Single center two years' experience of Ozaki procedure: Early follow-up.

The Ozaki Procedure is an innovative surgical technique aiming of aortic valve neocuspidization using glutaraldehyde-treated autologous pericardium was first developed by Ozaki et al in 2007. With this newly developed technique, valve replacement was achieved without using prosthetic material due to both aortic stenosis and aortic insufficiency. Between December 2020 and December 2022, a total of 59 patients were operated on with the Ozaki Procedure due to aortic valve pathologies in our center. We evaluated the pre- and postoperative as well as the first-month data of a total of 44 patients with isolated the Ozaki Procedure and compared their echocardiographic changes. Patients with isolated aortic valve pathology were included in the study. Fifteen patients who underwent simultaneous coronary artery bypass surgery and Ozaki Procedure were excluded from the analysis. In the first month after the operation, n:2 (%4.5) patients died. When the preoperative and postoperative 1st month echocardiographic data of the remaining patients were compared, it was found that the decrease in mean gradient, max gradient and peak velocity values in the aortic valve was statistically significant. This is due to the fact that reaching neo-valves has very similar hemodynamics to the native aortic valve. Aortic valve neocuspidization by Ozaki Procedure may be a viable alternative to both surgical aortic valve replacement (AVR) and transcatheter aortic valve implantation. Its popularity and application is increasing all over the world. Short and mid-term results are available in the literature. The short and mid-term results are good, and the long-term results are hopeful.

Tradition or Innovation in Sternal Dehiscence Repair: Robicsek Versus Titanium Plate.

Objectives: Sternotomy is still the most commonly used incision in cardiac surgery. Sternal complications are seen at a rate of 0.5% to 6.1%. Sternal dehiscence increases morbidity and mortality after cardiac surgery. To prevent dehiscence, the search for alternative sternum closure methods continues today. Titanium plates produced for this purpose can also be used in patients who are re-operated due to sternal dehiscence. In our study, we investigated the effects of titanium plate repair and robicsek repair on the results in patients who were reoperated due to sternal dehiscence. Methods: Thirty-four patients who underwent reoperation due to sternal detachment in our hospital between September 2013 and December 2020 and had no signs of infection in the pre-operative period were analyzed retrospectively. The patients were divided into three groups according to the surgical method applied. These groups are as follows: Group 1: The cases in which the robicsek method was used, Group 2: the cases in which the titanium plate method was used, and Group 3: The cases where the robicsek + titanium plate methods were used together. Results: There was no significant difference between the groups in terms of basic demographic characteristics and risk factors, leading to sternal dehiscence. There was no significant difference between the groups in terms of mortality and length of hospital stay. Considering the infection rates in the post-operative period, 20% and 21.4% post-operative infections were detected in Group 1 and Group 3, respectively, while 70% post-operative infection was observed in Group 2, which was repaired only with the Robicsek technique (p<0.05). Conclusion: As supported by most studies in the literature, titanium plate application provides a superior sternum stabilization compared to the classical wire cerclage method. When evaluated in terms of cost-effectiveness, titanium plate method can be applied in high-risk patients in terms of sternal dehiscence.

The oldest patient in literature of spontaneous true giant superficial temporal artery aneurysm.

Background: Superficial temporal artery (STA) aneurysms are very rare compared to vascular aneurysms of other regions. They are divided into two as true and pseudo. Pseudoaneurysm were much more common and often depend on an etiological factor but spontaneous true aneurysms are extremely uncommon and the etiologic causes are not clear yet. Case presentation: We present a 91-year-old female patient who consulted to us with swelling in front of the ear; there was no history of previous surgery or any trauma. The patient had a pulsatile mass in the preauricular region, which started 4 years ago and growed faster for the last 2 months. Conclusion: There was a mass consistent with a saccular type aneurysm whose continuity was observed with the temporal artery in imaging studies. The mass was excised under general anesthesia. The patient whose pathological examination was a true STA aneurysm was discussed in the light of the literature.

The fifth redo operation for mitral paravalvular leakage and free-floating closure device extraction: A case report.

Paravalvular leakage (PVL) is a serious complication of prosthetic valve surgery. Surgical and transcatheter methods can be used for treatment. It is rare for closure devices to detach and free float in cardiac chambers. Transcatheter methods can be reused, but surgical treatment is more appropriate if this reuse is due to an increase in PVL. Here, we present a successfully operated case with a closure device freely passing through the PVL from the ventricle to the atrium, after four surgical valve replacements and two transcatheter device closures, owing to infective endocarditis.

Combined mitral valve replacement and ravitch procedures in a patient with previous pneumonectomy: case report and review of the literature

Abstract Introduction: Significant anatomical and functional changes occur following pneumonectomy. Mediastinal structures displace toward the side of the resected lung, pulmonary reserve is reduced. Owing to these changes, surgical access to heart and great vessels becomes challenging, and there is increased risk of postoperative pulmonary complications. Methods: We performed a mitral valve replacement combined with a Ravitch procedure in a young female with previous left pneumonectomy and pectus excavatum. Results: She was discharged on postoperative day 9 and remains symptom-free 3 months after surgery. Conclusion: Thorough preoperative evaluation and intensive respiratory physiotherapy are essential before performing cardiac operations on patients with previous pneumonectomy.
