    An Experimental Case-Based Role Model Study of Mitral NeoChord Implantation with New Tools via Transapical Approach
    (2023) Doganozu, Ersin; Doganozu, Ayse Ceren; Beyazpinar, Deniz Sarp; Sezgin, Atilla; Muderrisoglu, Ibrahim Haldun; Aydinalp, Alp
    Increasing fragility with the aging population compels less invasive procedures. Even if cardiac surgeries are getting minimally invasive with new techniques and technological development in the fi eld, many valve surgery candidates suffer from being qualifi ed as inoperable due to fragility, unstable circulatory system, and to be post-myocardial infarction and their life is in danger every day that they are not operated. The main purpose of this case-based role model study is to invent a new technique for implanting a transapical mitral valve NeoChord implantation with new tools.

    (2022) Yesiler, Fatma Irem; Akmatov, Nursultan; Nurumbetova, Oktom; Beyazpinar, Deniz Sarp; Sahinturk, Helin; Gedik, Ender; Zeyneloglu, Pinar; 0000-0003-0159-4771; 36540477; AAJ-1419-2021
    Objective: Open heart surgery (OHS) is frequently performed on elderly patients. We aimed to investigate the risk factors associated with prolonged intensive care unit (ICU) stay in elderly patients undergoing open heart surgery. Materials and Methods: Medical records of all patients > 75 years who underwent OHS (coronary artery bypass grafting (CABG) and/or heart valve surgery) between June 1, 2013, and December 31, 2020, were retrospectively analyzed. Those staying in the ICU longer than five days were determined as prolonged ICU stay. Patients were divided into two groups, according to ICU stay <5 days and >5 days. Results: Out of the 198 patients included in the study, 130 (65.7%) were male. Seventy patients (35.4%) had prolonged ICU stay. The mean age was higher in patients within the prolonged ICU stay group when compared to the other group (79.9 +/- 3.5 years vs.78.1 +/- 2.7 years, p<0.001). The patients who used statins and angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARBs) in the preoperative period had a shorter ICU stay compared to those who did not (45% vs 31.4%, p=0.04; 57% vs 42.9%, p=0.03). The history of previous thoracic surgery (2.3% vs 10% p=0.03), emergency surgery (12.5% vs 24.5% p=0.04), and preoperative pacemaker usage (0.8% vs 7%, 1 p=0.01) were higher in the group of patients with prolonged ICU stay compared to the other group. Preoperative ejection fraction (EF)% (47.7 +/- 11.3 vs 51.1 +/- 8.8, p<0.001) and hemoglobin level (11.8 +/- 1.9 mg/dL vs 12.9 +/- 1.6, p<0.001) were lower in the group with prolonged ICU stay compared to the other group. Incidence of cardiac arrest (3.9% vs 15.7% p=0.006), presence of arrhythmia (16.4% vs 41.6%,p<0.001), frequency of pacemaker and intra-aortic balloon pump (IABP) usage (0 vs 10% p=0.002; 1.6% vs 8.6% p=0.02), and need for renal replacement therapy (3.1% vs 12.9%,p=0.02) were higher in the group with prolonged ICU stay compared to the other group. According to the logistic regression analysis; higher age (OR: 1.225, 95%CI 1.104-1.360, p<0.001), preoperative pacemaker usage (OR: 0.100, 95%CI 0.01-0.969, p<0.04), preoperative statin non-use (OR: 2.056, 95%CI 1.040-4.066, p<0.03) and preoperative low EF (OR: 0.947, 95%CI 0.915-0.981, p=0.002) were determined as independent risk factors for prolonged ICU stay. Conclusion: The incidence of prolonged ICU stay after OHS among patients >75 years was 35.4% in our cohort. Higher age, preoperative pacemaker usage, preoperative statin non-use, and low preoperative EF were associated with prolonged ICU stay.

    Pleuropericardial Window Prevents Pericardial Effusion Following Surgical Atrial Septal Defect Closure
    (2022) Ozkan, Murat; Beyazpinar, Deniz Sarp; Celik, Mehmet; Gunaydin, Cagri; 35943313
    Background: Pericardial effusion occurs frequently after surgical atrial septal defect closure. This complication carries the risk of development of cardiac tamponade and death. It is also the responsibility of the hospital for readmissions. Any measure in preventing the development of pericardial effusion is of paramount importance. In this report, our objective was to demonstrate the protective effect of creating a pleuropericardial window against the development of postsurgical pericardial effusion. Methods: Hospital records of all patients who underwent surgical atrial septal defect closure between January 2015 and December 2020 were reviewed. Patients were divided into 2 groups according to the creation of right/left pleuropericardial window during surgical ASD closure. There were 45 patients in group I in which a right pleuropericardial window was done, and 85 patients constituted group II in which pericardium was left intact. Results: None of the 45 patients in group I developed pericardial effusion, while 15 of 85 patients in group II developed pericardial effusion (P =.001). Ten patients developed more than mild pericardial effusion which required medical treatment, while 5 patients had to be re-hospitalized because of massive pericardial effusion and effusions were managed by percutaneous drainage. Conclusions: The creation of a right pleuropericardial window resulted in a safe postoperative recovery after surgical atrial septal defect closure in all patients with the development of no pericardial effusion. No adverse effect of the creation of a pleural communication was noted.

    Abdominal Problems in Children with Congenital Cardiovascular Abnormalities
    (2015) Guney, Lutfi Hakan; Araz, Coskun; Beyazpinar, Deniz Sarp; Arda, Irfan Serdar; Arslan, Esra Elif; Hicsonmez, Akgun; 26185717
    Background: Congenital cardiovascular abnormality is an important cause of morbidity and mortality in childhood. Both the type of congenital cardiovascular abnormality and cardiopulmonary bypass are responsible for gastrointestinal system problems. Aims: Intra-abdominal problems, such as paralytic ileus, necrotizing enterocolitis, and intestinal perforation, are common in patients who have been operated or who are being followed for congenital cardiovascular abnormalities. Besides the primary congenital cardiovascular abnormalities, ischemia secondary to cardiac catheterization or surgery contributes to the incidence of these problems. Study Design: Cross-sectional study. Methods: In this study, we aimed to screen the intra-abdominal problems seen in patients with congenital cardiovascular abnormalities who had undergone surgical or angiographical intervention(s). Patients with congenital cardiovascular abnormalities who had been treated medically or surgically between 2000 and 2014 were analyzed retrospectively in terms of intra-abdominal problems. The patients' demographic data, type of congenital cardiovascular abnormalities, the intervention applied (surgical, angiographic), the incidence of intra-abdominal problem(s), the interventions applied for the intra-abdominal problems, and the results were evaluated. Results: Fourteen (Group I) of the 76 patients with congenital cardiovascular abnormalities diagnosis were operated due to intra-abdominal problems, and 62 (Group II) were followed-up clinically for intra-abdominal problems. In Group I (10 boys and 4 girls), 11 patients were aged between 0 and 12 months, and three patients were older than 12 months. Group II included 52 patients aged between 0 and 12 months and 10 patients older than 12 months. Cardiovascular surgical interventions had been applied to six patients in Group I and 40 patients in Group II. The most frequent intra-abdominal problems were necrotizing enterocolitis and intestinal perforation in Group I, and paralytic ileus in Group II. Seven of the Group I patients and 22 of the Group II patients died. The patients who died in both groups had more than three congenital cardiovascular abnormalities in the same patient, and 80% of these patients had been operated for congenital cardiovascular abnormalities. Conclusion: The gastrointestinal system is involved in important complications experienced by patients with congenital cardiovascular abnormalities. The mortality rate was higher in operated patients due to gastrointestinal complications. Gastrointestinal complications are more frequent in patients with cyanotic anomalies. The presence of more than one congenital cardiovascular abnormality in a patient increased the mortality rate.
