چکیده
background total correction of tetralogy of fallot (tof) anomaly in early childhood has been practiced in many centers with good results, but in some of patients after few years sever pulmonary valve insufficiency occurred. materials and methods at a cross- sectional study from january 2015 to january 2016, 10 patients who had history of primary repair of tof with free pulmonary insufficiency (pi) that underwent of pulmonary valve replacement (pvr) with bioprosthetic valves were evaluated. results themean age of patients was 6.5 + 0.753 years old (ranged 8-12 years old) and male to female ratio was 6/4. the mean of intensive care unit (icu) stay and hospital stay was 4.5+ 0.712 days (ranged 3-8) and 11.5+ 0.357 days (ranged 9- 16). mean of cardiopulmonary bypass time and operation time was 45 + 0.684 min (ranged 32-60) and 83 + 0.317 min (ranged 65-112). in this study we did not find any mortality and ventricular arrhythmia and heart block. there was only one case (10%) with superficial wound infection that was controlled. at 6 months follow up, all of patients were alive, but echocardiography sign of right ventricular (rv) failure was present in 2 patients (20%) recently. conclusion although for pulmonary insufficiency after primary tof repair there is controversial in studies, but we had good results of pvr with bioprosthesis in tof patients.

متن کاملPulmonary valve replacement after correction of Tetralogy of Fallot
BACKGROUND Correction of tetralogy of Fallot often leads to pulmonary regurgitation, sometimes warranting pulmonary valve replacement, for which indications and timing to achieve optimal results are not yet clear. This retrospective study describes follow-up and reinterventions in our tetralogy of Fallot population. METHODS Review of all consecutive patients operated on for tetralogy of Fallo...

OBJECTIVES Pulmonary valve replacement (PVR) is performed to reduce right ventricular (RV) volume overload, resulting in improved ventricular function and clinical status. Significant pulmonary regurgitation (PR) after tetralogy of Fallot (TOF) repair could result in RV dysfunction, exercise intolerance, arrhythmia and sudden death. The present study was conducted to investigate the mid-term cl...

A 32-year-old woman with a history of tetralogy of Fallot (TOF) was referred for cardiac evaluation. She was diagnosed with TOF as an infant and at 8 months of age underwent complete repair, including ven-tricular septal defect closure, resection of right ventricular (RV) outflow tract (RVOT) muscle bundles, and pulmonary valvotomy. She was evaluated by a cardiologist at 17 years of age and was...

BACKGROUND Chronic pulmonary regurgitation after repair of tetralogy of Fallot (TOF) may lead to right ventricular dilatation, which may be accompanied by ventricular tachycardia and sudden death. We aimed to examine the effects of pulmonary valve replacement (PVR) on (1) certain electrocardiographic markers predictive of monomorphic ventricular arrhythmia and sudden death and (2) sustained atr...
