Despite being one of the most common causes of supraventricular tachycardia in young adult, there are not many studies that highlight the demographics data as well as procedural characteristics of accessory pathway in Saudi Arabia.

Unprotected Left Main Coronary Artery (ULMCA) disease is defined as significant stenosis in the Left Main Coronary Artery (LMCA) and there were no previous Coronary artery bypass surgery (CABG) or patent bypass grafts to the left anterior descending (LAD) or left circumflex (LCX) arteries

Scimitar syndrome is a rare congenital anomaly seen as one of the components of congenital pulmonary venolobar syndrome. Simple and traditional investigation tools like CXR if interpreted with vigil can aid in prompt diagnosis and management of patients even in absence of clinical symptoms.

We report a patient in the sixth decade of life with a benign anomalous course and a history of atherosclerotic disease in the right coronary artery with the presence of ischemia. We present a clinical case of infrequent finding of abnormal left coronary artery and obstructive atherosclerotic lesion in the circumflex artery. The authors decided to perform coronary angioplasty on the lesion found. Because it is an infrequent condition, we conducted a literature search in which we focused on the statistical findings, the clinical presentation and detailed the treatment of the patient by means of coronary angioplasty. Despite the difficulty of the case, success was achieved.

Background: This study was designed to evaluate the patterns of coronary artery disease in patients with chronic obstructive pulmonary disease (COPD) presenting with the acute coronary syndrome (ACS). Methods: This was a prospective, observational study, conducted on 69 patients with chronic obstructive pulmonary disease, presenting with acute coronary syndrome undergoing coronary angiogram from September 2017 to March 2021. All patients had undergone coronary angiogram; severity and morphology of lesion as well as the severity of calcium were analyzed. Results: The study showed that 69 patients with COPD who presented with ACS, 58.8% of patients were presented with NSTEMI, 30.2% STEMI and Unstable angina 11%. The average time of presentation after the onset of the symptom was 17.6 hours. 64% of patients were a smoker. Coronary involvement 10% of patients had LM, 50% TVD, 30% DVD, and 10% had SVD. Type a coronary lesion was seen in 5%, Type B in 20%, and Type C in 75% of patients. Mild Coronary calcium was seen in 25%. Moderate calcium was in 40% and severe calcium in 35%. Conclusions: COPD patients presenting with ACS, associated with increased severity of coronary calcium and coronary lesions.
