Balloon-assisted subintimal entry (BASE) in chronic total occlusion percutaneous coronary interventions.

BACKGROUND: There is limited data on the use of the balloon-assisted subintimal entry (BASE) technique in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We analyzed the baseline clinical and angiographic characteristics and outcomes of 155 CTO PCIs that utilized the BASE technique at 31 US and non-US centers between 2016 and 2023. RESULTS: The BASE technique was used in 155 (7.9%) of 1968 antegrade dissection and re-entry (ADR) cases performed during the study period. The mean age was 66 ± 10 years, 88.9% of the patients were men, and the prevalence of diabetes (44.6%), hypertension (90.5%), and dyslipidemia (88.7%) was high. Compared with 1813 ADR cases that did not use BASE, the target vessel of the BASE cases was more commonly the RCA and less commonly the LAD. Lesions requiring BASE had longer occlusion length (42 ± 23 vs. 37 ± 23 mm, p = 0.011), higher Japanese CTO (J-CTO) (3.4 ± 1.0 vs. 3.0 ± 1.1, p < 0.001) and PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention chronic total occlusion) (1.8 ± 1.0 vs. 1.5 ± 1.0, p = 0.008) scores, and were more likely to have proximal cap ambiguity, side branch at the proximal cap, blunt/no stump, moderate to severe calcification, and proximal tortuosity. Technical (71.6% vs. 75.5%, p = 0.334) and procedural success (71.6% vs. 72.8%, p = 0.821), as well as major adverse cardiac events (MACE) (1.3% vs. 4.1%, p = 0.124), were similar in ADR cases that used BASE and those that did not. CONCLUSIONS: The BASE technique is used in CTOs with longer occlusion length, higher J-CTO score, and more complex angiographic characteristics, and is associated with moderate success but also low MACE.

Ventricular and atrial functions assessed by speckle-tracking echocardiography in patients with human immunodeficiency virus.

PURPOSE: Antiretroviral therapy (ART) has dramatically changed the clinical manifestation of human immunodeficiency virus (HIV) associated cardiomyopathy from severe left ventricular (LV) systolic dysfunction to a pattern of subclinical cardiac dysfunction. The aim of this study was to evaluate by speckle tracking echocardiography (STE) LV, right ventricular (RV), and biatrial functions in HIV-infected patients under different ART combinations. METHODS: We consecutively included 128 HIV-infected patients (mean age 44.2 ± 10.1 years, 110 males) and 100 controls (mean age 42.1 ± 9.4 years, 83 males). Ventricular and atrial functions were assessed by both conventional and STE. RESULTS: Although there was not any significant difference in conventional echocardiographic variables, HIV-infected patients had significantly lower LV global longitudinal strain (GLS), RV GLS, left atrial (LA) reservoir and conduit strain, and right atrial conduit strain. HIV patients receiving integrase strand transfer inhibitors and protease inhibitors (PI) had significantly lower LV GLS and LA conduit strain, while patients receiving non-nucleoside reverse transcriptase inhibitors and PI had significantly lower RV GLS than controls. CD4 count at the time of echocardiography was strongly correlated with LV GLS (r = .619, P < .001) and RV GLS (r = .606, P < .001). CONCLUSION: Biventricular and atrial functions are subclinically impaired in HIV-infected patients. ART regimen may also affect myocardial functions.

The evaluation of right ventricle dyssynchrony by speckle tracking echocardiography in systemic sclerosis patients.

PURPOSE: Systemic sclerosis (SSc) is associated with right ventricle (RV) remodeling and dysfunction. The primary aim of this study was to evaluate RV dyssynchrony (RV-Dys) in SSc patients using two-dimensional speckle tracking echocardiography (2D-STE). METHODS: Fifty-five SSc patients with functional class I-II and 45 healthy controls were consecutively included and underwent 2D-STE. RV-Dys was defined as the standard deviation of time to peak strain of mid and basal segments of RV free wall and interventricular septum. SSc group was further classified according to the presence of pulmonary arterial hypertension (PAH). Patients with tricuspid regurgitant velocity >2.8 m/s with additional echocardiographic PAH signs were defined as SSc PAH (+). RESULTS: SSc patients had lower RV longitudinal strain (RV-LS) (-17.6 ± 4.6% vs. -20.8 ± 2.8%, p < 0.001) and greater RV-Dys (49.9 ± 25.4 ms vs 24.3 ± 11.8 ms, p = 0.006) than controls despite no significant difference in conventional echocardiographic variables regarding RV function. Although SSc PAH(+) patients had lower RV-LS and higher RV-Dys than SSc PAH(-) patients, the differences were not statistically significant. The only independent predictor of RV-Dys was RV-LS (ß:-0.324 [-3.89- -0.45]; p = 0.014). CONCLUSION: SSc patients had not only reduced RV-LS but also impaired RV synchronicity even as conventional echocardiographic variables were preserved.

The effect of cardiac rehabilitation on blood pressure, and on left atrial and ventricular functions in hypertensive patients.

PURPOSE: Hypertension is associated with left ventricular (LV) hypertrophy, impaired LV relaxation, and left atrial (LA) enlargement. Cardiac rehabilitation (CR) improves clinical outcomes in a broad spectrum of cardiac disease. The aim of our study was to determine the effect of CR on blood pressure (BP), and on LA and LV functions in hypertensive patients. METHODS: Thirty consecutive hypertensive patients who would undergo CR program, and 38 hypertensive patients who refused to undergo CR program were included. All patients underwent ambulatory BP monitoring and transthoracic echocardiography, which were repeated after completion of the CR program, or 12 weeks later in the control group. LA and LV functions were assessed by both speckle tracking and 3-dimensional echocardiography. N-terminal pro-brain natriuretic peptide (NT-proBNP) levels were assessed before and after CR. RESULTS: Although initial ambulatory BP values and NT-proBNP levels were similar between the groups, daily, day-time, and night-time BP and NT-proBNP were significantly lower in the CR group after rehabilitation. LA reservoir strain and LV global longitudinal strain of the CR group significantly increased after CR while no significant increase was observed in controls. CONCLUSION: CR improves LA and LV strain while lowering BP and should be encouraged in routine management of hypertensive patients.

Subacute aortic prosthetic mechanical valve thrombosis complicated with acute coronary syndrome.

A prosthetic valve thrombosis (PVT), which is a potentially fatal complication, refers to the presence of non-infective thrombotic material on a prosthetic valve apparatus, interfering with its function. Possible complications of a PVT include transient neurologic embolic events, cardiac arrest due to a stuck valve prosthesis, and cardio-embolic myocardial infarction (MI). The choice of treatments, including a redo surgery, a percutaneous coronary intervention (PCI), and a fibrinolysis with PVT or MI dosages, depends on the patient's clinical and hemodynamic status and thrombotic burden involving the prosthetic valve and surrounding tissues. An early postoperative mechanical valve thrombosis is associated with increased risks due to the need for unforeseen early redo surgery complications and excessive bleeding risk in case of thrombolytic therapy usage. Here, we present a fifty-seven-year old female patient who was admitted to the emergency department with the complaint of acute chest pain seven days after an aortic prosthetic mechanical valve implantation. The clinical presentation was consistent with ST segment elevated MI and echocardiography revealed a large mass on the recently implanted prosthetic aortic valve. Valvular thrombotic complications after heart valve replacement operations are associated with high morbidity and mortality rates. Efficient and urgent treatment is necessary. Considering the clinical status of the patient, we preferred fibrinolytic therapy rather than PCI or surgery. The aim of this case report was to show the efficiency and safety of low-dose slow-infusion fibrinolytic therapy in PVT complicated with acute coronary syndrome.

Is Dabigatran As Effective As Warfarin on Cardiac Thrombus in a Patient With Atrial Fibrillation? A Challenging Question.

Atrial fibrillation (AF) is an important risk factor for cardioembolic stroke. Warfarin is an effective treatment in reducing the risk of cardioembolic stroke in patients with AF. New anticoagulants have been widely using for stroke prophylaxis in patients with nonvalvular AF. Previous studies have suggested that thrombolytic therapy is effective treatment choice in patients with pulmonary embolisms. Warfarin therapy is also effective on prevention or treatment of cardiac thrombus in patients with AF. However, there are no evidence-based data on treatment of cardiac thrombus with new oral anticoagulants in patients with AF. In our case report, we reported an AF patient with cardiac thrombus and pulmonary embolism under dabigatran therapy.

Successful Treatment of Massive Pulmonary Embolism With Catheter-Directed Thrombolysis in a Patient With Lymphocele: A Rare Cause of Thromboembolism.

Pulmonary embolism is a frequent and mortal situation especially in high-risk patients. Although thrombolytics and anticoagulants are the main options in treatment, substantial portion of patients also have high bleeding risk. Therefore, new catheter-directed treatment strategies, such as ultrasound-assisted transcatheter thrombolysis, gain importance in treatment options for intermediate and high-risk patients. Here, we report a case of massive pulmonary embolism due to the iatrogenic lymphocele after a radical retropubic prostatectomy procedure. The usage of ultrasound-assisted transcatheter thrombolysis was successful in such a high-risk patient.

Effect of acute sleep deprivation on left atrial mechanics assessed by three-dimensional echocardiography.

BACKGROUND: Although sleep deprivation (SD) affects cardiovascular system in many ways, physio-pathological changes in cardiac chamber volume and function have not been described well. The aim of the present study was to investigate the effect of SD on left atrial (LA) and ventricular function with three-dimensional (3D) echocardiography. METHODS: Thirty-two healthy individuals (12 females, mean age 33.25 ± 8.18) were evaluated. Echocardiographic examination was performed once after a night of regular sleep and a night of sleep debt. Beside conventional parameters, 3D phasic volumes and function were measured using a commercially available 3D echocardiography system and offline analysis software. RESULTS: Mean sleep duration of the study group was 8.15 ± 2.19 h in the day of regular sleep and 2.56 ± 2.25 h in the day of sleep deprivation. There was a significant prolongation in deceleration time (180.83 ± 15.34 vs. 166.44 ± 26.12; p = 0.044) and increase in E/e' (6.95 ± 1.26 vs. 6.38 ± 0.85; p = 0.005). Among 3D measurements, the difference in left ventricular ejection fraction (EF), LA EF, LA reservoir function and LA active EF were not significant. Mean LA passive EF of the individuals was significantly lower after night shift (24.10 ± 7.66 vs. 31.49 ± 7.75; p = 0.006). CONCLUSION: Acute SD is associated with a reduction in LA passive emptying function in healthy adults. 3D-derived indices were sufficient to show subclinical diastolic dysfunction according to impairment in passive phase of LA ejection. Prospective large-scale studies are needed to enlighten this issue.

A Case of Iatrogenic Chordal Rupture after Transcatheter Aortic Valve Implantation Procedure Requiring a Second Valve.

Transcatheter aortic valve implantation (TAVI) has emerged as a therapeutic option for high-risk aortic stenosis. Malposition of the prosthesis and severe residual aortic regurgitation are known complications of the procedure, which might require a second valve implantation. Although the implantation of a second valve seems to be an effective method, very few data are available describing this technique. Herein is reported a case of iatrogenic chordal rupture in a TAVI procedure which required a second valve implantation due to dislodgment of the first prosthesis.

Effect of acute sleep deprivation on heart rate recovery in healthy young adults.

BACKGROUND: Sleep deprivation (SD) is known to be associated with increased incidence of adverse cardiovascular events, but underlying pathophysiological mechanism has not been clearly demonstrated. Autonomic nervous system plays an important role in the regulation of cardiovascular function, and impairment in this system is associated with increased cardiovascular mortality. The aim of the current study was to investigate the effect of acute SD on autonomic regulation of cardiac function by determining heart rate recovery (HRR). METHODS: Twenty-one healthy security officers and nine nurses (mean age 33.25 ± 8.18) were evaluated. Treadmill exercise test was applied once after a night with regular sleep and once after a night shift in hospital. The HRR was calculated as the reduction in heart rate from peak exercise to the 30th second (HRR30), 1st minute (HRR1), 2nd minute (HRR2), 3rd minute (HRR3), and 5th minute (HRR5). The change in blood pressure (BP) measurements was also determined. RESULTS: Exercise capacity of individuals with SD was significantly lower (10.96 ± 1.01 vs. 11.71 ± 1.30 metabolic equivalent task (MET)s; p = 0.002), and peak systolic BP was significantly higher (173.8 ± 16.3 vs. 166.2 ± 9.9; p = 0.019). There was a signicant difference in HRR30 (12.74 ± 6.19 vs. 17.66 ± 5.46; p = 0.003) and HRR1 (31 ± 6.49 vs. 36.10 ± 7.78; p = 0.004). The ratio of these indices to peak HR was also significantly lower with SD (HRR%30 8.04 ± 4.26 vs. 10.19 ± 3.21; p = 0.025 and HRR%1: 18.66 ± 4.43 vs. 20.98 ± 4.72; p = 0.013). The difference in other indices of HRR was not significant. CONCLUSION: Our findings suggest that SD blunts cardiovascular autonomic response, and consequences of this relation might be more pronounced in subjects who are exposed to sleeplessness regularly or in subjects with baseline cardiovascular disease.

Evaluation of cardiac function by two-dimensional speckle tracking echocardiography in ulcerative colitis patients.

PURPOSE: Although ulcerative colitis (UC) shows obvious similarities with other autoimmune diseases, cardiac consequences have not adequately introduced. The aim of our study was to evaluate left ventricular (LV) function in UC patients by using novel echocardiographic parameters. RESULTS: Forty-five UC patients (mean age 37, 18 female) and 90 age- and sex-matched healthy volunteers (mean age 40, 38 female) included in the study. The mean disease activity score according to partial Mayo score was 2.16 ± 2.13. Mean global longitudinal strain (GLS) and global longitudinal strain rate (GLSR) measurements were significantly lower (-21.16 ± 2.71 vs. -23.36 ± 3.34; p < 0.001 and -1.33 ± 0.24 vs. -1.43 ± 0.24; p = 0.037, respectively), whereas global circumferential (-22.67 ± 3.66 vs. -23.37 ± 3.99; p = 0.140) and global radial strain (43.07 ± 8.58 vs. 44.12 ± 9.32; p = 0.545) measurements of the LV were similar in patients with UC compared with controls. The correlation coefficient (r) between GLS and partial Mayo score was -0.578 (p < 0.001). CONCLUSION: Our study suggests that systolic cardiac deformation values are impaired in UC patients. Reduced GLS and GLSR might be an early indicator of cardiac involvement in this population.

Acute proximal left anterior descending artery occlusion with de Winter sign.

Prompt recognition of electrocardiographic signs of acute coronary occlusion is essential for timely restoration of flow. ST-segment elevation or new onset left bundle-branch block are the most common electrocardiographic changes seen in acute phase of coronary occlusion. However, some patients may present with atypical electrocardiographic signs, and early diagnosis of these patients may constitute a clinical challenge. Here, we report a 41-year-old man presenting with an atypical electrocardiographic manifestation despite angiographically confirmed acute thrombotic occlusion of proximal left anterior descending artery.

Left ventricular and atrial functions in hypertrophic cardiomyopathy patients with very high LVOT gradient: a speckle tracking echocardiographic study.

BACKGROUND: Determination of myocardial deformation (strain) by two-dimensional (2D) speckle tracking echocardiography (STE) is a new method for evaluating left ventricular (LV) regional function in patients with hypertrophic cardiomyopathy (HCM). The aim of this study was to assess LV and left atrial (LA) functions with 2DSTE in HCM patients and to investigate relation between strain analysis and LV outflow tract (LVOT) gradient. METHODS: Forty consecutive HCM patients (26 male, mean age: 47.7 ± 15.2 years), and 40 healthy volunteers (22 male, mean age: 46.6 ± 11.2 years) were included in the study. All subjects underwent a transthoracic echocardiography for evaluation of LV and LA functions with 2DSTE. The HCM patients were divided into 2 groups according to the presence of resting LVOT gradient >100 mmHg. RESULTS: Left ventricular global longitudinal strain (GLS), global radial strain (GRS), and global circumferential strain (GCS) were significantly lower in patients with HCM compared with controls (-20.3 ± 3.6% vs. -24.1 ± 3.4% P < 0.001, 38.1 ± 12.8% vs. 44.8 ± 10.2% P = 0.012, and -22.0 ± 4.4% vs. -23.9 ± 4.0% P = 0.045, respectively). Although basal and apical rotation were similar between the groups, mid-rotation was significantly clockwise in HCM patients (-1.53 ± 2.06° vs. 0.05 ± 1.7° P < 0.001). Both LA reservoir functions and LA conduit functions were significantly lower in HCM patients (21.6 ± 9.1% vs. 39.4 ± 10.6% P < 0.001, and 10.5 ± 4.3% vs. 15.7 ± 5.3%, P < 0.001). Fifteen patients had a resting LVOT gradient of >100 mmHg and they had significantly decreased GLS, twist and untwist compared to the HCM patients with lower resting LVOT gradient (-18.7 ± 2.3% vs. -21.2 ± 3.9% P = 0.016, 19.4 ± 4.3° vs. 23.5 ± 7.4° P = 0.038 and -94.0 ± 29.1°/sec vs. -134.9 ± 55.8°/sec, 0.005, respectively). Although basal and apical rotation were similar between the 2 groups, mid-rotation was significantly clockwise in HCM patients with higher LVOT gradient (-2.52 ± 1.76° vs. -0.96 ± 2.03°, P = 0.018). Correlation analysis revealed that LVOT peak velocity was associated with GLS (r = -0.358, P = 0.023), LV mid-rotation (r = -0.366, P = 0.024), and LV untwist (r = -0.401, P = 0.013). CONCLUSIONS: Left ventricular and LA functions are impaired in patients with HCM. 2DSTE is useful in determining patients with impaired myocardial mechanics. High LVOT gradient may be one of the responsible factors that trigger deterioration of LV longitudinal strain and twist mechanics in patients with HCM. Further studies are required to clarify the preliminary results of this study.

Neutrophil to lymphocyte and platelet to lymphocyte ratio in patients with dipper versus non-dipper hypertension.

BACKGROUND: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) are associated with worse outcome in various diseases. Non-dipping blood pressure pattern is associated with higher cardiovascular mortality. The aim of this study was to explore the association between NLR and PLR in patients with dipper versus non-dipper hypertension. METHODS: The study included 166 patients with hypertension. Eighty-three patients (40 male, mean age: 49.1 ± 10.5 years) had dipper hypertension, while 83 patients (41 male, mean age: 52.3 ± 12.7 years) had non-dipper hypertension. RESULTS: Baseline demographic characteristics were similar in both groups. Patients with non-dipper hypertension had significantly higher NLR compared to dipper hypertension (2.3 ± 0.9 versus 1.8 ± 0.5, p < 0.001). Patients with non-dipper hypertension had significantly higher PLR compared to dipper hypertension (117.7 ± 35.2 versus 100.9 ± 30.5, p = 0.001). In univariate analysis, hyperlipidemia, smoking, presence of diabetes, PLR more than 107 and NLR more than 1.89 were among predictors of dipper and non-dipper status. In logistic regression analyses, only hyperlipidemia (odds ratio: 2.96, CI: 1.22-7.13) and PLR more than 107 (odds ratio: 2.62, CI: 1.13-6.06) were independent predictors of dipper and non-dipper status. A PLR of 107 or higher predicted non-dipper status with a sensitivity of 66.3% and specificity of 68.7%. CONCLUSION: We demonstrated that patients with non-dipper hypertension had significantly higher NLR and PLR compared to dipper hypertension, which has not been reported previously. Moreover PLR more than 107 but not NLR was independent predictor of non-dipper status.

Regional myocardial dysfunction assessed by two-dimensional speckle tracking echocardiography in systemic sclerosis patients with fragmented QRS complexes.

BACKGROUND: The aim of the study was to explore the relation between regional myocardial dysfunction and fragmented QRS (fQRS) complexes in systemic sclerosis (SSc). METHODS: Fifty-three SSc patients and 26 controls were included. All subjects underwent speckle tracking echocardiography for evaluation of left ventricular (LV) function and ECG to check for fQRS complexes. RESULTS: SSc patients had significantly lower LV global longitudinal, radial and circumferential strain and twist compared to controls. Thirteen SSc patients had fQRS (DII, DIII, aVF leads in eleven patients and V1 to V5 leads in two patients) and they had significantly lower global longitudinal and circumferencial strain compared to SSc patients with normal QRS. The SSc patients with fQRS in DII, DIII, and aVF leads had impaired longitudinal strain and delay in time to peak longitudinal strain in inferior LV segments compared to those with normal QRS. CONCLUSION: fQRS is associated with lower strain measures in SSc patients indicating impairment in LV function.

Direct transapical implantation of an endocardial pacing lead to the left ventricle: an alternate pacing site after tricuspid valve replacement.

In this paper, we report an alternative approach for implantation of ventricular pacing lead for complete atrioventricular block after tricuspid valve replacement.

"Main Vessel-Oriented" Treatment Strategy Versus "Open Side Branch" Treatment Strategy in Acute Coronary Syndrome Patients With Culprit Bifurcation Lesions.

Percutaneous coronary intervention of bifurcation lesions is associated with an increased risk of complications in patients with acute coronary syndrome (ACS). The study aimed to evaluate the in-hospital outcomes of patients with ACS with culprit bifurcation lesions who were treated with either a "main vessel-oriented" (MVO) treatment strategy or an "open side branch" (OSB) treatment strategy. This retrospective study included 575 consecutive patients with ACS. "MVO" and "OSB" treatment strategies were defined as primary/urgent percutaneous coronary intervention procedures performed by either totally ignoring the side branch (SB) or trying to maintain both main vessel and SB open with thrombolysis in myocardial infarction 3 flow. Procedural success and major cardiac/cerebrovascular events during hospitalization were noted. MVO and OSB treatment strategies were performed on 384 and 191 patients, respectively. The procedural success rate was significantly higher in the OSB treatment strategy whereas major cardiac/cerebrovascular events rates were similar except for the contrast-induced nephropathy rate being slightly higher in OSB treatment strategy. Subgroup analysis revealed a significantly higher procedural success rate in OSB treatment strategy if the SB was located within the bifurcation core, especially in those where the diameter of SB was ≥2 mm. In conclusion, our results suggest a better procedural result with SB protection attempts in patients with ACS with a culprit bifurcation lesion if the SB is originating within the bifurcation core and its diameter is ≥2 mm. MVO treatment strategy may be preferred in most cases with minor SBs located distant to the bifurcation core because of the similar procedural success.

Exploring the role of adult attachment, major depression and childhood trauma in arterial stiffness: A preliminary study.

OBJECTIVE: Prior research indicates a noteworthy and intricate connection between depression and subclinical atherosclerosis. Nevertheless, the biological and psychological mechanisms that underlie this association are not yet fully understood. To address this gap, this exploratory study aimed to examine the relationship between active clinical depression and arterial stiffness (AS), with a particular focus on the potential mediating roles of attachment security and childhood trauma. METHODS: In this cross-sectional study, we examined 38 patients with active major depression free of dyslipidemia, diabetes mellitus, hypertension, and obesity and 32 healthy controls. All participants underwent blood tests, psychometric assessments, and AS measurements using the Mobil-O-Graph arteriograph system. AS severity was evaluated using an augmentation index (AIx) normalized to 75 beats/min. RESULTS: In the absence of defined clinical cardiovascular risk factors, there was no significant difference in AIx between individuals with depression and healthy controls (p = .75). Patients with longer intervals between depressive episodes had lower AIx (r = -0.44, p < .01). Insecure attachment and childhood trauma did not significantly associate with AIx in patients. Whereas insecure attachment was positively correlated with AIx only in healthy controls (r = 0.50, p = 01). CONCLUSIONS: Our analysis of established risk factors for atherosclerosis revealed that depression and childhood trauma had no significant relationship with AS. However, we did identify a novel finding: insecure attachment was significantly associated with AS severity in healthy adults without defined cardiovascular risk factors for the first time. To our knowledge, this is the first study to demonstrate this relationship.

The Impact of Cystic Fibrosis- and Noncystic Fibrosis-Bronchiectasis on Pulmonary Artery Wall Thickness and Right Heart Functions Assessed by Speckle-Tracking Echocardiography.

BACKGROUND: Right heart functions are affected in patients with bronchiectasis as a result of pulmonary hypertension induced by chronic hypoxemia. Pulmonary artery wall thickness has recently been introduced as a sign of intensive and prolonged inflammation. The aim of this study was to analyze right ventricular and right atrial functions and to mea-sure pulmonary artery wall thickness in patients with cystic fibrosis-bronch iecta sis in comparison to those with noncystic fibrosis-bronchiectasis and healthy individuals. METHODS: We studied 36 patients with cystic fibrosis-bronchiectasis, 34 patients with noncystic fibrosis-bronchiectasis, and 32 age- and sex-matched control subjects. Lung function tests were performed. All subjects underwent comprehensive echocardiographic evaluation including conventional, tissue Doppler, speckle-tracking, and pulmonary artery wall thickness measurements. RESULTS: Right ventricular global longitudinal strain and global longitudinal right atrial strain during ventricular systole decreased in cystic fibrosis-bronchiectasis group compared with noncystic fibrosis-bronchiectasis and control groups (P <.001, both). Conversely, pulmonary artery wall thickness was increased in cystic fibrosis-bronchiectasis group in comparison to other groups (P <.001). Moreover, right ventricular global longitudinal strain was lower and pulmonary artery wall thickness was higher in patients with airflow obstruction (P <.001 and P =.025, respectively) than in those without. Only right ventricular global longitudinal strain was significantly correlated with pulmonary function test parameters. The negative effect of cystic fibrosis on right ventricular and right atrial functions was independent of age, gender, and disease duration. CONCLUSION: Our study showed that right ventricular and right atrial functions were deteriorated and pulmonary artery wall was thickened in cystic fibrosis-bronchiectasis patients more than noncystic fibrosis-bronchiectasis patients. Right ventricular global longitudinal strain detected subclinical right ventricular dysfunction and was associated with the severity of pulmonary disease.

Contemporary In-Hospital Outcomes of Chronic Total Occlusion Percutaneous Coronary Interventions: Insights from the MENATA (Middle East, North Africa, Turkey, and Asia) Chapter of the PROGRESS-CTO Registry.

Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has been rapidly evolving in different parts of the world. We examined the clinical and angiographic characteristics and procedural outcomes of 1,079 consecutive CTO PCIs performed in 1,063 patients at 10 centers in the Middle East, North Africa, Turkey, and Asia regions between 2018 and 2022. The mean age was 61 ± 10 years and 82% of the patients were men. The prevalence of diabetes (49%) and previous PCI (50%) was high. The most common target vessel was the right coronary artery (51%), followed by the left anterior descending artery (33%) and the circumflex artery (15%). The mean Japanese CTO score was 2.1 ± 1.2 and mean PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) score was 1.2 ± 1.0. The technical and procedural success rates were high (91% and 90%, respectively) with a low incidence (1.6%) of in-hospital major adverse cardiac events. The incidence of perforation was 4.6% (n = 50): guidewire exit was the most common mechanism of perforation (48%) and 14 patients required pericardiocentesis (28%). Antegrade wire escalation was the most common crossing strategy used (91%), followed by retrograde approach (24%) and antegrade dissection and re-entry (12%). Median contrast volume, air kerma radiation dose, and fluoroscopy time were 300 (200 to 400) ml, 3.7 (2.0 to 6.3) Gy, and 40 (25 to 65) minutes, respectively. In conclusion, high success and acceptable complication rates are currently achieved at experienced centers in the Middle East, North Africa, Turkey, and Asia regions using a combination of crossing strategies.
