A 50 year old woman presented with a history of angina and palpitation. She had a positive exercise test and thallium scintigraphy showed reversible ischaemia in the territory of the left anterior descending coronary artery. Coronary angiography showed a small coronary arteriovenous fistula arising from the bifurcation of the left main stem--that is, the origin of the left anterior descending and circumflex coronary arteries--with no evidence of coronary stenosis. The aberrant coronary artery was embolised with platinum microcoils delivered by a percutaneous, transcatheter, coaxial technique. The patient was subsequently symptom free with no evidence of ischaemia on exercise testing or thallium scintigraphy. This case suggests that when there is clear evidence of myocardial ischaemia even small coronary arteriovenous fistulas should be treated by embolisation.

Solid-state detector single photon emission computed tomography (SPECT) enables the acquisition of dynamic data for calculation of myocardial blood flow (MBF) and myocardial flow reserve (MFR). Here, we report about our experiences on routine clinical use and robustness using Tc-99 m-sestamibi and Tc-99 m-tetrofosmin. 307 patients underwent dynamic list-mode myocardial perfusion imaging (MPI) and standard static MPI for clinical workup of coronary artery disease on a dedicated cardiac SPECT camera.

Department of Anesthesiology, Perioperative and Pain Medicine, Icahn School of Medicine at Mount Sinai, New York, NY.

Quality improvement (QI) in medicine serves as the cornerstone of best practices. It enhances medical care by maximizing safety and efficiency while minimizing errors and waste. For a QI initiative to succeed it requires careful strategizing and effective change management plans, including the application of established QI methodologies to ensure sustainable success.

Engineered Strategies to Interfere with Macrophage Fate in Myocardial Infarction.

ACS Biomater Sci Eng

Central Laboratory, The Fifth Affiliated Hospital, Southern Medical University, Guangzhou, Guangdong 510910, China.

Myocardial infarction (MI), a severe cardiovascular condition, is typically triggered by coronary artery disease, resulting in ischemic damage and the subsequent necrosis of the myocardium. Macrophages, known for their remarkable plasticity, are capable of exhibiting a range of phenotypes and functions as they react to diverse stimuli within their local microenvironment. In recent years, there has been an increasing number of studies on the regulation of macrophage behavior based on tissue engineering strategies, and its regulatory mechanisms deserve further investigation.

Initial therapy in patients with pulmonary arterial hypertension and cardiovascular comorbidities.

Eur Respir J

January 2025

INSERM UMR_S 999 « Pulmonary Hypertension: Pathophysiology and Novel Therapies », Hôpital Marie Lannelongue, Le Plessis-Robinson, France

Background: European guidelines recommend initial monotherapy in PAH patients with cardiovascular (CV) comorbidities based on the limited of evidence for combination therapy in this growing population.

Methods: A retrospective analysis was conducted on incident PAH patients enrolled in the French Pulmonary Hypertension Registry between 2009 and 2020. Propensity score matching was used to investigate initial dual oral combination therapy oral monotherapy in patients with at least one CV comorbidity (, hypertension, obesity, diabetes and coronary artery disease).

Background: Training in complex high-risk indicated percutaneous coronary intervention (CHIP-PCI) has frequently been reserved for established operators (consultants/attending) with trainees (fellows-in-training or FIT) being often discouraged from carrying out such procedures as a primary operator due to their high-risk nature. Whether the outcomes of these cases differ if the primary operator is a supervised FIT compared with a consultant is unknown.

Methods: Using multicentre PCI data from three cardiac centres in South Wales, UK (2018-2022), we identified 2295 CHIP-PCI cases with a UK-BCIS CHIP Score of 3 or more.
