Iatrogenic aortocardiac fistulae have been described rarely following intracardiac repair. This 28 year-old-male presented to our facility with dyspnea going on 20 days after closure of ventricular septal defect (VSD) and resection of subaortic membrane. A communication was noticed between the aorta and the right ventricle (RV) upon transthoracic echocardiography. Cardiac catheterisation revealed a significant shunt and an aortogram revealed a 6 mm communication between aorta and right ventricle. Percutaneous closure of this defect was attempted under local anaesthesia through right femoral access...

An operator can be unaware that the guide wire has accidentally advanced into space outside the previous stent, which can result in deformation of the previous stent when a new stent is deployed outside the prior stent. We herein have reported a case of accidental guide wire advancement into a previously dissected lumen of right coronary artery (RCA), resulting in a new stent deploying outside the prior stent, resulting in deformity of the prior stent. Thrombus and friable atheromatous plaques dislodged and migrated to occlude distal RCA when attempting to restore the proximal luminal diameter by balloon inflation, resulting in profound shock with asystole...

Intravascular ultrasound (IVUS) can provide valuable information during the intervention of difficult chronic total occlusion (CTO) lesion. Stumpless CTO lesions with an adjacent side branch are associated with a significantly lower success rate because the proper entry point is not always clearly identified and the guidewires easily slip into the side branch. Herein we presented a case of a stumpless middle left circumflex (LCX) artery CTO lesion with auto-collateral from obtuse marginal branch. Initially, we positioned the IVUS into the side-branch to find the entry point of LCX-CTO lesion...

We report on a healthy 11-year-old girl who presented to our facility with sudden onset of fainting in a strenuous running course. Transthoracic echocardiography at short-axis view showed a diastolic flow into the main pulmonary artery (PA). The diagnosis of left anterior descending artery (LAD) to PA fistula was documented by cardiac computed tomography and catheterization. Interventional therapy of LAD to the main PA fistula was not performed because of no evidence of myocardial ischemia or significant hemodynamic change...

BACKGROUND: Thallium-201 myocardial perfusion image (MPI) is commonly used to detect coronary artery disease in patients with chest pain. Although a normal thallium-201 MPI result is generally considered to be a good prognosis and further coronary angiogram is not recommended, there are still a few patients who suffer from unexpected acute coronary events. The aim of this study was to investigate the clinical prognosis in patients with normal thallium-201 MPI. METHODS: From January 2006 to August 2012, a total 22,003 patients undergoing thallium-201 MPI in one tertiary center were screened...

BACKGROUND: Acute pulmonary embolism is a serious medical condition that has a substantial global impact. Inflammation plays a role in the pathophysiology and prognosis of acute pulmonary embolism (APE). The aim of the present study was to investigate the prognostic value of admission parameters for complete blood count (CBC) in APE. METHODS: A total of 203 patients who were hospitalized with diagnosed APE were retrospectively enrolled in the study. Clinical data, PESI scores, admission CBC parameters, neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) were all recorded...

BACKGROUND: Increased microvascular resistance due to chronic inflammation is assumed to be one of the mechanisms associated with coronary slow flow (CSF). Previous studies have shown that the platelet-to-lymphocyte ratio (PLR) and the neutrophil-lymphocyte ratio (NLR) are markers of inflammation for various diseases. In this study we aimed to evaluate the relationship between CSF and PLR-NLR. METHODS: Seventy-eight patients with CSF and 50 patients with normal coronary flow were enrolled into this study...

BACKGROUND: In-stent restenosis following the insertion of conventional drug-eluting stent has become an extremely serious problem due to coating techniques, with polymer matrices used to bind biological ingredients to the stent surface. However, several studies have indicated that new pro-healing technique could prevent stent thrombosis that can be caused by conventional drug-eluting stents. METHODS: A novel method of attaching anti-CD34 antibodies directly on the porous surface of a 316L stainless steel bare metal stent was developed in this study, which achieved both high stability of attached anti-CD34 antibodies on the metal stent surface and high antibody activity for stem cell capture...

BACKGROUND: When acute aortic dissection is complicated with acute myocardial infarction, the diagnosis of dissection can be problematic. In these cases, patients might be treated with primary percutaneous coronary intervention (PCI) and suffer acatastrophic outcome. However, there are few reports or algorithm to facilitate the accurate management of this clinical situation. METHODS: We evaluated 385 consecutive patients who underwent primary PCI arising from an initial diagnosis of STEMI at our hospitalbetween January 2006 and March 2011...

Atrial fibrillation (AF) is the most common cardiac arrhythmia. Chronic kidney disease (CKD) is associated with a high prevalence of AF, and uremic toxins are an important risk factor for cardiovascular diseases associated with CKD. Uremic toxins can produce pro-fibrotic, pro-hypertrophic, and pro-inflammatory effects on cardiac tissues and enhance oxidative stress or neurohormonal phenomena of cardiovascular injury, which are recognized as arrhythmogenic factors of AF. This article reviews the clinical, molecular, and electrophysiological data of uremic toxins in CKD considered to induce AF through multiple mechanisms on structural and electrical remodeling of the cardiovascular system...

UNLABELLED: Pulmonary embolism (PE) is a complication of underlying vascular thrombosis. The causes of PE are multi-factorial, and patients with PE present with various symptoms. We herein have presented the case of a 21-year-old man who initially developed palpitation, dyspnea, and seizure. Computed tomography of the chest ultimately indicated PE, and antiphospholipid syndrome (APS) was diagnosed with clinical thrombosis events and series presence of antiphospholipid antibodies. APS commonly causes vascular thrombosis within the vascular tree; however, nonthrombotic manifestations, such as seizure, may also occur...
