“…In 17 hearts, there was marked atrial dilatation (both atria in 11, the right atrium only in 5 and the left atrium only in 1). None of the hearts showed an either primary or secondary tumor [8]. The SA and AV node were not sampled.…”

Myocardial sleeves of pulmonary veins and atrial fibrillation: a postmortem histopathological study of 100 subjects

Atrial fibrillation (AF) is triggered by ectopic beats originating from extensions of the left atrial myocardium over the pulmonary veins (PVs), so-called myocardial sleeves. A total of 100 hearts (393 PVs) obtained at autopsy were studied. Of these, 50 were from patients with chronic AF and 50 from controls in sinus rhythm. Out of a total of 393 PVs studied, a sleeve was present in 349 PVs (88.8%). The myocardial sleeves frequently harboured senile atrial amyloid and scarring. These two changes were evaluated semi-quantitatively (grade 0-3). Amyloidosis was found in 68% of all hearts and in 55% of all sleeves. It was more frequent in patients with AF (58.5%) than in those without (51.7%), however, without statistical significance (p values 0.948, 0.306, 0.166 and 1). Scarring was present in all 349 sleeves studied. It was significantly more severe in patients with AF (average grade 2.44) than in those without (average grade 2.00) (p values <0.001, <0.1, <0.05 and <0.01). In conclusion, amyloidosis and particularly scarring of the myocardial sleeves of the pulmonary veins, appear to be common in the elderly population as an arrhythmogenic substrate for AF.

“…Their reported incidence ranges between 8.4% and 14.7% of all primary neoplasms of the heart. [1][2][3] Until recently cardiac lipomas were most commonly occasional findings of postmortem heart examination, but currently the increasing application of modern imaging techniques leads to early detection of such tumors in alive individuals. Cardiac lipomas occur in patients of all ages, affecting both sexes equally.…”

“…Most lipomas rest on the epicardial surface in virtually any site on the atrial-ventricular surface. 3 Intracavitary or intramyocardial development has also been described in several cases. [3][4][5][6][7] The most common chambers affected are the left ventricle and the right atrium.…”

“…2 Even though most commonly arise from the pericardium, they may occur throughout the heart. [3][4][5][6] Most of these tumors are found incidentally because they do not provoke symptoms. We briefly describe a patient who was hospitalized for digitalis intoxication and was found to have a solitary lipoma located in the interatrial septum.…”

Lipoma of the Interatrial Septum in a Patient With Chronic Atrial Fibrillation

The authors report on a 70-year-old woman with chronic atrial fibrillation that was hospitalized for digitalis intoxication and incidentally was found to have an interatrial lipoma. The diagnosis was established by transesophageal echocardiography, computed tomography (CT) scanning, and magnetic resonance imaging (MRI). Owing to the asymptomatic character and the benign nature of the tumor, a decision for conservative management was made.
