  • Subendocardial stress in pre-eclampsia. [Case Reports]
    Ann Noninvasive Electrocardiol. 2020 Jun 05 [Online ahead of print]Tran T, Farasat M, Krantz MJ
  • A primigravida 26-year-old woman who had developed pre-eclampsia with malignant hypertension at 30 weeks of gestation suffered acute myocardial infarction two days postpartum. Electrocardiogram demonstrated diffuse ST-segment depression suggestive of subendocardial ischemia. Echocardiography demonstrated focal asymmetric left ventricular hypertrophy, with a characteristic "basal septal bulge", an…
  • Imaging of Atrioventricular Nodal Conduction Tissue in Porcine Hearts Using Optical Coherence Tomography. [Journal Article]
    J Innov Card Rhythm Manag. 2019 Jun; 10(6):3675-3680.Kilinc OU, Zhao X, … Rollins AM
  • Optical coherence tomography (OCT) employs near-infrared light to image the microstructure of different tissues. Clinically, it has been used to image the walls of coronary arteries. In research settings, one of the applications for OCT is visualizing endocardial and subendocardial structures. The present experiment sought to determine whether OCT can identify native conduction tissues in adult p…
  • A de Winter electrocardiographic pattern caused by left main coronary artery occlusion: A case report. [Journal Article]
    J Int Med Res. 2020 May; 48(5):300060520927209.Zhan ZQ, Li Y, … Han LH
  • A de Winter electrocardiographic (ECG) pattern comprising precordial junctional ST depression followed by tall, positive symmetrical T waves in leads V1/V2 to V4/V6 is often concomitant with ST elevation in lead aVR. This finding strongly suggests proximal left anterior descending coronary artery occlusion. We described a patient who had the de Winter ECG pattern in leads V2 to V4 by acute left m…
  • Myocardial Contrast Uptake in Relation to Coronary Artery Disease and Prognosis. [Journal Article]
    Ultrasound Med Biol. 2020 May 18 [Online ahead of print]Kim H, Kim IC, … Hur SH
  • During left ventricular opacification (LVO), myocardial contrast uptake (MCU) is frequently observed, but its clinical implication is uncertain. We aimed to investigate the diagnostic performance of MCU and its prognostic value in known or suspected coronary artery disease (CAD). Contrast echocardiography was retrospectively analyzed in 457 patients who had previous coronary angiography <12 mo be…
  • Congenital systemic venous drainage obstruction: A case report. [Case Reports]
    J Card Surg. 2020 May 13 [Online ahead of print]Sarmento JA, Granja S, … Moreira J
  • Vena cava anomalies are rare congenital defects due to incorrect development during fetal life, ranging from minor asymptomatic anatomic variations to complex life-threatening abnormalities. Echocardiography plays a fundamental role in the diagnosis, with advanced imaging techniques allowing detailed anatomic delineation. Invasive cardiology techniques are a promising therapeutic approach, but su…
  • Postmortem Computed Tomography and Magnetic Resonance Imaging of an Abdominal Gunshot Wound. [Journal Article]
    Am J Forensic Med Pathol. 2020 Jun; 41(2):119-123.Gascho D, Bolliger SA, … Tappero C
  • The use of postmortem computed tomography (CT) has been described in many articles concerning gunshot injuries. Postmortem magnetic resonance imaging (MRI) for better assessment of soft tissue injuries has also been mentioned in the literature, albeit much less often. The use of postmortem MRI for abdominal gunshot wounds has not been previously presented in the literature. The present case repor…
  • Balanced Biventricular Assist Versus Extracorporeal Membrane Oxygenation in Cardiac Arrest. [Journal Article]
    ASAIO J. 2020 Mar 24 [Online ahead of print]Packer EJS, Slettom G, … Tuseth V
  • Mechanical assist devices in refractory cardiac arrest are increasingly employed. We compared the hemodynamics and organ perfusion during cardiac arrest with either veno-arterial extracorporeal membrane oxygenation (ECMO) or biventricular assisted circulation combining left- and right-sided impeller devices (BiPella) in an acute experimental setting. Twenty pigs were randomized in two equal group…
  • Troponins in Heart Failure - a Perpetual Challenge. [Editorial]
    Maedica (Buchar). 2019 Dec; 14(4):371-377.Gherasim L
  • Increased troponin levels in HF are a frequent and significant finding, as it strongly correlates with the underlying pathogenic mechanisms, diagnosis and prognosis. The advent of hs-cTn testing, as opposed to conventional troponin testing, led to additional difficulties in result interpretation. Most frequently, though not exclusively, increased cTn levels in acute or chronic failure is correlat…
  • Feasibility of selective cardiac ventricular electroporation. [Journal Article]
    PLoS One. 2020; 15(2):e0229214.Sugrue A, Vaidya VR, … McLeod CJ
  • CONCLUSIONS: PEF provides a novel, safe method for non-thermal acute modulation of the Purkinje fibers without significant injury to the underlying myocardium. Future optimization of this energy delivery is required to optimize conditions so that selective electroporation can be utilized in humans the treatment of cardiac disease.
  • Effects of myocardial function and systemic circulation on regional coronary perfusion. [Journal Article]
    J Appl Physiol (1985). 2020 May 01; 128(5):1106-1122.Namani R, Lee LC, … Kassab GS
  • Cardiac-coronary interaction and the effects of its pathophysiological variations on spatial heterogeneity of coronary perfusion and myocardial work are still poorly understood. This hypothesis-generating study predicts spatial heterogeneities in both regional cardiac work and perfusion that offer a new paradigm on the vulnerability of the subendocardium to ischemia, particularly at the apex. We …
  • Myocardial damage of the entire ventricular region in a patient with acute myocardial infarction. [Case Reports]
    Asia Ocean J Nucl Med Biol. 2020 Winter; 8(1):69-73.Kawamata H, Kawasaki T, … Matoba S
  •  Technetium-99m-pyrophosphate (99mTc-PYP) has been used, in combination with thallium-201, to estimate the site and extent of myocardial infarcts. We report a case of acute myocardial infarction with severe coronary disease in which the distribution of 99mTc-PYP was extensive. A 78-year-old man presented with dyspnea, and a diagnosis of non-ST-segment elevation acute myocardial infarction was mad…
