An Unusual Cause of Hypoxia: Ventricular Septal Defect, Pulmonary Artery Atresia, and Major Aortopulmonary Collaterals Diagnosed in the Adult Cardiac Catheterization Lab.

ABSTRACT: The association of pulmonary atresia, ventricular septal defect (VSD) and major aortopulmonary collaterals (MAPCA) is an extreme form of tetralogy of Fallot (TOF). It carries a high mortality risk if not intervened on during infancy with only 20% of unoperated patients surviving into adulthood. We present the case of a 40-year-old man who presented for evaluation prior to retinal surgery and was found to have hypoxia and a loud murmur. Cardiac catheterization was performed in the general catheterization laboratory, demonstrating a membranous VSD, pulmonary atresia, and MAPCA. We highlight the challenges and limitations that an adult interventional cardiologist may have when encountering these patients.

Identification of Rare Copy Number Variants Associated With Pulmonary Atresia With Ventricular Septal Defect.

Project description:Copy number variants (CNVs) are major variations contributing to the gene heterogeneity of congenital heart diseases (CHD). pulmonary atresia with ventricular septal defect (PA-VSD) is a rare form of cyanotic CHD characterized by complex manifestations and the genetic determinants underlying PA-VSD are still largely unknown. We investigated rare CNVs in a recruited cohort of 100 unrelated patients with PA-VSD, PA-IVS, or TOF and a population-matched control cohort of 100 healthy children using whole-exome sequencing. Comparing rare CNVs in PA-VSD cases and that in PA-IVS or TOF positive controls, we observed twenty-two rare CNVs only in PA-VSD, five rare CNVs only in PA-VSD and TOF as well as thirteen rare CNVs only in PA-VSD and PA-IVS. Six of these CNVs were considered pathogenic or potentially pathogenic to PA-VSD: 16p11.2 del (PPP4C and TBX6), 5q35.3 del (FLT4), 5p13.1 del (RICTOR), 6p21.33 dup (TNXB), 7p15.2 del (HNRNPA2B1), and 19p13.3 dup (FGF22). The gene networks showed that four putative candidate genes for PA-VSD, PPP4C, FLT4, RICTOR, and FGF22 had strong interaction with well-known cardiac genes relevant to heart or blood vessel development. Meanwhile, the analysis of transcriptome array revealed that PPP4C and RICTOR were also significantly expressed in human embryonic heart. In conclusion, three rare novel CNVs were identified only in PA-VSD: 16p11.2 del (PPP4C), 5q35.3 del (FLT4) and 5p13.1 del (RICTOR), implicating novel candidate genes of interest for PA-VSD. Our study provided new insights into understanding for the pathogenesis of PA-VSD and helped elucidate critical genes for PA-VSD.

Unusual association of aortic valve stenosis with ventricular septal defect and pulmonary atresia: Differentiation from truncus arteriosus with truncal valve stenosis.

Project description:Stenosis of systemic semilunar valve in cyanotic congenital heart defects is rare. It can happen in truncus arteriosus with truncal valve stenosis and the very rare anomaly of tetralogy of fallot with aortic valve stenosis. Here we describe a neonate with pulmonary atresia, ventricular septal defect and associated aortic valve stenosis and discuss the points of differentiation from truncus arteriosus.

Current era outcomes of pulmonary atresia with ventricular septal defect: A single center cohort in Thailand.

Project description:Pulmonary atresia with ventricular septal defect (PA/VSD) is a complex cyanotic congenital heart disease with a wide-range of presentations and treatment strategies, depending on the source of pulmonary circulation, anatomy of pulmonary arteries (PAs), and major aortopulmonary collateral arteries (MAPCAs). Data about the outcomes in developing countries is scarce. We therefore conducted a retrospective study to assess survival rates and mortality risks of 90 children with PA/VSD at Siriraj Hospital, Thailand during 2005-2016. Patients with single ventricle were excluded. Survival and mortality risks were analyzed at the end of 2018. The median age of diagnosis was 0.5 (0-13.8) years. The patients' PAs were categorized into four groups: 1) PA/VSD with confluent PAs (n = 40), 2) PA/VSD with confluent PAs and MAPCAs (n = 21), 3) PA/VSD with non-confluent PAs and MAPCAs (n = 12), and 4) PA/VSD with small native PAs and MAPCAs (n = 17). Of the 88 patients who underwent operations, 32 patients had complete repair at 8.4 ± 4.6 years old. During the follow-up [median time of 5.7 years (7 days-13.6 years)], 17 patients (18.9%) died. The survival rates at 1, 5, and 10 years of age were 95%, 83.7%, and 79.6%, respectively. Significant mortality risks were the presence of associated anomalies and non-confluent PAs.

Ventricular Septal Defect from Takotsubo Syndrome.

Project description:Takotsubo Syndrome is a transient condition characterized by left ventricular systolic dysfunction with apical akinesis/dyskinesis and ballooning. Although the prognosis with medical management is excellent in most cases, rare cases of serious complications can occur. We present here a case of a 71-year-old woman presenting with acute decompensated heart failure with initial findings consistent with a myocardial infarction, who was found instead to have an acute ventricular septal defect as a complication of Takotsubo Syndrome.

Ventricular septal defect and bivalvular endocarditis.

Project description:A 63-year-old man presented with generalized fatigue, chills, malaise, dyspnea, intermittent fevers, and 50-pound weight loss of 4 months' duration. Blood cultures were positive for pan-sensitive Streptococcus anginosus. Transesophageal echocardiography showed an 11 mm × 3 mm mobile mass attached to the mitral valve, a 16 mm × 16 mm mobile mass attached to the pulmonary valve, and a small membranous ventricular septal defect. The patient received 12 weeks of intravenous (IV) antibiotics with eventual resolution of the masses. Multi-valve endocarditis involving both the left and right chambers is rarely reported without prior history of IV drug use or infective endocarditis. Our case emphasizes the importance of careful assessment for ventricular septal defects or extra-cardiac shunts in individuals who present with simultaneous right and left-sided endocarditis.

Stenting of modified Blalock-Taussig shunt in adult with palliated pulmonary atresia and ventricular septal defect: a case report.

Project description:BackgroundAdults with complex congenital heart disease palliated with systemic-to-pulmonary artery shunts have become rare and represent a particularly challenging patient group for the cardiologist. One of the complications and causes of severe clinical deterioration during long-term follow-up are progressive obstruction or total occlusion of the shunt. The risk for surgical intervention is frequently high and catheter intervention may be complicated by complex anatomy and shunt calcification.Case summaryWe report the case of a 47-year-old man with uncorrected (palliated) pulmonary atresia and ventricular septal defect who presented with progressive cyanosis (oxygen saturation 69%) and decreasing exercise capacity. Computed tomography revealed a totally occluded modified left Blalock-Taussig (BT) shunt and a severely stenosed central shunt (Waterston-Cooley) in a patient with confluent but hypoplastic pulmonary arteries and multiple major aortic pulmonary collaterals. Due to a high operative risk, an interventional, percutaneous approach was preferred to re-do surgery. From a radial access the calcified BT shunt could be crossed with a hydrophilic guidewire. Then, a rotational thrombectomy, balloon dilatation, and bare-metal stenting at the proximal and distal anastomoses were performed. Post-interventionally, peripheral oxygen saturation increased from 69% to 82%. Clopidogrel was administered for 1 month after bare-metal stenting. At 1-year follow-up, the BT shunt was still patent on echocardiography and exercise tolerance markedly improved.DiscussionThis case highlights the benefit of percutaneous rotational thrombectomy followed by stenting of chronically occluded systemic-to-pulmonary artery shunts for further palliation in adult patients with complex congenital heart disease not suitable for surgical repair.
