The clinical, ECG, echocardiographic, and angiographic data, as well as the operative findings and postoperative courses of three children with intramural ventricular tumors are presented. In all three children, the specific diagnosis of intramural tumor was unsuspected. The ECGs showed a superior axis in all patients. M-mode echocardiography missed the mass in one patient and was nonspecific in the other two; however, two-dimensional echo (2DE) was able to accurately delineate the tumors preoperatively in all three. Angiographic findings were nonspecific, only demonstrating the presence of space-occupying lesions. All three patients underwent surgery and the tumors were removed successfully. This investigation emphasizes the clinical picture that led to the diagnostic evaluations, and demonstrates the usefulness of 2DE in accurately diagnosing the intramural ventricular tumors. In addition, the sequential ECGs and 2DEs after removal of the tumors are delineated as well as showing the resolution of the tumor craters by 2DE examinations.

Impella versus Non-Impella for Non-emergent High-Risk Percutaneous Coronary Intervention: Impella vs. Non-Impella for HR-PCI.
Am J Cardiol
January 2025
Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, DC, USA. Electronic address:
Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).

Objective: To evaluate the effect of rescuer team size on objective skill measures of basic life support (BLS) and advanced life support (ALS) using high-fidelity canine CPR simulation.
Design: Prospective, experimental study.
Setting: Veterinary clinical simulation center.
Relationship between left ventricular shape and cardiovascular risk factors: comparison between the Multi-Ethnic Study of Atherosclerosis and UK Biobank.

January 2025
Biomedical Engineering & Imaging Sciences, Faculty of Life Sciences & Medicine, King's College London, London, UK
Background: Statistical shape atlases have been used in large-cohort studies to investigate relationships between heart shape and risk factors. The generalisability of these relationships between cohorts is unknown. The aims of this study were to compare left ventricular (LV) shapes in patients with differing cardiovascular risk factor profiles from two cohorts and to investigate whether LV shape scores generated with respect to a reference cohort can be directly used to study shape differences in another cohort.

JACC Clin Electrophysiol
January 2025
Section of Cardiac Pacing and Electrophysiology, Division of Cardiology, Cleveland Clinic, Cleveland, Ohio, USA.
Background: In patients with mechanical aortic and mitral valves requiring catheter ablation of ventricular tachycardia (VT), a technique for access from the right atrium (RA) to the left ventricle (LV) via puncture of the inferoseptal process of the LV was previously described in a single-center series.
Objectives: This study sought to report the multicenter experience of VT ablation using this novel LV access approach.
Methods: We assembled a multicenter registry of patients with double mechanical valves who underwent VT ablation with RA-to-LV access.
Hybrid Repair of Ascending Aortic Intramural Hematoma and Arch Ulcer in a 74-Year-Old Woman - A Case Report.

BACKGROUND Acute intramural hematoma (IMH) of the ascending thoracic aorta and aortic arch is a life-threatening condition, particularly in elderly patients with comorbidities, due to its risk of progression and rupture. Unlike aortic dissection, IMH lacks an intimal tear, influencing both clinical presentation and treatment strategy. This report describes a 74-year-old hypertensive woman with type A IMH and a penetrating atherosclerotic ulcer (PAU), managed with a hybrid surgical approach that combines external Dacron wrapping of the ascending aorta and endovascular stenting of the aortic arch with in-situ fenestration of the supra-aortic arteries.
