    The effects of iron replacement on functional capacity in patients with group 1 and group 4 pulmonary hypertension
    (2022-10-01) ATAŞ, HALİL; KOCAKAYA, DERYA; YILDIZELİ, BEDRETTİN; MUTLU, BÜLENT; Akaslan D., Aslanger E., ATAŞ H., Kanar B. G. , KOCAKAYA D., YILDIZELİ B., MUTLU B.
    Objective: Abnormal iron handling complicates pulmonary hypertension and causes functional limitation and poor outcomes. Although preliminary results in group 1 pulmonary hypertension patients support the use of iron replacement, whether this applies to other PH subgroups is not known.

    Effects of balloon pulmonary angioplasty procedure on electrocardiographic parameters in patients with chronic thromboembolic pulmonary hypertension
    (2023-03-01) KOL, AYHAN; KEPEZ, ALPER; ATAŞ, HALİL; MUTLU, BÜLENT; KOL A., KEPEZ A., Akaslan D., Kanar B., ATAŞ H., MUTLU B.
    Aim: The aim of the present study was to evaluate the value of electrocardiography (ECG) in predicting post-operative hemodynamic improvement in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA).Material and methods: A total of 32 patients were included in the study. During ECG analysis, parameters that have been suggested to be related to right ventricular hypertrophy and/or dilatation were evaluated. The sig-nificance of the change in each parameter obtained at the pre-BPA visit and at the scheduled control visit 6 months after BPA was tested. In addition to ECG analysis, data related to right heart catheterization (RHC) and echocardiography, B-type natriuretic peptide (BNP) levels and World Health Organization (WHO) functional classifications of all patients were also recorded. The relationship between the amount of possible change in ECG parameters and the amount of possible change in hemodynamic parameters was investigated.Results: The Daniel score, which has been suggested to have prognostic value in acute pulmonary embolism, decreased from 8.22 +/- 5.68 to 6.56 +/- 5.55 after the BPA procedure (p: 0.035). Among all parameters studied, only T wave height (V2 t) in V2 derivation changed significantly from-0.77 +/- 2.39 to 1.27 +/- 2.58 mm (p: 0.036). The amount of change in V2 T was found to significantly correlate with the amount of change in systolic right ventricular pressure, mean pulmonary artery pressure, pulmonary vascular resistance, and systemic vascular resistance.Conclusion: Postprocedural T wave changes in lead V2 might serve as a marker of hemodynamic improvement in patients with CTEPH who undergo BPA.

    Intra-aortic balloon occlusion for refractory cardiac arrest in a patient with anterior myocardial infarction
    (2022-12-01) YILDIRIM, ÇAĞAN; UYSALER, EREN; NİZAM, AHMET CEM; ATAŞ, HALİL; TİGEN, MUSTAFA KÜRŞAT; MUTLU, BÜLENT; Aslanger E., Akaslan D., Yıldırım Ç., Uysaler E., Nizam A. C., Jafarov E., ATAŞ H., TİGEN M. K., MUTLU B.
    Despite recent advances in its management, the outcome of cardiac arrest is often poor despite appropriate cardiopulmonary resuscitation. The arteriovenous perfusion gradient achieved dur ing cardiopulmonary resuscitation is associated with the successful return of spontaneous cir culation. Continuous balloon occlusion of the descending aorta is an experimental method that can occlude the \"unnecessary\" part of the circulation, thus diverting generated pressure and blood flow to the heart and brain. In this study, we present a case report of a patient unre sponsive to standard cardiopulmonary resuscitation, in whom constant intra-aortic balloon occlusion achieved a return of spontaneous circulation and successful survival.

    Bendopnea predicts right ventricular energy failure in patients with pulmonary hypertension
    (2023-10-01) ATAŞ, HALİL; MUTLU, BÜLENT; Akaslan D., Aslanger E., Basa C. İ., Öztürk R. K., ATAŞ H., MUTLU B.
    OBJECTIVE: The development of right ventricular failure has a significant adverse prognostic impact on the course of pulmonary hypertension. Right ventricular energy failure has been shown to double the mortality of pulmonary hypertension even after correction for many established risk predictors. We hypothesize that bendopnea may indicate right ventricular energy failure in patients with pulmonary hypertension. METHODS: We prospectively enrolled patients with pulmonary hypertension who were admitted to our pulmonary hypertension outpatient clinic between January 2021 and June 2021. Bendopnea was assessed by asking patients to bend forward and report any shortness of breath within 30 seconds. Routine physical examination, laboratory tests, echocardiography, and right heart catheterization parameters were collected. RESULTS: A total of 167 patients were enrolled into the study. Bendopnea and right ventricular energy failure was present in 79 (47.3%) and 43 (25.7%) patients, respectively. Bendopnea accurately predicted the presence of right ventricular energy failure (area under the curve, 0.667; 95% CI, 0.574-0.760; P < 0.001) and had a significantly superior diagnostic power compared with many other symptoms and signs. CONCLUSIONS: Our study shows that bendopnea predicts right ventricular energy failure in patients with pulmonary hypertension and can be added to our physical examination armamentarium as an easy, rapid, and noninvasive prognostic tool.
