Hereditary cardiomyopathies include a diverse spectrum of myocardial disorders characterized by mechanical and electrical abnormalities, among which hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM) are distinguished. This paper dives into the genetic foundations of these conditions, with a focus on mutations in genes encoding sarcomere proteins, thin filament proteins, and calcium homeostasis regulators. The familial aggregation of cardiomyopathies underscores the substantial genetic component, with autosomal dominant inheritance patterns predominant in some cases. Genetic testing and counseling emerge as pivotal tools for early diagnosis, risk assessment, and the formulation of personalized treatment strategies. The integration of genetic insights into clinical management holds promise for improving patient outcomes and reducing disease burden. Further analysis of the molecular mechanisms underlying hereditary cardiomyopathies is critical for identifying novel therapeutic targets and advancing precision medicine approaches. By comprehensively exploring the genetic underpinnings of cardiomyopathies, this paper contributes to our understanding of these complex diseases and highlights the potential for innovative interventions to enhance patient care in the field of cardiovascular medicine.

Atrial fibrillation is the most commonly experienced type of cardiac arrhythmia and is the most associated with substantial clinical occurrences and expenses. This arrhythmia often occurs in its "silent" asymptomatic form, revealed only after complications such as a stroke or congestive heart failure have transpired. New smart devices confer effective advantages in the detection of this heart arrhythmia, of which photoplethysmography-based smart devices have shown great potential, according to previous research. However, the solution becomes a problem as widespread use and high availability of various applications and smart devices may lead to substantial amounts of false and misleading recordings and information, causing unnecessary anxiety regarding arrhythmic occurrences diagnosed by the devices but not professionally confirmed. Thus, with most of the devices being photoplethysmography based for detection of atrial fibrillation, it is important to research devices studied up to this point to find the best smart device to detect the aforementioned arrhythmias.

Postural orthostatic tachycardia syndrome (POTS) is a chronic, debilitating condition characterized by heterogeneous symptoms, such as lightheadedness, palpitations, pre-syncope, syncope, and weakness or heaviness, especially of the legs. It is frequently associated with hypermobile joints or conditions such as chronic fatigue syndrome, chronic abdominal pain, migraine headache, and diabetes mellitus. Described is a case of POTS, which though it is not rare, is rarely diagnosed. It can be diagnosed quickly with simple methods.

:- The most commonly experienced cardiac arrhythmia and the most associated with significant clinical occurrences and expenses is Atrial fibrillation (AF) . Predominantly Due to advances in diagnosis methods, AF has been reported a greater and increasing frequency. By 2030, 14 – 17 million AF cases are anticipated in the European Union, with 120 000 – 215 000 newly diagnosed patients per year. Estimates suggest approximately 3% of adults aged 20 years or older are likely of contracting the condition. AF is independently associated with a two-fold a doubly increased risk of all-cause mortality in women and a 1.5-fold increase in men. The silent form of AF is incidentally diagnosed during routine physical examinations, pre-operative assessments, or population surveys. Unfortunately,, in certain cases, silent AF is revealed only after complications such as a stroke or congestive heart failure have transpired. New smart devices present impactful advantages in the detection of this cardiac arrhythmia. However, the widespread use of these devices, and the large number of free apps with varying degrees of certification, may lead to a great amount of misleading information causing anxiety about arrhythmic occurrences diagnosed by the devices but not professionally confirmed. The possibility of illegitimate or inaccurate results causing panic in the general population would merely convert a solution into a problem. Therefore, it is important to find the best smart device for detection of atrial fibrillation.

Objective – The aim of this article is to present a case of POTS, which was diagnosed quickly with Holter ECG and whose symptoms improved promptly and dramatically with non-pharmacological therapy. Case Presentation – A 15-year-old female patient mother was admitted because of unusual episodes of dizziness, syncope with spontaneous recovery and palpitations. Most of these symptoms occurred fairly frequently on standing. The Holter ECG was done with recommendation to perform some activities during recording, such as to stand for ten minutes in the presence of another person and to write symptoms. It was noticed on the Holter ECG that she had increase in heart rate more than 60 beats per minute during these ten minutes followed by symptoms. The patient was diagnosed with POTS and nonpharmacological therapy was advised which was successful. Conclusion – POTS is a disabling condition with heterogeneous and atypical symptoms which mostly affects the young females. Sometimes, a long period of time is necessary to diagnose POTS. Therefore, it is important to diagnose quickly and to start with appropriate therapy which is unique for every POTS patient. Delay in diagnosis and treatment can lead to further disability in patients affected by POTS and their poor quality of life.

This paper presents the medical journals published in Bosnia and Herzegovina (BIH) in the period from 1878 to 1945. The first medical journal in BIH may be deemed to be Jahrbuch des Bosnisch-Hercegowinischen Landesspittales in Sarajevo (The Yearbook of the National Hospital of Bosnia and Herzegovina in Sarajevo). In a special part of this journal, doctors from Austro-Hungary serving in Sarajevo wrote scholarly articles about their patients' various ailments. Up to 1945 seven more medical journals were published in BIH: Trezvenost - Organ Jugoslavenskog Saveza Trezvenosti (Temperance - the Journal of the Yugoslav Temperance Society), Zdravlje - Lekarske pouke o zdravlju i bolesti (Health, Medical lessons on Health and Disease), Glasnik Lekarske komore za Bosnu, Hercegovinu, Dalmaciju i Crnu Goru (The Journal of the Chamber of Physicians of Bosnia, Herzegovina, Dalmatia and Montenegro), Glasnik Lekarske komore Vrbaske banovine (Journal of the Chamber of Physicians of Vrbaska banovina, Glasnik Lekarske komore Drinske banovine (Journal of the Chamber of Physicians of Drinska banovina), Vjesnik Zavoda za suzbijanje endemijskog sifilisa u Bosni i Hercegovini (Journal of the Institute for Combatting Endemic Syphilis in Bosnia and Herzegovina) and Časopis za medicinu i biologiju (Journal for Medicine and Biology). CONCLUSION Medical journals published in BIH in the period from 1878 to 1945 were published in times marked by specific political and social circumstances in BIH, in the time when BIH was not independent, and was under the influence of the health culture of the ruling regimes. Most of the authors of the articles published in these journals were citizens of the occupying authorities, although the papers published were mainly the result of research undertaken in BIH.

Twiddler's syndrome is a rare complication after pacemaker implantation usually caused by patient manipulation with generator. We describe a case of 70-year-old female patient with pacemaker who was admitted to the neurological clinic with syncope and suspicion for neurological disease. After neurological diagnostic tests that were negative and consultation with a cardiologist, Twiddler's syndrome was diagnosed.

Goal: The aim of this study was to show whether the concomitant functional mitral regurgitation in patients undergoing aortic valve replacement improves after this surgical procedure and to identify preoperative echocardiographic parameters that may influence the lack of improvement in mitral regurgitation (MR) after aortic valve replacement (AVR). Material and methods: The study included 45 patients with severe aortic stenosis and concomitant moderate to severe (+2/+3)mitral regurgitation. Results: The results of our study indicated an improvement in the degree of mitral regurgitation in 24 patients. The most prominent parameters responsible for the lack of improvement of mitral regurgitation in our study were LVIDd, ERO, RVol, pulmonary artery systolic pressure and left atrial diameter. Identification of echocardiographic predictors may assist in selection of patients for whom more aggressive surgical treatment is advised. Conclusion: Concomitant moderate to severe functional MR indicates that MV should be repaired or replaced at the time of aortic valve surgery where at least two of indicated predicted preoperative echocardiographic parameters are present.

Total atrioventricular (AV) block is inconvenient and serious complication of open heart surgery. Permanent total AV block requires the implantation of permanent pacemaker in order to allow normal hemodynamics and patient’s survival. In infancy additional challenge is the surgical approach, the selection of electrodes and PM, as well as place of implantation. We are publishing case report of successful double-chamber DDD pacemaker implantation at an infant born with Fallot tetralogy and with low birth weight due to complete AV block after primary surgical correction of these congenital defects.
