TL;DR: Tetralogy of Fallot is very rarely associated with persistent left superior vena cava which drains into left atrium, and four such cases who underwent surgical correction successfully are reported.
Abstract: Persistent left superior vena cava is a common congenital anomaly of the thoracic venous system. Left superior vena cava draining into left atrium is a malformation of sinus venosus and caval system. The anomaly may be a cause of unexplained hypoxia even in adults. It may give rise to various diagnostic and technical challenges during cardiac catheterization and open-heart surgery. It is often detected serendipitously during diagnostic workup. Isolated left superior vena cava opening into left atrium is very commonly associated with other congenital heart defects. But tetralogy of Fallot is very rarely associated with persistent left superior vena cava which drains into left atrium. We report four such cases who underwent surgical correction successfully.

TL;DR: Repairs of chordal rupture of the tricuspid valve in neonates using ePTFE neo-chordae can provide acute salvage and gratifying midterm results in the management of this potentially fatal condition.
Abstract: Background:Papillary muscle rupture in the perinatal period is a rare event that leads to severe mitral or tricuspid insufficiency due to a flail leaflet. Neonatal tricuspid chordal reconstruction ...

TL;DR: This work describes a patient with d-TGA, VSD, and LVOTO who presented to us at 13 years of age and underwent an arterial switch operation along with neoaortic valve replacement with a mechanical prosthesis and presents the pros and cons of this hitherto undescribed treatment option.
Abstract: The surgical management of d-transposition of great arteries (d-TGAs) with ventricular septal defect (VSD) and left ventricular outflow tract obstruction (LVOTO) is ever evolving and still remains a challenge because of wide anatomic variability, age of presentation, surgical options available, and their variable long-term results in different series. We describe a patient with d-TGA, VSD, and LVOTO who presented to us at 13 years of age and underwent an arterial switch operation along with neoaortic valve replacement with a mechanical prosthesis. The postoperative course was uneventful, and at hospital discharge, the echocardiogram was satisfactory. We present the pros and cons of this hitherto undescribed treatment option.

TL;DR: This review analyzes the history, physiology, techniques, as well as other alternative strategies like selective cerebral perfusion and presents the current available evidence to support the best way to protect the brain during congenital heart surgery.
Abstract: The use of total circulatory arrest (TCA)/deep hypothermic circulatory arrest (DHCA) as a support modality in congenital heart surgery is a time-tested strategy. However, with technological advances, the widespread use of this technique has decreased. Adjunctive cerebral perfusion with continuous cardiopulmonary bypass (CPB) gradually has become more popular with a view to reduce the complications related to DHCA. In addition, better neuromonitoring and neuroprotective strategies have made DHCA much safer. However, the level of evidence to support the best way to protect the brain during congenital heart surgery is insufficient. This review analyzes the history, physiology, techniques of DHCA, as well as other alternative strategies like selective cerebral perfusion and presents the current available evidence.

TL;DR: A case of left ventricular myxoma with very atypical cystic appearance raising an initial suspicion of a hydatid cyst was reported in this paper, where complete surgical excision was done through transaortic and transmitral route.
Abstract: Cardiac myxomas are the most common primary cardiac tumors and are typically attached to the interatrial septum. Left ventricular myxomas are exceedingly rare and presentation in children is all the more uncommon. We report a case of left ventricular myxoma with very atypical cystic appearance raising an initial suspicion of a hydatid cyst. Subsequently, cardiac magnetic resonance imaging was done, which ruled out the diagnosis of hydatid cyst. Complete surgical excision was done through transaortic and transmitral route. Histopathological examination revealed it to be a cardiac myxoma with vascular proliferation, which on echocardiography had appeared as a polycystic lesion. This is a very unusual histopathological presentation of cardiac myxoma.

TL;DR: In this paper, the authors report the follow-up from fetal life to the time of postnatal surgery of a patient with severe tricuspid regurgitation due to a flail of the anterior tricusid valve leaflet who was born to an anti-Ro/SSA antibodies positive mother.
Abstract: Valve dysfunction is not widely recognized as a feature in newborns born to mothers with positive anti-Ro/SSA antibodies, and only scarce reports have suggested an association between rupture of the atrioventricular valve tensor apparatus and these maternal antibodies. We report the follow-up from fetal life to the time of postnatal surgery of a patient with severe tricuspid regurgitation due to a flail of the anterior tricuspid valve leaflet who was born to an anti-Ro/SSA antibodies positive mother.

TL;DR: In this article , the authors present their experience of two cases, both of whom underwent a single-stage arterial switch operation and an aortic valve replacement for this defect.
Abstract: The surgical treatment of transposition of the great arteries, ventricular septal defect, and significant left ventricular outflow tract obstruction continues to evolve. The survival of an unrepaired transposition of the great arteries into late adulthood is a rarity. Even when large intracardiac shunts are present, it remains a lethal cyanotic CHD if it is not surgically corrected soon after birth. We present our experience of two cases, both of whom underwent a single-stage arterial switch operation and an aortic valve replacement for this defect.
TL;DR: In this article , a newborn presenting severe cyanosis after delivery was diagnosed with severe tricuspid regurgitation secondary to rupture of chordae tendineae by echocardiography (Echo).
Abstract: Unguarded severe tricuspid regurgitation caused by rupture of papillary muscle or chordae tendineae is rare but fatal in neonates. The experience in the management of these patients is still limited. A newborn presenting severe cyanosis after delivery was diagnosed with severe tricuspid regurgitation secondary to rupture of chordae tendineae by echocardiography (Echo), then treated by surgical reconstruction of chordae/papillary muscle connection without artificial materials. A takeaway lesson from this case is that Echo is an important method to diagnose a rupture of chordae tendineae or papillary muscle and that prompt diagnosis and timely surgery can be life-saving.
