BACKGROUND: Most cardiac catheterizations are performed via femoral artery access. Reported rates of both peripheral vascular complications and success rates for the use of manual and mechanical compression techniques to achieve femoral artery hemostasis after cardiac catheterization vary. OBJECTIVE: To determine is use of a mechanical clamp is as effective as standard manual pressure for femoral artery hemostasis after cardiac catheterization. METHODS: Subjects consisted of 720 patients from 2 community hospitals who had elective diagnostic cardiac catheterization via the femoral artery. The control group (n=343) received manual compression for hemostasis; the study group (n=377) received mechanical compression. Standard protocols were used for the 2 compression techniques. Pressure was applied for a minimum of 10 minutes for 5F and 6F sheaths and catheters and for a minimum of 15 minutes for 7F and 8F sheaths and catheters. Prospective data were collected and analyzed for each patients, including sheath or catheter size, blood pressure, height, weight, age, time from administration of local anesthetic to successful cannulation of the femoral artery, anticoagulation status, total compression time, physician performing the catheterization procedure, nurse or technician who obtained hemostasis, and complications. In follow-up, patients were asked site-specific and functional status questions 1 to 2 days after the catheterization procedure and again 3 days after the catheterization procedure. RESULTS: Data were analyzed by using frequency distributions, measures of central tendency, and measures of variability. Only 1 difference between the 2 groups was significant: manual compression time was 14.93 +/- minutes, whereas mechanical compression time was 17.13 +/- minutes. CONCLUSION: Mechanical compression is as effective as manual compression for femoral artery hemostasis after cardiac catheterization.

Cardiac catheterization and coronary angiography are both key components to routine cardiology practice. This new edition of Cardiac Catheterization and Coronary Intervention has been fully updated since the first edition, with new sections on primary percutaneous coronary intervention, trends in vascular access, bioabsorbable stents, optical coherence tomography, and more. Filled with over 150 clinical images and schematic illustrations, the handbook is an accessible ‘how-to’ guide, designed to demystify complex cardiac catheterization investigations. Expanded to reflect developments in practice, this new edition also introduces a new chapter on the multidisciplinary team and their roles and responsibilities from pre- to post-procedural care and relevant training requirements. It contains detailed instructions on how to perform a comprehensive left and right heart catheterization procedure, choosing the correct catheter for coronary and graft angiography, and how to perform a diagnostic coronary angiogram and interpret the subsequent findings.

Abstract We report a 62-year-old man with a past medical history of dyslipidemia, paranoid schizophrenia and permanent atrial fibrillation. A ATTE performed at his district hospital revealed rheumatic mitral valve disease with double lesion: severe regurgitation and mild stenosis, plus moderate tricuspid regurgitation and a mean PAP of 32mm Hg. Cardiac catheterization showed no abnormalities of the coronary arteries. He was transferred to our hospital and scheduled for mitral valve replacement and tricuspid ring valvuloplasty. Preoperative transesophageal echocardiography showed an abnormal subvalvular mitral apparatus, with false tendons and multiple papillary muscles, resembling a hammock mitral valve. Most cordae tendinae arose from a single dominant papillary muscle at a posterior medial region, which provoke severe mitral regurgitation due to coaptation defect and mild subvalvular mitral stenosis. It could also be appreciated hypertrabeculation in the lateral medial, basal and apical segments. This suggested no-compaction cardiomyopathy associated with hammock mitral valve. Left ventricular systolic function was preserved. No evidence of rheumatic mitral valve disease was found in transesophageal echocardiographic study performed at our hospital. On the 30th April 2019 he underwent mechanic mitral valve replacement (Bicarbon 29mm) and tricuspid ring valvuloplasty (Edwards Physio 32mm) surgery. Once the patient was weaned from cardiopulmonary bypass, severe left ventricle systolic dysfunction ensued, predominantly localized in the anterior, inferior septal, inferior lateral basal and medial segments. Apical segments had preserved mobility An adrenalin infusion prior weaning from CBP was initiated. Preserved mobility of the mitral prosthesis discs was observed. The patient developed cardiogenic shock in spite of high doses of dobutamin and adrenaline infused. IACB was implanted with 1:1 assistance. The patient was transfered to the hemodynamic room in order to rule out coronary complications. Cardiac catheterization showed no significant angiographic lesions. During the first postoperative hours, the patient was stabilized allowing progressive lowering of the drugs (adrenaline, dobutamine). TTE showed normally functioning prosthetic mitral valve and preserved left ventricle systolic function. An MRI was performed demostrating no-compaction cardiomyopathy Conclusion This case report describes a rare presentation of simultaneous ocurrence of hammock mitral valve and no-compaction cardiomyopathy. Perioperative left ventricle dysfunction in no-compaction cardiomyopathy is related to subendocardial ischemia caused during extracorporeal circulation in the multiple prominent ventricular trabeculations with deep intertrabecular recesses corresponding to non-compacted myocardium .This must be taken account in those patients with no-compaction cardiomyopathy scheduled for cardiac surgery in order to take preventive measures.

A Cardiac function is evaluated quantitatively by analyzing a shape change of the heart wall boundaries in angiographic images. To begin with, a boundary detection of end systolic left ventricle (ESLV) and end diastolic left ventricle (EDLV) is essential for the quantitative analysis of the cardiac function. Conventional methods for the boundary detection are almost semi-automatic, and a knowledgeable human operator’s intervention is still required. Manual tracing of the boundaries is currently used for subsequent analysis and diagnosis. However, these methods do not cut excessive time, labor, and subjectivity associated with manual intervention by a human operator. Generally, EDLV images have noncontiguous and ambiguous edge signal on some boundary regions. In this paper, we propose a new method for an automated detection of left ventricle (LV) boundaries in noncontiguous and ambiguous EDLV images. The proposed boundary detection scheme is based on a priori knowledge information and is divided into two steps. The first step is to detect EDLV boundary using ESLV boundary. The second step is to correct the detected EDLV boundary using the left ventricle (LV) shape information. We compared the proposed method with the manual method to detect the EDLV boundary. And through the experiments of the proposed method, we verified the usefulness of this method.

We report a case of cardiac catheterization that was done entirely by accidentally accessing the inferior epigastric artery (IEA) through an unintentional puncture of the U-shaped portion of the inferior epigastric artery. Luckily the patient did not have any trauma to the IEA and was d/c home with no complications. A 48-year-old female with history of hypertension and CAD S/P left circumflex stent many years ago who presented to our facility with persistent crescendo angina for which decision was made to proceed with LHC. The cardiac catheterization showed no significant CAD with patent stent so it was decided that there is no further intervention needed. Femoral angiogram was done and showed that the stick was high and the tip of the sheath was about to come out of the CFA; at the same time, it came into our minds that the sheath could be passing through the IEA by sticking the U portion of the IEA, but due to the high risk, an immediate access was obtained through the contralateral groin then a balloon over the wire was passed beyond the original sheath tip, then the sheath was slowly pulled back while contrast was injected. Angiogram showed that the sheath was inserted through the U-shaped portion of the IEA. Conclusion. Ultrasound guidance should be the first-line standard for arterial access in any cardiac catheterization procedure. US is a proven tool that can increase success and decrease complications in a wide variety of vascular access procedures.
