Pericardial thrombus and cardiac tamponade after pericardiocentesis with intact heart walls.

A young patient affected by a lung neoplasm, presented at emergency department with cardiac tamponade, underwent pericardiocentesis with a prompt restoration of hemodynamic stability. An hour later, the patient presented again signs of tamponade, without evidence of fluids in the drainage that was left in pericardial space. The echocardiography revealed an intrapericardial thrombus compressing the right chambers. An emergency pericardiotomy was performed and a large thrombus was removed from the pericardial space; cardiac walls were intact. Echocardiography played a pivotal role for the identification of a pericardial thrombus as a complication of pericardiocentesis.

Trans-catheter closure of a rare cause of pre-tricuspid left-to-right shunt: A "double" levoatriocardinal vein without left heart obstructive lesions.

The levoatriocardinal vein is a rare vascular anomalous connection between the left atrium and the superior vena cava (or left innominate vein). This defect is usually associated with left heart obstructive lesions, while it is rarely found in an isolated form. In the former case, the anomalous connection causes a pre-tricuspid left-to-right shunt with right-heart volume overload. We describe the first case of "double" homolateral levoatriocardinal vein in a child with signs and symptoms of right-heart failure and pulmonary blood-flow overload. A trans-catheter closure of both vascular connections was performed with two Amplatzer Vascular Plug type II (Abbott, Plymouth, MN, USA). The percutaneous approach proved to be safe and effective, with early improvement in the signs and symptoms of heart failure. .

Contemporary management of severe symptomatic bicuspid aortic valve stenosis: the BiTri Registry.

AIMS: A greater number of patients with bicuspid aortic valves (BAV) may be identified and treated as indications for transcatheter aortic valve implantation (TAVI) are expected to expand to younger patients. We evaluated the contemporary frequency and management of symptomatic patients with stenotic BAV in a multicenter European registry. METHODS: Between November 2017 and February 2018, all consecutive patients admitted for symptomatic aortic stenosis across six high-volume European hospitals were prospectively enrolled in the BiTri registry. RESULTS: Of the 832 patients, 17% (n = 138) had a BAV. The most frequent BAV phenotypes were type 1 (left--right coronary cusps fusion 64%) and type 1 (right-noncoronary cusps fusion 17%). Type 0 and type 2 accounted for 12 and 2%, respectively. When compared with tricuspid patients (n = 694), BAV patients were younger, with lower surgical risk. The transthoracic echocardiography (TTE) identified BAV in 64% of patients. Multisliced computed tomography (MSCT) additionally completed the diagnosis in 20% of patients. Surgical inspection finally identified the remaining undiagnosed 16% of BAV. A combination of TTE and MSCT was the most common diagnosis method for BAV. Surgical aortic valve replacement (SAVR) was the predominant therapeutic option for BAV (70%) whilst TAVI was performed in 26%. CONCLUSION: BAV is frequently observed in symptomatic patients with aortic stenosis. These patients are younger, have a lower risk profile and are predominantly treated with SAVR as compared with tricuspid patients. However, TAVI is performed in almost one-third of BAV patients in contemporary European practice. TTE combined with MSCT identified 84% of BAV.

Epicardial Adipose Tissue and IL-13 Response to Myocardial Injury Drives Left Ventricular Remodeling After ST Elevation Myocardial Infarction.

INTRODUCTION: Left ventricular (LV) remodeling after ST-segment elevation myocardial infarction (STEMI) is explained only in part by the infarct size, and the inter-patient variability may be ascribed to different inflammatory response to myocardial injury. Epicardial adipose tissue (EAT) is a source of inflammatory mediators which directly modulates the myocardium. EAT increase is associated to several cardiovascular diseases; however, its response to myocardial injury is currently unknown. Among inflammatory mediators, IL-13 seems to play protective role in LV regeneration, but its variations after STEMI have not been described yet. Purpose: In the present study we analyzed the association between infarct-related changes of EAT and IL-13 in post-STEMI LV remodeling. METHODS: We enrolled 100 patients with STEMI undergoing primary angioplasty. At the enrolment (T0) and after 3 months (T1), we measured EAT thickness by echocardiography and circulating levels of IL-13 by ELISA. RESULTS: At T1, the 60% of patients displayed increased EAT thickness (ΔEAT > 0). ΔEAT was directly associated to LV end-diastolic volume (r = 0.42; p = 0.014), LV end-systolic volume (r = 0.42; p = 0.013) and worse LV ejection fraction (LVEF) at T1 (r = -0.44; p = 0.0094), independently of the infarct size. In the overall population IL-13 levels significantly decreased at T1 (p = 0.0002). The ΔIL-13 was directly associated to ΔLVEF (r = 0.42; p = 0.017) and inversely related to ΔEAT (r = -0.51; p = 0.022), thus suggesting a protective role for IL-13. CONCLUSION: The variability of STEMI-induced "inflammatory response" may be associated to the post-infarct LV remodeling. ΔEAT thickness and ΔIL-13 levels could be novel prognostic markers in STEMI patients.
