  • Aortic valve infective endocarditis due to Streptococcus pyogenes : A case report. [Case Reports]
    IDCases. 2023; 31:e01697.Primera G, Hogan K, … Gallagher M
  • Group A Streptococcus is a common cause of pharyngitis, scarlet fever, glomerulonephritis, and various skin infections. However, there have only been a few reports of Group A Streptococcus (GAS) associated with infective endocarditis. We present a case of a 31-year-old male who presented to the hospital with a few days of weakness and myalgias after recently receiving treatment with azithromycin …
  • Infective Endocarditis as a Complication of Crohn's Disease on Immunotherapy. [Case Reports]
    Cureus. 2022 Dec; 14(12):e32847.Singh A, Ejaz A, … Singh D
  • A patient with a history of Crohn's disease on infliximab presented to the hospital with sepsis and a new heart murmur. He was found to have native aortic valve infective endocarditis from a rare species of group D Streptococcusin his blood. The patient was also noted to be in an acute flare of Crohn's disease. The hospital course was complicated by florid heart failure from acute aortic insuffic…
  • Matched comparison between external aortic root support and valve-sparing root replacement. [Journal Article]
    Heart. 2023 Jan 17 [Online ahead of print]Van Hoof L, Lamberigts M, … Aortic Valve Repair Research Network Investigators from the Heart Valve Society
  • CONCLUSIONS: VSRR and PEARS offer favourable mid-term survival, freedom from reintervention and preservation of valve function. Both treatments deserve their place in the surgical repertoire, depending on a patient's disease stage. This study is limited by its retrospective nature and different follow-ups in both cohorts.
  • Mitral Valve Replacement for Mitral Stenosis Secondary to Massive Mitral Annular Calcium. [Journal Article]
    Am J Cardiol. 2023 Feb 15; 189:131-136.Jeong M, Roberts WC
  • Mitral annular calcium (MAC) may produce mitral stenosis (MS) if its quantity is massive. We define massive MAC as the presence of a huge quantity of calcium underlying the posterior mitral leaflet and extending across all or nearly all of the ventricular aspect of the anterior mitral leaflet. This report was prompted to emphasize the hazards of performing mitral valve replacement in patients wit…
  • Ascending Aorta Sacular Aneurysm. [Case Reports]
    Port J Card Thorac Vasc Surg. 2023 Jan 14; 29(4):71.Carvalho Guerra N, Velho T, … Nobre Â
  • . A 83 year old woman with history of arterial hypertension, hypothyroidism, obesity, chronic renal insufficiency and incipient dementia was transferred to our hospital after complaints of chest pain. Investigation revealed a sacular ascending aortic aneurysm with the aneurysmal sac adjacent to the sternum. Due to her age, cognitive state and risk of sternal entry, she was refused for surgery. Sh…
  • Cerebrovascular pulsatility index is higher in chronic kidney disease. [Journal Article]
    Physiol Rep. 2023 Jan; 11(1):e15561.Oh ES, Freeberg KA, … Nowak KL
  • Patients with chronic kidney disease (CKD) are more likely to die of cardiovascular diseases, including cerebrovascular disease, than to progress to end-stage kidney disease. Cerebrovascular dysfunction, characterized by reduced cerebrovascular reactivity, cerebral hypoperfusion, and increased pulsatile flow within the brain, precedes the onset of dementia and is linked to cognitive dysfunction. …
  • Disease- and sex-specific differences in patients with heart valve disease: a proteome study. [Journal Article]
    Life Sci Alliance. 2023 Mar; 6(3)Nordmeyer S, Kraus M, … Mertins P
  • Pressure overload in patients with aortic valve stenosis and volume overload in mitral valve regurgitation trigger specific forms of cardiac remodeling; however, little is known about similarities and differences in myocardial proteome regulation. We performed proteome profiling of 75 human left ventricular myocardial biopsies (aortic stenosis = 41, mitral regurgitation = 17, and controls = 17) u…
  • Intra-Caval Balloon Pump. [Journal Article]
    J Invasive Cardiol. 2023 Jan; 35(1):E57-E58.Araj FG, Hall EJ, … Koshy T
  • This clinical image vignette describes the inadvertent placement of a balloon pump in the vena cava during a "code blue" scenario, and the lessons to be learned from that experience. The hemodynamic benefits of intra-aortic balloon pump during experimental cardiac arrest include shorter circulation time and increases in end-tidal CO2 and coronary perfusion pressure. However, the hemodynamic effec…
  • Anatomy of the mitral valve relative to controversies concerning the so-called annular disjunction. [Review]
    Heart. 2022 Dec 30 [Online ahead of print]Anderson RH, Garbi M, … Nijveldt R
  • It is now accepted that the mitral valve functions on the basis of a complex made up of the annulus, the leaflets, the tendinous cords and the papillary muscles. So as to work properly, these components must combine together in harmonious fashion. Despite the features of the arrangement of each component having been the focus of anatomical investigation for centuries, controversies still exist in…
  • The Role of Echocardiography in Extracorporeal Membrane Oxygenation. [Review]
    Curr Cardiol Rep. 2023 Jan; 25(1):9-16.Hockstein MA, Singam NS, … Kenigsberg BB
  • Extracorporeal membrane oxygenation (ECMO) is increasingly used to temporarily support patients in severe circulatory and/or respiratory failure. Echocardiography is a core component of successful ECMO deployment. Herein, we review the role of echocardiography at different phases on extracorporeal support including candidate identification, cannulation, maintenance, complication vigilance, and de…
  • Ross Procedure Versus Mechanical Versus Bioprosthetic Aortic Valve Replacement: A Network Meta-Analysis. [Review]
    J Am Heart Assoc. 2023 Jan 03; 12(1):e8066.Yokoyama Y, Kuno T, … Fukuhara S
  • Background The Ross operation appears to restore normal survival in young and middle-aged adults with aortic valve disease. However, there are limited data comparing it with conventional aortic valve replacement. Herein, we compared outcomes of the Ross procedure with mechanical and bioprosthetic aortic valve replacement (M-AVR and B-AVR, respectively). Methods and Results MEDLINE and EMBASE were…
  • Delayed aortic regurgitation after TEVAR procedure: a case report. [Case Reports]
    J Cardiothorac Surg. 2022 Dec 23; 17(1):336.Park SJ, Lee S, … Hong YS
  • CONCLUSIONS: Our results demonstrate that when a catheter-related procedure is performed around the aortic valve, slight injury of the valve can cause aortic insufficiency even 3 years after surgery. Consequently, when performing a catheter-related procedure around the aortic valve, special attention is always required.
  • Postpartum Endocarditis and Left Main Embolization. [Case Reports]
    CJC Open. 2022 Dec; 4(12):1096-1099.Atefi N, Lodewyks C, … Ravandi A
  • Postpartum infective endocarditis is a rare disease, especially in people with no risk factors (ie, intravenous drug use), that can be followed by severe morbidity and mortality. Here, we report a case of postpartum infective endocarditis with an unusual acute coronary syndrome-like presentation in a patient with minimal risk factors. In addition to lesions on the aortic valve causing severe aort…
  • Lipomembranous fat necrosis: A distinctive and unique morphology (Review). [Review]
    Exp Ther Med. 2022 Dec; 24(6):759.Matsukuma S, Matsunaga A, … Ogata S
  • Lipomembranous fat necrosis (LFN) is an uncommon but distinct form of fat necrosis, which is characterized by eosinophilic, crenulated and/or serpiginous membranes. LFN exhibits macrocystic, microcystic and/or crushed features. LFN is routinely detectable on hematoxylin and eosin (H&E)-stained sections, and is present both in the acute phase and in the later or fibrous stage of necrotic fatty les…
