Point of care ultrasound detection of thrombus straddling a patent foramen ovale in a patient with acute chest syndrome
We report a case of a young woman with sickle cell disease who was hospitalized for vaso-occlusive crisis and subsequently developed worsening acute chest syndrome and stroke, discovered on point of care ultrasound to have right heart failure and a thrombus straddling a patent foramen oval. POCUS is highly specific for the detection of right heart dilation/dysfunction and should be a routine component of the assessment of acutely decompensating patients.PMID:36017251 | PMC:PMC9396226 | DOI:10.1016/j.rmcr.2022.101724

Contrast transesophageal three dimensional echocardiographic imaging for patent foramen ovale: a needful role?
We report a case of a 55-year-old male admitted for cardiogenic embolic ischemic stroke work up. A transesophageal (TE) echocardiography (E) with contrast study to rule out patent foramen ovale (PFO) was performed; two-dimensional (2D) analysis did not detect any bubbles passage during Valsalva manoeuvre in the standard 2D cross sectional planes; further real time three-dimensional (3D) TEE imaging revealed passage of bubbles in the left atrium (LA) by both real-time 3DTEE imaging and by the 2D unconventional cross-sectional planes allowed by 3DTEE imaging. Even though 2DTEE is considered to be the gold standard modality f...

Percutaneous closure of patent foramen ovale under transthoracic echocardiography guidance-midterm results.
Conclusions: In this single center study of mostly lean patients, percutaneous closure of PFO under TTE guidance as the only imaging tool appeared effective at midterm follow-up, while avoiding radiation exposure, endotracheal intubation and contrast agent use. PMID: 31372266 [PubMed]

A rare case of unruptured aneurysm of left coronary sinus of Valsalva accompanied with patent foramen ovale and atrial fibrillation detected after cardiac etiology stroke
We present a rare case of a 74 year old female with unruptured aneurysm of the left coronary sinus of Valsalva accompanied with patent foramen ovale and atrial fibrillation. This rare combination was detected during diagnostics for a cardiac etiology stroke. The left coronary sinus of Valsalva was reconstructed using an autologous pericardial patch, the left atrial appendage closed, left atrial ablation performed with cooled radiofrequency and the patent foramen ovale sutured directly. The patient was dismissed on the 12th postoperative day after having an uncomplicated postoperative course.

Patent foramen ovale and stroke in intermediate-risk pulmonary embolism.
CONCLUSIONS: PFO and related ischemic strokes are frequent in intermediate-risk pulmonary embolism. TEE is much more efficient than TTE for PFO diagnostic. Considering the high risk of intra-cranial bleeding with thrombolysis in PE, which in part may be due to haemorrhagic transformation of sub-clinical strokes, screening PFO with TEE should be considered in intermediate risk PE when a thrombolytic treatment is discussed.

Impending paradoxical embolism: Have we lost the clot?
First demonstrated on echocardiography in 1985, impending paradoxical embolism refers to a thrombus traversing an atrial septal defect, usually a patent foramen ovale (PFO) [1]. Estimates of the prevalence of PFO range from 15% to 35% but impending paradoxical embolism is rare, with fewer than 200 cases reported in the literature [2‐4]. Most cases are associated with pulmonary emboli. Elevated pulmonary and right atrial pressures may push a thrombus through a PFO into the systemic circulation, producing paradoxical systemic embolization. The high risk of cardio‐embolic stroke makes the diagnosis an emergency. Treatment...
