[Valvular replacement in florid endocarditis. Report on 5 cases].

This is an account of experience with valve replacement in patients with active endocarditis. In four patients the aortic valve was replaced, and in one, the mitral valve. Indication for surgery in all five cases was heart insufficiency. Two patients died, one of acute left heart failure five weeks postoperatively, and one of brain embolus in the presence of persisting acute endocarditis, four months postoperatively. Covered in the discussion are other indications for valve replacement in the presence of acute endocarditis, namely, serial emboli, fungus endocarditis, resistance to and toxic reactions of antibiotics, and mycotic sinus of valsava aneurysm. In conclusion, results obtained by other authors are reported.

[Acute left heart failure following repair of atrial septal defects. Its treatment by reopening].

Among 716 patients operated on for an ASD, 15 of them, following closure of the defect, developed acute left heart failure requiring partial re-opening. The most prominent anatomical finding in these cases was hypoplasia of the left ventricle. Also remarkable in some patients was severe pulmonary hypertension, which may have led to right ventricular hypertrophy. Therefore, a marked difference of the stroke work of the left and right ventricle, respectively, appeared to be the essential underlying hemodynamic mechanism. The prognosis has been found to depend mainly on prompt surgical intervention; so in all poor-risk cases continued monitoring of left atrial pressure is indicated for early detection of impending left heart failure.--The high incidence of left heart failure as cause of death after repair of an ASD indicates the importance of this complication.

[The fate of the pulmonary hypertension after ASD-closure in adults (author's transl)].

10 female and 7 male patients, who were operated for secundum type Atrial Septal Defect with Pulmonary Hypertension, got postoperative check-ups including right heart catheterisations. The investigations were performed on the average 6.6 years postoperatively. There was a fall of the systolic pulmonary pressure and of the flow; pulmonary resistance fell in 8 cases and rose in 9. The low left ventricular cardiac index together with an elevated left atrial pressure may be the pathogenetic cause of postoperatively elevated pulmonary resistance.

Innominate artery enlargement in congenital arteriovenous fistula with subsequent tracheal compression and stridor.

To demonstrate that airway obstruction may be the first manifestation of a congenital fistula, a female newborn is reported who presented with increasing stridor during her first 23 months of life. Magnetic resonance imaging and Doppler echocardiography revealed an enlarged innominate artery with turbulent flow. Angiography demonstrated an arteriovenous fistula between the right subclavian artery and right subclavian vein and an abnormal origin of the right internal thoracic artery. Bronchoscopy showed a pulsating compression of the middle section of the trachea. Closure and division of the fistula and aortotruncopexy were performed. The stridor disappeared, and there was marked relief of the tracheal obstruction, confirmed by bronchoscopy. It is concluded that, a search for enlarged vessels is necessary in cases of airway obstruction.

Evaluation of definitions and parameters for sepsis assessment in patients after cardiac surgery.

In 110 patients undergoing elective heart surgery on extracorporeal circulation, various parameters were studied regarding the early assessment of septic complications. In a first step, the Elebute score definition for postoperative sepsis validated in general surgery patients (score > or = 12) could be confirmed in an extended form (> or = 12 on > or = 2 days) for cardiac surgery patients. According to this definition (overall classification accuracy for clinically defined sepsis-related mortality: 94%), septic complications occurred in 16 patients and were associated with a significantly worse prognosis than in non-septic patients (mortality 69% vs. 1%, p < 0.0001). In contrast, SIRS (best classification criterion: positive on > or = 3 days) displayed a lower specificity for clinically defined sepsis-related mortality, at least during the early postoperative course (accuracy: 67%). Based on the Elebute score classification, other more practicable parameters were investigated regarding their usefulness for an early sepsis risk assessment in post cardiac surgical patients. Five additional severity scores (APACHE II, MOF-Goris, HIS, SAPS, SSS) were comparable (ROC area: 0.94 to 0.96) and superior to plasma PMN-elastase and neopterin, haemodynamics and clinical parameters in predicting the risk for septic complications as early as by the first postoperative day.

One heart transplanted successfully twice.

We report the first successful reuse of a previously transplanted heart after perioperative brain death of the first recipient. The second recipient was a 66-year-old man suffering from end-stage ischemic cardiomyopathy. The intra- and postoperative course of the retransplantation was completely uneventful. At the time of writing, more than 2 years after reuse of the graft, the patient remains in New York Heart Association class I. This procedure, which proved to be possible under certain optimal conditions, should be considered in the case of brain death of a graft recipient, particularly with regard to the ongoing donor shortage.
