Comparative analysis of early postoperative results of transcatheter aortic valve implantation and surgical aortic valve replacement with a biological prosthesis.

OBJECTIVE: . Aim: The choice of aortic valve stenosis correction method is determined by a number of clinical and technical parameters. The task was to compare early postoperative outcomes in patients after correction of aortic valve stenosis using TAVI and surgical aortic valve replacement with a biological prosthesis. PATIENTS AND METHODS: Materials and Methods: This retrospective study analyzed the medical records of adult patients (18 years of age and older) who had transcatheter aortic valve implantation or surgical aortic valve replacement with a biological prosthesis at the State Institution "Heart Institute of the Ministry of Health" in the period from 2018 to 2022. RESULTS: Results: In 47 (47.5%) cases, TAVI was performed and in 52 (52.5%) cases, SAVR with a biological prosthesis was performed. Patients who underwent TAVI were significantly older (p=0.002) and had a higher EuroSCORE II operative risk score (p<0.001). In patients with TAVI, larger diameter aortic valve prostheses were significantly more often used compared with the SAVR group with biological prosthesis (27.5±2.74 vs. 22.5±1.84, p<0.001). The early postoperative period in patients with TAVI was characterized by an 11.4% (p=0.046) and 15.4% (p=0.006). The length of stay in the ICU (p=0.024), as well as the duration of hospitalization in general (p=0.005), was also significantly lower in patients with TAVI compared with patients with biological prosthesis SAVR. CONCLUSION: Conclusions: Despite the higher surgical risk of surgery according to EuroSCORE II, TAVI was characterized by a lower incidence of postoperative complications, with shorter duration of stay in ICU and hospitalization in general in comparison with patients undergoing SAVR with a biological prosthesis.

Isolated giant aortic arch aneurysm repair in a 13-year-old girl: a case report.

BACKGROUND: Aortic arch aneurysm is a very rare condition in children. Surgery is the life saving procedure but it performing might be challenging due to the complex anatomy. CASE PRESENTATION: We describe a 13-year-old girl who was diagnosed to have an isolated giant aortic arch aneurysm. This girl was referred to our institution with persistent cough as a leading symptom, which started two months ago. Surgery was performed as combined approach: left-sided thoracotomy and midline sternotomy. The left subclavian artery was re-implanted via supraclavicular approach to the left common carotid artery end-to-side anastomosis. Aneurysm was excised after midline sternotomy and initiation of cardiopulmonary bypass under mild hypothermia. Histological evaluation of the wall of the aneurysm revealed no evidence of any specific changes. CONCLUSIONS: The using of the combined method was characterised by a good postoperative surgical results. Pediatricians should be aware of persistent cough in children as a symptom of mediastinal mass of different origin and identity.

FIRST EXPERIENCE WITH OCCLUTECH PLD OCCLUDER TO CLOSE PARAVALVULAR LEAKS PROSTHETICS OF THE MITRAL VALVE. CASE REPORT.

This clinical case presents the results of using the Occlutech PLD occluder for transcatheter closure of a paravalvular leak (PVL) via a transapical approach in the remote period after mitral valve prosthetics. According to our results and to the literature, the procedure for closing the PVL of the mitral valve from a transapi¬cal approach using a special Occlutech PLD occluder is characterized by relative safety for patients, clinical effectiveness in terms of eliminating or reducing the degree of regurgitation and related symptoms.

Transcatheter aortic valve implantation in a patient with mitral valve replacement and tricuspid valve repair.

Aortic valve stenosis occurs in about 3% of people over 65. It is the most important heart valve disease in developed countries. Pathogenesis includes processes similar to those in atherosclerosis, including lipid accumulation, inflammation and calcification. A CASE REPORT: In this study, we describe the case transcatheter aortic valve implantation in a 73-year-old patient after mitral valve replacement and tricuspid valve repair 15 years ago. CONCLUSIONS: Transcatheter aortic valve implantation is an effective method of surgical treatment of elderly patients with aortic stenosis with a high risk of mortality in traditional surgical correction of defects. This type of treatment can be widely used in repeated interventions, where there is an adhesion process, technical complexity and a significant risk of complications. This method of treatment minimizes side effects and shortens the patient's rehabilitation period.
