  Nonobstructive coronary arteries on angiography are defined as the absence of obstructive CAD on angiography (i.e., no coronary artery stenosis ≥50%) in any potential infarct-related artery. This includes patients with normal coronary arteries (no stenosis >30%) or mild coronary atherosclerosis (stenosis >30% but ; 50%).   In pathologic examination the explanted heart was dilated and weighed g. The coronary arteries were normal. Prominent trabeculations and invaginations especially at left ventricular apex were found impressive (Figure 3).Cited by: 8.   Embryology. Early during heart development, the epithelial cells of the proepicardial organ migrate onto the epicardial surface of the heart tube to form subepicardial mesenchyme (1–3) ().The subepicardial mesenchymal cells, derived from the embryonic proepicardium cells, migrate into the underlying myocardium and contribute to development of Cited by: 7.   The concept that coronary arteries are pure end arteries has been disproved years ago. 1 The coronary collateral circulation (CCC) connects epicardial coronary arteries and is present in patients with and without coronary artery disease (CAD). 2,3 These collateral arteries have the potential to remodel and expand in case of an epicardial Cited by:

The theory that heart attacks begin in the heart itself - the Myogenic Theory - and not in the arteries, was developed by my father-in-law, the Brazilian cardiologist, Quintiliano H de Mesquita, who died in [1] In this article, I propose to describe the history of the myogenic theory for a public that is largely unaware of this alternative theory since its introduction in [2,3].

This is particularly noticeable in the assessment of microcirculation, an unavoidable compartment of coronary circulation that is frequently affected in acute coronary syndromes of in the presence of cardiovascular risk factors or non-coronary heart disease. In the coronary circulation, the right coronary artery (RCA) is an artery originating above the right cusp of the aortic valve, at the right aortic sinus in the travels down the right coronary sulcus, towards the crux of the heart. It branches into the posterior descending artery and the right marginal artery.

Heart: Abnormal Heart Rates For an adult, normal resting HR will be in the range of 60– bpm. Bradycardia is the condition in which resting rate drops below 60 bpm, and tachycardia is the condition in which the resting rate is above bpm. Trained athletes typically have very low . The coronary system is the network of blood vessels that nourishes the heart muscle. After birth, proper coronary blood circulation is required to support heart homeostasis, and altered coronary function frequently leads to myocardial ischemia, infarction and heart failure. The epicardium plays a pivotal role during coronary blood vessel embryonic development, contributing cells to Cited by: 6.   Cardiac troponin (cTn) is a biomarker of myocardial damage. New generations of high-sensitivity assays find circulating cTn in virtually all subjects. Multiple studies in various populations and patient groups have found higher levels of cTn to be predictive of future heart failure. The author proposes that initial myocardial damage from various mechanisms may Cited by: This updated third edition includes outstanding coverage of basic anatomy and physiology, plus the mechanisms of disease and pathologic conditions associated with each body system. Two unifying themes are integrated in this comprehensive text: the complementary nature of structure and function, and homeostasis. Homeostasis is used to show how normal structure and .

The heart is uniquely responsible for providing its own blood supply through the coronary circulation. Regulation of coronary blood flow is quite complex and, after over.

Abstract. Atherosclerosis is a pathologic process that develops in the arterial wall. Therefore the biology and imaging of the vessel wall is the cornerstone of research, diagnosis, and treatment in patients with atherosclerosis and coronary artery disease.

Figure 3: A year-old athlete with anomalous left coronary artery (LCA) arising from the right sinus of Valsalva with a short intramural course who initially underwent unroofing of the intramural segment without coronary translocation.

He presented with sudden cardiac arrest 20 months later. Fractional flow reserve in the proximal left main coronary artery at rest was (Panel A).

The occlusion of the coronary arteries commonly known as coronary artery disease (CAD) restricts the normal blood circulation required to the heart muscles, thus results in.

In coronary MVD, plaque can be diffuse, evenly distributed, or develop as blockages in the tiny coronary arteries Coronary MVD is a new concept and may be a cause of heart disease in women.

Treatment for chronic stable angina. The right coronary sulcus then passes inferiorly onto the diaphragmatic surface of the heart and traverses to the left. Clinical significance. The left coronary sulcus is often neglected in echocardiography.

As a result, normal variations and rare pathologic findings can be missed. See also. Posterior interventricular sulcusFMA: This chapter summarizes recent research on the coronary collateral circulation. The chapter is focused on clinical perspectives and importance of a well-developed coronary collateral circulation, the mechanisms of growth induced by chemical factors and a role for stem cells in the process.

Since James Herrik’s clinico-pathologic description in of a patient surviving sudden thrombotic coronary obstruction in the presence of inter-coronary anastomoses, it became evident that the collateral circulation is an important determinant of the rate and extent of myocardial cell by: 9.

In the pulmonary circulation, the blood volume, which approximates to 5 L in the average- size adult, can vary from as low as 50% of normal to as high as % of normal.

An increase in intrathoracic pressure, which impedes venous return to the right heart, can produce a tran- sient shift from the pulmonary to the systemic circulation of as. Pulmonary atresia with intact ventricular septum (PA-IVS) is a rare congenital heart defect (CHD) that accounts for book.

Coronary collaterals were evaluated in consecutive catheterized patients with unstable angina (defined as ischemic cardiac pain at rest associated with transient electrocardiographic changes).
