The current study investigates the effect of multi stenosis on the hemodynamic parameters such as wall pressure, velocity and wall shear stress in the realistic left coronary artery. Patients CT scan image data of normal and diseased left coronary artery was chosen for the reconstruction of 3D coronary artery models. The diseased 3D model of left coronary artery shows a narrowing of more than 70% and 80% of area stenosis (AS) at the left main stem (LMS) and left circumflex (LCX) respectively. The results show that the decrease in pressure was found downstream to the stenosis as compared to the coronary artery without stenosis...

The quadrangular space is a space in the axilla bounded by the inferior margin of the teres minor muscle, the superior margin of the teres major muscle, the lateral margin of the long head of the triceps brachii muscle and the surgical neck of the humerus, medially. The axillary nerve (C5-C6) and the posterior circumflex humeral artery and veins pass through this space in order to supply their territories. The subscapularis muscle is situated into the scapular fossa and inserts itself into the lesser tubercle of the humerus, thus helping stabilize the shoulder joint...

Anomalies of the coronary arteries are reported in 1-2% of patients among diagnostic angiogram. Dual origin of a circumflex from both sinuses is extremely rare among them. We report a case of a patient who underwent primary percutaneous coronary intervention for acute inferior wall myocardial infarction where left coronary injection demonstrated normal obtuse marginal and right coronary injection demonstrated normal right coronary artery (RCA). On further probing, an anomalous left circumflex (LCx) artery was seen arising from RCA ostium which was subsequently cannulated and revascularized by deployment of 2...

BACKGROUND: The etiology of Kawasaki disease (KD) remains unknown. However, many studies have suggested that specific genetic factors and/or some infectious agents underlie the onset of KD. Previous studies have suggested that human adenovirus (HAdV) is one of the triggering pathogens of KD. Here, we report monozygotic twin boys who sequentially developed KD in conjunction with acute HAdV type 3 (HAdV-3) infection. CASE PRESENTATION: The patients were four-year-old monozygotic twin boys...

Reconstruction of dorsalis pedis with soft tissue is challenging because it needs to preserve thin structure to ensure that the patient will be able to wear shoes. Here, we report the use of a thin superficial circumflex iliac artery perforator (SCIP) flap in dorsalis pedis reconstruction. A 67-year-old man presented with a third-degree burn, which exposed his extensor tendons. A thin SCIP flap from the left inguinal region measuring 15 × 4 cm was transferred to the dorsalis pedis region. Postoperatively, no major cosmetic or functional problems were observed...

Iatrogenic injury to the circumflex artery (Cx) due to its close proximity to the mitral annulus is a rare but dreadful complication that can occur during mitral valve repair. The aim of our study was to compare multiple measurements of the Cx datasets, obtained by real time three-dimensional transesophageal echocardiography (RT3D TEE) and corresponding measurements assessed in multi-planar three-dimensional images acquired by multidetector computed tomography (MDCT). Preoperative RT3D TEE and MDCT datasets of 25 patients who had previously undergone minimally invasive mitral valve surgery were retrospectively analyzed...

Large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronary artery occlusion. In contrast to collateral vessels that are seen in the presence of critical coronary artery stenosis and total occlusions, these arterial communications are vessels that are single, extramural, straight, and large in diameter...

Cardiac manifestations of the hydatid cyst are relatively uncommon. Cardiac involvement may lead to the compression of vital organs, pulmonary hypertension, pericardial effusion, and even anaphylaxis. A 45-year-old woman presented to the Emergency Department of Tehran Heart Center with chest pain. Cardiac examination revealed relatively muffled heart sounds. Echocardiography demonstrated a round echolucent well-defined mass (47 × 25 mm) on the base and the mid lateral wall of the left ventricle (LV) without septation...

Coronary artery fistula (CAF) is an abnormality in which the coronary artery has an anomalous connection with a venous structure such as the coronary sinus or atrium. CAF is usually congenital, but may be acquired. The prevalence in the general population is low with many asymptomatic and discovered incidentally. When symptomatic, CAF may present with dyspnea, decreasing functional capacity, and/or arrhythmia. We report a case of a young otherwise healthy active duty male with progressive symptoms of dizziness and exertional fatigue with paroxysmal atrial fibrillation...

We aimed to assess the correlation between angiographic and physiologic evaluation of coronary lesions in aortic stenosis (AS) patients presenting with intermediate coronary stenoses at the angiography. From 2002 to 2010, we included 163 patients from 2 centers with both AS and coronary artery disease (CAD), matched by age and gender with 163 contemporary patients with CAD alone. With both quantitative coronary angiography and fractional flow reserve (FFR), we assessed 259 coronary stenoses in the AS + CAD group, and 256 in the CAD alone group...

INTRODUCTION    Prevalence and impact of total coronary occlusion of an infarct-related artery (IRA) on outcome could be different between patients with Non-ST-Elevation Myocardial Infarction (NSTEMI) and ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). OBJECTIVES    We evaluated the impact of IRA occlusion on outcome of myocardial infarction, according to the presence or absence of ST-segment elevation and the culprit lesion location. PATIENTS AND METHODS    We analyzed 4581 STEMI patients and 2717 NSTEMI patients enrolled in the Polish Registry of Acute Coronary Syndromes who underwent PCI...

We evaluated the correlation of the left main coronary bifurcating angle (LCBA) with the severity of coronary atherosclerosis, risk factors of coronary artery disease (CAD) and the feasibility of measuring the LBCA using the axial plane. Coronary Computed tomography angiographies (CTAs) of 313 patients between Nov. 2006 and Oct. 2013 were reviewed and separated into three groups. Group I (211 patients) had significant stenosis (≥50%) of the left anterior descending coronary artery (LAD) and/or left circumflex coronary artery (LCX)...

OBJECTIVES: This study sought to compare long-term clinical outcome in ST-segment elevation myocardial infarction (STEMI) patients with a concomitant chronic total occlusion (CTO) with well-developed versus poorly developed collaterals toward the CTO. BACKGROUND: In STEMI patients, presence of a CTO is associated with increased morbidity and mortality. CTOs are often (partially) perfused by collateral vessels. Therefore, when the infarct-related artery (IRA) is the main donor vessel for the collateral blood supply of the CTO, infarct size may increase significantly...

Phasic coronary artery compression is typically associated with spasm or myocardial bridging. Compression caused by acquired anatomic changes to the surrounding heart chambers has been reported only infrequently. We present a possibly unique case of phasic compression of the proximal left circumflex coronary artery during atrial contraction in association with a dilated left atrium. A 55-year-old man with multiple cardiac risk factors presented with worsening exertional dyspnea. An electrocardiogram and echocardiogram revealed marked left atrial dilation and a left ventricular ejection fraction of 0...
