Aortic valve regurgitation and ventricular septal defect diagnosed 5 years after penetrating cardiac injury.

Despite high mortality rates for penetrating heart injuries, developments in transport, diagnosis, and surgical interventions have increased survival rates. In some cases, life-threatening complications may be misdiagnosed or remain asymptomatic and lead to loss of life. Herein, we report a patient with aortic valve regurgitation because of noncoronary cusp perforation and ventricular septal defect that remained asymptomatic and diagnosed 5 years after a penetrating heart injury.

Vascular complications of the intra-aortic balloon pump in patients undergoing open heart surgery: 10 years' experience.

BACKGROUND: The most encountered complications with intra-aortic balloon pump (IABP) use are seen within the vascular system. The purpose of our study is to evaluate vascular complications of the sheathless IABP in patients undergoing open heart surgery. METHODS: Between January 2002 and December 2011, a total of 148 patients undergoing open heart surgery and needed IABP support were included in the study. All vascular complications related with IABP were recorded. RESULTS: Mean age of the patients was 64.4 ± 9.4 years. Total 104 (70.2%) were male and 44 (29.8%) were female. Total number of patients who had ischemic complications of the extremity was 13 (8.7%). The most used surgical treatment was embolectomy in five patients. Only one patient required an iliofemoral bypass. Above the knee amputation was performed in one patient. No balloon-related mortality occurred. CONCLUSION: Incidence of vascular complications in IABP counterpulsation is still a problem despite improvements in catheter design and techniques. The presence of peripheral arterial disease and diabetes mellitus is important risk factors for ischemic complications.

The effect of thoracic epidural analgesia on short-term outcome and mortality in geriatric patients undergoing open heart surgery.

BACKGROUND: In open-heart surgeries, many organ functions, particularly the respiratory system, are affected by post-operative pain, and so is mortality. Following open-heart surgery, geriatric patients have a higher risk of organ dysfunction and mortality. We aimed to compare the short-term outcomes and mortality of thoracic epidural analgesia (TEA) and intravenous (IV) analgesia in geri-atric patients undergoing open heart surgery. METHODS: This study included patients over the age of 65 who had open-heart surgery between 2010 and 2020. The patients were divided into two groups: Those who received TEA (Group E) and those who received IV paracetamol or tramadol or dexmedetomi-dine (Group I). The patients' post-operative sedation and analgesia requirements, mechanical ventilation (MV) duration, blood glucose levels, liver and kidney function tests, complications, intensive care and hospital stay lengths, and mortality rates were all compared. RESULTS: The study included a total of 548 patients, with 408 in Group E and 140 in Group I. As a result of the comparisons be-tween the groups, sedation requirement, analgesia requirement, MV duration, post-extubation facial mask oxygen requirement, non-invasive MV need, re-intubation requirement, and blood glucose level were found to be lower in Group E than in Group I. Moreover, periods spent in intensive care and lengths of hospital stay were found to be lower in Group E than Group I. There was no difference found between the two groups in terms of hospital mortality. CONCLUSION: In elderly patients undergoing open-heart surgery, TEA reduced the length of time in intensive care and hospital stays by improving the respiratory status and blood glucose regulation by supplying analgesia and sedation.

Extracorporeal membrane oxygenation experiences during COVID-19 pandemic, third wave with younger patients: A retrospective observational study.

OBJECTIVES: In this article, the results of severe coronavirus disease 2019 (COVID-19) cases followed with extracorporeal membrane oxygenation (ECMO) support in a 3-month period in the third wave when there were an increased number of cases of young patients in our intensive care unit (ICU) were presented. METHODS: The study was carried out with all COVID-19 patients who were given ECMO support in our tertiary referral hospital ICU after obtaining the consent of the Ministry of Health Scientific Research Platform and after the approval of the local ethics committee. Patient data were obtained retrospectively from intensive care bedside follow-up charts and computer records. The demographic and clinical characteristics of the patients were presented in average, median, and percentages. The data of the patients were evaluated and compared with the current literature. RESULTS: ECMO treatment was applied in seven patients who were followed up with severe COVID-19 pneumonia in the last 3 months. Venovenous extracorporeal membrane oxygenation (VV-ECMO) was applied to all patients. Five (71.5%) of seven patients were weaned from ECMO. Four (57.2%) of seven patients were discharged from the ICU and hospital in good health. While two of the patients had a cesarean section (C/S) before ECMO, one patient underwent C/S under ECMO. All three newborns were delivered via C/S and all were premature (C/S dates were 35 weeks, 32 weeks, and 27 weeks), and all were discharged from the hospital in good health. CONCLUSION: Our experience shows that ECMO in COVID-19 patients is a lifesaving treatment option that can be successfully applied in severe acute respiratory distress syndrome cases who do not respond to conventional treatments.

Impact of Surgeon Experience During Carotid Endarterectomy Operation and Effects on Perioperative Outcomes.

Objective: We evaluated the effect of surgeon experience on complication and mortality rates of carotid endarterectomy operation. Methods: Fifty-nine consecutive patients who underwent carotid endarterectomy between January 2013 and February 2016 were divided into two groups. Patients who had been operated by surgeons performing carotid endarterectomy for more than 10 years were allocated to group 1 (experienced surgeons; n=34). Group 2 (younger surgeons; n=25) consisted of patients operated by surgeons independently performing carotid endarterectomy for less than 2 years. Both groups were compared in respect of operative results and postoperative complications. Results: No intergroup difference was found for laterality of the lesion or concomitant coronary artery disease. In group 1, signs of local nerve damage (n=2; 5.9%) were detected, whereas in group 2 no evidence of local nerve damage was observed. Surgeons in group 1 used local and general anesthesia in 3 (8.8%) and 31 (91.2%) patients, respectively, while surgeons in group 2 preferred to use local and general anesthesia in 1 (4%) and 24 (96%) patients, respectively. Postoperative stroke was observed in group 1 (n=2; 5.9%) and group 2 (n=2; 5.8%). Conclusion: Younger surgeons perform carotid endarterectomy with similar techniques and have similar results compared to experienced surgeons. Younger surgeons rarely prefer using shunt during carotid endarterectomy. The experience and the skills gained by these surgeons during their training, under the supervision of experienced surgeons, will enable them to perform successful carotid endarterectomy operations independently after completion of their training period.

Bileaflet versus posterior-leaflet-only preservation in mitral valve replacement.

In the present study of mitral valve replacement, we investigated whether complete preservation of both leaflets (that is, the subvalvular apparatus) is superior to preservation of the posterior leaflet alone. Seventy patients who underwent mitral valve replacement in our clinic were divided into 2 groups: MVR-B (n=16), in whom both leaflets were preserved, and MVR-P (n=54), in whom only the posterior leaflet was preserved. The preoperative and postoperative clinical and echocardiographic findings were evaluated retrospectively. No signs of left ventricular outflow tract obstruction were observed in either group. In the MVR-B group, no decrease was observed in left ventricular ejection fraction during the postoperative period, whereas a significant reduction was observed in the MVR-P group (P=0.003). No differences were found between the 2 groups in their need for inotropic agents or intra-aortic balloon pump support, or in cross-clamp time, duration of intensive care unit or hospital stays, postoperative development of new atrial fibrillation, or mortality rates. Bileaflet preservation prevented the decrease in left ventricular ejection fraction that usually followed preservation of the posterior leaflet alone. However, posterior leaflet preservation alone yielded excellent results in terms of decreased left ventricular diameter. Bileaflet preservation should be the method of choice to prevent further decreases in ejection fraction and to avoid death in patients who present with substantially impaired left ventricular function.

Surgical pitfalls of minimally invasive direct coronary artery bypass procedure from the viewpoint of a surgeon in the learning curve.

INTRODUCTION: Minimally invasive direct coronary artery bypass grafting (MIDCAB) offers arterial revascularization of the left anterior descending (LAD) coronary artery especially in lesions unsuitable for percutaneous coronary interventions. By avoidance of sternotomy and cardiopulmonary bypass its invasiveness is less than that of conventional bypass surgery. AIM: We in this study discuss our surgical experience in the MIDCAB procedure. MATERIAL AND METHODS: Thirteen patients were operated on with the MIDCAB procedure. The inclusion criteria for MIDCAB were pure LAD disease totally occluded or severely stenotic. Patient demographics and preoperative and postoperative data were analyzed. RESULTS: Mean age of the patients was 60.0 ±8.6 years. Patients' preoperative and postoperative levels of cardiac CK-MB (creatine kinase MB) were not significantly different (p = 0.993). However, cardiac troponin I (p < 0.001), hemoglobin (p < 0.001) and hematocrit (p < 0.001) were significantly different. No perioperative myocardial infarctions or cerebrovascular accidents were seen. The patients were discharged at a mean day of 4.77 with oral antiaggregant therapy. No mortality was seen in the study population. CONCLUSIONS: Minimally invasive direct coronary artery bypass is associated with few perioperative complications. Minimally invasive direct coronary artery bypass in our experience is a very good option for single vessel LAD disease.

A good surgical option for ischemic mitral regurgitation in co-morbid patients: semicircular reduction annuloplasty.

BACKGROUND: Ring annuloplasty is the standard treatment of ischemic mitral regurgitation (MR), however, it has been associated with some drawbacks. It abolishes normal annular dynamics and freezes the posterior leaflet. In the present study, we evaluated Paneth suture annuloplasty in chronic ischemic MR and both early and mid-term outcomes of the technique on a selected population. METHODS: The study period was from June 2010 to June 2012. We operated on 21 patients who had the diagnosis of coronary artery disease and MR of grade 3 or 4. The patients had both a coronary artery bypass operation and the mitral semicircular reduction annuloplasty described by Paneth-Burr. The data on the patients were retrospectively collected. Patients were contacted by outpatient clinic controls for mid-term results. RESULTS: The male/female ratio was 10/11. The mean age of the patients was 71.0 ± 6.4 years. Preoperative and postoperative left ventricular ejection fraction was statistically similar (P = 0.973). Early postoperative MR grade (mean, 0.57 ± 0.51) was statistically lower than the preoperative MR grades (mean, 3.38 ± 0.50) (P < 0.001). There was no revision for excess bleeding. Two patients had prolonged hospitalization, one for sternal infection and the other for severe chronic obstructive pulmonary disease. No hospital or late postoperative deaths occurred. The mean late postoperative MR grade was 0.66 ± 0.97 degrees. One patient had progression of MR in the later follow-up, which was treated by mitral valve replacement. CONCLUSION: Semicircular reduction annuloplasty is an effective, inexpensive and easy surgical annuloplasty technique with low mortality and morbidity in severe symptomatic ischemic MR.
