infection of sternum and mediastinis are very rear, but very dangerous complications followed by high rate of morbidity and mortality. Factors which can be responsible for these complications are numerous: post operation bleedings, surgery reinterventions, extended mechanical ventilation, liver chronic diseases, older age, diabetes, previous irradiation therapy, respiratory obstructions and use of steroids.

[The calcified ascending aorta in aortocoronary bypass].

Heavily calcified ascending aorta significantly increased morbidity and lethality during open-heart surgery. Cannulation and clamping (partial or total) of severely atherosclerotic ascending aorta can easily cause damage and rupture of aortic wall, with consequential distal (often fatal) embolization with atheromatous debris (brain, myocardium). From June 1998.

[Perioperative myocardial failure and mechanical cardiac support --a five year experience].

Inability to wean a patient from the cardiopulmonary bypass after open heart procedure is reality of the clinical practice. The only realistic chance for these patients is some form of mechanical circulatory support. Over the period from November 1988 to November 1993, in 17 patients the roller-pump mechanical assist device was inserted, i.

An ex vivo model for the reperfusion of explanted human hearts.

A model of an ex vivo-reperfused human heart was developed by using a modified Langendorff coronary perfusion circuit. The technical and physiologic aspects of reestablishing myocardial contractility are described. Preliminary studies were conducted in animals.
