Background
Permanent junctional reciprocating tachycardia (PJRT) is an infrequent form of atrioventricular re-entrant tachycardia. We report the clinical and electrophysiological properties of PJRT ...and outcomes of radiofrequency catheter ablation (RCA) in a large group of patients.
Methods
We included 62 patients with the diagnosis of PJRT. Radiofrequency catheter ablation was performed in all.
Results
Location of accessory pathway was right posteroseptal in 37 (59,7%) cases, right midseptal in 3 (4,8%), left posterior in 7 (11,3%), left lateral in 5 (8,1%), left posterolateral in 3 (4,8%), left anterolateral in 2 (3,2%), left posteroseptal in 2 (3,2%), middle cardiac vein in 2 (3,2%), and left coronary cusp in 1 (1,6%). Single procedure success rate was 90.3%. None of patients had recurrence during follow-up after repeat ablations. Overall long-term success rate was 98.4%. Left ventricular systolic function recovered in all patients with tachycardia-induced cardiomyopathy (TIC).
Conclusion
Retrograde decremental accessory pathways are mainly located in posteroseptal region. Radiofrequency catheter ablation is a safe and effective approach in patients with PJRT.
A ventricular pseudoaneurysm develops mainly after myocardial infarction complicated by a ventricular free wall rupture contained by localized pericardial adhesions. The risk of rupture in untreated ...pseudoaneurysms is approximately 30%-45%, and the mortality rate is 50%. Although there is no clear evidence of treatment in the literature, the main suggestion is to perform surgical treatment without delay. However, the age of the patients, additional comorbidities, and the accompanying severe mitral regurgitation and left ventricular systolic dysfunction considerably increase the mortality rate of the surgical procedure. The treatment of left ventricular pseudoaneurysm accompanied by severe mitral regurgitation has not been clarified in the literature, and patient-based individual approaches vary. In this case report, the clinical course of the three patients was explained with different treatment approaches, and we tried to create a resource for treatment approaches in light of the literature.
Optimal valve sizing provides improved results in transcatheter aortic valve replacement. Operators hesitate about the valve size when the annulus measurements fall into borderline area. Our purpose ...was to compare the results of borderline versus non-borderline annulus and to understand the impact of valve type and under or oversizing.
Data from 338 consecutive transcatheter aortic valve replacement procedures were analyzed. The study population was divided into 2 groups as 'borderline annulus' and 'non-borderline annulus.' Balloon expandable valves already have a grey zone definition. Similar to balloon expandable valves, annulus sizes that are within 15% above or below the upper or lower limit of a particular self-expandable valve size are defined as the 'borderline annulus' for self-expandable valves. The borderline annulus group was also divided into 2 subgroups according to the smaller or larger valve selection as 'undersizing' and 'oversizing.' Comparisons were made regarding the paravalvular leakage and residual transvalvular gradient.
Of these 338 patients, 102 (30.1%) had a borderline and 226 (69.9%) had a non-borderline annulus. Both the transvalvular gradient (17.81 ± 7.15 vs. 14.44 ± 6.27) and the frequency of paravalvular leakage (for mild, mild to moderate, and moderate, 40.2%, 11.8%, and 2.9% vs., 18.8%, 6.7%, and 0.4%, respectively) were significantly higher in the borderline annulus than the non-borderline annulus group (P <.001). There were no significant differences between the groups balloon expandable versus self-expandable valves and oversizing versus undersizing regarding the transvalvular gradient and paravalvular leakage in patients with borderline annulus (P >.05).
Regardless of the valve type and oversizing or undersizing, borderline annulus is related to significantly higher transvalvular gradient and paravalvular leakage when compared to the non-borderline annulus in transcatheter aortic valve replacement.
Secondary infection of the aorta is a sporadic and life-threatening disease. It is usually caused by infection and abscess in an adjacent structure. The most common mechanism for secondary aortic ...infection is a psoas abscess eroding the aortic wall, which rarely results in non-aneurysmal aortic rupture. Primary treatment is surgical aortic reconstruction, but the risk of emergency surgical treatment is high. Endovascular aortic stent-graft implantation can be lifesaving in this setting by stopping the bleeding. However, the crucial question of durability and late infections remains unanswered and warrants long-term antibiotic treatment and follow-up. In this report, we present a case of primary psoas abscess, which resulted in non-aneurysmal aortic rupture and its endovascular treatment.
Iatrogenic aortic dissection (IAD) during coronary interventions is a rare but fatal complication. There is not enough experience and trial on this subject. In this study, we report our IAD cases and ...their acute, short-term, and long-term results.
In this study, we screened 6,096 coronary angiographies performed in our center between February 2016 and February 2019. Ascending aortic dissection developed in 8 patients. A total of 7 patients had computed tomographic angiography images after the event and during the follow-up. We performed 1-month and 1-year follow-up examinations.
The incidence of IAD was 0.13%. The female sex ratio was as 63%. A total of 37% of the patients had presented with acute coronary syndrome. In 37% of the patients, dissection occured while support catheter use, but in the remaining patients, dissections developed owing to hydraulic pressure. Regardless of the Dunning staging, 7 patients were followed-up with medical treatment, and 1 patient with decreased coronary flow was referred to emergency coronary bypass surgery. Regression was in the first tomography in 4 patients and observed in the control tomography in the remaining patients with medical treatment. The in-hospital 1-month and 1-year mortality rates were 0%.
IAD is a fatal disease, and conservative follow-up is suggested due to lack of clear management recommendations. The findings in our study showed that medical treatment is the first choice for the hemodynamically stable patients when dissection is sealed by stenting; however, surgical treatment is required in patients with the decreased coronary flow.
Introduction: The most important way to reduce CVD-related mortality is to apply appropriate treatment according to the risk status of the patients. For this purpose, the SCORE risk model is used in ...Europe. In addition to these risk models, some anthropometric measurements are known to be associated with CVD risk and risk factors. Objectives: This study aimed to investigate the association of these anthropometric measurements, especially neck circumference (NC), with the SCORE risk chart. Methods: This was planned as a cross-sectional study. The study population were classified according to their SCORE risk values. The relationship of NC and other anthropometric measurements with the total cardiovascular risk indicated by the SCORE risk was investigated. Results: A total of 232 patients were included in the study. The patients participating in the study were analysed in four groups according to the SCORE ten-year total cardiovascular mortality risk. As a result, the NC was statistically significantly lower among the SCORE low and moderate risk group than all other SCORE risk groups (low-high and very high 36(3)–38(4) (IQR) p: 0.026, 36(3)–39(4) (IQR) p < 0.001, 36(3)–40(4) (IQR) p < 0.001), (moderate-high and very high 38(4) vs. 39(4) (IQR) p: 0.02, 38(4) vs. 40(4) (IQR) p < 0.001, 39(4) vs. 40(4) (IQR) p > 0.05). NC was found to have the strongest correlation with SCORE than the other anthropometric measurements. Conclusions: Neck circumference correlates strongly with the SCORE risk model which shows the ten-year cardiovascular mortality risk and can be used in clinical practice to predict CVD risk.
Abstract
We report a case of left atrial hematoma after ablation of left lateral concealed accessory pathway. A 46-year-old male patient experienced chest pain after radiofrequency ablation. ...Transthoracic echocardiography and computed tomography revealed the intramural mass consistent with hematoma in the left atrium. He was hemodynamically stable, and conservative approach was decided. Atrioventricular groove is a vulnerable part of left atrium, and ablation of left free wall accessory pathway may require targeting both atrial and ventricular surfaces of the mitral annulus. Avoidance of forceful catheter manipulation during the electrophysiological procedure is important for prevention of this complication. Optimal periprocedural anticoagulation might reduce the risk of procedure-related thromboembolic complications, but electrophysiologists should always pay attention to an intramural hematoma that may occur after radiofrequency catheter ablation.
