Takotsubo cardiomyopathy: The challenging diagnosis in clinical routine

Takotsubo cardiomyopathy is rapidly reversible heart failure syndrome that usually mimics the symptoms of acute myocardial infarction with the characteristic regional wall-motion abnormalities (classically with a virtual apical ballooning caused by hypokinetic or akinetic apical or midventricular myocardium and hypercontraction of the basal segments) and absence of obstructive coronary artery disease. TC is usually associated with identifiable emotional, psychological or physical stress event and most commonly appears in postmen- opausal women. The certain pathophysiological mechanism remains unknown. However, the central hypothesis is supported by the excess of catecholamines and hyperactivity of nervous system. In the last decades the frequency of the TC diagnosis is increasing rapidly but at the initial presentation the diagnosis remains challenging due to the close similarities between TC and ST elevation myocardial infarction clinical presentations that consider TC as an important part of differential diagnosis in acute coronary syndrome

Acquired Cardiovascular Diseases in Patients with Pulmonary Hypertension Due to Congenital Heart Disease: A Case Report

Background: Advances in the diagnosis and treatment of congenital heart diseases (CHDs) have resulted in improved survival rates for CHD patients. Up to 90% of individuals with mild CHD and 40% with complex CHD now reach the age of 60. Previous studies have indicated an elevated risk of atherosclerotic cardiovascular disease (ASCVD) and associated risk factors, morbidity, and mortality in adults with congenital heart disease (ACHD). However, there were no comprehensive guidelines for the prevention and management of acquired cardiovascular diseases (CVDs) in ACHD populations until recently. Case presentation: A 55-year-old man with Eisenmenger syndrome and comorbidities (arterial hypertension, heart failure, dyslipidemia, hyperuricemia, and a history of pulmonary embolism (PE)) presented with progressive breathlessness. The electrocardiogram (ECG) revealed signs of right ventricle (RV) hypertrophy and overload, while echocardiography showed reduced RV function, RV overload, and severe pulmonary hypertension (PH) signs, and preserved left ventricle (LV) function. After ruling out a new PE episode, acute coronary syndrome (ACS) was diagnosed, and percutaneous intervention was performed within 24–48 h of admission. Conclusions: This case highlights the importance of increased awareness of acquired heart diseases in patients with pulmonary hypertension due to CHD

Changes of biventricular function after CABG surgery: does cardioplegia type matter?

Aim: we choose to evaluate, whether type of cardioplegia is an important predictor to determine biventricular function changes after CABG. Methods: 81 patients who underwent CABG surgery and matched inclusion criteria were enrolled in this study. The exclusion criteria were acute MI within 30 days, impaired systolic left ventricle function (LVEF ⩽35%), atrial fibrillation.TTE was performed for all patients and echocardiographic parameters of biventricular geometry and function were assessed before CABG surgery, first postoperative day and 6 months after surgery. Cardioplegia type was randomly chosen. First group consisted of 49 patients (60.5%) when CC was performed and the others 32 patients (39.5%) formed the second - BC group. Results: Patients' demographic characteristics were similar in both groups, except the lower rates of AH and BSA in BC group (p = 0.015, p = 0.001 respectively). Longer duration of XCT and CBP time was observed in BC group (p = 0.019 and p = 0.028). BC group patients showed more efficient right heart chambers size reduction (p = 0.001 for RV diameter; p = 0.015 for RA diameter) and better improvement of longitudinal RV function (p = 0.02 for TAPSE; p = 0.001 for RV S') 6 months after surgery when compared with CC group patients. RV global systolic function diminished in both groups postoperatively, but the reduction was higher in CC group, although the difference was significant in comparing early postoperative measurements with the late after CABG surgery (p = 0.03). Changes of LV systolic function as well as diameter of LA did not differ between groups (p = 0.165 and p = 0.279, respectively), while diastolic function improved significantly in BC group patients at the late follow-up period: E/e' decreased (p < 0.001) and e' velocity of interventricular septum augmented significantly (p < 0.001). Conclusion: BC is associated with better RV reverse remodelling [...]
