Finger ischemia in a young lady: an unusual presentation of papillary fibroelastoma with intraventricular location.

An otherwise healthy 32-year-old woman suffered from finger ischemia. An echocardiogram and computed tomography scan revealed a mobile mass in the left ventricle that was attached to the anterior papillary muscle and did not involve the valve leaflets. The tumor was resected, and histopathology confirmed it to be a papillary fibroelastoma. Our case emphasizes the significance of a comprehensive diagnostic work-up for a peripheral ischemic lesion. This resulted in the discovery of an unusual intra-ventricular origin for a commonly benign tumor.

Differentiating typical Tako-tsubo syndrome from extensive anterior STEMI: Look behind the anterior wall.

BACKGROUND: Tako-tsubo syndrome (TTS) in its most typical form shares common features with anterior ST-segment elevation myocardial infarction (AMI) during acute presentation. Differential diagnosis between the two conditions is often challenging especially if ST-segment elevation is associated with extensive apical akinesis. METHODS: We sought to systematically analyze ECG and echocardiographic parameters including LV longitudinal strain and two new indexes: the inferior-apex ratio (IAR) and the inferior-lateral-apex ratio (ILAR), to assess if ventricular involvement may be different in TTS and AMI. RESULTS: A retrospective cohort study was conducted with two groups: patients with TTS (n = 22) and patients with extensive anterior STEMI (n = 22). Lack of ST elevation in V1 was associated with TTS with sensitivity and specificity of 86%, positive and negative predictive value of 86%. Longitudinal strain in mid inferior and mid inferior-lateral segments were more compromised in TTS: -4.3 ± 6.4% and -5.4 ± 5.4% in TTS versus -10.2 ± 5.5% and -9.9 ± 4.9% in AMI, respectively (p < .01 for all). By multivariate analysis, both longitudinal strain values, inferior-apical ratio (IAR) < 1 and inferior-lateral-apical ratio (ILAR) < 1 were independently associated with diagnosis of TTS during acute phase. CONCLUSIONS: Our results suggest that impaired contractility extending beyond apex to mid inferior and inferior-lateral walls can be easily assessed by IAR and ILAR, and these indexes facilitate non-invasive differentiation of TTS from extensive anterior STEMI.

[Percutaneous left atrial appendage closure in a patient with atrial fibrillation and Rendu-Osler-Weber disease]. / Chiusura percutanea dell'auricola sinistra in paziente con fibrillazione atriale e malattia di Rendu-Osler-Weber.

Atrial fibrillation is the most common cardiac arrhythmia worldwide and represents a major risk factor for cerebral embolic stroke. The standard therapy in the prevention of stroke is oral anticoagulation therapy (OAT). However, a considerable number of patients are unable to tolerate chronic OAT. Among these are patients with hereditary hemorrhagic telangiectasia. We present the case of a female patient affected by Rendu-Osler-Weber disease and atrial fibrillation with indication to OAT. Because of worsening bleeding episodes, this therapy was discontinued and we decided to perform percutaneous left atrial appendage occlusion (LAAO) with implantation of the WATCHMAN device (Boston Scientific). Post-procedural antithrombotic therapy with clopidogrel 75 mg/day was prematurely interrupted after 3 weeks because of significant bleeding recurrences. After 12 months, the patient is in good health, with rare episodes of minor bleeding. Echocardiography showed a well-positioned LAAO device, without thrombotic apposition. In conclusion, this case confirms that percutaneous LAAO is a valid therapeutic alternative to OAT and represents a successful strategy in high bleeding risk patients with a contraindication to OAT. By thorough assessment, a single antiplatelet therapy after device implantation and for a time-limited period might be considered, according to the latest recent evidence.
