Acute decompensated right heart failure potentially triggered by multiple factors including pulmonary vasodilator removal during plasma exchange: a case report.
JA Clin Rep
January 2025
Department of Anesthesiology and Critical Care Medicine, Hokkaido University Hospital, N14W5, Kita-ku, Sapporo, 060-8648, Japan.
Background: Plasma exchange (PE) removes high-molecular-weight substances and is sometimes used for antineutrophil cytoplasmic antibody-associated vasculitis (AAV) with alveolar hemorrhage. Hypotension during PE is rare, except in allergic cases. We report a case of shock likely caused by increased pulmonary vascular resistance (PVR) during PE.

Sleep Breath
January 2025
Department of Cardiac and Vascular Diseases, Jagiellonian University Medical College, John Paul II Hospital, Prądnicka 80, Kraków, 31-202, Poland.
Background: Obstructive sleep apnoea (OSA) may lead to heart rhythm abnormalities including bradycardia. Our aim was to ascertain clinical and echocardiographic parameters in patients with OSA in whom severe bradycardia was detected in an outpatient setting, as well as to evaluate the efficacy of CPAP therapy on heart rate normalization at the early stages of treatment.
Methods: Fifteen patients mild, moderate or severe OSA and concomitant bradycardia were enrolled.
Background: RING finger protein 213 () p.R4810K is an established risk factor for moyamoya disease and intracranial artery stenosis in East Asian people. Recent evidence suggests its potential association with extracranial cardiovascular diseases, including pulmonary hypertension.

Eur J Radiol Open
June 2025
Department of Radiology, Shanghai Children's Medical Center, Shanghai Jiao Tong University School of Medicine, 1678 Dong Fang Road, Shanghai 200127, PR China.
Background: The Fontan procedure is a surgical intervention designed for patients with single ventricle physiology, wherein the systemic venous return is redirected into the pulmonary circulation, thereby facilitating passive pulmonary blood flow without the assistance of ventricular propulsion. Consequently, long-term follow-up of individuals who have undergone the asymptomatic Fontan procedure is essential.
Objectives: The aims of this investigation were to: 1) examine the impact of flow components and kinetic energy (KE) parameters on hemodynamic disturbances in asymptomatic Fontan patients and control group; 2) Assess left ventricular diastolic dysfunction through the analysis of 4D flow parameters across different Fontan sub-groups; 3) Compare intracardiac flow parameters among Fontan sub-groups based on morphological features of the left ventricle (LV) and right ventricle (RV).
Cardiac calcified amorphous tumor as a potential cause of cerebral infarction: A clinical case report.
Radiol Case Rep
March 2025
Department of Radiology, Tenri Hospital, Nara, Japan.
We report the case of a 62-year-old male on long-term hemodialysis who was admitted to our hospital due to acute cerebral infarction associated with a cardiac calcified amorphous tumor (CAT). The patient presented with recurrent episodes of syncope and retrograde amnesia. Brain MRI identified multiple acute cerebral infarctions, while transthoracic echocardiography (TTE) revealed a 2.
