We reviewed our clinical and echocardiographic experience in 70 consecutive patients with 73 cardiac myxomas, diagnosed over an 11 year period. There were 21 males and 49 females, ages ranged from 18 to 80 years. Only in 5.7% cases was the diagnosis of myxomas made clinically. 88.6% cases were initially diagnosed as having: mitral valve disease (70%), tricuspid valve disease (10%), ischemic heart disease (5.7%), cardiomyopathy (2.9%), and the remaining 5.7% were detected during family screening and follow-up. The mean duration of symptoms was 10.6 months. The commonest symptom was dyspnoea (80%), followed by constitutional symptoms (45.7%), embolization (30%), palpitation (25.7%), syncope (15.7%), pedal oedema (15.7%) and pain chest (12.9%). The sites of myxomas were as follows: left atrium, 58; right atrium, 9; and, biatrium, 3. All myxomas except 3 were attached to the interatrial septum. The site, size, shape, attachment, mobility, prolapse into ventricle, and surface characteristic of myxomas were accurately assessed by 2D-echocardiography and confirmed in all (65 of 70) who underwent surgery. When the morphological characteristic of myxomas were studied and correlated with clinical features large left atrial myxoma size was closely related with constitutional symptoms, congestive heart failure, with syncope and auscultatory findings suggestive of mitral valve disease, whereas smaller myxoma size and irregular surface were associated with embolization. Constitutional symptoms were only present in left atrial myxoma. Post-operative mean echocardiographic follow-up of 60 months showed no recurrence except in 2 with familial myxoma. We conclude that the majority of myxomas mimic many cardiovascular diseases and were detected in symptomatic patients, so a high index of clinical suspicion is important for its early and correct diagnosis. The size and appearance of the myxomas correlated with the presenting symptoms.

A seventy-year-old man was admitted at our hospital because of dyspnea. Echocardiogram and left ventriculogram showed an aneurysm formation of the membranous ventricular septum and small left-to-right shunt through ventricular septum defect and also severe mitral and tricuspid insufficiency. Operation was performed after medical therapy for congestive heart failure. During operation, mitral leaflets showed no organic lesions nor prolapse, but the annulus was dilated. The cause of mitral insufficiency, we thought, might be congenital, and the annulus dilatation was caused of mitral insufficiency, we thought, might be congenital, and the annulus dilatation was caused to produce tricuspid insufficiency secondary. The ventricular septal communication became small (diameter; 5 mm) and was associated with aneurysm formation of the remaining portion of the membranous septum. And the aneurysm, protruding to the septal leaflet of tricuspid valves, enhanced tricuspid insufficiency. It was reported by many authors that the aneurysm formation was related to spontaneous closure of ventricular septal defect. Patients with small ventricular septal defect, without any symptoms, must be followed intensively, or they might get cardiac complications, such as arrhythmia, right ventricular outflow obstruction, tricuspid insufficiency, and so on.

The natural history of uncomplicated mitral valve prolapse (MVP) is not clearly understood. To determine the site-related differences in regression and progression of MVP, 112 patients with idiopathic MVP were enrolled in this echocardiographic follow-up study. Cardiovascular complications, including dysarrhythmias (n = 3, 2.7%), overt congestive heart failure (n = 4, 3.6%), progression of mitral regurgitation over one grade (n = 28, 25.0%), newly confirmed chordal rupture (n = 1, 0.9%), and surgical repair (n = 2, 1.8%), were observed in these patients during a follow-up period of 1-13 years (mean, 4.0 +/- 2.8 years). Multivariate analysis and Kaplan-Meier analysis revealed that posterior leaflet prolapse and significant mitral regurgitation (grade >/=2) were considerable risks for cardiovascular complications. Regression of MVP was seen in 17 (18.7%) of the anterior prolapse patients; however, new prolapse was observed in 40 (35.7%) patients, mainly in posterior prolapse patients. These results suggest that site-related differences exist in uncomplicated MVP prognosis and that MVP in the posterior leaflet has a poor outcome compared to that in the anterior leaflet.

This is the case of a 27 years-old woman with signs and symptoms of severe untreatable congestive heart failure, anemia, gingival mucosa ulcers, photosensitivity and alopecia. The electrocardiographic, echocardiographic, angiographic and hemodynamic data oriented the diagnosis of restrictive cardiomyopathy, mitral insufficiency secondary to mitral prolapse and bi-atrial dilation. The histologic study of the endomyocardial biopsy, performed during catheterization, showed signs of endomyocardial fibrosis, and immunological analysis was compatible with systemic lupus erythematosus. As far as we know, this is the first case of endomyocardial fibrosis (Davies disease) associated with systemic lupus erythematosus published in the medical literature. The etiology of Davies disease remains unrevealed and its association with systemic lupus erythematosus suggest a probable autoimmune origin.

Mitral valve prolapse has previously been found to be associated with severe cardiovascular complications such as embolic insults, infectious endocarditis, and sudden cardiac death. However, at the same time, in particular after adopting M-mode and 2D echo for diagnosis, prevalence of the disease was found to be very high, especially in the young. The dilemma of a disease which is frequent and mostly asymptomatic, but in some cases has catastrophic complications, has been solved by implementation of more restrictive diagnostic criteria based on an appreciation of the spatial morphology of the mitral annulus. These criteria call for diagnosis exclusively based on long axis views and a prolapse of > 2 mm beyond a line connecting the leaflet insertion points. "Classic prolapse" additionally requires diastolic thickness of the mitral leaflets of at least 5 mm. Two recent studies, a population-based study of mitral valve prolapse prevalence, and a case-control study of juvenile stroke patients compared to a group of young patients without a history of stroke, shed further light on this disease. The authors found that prevalence of mitral valve prolapse in an average population is 2-3% (1.3% for classic prolapse), without age or sex preponderance; the rate of cerebrovascular insults, congestive heart failure, and atrial fibrillation of patients with prolapse does not exceed that of the rest of the population; however, mitral insufficiency is more frequent; young patients with a history of cerebrovascular insult do not have higher mitral valve prolapse rates than young patients without previous insult.

Ventricular septal defects (VSDs) are the most common congenital heart malformations seen in children. Because spontaneous closure occurs frequently, patients with small VSDs should be followed clinically with no limitations except endocarditis prophylaxis. Surgical closure is recommended for only small defects with significant associated lesions such as aortic regurgitation, aortic valve prolapse, right or left ventricular outflow obstruction, tricuspid regurgitation, left ventricle to right atrial shunt, or recurrent endocarditis. Enlarging left ventricular size or deteriorating left ventricular function would also be an indication for surgical repair. Moderate and large VSDs in infancy often require treatment of congestive heart failure with diuretics, digitalis, and afterload reduction. Surgical closure before 9 months of age is indicated for large VSDs and by 2 years of age for moderate shunts to prevent pulmonary vascular obstructive disease and the consequences of long-standing volume overload. Device closure of VSD is still in the investigational stage but holds promise for treatment of apical or multiple muscular VSDs.

A 21 year-old woman was admitted to our hospital because of chest and back pain after blunt chest trauma. On admission, consciousness was clear and a physical examination showed labored breathing. Her vital signs were stable, but her breathing gradually worsened, and artificial respiration was started. The chest roentgenogram and a subsequent chest computed tomographic scans revealed contusions, hemothorax of the left lung and multiple rib fractures. A transthoracic echocardiography (TTE) revealed normal left ventricular wall motion and mild mitral regurgitation (MR). TTE was carried out repeatedly, and revealed gradually progressive MR and prolapse of the posterior medial leaflet, although there was no congestive heart failure. After her general condition had recovered, surgery was performed. Intraoperative transesophageal echocardiography (TEE) revealed torn chordae at the posterior medial leaflet. The leaflet where the chorda was torn was cut and plicated, and posterior mitral annuloplasty was performed using a prosthetic ring. One month later following discharge, the MR had disappeared on TTE.

Different morphologic features of arrhythmogenic right ventricular cardiomyopathy (ARVC) have been described. However, it is still unclear whether they correspond to distinct forms of the same disease. A pathologic study was performed on a series of ARVC (15 from heart transplant and 12 from autopsy) from 2 Italian referral university hospitals. Based on both myocellular features and the nature of myocardial replacement, hearts were divided into 2 groups: infiltrative, with a lacelike pattern of transmural fatty infiltration and strands of normal residual cardiomyocytes (n = 11); and cardiomyopathic, with massive myocardial replacement by fibro fatty tissue and cardiomyopathic changes (such as hypertrophy and myofibril loss) of residual cardiomyocytes (n = 16). Hearts from the infiltrative group were mostly obtained at autopsy of patients who died suddenly. Fatty substitution was limited almost exclusively to the right ventricle. Mitral valve dysplasia (prolapse or cleft) was frequently present. Hearts from the cardiomyopathic group came mainly from heart transplants for congestive heart failure. Fibro fatty replacement was more extensive, usually biventricular. Active myocarditis and features suggestive of myocardial transdifferentiation were also observed. Despite these differences in clinical outcome and morphologic features, patients from the 2 groups showed similar mean age, sex distribution, occurrence of threatening ventricular arrhythmias, and prevalence of family history of sudden death, arrhythmias, or cardiomyopathy. Infiltrative and cardiomyopathic patterns represent different clinical and pathologic subsets of ARVC. Myocellular features are an important clue in the distinction between the two entities. The differentiation between the 2 patterns is feasible on endomyocardial biopsy and could give important prognostic information.

A 32-year-old man with Marfan syndrome was admitted to our hospital for detail examination of congestive heart failure. Doppler echocardiography showed severe mitral regurgitation due to prolapse of posterior mitral leaflet. Annuloaortic ectasia without aortic regurgitation was also detected by aortography. Considering the future operative need for aortic root and ascending aorta, we performed mitral valve replacement with a mechanical valve and preventive concomitant aortic root replacement with a composite valve graft. His postoperative course was uneventful. Optimal surgical treatment of mitral regurgitation and annuloaortic ectasia in Marfan syndrome is controversial because the underlying connective tissue defect theoretically might compromise repair durability. Several surgical options for mitral regurgitation and annuloaortic ectasia in Marfan syndrome are discussed.

We successfully treated a patient with accelerated aortic regurgitation due to localized aortic dissection with mitral regurgitation causing congestive heart failure. A 58-year-old female, who had suffered from aortic regurgitation for more than 10 years, had acute heart failure due to acceleration of aortic regurgitation. The surgical findings showed prolapse of the aortic valve due to localized dissection in the sinus of Valsalva. We performed a Bentall operation and a mitral valve replacement, with a favorable outcome. The postoperative course was uneventful.
