Insulin resistance and triglyceride/hdlc index are strongly associated with coronary artery disease
Background:
Insulin-resistance is associated with cardiovascular disease but it is not used as a marker for disease in clinical practice. Aims: To study the association between the homeostatic model assessment (HOMA-IR) and triglyceride/HDLc ratio (TG/HDLc) with the presence of coronary artery disease in patients submitted to cardiac catheterization.
Methods:
In a cross-sectional study, 131 patients (57.0 10 years-old, 51.5% men) underwent clinical, laboratory and angiographic evaluation and were classified as No CAD (absence of coronary artery disease) or CAD (stenosis of more than 30% in at least one major coronary artery).
Results:
Prevalence of coronary artery disease was 56.7%. HOMA-IR and TG/HDLc index were higher in the CAD vs No CAD group, respectively: HOMA-IR: 3.19 (1.70-5.62) vs......

Acute effect of nitroglycerin on cyclosporine-induced hypertension after cardiac transplantation.
CONCLUSION: After application of nitroglycerin, sBP is reduced immediately in HTX with uncontrolled cyclosporine-induced hypertension. Further studies are needed to evaluate the long-term effect of nitrates in these patients.

Fast Track Speeds Care After Heart Attack
The University of Kentucky is working to save heart attack patients lives by shaving off minutes between the ambulance and treatment at the hospital. So far, treatment time has been reduced by about 35 minutes under a new protocol that calls for certain types of heart attack patients to go straight to the cardiac catheterization lab instead of the emergency room. The protocol is based on research that shows that the risk of death drops 7.5 percent for every half hour shaved off the time between the ambulance and treatment at the hospital for patients with certain kinds of heart attacks.
We hope to have an even higher or 100 percent success rate of timely angioplasty by bypassing the emergency department and taking the patient immediately to the catheterization laboratory f......

Lower Risk Using Radial Access For Cardiac Catheterizations
Cardiac catheterizations have been a groundbreaking tool in the field of cardiology. This procedure offers a minimally invasive means for obtaining important information about the heart and its blood vessels, while also providing a less invasive treatment for certain heart conditions. "A cardiac catheterization is a very important test that allows interventional cardiologists to see the heart as it pumps blood. The information gathered during this procedure cannot be collected by any other means," said Interventional Cardiologist Kimberly Skelding, M.D... (Source: Health News from Medical News Today)...

The Surface Electrocardiogram Predicts Risk of Heart Block During Right Heart Catheterization in Patients With Preexisting Left Bundle Branch Block: Implications for the Definition of Complete Left Bundle Branch Block
Conclusions: An initial r wave of [ge]1 mm in lead V1 suggests intact left to right VS activation and identifies LBBB patients at low risk of CHB during right heart catheterization. These preliminary findings indicate that an initial r wave of [ge]1 mm in lead V1, present in approximately 28% of ECGs with classically defined LBBB, may constitute a new exclusion criterion when defining complete LBBB.

Routine use of fondaparinux in acute coronary syndromes: A 2-year multicenter experience
Conclusions: Between 2006 and 2007, the use of fondaparinux in patients with acute coronary syndromes increased considerably, either because it was used instead of enoxaparin or because of a switch from UFH. Adjusted mortality in patients treated with fondaparinux was lower than with UFH and similar to enoxaparin. (Source: American Heart Journal)...

128-Detector-Row Computed Tomography Coronary Angiography Evaluating Coronary Artery Disease: Who Avoids Cardiac Catheterization?
Conclusion: Among patients referred for computed tomography angiography (CTA) for appropriate indications, 69.6% had either normal coronary arteries or nonobstructive disease. Given the high negative predictive value of coronary CTA, these patients most likely would not require invasive coronary angiography. Selective cardiac CTA may substantially decrease unnecessary diagnostic cardiac catheterizations. (Source: Angiology)...

Vascular access challenge on a patient with cerebral palsy and severe kyphoscoliosis.
We report a case of vascular assess challenge on a patient with severe kyphoscoliosis and joint contractures. Multiple internal jugular (IJ) central venous catheters (CVC) and a peripherally inserted central catheter (PICC) catheterization were attempted via ultrasound guidance and all resulted in malposition. The PICC attempt fortuitously pushed a malpositioned IJ into the correct position. Computed tomography (CT) demonstrated a narrow thoracic inlet with no definite venous stenoses. Therefore, severe chest wall deformity, a narrow thoracic inlet and inadequate positioning of the patient secondary to his contractures all contributed to the malposition of the PICC and CVCs.

Early recovery of left ventricle following coronary artery bypass grafting and mitral valve repair in a case of anomalous origin of left coronary artery from pulmonary artery
We report a critically ill infant with ALCAPA
needing myocardial revascularization and MV repair after which there was early recovery of Left Ventricular (LV) function.
At two years follow up, the child is clinically well; the postoperative cardiac catheterization shows good flow in the Left
Internal Mammary Artery (LIMA) and Left Anterior Descending artery (LAD), good LV function and competent mitral valve.

Cardiac Procedures among American Indians and Alaska Natives compared to Non-Hispanic Whites Hospitalized with Ischemic Heart Disease in California
Conclusion AIAN were not less likely to receive cardiac procedures as non-Hispanic whites during hospitalizations for ischemic heart
disease. Additional research is needed to determine whether differences in specialty referral patterns, patients’ treatment
preferences, or outpatient management may explain some of the health disparities due to cardiovascular disease that is found
among AIAN.

Partial Mechanical Long-Term Support with the CircuLite® Synergy® Pump as Bridge-to-Transplant in Congestive Heart Failure
Thorac cardiovasc Surg 2010; 58: S173-S178DOI: 10.1055/s-0029-1240687Abstract Full mechanical support with a left ventricular assist device (LVAD) is often limited to very sick patients, as the only survival option. This European multicenter study analyzes the effect of partial mechanical support as bridge-to-transplant in a less sick heart failure patient group. The CircuLite® Synergy® device is implanted via a small right-sided thoracotomy with an inflow cannula in the left atrium and an outflow graft connected to the right subclavian artery without the use of extracorporeal circulation. The pump itself sits in a “pacemaker” pocket subcutaneously in the right clavicular groove. It is able to pump up to 3.0 l/min and partially unload the left ventricle. The device was ......

Colonization of central venous catheters in intensive care patients: A 1-year survey in a Portuguese university hospital
To the Editor: Patients admitted at intensive care units (ICUs) often require central venous catheterization. Catheter colonization may lead to bacteremia and, eventually, end up as a catheter-related bloodstream infection. To review the etiology and antimicrobial susceptibility pattern of central venous catheter (CVC) isolates from ICU patients, a retrospective study of the clinical database of Hospital of S. João, in Porto, was performed during a 12-month period. All positive results from the culture of distal tips of CVCs removed from ICU patients and antimicrobial susceptibility pattern of isolates were reviewed.

Case 1—2010 Pulmonary Thrombectomy in an Adult With Fontan Circulation
THE ADULT POPULATION WITH congenital heart disease (CHD) is increasing due to advances in surgical and medical management, with an estimated 850,000 adults with CHD and more than 20,000 patients with CHD transitioning into adulthood annually. This heterogeneous group includes patients with various modifications of the Fontan procedure; a distinct population of particular complexity who require specialized attention and periodic follow-up with their medical care into adulthood. As the adult population who had the Fontan procedure continues to expand, causes of long-term morbidity, including arrhythmias, cyanosis due to systemic venous collateralization, ventricular failure, protein-losing enteropathy, and thrombotic complications, are recognized with increasing frequency. The authors report......
