Case of Dilated Cardiomyopathy in Combination with Left Atrial Myxoma and Left Atriomegaly (Rare Clinical Case)

Case description. A 41-year-old male patient F. was admitted to the Department ofSurgical Treatment of Ac-quired Heart Diseases of the National Amosov Institute of Cardiovascular Surgery of the National Academy of Medical Sciences of Ukraine with a diagnosis: Dilated cardiomyopathy. Mitral-tricuspid insufϐiciency. Left atrial myxoma. Left atriomegaly. Pulmonary hypertension. The patient was operated with heart failure symptoms of NYHA functional class IV. After a week of medical preparation and additional examination,the patient was successfully operated on (remov-al of the left atrial myxoma, imposition of support rings on the left and right atrioventricular openings, paraanular plicacy of the left atrium). The postoperative period proceededwithout signiϐicant complications. On the 12th day after the operation, the patient was discharged in satisfactorycondition. In the remote period the patient died suddenly 3 years later. Conclusion. Taking into account the initial serious condition of a patient with advanced heart disease with a reduced left ventricular ejection fraction, left atriomegaly (7.8 cm), pulmonary hypertension (50 mm Hg) and comorbidities, complex reconstruction of the left heart in atriomegaly and ventriculomegaly leads to an improvement in the functional state of the myocardium and morphometric indicators of left atrium and left ventricular ejection fraction.

Comparison of modified total leaflet preservation, posterior leaflet preservation, and no leaflet preservation techniques in mitral valve replacement - a retrospective study

Background

Mitral valve replacement with the total leaflet preservation technique can yield good results; however, its development is limited by patient-valve mismatch. Therefore, we compared the efficacies of the modified total leaflet preservation technique, posterior leaflet preservation technique, and no leaflet preservation technique in mitral valve replacement.

Methods

Clinical records and echocardiographic data of 180 patients who underwent mitral valve replacement for rheumatic mitral valve disease between 2009 and 2017 were analysed retrospectively to summarise the operative experience and short-term (six months) results. The patients were divided into three groups: group A (n = 62), treated with the modified total leaflet preservation technique; group B (n = 80), treated with the posterior leaflet preservation technique; and group C (n = 38), treated with the no leaflet preservation technique.

Results

No significant difference in the preoperative clinical data was noted between the groups (p > 0.05). The clamp and recovery times of group A were longer (p < 0.05) and shorter (p < 0.05), respectively, than those of groups B and C. The postoperative left ventricular end-diastolic diameter, left ventricular end-systolic diameter, and left ventricular ejection fraction of group A were significantly better than those of groups B and C. The incidence of low cardiac output syndrome in group A was lower than that in group C (p < 0.05). There was no postoperative left ventricular posterior wall rupture or mechanical valve dysfunction in group A.

Conclusions

The short-term results of the modified total leaflet preservation technique were better than those of the other techniques. This technique is also suitable for patients with rheumatic mitral valve stenosis.
