Background: In recent years, several actions have been made to shorten the chain of survival in out-of-hospital cardiac arrest (OHCA). These include placing defibrillators in public places, training first responders, and providing dispatcher-assisted CPR (DA-CPR). In this work, we aimed to evaluate the impact of these changes on patients’ outcomes, including achieving return of spontaneous circulation (ROSC), survival to discharge, and survival with favorable neurological function. Methods: We retrospectively retrieved data of all calls to the national emergency medical service in Ashdod city, Israel, of individuals who underwent OHCA at the age of 18 and older between the years 2018 and 2021. Data was collected on prehospital and hospital interventions. The association between pre-hospital and hospital interventions to ROSC, survival to discharge, and neurological outcomes was evaluated. Logistic regression was used for multivariable analysis. Results: During the years 2018–2021, there were 1253 OHCA cases in the city of Ashdod. ROSC was achieved in 207 cases (32%), survival to discharge was attained in 48 cases (7.4%), and survival with favorable neurological function was obtained in 26 cases (4%). Factors significantly associated with good prognosis were shockable rhythm, witnessed arrest, DA-CPR, use of AED, and treatment for STEMI. All patients that failed to achieve ROSC outside of the hospital setting had a poor prognosis. Conclusions: This study demonstrates the prognostic role of the initial rhythm and the use of AED in OHCA. Hospital management, including STEMI documentation and catheterization, was also an important prognostication factors. Additionally, when ROSC is not achieved in the field, hospital transfer should be considered.

Background Intravascular leiomyomatosis with intracardiac extension is a rare benign tumor seen exclusively in women, characterized by proliferation of uterine smooth muscle cells through the venous circulation into the inferior vena cava and the right heart chambers. Case summary A 47 years old women with history of previous hysterectomy due to myomatosis, presented with nausea, anorexia and bilateral lower limb swelling over the preceding two months. An outpatient abdominal ultrasound discovered a mass in the Inferior vena cava. Echocardiogram and Computed tomography demonstrated a large intravascular mass extending from the pelvis to the right heart chambers. The tumor was completely removed in a concomitant open-heart surgery and laparotomy. Post operative course was uncomplicated. A month later the patient was feeling well and in good clinical condition. The histological analysis consisted with intravascular leiomyomatosis. Discussion Intracardiac leiomyomatosis is a rare clinical condition which requires high index of suspicion. Multimodality imaging is usually required to establish the preoperative diagnosis, although the final diagnosis is achieved with tissue investigation. Complete surgical resection of the tumor is curative and associated with good long-term prognosis.
