Percutaneous coronary intervention (PCI) in an anomalous right coronary artery (RCA) can be technically difficult because selective cannulation of the vessel may not be easy. We thereby present two cases with unstable angina pectoris of anomalous originated RCA. The PCI were successfully performed in two patients with a special guiding wire manipulating skill which we called "gone with the flow...

For a number of years root cause analysis (RCA) has been used when an adverse event has occurred. It is generally accepted that adverse events do have causes, and that a careful analysis of the actions of persons and the states of the system in which the event occurred will reveal the causal agents. It remains only to select the most reasonable cause from the myriad of competing causes to bring...

Myocardial infarction (MI) secondary to coronary artery fistula and the subsequent occlusion of the distal right coronary artery (RCA) after blunt chest trauma is a rare entity. Here, we describe a case of coronary artery fistula and occlusion with an inferior MI that occurred following blunt chest trauma. At the initial visit to the emergency room after a car accident, this patient had been un...

The case study presented in this article focuses on the common pitfall in which many defect prevention activities fall, caused by inconsistency of data. Before any collected Root Cause Defect Analysis (RCA) data can be used reliably, an analysis of the variation due to the measurement system itself such as a Gauge R&R study, should be performed. This allows to understand of the integrity of the...

OBJECTIVE This study aimed to assess the incidence of coronary anomalies using 64-multi-slice coronary computed tomography (MSCT). METHODS The diagnostic MSCT scans of 745 consecutive patients were reviewed. RESULTS The incidence of coronary anomalies was 4.96%. The detected coronary anomalies included the conus artery originating separately from the right coronary sinus (RCS) (n = 8, 1.07%...

42-year-old diabetic woman presented with left ventricular dysfunction late after an Aanterior wall myocardial infarction. Fluoro-deoxy glucose-positron emission tomography showed viability in the left anterior descending artery (LAD) territory. Coronary angiogram (A, Online Video 1) showed a significant mid-LAD disease which was stented. Fractional flow reserve (B) done for the borderline lesi...

The prognosis of patients in whom the right coronary artery (RCA) arises from the left coronary sinus (LCS) is unequal. An initial intramural course of the coronary artery within the aortic media is considered to cause myocardial ischemia in cases of coronary anomalies. In this case report, we present one patient admitted due to chest pain on exertion that suggested angina. Her only risk factor...

BACKGROUND Intrahepatic hepatitis B virus (HBV) covalently closed circular DNA (cccDNA) is the original template for HBV replication. The persistence of cccDNA is responsible for the recurrence of HBV infection. The detection of cccDNA can help the development of new antiviral drugs against HBV replication links, and reduce the resistance and recurrence as well as to discover extrahepatic HBV i...
