Coronary angiography is the golden choice for coronary artery disease evaluation and management. However, as with any invasive procedures, there is a risk of complications. We are reporting a case of 69-year-old male with past medical history of cardiac bypass surgery, CHF, hypertension, and hyperlipidemia who was admitted to the hospital to evaluate his chest pain. He had treadmill stress test that showed ischemic induced exercise. Patient underwent coronary angiography that showed proximal complete occlusion of the RCA with a patent graft. At the end of the procedure, the patient did not wake up and remained minimally responsive. An urgent brain MRI was ordered and showed infarctions consistent with an artery of Percheron infarction. Later, patient has improved slowly and was discharged home. We briefly here discuss this rare complication including the risk factor, clinical presentation, and the management.

Background: Flecainide is a useful antiarrhythmic for atrial fibrillation (AF). However, because of ventricular proarrhythmia risk, a history of myocardial infarction (MI) or coronary artery disease (CAD) is a flecainide exclusion, and stress testing is used to exclude ischemia. We assessed whether absent/mild coronary artery calcium (CAC) can supplement or avoid the need for stress testing. Methods: We assessed ischemic burden using regadenoson Rb-82 PET/CT in 1372 AF patients ≥50 years old without symptoms or signs of clinical CAD. CAC was determined qualitatively by low dose attenuation computed tomography (CT) (n = 816) or by quantitative CT (n = 556). Ischemic burden and clinical outcomes were compared by CAC burden. Results: Patients with CAC absent or mild (n = 766, 57.2%) were younger, more frequently female, and had higher BMI but lower rates of diabetes, hypertension, and dyslipidemia. Average ischemic burden was lower in CAC-absent/mild patients, and CAC-absent/mild patients showed greater coronary flow reserve, had fewer referrals for coronary angiography, and less often had obstructive CAD. Revascularization at 90 days was lower, and the rate of longer-term major adverse cardiovascular events was favorable. Conclusions: An easily administered, inexpensive, low radiation CAC scan can identify a subset of flecainide candidates with a low ischemic burden on PET stress testing that rarely needs coronary angiography/intervention and has favorable outcomes. Absent or mild CAC-burden combined with other clinical information may avoid or complement routine stress testing. However, additional, ideally randomized and multicenter trials are indicated to confirm these findings before replacing stress testing with CAC screening in selecting patients for flecainide therapy in clinical practice.

Background Treadmill stress test (TMT) is the most commonly performed stress test for diagnosis of coronary artery disease (CAD) in outpatient setting. The present study was conducted to find correlation of TMT with coronary angiography (CAG) in males versus female patients. Methods Total 422 patients who had undergone CAG and TMT were enrolled in present study. TMT test was done using Bruce protocol, and results were classified as inconclusive, low, intermediate, and high probability for inducible ischemia. Results Of 422 patients enrolled in the present study, 290 (69%) were males and 132 (31%) were females. Clinical presentation was angina on exertion CCS class II–III in 302 (71.6%) patients and angina equivalent in 124 (29.4%) patients. Out of these, 211 (50.2%) were diabetic and 308 (72.9%) were hypertensive. TMT was inconclusive, low, intermediate, and high probability for inducible ischemia in 35 (8.2%), 40 (9.7%), 19 (4.5%), and 328 (77.7%) patients, respectively. CAGs were normal in 149 (35.4%) patients and abnormal in 273 (64.6%) patients. Out of 328 patients with strongly positive TMT, 104 (31.7%) had normal coronaries, 56 (17%) had mild CAD, while 75 (22.8%) had SVD. LMCA disease, DVD, and TVD were found in 5 (1.5%), 48 (14.6%), and 40 (12.1%) patients, respectively. Of 132 female patients, 70 (53%) were found to have CAD and 62 (47%) had normal coronaries on CAG. Of 290 males, 241(83.1%) were found to have CAD and 49 (16.8%) had normal coronaries on CAG. Positive predictive value (PPV) in females was 53% and in males was 83%. Subgroup analysis showed that if there was high-probability TMT along with older age (p < 0.00), male sex (p < 0.01), and diabetes (p < 0.00), chances of having CAD were more. Conclusion PPV of positive TMT in female is 53% and in male is 83%. High-probability TMT along with the older age, male sex, and presence of diabetes mellitus (DM) makes the probability of having CAD is high.

A 48-year-old man presented to the emergency department (ED) with exertional chest pressure associated with palpitations and lightheadedness. He was found to have non-sustained ventricular tachycardia (NSVT) in the ED, which resolved spontaneously. Given his history of hyperlipidaemia, unknown family history due to being adopted and episode of NSVT in the ED, he underwent cardiac catheterisation, which showed non-obstructive coronary artery disease and distal left anterior descending artery myocardial bridge (MB). The patient subsequently underwent ECG treadmill stress test with reproduction of chest pressure and NSVT. The patient was referred to cardiac surgery for definitive management of symptomatic MB and underwent resection of MB.

Background:Use of MRI with diffusion-weighted imaging (DWI) can identify infarcts in 30%–50% of patients with TIA. Previous guidelines have indicated that MRI-DWI is the preferred imaging modality for patients with TIA. We assessed the frequency of MRI utilization and predictors of MRI performance.Methods:A review of TIA and minor stroke patients evaluated at Veterans Affairs hospitals was conducted with regard to medical history, use of diagnostic imaging within 2 days of presentation, and in-hospital care variables. Chart abstraction was performed in a subset of hospitals to assess clinical variables not available in the administrative data.Results:A total of 7,889 patients with TIA/minor stroke were included. Overall, 6,694 patients (84.9%) had CT or MRI, with 3,396/6,694 (50.7%) having MRI. Variables that were associated with increased odds of CT performance were age >80 years, prior stroke, history of atrial fibrillation, heart failure, coronary artery disease, anxiety, and low hospital complexity, while blood pressure >140/90 mm Hg and high hospital complexity were associated with increased likelihood of MRI. Diplopia (87% had MRI, p = 0.03), neurologic consultation on the day of presentation (73% had MRI, p < 0.0001), and symptom duration of >6 hours (74% had MRI, p = 0.0009) were associated with MRI performance.Conclusions:Within a national health system, about 40% of patients with TIA/minor stroke had MRI performed within 2 days. Performance of MRI appeared to be influenced by several patient and facility-level variables, suggesting that there has been partial acceptance of the previous guideline that endorsed MRI for patients with TIA.

Background and Aims: The use of coronary angiography in diagnosing coronary artery disease is limited by its invasive property. In the other hand correct interpretation of tread mill test data and its use as a key diagnostic modality also has been a problem. The study was thus aimed to see the diagnostic accuracy of treadmill test to rule out coronary artery disease.Methods: We included all the patients who had positive tread mill stress test and underwent coronary angiography and were subsequently analyzed for presence of coronary artery disease.Results: A total of 303 patients were included with 119 males and 184 females with mean age of 53.6±10.5 yrs and 51.7±8.6 yrs respectively. Normal coronaries was seen in 114(54.0%), borderline lesion in 29 (13.7%) and significant lesion in 68 (32.2%) with 48(22.7%) having single vessel disease, 29(13.7%) double vessel disease and 14(6.6%) triple vessel disease. Coronary artery diseases was highest among diabetics (57.7%, OR 1.72 (95 % CI: 0.92 to 3.20), p value-0.08).Similarly the risk of coronary artery disease was significantly highest among patient with ≥2 risk factor (OR: 8.10,95 % CI: 4.96 to 13.24, P < 0.0001). Gender distribution showed that coronary artery disease was significantly higher in males than females (53% vs 35% respectively, OR: 2.08, 95 % CI: 1.30 to 3.32, p value-0.002).Conclusion: The value of tread mill test to predict coronary artery disease is highest in patients with two or more risk factor especially in those with diabetes with significance increased among males.

Immunoglobulin G4-related disease characteristically involves multiple organs including the heart and coronary arteries. Immunoglobulin G4-related coronary artery disease is thought to be due to periarteritis and histopathologically is characterized by marked thickening of the adventitia and periarterial fat with infiltration of immunoglobulin G4-positive plasma cells. Although comprehensive diagnostic criteria require a biopsy for a definite or probable diagnosis of immunoglobulin G4-related disease, obtaining a coronary artery biopsy is difficult and risky. However, imaging findings including coronary angiography and intravascular ultrasound might be useful tools to establish a diagnosis of immunoglobulin G4-related coronary artery disease. We report a case of a 63-year-old man with a history of immunoglobulin G4-related disease who presented with exertional chest pain. We found unique angiographic and intravascular ultrasound features of immunoglobulin G4-related coronary artery disease that distinguished it from those of arteriosclerotic coronary artery disease and suggest that coronary angiography and intravascular ultrasound might be useful tools in the diagnosis of immunoglobulin G4-related coronary artery disease.

Abstract Introduction: We present the case of a young man with multiple atherosclerotic risk factors and a rare cause of angina and supraventricular ectopic beats. Case presentation: A 35-year-old man with one-year history of stable angina pectoris and supraventricular ectopic beats, without any medication, presented to the emergency room complaining of anterior chest pain that occurs at moderate physical exertion. The rest electrocardiogram, transthoracic echocardiography, and chest X-ray were normal; the exertion stress test was also normal, except for supraventricular ectopic beats (trigeminal rhythm). Due to the intermediate pre-test probability of coronary artery disease, he was evaluated using coronary computed tomography angiography. An anomalous origin of the right coronary artery from the left coronary sinus, with an inter-arterial course and without any atheroma plaques, was observed. During hospitalization the evolution was stable, without complications. The patient was further referred to a cardiac surgery clinic to evaluate the possibility of surgical treatment of this anomaly. Conclusions: Coronary artery anomalies are very rare; however, they present multiple implications in current practice. The most severe complication of this condition is represented by sudden death in young patients due to malignant ventricular arrhythmias. Imaging diagnostic techniques allow for a rapid, noninvasive diagnosis of this rare cause of angina.
