Abstract Background Reverse takotsubo cardiomyopathy (rTTC) is recognized as an atypical type of TTC. It has been suggested that neurological events are typical trigger of rTTC, especially in young individuals. Case summary In this case report, we describe a 16-year-girl who presented with neurological deficits due to embolic stroke and acute heart failure. Transthoracic echocardiography on admission revealed a severely reduced left ventricular (LV) function with akinesis of basal to mid LV, but normal contraction in apex. Coronary computed tomography angiography confirmed unobstructed coronary arteries. Two weeks later, her LV wall motion and ejection fraction were completely normalized. Transthoracic echocardiography and transoesophageal echocardiography demonstrated no evidence of intracardiac thrombus but showed a patent foramen ovale (PFO) with large shunt. After thorough work-up and brain–heart team discussion, we concluded that the patient developed rTTC due to cryptogenic stroke related with her PFO. She underwent percutaneous PFO closure for secondary prevention with good clinical course. Discussion Reverse TTC is a rare condition. It should be considered in stroke patients with acute heart failure. Quick diagnosis and management with brain–heart team is crucial for better prognosis.

Approximately 40% of ischemic strokes have no clearly definable etiology and are termed cryptogenic strokes. Patent foramen ovale, a small communication between the left and right atria, is considered to be a risk factor for cerebral embolism. In this study, we report the case of a 29-year-old woman with diagnosis of ischemic stroke due to patent foramen ovale who has undergone percutaneous endovascular closure. The aim of this report is to discuss the relevant aspects of the patent foramen ovale and the cryptogenic stroke, its clinical presentation, diagnosis, management and recurrence.

Abstract Transcatheter closure of patent foramen ovale (PFO) is an effective therapy for preventing cryptogenic stroke (CS). The identification of high-risk PFO, which is more likely to be linked to CS, is essential. This study aimed to assess the accuracy of contrast transthoracic echocardiography (TTE) for evaluating large right-to-left (RL) shunt. We enrolled 119 patients with or without CS who were confirmed to have PFO. The severity of RL shunt evaluated by contrast TTE and transesophageal echocardiography (TEE) was classified as follows: small (<10 microbubbles), moderate (10–20 microbubbles), and large (>20 microbubbles). With contrast TTE, large RL shunt was observed in 94 (79%) of 119 patients, including 66 of 74 with CS and 28 of 45 without CS. With contrast TEE, large RL shunt was observed in 33 (28%) patients, including 26 with CS and 7 without CS. Contrast TTE showed large RL shunt more frequently than contrast TEE (p < 0.01). Large RL shunt evaluated by contrast TTE had a sensitivity of 89% and an accuracy of 70% for the association with CS, whereas large RL shunt evaluated by contrast TEE had a sensitivity of 35% and an accuracy of 56%. Accuracy was significantly greater in contrast TTE than in contrast TEE (p = 0.02). In conclusion, contrast TTE identified large RL shunt more frequently. Large RL shunt evaluated by contrast TTE provided greater accuracy for the association with CS. Our findings suggest that contrast TTE is valuable for evaluating large RL shunt as high-risk PFO.

The correlation between cryptogenic stroke and patent foramen ovale is high in young patients. Currently, transesophageal echocardiography is the gold standard for detection. However, it is invasive and limits Valsalva maneuvers. This article reviews the diagnostic accuracy of the three modalities: transthoracic echocardiography, transesophageal echocardiography, and transcranial Doppler. The results suggest that transcranial Doppler sonography is an accurate, easily accessible procedure for detecting patent foramen ovale and should be considered an excellent alternative to transthoracic or transesophageal echocardiography. Transesophageal echocardiography is still necessary for patients who require treatment. The combination of transcranial Doppler and transesophageal echocardiography provides the highest level of information regarding the complete diagnosis of patent foramen ovales.

Background. Patent foramen ovale (PFO) has been linked to the pathophysiology of cryptogenic stroke. Contrast transesophageal echocardiography (cTEE) is the current gold standard for PFO diagnosis, but it has the disadvantage of being semi-invasive and does not exempt from risks. As a diagnostic test, the efficacy of contrast transthoracic echocardiography (cTTE) and contrast transcranial Doppler (cTCD) is controversial. This study is aimed at investigating the efficacy of cTTE and cTCD versus cTEE in PFO detection, exploring a more cost-effective and reliable method for the diagnosis of PFO related to cryptogenic stroke. Methods. From August 2019 to January 2020, a total of 213 patients with suspected PFO were included in our study. All patients underwent cTEE, cTCD, and cTTE examinations. cTTE3 was named for using a cutoff of 3 beats to detect PFO during cTTE, and cTTE5 represented a cutoff of 5 beats. A cutoff of cTCD grade III was named cTCD III. A cutoff of grade IV was named cTCD IV. cTTE3+cTCD IV was used for the combination of a cutoff of 3 beats during cTTE with grade IV of cTCD. cTTE5+cTCD III combined a cutoff of 5 beats during cTTE with cTCD grade III. Taking cTEE as the gold standard, we compared the sensitivity, specificity, negative likelihood ratio (-LR), and misdiagnosis rate for PFO detection among the above methods. Results. A total of 161 of 213 (76%) patients had PFO confirmed by cTEE. With the spontaneous Valsalva maneuver, the sensitivity, specificity, negative likelihood ratio (-LR), and misdiagnosis rate of cTTE3 in PFO diagnosis were 60%, 90%, 44%, and 10%, respectively, and those for cTTE5 were 76%, 78%, 31% and 22%, respectively. The sensitivity, specificity, negative likelihood ratio (-LR), and misdiagnosis rate of cTCD III were 80%, 71%, 29%, and 29%, respectively, while those for cTCD IV were 55%, 90%, 49%, and 10%, respectively. When cTTE and cTCD were combined to diagnose PFO, the specificity and misdiagnosis rate were significantly improved, especially cTTE3+cTCD IV, with 100% specificity and a misdiagnosis rate of 0. Conclusion. cTTE or cTCD can be used for preliminary PFO related to cryptogenic stroke findings. The combination of the two methods can improve the specificity of PFO diagnosis, especially using the cutoff of cTTE3+cTCD IV.

Introduction. Takotsubo cardiomyopathy is a relatively novel cardiac syndrome that is characterized by transient left ventricular asynergy involving apical and mid-ventricular segments. Epidemiology and pathophisiology. It occurs predominantly in elderly women in the absence of obstructive coronary artery disease and is usually associated with severe emotional or physical stress. This syndrome is manifested with chest pain, electrocardiographic changes that mimic acute myocardial infarction, and minimal myocardial enzy?matic release. Several different mechanisms have been proposed: coronary artery spasm, dynamic left ventricular outflow/intracavitary obstruction, coronary microvascular dysfunction and direct catecholamine-mediated cardiomyocite injury. Therapy and prognosis. Complete recovery usually occurs after dramatic presentation, frequently complicated with acute heart failure. Therapy is empiric and directed towards supportive measures against cardiogenic shock, acute heart failure, dysrhythmias. In-hospital mortality rate is less than 1%, but long-term prognosis is still unknown. In addition to the review of the literature on takotsubo cardiomyopathy, we present the first series of patients with this syndrome detected in Clinical Hospital Center Zemun.

AbstractTranscatheter closure of patent foramen ovale (PFO) is an effective therapy for preventing recurrent stroke in very specific patient cohorts, such as cryptogenic stroke (CS). The identification of high-risk PFO, which is more likely to be linked to CS, is essential. This study aimed to assess the accuracy of saline contrast transthoracic echocardiography (TTE) for evaluating large right-to-left (RL) shunt. We enrolled 119 patients with or without CS who were confirmed to have PFO by transesophageal echocardiography (TEE) or catheterization. The severity of RL shunt evaluated by TTE and TEE was classified as follows: small (< 10 microbubbles), moderate (10–20 microbubbles), and large (> 20 microbubbles). With TTE, large RL shunt was observed in 94 (79%) of 119 patients, including 66 of 74 with CS and 28 of 45 without CS. With TEE, large RL shunt was observed in 33 (28 %) patients, including 26 with CS and 7 without CS. TTE showed large RL shunt more frequently than TEE (p < 0.01). Large RL shunt evaluated by TTE had a sensitivity of 89 % and an accuracy of 70 % for the association with CS, whereas large RL shunt evaluated by TEE had a sensitivity of 35% and an accuracy of 56 %. Accuracy was significantly greater in TTE than in TEE (p = 0.02). In conclusion, TTE identified large RL shunt associated with CS with higher sensitivity and accuracy compared to TEE. Our findings suggest that the decision for device closure should be made based on the severity of RL shunt by TTE.
