Successful percutaneous retrieval of a dislodged left atrial appendage occlusion device with double transseptal sheaths and biopsy bioptome
. Catheter Cardiovasc Interv 2015;85:328-31.
Right ventricular EMB was obtained using a flexible bioptome
(Westmed) via the right femoral vein .
The biopsy is done using fluoroscopic guidance via a right internal jugular vein approach with specimens obtained from inside the right ventricle using a long biopsy forcep or bioptome
. The procedure typically takes less than 20 minutes, enabling the recipient to get on with daily exercise and activities.
However, with the advent of long flexible bioptome, femoral approach can also be employed.
Finding it difficult to negotiate the bioptome through inferior vena cava, that is usually uncustomary, it was decided to use mullein sheath at first stance.
The characteristic features of HCM are often located deep within the septum and are inaccessible to the bioptome
. Hearts from individuals without HCM often have physiologic focal myocyte disarray at the junction of the posterior right ventricle and septum, which may lead to erroneous false-positive results by endomyocardial biopsy.
After angiographic exclusion of any coronary artery disease and other possible causes of LV dysfunction, EMBs from the right ventricular septum were obtained using a flexible bioptome
(Westmed, Germany) via the femoral vein approach .
At the end of the catheter is a bioptome
, a tiny instrument used to snip off a piece of tissue.
