Postmortal coronarography by means of a roentgen double contrast method

Zeitschrift für Kardiologie

Abstract

In the conventional postmortem coronary angiogram and vessels are illustrated by a "compact" filling with contrast medium. In the case of the double contrast technique, a thin film of contrast medium is brought about the inner surface of the arteries. Gas injected under controlled pressures into the vessels acts as a further control against the surrounding media. The method is suitable for a more precise illustration of the subepicardial and large intramural coronary arteries. Of particular advantage is the high transparency of the x-ray pictures and the possibility to make the coronary ostia visible. The evaluation of x-ray pictures produced at different controlled pressures permits conclusions about pressure-volume relations of defined vessel sections, which then can be analysed histologically.

Atrial Filbrillation

Atrial fibrillation refers to the abnormal heart rhythm characterized by rapid and irregular beating of the atria. Here is the latest research.

Atrial Fibrillation

Atrial fibrillation is a common arrhythmia that is associated with substantial morbidity and mortality, particularly due to stroke and thromboembolism. Here is the latest research.

Arrhythmia

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.

Bradyarrhythmias

Bradyarrhythmias are slow heart rates. Symptoms may include syncope, dizziness, fatigure, shortness of breath, and chest pains. Find the latest research on bradyarrhythmias here.
