OBJECTIVES: The aim of this study was to assess the impact of operator experience on prognosis after left main coronary artery (LM) percutaneous coronary intervention (PCI). BACKGROUND: LM PCI can be technically challenging and potentially risky considering the amount of supplied myocardium. METHODS: Consecutive patients who underwent unprotected LM PCI at a single institution were included and compared according to whether the primary operator was an experienced, high-volume LM operator (defined as an operator who performed at least 15 LM PCIs per year for at least 3 consecutive years) or not...

BACKGROUND: Kawasaki disease (KD) is the most common cause of acquired myocardial infarction in children. Coronary artery involvement is the most serious feature of this vasculitis syndrome. Timely diagnosis of coronary artery involvement is of utmost importance since it can prevent long-term morbidity and mortality. The current methods for the diagnosis of coronary artery dilation in KD are inconsistent and are also not capable of detecting all the abnormal coronary arteries or the so-called occult dilations present...

BACKGROUND: In patients undergoing cardiac surgery, a reduced preoperative left ventricular ejection fraction (LVEF) is common and is associated with a worse outcome. Available outcome data for these patients address specific surgical procedures, mainly coronary artery bypass graft (CABG). Aim of our study was to investigate perioperative outcome of surgery on patients with low pre-operative LVEF undergoing a broad range of cardiac surgical procedures. METHODS: Data from patients with pre-operative LVEF ≤40 % undergoing cardiac surgery at a university hospital were reviewed and analyzed...

Background/Aims: This study appraised the long term clinical outcomes of patients treated with percutaneous coronary intervention (PCI) for unprotected left main coronary artery (ULMCA) disease. There are limited data regarding long-term clinical outcomes after PCI for ULMCA disease. Methods: From 2001 to 2011, a total of 448 patients who underwent PCI for ULMCA disease and had 2-year clinical follow-up, were analyzed. The study patients were divided into two groups: group I (stable angina pectoris [SAP], n = 60, 48 men, 62 ± 10 years) and group II (acute coronary syndrome [ACS], n = 388, 291 men, 64 ± 10 years)...

Accumulating evidence from mainly uncontrolled and unblinded clinical studies with various types of ablation catheters have shown that renal denervation (RDN) can be applied safely and is effective in lowering blood pressure (BP) in most patients with treatment resistant hypertension. Sustained BP lowering has been documented up to 3 years at this stage. Furthermore, RDN has been associated with regression of target organ damage, such as left ventricular hypertrophy, arterial stiffness and others. Several studies indicate potential benefit in other common clinical conditions associated with increased sympathetic tone including chronic kidney disease and heart failure...

OBJECTIVE: Inter-arm systolic blood pressure (IASBP) differences ≥10 mmHg are associated with increased cardiovascular risk. Prevalence of IASBP differences is unclear given that studies are mainly in diseased populations and vary in measurement technique (sequential vs simultaneous recording). Moreover, no studies have determined whether dominant or non-dominant arm influences calculated central aortic blood pressure. The purpose of this study was to examine the prevalence of IASBP differences measured at the brachial artery and calculated at the aorta in community dwelling adults...

OBJECTIVE: Rheumatic Heart Disease (RHD), a chronic acquired heart disorder results from Acute Rheumatic Fever. RHD is mostly prevalent in developing nations which is mainly diagnosed by transthoracic echocardiography. Till date, there is no biochemical marker for disease management. In the present study we aim to investigate whether mitral valve remodeling contributes to altered levels of circulating biomarkers of collagen metabolism in rheumatic heart disease. DESIGN AND METHOD: The study involved RHD subjects with before and after valve replacement surgery which includes age and sex matched controls...

We report a 38-year-old woman with a left lung tumor presenting as obstructive pneumonia. Bronchoscopic examination revealed a polypoid tumor filling the left main bronchus. The tumor was partially resected by a snaring procedure for diagnostic purposes. Microscopic examination revealed a submucosal tumor located underneath normal bronchial epithelium. The tumor was composed of sheets of uniform oval to cuboidal cells encompassing numerous blood vessels. Immunohistochemically, the tumor cells exhibited smooth muscle markers, but were negative for neuroendocrine markers...

Prediction of left main coronary artery (LMCA) or equivalent disease is important with regard to selecting the appropriate treatment strategy. The classical electrocardiographic pattern of LMCA disease includes ST elevation (STE) in lead aVR in the presence of extensive ST depression (most prominent in leads I, II, and V4-6) with the STE in aVR≥V1. Patients with these findings may potentially require early coronary angiography and coronary bypass surgery; therefore selected patients with these findings on exercise testing might benefit from more urgent or expedited angiography...

The clinical utility of the Mini-Mental State Examination (MMSE) and its shorter version (SMMSE) is still debated. There is a need to better understand the neuroanatomical correlates of these cognitive tests. The objective of this cross-sectional study was to determine whether lower MMSE and SMMSE scores correlated with focal brain volume reduction in older adults. Participants from the GAIT study (n = 207; mean, 70.9±5.9 years; 57% female; mean MMSE 26.2±3.9; mean SMMSE 5.1±1.1) were evaluated using the MMSE and SMMSE and received a 1...

Dilated cardiomyopathy is a rare cardiac disease characterized by left ventricular dilatation and systolic dysfunction leading to heart failure and sudden cardiac death. Currently, despite several conditions have been reported as aetiologies of the disease, a large number of cases remain classified as idiopathic. Recent studies determine that nearly 60% of cases are inherited, therefore due to a genetic cause. Progressive technological advances in genetic analysis have identified over 60 genes associated with this entity, being TTN the main gene, so far...

INTRODUCTION AND OBJECTIVES: Primary hyperparathyroidism (PHPT) can be found in concomitance with thyroid disease (TD) in a high frequency of cases. In this context the diagnostic exams for localizing the enlarged parathyroid(s) gland(s) could be less reliable or nonconclusive. Moreover, the thyroid carcinoma seems to be more frequent compared to that isolated thyroid desease and, therefore, carefully investigated. The main goal of the present study is to evaluate which diagnostic tool (US, MIBI) is more reliable for localizing the site of the PTH hypersecretion and to confirm if it is always advantageous a combination of both exams...

BACKGROUND: Laparoscopic surgery for colon cancer is associated with improved recovery and similar cancer outcomes at 3 and 5 years in comparison with open surgery. However, long-term survival rates have rarely been reported. Here, we present survival and recurrence rates of the Dutch patients included in the COlon cancer Laparoscopic or Open Resection (COLOR) trial at 10-year follow-up. METHODS: Between March 1997 and March 2003, patients with non-metastatic colon cancer were recruited by 29 hospitals in eight countries and randomised to either laparoscopic or open surgery...
