The unnatural history of an atrial septal defect: Longitudinal 35 year follow up after surgical closure at young age
Conclusions
Very long-term outcome after surgical ASD closure in childhood shows good survival and low morbidity. Early surgical closure prevents pulmonary hypertension and reduces the occurrence of supraventricular arrhythmias. Early postoperative arrhythmias are predictive for the need for pacemaker implantation during early follow-up, but the rate of late pacemaker implantation remains low. Although RVEF was unexpectedly found to be decreased in one-third of patients, the functional status remains excellent.

Major adverse cardiovascular events in adult congenital heart disease: a population-based follow-up study from Taiwan
Conclusions:
After a median of 11 years of follow-up, the Taiwanese patients with ConHD were at an increased risk of life-long cardiovascular MACE, including heart failure, stroke, acute coronary syndrome, and malignant dysrhythmia. Surgical correction may help to decrease long-term MACE in ConHD patients, especially those with ASD.

HeartStitch touts new PFO closure method
Structural heart focused HeartStitch said today its NobleStitch EL device was used to repair 3 patients with patent forman ovale heart defects in Astana, Kazakhstan.
A patent foramen ovale is a congenital heart disease in which hole in the heart that normally seals at birth remains open, and can lead to severe migraines, visual auras and stroke, the company said.
The procedures were performed by Dr. Michael Mullen and guided by Anthony Nobles at the National Research Cardiac Surgery Center in Astana, according to the company.
“We are gratified that our colleagues from abroad have brought this technology to Kazakhstan...

Quantification of Shunt Volume Through Ventricular Septal Defect by Real-Time 3-D Color Doppler Echocardiography: An Study
Quantification of shunt volume is important for ventricular septal defects (VSDs). The aim of the in vitro study described here was to test the feasibility of using real-time 3-D color Doppler echocardiography (RT3-D-CDE) to quantify shunt volume through a modeled VSD. Eight porcine heart phantoms with VSDs ranging in diameter from 3 to 25 mm were studied. Each phantom was passively driven at five different stroke volumes from 30 to 70 mL and two stroke rates, 60 and 120 strokes/min. RT3-D-CDE full volumes were obtained at color Doppler volume rates of 15, 20 and 27 volumes/s.

Atrial Septal Defects and Cardioembolic Strokes
Atrial septal defects (ASDs) can be complicated by cardioembolic strokes, but the exact incidence is unknown. Patients with large and small shunts may present with a cardioembolic stroke. Patients with cryptogenic strokes should have cardiac ultrasound to see if an ASD is present. Cardioembolic strokes associated with ASD principally occur with 2 mechanisms. The first is paradoxic embolism involving a venous-based source of thrombus, which may subsequently pass through the ASD by right-to-left shunting, causing a cardioembolic stroke. The second is atrial fibrillation that can complicate the course of patients with ASDs, e...

Paradoxical embolism: Myth or reality?
Abstract
Paradoxical embolism should be suspected in front of a clinical phenomenon of thromboembolism associated with an anatomical right-to-left shunt. Others potential cardiac sources of thromboembolism must be ruled out. Strokes constitute the most frequent clinical manifestations of paradoxical embolism. Right-to-left left shunts are in connection with intracardiac defects (atrial septal defect and patent foramen ovale) or pulmonary arteriovenous malformations. The probability that a discovered PFO is stroke-related can be evaluated by a score. Therapeutic approaches for secondary prevention of recurrent stro...

Human Fetal Hearts with Tetralogy of Fallot have Altered Fluid Dynamics and Forces.
In this study, we performed patient-specific ultrasound-based flow simulations of 3 TOF and 7 normal human fetal hearts. TOF right ventricles (RV) had smaller end-diastolic volumes (EDV) but similar stroke volumes (SV), while TOF left ventricles (LV) had similar EDV but slightly increased SV compared to normal ventricles. Simulation showed that TOF ventricles had elevated systolic intra-ventricular pressure gradient (IVPG), and required additional energy for ejection, but IVPG elevations were considered to be mild relative to arterial pressure. TOF RV and LV had similar pressures due to equalization via ventricular septal ...
