Double primary left ventricular and aortic valve papillary fibroelastoma.

Papillary fibroelastomas of the heart are relatively rare benign tumors and although they can be symptom free, symptoms such as cerebral ischemia and cardiac infarction can be lethal. It is important to diagnose this tumor using echocardiography, because lethal embolisms can be prevented by surgical resection. Recurrence of this tumor has not been reported and multiple tumors are rare. The present report is a case of double primary aortic valve fibroelastoma with aortic regurgitation diagnosed 4 years after surgery for a left ventricular fibroelastoma with mitral valvular disease.

Echocardiographic features of second degree atrioventricular block.

Echocardiographic studies demonstrated abnormalities of motion of the pulmonary valve, the aortic root and valve, the mitral and tricuspid valves, the left ventricle, and the left atrium in two patients with second-degree atrioventricular block. During Wenckebach 3:2 atrioventricular conduction, ventricular beats exhibited alternately long and short periods of systolic opening of the pulmonary and aortic valves and alternately large and small left ventricular stroke volumes. During 4:3 and 3:2 Wenckebach atrioventricular conduction, the left ventricular stroke volume was directly proportional to the preceding end-diastolic volume. During 2:1 atrioventricular conduction, the blocked atrial contractions may produce movements of the left atrial wall, thereby revealing the true atrial rate when the blocked P waves are obscured in the electrocardiogram by their superimposition on preceding T waves.

Yield of endomyocardial biopsy in patients with biventricular failure. Comparison of patients with normal vs reduced left ventricular ejection fraction.

Twenty five patients with biventricular failure underwent endomyocardial biopsy procedures. Twelve of these 25 patients had normal left ventricular ejection fraction. Endomyocardial biopsy sampling was useful in eight of 12 patients (67 percent) with biventricular failure and normal left ventricular ejection fraction. Biopsy specimens in five of these 12 patients demonstrated endocardial or infiltrative heart disease and excluded these diseases in three other patients with constrictive pericarditis. This study suggests that the clinical presentation of biventricular failure, combined with the noninvasive determination of a normal left ventricular ejection fraction, is helpful in selecting patients for endomyocardial biopsy study. Patients with biventricular failure and normal left ventricular ejection fractions have a high probability of having pericardial or infiltrative heart disease, conditions that often can be differentiated only by analysis of myocardial tissue. Hemodynamic assessment of patients without infiltrative processes further allows one to eliminate those patients with a high likelihood of having constrictive pericardial disease.

A case of arrhythmogenic right ventricular dysplasia with atrial flutter.

A 57-year-old male who had arrhythmogenic right ventricular dysplasia (ARVD) with recurrent atrial flutter (AF) is reported. The patient had more frequent episodes of AF than of ventricular arrhythmias. Magnetic resonance imaging, echocardiography and right ventriculography revealed dilatation of the right ventricle and endomyocardial biopsy specimens from the right ventricle showed findings which were compatible with ARVD. The left ventricular specimen, however, also revealed a loss of myocytes and interstitial fibroelastic changes. The present case demonstrates an overlap of post-inflammatory or primary endomyocardial fibroelastic changes with ARVD.

Aortic valve repair for papillary fibroelastoma.

We report the case of aortic valve-papillary fibroelastoma in a 66-year-old Belgian woman with a previous single episode of cerebral transient ischemic attack. Transthoracic two-dimensional echocardiography revealed a small mass adherent to the noncoronary cusp of the valve, which was confirmed by transesophageal echocardiography. Indication for surgery was performed because of a previous cerebral transient ischemic attack and for its potential risk of cerebral and coronary embolization. Surgical excision of the mass was performed with the need for glutaraldehyde-treated autologous pericardial patch repair of the aortic cusp. Intraoperative and postoperative transesophageal echocardiography both showed the valve to be competent. Postoperative recovery was uneventful. After a review of the literature, we conclude that, even if asymptomatic, and independent of their size, aortic valve papillary fibroelastomas justify surgical excision for their potential to systemic embolization. Moreover, we believe that a valve-sparing approach might be feasible with no recurrence after complete excision.
