Isolated Noncompaction of the Left Ventricular Myocardium: A Case Report and Literature Review

Incremental value of live/real time three-dimensional transthoracic echocardiography in the assessment of right ventricular masses

This case series demonstrates the incremental value of three-dimensional transthoracic echocardiography (3D TTE) over two-dimensional transthoracic echocardiography (2D TTE) in the assessment of 11 patients with right ventricular (RV) masses or mass-like lesions (three cases of RV thrombus, one myxoma, one fibroma, one lipoma, one chordoma, and one sarcoma and three cases of RV noncompaction, which are considered to be mass-like in nature). 3D TTE was of incremental value in the assessment of these masses in that 3D TTE has the capacity to section the mass and view it from multiple angles, giving the examiner a more comprehensive assessment of the mass. This was particularly helpful in the cases of thrombi, as the presence of echolucencies indicated clot lysis. In addition, certainty in the number of thrombi present was an advantage of 3D TTE. Also, sectioning of cardiac tumors allowed more confidence in narrowing the differential diagnosis of the etiology of the mass. In addition, 3D TTE allowed us to identify precise location of the attachments of the masses as well as to determine whether there were mobile components to the mass. Another noteworthy advantage of 3D TTE was that the volumes of the masses could be calculated. Additionally, the findings by 3D TTE correlated well with pathologic examination of RV tumors, and some of the masses measured larger by 3D TTE than by 2D TTE, which was also validated in one case by surgery. As in the case of RV fibroma, another advantage was that 3D TTE actually identified more masses than 2D TTE. RV noncompaction was also well studied, and the assessment with 3D TTE helped to give a more definitive diagnosis in these patients.

Scholarship opportunities for trainees and clinician educators: learning outcomes from a case report writing workshop

INTRODUCTION

Publishing a case report demonstrates scholarly productivity for trainees and clinician-educators.

AIM

To assess the learning outcomes from a case report writing workshop.

SETTING

Medical students, residents, fellows and clinician-educators attending a workshop.

PROGRAM DESCRIPTION

Case report writing workshop conducted nine times at different venues.

PROGRAM EVALUATION

Before and after each workshop, participants self-rated their perceived competence to write a case report, likelihood of submitting a case report to a meeting or for publication in the next 6-12 months, and perceived career benefit of writing a case report (on a five-point Likert scale). The 214 participants were from 3 countries and 27 states or provinces; most participants were trainees (64.5 %). Self-rated competence for writing a case report improved from a mean of 2.5 to 3.5 (a 0.99 increase; 95% CI, 0.88-1.12, p < 0.001). The perceived likelihood of submitting a case report, and the perceived career benefit of writing one, also showed statistically significant improvements (p = 0.002, p = 0.001; respectively). Nine of 98 participants published a case report 16-41 months after workshop completion.

DISCUSSION

The workshop increased participants' perception that they could present or publish a case report.

Biventricular noncompaction: a case report

Myocardial noncompaction is an extremely uncommon cardiomyopathy. It can present as an isolated cardiac malformation or in association with other congenital anomalies. The left ventricle is usually affected, but a biventricular involvement rarely occurs. A predominant right ventricular involvement has not been reported. Here, we report an 18-year-old woman with biventricular noncompaction that predominantly involves the right ventricle.
