In the present study, there was a lower prevalence of dual aortic origin, whereas the prevalence of 2 orifices within the right cusp was similar to that reported previously [ 710 ]. GómezL.

Sudden unexpected death as a result of anomalous origin of the right coronary artery from the left sinus of valsalva. J Anat ,

Anatomic variations in orifices, courses, branching patterns, and abnormalities of coronary arteries could affect blood supply, hemodynamic characteristics, and clinical symptoms, and could be a risk of atherosclerosis. To investigate the location and number of both coronary orifices in the aortic cusps, branching patterns of left main trunk, dominant pattern of predator prey relationship in the tundra interventricular artery PIAprevalence of right posterior diagonal what is the difference between right dominant and left dominant coronary circulation RPDAmyocardial bridge, and other abnormalities.

We dissected 95 heart specimens from cadavers of Thai donors without the history of surgery, and the dominant patterns, location and number of orifices in the aortic cusps, branching patterns, origin and number of conal arteries, and occurrence of RPDA were determined. Dual aortic origin of the coronary orifice was the most common condition. Anomalous 2 orifices in the left aortic cusp were found in one specimen in which the right coronary artery RCA arose from aortic cusp and had an interarterial course.

Right dominance and trifurcated form of left main trunk were found more frequently. Most frequently 2 conal arteries were found. The prevalence of right dominance, RPDA, the atypical origin of RCA from the left sinus, and the prevalence of myocardial bridges was more frequent than reported by others, whereas the dual aortic origin from both cusps and the prevalence of bifurcated left main trunk was less frequent.

The number of patients with cardiovascular disease has increased every year. Cardiovascular diseases are a leading cause of death worldwide [ 1 ]. In Thailand, the incidence of ischemic heart disease has increased every year [ 2 ]. Knowledge of anatomical pattern, variations, and anomalies of coronary arteries what is the difference between right dominant and left dominant coronary circulation important for the proper interpretation of coronary angiographies and revascularization procedures.

The left coronary artery LCA continues into the coronary sulcus. It is also known as left main trunk before bifurcating into anterior interventricular artery AIA and circumflex artery CxA. The additional branch that can be found between 2 arteries as a variation is the median artery MA. The RCA it, travels down the coronary sulcus and gives off the sinoatrial node artery. However, the conal artery can be noticed as a variation near its origin.

The RCA might give off the right posterior diagonal artery RPDA as a variation before it continues to the posterior interventricular sulcus as the posterior interventricular artery PIA. Anatomic variations in orifices, courses, branching patterns, and abnormalities of coronary arteries, which have been reported in previous studies could affect blood supply, hemodynamic characteristics, and clinical symptoms and could be a risk of atherosclerosis [ 3 ]. However, various populations in those studies lead to varieties of coronary artery information.

To our knowledge, there is no cadaveric report of the anatomic variation in the Thai population. This descriptive study intended to investigate what is the difference between right dominant and left dominant coronary circulation location and number of both coronary orifices in the aortic cusps, branching patterns of coronary arteries, dominant pattern, prevalence of RPDA, myocardial bridge, and others abnormalities in the Thai population.

The expected benefit is to provide a database of coronary arteries for coronary angiography. After dissection, the dominant patterns were determined by observing the origin of the PIA. We identified the location and number of orifices in the aortic cusps, branching patterns of the LCA, origin and number of conal arteries from the RCA, the occurrence of RPDA and its origin. Abnormalities of coronary arteries were classified according to Angelini et al.

The prevalence of normal coronary artery variations is summarized in Table 1. The right dominance was the most common type of the coronary arterial system. One coronary orifice in each aortic cusp dual aortic origin was the most common. The most frequent variation was one in the left aortic cusp and 2 in the right aortic cusp. The extra orifice in the right cusp was noted as the origin of the conal artery Figure 2. A Right dominance. B Codominance. C Left dominance. A Two orifices in the right cusp.

B Three orifices in the right cusp. Extra orifice arrow aside from RCA open arrow was conal artery. RCA, right coronary artery. The data of branching patterns of the LCA were collected from 93 specimens, because 2 were incomplete due to student dissection. The most common type was trifurcation. MA was the additional branch. In all specimens, the first branch of the RCA was the conal artery. A One conal artery from the aorta. B Two conal arteries, one from aorta 1 and another from RCA 2.

C Three conal arteries, one from aorta 22 from RCA 1, 3. Most of the RPDA occurred in a right dominant pattern. The prevalence of abnormalities of coronary arteries including the anomalous origin of RCA from the left aortic cusp Figure 5Aand the myocardial bridge are summarized in Table 2. The RCA in this anomalous case coursed interarterially between the aorta and the pulmonary trunk to continue into the coronary sulcus Figure 5B.

Most bridges comprised ventricular myocardium except one that was the right atrial wall Figure 6. In these cases, after giving the right marginal artery, the RCA traveled into the right atrium wall above the coronary sulcus and emerged from the atrial wall to terminate in the right ventricle before reaching the posterior what does the big book say about fear sulcus.

The number of myocardial bridges in each specimen ranged from 1 to 4. What is the difference between right dominant and left dominant coronary circulation most common location of the myocardial bridge was situated at the AIA. The locations and number of myocardial bridges are shown in Table 2 and Figure 7. A Myocardial loop.

B Left dominant pattern in this case. A One site of the myocardial bridge on the AIA. B Two sites on the AIA. AIA, anterior interventricular artery. Identification of the dominant pattern of coronary arteries has clinical importance particularly from the functional impact of myocardial ischemia [ 3 ]. In the present study, the prevalence of right dominance was slightly higher than that reported previously, but whats a casual relationship reddit and codominance were considered to be lower.

However, the codominant type was reported to be absent [ 6 ]. The inconsistency could be explained by the definition of the codominant type [ 7 ]. Moreover, dissection might not always yield the same result as radiology when evaluating the anatomy of the coronary artery [ 3 ]. In However, additional orifices can be found in the right aortic cusp. In the present study, there was a lower prevalence of dual aortic origin, whereas the prevalence of 2 orifices within the right cusp was similar to that reported previously [ 710 ].

Moreover, the occurrence of 3 orifices in the right cusp was higher [ 7 ]. The presence of multiple orifices might cause problem and should be considered while performing the right ventriculotomy [ 7 ]. Eventually, the trunk might be terminated by trifurcation in 6. In the present study, the prevalence of bifurcation was lower. Conversely, there were high percentages of trifurcation and quadrifurcation.

The uncertain definition of the MA could explain these different percentages. Angelini et al. It may originate from the left main trunk, or proximal part of the AIA or the CxA [ 5 ], whereas some authors [ 6716 ] as well as ourselves defined the origin of MA as only from the left main trunk. However, this artery could cause a problem while inserting a catheter and could lead to misdiagnosis [ 7 ].

The conal artery is an important in collateral circulation between the right and left coronary arteries [ 17 ]. It supplies the conus arteriosus and anterior, middle, and superior part of the ventricle [ 18 ]. In the present study, the prevalence and origin of conal artery were similar to those reported previously.

This artery irrigated the inferior part of the posterior interventricular sulcus and adjacent areas. The prevalence of RPDA was Moreover, Ortale et al. The RPDA was found in both the right and codominant types. The anomalies of coronary arteries that have hemodynamically significance are abnormalities of the origin from the opposite sinus or pulmonary artery, myocardial bridge, and coronary fistula [ 21 ].

These might be involved life-threatening symptoms; arrhythmia, myocardial infarction, or sudden death [ 7 ]. The atypical origin of the RCA from the left sinus and from the pulmonary artery what do you mean by dominant trait considered to be malignantly anomalous.

It has been proven that a decrease in coronary artery circulation might produce acute myocardial ischemia, arrhythmia, and sudden death [ 22 ]. This reduction in blood flow might be caused by an acute takeoff angle from the origin and the pressure effect what is the difference between right dominant and left dominant coronary circulation the interatrial course [ 23 ]. The prevalence of anomalous origin of the RCA from left sinus was observed to be 0. The myocardial bridge comprises myocardial fibers that spread over a segment of coronary arterial branch.

The bridge was determined as an atypical course that produces compression of vessels during systole. Although it may be asymptomatic in most patients during a functional stress test, a myocardial bridge might be associated with atypical angina, especially in cases with a long and deep segment [ 2425 what is the difference between right dominant and left dominant coronary circulation. The prevalence of the myocardial bridge in angiography was 0. Occasionally, a myocardial bridge was found at more than one site.

The prevalence of single, double and triple sites of myocardial bridge were The middle third of the AIA followed by the left marginal artery were observed to be the most common locations [ 815 ]. In the present study, the prevalence resembled that reported at autopsy. In addition, a myocardial loop formed by the atrial myocardium on the RCA was found in one specimen. This abnormality had a minimal effect on the coronary diameter. Therefore, to our knowledge prevalence of the loop has not been mentioned in any literature [ 25 ].
