Risk of unfavorable outcomes after penile prosthesis implantation - results from a national registry (INSIST-ED).

Like all surgeries, penile prosthesis implantation (PPI) has the potential for both postoperative complications and suboptimal patient satisfaction. In order to assess risk factors for poor satisfaction, we reviewed patients who had been prospectively recruited in a national multi-institutional registry of penile prostheses procedures (INSIST-ED) from 2014 to 20121. Patient baseline characteristics and postoperative complications were recorded. The primary endpoint of this study was unfavorable outcomes after inflatable PPI, defined as significant postoperative complications (Clavien-Dindo ≥2) and/or Sexuality with Quality of Life and Sexuality with Penile Prosthesis (QoLSPP) scores below the 10th percentile. A total of 256 patients were included in the study. The median age was 60 years (IQR 56-67). The most common cause of erectile dysfunction (ED) was organic (42.2%), followed by pelvic surgery/radiotherapy (39.8%) and Peyronie's disease (18.0%). Postoperative complications were recorded in 9.6%. High-grade complications (Clavien ≥2) occurred in 4.7%. At 1-year follow-up, the median QoLSPP total score was 71 (IQR 65-76). In all, 14.8% of patients were classified as having experienced unfavorable outcomes because of significant postoperative complications and/or QoLSPP scores below the 10th percentile. Logistic regression analysis demonstrated patient age to be non-linearly associated with the risk of experiencing unfavorable outcomes. A U-shaped correlation showed a lower risk for younger and older patients and a higher risk for middle-aged men. ED etiology and surgical volume were not associated with PPI outcomes. Physicians should, therefore, be aware that middle-aged men may be at higher risk of being unsatisfied following PPI compared to both younger and older patients.

Intermediate-term oncological and functional outcomes in prostate cancer patients treated with perineal robot-assisted radical prostatectomy: A single center analysis.

Objective: In the last 10 years, robotic platforms allowed to resume of some alternative surgical approaches, including perineal robot-assisted radical prostatectomy (p-RARP). Herein, we present in detail the oncological and functional outcomes of patients who underwent p-RARP with a median follow-up of 30 months. Methods: Patients presenting low- or intermediate-risk prostate cancer and prostate volume up to 60 mL who underwent p-RARP between November 2018 and November 2022 were selected. Baseline, intraoperative, pathological, and postoperative data were collected and then analyzed. Results: Thirty-seven p-RARP cases were included. Such patients presented mean age of 62 years and a mean Charlson comorbidity index of 4. Body mass index of ≥25 kg/m2 was reported by 24 (64.9%) patients, as well as 7 (18.9%) patients reported a past surgical history. Mean prostate volume and median prostate-specific antigen were 41 mL and 6.2 ng/mL, respectively. The median operative time was 242 min. The positive surgical margin rate was 45.9%. In terms of postoperative complications, 10 patients reported complications with any grade; however, a single case (2.7%) of major (Clavien-Dindo grade ≥3) complication was observed. No patient with biochemical recurrence or distant metastasis was reported at 2 years of follow-up. Recovery of continence rates were 67.6%, 75.7%, and 92.9%, at 6 months, 12 months, and 24 months after surgery, respectively. Conclusion: p-RARP is a challenging but safe minimally invasive approach for selected patients with prostate cancer suitable for radical prostatectomy, showing outstanding functional recovery. Despite positive surgical margin rates being relatively high, no cases of biochemical recurrence or distant metastasis were reported after a median follow-up of 30 months.

Comprehensive echocardiographic assessment of right ventricular function, pulmonary arterial elastic properties and ventricular-vascular coupling in adult patients with repaired tetralogy of fallot: clinical significance of 3D derived indices.

We aimed to comprehensively analyze by three-dimensional speckle-tracking echocardiography (3DSTE) and Doppler echocardiography right ventricular (RV) performance, pulmonary arterial (PA) elastic properties and right ventricular-pulmonary artery coupling (RVPAC) in patients with repaired tetralogy of Fallot (rTOF) and assess the feasibility and clinical utility of related echocardiographic indices. Twenty-four adult patients with rTOF and twenty-four controls were studied. RV end-diastolic volume(3D-RVEDV), RV end-systolic volume(3D-RVESV), RV ejection fraction(3D-RVEF), RV longitudinal strain(3D-RVLS) and RV area strain(3D-RVAS) were calculated by 3DSTE. RV end-systolic area (RVESA) was obtained by planimetry. Pulmonary regurgitation (PR) was assessed as trivial/mild or significant by cardiac magnetic resonance (CMR) and color-Doppler. Pulmonary artery (PA) elastic properties were determined using two-dimensional/Doppler echocardiography. RV systolic pressure (RVSP) was measured using standard Doppler methods. RVPAC was assessed using various 3DSTE-derived parameters (3DRVAS/RVSP, 3DRVLS/RVESA, 3DRVAS/RVESV). Overall, 3DRVEF and 3DRVAS were impaired in rTOF patients compared with controls. PA pulsatility and capacitance were reduced (p = 0.003) and PA elastance was higher (p = 0.0007) compared to controls. PA elastance had a positive correlation with 3DRVEDV (r = 0.64, p = 0.002) and 3DRVAS (r = 0.51, p = 0.02). By ROC (receiver operating characteristics) analysis, 3DRVAS/RVESV, 3DRVAS/RVSP and 3DRVLS/RVESA cutoff values of 0.31%/mmHg, 0.57%/mmHg and 0.86%/mmHg, respectively, had 91%, 88% and 88% sensitivity and 81%, 81% and 79% specificity in identifying exercise capacity impairment. In rTOF patients increased 3DSTE-derived RV volumes and impaired RV ejection fraction and strain are associated with reduced PA pulsatility and capacitance and increased PA elastance. 3DSTE-derived RVPAC parameters using different afterload-markers are accurate indices of exercise capacity.

Peculiar clinical and diagnostic features of infective endocarditis in Yemen: Comparative analysis with a Western University Hospital.

The aim of this study was to describe the pattern, characteristics, and outcomes of infective endocarditis (IE) in Yemen and compare the results with the findings of a Western university hospital. Patients (pts) with a final diagnosis of IE observed in Al-Thawra Sanaa Cardiac Center were prospectively enrolled in 1-year time period. Clinical and diagnostic findings were compared to clinical and diagnostic data of 50 pts with IE observed at Sapienza University Hospital in Rome, Italy. The mean age was 38 ± 6. Predisposing factors for IE were rheumatic heart disease (RHD) in 34 pts (68%), congenital heart disease in 9 pts (18%), prosthetic valve IE in 4 pts (8%), and previous IE in 3 pts (6%). Transthoracic echocardiography (TTE) was done in 50 pts and transesophageal echocardiography (TEE) in 25. Blood cultures were taken in all pts and were positive in 3 pts (6%) and negative in 47 (94%). TTE was positive in 34/50 pts (68%) and TEE in 20/25 (80%). Compared to Sapienza University pts, Al-Thawra Cardiac Center pts had a younger age (p = 0.003), more predisposing RHD (p = 0.0004), less prosthetic heart valves IE (p = 0.002), and more negative blood cultures (p = 0.0001). IE is still a common disease in Yemen among RHD pts and affects the younger age group. It has severe complications which need early diagnosis and proper management. Echocardiography is of prime diagnostic value in the absence of positive blood cultures. An effort should be made to prevent rheumatic fever and RHD.

Which patient may benefit the most from penile prosthesis implantation?

BACKGROUND: Penile prosthesis implantation has been associated with overall good functional outcomes. Of relevance, some patients reported higher level of satisfaction and quality of life. AIM: We investigated the profile of the patients who may benefit the most from penile prosthesis implantation. MATERIALS AND METHODS: Data from a national multi-institutional registry of penile prostheses including patients treated from 2014 to 2017 in Italy (Italian Nationwide Systematic Inventarization of Surgical Treatment for Erectile Dysfunction) were analyzed. All data have been prospectively recorded by 45 surgeons on a dedicated website (www.registro.andrologiaitaliana.it) and revised by a single data manager. Patients' baseline characteristics were recorded. In order to simultaneously evaluate perceived penile prosthesis function and quality of life, all patients were re-assessed at 1-year follow-up using the validated questionnaire Quality of Life and Sexuality with Penile Prosthesis. High quality of life after surgery was defined as a score higher than the 75th percentile in each of the subdomains of the Quality of Life and Sexuality with Penile Prosthesis questionnaire. Logistic regression analysis tested the association between clinical characteristics and high quality of life after penile prosthesis implantation. RESULTS: Follow-up data were available for 285 patients (median age 60 years; interquartile range: 56-67) who underwent penile prosthesis implantation. Erectile dysfunction etiology was organic in 40% (114), pelvic surgery/radiotherapy in 39% (111), and Peyronie's disease in 21% (60) of the cases. Patients showed good overall Quality of Life and Sexuality with Penile Prosthesis scores at 1-year follow-up for functional (22/25), personal (13/15), relational (17/20), and social (13/15) domains. Overall, 27.0% (77) of patients achieved scores consistent with the high quality of life definition. These patients did not differ in terms of median age (60 vs. 62), type of prosthesis (inflatable penile prostheses: 95% in both of the cases), and post-operative complications (10% vs. 14%) than those with lower quality of life score (all p > 0.1). At logistic regression analysis, erectile dysfunction etiology was the only factor independently associated with high quality of life at 1 year after surgery (p = 0.02). Patients treated for Peyronie's disease (odds ratio: 2.62; p = 0.01; 95% confidence interval: 1.20-5.74) were more likely to report better outcomes after accounting for age, post-operative complications, and surgical volume. CONCLUSION: Penile prosthesis implantation is associated with an overall good quality of life. The subset of patients affected by erectile dysfunction secondary to Peyronie's disease seemed to benefit the most from penile prosthesis implantation in terms of functional outcomes, relationship with their partners and the outside world, and perceived self-image. The systematic use of validated questionnaires specifically addressed at evaluating quality of life and satisfaction after penile prosthesis implantation should be further implemented in future studies to better define the predictors of optimal satisfaction after penile prosthesis implantation.

Xi Nerve-sparing Robotic Radical Perineal Prostatectomy: European Single-center Technique and Outcomes.

Background: Radical prostatectomy (RP) represents the standard of care for the treatment of patients with organ-confined prostatic cancer. Historically, perineal RP has been described as the first surgical approach for the complete removal of the prostatic gland. In the past years, robotic techniques provided some technical advantages that allow resuming alternative approaches, such as robotic radical perineal prostatectomy (r-RPP). Objective: To present in detail the technique of Xi nerve-sparing r-RPP and to report perioperative, oncological, and functional outcomes from a European tertiary center. Design setting and participants: Patients with low- or intermediate-risk prostatic cancer not suitable for active surveillance and prostate volume up to 60 ml who underwent r-RPP between November 2018 and December 2020 were identified. Surgical procedure: All patients underwent Xi nerve-sparing r-RPP. Measurements: Baseline characteristics and intraoperative, pathological, and postoperative data were collected and analyzed. The complications were reported according to the standardized methodology to report complications proposed by European Association of Urology guidelines. Results and limitations: Overall, our series included 26 patients who underwent r-RPP. Patients' median age was 62.5 yr. Thirteen (50%) and eight (30.7%) patients showed a body mass index (BMI) of 25-30 and >30, respectively. A history of past surgical procedures was present in seven (26.8%) patients. The median prostate volume was 40 (interquartile range [IQR]: 28-52) ml. The median operative time and blood lost were 246 (IQR: 230-268) min and 275 (IQR: 200-400) ml, respectively. Overall, four (15.4%) patients reported intraoperative complications and five (19.2%) reported postoperative complications, with one (3.8%) reporting major complications (Clavien-Dindo ≥3). No patient with biochemical recurrence (BCR) was reported at 1 yr of follow-up. Continence rates were 73.0%, 84.6%, and 92.3%, respectively, at 3, 6, and 12 mo after surgery. Erectile potency recovery rates were 57.1%, 66.6%, and 80.9% at 3, 6, and 12 mo of follow-up, respectively. Conclusions: Xi r-RPP is a challenging but safe minimally invasive approach for selected patients. No patient reported BCR at 12 mo. The choice of the surgical approach for RP is likely to be based on the patient's characteristics as well as the surgeon's preferences. Patient summary: Our study suggests that Xi radical perineal prostatectomy is a safe minimally invasive approach for patients with low- or intermediate-risk prostatic cancer, and complex abdominal surgical history or comorbidities.

Analysis of the Physico-Chemical, Mechanical and Biological Properties of Crosslinked Type-I Collagen from Horse Tendon: Towards the Development of Ideal Scaffolding Material for Urethral Regeneration.

Urethral stenosis is a pathological condition that consists in the narrowing of the urethral lumen because of the formation of scar tissue. Unfortunately, none of the current surgical approaches represent an optimal solution because of the high stricture recurrence rate. In this context, we preliminarily explored the potential of an insoluble type-I collagen from horse tendon as scaffolding material for the development of innovative devices for the regeneration of injured urethral tracts. Non-porous collagen-based substrates were produced and optimized, in terms of crosslinking density of the macromolecular structure, to either provide mechanical properties compliant with the urinary tract physiological stress and better sustain tissue regeneration. The effect of the adopted crosslinking strategy on the protein integrity and on the substrate physical-chemical, mechanical and biological properties was investigated in comparison with a decellularized matrix from porcine small intestinal submucosa (SIS patch), an extensively used xenograft licensed for clinical use in urology. The optimized production protocols allowed the preservation of the type I collagen native structure and the realization of a substrate with appealing end-use properties. The biological response, preliminarily investigated by immunofluorescence experiments on human adult renal stem/progenitor cells until 28 days, showed the formation of a stem-cell monolayer within 14 days and the onset of spheroids within 28 days. These results suggested the great potential of the collagen-based material for the development of scaffolds for urethral plate regeneration and for in vitro cellular studies.

Myocardial strain impairment, heterozygous familial hypercholesterolemia and systemic arterial hypertension: Is there a link?

Dyslipidemia is known as a strong risk factor for premature atherosclerotic cardiovascular disease and increased morbidity and mortality and can have an adverse effect on left ventricular function due to direct or indirect macrovascular and/or microvascular damage. Speckle-tracking echocardiography allows the assessment of subclinical cardiac dysfunction in different diseases on the basis of myocardial deformation indices, and decrease in longitudinal and circumferential strain was shown in patients with heterozygous familial hypercholesterolemia (heFH) without comorbidities. In this issue of the journal a new study presents the results in a well-defined population which included asymptomatic treatment-naive heFH individuals without known coronary/peripheral arterial disease, with normal left ventricular ejection fraction and no other risk factors as formal arterial hypertension or diabetes mellitus. A slight impairment of global longitudinal strain was present, despite normal standard echocardiographic parameters. Also, the higher rise in systolic and diastolic blood pressure of heHF patients during exercise treadmill test might reflect early preclinical hypertension. High cholesterol level may have produced endothelial dysfunction, which has been shown to be related to the extent of atherosclerotic process and cardiovascular damage. Relevant findings are reported on left ventricular strain reduction and increase in systolic/diastolic blood pressure in asymptomatic heFH males. The relationship between myocardial strain impairment and developing systemic arterial hypertension in hypercholesterolemic patients could be the subject of further subsequent investigation.

Robotic radical perineal prostatectomy: tradition and evolution in the robotic era.

PURPOSE OF REVIEW: To provide an updated review of robotic radical perineal prostatectomy (r-RPP) with emphasis on the recent advances in terms of surgical technique, outcomes, and new robotic platforms. RECENT FINDING: The technological innovations in the urological field have been applied to radical prostatectomy with the aim of preserving important anatomical structures and reduce patients' morbidity and mortality. In recent years, robotic surgery contributed to resurge radical perineal prostatectomy. In 2014, the Cleveland Clinic group was the first to demonstrate the utility of a robotic approach in RPP. To date, the majority of the reported studies showed that r-RPP has noninferior perioperative, short-term oncological, and functional outcomes compared with the traditional robot-assisted radical prostatectomy (RARP). Given these benefits, r-RPP is a promising approach in selected patients, such as obese ones. Moreover, robotic perineal pelvic lymph node dissection performed through the same incision of r-RPP and the new Single-Port (SP) Robotic System represent further steps towards the overcoming of some intrinsic limitation of this surgical approach making this technique suitable for a larger number of patients with prostatic cancer. SUMMARY: Overall, r-RPP represents a reliable and effective novel surgical technique. However, more studies with long-term follow-up are needed to clarify the advantages over RARP.

Heart, COVID-19, and echocardiography.

Although clinical manifestations of coronavirus disease of 2019 (COVID-19) mainly consist of respiratory symptoms, a severe cardiovascular damage may occur. Moreover, previous studies reported a correlation of cardiovascular metabolic diseases with severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), and actually, many COVID-19 patients show comorbidities (systemic hypertension, cardio-cerebrovascular disease, and diabetes) and have a raised risk of death. The purpose of this review is to focus the cardiovascular effects of 2019-nCoV on the base of the most recent specific literature and previous learnings from SARS and MERS and analyze the potential role of echocardiography during the current critical period and short- and long-term follow-up.

Functional outcome and quality of life evaluation of graciloplasty for the treatment of complex recto-vaginal and recto-urethral fistulas.

Recto-vaginal (RVF) and recto-urethral (RUF) fistulas are infrequent but disabling conditions that severely affect patients' quality of life. Considering the high recurrence rate after conservative approaches, the best surgical treatment is still challenging. The aim of this study was to evaluate the outcome of graciloplasty to treat patients with complex RVF or RUF, and to investigate its effect on the quality of life. Fourteen patients with RVF and RUF who underwent graciloplasty between 2003 and 2017 were retrospectively enrolled. The main outcome was the healing rate of fistulas. Postoperative patients satisfaction was evaluated administering the Clinical Patient Grading Assessment Scale (CPGAS), SF-36 questionnaires and Changes in Sexual Functioning (CSF) questionnaires. The Wexner score was calculated in case of preoperative faecal incontinence. RVF and RUF were iatrogenic in 11 patients and due to Crohn's disease in 3 cases. After 1 year of follow-up (IQR 10-14 months), the success rate of the procedure was 78%. Out of three patients with RVF due to Crohn's disease, two healed after the procedure. Six months after surgery, all eight SF-36 domains significantly improved except for "body pain"; CSF score significantly increased from 35.5 (IQR 31-38.7) to 44 (IQR 37.7-48.5); CPGAS score improved from a median value of 0 (IQR 0-0) to 4 (IQR 3.2-4). The Wexner score was calculated only in 5 patients with preoperative faecal incontinence and it significantly decreased from a median value of 12 (IQR 11-14) to 5 (IQR 4-5). Graciloplasty could be considered as a first option treatment for complex or recurrent RVF and RUF. It shows a good healing rate even in case of unfavourable factors like Crohn's disease.

Assessment of Biventricular Function by Three-Dimensional Speckle Tracking Echocardiography in Adolescents and Young Adults with Human Immunodeficiency Virus Infection: A Pilot Study.

BACKGROUND: The purpose of the study was to assess biventricular parameters of wall deformation with three-dimensional speckle tracking echocardiography (3DSTE) in adolescents and young adults with human immunodeficiency virus (HIV) infection on antiretroviral therapy in order to detect a possible subclinical myocardial dysfunction. METHODS: Twenty-one patients aged 12-39 years with HIV, 21 normal controls of the same age and sex, and 21 patients with idiopathic nonischemic dilated cardiomyopathy (DCM) were studied with 3DSTE. All HIV patients were stable in terms of HIV infection, with no history of heart disease or other chronic systemic disease except HIV infection, and were on highly active antiretroviral therapy with good immunological control. Standard echocardiographic measures of left ventricular (LV)-right ventricular (RV) function were assessed. 3D LV global longitudinal strain (GLS), circumferential strain, radial strain, and LV twist were calculated. Global area strain (GAS) was calculated by 3DSTE as percentage variation in surface area defined by the longitudinal and circumferential strain vectors. 3D RV global and free-wall longitudinal strain (FWLS) were obtained. RESULTS: LV GLS and GAS were lower in HIV patients compared to normal controls (p = 0.002, and p = 0.01, respectively). There were no significant differences in LV ejection fractions between the groups. There was a weak positive correlation between LV GLS and age (r = 0.215, p = 0.034) and a weak negative correlation between LV GLS and nadir-CD4 T-cells count (r = 0.198, p = 0.043). DCM patients had more marked and widespread reduction in LV GLS and GAS compared to controls (p < 0.001), whereas in HIV patients LV strain impairment (p < 0.05) was more localized in basal and apical regions. RV FWLS was significantly reduced in HIV patients when compared with the control group (p = 0.03). No patient had pulmonary systolic pressure higher than 35 mm Hg. CONCLUSIONS: 3DSTE may help to identify HIV patients at high cardiovascular risk allowing early detection of biventricular dysfunction in the presence of normal LV ejection fraction and in the absence of pulmonary hypertension. LV strain impairment in HIV patients is less prominent and widespread compared to DCM patients.

Patent Foramen Ovale: Pivotal Role of Transesophageal Echocardiography in the Indications for Closure, Assessment of Varying Anatomies and Post-procedure Follow-up.

Patent foramen ovale (PFO) is present in 15%-30% of the general population and has been associated with various pathologic states, including cryptogenic stroke, platypnea-orthodeoxia syndrome, decompression sickness and migraine with auras. Transesophageal echocardiography (TEE) has a major role in the diagnostic evaluation of PFO, as well as in the post-procedural assessment after transcatheter closure. The goals of this article were to synthesize the echocardiographic transesophageal techniques required for accurate PFO diagnosis and careful anatomic assessment of its anatomic variants, to focus TEE indications for device closure as complementary to clinical indications and to assess the role of TEE in the post-procedure follow-up.

Right atrial function by speckle tracking echocardiography in atrial septal defect: Prediction of atrial fibrillation.

BACKGROUND: Most antiarrhythmic interventional therapies for atrial fibrillation (AF) have been provided with special focus on the treatment of left-sided valvular disease and enlarged left atrium but few studies have assessed AF associated with congenital heart disease and dilated right atrium. HYPOTHESIS: We hypothesized that right atrial (RA) function assessed by two-dimensional (2DSTE) and three-dimensional (3DSTE) speckle-tracking echocardiography in patients with atrial septal defect (ASD) before and after percutaneous trancatheter closure could predict paroxysmal atrial fibrillation (PAF) development. METHODS: Seventy-three patients with hemodynamically significant secundum ASD were prospectively studied and followed up for 6 months after occluder insertion and compared with a normal age-matched group (n = 73). A subgroup of 17 patients who developed PAF after device implantation was also studied. RA peak global longitudinal strain (PS) was determined using 2DSTE. Standard deviations (SDs) of times to peak strain (TPS) were calculated as indices of dyssynchrony. RA volumes, emptying fraction (EF), and expansion index (EI) were determined using 3DSTE. RESULTS: RA-PS, EF, and EI (pre-closure values) were reduced in patients with atrial devices compared with controls, and further reductions were observed in patients with PAF. Pre-closure 3D-RA-EI (P = 0.009) and RA-TPS (P = 0.023) were independent predictors of PAF by multivariate analysis after adjustment for age and left atrial dysfunction. The areas under the ROC-curve (AUC) for 3D-RA-EI, RA-PS, RA-TPS (pre-closure values) showed high discriminative values(from 0.76 to 0.85) in predicting PAF. By combining 3D-RA-EI and RA-TPS, the AUC increased to 0.90. CONCLUSIONS: Two-dimensional and three-dimensional speckle tracking echocardiography was clinically helpful in ASD patients in revealing right atrial dilatation and dysfunction pre-existent to device closure and associated with PAF development. RA parameters had a higher association with PAF compared to both the size of the implanted device and left atrial indices.

Biventricular assessment of light-chain amyloidosis using 3D speckle tracking echocardiography: Differentiation from other forms of myocardial hypertrophy.

BACKGROUND: Given that in patients with cardiac amyloidosis (CA), deposition of amyloid protein is not restricted to the left ventricular (LV) myocardium, it can be hypothesized that the diagnostic value of deformation mechanics would be enhanced by considering right ventricular (RV) strain measures. The aim of the present study was to examine the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiograph (3DSTE) to diagnose cardiac amyloidosis and differentiate this disease from other forms of myocardial hypertrophy. METHODS: Twenty-three patients with biopsy-proven light-chain (AL) amyloidosis, 23 patients with systemic arterial hypertension (HTN), 23 patients with hypertrophic cardiomyopathy (HCM), 23 athletes and 23 normal controls were prospectively studied by conventional echocardiography and 3DSTE. LV longitudinal strain (LV LS), LV circumferential strain (LV CS), RV global longitudinal strain and RV free-wall longitudinal strain (RV FW LS) were obtained by 3DSTE, as well as LV rotation and rotational velocities. RESULTS: LV and RV longitudinal strains were reduced in cardiac amyloidosis (CA) patients compared to controls. By multivariate analysis, LV basal LS (p = 0.002), LV peak basal rotation (p = 0.003), and RV basal FW LS (p = 0.014) were independently associated with CA in the overall population. A significant improvement in global χ2 value was noted with RV 3D-strain parameters over only LV-3DSTE + conventional indices for detection of CA (p < 0.001). Comparison of ROC curves showed that the AUC using combined LV basal LS, LV basal rotation and RV basal FW LS had a higher discriminative value than the other echocardiographic parameters used for detecting CA (AUC 0.93, 95%CI 0.81-0.97). CONCLUSIONS: Three-dimensional speckle tracking echocardiography reveals regional and global biventricular dysfunction in CA. Assessment of RV ventricular dysfunction has an additive value in differentiating CA from other causes of myocardial wall thickening.

Dataset on the use of 3D speckle tracking echocardiography in light-chain amyloidosis.

The dataset presented in this article is related to the research article entitled "Biventricular assessment of light-chain amyloidosis using 3D speckle tracking echocardiography: Differentiation from other forms of myocardial hypertrophy" (Vitarelli et al., 2018) [1], which examined the potential utility of left ventricular (LV) and right ventricular (RV) deformation and rotational parameters derived from three-dimensional speckle-tracking echocardiography (3DSTE) to diagnose cardiac amyloidosis(CA) and differentiate this disease from other forms of myocardial hypertrophy. The combined assessment of LV basal longitudinal strain, LV basal rotation and RV basal longitudinal strain had a high discriminative power for detecting CA. The data of this study provides more understanding on the value of LV 3DSTE deformation parameters as well as RV parameters in this particular cardiomyopathy.

Bi-Atrial Function before and after Percutaneous Closure of Atrial Septum in Patients with and without Paroxysmal Atrial Fibrillation: A 2-D and 3-D Speckle Tracking Echocardiographic Study.

Our aim was to analyze atrial function with 2-D (2-D-STE) and 3-D (3-D-STE) speckle tracking echocardiography in patients with atrial septal devices and paroxysmal atrial fibrillation (PAF). One hundred sixteen patients and a subgroup of 22 patients who developed PAF after device insertion were studied. Left atrial and right atrial peak longitudinal strain and standard deviations of time to peak strain (TPS) were calculated using 2-D-STE. The left atrial/right atrial emptying fraction and expansion index were determined using 3-D-STE. By multivariate analysis, pre-closure 3-D right atrial expansion index, left atrial time to peak strain, and 3-D left atrial expansion index were independently associated with PAF. Compared with the other indices, receiver operating characteristic analysis revealed better diagnostic accuracy for the combination of pre-closure time to peak strain and 3-D expansion index in detecting PAF. Patients with atrial septal devices have pre-existing left and right atrial dilation and dysfunction as assessed by 2-D-STE and 3-D-STE that appear sensitive for the stratification of PAF risk in this population.
