REVIEW ARTICLE
Surgery for transposition of great arteries: A historical perspective
Supreet P Marathe, Sachin Talwar
May-August 2015, 8(2):122-128
DOI:10.4103/0974-2069.157025  PMID:26085763
The history of surgery for transposition of great arteries (TGA) has paralleled the history of cardiac surgery. In fact, it began before the birth of open heart surgery when the palliative Blalock-Hanlon septectomy was first performed in 1948. The atrial switch, which was an attempt to correct the physiology of transposition, had significant shortcomings. The arterial switch sought to address them. This has emerged as an anatomically as well as physiologically appropriate solution. Today we continue to pursue technical refinements as well as try to expand the indications of the arterial switch. This review traces the various milestones in this perpetual journey.

Diagnosis and management of aorto-left ventricular tunnel
Pallavi Kathare, Rama G Subramanyam, Tapan Kumar Dash, Kalyana Sundaram Muthuswamy, K Raghu, Nageswara Rao Koneti
May-August 2015, 8(2):103-107
DOI:10.4103/0974-2069.157021  PMID:26085759
Background: Aorto-left ventricular tunnel (ALVT) is a rare congenital extracardiac channel with progressive left ventricular dilatation needs early correction. Materials and Methods: This is a report of diagnosis and management of aorto-left ventricular tunnel (ALVT) over a period of 11 years from a single institution. Seven patients (age range: 7 days-45 years) presented with heart failure. The diagnosis of ALVT was made by transthoracic echocardiogram in all cases. Results: Treatment was refused by two patients who died during follow-up. Surgical closure of the tunnel was done in four cases, of which one needed Bentall procedure. Two patients had residual leak after the surgery. Transcatheter closure using Amplatzer muscular device was performed in two cases (for postoperative residual leak in one and primary procedure in the other). Significant hemolysis developed in one of them, necessitating the removal of the device and closed surgically. This child underwent aortic valve replacement two years later. All the remaining patients were doing well during the median follow-up of 30 months (range: 1.5-9 years). Conclusion: ALVT is a rare and potentially fatal anomaly that is ideally managed surgically. Catheter closure has a limited role.

PRKAG2 mutation: An easily missed cardiac specific non-lysosomal glycogenosis
Varun Aggarwal, Nancy Dobrolet, Steven Fishberger, Jenny Zablah, Parul Jayakar, Zineb Ammous
May-August 2015, 8(2):153-156
DOI:10.4103/0974-2069.154149  PMID:26085771
Mutations in PRKAG2 gene that regulates the γ2 subunit of the adenosine monophosphate (AMP) dependent protein kinase have been associated with the development of atrioventricular (AV) accessory pathways, cardiac hypertrophy, and conduction system abnormalities. These patients can potentially be misdiagnosed as hypertrophic cardiomyopathy (HOCM) and/or Wolf-Parkinson White (WPW) syndrome due to similar clinical phenotype. Early recognition of this disease entity is very important as ablation of suspected accessory pathways is not effective and the natural history of the disease is very different from HOCM and WPW syndrome.

Improved quality of life after treatment of prolonged asystole during breath holding spells with a cardiac pacemaker
Bruno Kolterer, Roman Antonin Gebauer, Jan Janousek, Ingo Dähnert, Frank Thomas Riede, Christian Paech
May-August 2015, 8(2):113-117
DOI:10.4103/0974-2069.154142  PMID:26085761
Objectives: To validate the physical and psychological effectiveness of cardiac pacing in pediatric patients with breath-holding spells (BHS) and prolonged asystole. Materials and Methods: The records and clinical data of all the patients with BHS who presented to our center in the period of 2001-2013 were reviewed. All patients who received cardiac pacemaker implantation for prolonged asystole during BHS were included. In addition, the parents were asked to fill out a standardized quality of life (QOL) questionnaire. Results: Seven patients were identified. The mean onset of symptoms was 7 month (1-12 months) of age, documented asystole was 12-21 seconds, and a permanent cardiac pacemaker device was implanted at a mean age of 23 months (8 months-3.9 years). No pacemaker related adverse events were recorded. Follow up showed immediate resolution from spells in four cases (4/7). Two patients (2/7) showed significant reduction of frequency and severity of spells, with complete elimination of loss of consciousness (LOC). One patient (1/7) with an additional neurologic disorder continued to have minor pallid BHS and eventually switched from pallid to cyanotic spells without further detection of bradycardia or asystole in holter examination. QOL questionnaire revealed significant reduction in subjective stress levels of patients (P = 0.012) and parents (P = 0.007) after pacemaker implantation. Conclusion: Cardiac pacing using appropriate pacemaker settings seems effective in the prevention of LOC and reduction of the frequency of BHS. Our results imply a reduction of subjective stress levels of patients and parents as well as an increased quality of everyday life. After all, randomized controlled trials of the influence of cardiac pacemaker implantation on subjective stress levels in patients with BHS are needed.

Daniel Engelman, Joseph H Kado, Bo Reményi, Samantha M Colquhoun, Caroline Watson, Sera C Rayasidamu, Andrew C Steer
May-August 2015, 8(2):118-121
DOI:10.4103/0974-2069.157024  PMID:26085762
Screening for rheumatic heart disease (RHD) requires workers skilled in echocardiography, which typically involves prolonged, specialized training. Task shifting echocardiographic screening to nonexpert health workers may be a solution in settings with limited human resources. An 8-week training program was designed to train health workers without any prior experience in focused echocardiography for RHD screening. Seven health workers participated. At the completion of training, the health workers performed unsupervised echocardiography on 16 volunteer children with known RHD status. A pediatric cardiologist assessed image quality. Participants provided qualitative feedback. The quality of echocardiograms were high at completion of training (55 of 56 were adequate for diagnosis) and all cases of RHD were identified. Feedback was strongly positive. Training health workers to perform focused echocardiography for RHD screening is feasible. After systematic testing for accuracy, this training program could be adapted in other settings seeking to expand echocardiographic capabilities.

Pulmonary function testing in infants with tetralogy of Fallot and absent pulmonary valve syndrome
Adler M Salazar, Christopher CJL Newth, Robinder G Khemani, Hammer Jürg, Patrick A Ross
May-August 2015, 8(2):108-112
DOI:10.4103/0974-2069.154152  PMID:26085760
Aim: Absent pulmonary valve syndrome (APVS) is found in 3-6% of patients with Tetralogy of Fallot (TOF). Along with findings of TOF, absence of pulmonary valve tissue results in aneurysmal dilatation of the main and branch pulmonary arteries compressing the trachea, main-stem, and intrapulmonary bronchi leading to obstructive airways disease. Our objective was to review pulmonary function tests (PFT) in TOF-APVS patients. Materials and Methods: Eight PFT were performed on five mechanically ventilated TOF-APVS patients in the intensive care unit. Tidal volume, forced vital capacity (FVC), maximal expiratory flow 25%, resistance and compliance of the respiratory system were measured. Results: Pre-operative PFTs showed markedly elevated airways resistance (R RS ) (median 0.45 cmH 2 O/mL/sec, range 0.17-0.66) and marked variability of the static compliance of the respiratory system (C RS ) (median 0.6 mL/cmH 2 O/kg, range 0.25-2.6). Flow-volume loops measured by forced deflation showed flow limitation within the medium to small airways. Post-operative FVC was reduced in four of the five patients (median 46 mL/kg, IQR 42.9 - 48.8 mL/kg). Patients studied with various levels of positive end expiratory pressure (PEEP) showed improvement in tidal volume and reduced obstruction with PEEP greater than 10 cmH 2 O. For three patients with pre-operative data available, surgical correction resulted in near-normal post-operative C RS and improved, but still elevated R RS (median 0.14 cmH 2 O/mL/sec, interquartile range [IQR] 0.11-0.31). Conclusion: For our patients with TOF-APVS, airway resistance was elevated. Flow limitation was seen in the medium to small airways with a mild reduction of FVC. PFTs may help guide management of mechanical ventilation for TOF-APVS patients.

Alisa Arunamata, Stanton B Perry, Alaina K Kipps, Shreyas S Vasanawala, David M Axelrod
May-August 2015, 8(2):161-163
DOI:10.4103/0974-2069.154154  PMID:26085773
Isolation of the right subclavian artery (RSCA) is rare, and this finding in association with d-transposition of the great arteries (d-TGA) is extremely unusual. We present a case of an isolated RSCA in a newborn with d-TGA in whom the clinical presentation was diagnostic. We discuss the imaging modalities used to confirm the diagnosis, the embryological basis of the finding, and the surgical repair.

Tricuspid atresia and pulmonary atresia in a child with Rubinstein-Taybi syndrome
Rohit S Loomba, Gabrielle Geddes
May-August 2015, 8(2):157-160
DOI:10.4103/0974-2069.154151  PMID:26085772
Rubinstein-Taybi syndrome is a well-characterized condition causing distinctive physical characteristics, intellectual disability, and multiple congenital malformations. Cardiac abnormalities are found in a third of individuals with this condition and usually consist of isolated septal defects or patent ductus arteriosus, although more complex congenital lesions have been described. We present the first reported case of tricuspid atresia and pulmonary atresia with hypoplasia of the right ventricle in the setting of Rubenstein-Taybi syndrome.

Stent implantation of left main coronary artery stenosis in an infant: Effective long-term treatment?
Christian Paech, Ingo Dahnert, Frank Thomas Riede
May-August 2015, 8(2):147-149
DOI:10.4103/0974-2069.157035  PMID:26085769
Coronary artery stenosis is a rare phenomenon in children. Coronary stent implantation is generally not considered a standard treatment option due to technical difficulties and potential complications in this group of patients. Nevertheless, several pediatric cases reporting successful implantation with acceptable short-term experiences have been described. The following case presents a successful stent implantation for left main coronary artery (LMCA) stenosis early after surgery for anomalous left coronary artery from pulmonary artery (ALCAPA) at the age of 6 months. The excellent mid-term results and notably the procedure's potential as a long-term treatment in small children are highlighted. A 6-month-old infant underwent surgery for ALCAPA. Due to sudden postoperative deterioration, cardiac catheterization was performed. Coronary angiography revealed severe (90%) ostial LMCA stenosis. A PROMUS drug-eluting stent (Promus Element AL3.0 Χ 8 mm, Boston Scientific, Natick, Massachusetts, USA) was implanted. The procedure was performed without complications. Antiplatelet therapy with acetylsalicylic acid and clopidogrel was initiated. Subsequently, cardiac function improved slowly. Cardiac catheterization 3 years 8 months after stent implantation showed no restenosis with a proximal LMCA diameter still at the 50 th percentile for age. Neither were signs of heart failure reported at the last follow-up at 7 years of age. Presupposing normal growth, the implanted stent would thus provide sufficient myocardial perfusion with a LMCA lumen at the 40 th percentile at the age of 16 years. In selected cases, coronary stent implantation may be an effective mid- to long-term treatment of coronary artery stenosis even in very young children.

Surgicel® is bioabsorbable hemostatic mesh, frequently packed around oozing surgical bed. We report two morbidities due to it. Following transannular patch repair for Fallot's tetralogy, Surgicel® was packed around distal main pulmonary artery. Echocardiography in the intensive care unit (ICU) showed right ventricular dysfunction due to extrinsic obstruction and complete occlusion of left pulmonary artery (LPA) flows. Another patient with arterial switch operation had postoperative fibrillatory cardiac arrest, needing resuscitation with internal cardiac massage. The arrest was triggered by coronary ischemia due to periaortic compression. Both instances were caused by hygroscopic nature of Surgicel®, which absorbed blood, swelled, and compressed the luminal tissues.

Sudden cardiac death (SCD) most commonly results from previously undiagnosed congenital, acquired, or hereditary cardiac diseases. Congenital aortic valvular, subvalvular, and supravalvular disease with left ventricular outflow tract obstruction is an important preventable cause of sudden death. This report documents sudden death presumably due to acute myocardial ischemia in a young male with an undiagnosed supravalvular aortic stenosis (SVAS) due to a rare association of isolation of coronary sinuses of Valsalva. Congenital supravalvular pulmonary stenosis and mitral valvular dysplasia were also present.

Sri Lanka is an island nation in Indian Ocean that provides free healthcare to all citizens through government healthcare system. It has commendable health indices in the region. Pediatric cardiac services have rapidly progressed over past few years helping to further bring down infant and under-five mortality rates. Lady Ridgeway Hospital for Children (LRH) is the only tertiary care referral center for children with heart disease in the country. Currently it performs approximately 1,000 cardiac catheterizations and 1,000 cardiac surgeries every year. Target is to double the surgical output to treat all children with heart diseases in a timely and appropriate manner. Being a middle-income country, this is not an easy task. Technology used in diagnosis and treatment of congenital heart diseases is rapidly advancing with its price tag. In such a setting, it is challenging to proceed to achieve this target in a resource-limited environment.

Pseudoaneurysms of the ventricle are an uncommon occurrence in children. They may be secondary to previous cardiac surgery or infection of the pericardial space. Infective pseudoaneurysms require urgent surgery because rupture of the pseudoaneurysm may have catastrophic consequences. The outcome with surgery is excellent. We report a toddler with ruptured pseudoaneurysm secondary to purulent pericarditis who recovered with an emergency surgical closure of the opening of the pseudo-aneurysm.
