Abstract
Background: Wolff-Parkinson-White syndrome is a rare but well-known disease that predisposes a person to cardiac arrhythmias. But sometimes this syndrome is accompanied by heart failure in the affected person. Several causes have been proposed for this complication including recurrent or incessant tachyarrhythmias that are frequently found in symptomatic (especially children) Wolf-Parkinson-White syndrome patients causing heart dysfunction and dilation and dilated cardiomyopathy, and also pre-excitation-related dyssynchrony leading to progressive ventricular remodeling and dilation. In this report, a patient is introduced who has improved his heart failure by radio-frequency ablation of free wall type of this syndrome.
Case Presentation: A 35-year-old man who had a history of Wolff-Parkinson-White syndrome from 8 years ago and suffered from dilatation and reduced left ventricular ejection fraction in recent years was presented with a pre-excited atrial fibrillation attack at the emergency department. The initial surface ECG showed positive delta wave in all precordial leads and negative QRS complexes in interior leads with QRS duration of about 200 ms. He had undergone electrophysiology study and ablation at the left postero-lateral accessory pathway. After ablation of accessory pathway within the months (from November 2022 until June 2023), left ventricular function was gradually improved and the symptoms of the patient's shortness of breath were also decreased.
Conclusion: The existence of heart failure in patients with Wolff-Parkinson-White syndrome can be due to various reasons including the presence of an accessory pathway and the dyssynchrony of intraventricular contraction which is caused by premature excitation of the connected part of the left ventricle by accessory atrioventricular pathway. Although in order to rule out the possibility of the incidental association of the accessory pathway with primary dilated cardiomyopathy and to investigate the segmental dyskinesia, it is necessary to perform diagnostic measures such as echocardiography and cardiac computerized tomography and magnetic resonance imaging, ablation of such accessory pathway not only controls arrhythmic attacks but also leads to the improvement of the left ventricular systolic function even in a middle age patient.

Abstract
Background: Choosing a specialty in medicine is an important decision for the individual. It is also important decision for the health system. This study aimed to investigate the factors affecting the interest of specialized assistants to continue studying in subspecialized fields.
Methods: This descriptive cross-sectional study investigated the factors affecting the interest of 261 specialized assistants to continue their studies in subspecialized fields from March 2021 to March 2022. All the specialized assistants of Kerman University of Medical Sciences (KMU), whose assistantship continued until the end of March 2022, were included in the study by census method. The data collection tool was a 4-part questionnaire. 1) demographic information including 13 questions (age, gender, marital status, city where the family lives, place of residence to complete the residency course, specialized field, level of education, grade point average, parents' education, parents' occupation and having first-degree relatives with subspecialized degrees), 2) the willingness or unwillingness to continue studying in subspecialized fields and the field of interest, 3) the reasons for the assistants' interest in continuing their education, included 14 questions, and 4) the reasons for the assistants' lack of interest in continuing their education, included 14 questions.
Results: The average age of the assistants was 31.53±3.90 years old. Most of the assistants were women (57.9%). 57.5 percent of the assistants were interested in continuing their studies in subspecialized fields. The most important reason for residents' interest in continuing their studies was "increasing practical-clinical knowledge" (80.1%). The most interest in continuing education was observed in internal assistants (17.33%). The assistant's age, specialist field and having first-degree relatives with a subspecialist degree had a significant relationship with the interest of the assistants to continue studying in subspecialist fields.
Conclusion: The results showed that a significant percentage of assistants were interested in continuing their studies in subspecialized fields. Age, the assistant's specialty and having first-degree relatives with a subspecialist degree had a significant effect on this interest.
