ABSTRACT Mitral valve perforation is most commonly due to infective endocarditis. Iatrogenic mitral valve perforation following aortic valve replacement has not been described previously. A 57 years male patient presented with complaints of progressive dyspnea on exertion and occasional palpitations. A preoperative diagnosis of severe aortic stenosis, sclerodegenerative aortic valve with normal left ventricle function was made on transthoracic echocardiography. A coronary angiogram showed single vessel disease involving proximal left anterior descending artery causing 80% stenosis. The patient was planned for aortic valve replacement (AVR) and CABG. Pre bypass TEE showed bicuspid aortic valve, thick, calcified, severe aortic stenosis and normal left ventricle systolic function. Mitral valve was morphologically normal with mild central mitral regurgitation jet. Patient underwent CABG and AVR under cardiopulmonary bypass support. Post CPB TEE examination showed 2 jets of mitral regurgitation in midesophageal aortic long-axis view (Fig. 1). There was a mild central MR jet and an additional mild MR jet from the body of anterior mitral leaflet. Transgastric short axis view showed turbulence in the region of A1 scallop of anterior mitral leaflet. We present the intraoperative TEE images of the patient with a discussion on the role of TEE in detection of mitral valve perforation and surgical decision making.

AbstractLow-flow low-gradient aortic stenosis (LFLG AS) with reduced left ventricle ejection fraction (LVEF) is still a diagnostic and therapeutic challenge. The aim of this paper is to review the latest evidences about the assessment of the valvular disease, usually difficult because of the low-flow status, and the therapeutic options. Special emphasis is given to the available diagnostic tools for the characterization of LFLG AS without functional reserve at stress echocardiography and to the factors that clinicians should evaluate to choose between surgical aortic valve repair, transcatheter aortic valve implantation, or medical therapy.

Echocardiographic Assessment

The previous reviews in this section of our Supplement1,2 have summarized the anatomic components of the ventriculo-arterial junctions, and then assessed the echocardiographic approach to the ventriculo-arterial junction or junctions as seen in the morphologically right ventricle. In this complementary review, we discuss the echocardiographic assessment of the comparable components found in the morphologically left ventricle, specifically the outflow tract and the arterial root. We will address the echocardiographic anatomy of the aortic valvar complex, and we will review the causes of congenital arterial valvar stenosis, using the aortic valve as our example. We will also review the various lesions that, in the outflow of the morphologically left ventricle, can produce subvalvar and supravalvar stenosis. We will then consider the salient features of the left ventricular outflow tract in patients with discordant ventriculo-arterial connections, and double outlet ventricles. To conclude the review, we will briefly address some rarer anomalies that involve the left ventricular outflow tract, showing how the transesophageal echocardiogram is used to assist the surgeon preparing for repair. The essence of the approach will be to consider the malformations as seen at valvar, subvalvar, or supravalvar levels,1 but we should not lose sight of the fact that aortic coarctation or interruption, hypoplasia of the left heart, and malformations of the mitral valve are all part of the spectrum of lesions associated with obstruction to the left ventricular outflow tract. These additional malformations, however, are beyond the scope of this review.

Objective. To research of possibilities of reconstruction of aorta`s ostium and ascending aorta during aortic valve replacement and simultaneous correction of mitral valve defects at patients with narrow aorta`s ostium. Materials and methods. The study group consisted of 46 patients with mitral-aortic heart diseases and combination with a narrow aortic mouth, who were operated on at the A Amosov National Institute of Cardiovascular surgery for the period from January 1, 2006 to January 1, 2020. All patients underwent reconstruction of the aortic root and ascending aorta according to the original method of posterior aortoplasty. There were 26 men (56.5%) and 20 women (43.5%). The age of patients ranged from 23 to 72 years (average - 58.4±7.3 years). 8 (17.4%) patients belonged to class III NYHA, 38 (82.6%) - to class IV. Results. Of the 46 operated patients at the hospital stage (30 days after surgery), 4 died (hospital mortality 8.7%). No fatalities were associated with surgical technique. The dynamics of echocardiographic parameters at the hospital stage was as follows: the systolic gradient on the aortic valve was before surgery 112.1 ± 15.2 mm Hg, on the aortic prosthesis at discharge - 23.2 ± 6.4 mm Hg; end-systolic index (ESI) of the left ventricle (ml/m²) - 59.1 ± 7.6 (before surgery) and 48.3 ± 5.9 (after surgery); left ventricle ejection fraction (EF) - 0.45 ± 0.04 (before surgery) and 0.53 ± 0.04 (after surgery). Conclusions. The proposed original technique of posterior aortoplasty allows to effectively expand the mouth of the aorta for further implantation of an artificial heart valve of larger diameter. The technique is quite safe. At the hospital stage there are no complications directly related to the technique of operations. At the early postoperative period, the morphometric parameters of the left ventricle (EF and ESI) improved. The technique can be successfully used for the correction of combined mitral-aortic valve defects.

The intraventricular blood flow changed by blood pump flow dynamics may correlate with thrombosis and ventricular suction. The flow velocity, distribution of streamlines, vorticity, and standard deviation of velocity inside a left ventricle failing to different extents throughout the cardiac cycle when supported by an axial blood pump were measured by particle image velocimetry (PIV) in this study. The results show slower and static flow velocities existed in the central region of the left ventricle near the mitral valve and aortic valve and that were not sensitive to left ventricular (LV) failure degree or LV pressure. Strong vorticity located near the inner LV wall around the LV apex and the blood pump inlet was not sensitive to LV failure degree or LV pressure. Higher standard deviation of the blood velocity at the blood pump inlet decreased with increasing LV failure degree, whereas the standard deviation of the velocity near the atrium increased with increasing intraventricular pressure. The experimental results demonstrated that the risk of thrombosis inside the failing left ventricle is not related to heart failure degree. The “washout” performance of the strong vorticity near the inner LV wall could reduce the thrombotic potential inside the left ventricle and was not related to heart failure degree. The vorticity near the aortic valve was sensitive to LV failure degree but not to LV pressure. We concluded that the risk of blood damage caused by adverse flow inside the left ventricle decreased with increasing LV pressure.

Objective: To evaluate the concentration of N terminal proBNP (NT-proBNP) and partially the serum uric acid in the severe condition of aortic valve dysfunction for assessment of left ventricle hypertrophy. Methods: The study was conducted in the signal transduction lab department of biochemistry Quaid-I-Azam University, Islamabad from September 2013 to February 2017. NT-proBNP and serum uric acid were measured in one hundred patients of aortic valve dysfunction. The patients were divided into three main groups: 1) Aortic stenosis, 2) Aortic regurgitation, and 3) Aortic stenosis with Aortic regurgitation. The results were compared between disease and controls groups. Results: High level of plasma NT-proBNP was detected in all the three disease groups of aortic valve (stenosis, p<0.001), (regurgitation, p<0.001) and (stenosis with regurgitation, p<0.001). In addition, non-significantly increased level of serum uric acid was also observed in left ventricle hypertrophy in all the three respective disease groups of aortic valve. Conclusion: Increased secretion of NT-proBNP during cardiac remodeling can be related to the severity of left ventricle hypertrophy due to aortic valve abnormality in all the disease groups of severe stenosis, severe regurgitation, and combine disease condition of severe stenosis and severe regurgitation. However, non-significant increase in uric acid concentration is also identified which may be due to one of the factors involved in left ventricle hypertrophy in all the three disease groups of aortic valve. The interaction of uric acid with NT-proBNP during cardiac remolding due to aortic valve dysfunction is still not clear. How to cite this:Jan MI, Khan RA, Sultan A, Ullah A, Ishtiaq A, Murtaza I.
