Experimental papillary muscle infarction

The Journal of Thoracic and Cardiovascular Surgery, 1968
Summary The concept of papillary muscle dysfunction has been evaluated in dogs. The papillary muscle was infarcted without altering the other components of the mitral valve mechanism, and the animals were evaluated at varying intervals by auscultation, cardiac catheterization, cineangiography, and autopsy.

Effect of hypokinesia on contractile function of cardiac muscle [PDF]

Rats were subjected to hypokinesia for two months and the contractile function of isolated papillary muscle was studied. Hypokinesia reduced significantly the isotonic contraction rate which depended on the ATPase activity of the myofibrils; it also ...

Cardiogenic shock mortality according to Aetiology in a Mediterranean cohort: Results from the Shock‐CAT study

ESC Heart Failure, Volume 12, Issue 2, Page 1336-1345, April 2025.
Abstract Aims Mortality in cardiogenic shock (CS) remains elevated, with the potential for CS causes to impact prognosis and risk stratification. The aim was to investigate in‐hospital prognosis and mortality in CS patients according to aetiology. We also assessed the prognostic accuracy of CardShock and IABP‐SHOCK II scores.

Right Ventricular Variants and Pulmonary Embolism—Association or Coincidence?

Clinical Medicine Insights: Cardiology, 2010
It has been stated that the interior of the right ventricle is as unique to each individual as one’s fingerprint. This statement is backed by numerous publications which demonstrates considerable variation in the number, shape and configuration of ...

CardiLect: A combined cross‐species lectin histochemistry protocol for the automated analysis of cardiac remodelling

ESC Heart Failure, Volume 12, Issue 2, Page 1398-1415, April 2025.
Abstract Background Cardiac remodelling, a crucial aspect of heart failure, is commonly investigated in preclinical models by quantifying cardiomyocyte cross‐sectional area (CSA) and microvascular density (MVD) via histological methods, such as immunohistochemistry.

Deceptive Thyroid Pathologies: Anaplastic Thyroid Carcinoma Mimics and Clinical Implications

Head &Neck, EarlyView.
ABSTRACT Background Beyond follicular‐derived thyroid carcinomas, lymphomas, and metastatic disease, there are rare pathologies of the thyroid gland that represent a challenge. We report patients with unusual malignancies that mimic similar aggressive cancers. Methods Retrospective case series.

Case Report: Transthoracic echocardiographic diagnosis of agenesis of mitral chordae tendineae with papillary muscle fusion

Frontiers in Cardiovascular Medicine
The complete absence of mitral valve chordae tendineae together with fusion of the papillary muscles constitutes an exceedingly uncommon congenital anomaly, seldom encountered in clinical practice and prone to diagnostic oversight.

Comparative Use of Double Bipolar Forceps Versus Ultrasound Energy Device in Transoral Robotic Thyroidectomy

Head &Neck, EarlyView.
ABSTRACT Purpose Transoral robotic thyroidectomy (TORT) offers excellent cosmetic outcomes and safe access to the central neck without a cervical incision. Traditionally, ultrasonic energy devices have been used for dissection and hemostasis, though these instruments are limited by unilateral use, bulkiness, and greater thermal spread.

Macroscopic, Histological and Ultrastructural Features of the Tongue of the Anatolian Wild Boar (Sus scrofa libycus)

Microscopy Research and Technique, EarlyView.
Integrated macroscopic, histological, and ultrastructural analyses revealed five distinct lingual papillae types (filiform, fungiform, conical, foliate, and vallate) in the Anatolian wild boar (Sus scrofa libycus). Mechanical papillae showed marked structural specialization, while gustatory papillae exhibited region‐specific distribution of taste buds.
