Intussusception is defined as telescoping of the proximal bowel (intussusceptum) into the lumen of the distal bowel, otherwise called the intussuscipiens. While it is one of the most common causes of intestinal obstruction in children between the ages of 3 months and 6 years, intussusception accounts for about 1% of such cases in adults. Intussusception is idiopathic in 8-20% of patients and most commonly occurs in the small intestines in adults. We describe the unique case of a colo-colonic intussusception in a 54-year-old female patient 1 week after a colonoscopy for suspected inflammatory bowel disease. The discussion focuses on the presentation and management options of intussusception.

Introduction: Prominent left ventricular trabeculations or left ventricular non-compaction (LVNC) is observed now more often with cardiac magnetic resonance imaging (MRI). The significance of LVNC in patients with preserved ejection fraction remains unknown however it may be a precursor to cardiomyopathy. Hypothesis: This study is aimed to evaluate the clinical outcome of patients with LVNC and preserved LV function compared to patients with normal myocardial anatomy and function. Methods: This is a retrospective analysis of patients referred for cardiac MRI between October 2012 and July 2017. Patients with hypertrophic cardiomyopathy, ischemic heart disease and infiltrative heart disease were excluded. Patients with prominent trabeculations and a noncompacted to compacted myocardial ratio ≥ 2.3 with a preserved left ventricular ejection fraction of ≥ 50% were included. The primary outcome is defined as cardiac hospitalizations resulting from chest pain, arrhythmias, syncope, and congestive heart failure. These patients were compared to patients who underwent cardiac MRI with preserved function and normal myocardial anatomy. Results: There were a total of 39 patients who met criteria of LVNC with preserved function by MRI. These were compared to 59 patients with preserved function and normal myocardial anatomy on MRI. There was no significant difference in demographics and LV size and function between the groups. In comparison with the control group, the LVNC group had a mean age of 44 ± 14 versus 42 ± 16, 62% female sex versus 59%, LV EF of 59 ± 5% versus 62 ± 6%, LV end diastolic volume of 148 ± 26 ml versus 146 ± 40 ml. There were a total of 7 cardiac hospitalizations, of which 5 occurred in patients with LVNC. LVNC was associated with a greater than 4-fold increased risk of events (HR4.6, 95%CI 1.0-21.8) (figure) Conclusions: In patients with preserved EF, LVNC anatomy is significantly associated with increased cardiac hospitalizations.
