Generally, right ventricle infarction is accompanied by left ventricle infarction. Isolated right ventricle necrosis is rare. Among 1707 patients with 6-week-old myocardial infarction there were 2 cases with isolated right ventricle infarction. Diagnosis based on pathologic Q waves in right precordial chest wall leads, radionuclide and echocardiographic observations. In one case, diagnosis was supported by coronary angiography, too.

Background: Power-controlled radiofrequency ablation with irrigated-tip catheters has been the norm for ventricular ablation for almost 2 decades. New catheter technology has recently integrated more accurate tissue temperature sensing enabling temperature-controlled irrigated ablation. We aimed to investigate the in vivo ablation parameters and lesion formation characteristics in ventricular myocardium using a novel temperature-controlled radiofrequency catheter.

Intracardiac masses are rare and potentially life-threatening entities with diverse clinical presentations. The prompt identification of cardiac masses is critical. However, even with the advancement we have in imaging modalities, diagnosing cardiac masses remains a formidable challenge.

To evaluate myocardial synchronized exercise and clinical prognosis in patients with heart failure preserved ejection fraction (HFpEF), we utilized two-dimensional speckle tracking (2D-STI) stratified strain imaging. We retrospectively summarized 146 patients diagnosed with HFpEF in our hospital from January 2022 to January 2023. 2D-STI combined with stratified strain imaging was used to measure the overall left ventricular global longitudinal strain (LVGLS), the sub-endocardium, mid-myocardium, sub-epicardium LS of the left ventricle, as well as the basal, intermediate, and apical LS, the peak strain dispersion (PSD) and the transmural pressure difference, the postsystolic shortening (PSS), and early systolic lengthening.

Left ventricular (LV) pseudoaneurysm, a rare occurrence, develops when a ruptured ventricle is encapsulated by the pericardium or scar tissue. Unlike free intrapericardial rupture, which often results in cardiac tamponade and fatal outcome, there are instances where the cardiac rupture remains contained, forming a pseudoaneurysm and averting immediate tamponade. We describe a 43-year-old male who underwent successful surgical repair of LV rupture following inferior wall myocardial infarction that resulted in the formation of a large pseudoaneurysm.

Acute myocardial infarction-related cardiogenic shock (AMI-CS) is a severe, life-threatening condition characterised by inadequate tissue perfusion due to the heart's inability to pump blood effectively. The pathophysiology of AMI-CS usually arises from the sudden loss of myocardial contractility, leading to a decrease in cardiac output and systemic hypoperfusion. In approximately 90% of AMI-CS cases, the left ventricle is the primary site of dysfunction.
