Atrial septal defect is one of the most common congenital heart diseases in adults. The defect often leads to volume overload in the right heart coupled with the potential risk of right heart failure and pulmonary arterial hypertension. These conditions lead to worsening in quality of life, decrease in physical capacity, and even to fatal outcomes. The main strategy for treatment of atrial septal defect is a transcatheter or surgical closure of the defect, but in patients with severe pulmonary arterial hypertension, it is recommended to manage pulmonary arterial hypertension and after that treat the defect invasively. This strategy is called “treat and repair” strategy. We present an illustrative case report of management and treatment of atrial septal defect, complicated with severe pulmonary arterial hypertension. In this case, surgical closure of the defect was contraindicated because of the high pulmonary vascular resistance. Therefore, the “treat and repair” strategy was approached. After specific medical treatment of pulmonary arterial hypertension, surgical closure of the defect was chosen and proven successful.

Background/Objectives: In cases of myocarditis, electrocardiograms (ECGs) may suggest a pattern of ST-segment elevation myocardial infarction (STEMI) or non-ST-segment elevation myocardial infarction (NSTEMI). NSTEMI patterns are less frequent in myocarditis cases, but it remains unclear if the presence of ST-segment elevation in myocarditis cases is related to a more severe condition and more damage in the myocardium. Methods: This is a retrospective study involving 38 patients admitted to hospital with myocarditis. Patients were divided into two groups: patients with ST-segment elevation (STE) patterns in the ECG (25), and patients without ST-segment elevation (non-STE) patterns (13). The data compared included results from epidemiological, laboratory, and instrumental tests. Data were analysed using IBM SPSS Statistics v26.0. A p value of <0.05 was established as the threshold for statistical significance. Results: C-reactive protein (CRP) levels were higher in the STE group (103.40 ± 82.04 mg/L vs. 43.54 ± 61.93 mg/L, p = 0.017). The left ventricle ejection fraction (LVEF) was significantly higher in the non-STE pattern group (49.71 ± 4.14 vs. 56.58 ± 3.99, p < 0.001). A lower LVEF correlates with higher TnI levels (r= −0.353, p = 0.032) and higher CRP levels (r = −0.554, p < 0.001). Lower left ventricle (LV) strain correlates with higher levels of Troponin I (TnI) (r = −0.641, p = 0.013). Conclusions: LVEFs in the STE group were lower compared to those in the non-STE pattern group. STE pattern was associated with higher CRP levels. Higher TnI levels in cases of myocarditis were associated with lower LV strain and lower LVEF; higher CRP levels also correlated with lower LVEF. Based on a 6-month echocardiographic follow-up, the prognosis of myocarditis was favourable.

Background: The HeartMate 3 (HM3) left ventricular assist device (LVAD) has demonstrated improved clinical outcomes in patients with advanced heart failure (HF). However, the influence of underlying HF etiology—ischemic cardiomyopathy (ICM) versus dilated cardiomyopathy (DCM)—on post-implantation outcomes remains insufficiently characterized. Objectives: This paper aims to evaluate early postoperative outcomes following HM3 LVAD implantation in patients with ICM versus DCM and to identify the preoperative hemodynamic and clinical predictors of early mortality and hemodynamic instability. Methods: We conducted a retrospective single-center cohort study of 30 patients who underwent HM3 LVAD implantation between 2017 and 2024. Patients were stratified by HF etiology (ICM, n = 17; DCM, n = 13), and preoperative clinical, echocardiographic, and right heart catheterization data were analyzed. The primary endpoint was 30-day postoperative survival. Secondary endpoints included postoperative hemodynamic stability and the need for vasopressor support. Results: Non-survivors (n = 13) demonstrated elevated central venous pressure (>16.5 mmHg), mean right ventricular pressure (>31.5 mmHg), and pulmonary vascular resistance (>7.5 Wood units), in addition to higher preoperative creatinine levels and longer cardiopulmonary bypass times. Vasopressor requirement postoperatively was associated with elevated pre-implant systolic pulmonary artery pressure. Conclusions: Preoperative right-sided pressures and renal dysfunction are strong predictors of early mortality following HM3 LVAD implantation. Patients with ICM exhibit greater early left ventricular recovery compared to those with DCM. These findings underscore the importance of comprehensive and personalized preoperative risk stratification—particularly in patients with DCM and pulmonary hypertension—to optimize postoperative outcomes and guide patient selection for durable LVAD support.

Background and Clinical Significance: Heart failure with reduced ejection fraction (HFrEF) and atrial fibrillation (AF) frequently coexist, creating a complex clinical interplay that exacerbates morbidity and mortality. AF can directly precipitate or worsen HFrEF through mechanisms such as tachycardia-induced cardiomyopathy, loss of atrial contribution to ventricular filling, and irregular ventricular response. The use of evidence-based therapies improves clinical outcomes in patients with HFrEF. Case Presentation: We present a clinical case of a 58-year-old man with left bundle branch block (LBBB), tachysystolic AF, and the aforementioned induced HFrEF. The patient’s medical treatment was optimized according to recent guidelines. Subsequent to the improvements in HF treatment, the patient’s echocardiographic data showed a higher left ventricle ejection fraction (LVEF); however, it remained below 35%. Moreover, tachysystolia persisted and was not sufficiently controlled with medications. Therefore, an upgrade of the pacemaker to cardiac resynchronization therapy (CRT) following the destruction of the AV node was performed to control tachysystolic AF and worsening of HF. After the treatment adjustments, the patient’s symptoms regressed, and echocardiography showed improved LVEF up to 41%. Conclusions: This case highlights the successful identification and timely application of intensive heart rate control management and heart failure induced by AF treatment.
