A case of right ventricular assistance required after emergency heart transplantation is reported. The patient was a 62 year-old man with terminal congestive heart failure due to ischaemic cardiomyopathy. Preoperatively, this patient had a cardiac index of 1.93 1.min-1.m-2, moderate pulmonary hypertension (mean Ppa: 34 mmHg) and pulmonary arteriolar resistances at 440 dyn.s.cm-5; clinical examination revealed pulmonary oedema, cardiac liver and oliguria with renal failure. Cardio-pulmonary bypass lasted 145 min, including 50 min of assistance after graft reperfusion. Despite postoperative dopamine and dobutamine treatment, oliguria and central venous pressure increased, and higher doses of catecholamines (adrenaline, noradrenaline) and pulmonary intraarterial prostaglandin E1 infusions were required. Despite these agents and haemofiltration, mechanical assistance was needed and a centrifugal pump set up. Diuresis and haemodynamic parameters improved. The patient was weaned from this assistance after 102 h. A satisfactory haemodynamic status was then maintained, but still required 1.4 micrograms.kg-1.min-1 noradrenaline and 0.02 microgram.kg-1.min-1 prostaglandin E1. Six days later, the patient was weaned from the ventilator, but he rapidly developed fatal aspergillus septicaemia. This case demonstrates that temporary mechanical assistance can be useful for treating right ventricular failure occurring after transplantation.

Aorto-caval fistula (ACF) is a rare complication of abdominal aortic aneurysm. It occurs in 1-6% of cases. The classic diagnostic signs of an ACF (pulsatile abdominal mass with bruit and right ventricular failure) are present only in a half of the patients. The most common diagnostic imaging procedures like ultrasound and computed tomography often are not sufficient enough. This leads to the delay in diagnosis, which has a great impact on the results of operation. We report a case of a patient, who was treated before admission to the Clinic because of azotemia and oliguria suggesting renal failure.

The development of acute kidney injury in patients with pulmonary embolism (PE) has not been well documented. We report a patient who developed acute oliguria in the setting of massive PE. Catheter embolectomy followed by ultrafiltration resulted in an immediate and dramatic improvement in urine output. Uncharacteristically, serum creatinine did not rise during the oliguric phase for several days until after embolectomy, and there were no metabolic derangements. Our observation that embolectomy and ultrafiltration helped with hemodynamics and renal perfusion despite decreased cardiac output suggests that right ventricular failure from both pressure and volume overload may have been central to this process. We review the older and recent literature in support of our observations.

Cardiac amyloidosis may occur in any type of systemic amyloidosis. The clinical picture is often characterized by restrictive cardiomyopathy. We report the case of a 41-year-old female patient admitted to the Department of Cardiology with clinical signs of right heart failure: congested jugular veins, hepatomegaly, peripheral edema, ascites associated with atrial fibrillation, low values of arterial blood pressure and oliguria. Echocardiographic findings were helpful for the diagnosis of cardiac amyloidosis: enlarged atrial cavities, normal size ventricles, thickened ventricular septum and posterior left ventricle wall with normal left ventricular ejection fraction, mitral and tricuspid regurgitation. Two-dimensional echocardiography revealed additional features: thickened papillary muscles and a specific "granular sparkling" appearance of the thickened cardiac walls - probably due to the amyloid deposit. Gingival biopsy showing amorphous eosinophilic material located in the vessel walls and the specific dichroism and "apple-green" birefringence under polarized light on Congo red stained slides completed the diagnosis of systemic amyloidosis. We recommend cardiologists to take into account a possible cardiac amyloidosis in a patient with unexplained refractory heart failure and a typical pattern of restrictive cardiomyopathy revealed by echocardiographic examination. We also emphasize the fact that the complete diagnosis cannot be set without a biopsy that should reveal the presence of amyloid. Although endomyocardial biopsy, completed with histochemical and immunohistochemical stains, is a valuable diagnostic method, in cases with advanced cardiac failure, the best site for this biopsy may be the gingiva.
