Objective. To analyze the peculiarities of surgical treatment of a mitral stenosis, complicated by massive thrombosis of left atrium. Маterials and methods. The group analyzed, operated in the Institute, consisted of 344 patients. Thrombosis of left atrium was considered a massive, when thrombotic masses have occupied no less than one third of its volume, not mentioning an auricle of atrium. Results. Hospital lethality after change of a mitral valve have constituted 4.2% and directly depended on from a degree of the left atrium thrombosis (р < 0.05). After open mitral comissurotomy hospital lethality was not observed, witnessing the expediency of the thrombosis matrix extraction. Conclusion. During the operation for a massive thrombosis of left atrium it is important to remove a maternal base of thrombotic bed and to eliminate the left atrium auricle, what lowers essentially the risk for lethality and thromboembolic complications on a hospital stage. Doing preoperative computed tomography of head and abdominal organs constitutes obligatory condition for exclusion of a hidden thromboembolism occurrence.

Abstract Background Transcatheter mitral valve replacement (TMVR) may be a valuable treatment option for mitral annular calcification and severe mitral stenosis (MS) in patients at high operative risk. Pre-procedural virtual and printed simulations may aid in procedure planning, device sizing, and mitigate complications such as valve embolization or left ventricular outflow tract (LVOT) obstruction. Case summary We describe a case of TMVR in which multi-detector computed tomography (MDCT) derived, three-dimensional virtual planning and a 3D-printed model of the patients’ left heart provided enhanced understanding of an individual patient’s unique anatomy to determine feasibility, device sizing, and risk stratification. This resulted in deployment of an adequately sized valve. Post-TMVR LVOT obstruction was treated with LVOT balloon dilatation and percutaneous transluminal septal myocardial ablation. Discussion Advanced MDCT-derived planning techniques introduce consistent 3D modeling and printing to enhance understanding of intracardiac anatomical relationships and test device implantation. Still, static measurements do not feature haemodynamic factors, tissue, or device characteristics and do not predict device host interaction. Transcatheter mitral valve replacement is feasible in MS when adequately pre-procedurally planned. Multi-detector computed tomography-derived, 3D, virtual and printed models contribute to adequate planning in terms of determining patient eligibility, procedure feasibility, and device sizing. However, static 3D modeling cannot completely eliminate the risk of peri-procedural complications.

Giant Left Atrium

A 52 year-old male patient of severe MS with mild MR with AF with a giant left atrium (LA size 70 mm) and history of CMC presented with symptoms. Giant left atrium is a condition characterized by huge enlargement of the left atrium with a diameter exceeding 65mm. It is most commonly associated with long standing rheumatic mitral valve disease. The patient underwent successful mitral valve replacement and removal of LA thrombus and discharged from hospital with adviceCardiovasc. j. 2016; 9(1): 73-74

Abstract Aims   The evaluation of sinus rhythm preservation after surgical treatment of atrial fibrillation by left-atrial RFA in patients with mitral valve prosthetics. Materials and methods  A prospective, randomized study was performed in the interregional clinical and diagnostic center of Kazan in 2011-2018 which were included 136 patients with mitral valve pathology and persistent AF. The average age of patients was 57 ± 5, the gender division was dominated by female patients  and made up 97 (58.4%). All patients underwent either mitral valve prosthesis with mechanical prosthesis Meding-2 which made up 96 (70.5%) or biological prosthesis Carpantier-Edwards which made up 40 (29.4%). Radiofrequency isolation of the left atrium and pulmonary veins was performed by standard procedure by Cox-IV which doesn’t include the right atrium tissue. Results and discussion: In the early post surgical period, recovery of sinus rhythm was observed in 111 (81.6%) patients. Cardiac Pacemaker Implantation was performed in 1 (0.73%) case.  The results of the study were assessed after surgical treatment in 22 ± 5 months, the sinus rhythm was preserved in 99 patients from the study group and made up 72.7%. Conclusion Radiofrequency ablation  the left atrium provides long-term preservation of sinus rhythm in the treatment of patients with atrial fibrillation and mitral valve pathology.

Objective. Studying possibilities of the triangular plasty of left atrium procedure, performed while prosthesis of a mitral valve. Materials and metods. Into the main group 137 patients, suffering isolated mitral failure, complicated by left atriomegaly (diameter of left atrium ≥ 6.0 cм), to whom surgical treatment was performed in Amosov National Institute of Cardiovascular Surgery from 01.10.2010 to 01.01.2019 yr, were included. In all the patients a prosthesis of a mitral valve, preserving native structures of a mitral valve with reduction of the left atrium cavity, using procedure of the left atrium triangular plasty, was performed. Into a control group were included 57 patients, in whom a mitral valve correction without a left atrium reduction was performed only for a mitral valve failure and a left-sided atriomegaly (diameter of left atrium was ≥ 6.0 cm). Results. Of 137 patients of the main group on the hospital stage 3 (2.2%) have died. Dynamics of echocardiographic indices of the left atrium diameter on different stages was following: (65.5 ± 3.8) mm preoperatively, (51.5 ± 2.1) mm postoperatively, (52.5 ± 2.2) mm in a remote follow-up period, in a remote follow-up period in (5.1 ± 0.4) years at average, thromboembolic complications (the transient disorders of the brain blood circulation) were noted in (1.6%) of 125 patients. Of 57 patients of a control group on the hospital stage 2 (3.5%) have died. Dynamics of echocardiographic indices, concerning diameter of the left atrium on various stages was following: (66.7 ± 2.7) mm preoperatively, (63.5 ± 2.3) mm postoperatively, (71.5 ± 2.4) mm in the remote follow-up period. In the remote follow-up period in (7.1 ± 0.4) years, thromboembolic complications were noted in 7 (14.6%) of 48 patients. Conclusion. The procedure of triangular plasty of left atrium constitutes an obligatory stage while performing correction of a mitral failure in presence of a left-sided atriomegaly (diameter of left atrium ≥ 6.0 cm). The procedure is miniinvasive and effective, leads to significant improvement of the left atrium morphometry and is accompanied by low risk of the complications occurrence and hospital mortality. The data accumulated and estimation of remote results of the procedure permits her to occupy a significant place among other methods of atrioplasty.

Cor Triatriatum Sinister

A 3-year-old, 4-kg, castrated male domestic shorthair cat presented with signs of progressive respiratory distress. Thoracic radiographs showed pulmonary edema and pleural effusion. Echocardiography revealed a perforate membrane immediately above the mitral valve that divided the left atrium into proximal and distal chambers. The left auricle was proximal to the dividing membrane and connected to the markedly enlarged proximal left atrial chamber, consistent with the diagnosis of supravalvular mitral stenosis (SMS). Position of the obstructing membrane relative to the left auricle distinguishes SMS from cor triatriatum sinister (CTS). In CTS, the left auricle is distal to the dividing membrane and connects to the distal left atrial chamber.

Permanent Atrial Fibrillation

Excess dilatation of the left atrium >60 mm is known in the literature as a gigantic atrium. This dilation is most commonly encountered in the mitral insufficiency of rheumatic etiology, but also in severe prolapses of the mitral valve, permanent atrial fibrillation, and at the leftright shunt with cardiac insufficiency. In this paper, we presented a case study of severe mitral stenosis with giant LA with LA thrombus in a 42 years old female patient. The patient underwent successful mitral valve replacement and removal of LA thrombus and discharged from the hospital with advice. Bangladesh Heart Journal 2018; 33(2) : 141-144
