Abstract Background: Up to now, transcatheter closure of patent ductus arteriosus(PDA) without severe pulmonary artery hypertension (PAH) has been well established and accepted in clinical practice. However, in PDA patients with severe PAH, transcatheter closure still remains a challenge, regardless of the tremendous advancement in devices and techniques.Methods: We reviewed the records of PDA patients who underwent transcatheter device closure though single femoral venous approach between January 2005 and December 2018. Severe PAH was defined as systolic pulmonary artery pressure (SPAP) measured by a catheter >70mmHg, excluding irreversible severe PAH assessed by trial occlusion. Propensity score matching was used to assemble a cohort of patients with similar baseline characteristics. Results: A total of 29 patients were in severe PAH (SPAH) group after excluding 2 for failing to the trial occlusion, and 468 in non-severe PAH(non-SPAH) group. After matching, 25 patients were in SPAH group, and 39 in non-SPAH group, without any significant difference in baseline characteristics. The median follow-up periods were 57 and 44 months for groups, respectively. No significant difference was noted in the rates of cumulative adverse events in the 2 groups (p=0.208). No poor effects in left ventricular function and residual shunt evaluated by transthoracic echocardiography(TTE) in SPAH group were detected in the short- and long-term follow-up.Conclusion: In the patients with PDA associated with reversible severe PAH, compared to non-severe PAH, transcatheter closure through single venous approach has comparable adverse events rates and successful closure rate, with equivalent results of TTE examination at the short- and long-term follow-up.

Abstract Background and aim Data on NOAC discontinuation patterns in Turkey are lacking. We conducted a subgroup analysis in ASPECT-NOAC study to determine anticoagulant discontinuation pattern in AF patients with recently initiated NOAC therapy. Methods ASPECT-NOAC was a national, multicenter, 12-month observational study conducted in 34 outpatient cardiology clinics of state, university, private, and research hospitals covering all geographic regions of Turkey. Adult AF patients who were under NOAC therapy for less than four months were enrolled. Patients who discontinued using their NOACs were recorded at the end of 12 months. A comparative analysis of patients with discontinuation of medication was conducted. Results This study included 991 non-valvular AF patients. NOAC continuation data were available for 854 patients. During study follow-up, 74 patients (8.7%) discontinued their NOAC medication. Mean age of these patients was 67.1±11.3 years old and 38 patients (51.4%) were female. Most commonly seen comorbidities were hypertension (66.2%) and coronary heart disease (39.2%). 29 patients (39.2%) had permanent (chronic) AF, followed by 26 patients (35.1%) with paroxysmal AF. Major reason for NOAC discontinuation was stated as physician request (n=46, 62%). Following reasons were patient request (n=17, 23%), other (n=9, 12%), and bleeding (n=2, 3%). Patients with NOAC discontinuation had a shorter duration of AF (21.7±41.7 vs 26.2±53.7 months, p=0.017). There was no significant difference of educational levels between medication discontinuation subgroups (p=0.637). Other baseline characteristics and patient disease and treatment awareness levels were similar with the patients who continued their medication. Of 74 patients, two patients died during the study because of cardiac failure. Conclusion NOAC continuity rate over 12 months was found to be high. NOAC discontinuation rate were higher in the patients with shorter duration of AF. Further studies with long-term follow-up detailing discontinuation reasons are warranted.

Introduction: Substantial heterogeneity exists in the cardiorespiratory fitness (CRF) change response to short-term supervised exercise training and its long-term prognostic implication is not well understood. Here, we evaluated the association between the short-term training related changes in CRF and CRF levels 10 years later. Methods: STRRIDE trial participants that were originally randomized to exercise training for 8 months and participated in the 10-year follow up visit were included. CRF levels were measured at baseline, post-training (8 months), and 10-year follow-up as peak oxygen uptake (VO 2 , ml/kg/min) using the maximal treadmill test. Participants were stratified into low, moderate, and high CRF response (CRF-R) groups according to the training-regimen specific tertiles of CRF change from baseline to post-training. Adjusted linear regression models were used to determine the association between short-term change in CRF with training and CRF levels at 10-year follow-up. Results: The study included 80 participants (age = 52 years, 35% women). There was no significant difference in the baseline characteristics of the CRF-R groups. At 10-year follow-up, high CRF-R group had the lowest decline in CRF compared with moderate or low CRF-R groups (-0.005 vs. -2.6. vs. -3.6 ml/kg/min, p = 0.009, Figure). This was largely related to the differential age-related changes in peak oxygen pulse across the three groups (0.58 vs. -0.23 vs. -0.86 ml/beat, p = 0.02) with no difference in the peak heart rate change. In adjusted analysis, high CRF-R was significantly associated with higher CRF levels at follow-up independent of the exercise intervention and other baseline characteristics [High vs. Low (ref) CRF-R: Std β = 0.25; p = 0.004] Conclusion: CRF change in response to short-term training is a significant predictor of age-related CRF decline over long-term follow-up. Thus, training responsiveness may identify individuals at risk for exaggerated CRF decline with aging and associated incidence of cardiovascular diseases.

Objective This study aimed to show the long-term results in patients who underwent unidirectional valve patch repair of ventricular septal defect with pulmonary artery hypertension. Methods Thirty-five acyanotic patients aged 2 to 26 years (mean 9.3 years) with a large ventricular septal defect and elevated pulmonary vascular resistance (mean 9.5 Wood units) underwent surgery in Madani Heart Hospital. The medical records and clinical outcomes were reviewed from March 1998 to March 2017. Results Five patients died in the first postoperative week. In the long-term follow-up (mean 11 years), two patients were lost to follow-up. Pulmonary artery hypertension gradually decreased in 17 patients within 6–12 months with significant improvement in right ventricular end-diastolic diameter, New York Heart Association functional class, and tricuspid regurgitation. Eleven patients with persistent pulmonary artery hypertension were divided into tolerable and non-tolerable groups. Six patients in the tolerable group had satisfactory conditions compared to before the operation, and gained weight with improved functional class despite echocardiographic findings of persistent elevated pulmonary artery pressure. One had a full-term delivery by caesarean section in the fifth postoperative year. Five patients in the non-tolerable group gradually developed right heart failure and complications such as extremity edema, ascites, pleural effusions, and died after 10–30 months. Conclusion Although relatively high mortality occurred during long-term follow-up, surviving patients were in a better condition and functional class despite persistent pulmonary artery hypertension. Therefore, fear of persistent pulmonary artery hypertension should not prohibit surgery in this group of patients.

Cystine Stones

Introduction: Cystine stone development is relatively uncommon among patients with urolithiasis, and most studies have reported only on small sample sizes and short follow-up periods. We evaluated clinical courses and treatment outcomes of patients with cystine stones with long-term follow-up at our center. Methods: We retrospectively analyzed 22 patients diagnosed with cystine stones between January 1989 and May 2019. Results: The median follow-up was 160 (range 6–340) months, and the median patient age at diagnosis was 46 (range 12–82) years. All patients underwent surgical interventions at the first visit (4 extracorporeal shockwave lithotripsy, 5 ureteroscopy, and 13 percutaneous nephrolithotripsy). The median number of stone events and surgical interventions per year was 0.45 (range 0–2.6) and 0.19 (range 0–1.3) after initial surgical intervention. The median time to stone events and surgical intervention was 2 years and 3.25 years, respectively. There was a significant difference in time to stone events and second surgical intervention when patients were divided at 50 years of age at diagnosis (p = 0.02, 0.04, respectively). Conclusions: Only age at a diagnosis under 50 was significantly associated with recurrent stone events and intervention. Adequate follow-up and treatment are needed to manage patients with cystine stones safely.
