Oregon study: Minor heart feature may mean trouble at high altitude

(University of Oregon) A common heart feature long thought to have negligible effects on human health and performance may be problematic at high altitude. That's a key finding from a University of Oregon study that looked at the effects of a condition known as patent foramen ovale in a high-altitude Bolivian setting.

We presented twenty-four cases which also had postnatal echocardiographic examination in our hospital. A t the time of diagnosis of ASP, the mean maternal age was 31.1 ± 5.7 years, the mean gestational age was 28.9 ± 5.9 weeks, the mean birth week was 37.4 ± 3.1 weeks, and the mean birth weight was 2940.8 ± 736.6 g. The postnatal first 3 months prevalences of atrial septal ane urysm, patent foramen ovale and, secundum atrial septal defect (ASD) were 12.5%, 12.5%, 20.8% among fetuses with ASP, respectively. ASP ...

AbstractHigh-risk PE can be complicated by the presence of a patent foramen ovale (PFO), which can lead to paradoxical systemic embolization, including cerebral embolism ultimately leading to acute ischemic stroke (AIS). Acute management is challenging given the competing benefits and risks of systemic thrombolysis. Herein, we aim to provide a review of clinical presentations, diagnostic findings, and treatment and outcome from the available literature, with the hopes of providing insight into treatment options. We followed the guidelines outlined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (P...

IN THIS issue of the Journal of Cardiothoracic and Vascular Anesthesia, Villablanca et al. evaluated whether the presence and diagnosis of a patent foramen ovale (PFO) or atrial septal defect (ASD) preoperatively was associated with an increase in perioperative stroke for patients undergoing noncardiac surgery.1 The authors used “big data” to describe the largest study to date of 19,659,191 hospitalizations retrieved from the Healthcare Cost and Utilization Project's National Readmission Database.

Abstract Objectives: To access the distinct values of contrast transcranial Doppler (cTCD), contrast transthoracic echocardiography (cTTE), and contrast transesophageal echocardiography (cTEE) in the diagnosis of right-to-left shunt (RLS) due to patent foramen ovale (PFO) and to define the most practical strategy for the diagnosis of PFO. Methods: 102 patients with a high clinical suspicion for PFO had simultaneous cTCD, cTTE, and cTEE performed. The agitated saline mixed with blood was used to detect right-to-left shunt (RLS). Results: In all 102 patients, the shunt was detected at rest by cTCD in 60.78...

The incidence of PFO is 2- to 3-fold higher in patients with stroke of undetermined etiology compared to the general population, a finding that implies a causative role of PFO in patients with stroke of undetermined etiology 2,3. In this context, ...

Mostafa Elhamamsy, A Aldemerdash, F Zahran, BM Bakir, Nouf A Alanazi, Yasser Abdulrahman Awadallah, Sami Ibrahim Haggag, Mahmoud Salama AlshiekhSaudi Journal of Anaesthesia 2020 14(2):217-220 Persistent left superior vena cava (PLSVC) is a rare and asymptomatic congenital cardiovascular anomaly. Being asymptomatic, PLSVC was usually discovered while performing interventions (such as insertion of central lines, Swan-Ganz catheters, or placing pacemakers) through the left internal jugular vein or left subclavian veins. Commonly, PLSVC is detected not only as an isolated congenital anomaly, but also it can be associated with...

Conclusion The presence of a PFO may allow a completely fluoroless well tolerated and effective atrial fibrillation ablation. Probing the fossa ovalis looking for the PFO during the procedure is desirable, as it is not time-consuming and can potentially be done in every patient undergoing atrial fibrillation ablation.

Conclusions: Stroke management is based on evaluation of individual patient-risk factors. Evaluation and treatment is ideally directed by a vascular neurologist to ensure optimal secondary prevention, especially in cases where an underlying etiology is not identified on initial workup.
