BACKGROUND: Takotsubo cardiomyopathy (TTC) can be diagnosed in patients presenting with clinical features of acute coronary syndrome (ACS) by using Mayo clinic criteria. Multiple precipitators have been attributed to causing TTC. Rarely it has been reported to occur following an acute envenomation. AIM: This review describes the various patterns, mechanisms, and outcomes of envenomation induced TTC. METHODS: In this review, we included all studies on "TTC" and "envenomation "published in the various databases before June 2022...

Russell's viper (Daboia russelii) is a deadly venomous snake that causes most snakebite deaths in Sri Lanka. It is widely distributed all over the country, and it commonly causes venom-induced consumption coagulopathy and neuroparalysis. Cardiotoxic manifestations after Russell's viper bites are rare. We report a 60-year-old man diagnosed with ST-elevation myocardial infarction after a proved Russell's viper bite.

INTRODUCTION: Although transient deep and giant negative T waves (NTWs) may develop during myocardial injury (MI) in humans, no data exist on this repolarization abnormality in canine MI. Therefore, this study aimed to describe the occurrence of transient deep/giant NTWs in dogs with MI. ANIMALS, MATERIALS AND METHODS: Medical records were retrospectively searched to identify dogs with MI and transient deep/giant NTWs. Signalment, history, and selected diagnostic test results were reviewed...

Echocardiographic evaluation is a diagnostic tool for the in vivo diagnosis of heart diseases. Specific and unique anatomical characteristics of the ophidian heart such as the single ventricular cavity, a tubular sinus venosus opening into the right atrium, the presence of three arterial trunks and extreme mobility in the coelomic cavity during the cardiac cycle directly affect echocardiographic examination. Twenty-one awake, healthy ball pythons (Python regius) were analysed based on guidelines for performing echocardiographic examinations...

Cardiac injury is infrequently described as a complication of snake bite envenomation. We present the case of a 62-year-old male with shortness of breath, right lower extremity edema, and elevated cardiac troponin 6 days after a Northern Pacific rattlesnake bite.

In the Himalayan region, there is a prevalence of unknown bites (not much data except media) including snakes with high range of mortality among victims because hilly terrain leads to delay in transportation and delayed initiation of proper treatment due to lack of developed tertiary care centers. These bites can present from local hypersensitivity reactions to neurological, cardiological, respiratory, hematological, musculoskeletal, and renal manifestations. We highlight two cases that presented with delayed and varied manifestations, recovered but delayed with dedicated supportive care...

The smooth, powerful muscles of a newborn baby?s heart are pulsing normally, squeezing in and letting go rhythmically as a 3-mm-wide catheter-like tube snakes its way through, entering via an artery and being guided slowly by a surgeon. When it reaches its target?a protruding knot of malformed muscle tissue within a ventricle that has been partly blocking the valve?the tip of the precisely controlled tube whirs into action, with tiny scissor-like rotating blades gently grinding up the excess tissue as those pieces are sucked back into the device, leaving no floating particles that could lead to a blockage elsewhere...

Cardiac leaders need to put forth cogent, well-articulated, conceptually sound reasons for pursuing issues that they consider to be significant to the future of their service. Logic, rationality, and quantification of issues are "givens"--they are the price of admission that one pays to have an issue contested in the organizational arena. Understanding the larger sphere in which CV issues reside by contextualizing logic and rationality in terms of organizational culture, power, politics, group dynamics, and ego improves the chance that the cardiac agenda will receive thoughtful consideration and support by organizational decision-makers...

A comparative analysis of cardiotropic activity of toxins has been studied in experiments on isolated heart of the poisonous animals from different systematic groups living on the territory of the USSR: reptiles (the venom of cobra, Vipera lebetina, Ancistrodon blomhoffi), amphibian (the venom of Bufo, Bombina, salamander), arachnids (the venom of Apis, Scolopendra, scorpion). The specific cardiotropic activity of the scorpion and Bufo venom has been discovered. The mechanisms of the cardiostimulative activity of scorpion venom have been found to be due to the activation of cellular adrenoreactive structures, and the Bufo venom to the activation of the intracellular calcium...
