[Recurrences after surgical treatment of achalasia of the cardia (author's transl)].

We observed 17 cases of so-called recurrences of achalasia of the cardia (10 times after preceding dilatation and 7 times after Heller's operation). For surgical treatment 16 of these patients underwent cardiomyotomy, using the transthoracic approach. In one patient who had cardiomyotomy plus fundoplication at the first operation an oesophago-gastrostomy became necessary. Three quarter of these patients had a satisfactory result when followed up. I case of recurrence the authors recommend to give priority to cardiomyotomy, rather than to dilatation or bougienage.

[Upper gastrointestinal tract hemorrhages following heart surgery].

The clinical histories of 612 patients who underwent an operation of the heart were evaluated. Eight times a more severe haemorrhage from the upper gastrointestinal tract was described, i.e. 1.3%. One patient died under the signs of the septic shock. All patients were treated conservatively, only in one patient an ulcer existed 12 years before the heart operation.

[General surgery following heart valve replacement (author's transl)].

Patients with heart valve replacement regarding further surgical treatment are sub-divided into 3 groups. 1) Patients after open or closed reconstruction of valves with sinus rhythm and no anticoagulation.--2) Arrhythmic patient of the same kind but under anticoagulation.--3) Patients with valve replacement, who are under anticoagulation if there is no vital contraindication.--Group 1 and 2 may be operated on at every general hospital, provided cardiological supervision can be practiced. Until now patients of group 3 should always be treated in a cardiosurgical centre.

[Indication for alloplastic heart valve prosthesis].

The indication for the alloplastic substitution of the cardiac valve results from the expectation of life with natural course of the disease on the one hand and with the operative risk and late results on the other. For the diagnosis of heart diseases intracardial methods are necessary in much cases. Contraindications result from heavy myocardial and coronary changes which increase the operative risk considerably and no postoperative improvement is to be expected. In the low-pressure system the implantation of artificial cardiac valves is used cautiously and plastic methods are preferred.

[Studies on blood traumatization following heart-valve prosthesis].

In 47 patients blood traumatisation was checked after interventions on cardiac valves. The cases in question were: 34 implantations of valve prostheses, 10 valve reconstructions and 3 re-operations because of paravalvular leakages. The tested valve prostheses according to Starr-Edwards, Björk-Shiley and Beall revealed subclinical haemolyses of various degrees. In aortic position the values for Björk-Shirley prostheses showed advantages as compared to the Starr-Edwards valve. Of all tested valve types the Beall prostheses caused the highest blood traumatisation. Manifest haemolytic anaemia was found only in 3 cases, two of them showing paravalvular leakage. In the cases of double valve replacement performed with combined Starr-Edwards and Beall prostheses the haemolysis was only slightly higher than in cases of mitral valve replacement with Beall valves only. In three cases with paravalvular leakage the parameters of haemolysis increased very much, returning to normal in 2 patients after successful correction. The assessment of the parameters of blood traumatisation is indispensible for the choice and improvement of the different types of valves and essential for the diagnosis of paravalvular leakage as well as for the control after leakage repair.

[Blood traumatization after heart valve replacement (author's transl)].

Blood traumatization after heart valve reconstruction or replacement was checked in 47 patients. Among the types of prostheses tested the Beall-valve caused the highest subclinical hemolysis, the Björk-Shiley-valve the lowest. In the aortic position the values for the Björk-valve were better than those for the Starr-valve. In cases with double valve replacement (Starr in aortic, Beall in mitral position) hemolysis was not much higher than in cases with single Beall mitral valve replacement. Clinical hemolytic anemia was only observed in 3 patients, 2 of them being affected with paravalvular leakage. In cases of paravalvular leakage parameters of hemolysis was very high and became normalized after successful repair in 2 patients.

[Hazards in the operative treatment of Ductus Botallo (author's transl)].

Possible errors and risks in operations of the ductus Botallo are discussed by using the experience from 282 operations. In young patients and adults the operative closure has to be decided upon according to the degree of the pulmonary vascular resistance. In newborns the closure of the ductus should be performed when symptoms such as heart insufficiency, frequent pneumonias and cyanosis are present. Haemorrhage due to damage of the walls is most frequent intraoperative complication. The procedure of controlling is dealt with more in detail. At least possibilities to treat the so called recanalisation or pseudorecidive are discussed. No patient was lost by intraoperative complications. The total mortality amounted to 1.4 per cent.

[Experimental and clinical use of the mini-size bubble-bag thermooxygenator by the Rygg-Kyvsgaard method].

The authors report on experimental and clinical use of the Mini-size-bubble-bag-thermooxygenator according to Rygg-Kyvsgaard. The advantages and possible applications are demonstrated. The Mini-size-bubble-bag-thermooxygenator is recommended for routine cardiosurgery on infants. The authors point at possibilities to use it in systems of extracorporeal circulation beyond cardiac surgery.

[Experiences from early detection and surgical treatment of mediastinal neoplasms (author's transl)].

87 mediastinal tumors were operated at the Halle Universitätsklinik between 1951-1973. 42.5% were diagnosed occasionally by the yearly X-ray mass screening. 47.5% were benign, 34.4% malignant. The lower proportion of malignancies is attributed to the rapid growth of the tumor and the long interval between the screenings (1 year). Results, localizations and treatment are reported.
