We report a case of anomalous origin of the left circumflex coronary artery arising from the right pulmonary artery resulting in stress-induced cardiac arrest. The patient collapsed after running a 5K race and was resuscitated. Subsequent workup revealed the culprit anatomy, which was successfully treated with surgical ligation. To the authors' knowledge, this is only the second case of this va...

BACKGROUND Because of the rarity of this condition, information on pregnancy-associated spontaneous coronary artery dissection is limited. We reviewed a large number of contemporary pregnancy-associated spontaneous coronary artery dissection cases in an attempt to define the clinical characteristics and provide management recommendations. METHODS AND RESULTS A literature search for cases of p...

the anomalous origin of the right coronary artery (rca) as a branch from the left anterior descending artery (lad) is a very rare variation of the single coronary artery anomaly. the anomalous vessel arises from the proximal or midportion of the lad and courses anterior to the pulmonary artery trunk in most instances. in this case report, a 61-year-old woman is introduced who underwent coronary...

Knowledge of morphometric quantities of coronary arteries in infants is an increasingly vital component in managing congenital and acquired heart disease. Because of considerable heterogeneity of coronary vasculature, what is considered atypical and aberrant or insignificant anatomy is often unclear. The purpose of our present study is to define normal infant anatomy. This was done by focu...

Aims: We present this case to raise awareness of this unusual presentation of a malignant anomalous right coronary artery arising from the left coronary cusp in a patient older than 50 years. We describe a useful imaging modality and discuss therapy. Presentation of the Case: We report a case of a 63-year-old male with an interarterial coursing right coronary artery arising from the left corona...

Anomalous origin of the right coronary artery from the main pulmonary artery is a rare congenital cardiac malformation. Most patients remain asymptomatic. However, there are cases of sudden cardiac death described in the literature, indicating a potentially malign course of the disease. To establish a double-ostium coronary system, correction of the aberrant vessel is recommended. Despite surgi...

Invasive coronary angiography and computed tomography (CT) coronary angiography directly visualise coronary anatomy but do not provide information about the presence of inducible myocardial ischaemia. Due to its excellent negative predictive value CT coronary angiography is a suitable test to exclude significant coronary artery disease. However, given its high rate of false positive results par...

THE DOG is used a great deal in physiological and surgical research on the heart. In view of this, it is surprising that information with regard to the anatomy of the coronary S3stem is somewhat incomplete and inconsistent. This may account for the variations reported in mortality rate from acute ligations. A right descending coronary artery is described by Bradley which is not confirmed by oth...

atients with unprotected left main coronary artery disease (LMCA) have a worse prognosis than any other form of coronary artery disease (CAD). During the past decade, the efficacy and safety of percutaneous coronary intervention (PCI) vs. coronary artery bypass grafting (CABG) for LMCA have been major topics for both interventional cardiologists and cardiac surgeons. CABG has been considered as...

OBJECTIVE To determine coronary artery anomalies in tetralogy of Fallot in Pakistani children as seen on angiography. STUDY DESIGN Case series. PLACE AND DURATION OF STUDY The National Institute of Cardiovascular Diseases, Karachi, Pakistan from July 2006 to July 2007. METHODOLOGY Children under 15 years of age with echocardiographic diagnosis of tetralogy of Fallot were included in the s...
