2024年2月6日 · Ramus circumflex artery (RCx) The circumflex artery (Cx) is one of the two major coronary arteries that arise from the bifurcation of the left main coronary artery (the other branch being the left anterior descending (LAD) artery ).

2025年3月1日 · Their findings highlighted two predominant variants: the RCA originating from LMCA, and the RCx originating from the RSV, with prevalence rates of 0.49 % and 0.36 %, respectively. The RCx can either join the opening of the RCA, emerge as a branch near the beginning of the RCA, or have its own distinct opening within the RSV. 27. e.

Retro-commissioning (RCx) is a systematic process to improve how equipment and systems function together in an existing building. RCx can often resolve problems that occurred during building start up or address problems that have evolved throughout the building’s life.

The C2117 Connecticut RCx Persistence Study Measure Life/EUL Update Study involves the update of the effective useful life (EUL) values for key retro-commissioning (RCx) measures offered through Connecticut’s energy efficiency programs. The objectives of this study were to

One variant of AAOCA is the anomalous origin of the left circumflex artery from the right sinus of Valsalva, which can be detected using cardiac computed tomography (CT). However, limited data are available regarding the natural history of this anomaly, its impact on myocardial function, and associated symptoms.

2008年10月14日 · In 15% of cases a third branch arises in between the LAD and the Cx, known as the ramus intermedius or intermediate branch. This intermediate branche behaves as a diagonal branch of the Cx. The LAD travels in the anterior interventricular groove and continues up to the apex of the heart.

2023年11月22日 · RCx was defined as a circumflex artery originating from the right sinus of Valsalva (type I or II) or the right coronary artery (type III). Two researchers independently reevaluated each CT exam in our study group to ensure accurate radiologic descriptions and provide additional precise radiologic information regarding the anomaly, including ...

2018年5月1日 · We found a good to excellent agreement for CAC risk, comparing standard dose and ultra-low dose CT with readers reporting identical risk in 81%. Our findings suggest that prognostically valuable information can and should be obtained from ungated ultra-low chest CT.

Retro-Commissioning (RCx), sometimes referred to as Existing Building Commissioning (EBCx), is an important process for optimizing the performance of existing buildings. It involves the comprehensive evaluation of a building’s systems, their …

2023年1月12日 · Abkürzung für die linke Herzkranzarterie, die sich bereits früh im oberen Bereich des Herzens in zwei wichtige Äste, den Ramus interventricularis anterior (RIVA, LAD) und den Ramus circumflexus (RCX, LCx) teilt.
