Endovascular Repair of Ruptured Aortic Aneurysm: A Single-Center Experience

OBJECTIVE

Aortic rupture is a rare and catastrophic emergency. Prompt diagnosis and treatment are the primary determinants of mortality. During follow-up, the majority of patients who have been effectively treated die from hypovolemic shock and multiorgan failure. This article describes the clinical and procedural details of sixteen patients with ruptured aortic aneurysms treated endovascularly. In addition, it discusses the main factors contributing to the mortality of these patients.

METHOD

Patients who underwent endovascular treatment for acute aortic rupture at our center from October 2016 to March 2023 were included in this retrospective study.

RESULTS

A total of 16 patients underwent endovascular aneurysm repair (EVAR) or thoracic endovascular aneurysm repair (TEVAR) for acute aortic rupture. The patients' mean age was 73.06 years (range: 52-92), and 15 of them were male. The ruptures occurred in the abdominal aortic aneurysm in ten patients, in thoracic aortic aneurysm in three patients, in the isolated iliac artery aneurysm in two patients, and there was one case of non-aneurysmal aortic rupture. In our series, patients who presented with an impending, self-limited rupture and stable hemodynamic status had good prognostic outcomes. However, eight patients died due to multiorgan failure, hemorrhagic shock, disseminated intravascular coagulopathy, renal failure, or abdominal compartment syndrome. These patients generally had poor admission vital signs and low hemoglobin values. The most critical determinants for the success of the procedure are promptly stopping the bleeding, avoiding general anesthesia, and opting for blood product replacement instead of fluid replacement.

CONCLUSION

Each patient with ruptured aortic aneurysm should be managed according to the patient's hemodynamics at presentation, the size of the aneurysm, the suitability for percutaneous procedure, logistical factors, and the operator-center's experience.

Mitral-Tricuspid Regurgitation Change After Transcatheter Aortic Valve Implantation and Its Effect on Mortality and Hospitalization

OBJECTIVE

Moderate to severe mitral regurgitation (MR) and tricuspid regurgitation (TR) are present in approximately 20-60% of patients undergoing transcatheter aortic valve implantation (TAVI). This study aims to evaluate the impact of TAVI on MR and TR, pulmonary hypertension, and reverse cardiac remodeling in these patients.  Methods: Out of 240 patients who underwent TAVI, 79 who met the inclusion and exclusion criteria were analyzed.

RESULTS

In our study, 46.8% (n = 37) of the patients were male. Nineteen (24.1%) patients died within two years. Before TAVI, 34 (43%) patients had moderate-to-severe MR, which decreased to 18 (22.7%) after the procedure (P < 0.05). Similarly, the number of patients with moderate-to-severe TR decreased from 26 (32.9%) before TAVI to 12 (15%) after the procedure (P < 0.05). Of the patients, 50.6% (n = 40) did not require hospitalization after the procedure, while 25 were hospitalized once, 12 twice, and 2 three times. The mean systolic pulmonary artery pressure (sPAP) values of the patients decreased from 44.30 ± 14.42 mmHg before the procedure to 39.09 ± 11.77 mmHg after the procedure (Z=-3.506, P < 0.001). No correlation was found between changes in MR and TR grades after TAVI and mortality or hospitalization during follow-up. Furthermore, there was no statistically significant difference in tricuspid annular plane systolic excursion (TAPSE), free wall annular S' velocity, left atrial volume (LAV), or LAV index (LAVI) before and after TAVI.  Conclusion: There was a significant decrease in moderate-to-severe MR and TR after TAVI; however, this did not impact hospitalization or mortality rates. Additionally, no significant differences were observed in right ventricular systolic function or in LAV and LAVI before and after TAVI.

Atrial and ventricular arrhythmia predictors with electrocardiographic parameters in myocardial infarction with non-obstructive coronary artery disease (MINOCA)

BACKGROUND

The clinical importance and recognition of myocardial infarction with non-obstructive coronary artery disease (MINOCA) is increasing. Nevertheless, no studies are investigating the risk of atrial fibrillation and ventricular arrhythmia in MINOCA patients. This study aimed to determine the risk of arrhythmia with electrocardiographic predictors in MINOCA patients.

METHODS

In this study, patients diagnosed with MINOCA and stable out-patients without significant lesions in their coronary arteries were compared. Morphology-voltage-Pwave duration electrocardiography (MPV ECG) score was used to determine atrial arrhythmia risk. QT interval and QT dispersion Tpeak-Tend time and Tpeak-Tend/QT interval were used to determine ventricular arrhythmia risk.

RESULTS

A total of 155 patients were included in our study. Seventy-seven of these patients were in the MINOCA group. There was no statistically significant difference between the two groups in MPV ECG score (1.95 ± 1.03 vs 1.68 ± 1.14, p = 0.128). P-wave voltage, P-wave morphology and P-wave duration, which are components of the MPV ECG score, were not statistically significantly different. The QRS complex duration (90.21 ± 14.87 vs 82.99 ± 21.59 ms, p = 0.017), ST interval (271.95 ± 45.91 vs 302.31 ± 38.40 ms, p < 0.001), corrected QT interval (438.17 ± 43.80 vs 421.41 ± 28.39, p = 0.005) and QT dispersion (60.75 ± 22.77 vs 34.19 ± 12.95, p < 0.001) were statistically significantly higher in the MINOCA group. The Tpeak-Tend (89.53 ± 32.16 vs 65.22 ± 18.11, p < 0.001), Tpeak-Tend/QT interval (0.2306 ± 0.0813 vs 0.1676 ± 0.0470, p < 0.001) and Tpeak-Tend/corrected QT interval (0.2043 ± 0.6997 vs 0.1551 ± 0.4310, p < 0.001) ratios were also significantly higher in patients with MINOCA.

CONCLUSIONS

In the MINOCA patients, there was no increase in the risk of atrial fibrillation based on ECG predictors. However, it was shown that there could be a significant increase in the risk of ventricular arrhythmia. We believe this study could be helpful for specific recommendations concerning duration of hospitalisation and follow up in MINOCA patients.

Endovascular Therapy of Aortic Rupture Secondary to a Psoas Abscess

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.

Evaluation of the Transcatheter Aortic Valve Replacement Results in Patients with Borderline Aortic Annulus and the Impact of Under- or Oversizing the Valve

BACKGROUND

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.

METHODS

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.

RESULTS

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).

CONCLUSION

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.

The Relationship Between Sexual Activity and Heart Rate Variability in Menopausal Women

Background:

Menopause is an important life stage for women, which can bring along sexual and cardiac problems. Increased heart rate variability is an indicator of parasympathetic activity and is associated with mental and physical health and life expectancy. This study aimed to evaluate the effect of sexual activity (only penile–vaginal intercourse but not masturbation or non-coital sex with a partner) on heart rate variability in healthy menopausal women.

Methods:

We evaluated 130 menopausal patients aged 45-60 years, without chronic disease. The average weekly sexual activity numbers remembered in the last 1 year were questioned. The patients were divided into 2 groups according to the presence of sexual activity. The sexually active group was divided into subgroups as 1 per week and 2 or more per week. Menopause Rating Scale was applied for menopausal symptoms. Heart rate variability was analyzed from the 24-hour electrocardiography Holter recording.

Results:

Heart rate variability parameters were higher in the sexually active group than in the sexually inactive group (mean of the standard deviations of all the NN intervals for each 5 min segment of a 24-hour heart rate variability recording: P = .004; root mean square of differences between adjacent normal RR intervals, expressed in ms: P = .001; number of NN intervals exceeding 50 milliseconds: P = .011; percentage of adjacent RR intervals with a difference of duration >50 ms: P = .009; low frequency: P = .011; high frequency: P = .008, low frequency/high frequency: P = .018). When assessed by multiple linear regression analysis by adjusting for age, body mass index, and menopause duration, the variables mean of the standard deviations of all the NN intervals for each 5 min segment of a 24-hour heart rate variability recording, root mean square of differences between adjacent normal RR intervals, expressed in ms, and low frequency were independently associated with the number of sexual activities per week (B = 2.89 ± 1.02, 95% CI = 0.866-4.91, P = .005; B = 4.57 ± 1.83, 95% CI = 0.94-8.2, P = .014; and B = 1174.9 ± 592.2, 95% CI = 2.9-2346.9, P = .049, respectively).

Conclusion:

In healthy menopausal women, continued sexual activity with penile–vaginal intercourse is associated with better health outcomes on cardiac autonomic function through higher heart rate variability, an index of parasympathetic activity.

Characteristics of a large-scale cohort with accessory pathway(s): A cross-sectional retrospective study highlighting over a twenty-year experience

OBJECTIVE

Catheter ablation following electrophysiologic study (EPS) is the mainstay of diagnosis and treatment for patients with atrioventricular reentrant tachycardia (AVRT), demonstrating excellent long-term outcome and a low rate of complications. In this study, our aim was to assess our experience in patients with accessory pathway (AP) and to compare our data with the literature.

METHODS

We included 1,437 patients who were diagnosed and treated for AP in our hospital between 1998 and 2020. The demographic data of all the patients, AP location, and periprocedural results were recorded.

RESULTS

Of the 1,437 patients, 1,299 (90.4%) were men; and the mean age of the population was 26.67 years. The location of 1,418 APs were along the left free wall (647 [45.6%] patients), in the posteroseptal region (366 [25.3%] patients), in the anteroseptal region (290 [20.4%] patients), and along the right free wall (115 [8.1%] patients). The ratio of the second AP existence was 3.0% and AVNRT co-existence was 2.0%. A total of 55 (3.8%) patients had recurrent sessions for relapse. Our center's total success rate was 95.5%, and total complication rate was 0.26%.

CONCLUSION

According to our retrospective analysis, EPS is a highly functional tool in the diagnosis and management of arrhythmias such as AVRT for high-risk patient groups like military personnel with the aim of risk stratification and medical management.

Evaluation of percutaneous annuloplasty for treatment of functional mitral regurgitation: A retrospective study

OBJECTIVE

The management of severe functional mitral regurgitation (FMR) in patients with heart failure (HF) and low ejection fraction is controversial, but percutaneous transcatheter procedures are promising. In this retrospective analysis, we aimed to assess the efficacy of the Carillon Mitral Contour System in patients with "inoperable" severe FMR.

METHODS

Seventy three patients (mean age 66.89, range 31-90 years) with congestive heart failure (CHF), severe FMR, and reduced ejection fraction (<35%) who underwent Carillon device implantation were examined. The study group consisted of patients with successfully implanted devices whereas the control group comprised patients in whom the device could not be deployed. The primary endpoint was combined all-cause mortality and first hospitalization for HF (whichever came first).

RESULTS

The median (Q1, Q3) follow-up was 31 (11-49) months. The device was deployed successfully in 50 patients (implant group) and not in 23 patients (non-implant group). Both the primary endpoint and all-cause mortality were lower in the "implant" group, but the differences were not significant. The median to primary endpoint was 21 [95% confidence interval (CI) 8.8-33.2] and six (95% CI 0.1-11.9) months for the implant group and the non-implant group, respectively (p=0.078).

CONCLUSION

Carillon Mitral Contour System implantation is a safe procedure and results in the reduction of all-cause mortality and combined endpoint of mortality and hospitalizations for HF in inoperable patients with severe FMR and low ejection fraction, although the difference did not meet the significance level.

Relationship between the extent of coronary artery disease and in-stent restenosis in patients with acute ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

OBJECTIVE

The pathophysiological mechanism of in-stent restenosis (ISR) is different from atherosclerosis of native coronary arteries. The aim of this study was to evaluate the relationship between ISR and the extent of coronary artery disease (CAD), and to identify other risk factors associated with ISR in ST-segment elevation myocardial infarction (STEMI) patients.

METHODS

A total of 372 consecutive patients presenting with first acute STEMI who were successfully treated with primary percutaneous coronary intervention within 12 hours from the onset of symptoms and who had an angiographic follow-up at 3 months were included in the study. The extent of CAD was calculated using the Gensini score.

RESULTS

The incidence of ISR observed in our group of patients was 23.4% (n=87). The mean Gensini score was significantly higher in patients with ISR when compared with group without restenosis (69 [range: 51-90] vs 42 [range: 32-61]; p<0.001). The presence of diabetes mellitus, left ventricular ejection fraction (LVEF), and low-density lipoprotein cholesterol (LDL-C) level differed significantly between the 2 groups (p<0.05 for all). Stent diameter and stent length were found to be significantly different between the ISR group and the no-restenosis group (p<0.05 for both). In multivariate logistic regression analysis, the Gensini score, stent diameter, stent length, LVEF, and LDLC were independently associated with ISR.

CONCLUSION

Despite the differences in the underlying pathophysiological mechanism of ISR and native coronary atherosclerosis, patients with a greater extent of CAD should be considered candidates for future stent restenosis.
