*  Coronary pacing during percutaneous transluminal coronary angioplasty. | Circulation
To avoid venous puncture, a new concept for standby cardiac pacing during percutaneous transluminal coronary angioplasty (PTCA) and diagnostic cardiac catheterization was developed. It uses an arterial guidewire as a unipolar pacing electrode with the second electrode attached to the skin. The system was tested in 25 coronary arteries of 22 patients undergoing PTCA and in the left ventricles of 10 patients undergoing diagnostic cardiac catheterization. Coronary pacing via the guidewire used for directing the balloon catheter was possible in all patients and in 24 of the 25 coronary arteries attempted. Maximum duration of pacing was 8 min. Threshold currents ranged from 1 to 15 mA (mean 5.7). Left ventricular pacing via the same wires or standard wires used for introduction of diagnostic or guiding catheters was possible in all patients and was maintained for up to 10 min. Threshold currents ranged from 1 to 7 mA (mean 3.9). ...

*  Cardiac Catheterization - Kadlec Regional Medical Center
Diagnostic Cardiac Catheterization (also called coronary angiography or coronary arteriography) is used to assist in diagnosing complex heart conditions. Cardiac angiography involves the insertion of a tiny catheter into the artery in the groin then carefully threading the catheter up into the aorta where the coronary arteries originate. Once the catheter is in place, a dye is injected which allows the cardiologist to see the size, shape, and distribution of the coronary arteries. These images are used to diagnose heart disease and to determine, among other things, whether or not surgery is indicated.. Interventional Cardiac Catheterization ( angioplasty ) utilizes the same basic principles as diagnostic catheterization and then uses advanced techniques to improve the heart's function. Proven extremely beneficial in eliminating blockages in the coronary arteries, interventional cardiology treatment ...

*  Tips From Other Journals - American Family Physician
The concept of diastolic heart failure has generated a fair amount of controversy, with some authorities questioning whether specific evidence of diastolic dysfunction has been found in patients diagnosed with this condition. Zile and colleagues described findings from diagnostic studies performed on a series of patients diagnosed with diastolic heart failure.. The study authors enrolled 47 patients scheduled for diagnostic cardiac catheterizations who had heart failure and normal left ventricular ejection fractions. These patients were compared with 10 control patients who had no evidence of heart failure but underwent catheterization for the evaluation of chest pain and were found to have normal coronary arteries and systolic function. During cardiac catheterization, a micromanometer was inserted into the left ventricle to measure precisely left ventricular pressures during diastole. Echocardiography was performed on all ...

*  A home-based exercise program for children with congenital heart disease following interventional cardiac catheterization:...
Congenital heart disease (CHD) is one of the most common structural abnormalities, occurring in 9 of every 1000 live births [1, 2]. Over the last three decades, dramatic changes have occurred in pediatric cardiac catheterization, and cardiac catheterization is now the main procedure for pediatric cardiac disease. In comparison with traditional cardiac surgical procedures (open heart surgery), therapeutic cardiac catheterization has several advantages, including being simpler and safer, and it is associated with an improved outcome [3]. Hence, pediatric therapeutic cardiac catheterization has increased recently because of numerous innovative catheter techniques, the increased number of persons and centers using these techniques, and the increased number of lesion types thought to be amenable to catheter therapy. It has been considered as the ...

*  ACS: A triad of troubles sets the stage for MI : Nursing made Incredibly Easy
ECG changes with NSTEMI are the same as with UA; however, cardiac biomarkers are positive. Elevated cardiac biomarkers indicate that plaque disruption has occurred with significant myocardial injury or infarct (necrosis).. The patient will likely undergo nonemergent diagnostic cardiac catheterization with possible percutaneous coronary intervention (PCI), such as angioplasty and/or stent placement. According to the American College of Cardiology (ACC) Foundation/American Heart Association (AHA) Taskforce on Practice Guidelines/Society for Cardiovascular Angiography and Interventions 2011 Guideline for Percutaneous Coronary Intervention, PCI to improve survival is reasonable in patients with UA/NSTEMI when an unprotected left main coronary artery is the culprit lesion and the patient isn't a candidate for coronary artery bypass grafting (CABG).. STEMI is confirmed when chest pain and associated symptoms occur with the presence of ST-segment ...

Diagnostic cardiac catheterization was performed within 2 h after echocardiography. Before contrast material was injected into the LV or coronary artery, LV pressure was obtained using a catheter-tipped micromanometer (SPC-454D, Millar Instrument Co., Houston, Texas) and recorded on a polygraph system (RMC-2000, Nihon Kohden Inc., Tokyo, Japan) and also on a digital data recorder (NR-2000, Keyence, Osaka, Japan). The offset of pressure waves obtained using a catheter-tipped micromanometer was adjusted to that obtained using a fluid-filled system. From the recorded pressure waves, the peak negative first derivative of left ventricular pressure (dP/dt) was determined, and then Tw was calculated using the method proposed by Weiss et al. (18). In the calculation of Tw, the following assumption is applied: a monoexponential curve fitting with LV pressure decay after the phase of peak negative dP/dt has a zero asymptote. This assumption may bring a possibility that Tw is dependent ...

*  ACROSS-Cypher Total Occlusion Study of Coronary Arteries 4 Trial - Full Text View - ClinicalTrials.gov
Despite remarkable advances in the procedural and clinical outcomes of percutaneous revascularization, chronically occluded coronary arteries remain a formidable challenge and unresolved dilemma in interventional cardiology. Although a TCO is identified in approximately one-third of diagnostic cardiac catheterizations, still an attempted revascularization accounts for less than 8% of all percutaneous coronary interventions (PCI). Such a disparity between their frequency and treatment not only underscores the technical and procedural frustrations associated with these complex lesions, but also the clinical uncertainties regarding clinical benefits with conventional TCO revascularization and the ongoing inadequacies of current PCI methods for sustaining restenosis-free patency following initial success.. Until recently, few clinical investigations have been performed to support clinical benefit of TCO revascularization. In addition to relief of symptomatic ischemia, ...

Background: In assessing left ventricular (LV) end-diastolic pressure (EDP) noninvasively, not only left atrial (LA) function but also LV compliance should be considered. Recently developed tissue strain imaging (TSI) enables us to evaluate myocardial extensibility during diastole. Accordingly, we investigated whether LVEDP could be predicted using a new parameter, ie, LA dimension at LV end-systole (LADs) corrected by LV diastolic myocardial strain (%thinning from end systole).. Methods: Study subjects consisted of 112 patients collected from our data base of 322 patients underwent TSI and diagnostic cardiac catheterization on the same day. In all patients, leftventriculography and LVEDP measurement were performed. Fifty-six had prior myocardial infarction (MI). Thirty-nine were anterior MI, 11 inferior and 6 were anterior plus inferior wall MI. Fourteen of those had a LV apical aneurysm. The remaining 56 had no localized LV wall motion abnormality. Peak radial strain ...

The cardiac catheterization procedure takes between 30 minutes to an hour. You will not be completely asleep during the procedure, because it will be necessary to talk to you during the test. There will be several staff members in the lab that will assist the physician. A Coronary angiography is usually done along with cardiac catheterization. A Coronary Angiogram is a test that uses X-rays to help your doctor find narrowing or blockage in one or more of your coronary arteries. To perform an angiogram, your physician will numb your groin with medicine, The medicine may burn as it begins to work but then you should have no pain for the rest of the exam. A small thin tube called a catheter will be threaded through a large vessel in your leg known as the femoral artery. It will follow that artery to your heart. Some physicians have been specially trained to use the wrist (radial) artery, which is possible in certain patients and has an ...
