[Campylobacter fetus endocarditis manifested by a popliteal mycotic aneurysm].

Background: Campylobacter fetus endocarditis is uncommon and may be life-threatening.

Case Report: A 91-year-old patient with rectal villous adenocarcinoma was admitted with fever and recent complaints of popliteal pain. The definite diagnosis of endocarditis and mycotic aneurysm related to C.

Nuclear magnetic resonance spectroscopy of excised human hearts.

Background: Phosphorus nuclear magnetic resonance spectroscopy has been proposed as a method of studying the metabolism of the myocardium in patients. Little is known about 31P nuclear magnetic resonance spectroscopy of diseased human hearts.

Methods: Two donor hearts meeting the requirements for heart transplantation and 11 diseased hearts were removed during a transplantation procedure and were studied in a horizontal 2.

[Cryosurgery in ventricular tachycardia. Value of myocardial hypothermia in the extension of thr depth of cryogenic lesions].

A desirable goal in surgery for ventricular tachycardia seems to be the development of a direct technique avoiding ventriculotomy, which has well-known harmful effects on the function of the left ventricle. This study is aimed at creating deep cryolesions, reaching to the subendocardial layers, on a closed ventricle. Forty-five cryolesions were performed with extracorporeal circulation in 15 piglets, applying a nitrogen protoxide tube (8 mm, -80 degrees C) on the left ventricle for two minutes.

[Atrial natriuretic factor after heart-lung transplantation. Consequences of cardiac denervation].

Due to the discovery and elaboration of alpha ANP, the heart can be considered a veritable endocrine gland involved in fluid and electrolyte homeostasis as well as blood pressure regulation. Nevertheless, the mechanisms regulating the synthesis and release of this new hormone are far from being understood. Heart-lung transplantation provides an interesting research model for evaluating the consequences of allograft denervation on alpha ANP synthesis and release, without the disadvantage of significantly increasing the overall atrial tissue mass, as observed in orthotopic heart transplantation.
