2. How do we define a Normal Coronary Artery?
“..nature and name of a specific coronary artery are assigned, not according
to the site of origin, proximal course or branches, but according to the
dependent territory..”

9. ACAOS are further characterized by 1 of 5 course subtypes as
• interarterial,
• subpulmonic (intraconal or intraseptal),
• pre-pulmonic,
• retroaortic, or retrocardiac (Central Illustration).
• Additionally, ACAOS may have an early intramural segment (within the
aortic wall), as seen in the majority of inter-arterial cases.
• Among course subtypes, the potential for SCD has been largely attributed to
an interarterial course between the aorta and pulmonary artery
10.
11. WHO WILL BECOME SYMPTOMATIC ?
TYPE OF ISCHEMIA CORONARY ANOMALY
Absence of ischemia Majority of anomalies (split RCA, ectopic RCA from
right cusp)
Episodic ischemia Anomalous origin of a coronary artery from the
opposite sinus (ACAOS); coronary artery fistulas
Obligatory ischemia Anomalous left coronary artery from the pulmonary
artery (ALCAPA)
Modified from Angelini P (ed): Coronary Artery Anomalies: A Comprehensive Approach. Philadelphia, Lippincott Williams &
Wilkins, 1999, p 42.
12. Anomalous origin of a coronary artery from the opposite sinus (ACAOS)
a. RCA from left anterior sinus 0.92%
b. LAD from right anterior sinus
c. LCx from right anterior sinus 0.67%
d. LCA from right anterior sinus 0.15%
• ARCA~ 6 times more prevalent than ALCA
• ALCA has a higher risk of SCD

• N = 5120 patients
Judkin catheter -Type 1.
Amplatz catheter -Type 2, and
MP catheter was useful in Type 3 origin.
For Type 4, no specific catheter is useful
JL in Type A, FCL (femoral curved left) 3,3.5 for Type B,
Voda left for Type C, and AL-1,2 for Type D.
Judkin catheter was useful in normal and low take-off
origin.
AL catheters are helpful in high take-off cases. The have
used EBU or AL catheter in few cases.
26. Tiger catheter from femoral route in these cases.
Advantage of this catheter is that it can take different
shapes by push, pull, torque, and rotation.
Its tip is also very soft and there is less chance of
dissection.
27. HOWTO IMPROVE SUPPORT ?
• TWO WIRES
• BALLOON ANCHORAGE
• UNDERSIZED GUIDE CATHETER
• STEAM DEFORMATION AND UNDERSIZING
• SPECIAL CATHETERS
28. TwoWires
Stabilizing a guide with the “buddy” wire technique
• When working with an unstable guide, a second angioplasty wire can be
advanced parallel to the first one.
• It straightens the tortuous vessel and provides better support for device
tracking.
• A second wire in a side branch can be very useful in “anchoring” the guide (e.g.
second wire in the LCX when dilating an LAD lesion).
• This provides for better “backup” and allows retraction of the guide when
necessary, without loss of position.

43. “..anomalous coronaries are more likely to be encountered as
the culprit infarct-related artery in the hemodynamically
unstable patient.”
“A key determinant to proceed with percutaneous or surgical
revascularization depends on demonstration of the origin and
course of the anomalous coronary and the hemodynamic and
general clinical status of the patient.”
“Application of the “dot and eye” method can be useful to
choose the most appropriate revascularization strategy.”

51. SPLIT RCA (1.23%)
• Split RCA is defined as an RCA that features a
split posterior descending branch
• Anterior subdivision leading to the distal portion
of the PDA and supplies distal portion of posterior
septum, inferior wall of LV and anterior free wall
of RV
• Posterior subdivision maintains a course in the AV
groove and forms the uppermost portion of the
PDA, supplying the proximal (basal) posterior
interventricular septum
• The length of each of the 2 posterior descending
branches varies from patient to patient

56. High take-off RCA (0.202%)
Defined as RCA that arises at least 1 cm above the sino-tubular junction (Vlodaver et al., 1975; Loukas et al., 2009b)
57. When the right coronary ostium is very high, the
left Amplatz guide may be used to engage the
right ostium.
58. Shepherd’s Crook RCA (4.9%)
• Shepherd’s crook deformity of the RCA is a dramatic upturn with a near-180° switchback
turn.
• It is a haemodynamically non-significant course anomaly

60. Dual LAD (0.13%)
• Dual LAD consists of a short LAD that ends high in the AIVG and a long LAD that most
commonly originates as an early branch of the LAD proper (types 1–3) and rarely originates
anomalously from the right coronary artery (type 4).
• Proposed originally by Spindola in 1983
• He classified it into 4 types
• In recent years the dual LAD has increased from 4 to 6 types.

• The LMCA was absent in 9.6%

66. Single Coronary Artery (SCA) (0.05%)
• “Single coronary artery” is a misnomer: because all of the normal coronary
arteries are present
• this entity is not defined by the presence of a single coronary “artery” but
by the fact that all these arteries originate from a single ostium.
• This term is clinical jargon used to refer to cases of CAA that feature a
single coronary ostium, which provides flow to the whole coronary tree
without interruption of continuity and without evidence of collateral
vessels.
