[Rupture of the ventricular septum following posterior wall infarction: echo- and Doppler echocardiography diagnosis with pressure determination].

In the postinfarct ventricular septal rupture, an early surgical intervention improves prognosis. A rapid and accurate diagnosis is necessary. A 56-year-old patient was admitted to the hospital with a Q-wave posterior myocardial infarction. Auscultation suggested a ventricular septal defect. Neither M-mode nor the two-dimensional echocardiography with apical four- chamber view could confirm the ventricular septal defect. Only the subcostal view showed a basal ventricular septal defect, which was sometimes covered by the septal leaflet of the tricuspid valve. With the continuous wave Doppler, a left-to-right shunt on the ventricular septum could be registered and the pressure in the right ventricle could be measured. Catheterization confirmed the diagnosis of a basal ventricular septal defect with the associated pressure characteristic. The basal ventricular septal defect was successfully closed with a patch. The high accuracy of the continuous-wave Doppler, which is superior to M-mode and two-dimensional echocardiography, was confirmed by this report. Pressure measurement in the right ventricle by continuous wave Doppler also provides a non-invasive diagnostic method that can be used at the bedside.

[Noninvasive assessment of an aortic bioprosthesis malfunction with Doppler echocardiography].

A 27-year-old patient with aortic stenosis received a Carpentier Edwards bioprosthesis and a reconstruction of the mitral valve, in 1978. With auscultation, M-mode and two-dimensional echocardiography, we diagnosed in 1985 a malfunction of the aortic prosthesis with restenosis, insufficiency and mitral insufficiency. A reliable qualitative and quantitative non-invasive assessment, however, was only possible with Doppler echocardiography. The velocity of blood flow over the aortic valve was measured with the continuous-wave Doppler technique; the aortic valve pressure gradient and the valve area were determined. The pulsed Doppler allowed a semi-quantitative evaluation of the severity of the aortic and mitral insufficiency. The intraoperative and pathological anatomical results confirmed the results from Doppler echocardiography: aortic valve prosthesis malfunction with restenosis and insufficiency and mild haemodynamically insignificant mitral valve insufficiency. The need for cardiac catheterization in patients with valvular heart disease and prosthesis is discussed.

[Long-term artificial respiration at home in restrictive ventilation disorders].

Combined chest wall and lung alterations may lead to severe restrictive respiratory disorder. In advanced cases with hypercapnia, hypoxemia and oxygen intolerance during spontaneous breathing, there are almost insuperable therapeutic difficulties. Three of such patients have been treated, after tracheostomy, at home for 60, 34 and 22 months respectively by intermittent IPPV ventilation. With an improved quality of life all these patients survived up to now. This result seems to be encouraging.

[Papillary fibroelastoma of the aortic valve. Sudden death caused by an uncommon tumor of the heart].

We describe a very rare tumor of the heart with a pendulous papillary fibroelastoma of the aortic valve, obstructing the ostium of the LCA - resulting in the sudden death of a healthy 40-year-old man. Acute severe ischemia was registered in the ECG a few minutes before death - corresponding especially to the myocardial regions perfused by the LCA. There is no doubt from the post mortem findings that the sudden death of this patient was caused by occlusion of the left coronary ostium by the pendulous papillary fibroelastoma.

[Scintigraphy of the myocardium. Comparative study between thallium and perfusion scintigrams (author's transl)].

In a total of 51 patients (26 with coronary heart diseases, 25 with primary myocardial diseases), the myocardial scintigrams after intracoronary particle injection (perfusion scintigraphy) and after intravenous nuclide injection with accumulation in the myocardium (thallium scintigraphy) were compared with each other and set against the coronary angiographic and levocardiographic findings. It was shown that extensive myocardial failures (aneurysms) can be represented by both nuclear medical procedures, but that perfusion scintigraphy is more sensitive and correlates more closely to the levocardiogram findings. Smaller abnormalities of contraction of the left ventricle (hypokinetic and akinetic areas) were always shown in the perfusion scintigram, more seldom in the thallium scintigram. The outstanding advantage of thallium scintigraphy is that it is non-invasive, it can be repeated as often as desired and is easily performed during ergometric stress.
