Outcomes in Catheter Ablation of Sustained Ventricular Tachycardia in Myocarditis Compared with Ischemic Heart Disease.
Rev Cardiovasc Med
January 2025
Arrhythmia Center, Fuwai Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College, National Center for Cardiovascular Diseases, 100037 Beijing, China.
Background: The substrates for arrhythmias in myocarditis and ischemic heart disease (IHD) are different, but it is yet to be determined whether there is a difference in outcomes following catheter ablation (CA) for ventricular tachycardia (VT) associated with these two conditions. This study aimed to compare outcomes after CA of VT in patients with myocarditis versus those with IHD.
Methods: Patients undergoing CA for sustained VT confirmed by endomyocardial biopsy as myocarditis, and patients with IHD experiencing sustained VT undergoing CA were retrospectively enrolled from February 2017 to March 2023.
[Cardiac myxoma: biological features, morphology, differential diagnosis].

Cardiac myxoma in its morphology is a typical benign tumor, meanwhile, the fact of its localization in the heart chamber, directly in the constant blood flow, largely determines the clinical behavior of this neoplasm, which is often manifested by the development of characteristics that formally determine the aggressive and even malignant nature of the course. Accordingly, the malignancy of cardiac myxoma is determined more by its clinical behavior (recurrence, multifocality of the lesion, the presence of mechanisms of spread similar to metastasis) rather than by its histological picture. In the structure of primary benign tumors of the heart, myxoma occupies a dominant position and its incidence is up to 85%.

Article Synopsis
- The study explores using multi-phase Computed Tomography Angiography (mpCTA) for better assessing cardiac health before transcatheter aortic valve replacement (TAVR) and predicting patient outcomes.
- Researchers analyzed mpCTAs from 205 patients and found that 96% could be assessed, with specific deformation measurements indicating higher risks of complications like heart failure or death.
- The findings suggest that advanced 4D modeling techniques can predict outcomes post-TAVR effectively, and further validation in multiple centers is planned.
Cervical cancer with patent foramen ovale metastasis to the left ventricle: a case report.
World J Surg Oncol

Division of Cardiology, Department of Internal Medicine, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430030, Hubei, China.
Background: Metastasis of malignant tumors to the cardiac endocardium is rare and mainly involves the right side of the heart. It is extremely rare to involve the left cardiac endocardium, especially when there is neither pulmonary metastasis nor primary lung cancer, which we call "isolated" left cardiac endocardium metastasis in this paper. Few such cases previously reported in the literature were not screened for patent foramen ovale (PFO).

Department of Cardiology, Memorial Healthcare System, Florida, USA.
Background: Cardiac papillary fibroelastomas (CPFs) are benign endocardial tumours with embolic potential. This article is a systematic review to identify the clinical profile, diagnosis, tumour characteristics, and treatment modalities in patients with CPF presenting with stroke or transient ischemic attack (TIA).
Methods: This systematic review was conducted using the PubMed and Embase databases, including case reports and/or series and observational studies (for a search period of up until April 2022).
