Project description:Congenital anomalous origin of coronary arteries is rare and occurs in 0.2%-2% of patients undergoing coronary angiography (CAG). Most of the cases are benign but may present with life-threatening symptoms such as myocardial ischemia or sudden cardiac death. The prognosis depends on the site of origin of the anomalous artery, intramyocardial course, and relation to other great vessel and cardiac structures. Increased awareness and easy availability of noninvasive methods like computed tomography CAG have led to more reporting of such cases. Here, we report the case a 52-year-old male with a double right coronary artery having anomalous origin from a noncoronary aortic cusp detected during CAG which has not been reported in the literature before.
Project description:We report a rare coronary artery anomaly-anomalous origin of the left anterior descending artery from the pulmonary artery in a 40-year-old woman. The uniqueness of this case is the absence of any significant morbidity from this condition in adulthood which is in contrast to other reported cases where patients present with myocardial infarction, congestive heart failure, and sometimes death during the early infantile period.(1).
Project description:Congenital anomalies of coronary arteries are a group of diseases that are infrequently found. Their prevalence has been reported from 0.6% to 1.3%. Most clinical manifestations are benign and asymptomatic. Congenital absence of the left circumflex artery is a very rare congenital anomaly of the coronary circulation, and only a few cases have been reported in the literature. We report a case of a 51-year-old man who underwent a cardiac catheterisation. Coronary angiography showed a left anterior descending coronary artery with no circumflex and a dominant right coronary artery.
Project description:The present case report is computed tomography (CT) coronary angiographic depiction of an exceedingly rare entity-single right coronary artery arising from the right sinus of Valsalva with the absence of equivalent left coronary artery system branches and associated mitral valve prolapse. Even though a statistical rarity, it is potentially fatal and can cause myocardial ischemia, sudden cardiac death, and warrants immediate clinical attention. Further, the report reveals the decisive role of CT coronary angiogram in the diagnosis of such rare entities, in contrast to catheter angiography, which may be inconclusive.
Project description:Atrial myxomas are the most common primary heart tumors. Two-dimensional echocardiography is the diagnostic procedure of choice. The majority of myxomas are located in the left atrium. Myxoma in the right atrium is an uncommon location. The co-occurrence of right atrial myxoma with atherosclerotic coronary artery disease (CAD) is uncommon. In our case, right atrial myxoma was associated with CAD, which makes it a unique case because very few cases of right atrial myxoma coexistent with CAD are described in literature.
Project description:Congenital absence of left circumflex artery is a rare occurrence and very few cases have been reported in literature. It is a benign incidental finding; however some patients present with sudden onset chest pain mimicking acute coronary syndrome often resulting in detection of this rare anatomy on coronary angiography. Coronary computed tomography angiography is a relatively new noninvasive imaging modality which can be used to confirm this suspicion and diagnose this unique morphology reliably.
Project description:An 8-month-old female experienced a life-threatening right coronary artery rupture resulting from cardiopulmonary resuscitation (CPR) 1 week after corrective surgery for Tetralogy of Fallot (TOF). Emergency exploratory thoracotomy was performed due to uncorrectable hemorrhagic shock. During exploration, active bleeding was detected in the anterior branch of the right ventricular coronary artery. After the repair, the patient's condition improved. Coronary artery rupture is an extremely rare complication of CPR. Here, we present a case that provides new reflections and warnings to clinicians.
Project description:BackgroundSingle coronary artery (SCA) is a rare congenital coronary anomaly with incidence of 8-66 per 100 000 cases. Percutaneous coronary intervention (PCI) in patients with SCA is technically challenging. This is a case of bifurcation angioplasty involving left anterior descending/right coronary artery (LAD/RCA) in a patient with SCA and 1-year follow-up with computed tomography coronary angiography (CTCA).Case summaryA 52-year-old female with history of PCI to LAD 4 months back, presented with non-ST-elevation myocardial infarction. Coronary angiogram showed 90% stenosis in mid-LAD, distal to the previous stent and proximal to an anomalously originating RCA from mid-LAD. She was planned for LAD/RCA provisional bifurcation angioplasty and a drug-eluting stent was deployed in LAD across RCA, following which patient developed angina with ischaemic electrocardiogram (ECG) changes due to significant pinching of RCA. Using Reverse crush technique, RCA was stented successfully with resolution of angina and ECG changes. At 1-year follow-up, patient is in New York Heart Association class I with normal left ventricular function and patent LAD/RCA bifurcation stent on CTCA.DiscussionSCA poses a great challenge to interventional cardiologists during PCI, especially in the event of a complication. Detailed anatomical knowledge, appropriate hardware and operator expertise are the key factors for successful PCI of SCA. This is, to the best of our knowledge, the first case report of bifurcation angioplasty of LAD/RCA in a rare case of SCA. This case also describes the use of reverse crush technique as a bailout strategy during provisional bifurcation angioplasty.
