The module Cardiac Catheter is used to document a cardiac catheter examination. This examination enables a better phenotyping of cardiomyopathies, an assessment of the degree of severity and of the prognosis.
The examinations ought to be performed according to DZHK-SOP-K-05 .
 

Examination details

Quality level

  • Level 1: The examination is performed in accordance with the guidelines of the medical associations.
  • Level 2: The examination is performed in accordance with the specifications of the DZHK SOP. Minimum requirements to ensure the quality of the implementation and the examiners are defined in the SOP.
  • Level 3: The examination is performed in accordance with the specifications of the DZHK SOP and certification of the examiners: Definition of intr-observer and interobserver-variability (standard of epidemiological studies).

Right heart catheterisation

Catheterization of the right side of the heart is performed in accordance with the relevant standards and the respective study protocol. Puncture of the right femoral vein is performed under aspiration approx. 2 cm medial to the arterial puncture site. The guide wire is introduced through the indwelling catheter into the cranial vein until the tip reaches the inferior vena cava. To widen the puncture channel, the 7 French dilatator is fully inserted and subsequently exchanged for the 7F multipurpose catheter (MPC). The MPC is positioned above the guide wire in the upper part of the superior vena cava. After removal of the guide wire, the venous oxygen saturation levels are taken.

Pump function

Assessment of left ventricular (pump)function is qualitative:
  • 1. Evaluation of wall motion abnormalities according to the nomenclature defined by Herman at al. (Herman et al.).
  • 2. The classification and evaluation of specific wall regions are to be documented according to the Coronary Artery Disease Reporting System of the AHA (Austen et al.).

Myokardial biopsy

Removal of endomyocardial biopsies is performed in accordance with the relevant standards and the respective study protocol. After the coronary angiography has been performed the arterial 4F sheath is exchanged for the 8F sheath. This is followed by retrograde catheterization of the aortic valve in 20° RAO projection and placement of a 7F guiding catheter in the left ventricle. Under fluoroscopy, the tip of the catheter is positioned in the target region. Contrast agent is injected to ensure adequate distance to the endomyocard and to avoid injuries of the papillary muscles. The biopsy forceps is inserted through the 7F guiding catheter and biopsies are collected from different parts of the left ventricle. Immediately after collection of the myocardial biopsy, transthoracic echocardiography is performed to exclude the presence of pericardial effusion.

Number of biopsies

The recommended number of biopsies depends on the clinical question under consideration and whether material is to be collected for the purpose of addressing research questions. The latter is only possible if an application for ethical approval exists. For the clinical clarification of, e.g. storage diseases, experience has shown that 1-2 samples are needed for histological analyses, 1 sample for immune-histological analysis and, where applicable, 1-3 samples for molecular biology questions. For questions related to inflammatory responses and/or virus identification, experience has shown that 6 additional samples are required. It is important to note that the quality/size of each biopsy obtained also determines the number of samples taken. We recommend to collect at least 5 samples per procedure and up to 10 to guarantee reliable results. Samples for histology and immunohistochemical analysis should be at least 1-2 mm in size.
