Heart with tortuous coronary arteries. In spontaneous coronary artery dissection (SCAD), the arteries in the heart (coronary arteries) may sometimes be twisted (tortuous arteries).

Coronary tortuosity, an anatomical variant, is a phenomenon often encountered during coronary angiography. 1-3 Unfortunately, the aetiology and clinical importance of coronary tortuosity are unclear. In general, atherosclerotic arteries tend to be more tortuous than others.
Toshiba's new AIP feature provides improved visualization of the coronary arteries, allowing for better decisions in difficult situations such as patients with rapid heart rates, small tortuous arteries, bariatric patients and emergency situations," said Dr.
A tortuous artery is one that twists and winds in a “tortuous” path. Tortuous arteries may be genetic or caused by other health conditions, such as thickening of the arteries or simple aging. Tortuous arteries are usually only noted when they begin to cause problems, and they pose many health risks.
Background Coronary tortuosity (CT) is a common coronary angiography finding. The exact pathogenesis, clinical implication and long-term prognosis of CT are not fully understood. The purpose of this study is to investigate the clinical characteristics of CT in patients with suspected coronary artery disease(CAD) in a Chinese population.
Tortuous coronary arteries pose a special problem for the cardiac interventionists. They are associated with difficulty in advancement of guidewire, balloons and stents across the coronaries with ...
Patients with tortuous arteries may also have tortuous veins. Tortuous arteries and veins are a common occurrence in both animals and humans, according to the National Center for Biotechnology Information. If a patient has severe tortuosity, then he may experience health issues, such as an ischemic attack in his distal organs.
Spontaneous coronary artery dissection (SCAD) can slow or block blood flow to the heart, causing a heart attack, abnormalities in heart rhythm or sudden death. Spontaneous coronary artery dissection (SCAD) most commonly affects women in their 40s and 50s, though it can occur at any age or in men.
Percutaneous intervention of tortuous coronary arteries can be challenging. We describe four cases that illustrate complications associated with coronary tortuosity (coronary dissection and stent loss) and strategies that can improve procedural success (such as use of soft delivery catheters, deep guide intubation, meticulous vessel preparation, and use of short, thin-strut stents).
NORMAL CORONARY ARTERY ANATOMY. There are two coronary arteries, the right coronary artery (RCA) and left coronary artery (LCA), which originate from their respective sinuses of Valsalva—the RCA from the right sinus of Valsalva and the LCA from the left sinus of Valsalva ().The right sinus of Valsalva is located anteriorly and the left sinus of Valsalva posteriorly and to the left.
