A patent foramen ovale (PFO) is found in around 25-30% of patients. The discovery is often made only on autopsy, as most PFOs are clinically silent and any inter-atrial blood exchange typically shunts from the left to right heart [1]. Thus, when a patient presents with hypoxic respiratory failure, concern for presence of a PFO is rarely at the top of the differential. However, in the setting of elevated right heart pressures, PFOs can become of great hemodynamic importance and can lead to deadly complications, including right to left shunting and refractory hypoxic respiratory failure...

A 39-year-old man with a history of sickle cell disease (SCD) presented with left leg weakness. He had a normal CT head and CT angiogram, but MRI head showed multiple acute bilateral cortical infarcts including in the right precentral gyrus. The MRI findings were more in keeping with an embolic source rather than stroke related to SCD, although it could not be ruled out. He also had an echocardiogram which revealed a patent foramen ovale. He was treated with antiplatelet therapy and also had red blood cell exchange transfusion...

BACKGROUND: Transcranial Doppler echocardiography and transthoracic echocardiography may detect with high accuracy right-to-left shunt (RLS) due to patent foramen ovale (PFO). However, a standardized diagnostic protocol has never been established. It has been suggested that standing or sitting positions may improve sensitivity of transcranial Doppler due to increased LRS in such positions. We aimed to test efficacy of the sitting position in addition to the supine position in the grading of RLS in patients with PFO...

The use of atrial septal device occluders can lead to device embolization. This major complication can occur due to loose margins, deficient aorta, or thin and floppy posterior rim. Device embolization most often occurs after device release, and retrieval is essential. Many devices, including snare and bioptome, have been utilized for retrieval. However, performing these procedures can be difficult and time consuming. Failure to retrieve the embolized device requires open heart surgery. We report a novel and easy to perform method, "coronary wire trap technique," in the event of retrieval failure using conventionally available devices and snare, thereby preventing open-heart surgery...

BACKGROUND: Atrial septal defect (ASD) and patent foramen ovale (PFO) are 2 of the most common congenital heart diseases in adults and pose important risks of perioperative acute ischemic stroke (AIS) from paradoxical emboli. We evaluated the following: (1) the prevalence of ASD/PFO in the total hip arthroplasty (THA) population; (2) the rate of perioperative AIS during index admissions; and (3) the risk for perioperative AIS after THA for patients with ASD/PFO vs matched controls. METHODS: We identified 393,652 patients in the Nationwide Inpatient Sample who underwent THA between January 1, 2007, and December 31, 2013...

The case of a 24-year-old male with complaints of migraine headaches was referred for echocardiography. The rest of medical history was unremarkable. Agitated saline contrast bubble study showed evidence of a right to left intracardiac shunt, probably secondary to a patent foramen ovale. Results of a transesophageal echocardiogram suggested the possibility of an anomalous venous circulation and eventually identified as anomalous left-sided superior vena cava with cardiac magnetic resonance imaging.

We compared transcranial Doppler (TCD) with transesophageal echocardiography (TEE) and transthoracic echocardiography (TTE) for the detection of right to left communication (RLC) in the heart. All patients explored from 2013 to 2016 in a vascular medicine unit to detect RLC by TCD were included. Right to left communication was detected by TCD monitoring for microembolic signals after intravenous injection of agitated 5% glucose and air. One hundred one patients were explored for RLC by TCD, 64 by TEE (not possible in 10, bubble injection in 51), and 93 by TTE because of unexplained stroke or arterial thrombosis (51 males, 50 females, age 51...

With a high prevalence in the general population of approximately 25%, and a prevalence in the cryptogenic stroke population approaching 40%, the propensity of a patent foramen ovale (PFO) to precipitate or enable stroke, especially in young, otherwise healthy individuals, has been the subject of much debate. With proof of concept achieved via imaging modalities documenting thrombus-in-transit, and the development of minimally-invasive percutaneous approaches to closure, multiple observational studies and, more recently, several completed randomized controlled trials have sought to answer the question of when and in whom PFO closure should occur...

PURPOSE OF REVIEW: This article discusses neurologic complications that can arise from cardiac and aortic disease and dysfunction. RECENT FINDINGS: Advances in the care of patients with cardiac or aortic disease include the use of prolonged cardiac monitoring in cryptogenic stroke and the approval of the use of left atrial appendage closure devices for stroke prevention in patients with atrial fibrillation who are not candidates for anticoagulation. Continuing controversy surrounds patent foramen ovale closure, and new evidence indicates that cognitive impairment following coronary artery bypass grafting surgery may be less common than previously thought...

BACKGROUND: Percutaneous patent foramen ovale (PFO) closure has become a routine procedure and was proven to be safe and feasible. In a recently published pooled analysis of randomized trials, percutaneous PFO closure was shown to more effectively reduce recurrent stroke when compared with medical therapy in patients with cryptogenic strokes. However, procedural safety and closure rate are device dependent. METHODS: We performed a propensity-score matched comparison of 28 patients undergoing percutaneous PFO closure using the Cera PFO occluder (CPO) with 28 patients who received the Amplatzer PFO occluder (APO)...

OBJECTIVES: To describe the multidisciplinary assessment of patent foramen ovale (PFO) with substantial right-to-left shunting (RLS) and medium-term follow-up after PFO closure for stroke or transient ischemic attack (TIA). BACKGROUND: PFO closure is a therapeutic option to prevent recurrent ischemic event in patients with cryptogenic stroke and TIA. The apparent lack of benefit seen in previous studies was in part due to the inclusion of patients with alternate mechanisms of stroke/TIA...

Embolization of a percutaneous patent foramen ovale (PFO) closure device is a rare but serious complication. While early, periprocedural device embolization can normally be managed with snare and percutaneous retrieval, late embolization requires a different management strategy due to inability of the device to deform to allow passage into a large caliber sheath. We present a case of asymptomatic device embolization recognized six months following implantation and discuss the challenges encountered in successfully retrieving the device...

We report the case of a 48 year old men who developed a selective impairment in famous voice recognition after ischemic stroke in right subcortical structures (lenticular nucleus and head of the caudate) and right anterior temporal lobe. He underwent fibrinolytic treatment. During the following days he progressively recovered and was discharged without neurological focal sign. Patent foramen ovale was found. When he got back to his house he noticed that he was unable to recognize the voice of his favoured singers and needed to ask who was the singer to his relatives...
