ABSTRACT
BACKGROUND: Congenital heart disease is an abnormality of anatomical structure of the heart that is of paramount importance. The incidence is approximately 8 per 1000 live births. CHD not only contributes to signi?cant mortality and morbidity but also causes tremendous psychological stress and economical burden to whole family. OBJECTIVE: To study the pattern and clinical pro?le of congenital heart diseases in a tertiary care hospital and to aid for early stdetection and quick referral of children with congenital heart disease In this study, done between January 1 2020 to RESULTS: june 31st 2021, 54 children with con?rmed congenital heart disease were observed. ACHD was the most common type of CHD and of them, VSD was the most common type, followed by ASD. Based on sex distribution, 31 were male (55.5%) and 23 were female (44.5%), with a male: female ratio of 1.25:1. Most children belonged in the age group 6m – 1year (46.2%) followed by (42.5%) in 30days – 6months age. The common clinical presentation observed in this study was breathlessness. The common complication observed in the current study was heart failure followed by malnourishment and recurrent LRTI.
ABSTRACT
Pregnant patients with uncorrected Double Outlet Right Ventricle (DORV) undergoing cesarean section are challenging for anesthesiologists. We present a case of a 24?year?old woman with a gestational age of 30–32 weeks with DORV, ventricular septal defect, pulmonary hypertension, and stage C functional class III heart failure who was successfully managed using a combination of low?dose spinal anesthesia bupivacaine 0.5% 7.5 mg with adjuvant fentanyl 50 mcg and epidural ropivacaine 0.2%, and fentanyl 50 mcg TV 10 cc given 30 minutes after the birth of her baby. Hemodynamics was stable after low?dose spinal anesthesia and until the end of the operation.
ABSTRACT
ObjectiveT o explore the influence of patch shape for intraventricular tunnel (IVT) construction on biomechanical performance of the double outlet right ventricle after correction. Methods Based on the idealized IVT model, a two-dimensional IVT patch was designed. Six groups of patch models with the rhombic long-to-short axis ratio of 1∶0.625, 1∶0.3, 1∶0.2, 1∶0.15, 1∶0.125, 1∶0.1 were established according to the difference between the long and short axis of the rhombus patch in the turning part, and finite element analysis method was used to numerically simulate the process of stitching, holding and propping up the patch into a three-dimensional (3D) IVT model. Results The maximum stresses on suture line of 6 patch models were mainly concentrated at acute-angle corners of the rhombus. As rhombic long-to-short axis ratio of the patch increased, the maximum stress of the IVT suture line first decreased and then increased, and the volume showed an increasing trend. The pressure difference between two ends of the tunnel first decreased and then increased. The patch with the long-to-short axis ratio of 1∶0.15 had a uniform surface stress distribution, and the maximum stress on the suture line was the smallest. Meanwhile the right ventricular volume was less encroached on, and the pressure difference at both ends of the tunnel was small. Conclusions The IVT shape can influence stresses of suture line, the right ventricle volume and the pressure difference of IVT with non-monotonic variations. The suture effect of the patch with the long-to-short axis ratio of 1∶0.15 is relatively better among the constructed models.
ABSTRACT
Congenital Heart Diseases (CHD) lead to various changes in the normal mechanisms of hemodynamics. Pregnancy in women with CHDs is rare. Double Outlet Right Ventricle (DORV) is a rare disorder, in which both the aorta and the pulmonary artery arise from the right ventricle. We present a case of a thirty-year-old pregnant woman who presented to us with 22 weeks of amenorrhea. She had DORV with VSD, which was undiagnosed till she came to our hospital. Double Outlet Right Ventricle (DORV) is a rare congenital heart disease. Pregnancy in a patient with DORV needs early diagnosis and a stepwise multidisciplinary approach for successful outcomes.
ABSTRACT
We report a case of DORV in an 18-year-old female patient presented to NIMS Medical College and Hospital with unrelated symptoms of urinary tract infection. Diagnosis of this case is made by 2D-echocardiography with cardiologist consultation.
ABSTRACT
Regardless of the preoperative morphology and the type of operation, left ventricular outflow tract obstruction (LVOTO) after biventricular repair of double outlet right ventricle (DORV) may develop. This report presents our 10-yr experience with surgical management of LVOTO after biventricular repair of DORV. Between 1996 and 2006, 15 patients underwent reoperation for subaortic stenosis after biventricular repair of DORV. The mean age at biventricular repair was 23.3+/-18.3 months (1.1-64.2). Biventricular repairs included tunnel constructions from the left ventricle to the aorta in 14 cases and an arterial switch operation in one. The mean left ventricle-to-aorta peak pressure gradient was 54.0+/-37.7 mmHg (15-140) after a mean follow-up of 9.5+/-6.3 yr. We performed extended septoplasty in nine patients and fibromuscular resection in six. There were no early or late mortality. There was one heart block and one aortic valve injury after an extended septoplasty, and two and one after a fibromuscular resection. No patient required reoperation for recurrent subaortic stenosis. The mean pressure gradient was 11.2+/-11.4 mmHg (0-34) after a mean follow-up of 5.6+/-2.7 yr. Extended septoplasty is a safe and effective method for the treatment of subaortic stenosis, especially in cases with a long-tunnel shaped LVOTO.

Intracardiac repair for cardiac anomalies associated with a transposed aorta from the right ventricle is a technically demanding operation. We present two cases of left ventricular outflow tract (LVOT) obstruction after the use of an ePTFE flat patch to reconstruct the LVOT. Case 1 : A 10-year-old boy had undergone the Rastelli operation, VSD enlargement, and intraventricular re-routing using an ePTFE flat patch for repair of the DORV with noncommitted VSD and pulmonary stenosis at the age of 5. Five years later, catheter examination revealed severe LVOT obstruction. Intraventricular re-routing using a part of the ePTFE graft concomitant with re-replacement of an extracardiac conduit was successfully performed. Case 2 : A 13-year-old girl had undergone a double-switch operation (Senning operation, the Rastelli operation, and intraventricular re-routing by the use of an ePTFE flat patch) for the repair of corrected TGA, PA and VSD at the age of 7. Six years later, catheter examination revealed severe LVOT obstruction. Intraventricular re-routing using part of the ePTFE graft concomitant with re-replacement of an extracardiac conduit was successfully performed. We consider that the use of a flat patch for reconstruction of a left ventricular out flow tract in cases with transposition of the aorta from the right ventricle involves a risk of future development of LVOT obstruction.
