Mycotic aneurysms of the aortic root. A pathologic study of 20 cases.

Twenty specimens of heart with mycotic aneurysms at the aortic root were studied. In ten cases, mycotic aneurysm followed infection of the aortic valve. In one case, it developed following infection of an aortic jet lesion, and in nine patients, the aneurysm was at the seat of a prosthetic aortic valve. In seven of the 11 cases with a natural aortic valve, the valve was either unicuspid or bicuspid. A retrospective evaluation of the data on the clinical records of the 20 patients revealed that infective endocarditis or noncardiac postoperative sepsis was present in 11. The most frequently isolated microorganism was Staphylococcus aureus. Conduction disturbances were found in six patients, all of them with involvement of the atrioventricular node by the aneurysm. Perforation into intracardiac cavities was found in four, two into the right ventricular infundibulum and one each into each atrium. Pericardial tamponade was caused by bleeding from the aneurysm in two cases, and myocardial infarction was a probable consequence of coronary arterial compression by the aneurysm in two cases. Mycotic aneurysms of the aortic root, in spite of their being partially or completely healed of active infection, carry a high risk of the complications enumerated. Among the 20 cases, cultures were positive in 11 and negative in nine. Staphylococcus aureus was cultured from five of the cases.

Accessory tissue of the tricuspid valve protruding into the left ventricle through a septal defect.

We report the pathologic findings in 13 cases with accessory tissue originating from the tricuspid valve and protruding into the left ventricular outflow tract through a ventricular septal defect (VSD). In eight cases the accessory tissue formed a pouch, the walls of which were similar to the tissue of the normal tricuspid valve. In five cases, papillarylike masses of young connective tissue formed the accessory tissue. The degree of left ventricular outflow tract obstruction was mild in five cases, intermediate in five, and severe in three. Adhesions to the rims of the VSD causing obstruction of the VSD were seen in ten cases. Associated anomalies were present in all cases. The most frequent associated anomalies other than the tricuspid valvular anomalies and the VSDs were transposition of the great arteries and a variety of vascular anomalies.

Prenatally diagnosed blocked atrial premature beats.

A case of persistent severe bradycardia in labor, diagnosed as blocked atrial premature beats, is presented. Simultaneous recording of fetal heart rate (FHR) and fetal electrocardiogram (FECG) during labor established an accurate diagnosis of an innocent fetal sinus bradycardia and differentiated it from fetal distress. This method should be applied in all cases of persistent fetal dysrhythmia, in order to differentiate it from hypoxic distress, and thus enable the obstetrician to avoid unnecessary cesarean sections.

Congenital atrial flutter.

Two cases of congenital atrial flutter, one of which was documented electrocardiographically before birth, are reported. In both patients sinus rhythm was restored with digoxin treatment; in one patient the transition was preceded by various arrhythmias. No cardiac malformation was found in either case, and no materal disease occurred during pregnancy. Both mothers had received medication during pregnancy, but its role as a causative factor is questionable.
