RESUMO
Endomyocardial biopsy (EMBx) is a useful tool for diagnosing various cardiac pathologies. However, the routine use of EMBx has not gained widespread acceptance due to the possible complications related to the EMBx. Thus, not much information is available on the complications related to the EMBx. We prospectively evaluated 90 consecutive patients who underwent 2-D echocardiography guided transfemoral right ventricular EMBx at Kyungpook National University Hospital between March 2002 and November 2005 to determine the incidence, nature and subsequent management of complications related to EMBx. The clinical diagnoses before the EMBx were arrhythmogenic right ventricular dysplasia in 54, dilated cardiomyopathy in 19, Brugada syndrome in 9, myocarditis in 6 and miscellaneous in 2 patients. The overall major complication rate was 5.6% and no procedure-related mortality occurred. Myocardial perforation (n=3), which was the most frequent complication, did not progress to cardiac tamponade requiring pericardiocentesis in any patient. Hemodynamically unstable ventricular tachycardia occurred in 1 patient. New and persistent right bundle branch block occurred in another. Our findings suggest that 2-D echocardiography guided transfemoral right ventricular EMBx is a relatively safe procedure.

BACKGROUND: Color M-mode doppler echocardiography has been suggested as a new noninvasive technique for assessing left ventricular diastolic function. The present study was performed to define the feasibility and value of color M-mode echocardiography for the assessment of left ventricular diastolic function in patients with acute coronary syndrome. METHODS: Thirty six patients with acute myocardial infarcion and twenty three patients with unstable angina were included (M/F=41/18, 61+/-12.2 years). Doppler study was performed using ATL HDI-3000 within 24 hours after the attack. In color M-mode study, ROP was measured with 'Front wave method' and 'Baseline shift method'. The patients were grouped into three groups based on E/A ratio and deceleration time (DT) in transmitral flow and S/D ratio in pulmonary venous flow; Group I=Normal pattern (E/A>1, S/D>1, DT>140 ms), Group II=Impaired relaxation pattern (E/A140 ms) and Group III=Pseudonormal/Restrictive pattern (E/A>1.5, S/D0.05). CONCLUSION: The ROP seems not to reflect the diastolic function in acute coronary syndrome, although it is measurable with the 'Front wave method' in most cases. The measurement of the ROP with 'Baseline shift method' is not feasible in the patients with acute coronary syndrome.
