William Harvey was the first scientist to describe the heart as consisting of separate right- and left-sided circulations. Our understanding of the heart’s anatomy and physiology has grown significantly since this landmark discovery in 1628. Today, we recognise not only the importance of these separate systems, but also the specific tissue that divides them. Our growing understanding of the inter-atrial septum has allowed us to identify defects within this structure and develop effective percutaneous devices for closure of these defects in the adult patient. This article discusses the formation of a patent foramen ovale (PFO) and atrial septal defect (ASD). In addition, we describe the medical illnesses caused by these defects and summarise the indications and risks related to percutaneous closure of these defects. We also report the most up-to-date transcatheter therapeutic options for closure of these common congenital defects in the adult patient.

Abstract It is not uncommon to have prolapse of the atrial septal occluder device despite accurate measurement of atrial septal defect and an appropriately chosen device. This is particularly a problem in cases with large atrial septal defect with absent aortic rim. Various techniques have been described for successful implantation of atrial septal occluder in such a scenario. The essence of all these techniques is to prevent prolapse of the left atrial disc through the defect while the right atrial disc is being deployed. In this brief report, we illustrate the use of cobra head deformity of the device to successfully deploy the device across the atrial septum.

Abstract Background Carcinoid heart disease is present in approximately 20% of the patients with carcinoid syndrome and is associated with poor prognosis. It usually manifests with right-sided valvular involvement including tricuspid insufficiency and pulmonary stenosis. Patent foramen ovale (PFO) is present in approximately 50% of the patients with carcinoid heart disease which is twice higher than the general population. Right-to-left shunting through a PFO can occur either due to higher right atrial pressure than left (pressure-driven) or when the venous flow is directed towards the PFO (flow-driven) in the setting of normal intracardiac pressures. We report a rare case of flow-driven right-to-left atrial shunting via PFO in a patient with carcinoid heart disease. Case summary A 54-year-old male with a metastatic neuroendocrine tumour to liver presented with progressive shortness of breath for 5 months. Patient was found to be hypoxic with oxygen saturation of 78% and examination revealed a holosystolic murmur. Arterial blood gas showed oxygen tension of 43 mmHg. A transthoracic and transoesophageal echocardiogram showed aneurysmal inter-atrial septum with a PFO, severe tricuspid regurgitation directed anteriorly towards the inter-atrial septum leading to a marked right-to-left shunt. Right heart catheterization showed right atrial pressure of 8 mmHg, mean pulmonary artery pressure of 12 mmHg, and normal oxygen saturations in the right atrium, right ventricle, and pulmonary arteries. The patient then underwent closure of the PFO along with tricuspid valve and pulmonary valve replacement at an experienced cardiovascular surgical centre and has been asymptomatic since. Conclusion Right-to-left shunting through a PFO in patients with normal right atrial pressure can be successfully treated with closure of the PFO. Thus, understanding the mechanism of intracardiac shunts is important to accurately diagnose and treat this rare and fatal condition.
