    Surgical Outcomes and Long-Term Follow-Up of Patients with Large Ventricular Septal Defects with Severe Pulmonary Arterial Hypertension: Single-Center Experience
    (2023) Orgun, Ali; Tokel, Kursad; Erdogan, Ilkay; Varan, Birgul; Ozkan, Murat; Aslamaci, Sait
    Purpose: In this retrospective study, pediatric patients who underwent surgery for large ventricular septal defect (VSD) with severe pulmonary arterial hypertension (PAH) were evaluated in detail in terms of clinical characteristics, and long-term results, and reinterpreted with the current surgical criteria.Materials and Methods: Twenty-four patients who underwent surgery for large VSD due to PAH between 1994 and 2005 were included in the study. The patients were divided into two groups according to their pulmonary vascular resistance index (PVRI) and compared (group 1 with PVRI <6 WU.m(2) and group 2 with PVRI >= 6 WU.m(2)). The patients with PVRI 6-8 WU.m(2) were accepted as being in the gray zone and were evaluated in detail.Results: Age at diagnosis ranged from 5 months to 17 years (median: 5 years). PVRI ranged between 3 and 18.4 WU.m(2) (median PVRI was 5 WU.m(2).) According to the PVRI, 13 patients were accepted as group 1, and 11 patients were accepted as group 2. mPAP, PVR/SVR, and last PAP values were found statistically significantly lower in group 1 than in group 2. The median postoperative follow-up time was 6 years (range, 1 month-18 years). PAH was seen in 15/24 (62.5%) patients. Severe PAH was observed in seven of these 15 patients and all were in group 2 (four had PVRI >= 8WU.m(2) and three had PVRI 6- 8 WU.m(2)).Conclusion: Patients with large VSD with severe PAH should be carefully evaluated before surgery to more accurately identify suitable candidates.

    Early and late outcomes of surgical repair of double-chambered right ventricle: a single-centre experience
    (2020) Surucu, Murat; Erdogan, Ilkay; Varan, Birgul; Ozkan, Murat; Tokel, N.Kursad; Aslamaci, Sait; 0000-0002-6759-1795; 32063236; AAF-3253-2021; AAJ-2305-2021
    Objective: Double-chambered right ventricle is characterised by division of the outlet portion of the right ventricle by hypertrophy of the septoparietal trabeculations into two parts. We aim to report our experiences regarding the presenting symptoms of double-chambered right ventricle, long-term prognosis, including the recurrence rate and incidence of arrhythmias after surgery. Methods: We retrospectively investigated 89 consecutive patients who were diagnosed to have double-chambered right ventricle and underwent a surgical intervention from 1995 to 2016. The data obtained by echocardiography, cardiac catheterisation, and surgical findings as well as post-operative follow-up, surgical approaches, post-operative morbidity, mortality, and cardiac events were evaluated. Results: Median age at the time of diagnosis was 2 months and mean age at the time of operation was 5.3 years. Concomitant cardiac anomalies were as follows: perimembranous ventricular septal defect (78 patients), atrial septal defect (9 patients), discrete subaortic membrane (32 patients), right aortic arch (3 patients), aortic valve prolapse and/or mild aortic regurgitation (14 patients), and left superior caval vein (2 patients). The mean follow-up period was 4.86 +/- 4.6 years. In these patients, mean systolic pressure gradient in the right ventricle by echocardiography before, immediately, and long-term after surgical intervention was 66.3, 11.8, and 10.4 mmHg, respectively. There were no deaths during the long-term follow-up period. Surgical reinterventions were performed for residual ventricular septal defect (2), residual pulmonary stenosis (1), and severe tricuspid insufficiency (1). Conclusion: The surgical outcomes and prognosis of double-chambered right ventricle are favourable, recurrence and fatal arrhythmias are unlikely in long-term follow-up.
