Validation of high-resolution echocardiography and magnetic resonance imaging vs. high-fidelity catheterization in experimental pulmonary hypertension
High-frequency echocardiography and high-field-strength magnetic resonance imaging (MRI) are new noninvasive methods for quantifying pulmonary arterial hypertension (PAH) and right ventricular (RV) hypertrophy (RVH). We compared these noninvasive methods of assessing the pulmonary circulation to the gold standard, cardiac catheterization (micromanometer-tipped catheters), in rats with monocrotaline-induced PAH and normal controls. Closed-chest, Sprague-Dawley rats were anesthetized with inhaled isoflurane (25 monocrotaline, 6 age-matched controls). Noninvasive studies used 37.5-MHz ultrasound (Vevo 770; VisualSonics) or a 9.4-T MRI (Bruker BioSpin). Catheterization used a 1.4-F micromanometer-tipped Millar catheter and a thermodilution catheter to measure cardiac output (CO). We compared n......

Supravalvular aortic stenosis surgical repair using modified Sousa's technique
Relato de uma paciente de sete anos apresentando progressiva intolerância ao esforço. A criança apresentava taquicardia e sopro pansistólico de maior intensidade no foco aórtico. O ecocardiograma evidenciava hipertrofia ventricular esquerda e estenose aórtica supravalvar com gradiente sistólico de 190 mmHg. A angioressonância e o cateterismo cardÃaco confirmaram o diagnóstico, sugerindo estenose do óstio da artéria coronária esquerda. A correção foi realizada modificando a técnica descrita por Sousa. A evolução pósoperatória transcorreu sem intercorrências, com gradiente pós-operatório de 23 mmHg e boa mobilidade da valva aórtica.Report of a patient with seven years old and effort intolerance progressing. The child had tachycardia, pansystolic murmur in the aortic f......

Utility of a bedside acoustic cardiographic model to predict elevated left ventricular filling pressure
Conclusion
These data demonstrate that the four-variable model predicts elevated filling pressure at the bedside with high specificity and an intermediate LR+. With improvements in sensitivity and further prospective validation of this model in a cohort of emergency department patients with undifferentiated dyspnoea this may be a useful bedside diagnostic modality.

Takotsubo cardiomyopathy presenting as postoperative atrial fibrillation
We present the case of a 78-year-old lady, post gynecological surgery, presenting with palpitations and ECG confirming fast atrial fibrillation. Despite spontaneous cardioversion, she went on to develop ECG changes and cardiac enzyme elevations suggestive of an acute myocardial infarction. Cardiac catheterization was performed and confirmed the diagnosis of TC. It highlights an atypical presentation of TC, which can present initially as an arrhythmia in the postoperative phase as a consequence of the supraphysiological effects of elevated circulating plasma catecholamines. It reiterates the importance of prompt diagnosis and treatment to prevent cardiac decompensation in a condition poorly understood. (Source: Journal of Postgraduate Medicine)...

Sewing needles embedded in the cardiac interventricular septum and chest wall
A 61-year-old woman with a history of anxiety and depression, status post left mastectomy, and with resultant diminished sensation in her left chest wall presented with a 2-month history of left-sided chest pain and shortness of breath. Chest roentgenograms revealed the presence of thoracic foreign bodies consistent with sewing needles (). Computed tomographic scanning with 3-dimensional reconstruction demonstrated the location of one the needles to be in the cardiac interventricular septum and right ventricular apex; the remaining 2 additional needles were embedded in her left chest wall (, A). The patient attributed the presence of these needles to accidental penetration while sleeping with her sewing materials nearby. Transthoracic echocardiographic analysis showed the needle as a linea......

Drug-eluting Stents Confirmed Safe, Effective For Long-term Use
Researchers at the Rabin Medical Center in Israel have determined that the use of drug-eluting stents (DES) improves the long-term clinical outcome for patients undergoing percutaneous coronary intervention (PCI), commonly known as angioplasty. Results of this study appear in the September issue of Catheterization and Cardiovascular Interventions, a journal published by Wiley-Blackwell on behalf of The Society for Cardiovascular Angiography and Interventions. PCI is used to treat coronary artery disease and is one of the most common medical procedures... (Source: Health News from Medical News Today)...

Pulmonary arterial hypertension: an update on diagnosis and treatment.
Authors: Stringham R, Shah NR
Pulmonary arterial hypertension is defined as a mean pulmonary arterial pressure greater than 25 mm Hg at rest or 30 mm Hg during physical activity. Pulmonary arterial hypertension is classified into subgroups, including idiopathic, heritable, and pulmonary arterial hypertension associated with other conditions. A detailed history, thorough physical examination, and most importantly, a high index of suspicion are essential to diagnosis. Evaluation includes echocardiography and exclusion of other causes of symptoms. Targeted laboratory testing can help identify the subgroup of pulmonary arterial hypertension. Right heart catheterization is required to confirm the diagnosis. Standard treatment options include oral anticoagulation, diuretics, oxygen supplemen......

[Ultrasound-guided supraclavicular subclavian vein catheterization: A novel approach in children.]
Authors: Attof R, Rhondali O, Combet S, Chassard D, De Queiroz M
The subclavian vein (SCV) is often the preferred site for long-term central venous catheterization in children. It has many advantages over the internal jugular vein. But with the classical landmark technique for SCV catheterization the ultrasound-guidance technique is usually not suitable, because of the clavicle (a bright hyperechoic structure with an acoustic shadow beneath it). Because the SCV can easily be visualized via a supraclavicular approach, we developed a useful ultrasound-guided approach for SCV catheterization in infants and children.

Emergency bypass post percutaneous atrial ablation: a case report.
Authors: Hargrove M, Marshall C, Jahanjir S, Hinchion J
A 34-year-old male undergoing percutaneous atrial ablation procedure for paroxysmal fibrillation required emergency sternotomy for cardiac tamponade. The patient had been anticoagulated and had received plavix and aspirin prior to and during the ablation procedure. Seven units of red cell concentrate had been transfused in the cardiac catherisation laboratory. On arrival in theatre, the patient was hypotensive, but was awake on induction of anaesthesia. No recordable blood pressure with non-invasive monitoring was observed. A sternotomy was immediately performed and, on evacuation of the pericardium, a bleeding site was not visible. The patient was commenced on cardiopulmonary bypass. Bleeding site was identified and the defect cl......

X-Ray Dose from Pediatric Cardiac Catheterization: A Comparison of Materials and Methods for Measurement or Calculation
Abstract Pediatric cardiac catheterization procedures have the potential to transmit high X-ray doses, which may lead to acute effects
or latent skin reactions. Direct measurement of radiation dose was facilitated using nanodot dosimeters and radiochromic film.
Direct measurement results were compared with vendor-listed dosimetry and calculation using phantom data. Vendor-listed data
demonstrated a wide discrepancy with measured data, whereas the calculation reproducibly overestimated the actual dose. A
simple formula was derived to calculate the dose using fluoroscopy time, cine frame quantity and average cine mA in a biplane
environment.

The Snow-Shoveler's ST Elevation Myocardial Infarction
In conclusion, these findings suggest that in typically sedentary individuals with cardiac risk factors or histories of coronary artery disease, snow shoveling may trigger ST elevation myocardial infarction and therefore should be avoided. This may be most critical in patients with histories of coronary stent placement, considering that these findings suggest that snow shoveling may precipitate subacute stent thrombosis.

Coronary Calcification and Coronary Artery Disease
Gottlieb et al. () report computed tomography (CT) calcium scores in 291 patients (73% male) being referred for coronary angiography. The majority (95%) had either intermediate or high pre-test probability of coronary disease, and 42 (19.6%) had presented as emergencies with unstable angina. The authors report a surprisingly low sensitivity of only 45% for a calcium score of 0 to predict the absence of â¥50% lesions, that led your editorialist () to question the incremental value of calcium scoring for diagnosing coronary artery disease (CAD). Yet, as stated in the editorial, the value of any diagnostic test is critically dependent on the population in which it is applied. Calcium scoring has been recommended as a useful rule-out in patients with a low probability of CAD, based on meta-an......

MRI for detection of anomalous pulmonary venous drainage in patients with sinus venosus atrial septal defects
Abstract Purpose of this survey was to estimate the value of MRI for the assessment of the anatomical and functional features of sinus
venosus atrial septal defect (SVD). This prospective study included 13 surgically proven cases of SVD out of 81 subjects submitted
to MRI due to inconclusive transthoracic echocardiography (TTE) or suspicion of high intracardiac and/or extracardiac shunt
volumes based on echocardiographic findings. MRI examination included cine SSFP sequences, contrast-enhanced 3D gradient-echo
(GE) sequences for MR angiography (MRA) and phase-contrast flow-measurements. MRI revealed nine patients with a superior and
four with an inferior SVD. Anomalous pulmonary venous drainage (APVD) was observed only in subjects with a superior SVD, and
it was right-side......

ARMYDA-5 PRELOAD trial shows in-laboratory clopidogrel loading as effective as pre-loading in patients undergoing PCI
Source: J Am Coll Cardiol
Area: News
According to research published in the Journal of the American College of Cardiology, outcomes of percutaneous coronary intervention (PCI) are just as good when a loading dose of clopidogrel is given in the cath lab as when it's given 4 to 8 hours beforehand.
Researchers in the Antiplatelet therapy for Reduction of MYocardial Damage during Angioplasty (ARMYDA-5 PRELOAD) evaluated the safety and efficacy of in-laboratory (in-lab) 600-mg clopidogrel loading pre-PCI versus routine 6-hour pre-load.
A total of 409 patients (39% with acute coronary syndrome) were randomised to receive a 600-mg clopidogrel loading dose 4 to 8 hours before PCI (pre-load group, n = 204) or a 600-mg loading dose given in the catheterisation lab after corona......

Successful Vaginal Delivery of a Pregnant Woman with Cantrell's Pentalogy.
Authors: Moon KY, Choe SA, Park CW, Park JS, Jun JK, Syn HC
Cantrell's Pentalogy is a rare condition that consists of defects involving the abdominal wall, lower sternum, anterior diaphragm, pericardium, and heart. In the literature to date, pregnant women with Cantrell's Pentalogy have not been discussed. We performed successful vaginal delivery of a 23-yr-old nulliparous, primigravid woman who had been diagnosed with this condition. Diagnosis was based on cardiac catheterization, angiography, and echocardiogram, and abdominopelvic CT. Vaginal delivery may be an option for women with Cantrell's Pentalogy and may be attempted with caution.
