Restrictive Right Ventricular Physiology
نویسنده
چکیده
Methods A total of 43 consecutive patients (age 44 10 years) with moderate to severe PVS referred to Royal Brompton Hospital from 2002 to 2005 were retrospectively studied. Patient New York Heart Association (NYHA) functional class was recorded. The RV (lateral tricuspid annulus motion) long-axis movement was measured by M-mode and pulsed-wave (PW) tissue Doppler imaging (TDI). Restrictive RV physiology was assessed by PW Doppler echocardiography.

Restrictive right ventricular physiology after tetralogy of Fallot repair is associated with fibrosis of the right ventricular outflow tract visualized on cardiac magnetic resonance imaging.
AIMS To determine whether the restrictive physiology seen in Tetralogy of Fallot (TOF) patients can be explained by fibrosis of the right ventricular (RV) outflow tract. The aetiology for restrictive RV physiology after TOF repair is not known. METHODS AND RESULTS TOF patients (n = 31, 13 girls, 10.2 years ± 2.8) were included 9.2 ± 2.9 years after total correction and examined with cardiac m...
متن کاملDoes restrictive right ventricular physiology in the early postoperative period predict subsequent right ventricular restriction after repair of tetralogy of Fallot?
OBJECTIVE To assess the relation between immediate postoperative right ventricular (RV) diastolic physiology and subsequent diastolic function in patients after repair of tetralogy of Fallot. DESIGN Serial prospective echocardiographic study early after surgical repair of tetralogy of Fallot and at mid-term follow up. SETTING Tertiary referral centre. PATIENTS 34 patients who had repair o...
متن کاملRestrictive right ventricular performance assessed by cardiac magnetic resonance after balloon valvoplasty of severe pulmonary stenosis in adolescents
Background The fundamental abnormality of restrictive right ventricle (RV) physiology is reduced RV compliance as a result of chronic increase in pressure overload. In this study, we test the hypothesis that the persistence of Restrictive RV physiology after balloon pulmonary valvoplasty (BPV) is related to RV fibrosis assessed by Gadolinium-DTPA delayed-enhancement magnetic resonance imaging (...
متن کاملCardiorespiratory responses to negative pressure ventilation after tetralogy of fallot repair: a hemodynamic tool for patients with a low-output state.
OBJECTIVES We hypothesized that a period of cuirass negative pressure ventilation (NPV) would augment the cardiac output of patients in the early postoperative period after complete correction of tetralogy of Fallot (TOF). BACKGROUND Diastolic right ventricular dysfunction can lead to a low-output state in an important minority of patients after TOF repair. In these patients, the diastolic pu...
متن کاملRight ventricular diastolic dysfunction in the postoperative period of tetralogy of Fallot.
OBJECTIVE To assess right ventricular diastolic function in the intermediate postoperative period of repair of tetralogy of Fallot. METHODS We carried out a case-control study with 60 patients divided into 2 groups as follows: 1) group I - 30 patients who had undergone repair of tetralogy of Fallot and 2) group II - 30 healthy children. The 2 groups were paired for age, sex, and body surface....
متن کاملAcute right ventricular restrictive physiology after repair of tetralogy of Fallot: association with myocardial injury and oxidative stress.
BACKGROUND Acute right ventricular (RV) restrictive physiology after tetralogy of Fallot repair results in low cardiac output and a prolonged stay in the intensive care unit (ICU). However, its mechanism remains uncertain. METHODS AND RESULTS In the first 24 hours after tetralogy of Fallot repair (n=11 patients), serial prospective measurements were performed of cardiac troponin T, indexes of...
