1/14. Multiple aneurysmal dysplasia of pulmonary valvular sinuses with congenital focal aplasia of the annulus.

    We report the case of a 22-year-old woman in whom a focal aplasia of the pulmonary valve annulus associated with a multiple aneurysmal compensatory dysplasia was found. This patient had been followed since the age of seven years for a congenital asymmetric hypertrophic cardiomyopathy. Cardiac Doppler analysis showed significant pulmonary valvular insufficiency. The patient underwent heart transplant surgery because of total and refractory cardiac insufficiency. Pathological examination of the explanted heart (at the European Homograft Bank) enabled us to describe this valvular malformation. To date, this anomaly has not been described in the literature. Whether it is a malformation discovered fortuitously, or whether it is responsible in part for some of the signs associated with congenital hypertrophic cardiomyopathy is unclear. However, its role might be disclosed by a rigorous investigation of the patient's family.

2/14. aneurysm of the left atrial appendage.

    A 43-year-old woman underwent excision of an aneurysm of the left atrial appendage, which had been causing cerebrovascular embolic episodes. We attribute the aneurysm to congenital dysplasia of the musculi pectinati in the left atrial appendage and of the bands of atrial muscle from which they arise. In appendix I, we draw attention to the morphologically similar arrangements of inner and outer bands that emanate from a common transverse interatrial band and yield morphologically similar medial, descending, and ascending palm-leaf arrangements of musculi pectinati. In addition, we observe that the strap-like arrangements of musculi in both atria connect the outer band with the para-annular segment of the inner band. In appendix II, we briefly review the literature concerning musculi pectinati and related bands.

3/14. prenatal diagnosis of ventricular aneurysm: a report of two cases and a review.

    Ventricular aneurysms have rarely been reported prenatally. Their prognosis is variable depending on factors such as early detection, their relative size in comparison to the ventricular cavity, growth on follow-up, and signs of cardiac failure. In view of the fact that it may be useful to report on additional cases in order to make available further information on aetiology, prognosis and neonatal management, we hereby report on two cases of ventricular aneurysm with good mid-term prognosis. One case of apical aneurysm of the left ventricle was associated with a muscular ventricular septal defect, the features of which are compatible with a fetal myocardial infarction and ventricular septal rupture in absence of coronary artery anomalies as demonstrated by catheterisation. Another case of sub-tricuspidal aneurysm of the right ventricle associated with mitral prolapse appears to be a component of diffuse connective dysplasia. Despite the early gestational age at diagnosis, the large size of the aneurysm and the associated defect, both the infants were asymptomatic in infancy prompting a conservative management.

4/14. Mitral annular aneurysm resulting from subaortic muscle resection.

    We present a case of mitral annular aneurysm as a very rare complication developing soon after the surgical relief of subaortic stenosis. The cause of the aneurysm was considered to be the disruption of aorto-mitral intervalvular fibrosa at the initial operation. The surgical repair was successfully performed without compromising either aortic or mitral valvular functions. The preoperative transesophageal echocardiography was useful in delineating the precise anatomic features of this rare complication.

5/14. False aneurysm of the mitral-aortic intervalvular fibrosa after uncomplicated aortic valve replacement.

    False aneurysms of the mitral-aortic intervalvular fibrosa are rare and usually complicate aortic valve endocarditis. We report a case of a false aneurysm of the mitral-aortic intervalvular fibrosa after recent bioprosthetic aortic valve replacement in the absence of endocarditis.

6/14. An unusual complication after aortic valve replacement.

    Pseudoaneurysm of the mitral-aortic intervalvular fibrosa, though rare, can occur after aortic valve replacement. We report an asymptomatic patient who developed this unusual complication and describe the use of transesophageal and 3-dimensional echocardiography to help confirm the diagnosis.

7/14. Isolated fibromuscular dysplasia of the coronary arteries with spontaneous dissection and myocardial infarction.

    fibromuscular dysplasia (FMD) is a segmental, nonatherosclerotic vascular disease of unknown etiology. Both the renal and extrarenal arterial FMD may have focally deficient or absent muscular media, and spontaneous dissection is a serious complication of this arterial wall abnormality. Although FMD may be found in virtually any small and medium-sized arteries, to our knowledge, FMD of the coronary arteries previously has not been documented convincingly in the literature. This article describes one such unusual occurrence of FMD in the coronary arteries with spontaneous dissection and myocardial infarction.

8/14. Accessory atrioventricular pathway in association with ventricular septal aneurysm.

    An unusual combination of ventricular pre-excitation, right ventricular dysplasia and a ventricular septal aneurysm is described in a 23-year-old woman. The presence of an accessory pathway was confirmed. The potential embryological mechanisms are discussed.

9/14. arrhythmogenic right ventricular dysplasia: detection by radionuclide ventriculography.

    A 35 year old female patient was referred for investigation and treatment of recurrent ventricular tachycardia. Cardiac examination and the echocardiogram were normal. Equilibrium radionuclide ventriculography demonstrated a reduction in right ventricular ejection fraction (rest and exercise) while left ventricular ejection fraction was normal. It is proposed that radionuclide ventriculography may be the noninvasive study of choice to screen patients for arrhythmogenic right ventricular dysplasia. The right ventricular response to exercise may provide additional evidence for right ventricular dysfunction based on relative changes compared to the left ventricle. The diagnosis of arrhythmogenic right ventricular dysplasia may be subsequently confirmed by right ventricular angiography or endomyocardial biopsy, both of which are techniques which may not be performed during routine cardiac catheterization in the absence of the radionuclide ventriculography findings to suggest right ventricular dysfunction.

10/14. Cardiovascular manifestations in the Larsen syndrome.

    The Larsen syndrome consists of a skeletal dysplasia with multiple joint dislocations and a characteristic facies. The basis of the abnormalities is felt to be a generalized mesenchymal disorder involving connective tissues. More than 80 cases have been reported in the literature with isolated reports of congenital cardiac septal defects and acquired abnormalities of the aorta and mitral valve. A case with marked aortic dilation and insufficiency as well as an aneurysm of the ductus arteriosus is presented. The aortic lesions are similar to those described in other connective tissue disorders, particularly the marfan syndrome. Previous reports of ductal aneurysms have not revealed an association with connective tissue disorders, but have described a significant morbidity. In summary, patients with the Larsen syndrome are likely to have cardiac lesions similar to those classically associated with the marfan syndrome; these patients deserve a careful investigation for cardiac anomalies. These aortic lesions may be as prognostically significant as cardiac lesions in the marfan syndrome.
