Simplified percutaneous closure of patent foramen ovale and atrial septal defect with use of plain fluoroscopy: Single operator experience in 110 consecutive patients.

ABSTRACT: OBJECTIVE:Percutaneous closure of patent foramen ovale (PFO) and atrial septal defect (ASD) is routinely performed under general anesthesia or deep sedation and use of transesophageal (TEE) or intracardiac echocardiography, incurring longer duration and higher cost. We have used a simplified, economical, fluoroscopy-only guided approach with local anesthesia, and herein report our data. METHODS:The study includes 112 procedures in 110 patients with PFO (n=75) or ASD (n=35), with use of an Amplatzer occluder, heparin and prophylactic antibiotics. Balloon sizing guided ASD-device selection. All patients received aspirin and clopidogrel for 6 months, when they all underwent TEE. RESULTS:All PFOs but one (98.7%) and all (100%) ASDs were successfully closed with only one complication (local pseudoaneurysm). At the 6-month TEE, there was no residual shunt in PFO patients, but 2 ASD patients had residual shunts. During long-term (4.3-year) follow-up, no stroke recurrence in PFO patients, and no other problems were encountered. Among 54 patients suffering from migraine, symptom relief or resolution was reported by 45 (83.3%) patients. CONCLUSION:Percutaneous placement of an Amplatzer occluder was safe and effective with use of local anesthesia and fluoroscopy alone. There were no recurrent strokes over >4 years. Migraine relief was reported by >80% of patients.

Project description:Patent foramen ovale (PFO)-related stroke is increasingly recognized as an important etiology of ischemic embolic stroke-accounting for up to 50% of strokes previously considered 'cryptogenic' or with an unknown mechanism. As a 'back door to the brain,' PFO can allow venous clots to enter arterial circulation via interatrial right-to-left shunting, potentially resulting in ischemic stroke. We observe that clinically, PFO-related stroke affects women of childbearing age, and that pregnancy-owing to major changes in hemocoagulative, hormonal, and cardiovascular parameters-can enhance stroke risks. However, no systematic study has been performed and little is known regarding complications, pregnancy outcomes and treatment for PFO-related stroke during pregnancy. To identify and characterize the complications and clinical outcomes related to PFOs during pregnancy, we performed a literature review and analysis from all reported cases of pregnancy with PFO-related complications in the medical literature from 1970 to 2015. We find that during pregnancy and post-partum, PFO is associated with complications affecting multiple organs, including the brain, heart and lung. The three principal complications reported are stroke, pulmonary emboli and myocardial infarction. In contrast to other pregnancy-related stroke etiologies, which peak during later pregnancy and postpartum, PFO-related stroke peaks during early pregnancy (first and second trimester-60%), and most patients had good neurological outcome (77%). In patients with PFO with recurrent stroke during pregnancy, additional key factors include high-risk PFO morphology (atrial septal aneurysm), larger right-to-left shunt, multiple gestation and concurrent hypercoagulability. Compared to strokes of other etiologies during pregnancy, most PFO stroke patients experienced uneventful delivery (93%) of healthy babies with a good clinical outcome. We conclude with recommended clinical treatment strategies for pregnant patients with PFO suggested by the data from these cases, and the clinical experience of our Cardio-Neurology Clinic.

Project description:BackgroundTranscatheter atrial septal defect (ASD) and patent foramen ovale (PFO) closure might have opposite short- and long-term haemodynamic consequences compared with restricted interatrial shunt creation, which recently emerged as a potential treatment modality for patients with heart failure with preserved ejection fraction (HFpEF). Given the opposing approaches of ASD and PFO closure versus shunt creation, we investigated the early and sustained cardiac structural and functional changes following transcatheter ASD or PFO closure.MethodsIn this retrospective study, adult secundum-type ASD and PFO patients with complete echocardiography examinations at baseline and at 1‑day and 1‑year follow-up who also underwent transcatheter closure between 2013 and 2017 at the University Medical Centre Groningen, the Netherlands were included.ResultsThirty-nine patients (mean age 48 ± standard deviation 16 years, 61.5% women) were included. Transcatheter ASD/PFO closure resulted in an early and persistent decrease in right ventricular systolic and diastolic function. Additionally, transcatheter ASD/PFO closure resulted in an early and sustained favourable response of left ventricular (LV) systolic function, but also in deterioration of LV diastolic function with an increase in LV filling pressure (LVFP), as assessed by echocardiography. Age (β = 0.31, p = 0.009) and atrial fibrillation (AF; β = 0.24, p = 0.03) were associated with a sustained increase in LVFP after transcatheter ASD/PFO closure estimated by mean E/e' ratio (i.e. ratio of mitral peak velocity of early filling to diastolic mitral annular velocity). In subgroup analysis, this was similar for ASD and PFO closure.ConclusionOlder patients and patients with AF were predisposed to sustained increases in left-sided filling pressures resembling HFpEF following ASD or PFO closure. Consequently, these findings support the current concept that creating a restricted interatrial shunt might be beneficial, particularly in elderly HFpEF patients with AF.
