Complications of transvenous right ventricular endomyocardial biopsy in adult patients with cardiomyopathy: a seven-year survey of 546 consecutive diagnostic procedures in a tertiary referral center.

摘要: Abstract To determine the incidence, nature and subsequent management of complications occurring during right ventricular endomyocardial biopsy in patients with cardiomyopathy, all events 546 procedures 464 consecutive were prospectively recorded. The internal jugular vein was primary site introduction 96% cases. A total 33 (6%) occurred: 15 (2.7%) catheter insertion including 12 arterial punctures (2%), 2 vasovagal reactions (0.4%) 1 episode prolonged bleeding (0.2%), without sequelae; 18 (3.3%) included 6 arrhythmias (1.1%), 5 conduction abnormalities (1%), 4 possible perforations (0.7%) 3 definite (0.5%) (pericardial fluid). Two three a perforation died. There no secular trend complication rate, nor associated specific clinical or hemodynamic characteristics. It is concluded that overall rate low, but mortality may occur.
