BACKGROUND: Transradial access (TRA) emerged in the last two decades as a valid alternative to the standard transfemoral access (TFA) for cardiac catheterization and percutaneous coronary intervention (PCI). Due to contrasting results, the penetration and uptake of TRA in real-world clinical practice has been slow and still limited to high experienced center. METHODS: We performed an updated systematic review and study-level meta-analysis of randomized controlled trials (RCTs) that investigated the efficacy and safety of TRA versus TFA for PCI in patients with ACS...

The radial artery has been increasingly used for its favorable safety profile. However, no conclusive data are available on the optimal sheath size. In particular, it is seemingly difficult to weight both advantages and disadvantages of narrower versus larger sheaths size. Despite several studies were performed to compare the use of 6-Fr to the smaller 5-Fr sheaths, these were mostly small, single center-studies, yielding various results.We performed a comprehensive meta-analysis of all available studies comparing the use of 5-Fr versus 6-Fr sheaths in coronary procedures through the TRA...

OBJECTIVES: To assess the accuracy and risk of substituting cardiac computed tomography for cardiac catheterization in select patients for evaluation of anatomy before second-stage single ventricle palliation. METHODS: This is a retrospective review of consecutive diagnostic cardiac catheterization (n=16) and computed tomography studies (n=16) performed before second-stage single ventricle palliation from March 2010 to July 2012 at a single institution. Risk (anesthesia, vascular access, contrast, and radiation exposure), accuracy, and postoperative course were compared...

There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and retrograde approaches as dictated by procedural factors. Antegrade wire escalation with intimal tracking remains the preferred initial strategy in short CTOs without proximal cap ambiguity. More complex CTOs, however, usually require either a retrograde or an antegrade dissection re-entry approach, or both...

Transcatheter aortic valve replacement (TAVR) as well as thoracic and abdominal endovascular aortic repair (TEVAR and EVAR) rely on accurate pre- and postprocedural imaging. This review article discusses the application of imaging, including preprocedural assessment and measurements as well as postprocedural imaging of complications. Furthermore, the exciting perspective of computational fluid dynamics (CFD) based on cross-sectional imaging is presented. TAVR is a minimally invasive alternative for treatment of aortic valve stenosis in patients with high age and multiple comorbidities who cannot undergo traditional open surgical repair...

OBJECTIVES: To evaluate the cost effectiveness of diagnostic cardiac catheterizations (CATH) and coronary interventions (PCI) performed using radial artery (RA) access compared to femoral artery (FA) access. BACKGROUND: CATH and PCI performed from the RA reduce access site complications compared to FA, but can increase procedure duration, and equipment and contrast use. Whether resulting increases in utilization costs are offset by reduced costs of complications is uncertain...

Primary angioplasty of the culprit coronary artery lesion is the preferred reperfusion strategy for ST-elevation myocardial infarction (STEMI) when timely access to a catheterization laboratory is available. The presence of multi-vessel disease (MVD) in patients undergoing primary PCI is common, occurring in about 40 %-50 % of patients. The presence of MVD in patients who have undergone successful primary PCI substantially increases the risks of mortality and major adverse cardiac events, such as reinfarction or need for urgent revascularization...

OBJECTIVES: In transcatheter aortic valve implantation (TAVI), assessment of the aortic annulus is mandatory. We sought to investigate the correlation between trans-oesophageal echocardiography (TEE) and multi-detector computed tomography (MDCT) for annulus diameter assessment before TAVI. METHODS: A total of 122 patients (67 male, mean age 84 ± 6 years) underwent MDCT and TEE for TAVI planning. In TEE annulus diameters were obtained in a long-axis view at diastole...

BACKGROUND: Older age, as a factor we cannot affect, is consistently one of the main negative prognostic values in patients with acute myocardial infarction. One of the most powerful factors that improves outcomes in patients with acute coronary syndromes is the revascularization preferably performed by percutaneous coronary intervention. No data is currently available for the role of age in large groups of consecutive patients with PCI as the nearly sole method of revascularization in AMI patients...

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...

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...

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)...

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...

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...
