Triphasic Mitral Inflow Pattern in a Patient with Congenital Absence of the Pericardium
نویسندگان
چکیده
A healthy 19-year-old man was referred to our hospital due to an elongated left heart border on chest radiograph. Transthoracic echocardiography showed a posteriorly deviated left ventricular apex, increased right ventricular dimension, and hypokinesis of the interventricular septum. Pulsed Doppler echocardiogram revealed a triphasic mitral inflow pattern. Myocardial longitudinal strain rate imaging revealed that the early diastolic strain rate abruptly decreased to a negative value and then became positive at the left ventricular apex. In this case of an absent pericardium, the triphasic mitral inflow pattern might have been caused by an early diastolic shortening and subsequent elongation at the apex.

Triphasic mitral inflow velocity with mid-diastolic flow: the presence of mid-diastolic mitral annular velocity indicates advanced diastolic dysfunction.
Mitral inflow filling pattern usually consists of 2 forward flow velocities in sinus rhythm: early rapid filling (E) and late filling with atrial contraction (A). However, additional mid-diastolic flow velocity may be present resulting in triphasic mitral inflow filling pattern. When mitral inflow is triphasic, mitral annulus velocity recorded by tissue Doppler imaging (TDI) frequently demonstr...
متن کاملPacman Heart as a Congenital Cardiac Defect Associated with Flail Mitral Valve and a Partial form of Shone\'s Complex; A Case Report
Partial muscular inter-ventricular septal defect (VSD) or Pacman heart is a rare congenital or occasionally acquired anomaly. Concurrent Pacman heart and Shone's complex are extremely rare and have never been reported until now. We described a 37-year-old male patient with congenital Pacman heart, flail mitral valve (FMV), and a history of multiple congenital anomalies, including subvalvular ao...
متن کاملCONGENITAL PARTIAL PERICARDIAL DEFECT WITH HERNIATION OF THE LEFT ATRIAL APPENDAGE
Congenital defects of the pericardium are considered rare. Until 1979 , the reported cases were only about 200.1 Total absence of the left pericardium is the most common defect2 and less common is a partial defect of the left pericardium. Other types, i.e. isolated right-sided defects, total pericardial absence and diaphragmatic pericardial defects are very rare.3 Before the last decade, t...
متن کاملEchocardiography in Congenital and Acquired
O CONGENITAL ABSENCE of the pericardium is a well described but uncommon condition.'`9 In 1959, Ellis et al.2 noted that in the vast majority of cases partial or complete left-sided pericardial defects were present; right-sided or total pericardial absence is extremely rare. Although characteristic roentgenographic findings are usually present in congenital absence of the pericardium, clinicall...
متن کاملCongenital left ventricular inflow obstruction evaluated by two-dimensional echocardiography.
Several forms of congenital heart disease that cause left ventricular inflow obstruction have similar M-mode findings, and frequently the exact anatomic diagnosis cannot be made by M-mode echocardiography alone. We examined five children with various forms of left ventricular inflow obstruction using two-dimensional echocardiography. The diagnosis was confirmed by cardiac catheterization and su...
