Epicardial collateral perforation is a serious complication of retrograde chronic total occlusion percutaneous coronary intervention. We describe two cases of epicardial collateral perforation that were successfully sealed with local thrombin injection.

Intercoronary communication: a rare coronary anomaly.
Egypt Heart J
October 2024
All India Institute of Medical Sciences, Nagpur, India.
Article Synopsis
- Intercoronary communication (ICC) is a rare coronary artery anomaly that occurs in only 0.002% of patients undergoing angiography, highlighting the need for clinical awareness.
- A case study details a 56-year-old woman who experienced chest pain and was diagnosed with acute coronary syndrome; angiography revealed a significant stenosis and the existence of ICC, which connected two coronary arteries.
- The study concludes that it's important to differentiate ICC from collaterals, as they have distinct anatomical characteristics and flow patterns, with collaterals usually forming due to obstructive disease.
Efficacy of balloon-expandable extreme-low-temperature ventricular epicardial cryoablation: A preclinical proof of concept evaluation.

Article Synopsis
- Current epicardial ablation methods struggle to create deep lesions and can damage nearby structures, motivating the study of a new cryoablation catheter designed to address these issues.
- The study involved ten healthy pigs, where researchers used both surgical and percutaneous approaches to create epicardial lesions while measuring the effectiveness and safety of a low-temperature cryoablation system called HeartPad.
- Results showed that lesion depth increased significantly with longer exposure times, suggesting that the new catheter design may improve ablation outcomes while potentially protecting surrounding tissues.
The Effect of CD31 on Coronary Collateral Development.

Department of Biochemistry, Faculty of Medicine, Harran University, Sanliurfa, Turkiye.
Background: Coronary collaterals are the feeding bridges between the main epicardial arteries, and research has shown that this collateral development plays a crucial role in myocardial performance, especially in patients with coronary artery disease. However, the evolution of these collaterals has not been fully explained.
Objective: In this study, we aimed to reveal the effect of CD31 on coronary collateral development.

Background: Pulsed Field Ablation (PFA) has recently been proposed as a non-thermal energy to treat atrial fibrillation by selective ablation of ganglionated plexi (GP) embedded in epicardial fat. While some of PFA-technologies use an endocardial approach, others use epicardial access with promising pre-clinical results. However, as each technology uses a different and sometimes proprietary pulse application protocol, the comparation between endocardial vs.
View Article and Find Full Text PDFBackground: Coronary collateral circulation (CCC) can effectively improve myocardial blood supply to the area of CTO (chronic total coronary occlusion) and can, thus, improve the prognosis of patients with stable coronary syndrome (SCS). The degree of inflammation and some inflammation markers were associated with the development of collaterals.
Objective: To investigate whether prognostic nutritional index (PNI) has an association with the development of CCC in patients with SCS.
