AI Article Synopsis

  • This study investigates the occurrence and impact of left-sided cardiac thrombi (blood clots) that are unexpectedly found during cardiac CT angiography (CCTA).
  • Out of 1,080 CCTAs reviewed, 4.53% showed incidental thrombi, with 16 in the left atrium and 33 in the left ventricle, leading to necessary anticoagulation treatment.
  • The findings indicate patients with these incidental thrombi faced a higher risk of embolic complications, including deaths, highlighting the importance of careful interpretation of CCTAs by physicians.

Article Abstract

Objective: Intracardiac thrombi are intermittently come across on cardiac computed tomography angiography (CCTA). This study aimed to examine the prevalence, outcome, and prognosis in patients with incidental found left-sided cardiac thrombi on CCTA.

Material And Methods: The Ethics Committee approved the present study of the Faculty of Medicine, Khon Kaen University, Khon Kaen, Thailand. A retrospective review of CCTA was performed for incidental left-sided cardiac thrombi.

Results: A total of 1080 CCTAs were enrolled with the prevalence of incidental left-sided cardiac thrombi is 4.53%. Of the 49 patients with CCTA incidental left-sided cardiac thrombi, 16 had left atrial thrombi, and 33 had left ventricular thrombi. All thrombi were undetermined before the CCTA, and their identification subsequently generated anticoagulation treatment. In 10 patients, embolic complications happened, 4 of which were fatal. Patients with incidental detected left-sided intracardiac thrombi seen by CCTA had more embolic event than patients who did not discover left-sided intracardiac thrombi by CCTA (HR = 8.07; 95% CI 1.48-44.06;  = 0.016).

Conclusions: Incidental left-sided cardiac thrombi on CCTA guided to management adjustments and seemed to present substantial mortality and morbidity in the present study. Physicians who interpret CCTA should ensure a dedicated effort not to disregard these prospective pitfalls.

We report the case of a four-month-old male infant diagnosed incidentally with bilateral congenital diaphragmatic hernias. Our patient was found to have chest asymmetry during an unrelated hospital visit and bilateral diaphragmatic defects were confirmed on cross-sectional imaging. Surgical repair of a right-sided Bochdalek hernia and a left-sided Morgagni hernia was performed with excellent outcomes.

"Situs inversus with levocardia" refers to the mirror-image lateral orientation of the abdominal organs with a normally oriented, left-sided heart. This anatomical anomaly arises from abnormalities in the biochemical signaling systems mediating embryological development. We present a case of situs inversus with levocardia incidentally discovered in a healthy 24-year-old male during workup following a motor vehicle collision.

The biliary system exhibits significant anatomical variations, which pose challenges for most surgeons during cholecystectomy. Among these variations, a true left-sided gallbladder (LSG) is an uncommon finding. In such cases, the gallbladder is located to the left of the round ligament.

Introduction: The coexistence of gallbladder (LSG) and adenomyomatosis (ADM) is extremely uncommon presenting a novel clinical dilemma that has not been previously documented. LSG refers to a anomaly where the gallbladder is situated to the left of the round ligament deviating from its usual position. This anomaly is rare, with reported occurrences ranging between 0.
