The very nice study by Narins et al described in this edition of the Journal of Invasive Cardiology compares 75 patients randomized to vascular closure using a topical patch containing a polysaccharide-based procoagulant with 75 patients randomized to manual compression.1 Although the study found that those randomized to the patch had lower time to hemostasis and ambulation, several potentially confounding factors need to be kept in consideration.

First, the vascular closure literature is replete with studies that depend on two of the softer endpoints in interventional cardiology: time to h...

The Different Patterns of Calcification of Acute Myocardial Infarction, Unstable Angina Pectoris and Stable Angina Pectoris

ABSTRACT: Background. Intravascular ultrasound (IVUS) enables the identification of calcification with more details and quantification of calcification, but there is not a proper method to quantify the calcification with IVUS. Previous IVUS studies used arc or length of calcium, respectively, to quantify calcification, but calcium is determined by a combination of arc and length. We devised a new method to quantify calcium as arc area (AA) in the present study...

Coronary calcification has long been known to reflect underlying atherosclerotic coronary artery disease. In fact, the presence of coronary calcification has become an important component of screening for coronary artery disease and the extent of calcification on electron beam computed tomography has been shown to correlate with prediction of future cardiovascular events.1,2

Intravascular ultrasound (IVUS), by virtue of its ability to image at high resolution, allows not only assessment of the location of coronary calcification, but also the number, depth, arc and length of calcified plaque...

ABSTRACT: Objective. To describe our institutional experience providing “hybrid” intraoperative stent therapy for pulmonary artery (PA) stenoses. Background. Surgical patch angioplasty, transcatheter stent therapy and intraoperative stent delivery are valuable treatment options for PA stenoses. The experience with intraoperative hybrid therapy has increased and new techniques and equipment have become available. Methods. This study involves a retrospective review of 20 patients with a median age of 5.1 years who underwent hybrid PA stent therapy between March 2003 and April 2008. Thirteen ...

ABSTRACT: The pathophysiology of takotsubo cardiomyopathy remains enigmatic. Here we attempted to define the link between the coronary arteries and the histopathological involvement of the left ven- tricle. We observed similarities and discrepancies between patients. All patients experienced stress prior to the event. We found a reduced coronary flow reserve in all patients and signs of hibernating my- ocardium on biopsy specimen. This raises a strong suspicion of stress- induced endothelial dysfunction with hibernating myocardium in the pathogenesis of this cardiomyopathy.

In the Setting of ST-Elevation Myocardial Infarction

ABSTRACT: Primary percutaneous coronary intervention (PCI) is an established reperfusion strategy in the treatment of acute myocardial infarction with ST-segment elevation (STEMI). Nevertheless, myocardial damage is not terminated immediately, even with successful primary PCI, which eliminates the epicardial occlusion. Despite the success of contemporary reperfusion therapy and effective restoration of epicardial coronary flow, many patients have suboptimal flow at the tissue level within the myocardium. Studies indicate that the...

A Potential Role for Enoxaparin

ABSTRACT: Unfractionated heparin (UFH) is currently given as the standard anticoagulant therapy in ST-elevation myocardial infarction (STEMI) patients, including those undergoing percutaneous coronary intervention (PCI). Recent data, however, have shown lower rates of death or recurrent myocardial infarction (MI) with the low-molecular-weight heparin (LMWH) enoxaparin compared with UFH in STEMI patients treated with thrombolytics, offsetting an increase in major bleeding. This review compares the use of enoxaparin with UFH in STEMI patients undergoin...

To Reduce Door-to-Balloon Time in ST-Elevation Myocardial Infarction Patients

ABSTRACT: Background. In ST-segment elevation acute myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI), all efforts must be made to improve door-to-balloon (DTB) times. This study was designed to assess the impact of electrocardiographic-guided immediate intervention (EGII) without performing a complete coronary evaluation on DTB times and clinical outcomes of STEMI patients treated with primary PCI. Methods. Consecutive STEMI patients undergoing primary PCI...

ABSTRACT: We discuss the case of a 71-year-old female patient who presented with findings suggestive of an acute myocardial infarction. Subsequent evaluation revealed an extrinsic cardiac mass encasing the left circumflex and right coronary arteries (RCA) which caused compression and spasticity of the RCA. Biopsy findings were consistent with a hematologic malignancy. Reports of extrinsic compression of epicardial coronary arteries are uncommon. Neoplasms, either primary cardiac tumors or metastatic disease, are a rare cause of extrinsic compression of coronary arteries.
