Full feature selection for estimating KAP radiation dose in coronary angiographies and percutaneous coronary interventions [PDF]

Computers in Biology and Medicine (2020): 103725, 2020
In interventional cardiology (IC) the radiation dose variation is very significant, and its estimation has been difficult due to the complexity of the treatments. In order to tackle this problem, the aim of this study was to identify the most important demographic and clinical features to estimate Kerma-Area Product (KAP) radiation dose in coronary ...

Long‐term outcomes after paclitaxel‐coated balloon angioplasty of femoropopliteal arteries in Asian patients of the IN.PACT Global Study

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1273-1283, December 1, 2022., 2022
Abstract Objectives The long‐term data on the use of drug‐coated balloons (DCBs) for femoropopliteal atherosclerotic lesions in the real‐world setting are limited, even more so for racially and geographically distinct populations. The present analysis reports the 5‐year safety and effectiveness outcomes of a DCB in the Asian subset of the prospective ...

Evaluation of factors associated with selection for coronary angiography and in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest without ST‐segment elevation

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1159-1170, December 1, 2022., 2022
Abstract Background Clinical factors favouring coronary angiography (CA) selection and variables associated with in‐hospital mortality among patients presenting with out‐of‐hospital cardiac arrest (OHCA) without ST‐segment elevation (STE) remain unclear.

Age‐related changes in the coronary microcirculation influencing the diagnostic performance of invasive pressure‐based indices and long‐term patient prognosis

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1195-1205, December 1, 2022., 2022
Abstract Objectives Investigate age‐related changes in coronary microvascular function, its effect on hyperemic and non‐hyperemic indices of stenosis relevance, and its prognostic implications. Background Evidence assessing the effect of age on fractional flow reserve (FFR), resting mean distal intracoronary pressure/mean aortic pressure (Pd/Pa), and ...

Underweight and obesity are related to higher mortality in patients undergoing coronary angiography: The KARDIO invasive cardiology register study

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1242-1251, December 1, 2022., 2022
Abstract Background In patients with some cardiovascular disease conditions, slightly elevated body mass index (BMI) is associated with a lower mortality risk (termed “obesity paradox”). It is uncertain, however, if this obesity paradox exists in patients who have had invasive cardiology procedures.

Deep reinforcement learning for guidewire navigation in coronary artery phantom [PDF]

, 2021
In percutaneous intervention for treatment of coronary plaques, guidewire navigation is a primary procedure for stent delivery. Steering a flexible guidewire within coronary arteries requires considerable training, and the non-linearity between the control operation and the movement of the guidewire makes precise manipulation difficult.

Correlation of aortic valve annular plane assessment by on‐table three‐dimensional rotational angiography and preprocedural computed tomography

Catheterization and Cardiovascular Interventions, Volume 100, Issue 7, Page 1316-1322, December 1, 2022., 2022
Abstract Objectives To assess the correlation between the aortic valve annular plane (AVAP) obtained by preprocedural computed tomography (CT) with on‐table three‐dimensional rotational angiography (3DRA), in patients undergoing transcatheter aortic valve replacement (TAVR).

Percutaneous coronary intervention versus coronary-artery bypass grafting for severe coronary artery disease.

New England Journal of Medicine, 2009
BACKGROUND Percutaneous coronary intervention (PCI) involving drug-eluting stents is increasingly used to treat complex coronary artery disease, although coronary-artery bypass grafting (CABG) has been the treatment of choice historically.

Collateral donor artery physiology and the influence of a chronic total occlusion on fractional flow reserve [PDF]

, 2015
Background— The presence of a concomitant chronic total coronary occlusion (CTO) and a large collateral contribution might alter the fractional flow reserve (FFR) of an interrogated vessel, rendering the FFR unreliable at predicting ischemia should the ...

Drug-eluting balloon: is it useful?

The Egyptian Heart Journal, 2020
Background Coronary artery disease is one of the major issues in the medical world around the globe. The prevalence tends to increase. The use of coronary intervention is one of the ways often used in the management of coronary artery disease due to its ...
