REVIEW
Rolf Dörr, Reinhardt Sternitzky
In Germany, every second left heart catheterization has no immediate interventional or surgical consequence. One main reason for this limited quality of indication of many left heart catheterizations is presumably the inaccuracy of preinvasive testing that is mainly based on clinical evaluation and exercise ECG in Germany. However, exercise electrocardiography has several limitations. The central issues are the inability to exercise in many, especially elderly patients, and the missing interpretability of the stress ECG in cases with already pathological rest ECG...

JOURNAL ARTICLE
Abdul Basit, Raja Nazir, Harvey Hahn
A 69-year-old male presented with inferior wall ischemia. Transradial coronary angiogram with an Optitorque Jacky shape catheter showed unobstructed coronary arteries (Terumo Medical Corporation). Left ventriculography was complicated with myocardial and pericardial contrast staining. The catheter was pulled back. The patient experienced sharp chest pain that resolved in 20 minutes. Stat transthoracic echocardiogram was unremarkable. The patient remained hemodynamically stable. Transthoracic echocardiogram the next morning revealed trivial pericardial effusion...

OBJECTIVES: To evaluate procedural and safety metrics of transradial (TR) versus transfemoral (TF) cardiac catheterization (CATH) and percutaneous coronary interventions (PCI) during a complete institutional transition from TF to TR as the preferred access. BACKGROUND: The TR approach has been shown to reduce complications compared to TF for CATH and PCI, but concerns of longer procedure times have limited utilization in the United States. METHODS: 4,172 consecutive CATH and PCI procedures were performed (2,665 TF; 1,507 TR) at Wake Forest Baptist Medical Center from January 2009 to November 2010...

BACKGROUND: Noninvasive coronary angiography with the use of multislice computed tomography (CT) scanners is feasible with high sensitivity and negative predictive value; however, the radiation exposure associated with this technique is rather high. We evaluated coronary angiography using whole-heart 320-row CT, which avoids exposure-intensive overscanning and overranging. METHODS AND RESULTS: A total of 30 consecutive patients with suspected coronary artery disease referred for clinically indicated conventional coronary angiography (CCA) were included in this prospective intention-to-diagnose study...

REVIEW

Immediate coronary catheterization is mandatory for high risk patients with typical chest pain in the emergency department (ED). In contrast, in ED patients with acute chest pain but low to intermediate risk, traditional management protocol includes serial ECG, cardiac troponins and radionuclide perfusion imaging. However, this protocol is time-consuming and expensive, and definite treatment of unstable angina is often delayed. Due to advances of multi-detector CT (MDCT) technology, dedicated coronary CT angiography provides the potential to rapidly and reliably diagnose or exclude acute coronary syndrome in ED patients with acute chest pain...

BACKGROUND: Intravascular contrast agents presently used in modern digital catheter laboratories during cardiac catheterization are superior to older agents as regards patient tolerance. There are, however, significant differences between these agents. PURPOSE: The aim of this study was to determine the incidence of early (< 24 hours) and late (> 24 hours to 7 days) reactions to 2 contrast agents currently used during cardiac catheterization: iopamidol 340 (Niopam) and iobitridol 350 (Xenetix)...

Joachim Hebe
The role of surgery and radiofrequency current ablation for the treatment of tachycardias in patients with congenital heart disease The use of radiofrequency current application as a treatment strategy has stimulated a revolution in our understanding of tachycardia mechanisms. The extension of its use to patients with congenital heart defects and tachyarrhythmias has opened the door to new treatments with known success rates and known risks for mortality and morbidity. Antiarrhythmic surgery aims to dissect or excavate a responsible substrate and is especially worth considering if cardiac surgery is being undertaken for other reasons...

OBJECTIVES: To deternine whether there are racial differences in patients' health-related attitudes, beliefs, and experiences regarding invasive cardiac procedures, and to develop psychometrically and conceptually valid scales and single items to assess these dimensions. METHODS: A survey was designed and administered to 854 white and black patients with ischemic heart disease at five VA medical centers. Patients were queried about the domains proposed to be important to treatment decision making by the Health Decision Model: sociodemographic characteristics, social interactions, health care experiences, patient preferences for care, knowledge about diseases and potential treatments, and health beliefs...

Since 1992, 46 patients have undergone the Ross procedure. Of these, a pulmonary homograft was used for reconstruction of the RVOT in 16, and a tailored heterologous or autologous pericardial roll tube in 9. In the remaining 21, the autologous tissues were used as a posterior wall of the channel, placing another patch (bearing a monocusp in 14) anteriorly. All the patients survived the procedure. Reoperation has been needed thus far in one for infection of the prosthetic patch placed at the right ventricular outflow tract, and catheter intervention in 2 for mild obstruction across the channel...

OBJECTIVE: Clinical interest has recently emerged in a new technique of heart transplantation with bicaval and pulmonary venous anastomosis. This technique is thought to improve left heart function and reduce thromboembolism. We have used this technique systematically since 1993. We compared the patients transplanted before September 1993 with the standard technique and the patients transplanted with the new technique. METHODS: A total of 135 patients were transplanted at our institution from 1987 to 1995, 100 with the standard technique and 35 with the new technique...

A double-blind randomized study was performed in 49 patients to compare the hemodynamic changes induced by two contrast agents: non-ionic low osmolar lomeprol 350 (IO, n = 25) and ionic high osmolar Diatrizoat 370 (DIA, n = 24). We observed significant changes in hemodynamic parameters after laevocardiography with DIA: a decrease in LVSP from 125 +/- 14 to 113 +/- 14 mmHg, a decrease in mean aortic pressure from 96 +/- 9 to 84 +/- 10 mmHg and in max dp/dt from 2086 +/- 628 to 1861 +/- 654 mm Hg/sec. LVEDP increased from 13 +/- 5 to 17 +/- 6 mmHg and cardiac output from 5...

The purpose of this study was to evaluate the incidence of ventricular ectopy and catheter movement during left ventriculography with a new 5F halo angiographic catheter that has a unique helical-tip design unlike the design of standard 5F and 6F pigtail catheters. The pigtail catheter is presently preferred for left ventriculography, although its use is associated with a high incidence of ventricular ectopy, which often limits precise interpretation of data. In this study, 155 patients (in 145 unpaired and 10 paired studies) underwent left ventriculography during diagnostic cardiac catheterization...

In the standard precordial echocardiographic imaging planes, there is frequent dropout of atrial septal echoes in the region of the fossa ovalis that can be minimized by use of the subcostal imaging approach. The diagnostic sensitivity of this approach was reviewed in 154 patients (mean age 31 years, range 2 months to 74 years) with documented atrial septal defect in whom a satisfactory image of the atrial septum could be obtained. Subcostal two-dimensional echocardiography successfully visualized 93 (89%) of the 105 ostium secundum atrial septal defects, all 32 (100%) ostium primum defects and 7 (44%) of the 16 sinus venosus defects...

PURPOSE: Contrast-induced renal dysfunction has been reported to occur in 15% to 42% of patients with underlying azotemia, but there is disagreement as to whether its incidence is reduced by limiting the amount of contrast material. To adjust the amount of contrast material to the severity of azotemia, we have utilized the following formula to calculate a contrast material "limit" in patients with renal disease: Contrast material limit = (formula; see text) PATIENTS AND METHODS: Over a 10-year period, 115 patients (53 men, 62 women, aged 61 +/- 11 [mean +/- SD] years) with renal dysfunction (baseline serum creatinine level greater than or equal to 1...

REVIEW
M R Franz
MAP recordings have been at the cradle of cardiac electrophysiology but only recently, through safer and simpler technology, have gained wider access to clinical electrophysiology. In contrast to conventional electrode catheter recordings, MAP recording devices provide precise information not only of the local activation time but of the entire local repolarization time course as well. Although the MAP does not reflect the absolute amplitude or upstroke velocity of transmembrane action potentials, it delivers highly accurate information on the action potential duration and configuration, including early afterdepolarizations as well as relative changes in transmembrane diastolic and systolic potential changes...

The cardiocirculatory effects of the commonly used parenteral analgesics, morphine sulfate 15 mg, meperidine hydrochloride 100 mg and pentazocine 60 mg, each administered intravenously, were compared in 12 patients with acute myocardial infarction during cardiac catheterization and by echocardiogram. No untoward hemodynamic effects occurred following the administration of morphine or meperidine. In contrast, pentazocine produced significant (p less than 0.01 to less than 0.05) increases in systemic and pulmonary arterial pressures, left ventricular filling pressure, systemic vascular resistance, and systolic and diastolic dimensions; and decreases in left ventricular ejection fraction and mean velocity of circumferential fiber shortening...
