Two methods are currently available for left atrial (LA) strain measurement by speckle tracking echocardiography, with two different reference timings for starting the analysis: QRS (QRS-LASr) and P wave (P-LASr). The aim of MASCOT HIT study was to define which of the two was more reproducible, more feasible, and less time consuming. In 26 expert centers, LA strain was analyzed by two different echocardiographers (young vs senior) in a blinded fashion. The study population included: healthy subjects, patients with arterial hypertension or aortic stenosis (LA pressure overload, group 2) and patients with mitral regurgitation or heart failure (LA volume–pressure overload, group 3). Difference between the inter-correlation coefficient (ICC) by the two echocardiographers using the two techniques, feasibility and analysis time of both methods were analyzed. A total of 938 subjects were included: 309 controls, 333 patients in group 2, and 296 patients in group 3. The ICC was comparable between QRS-LASr (0.93) and P-LASr (0.90). The young echocardiographers calculated QRS-LASr in 90% of cases, the expert ones in 95%. The feasibility of P-LASr was 85% by young echocardiographers and 88% by senior ones. QRS-LASr young median time was 110 s (interquartile range, IR, 78-149) vs senior 110 s (IR 78-155); for P-LASr, 120 s (IR 80-165) and 120 s (IR 90-161), respectively. LA strain was feasible in the majority of patients with similar reproducibility for both methods. QRS complex guaranteed a slightly higher feasibility and a lower time wasting compared to the use of P wave as the reference.

OBJECTIVES To compare the surgical and percutaneous edge-to-edge (EE) repair in patients with severe left ventricular (LV) dysfunction and secondary mitral regurgitation (MR). METHODS We reviewed the prospectively collected data of the first 120 consecutive patients (age: 65 ± 9.8 years, EF: 28 ± 8.2%) treated with surgical (65 patients) or percutaneous (55 patients) EE repair for severe secondary MR in our institution. Age (P = 0.005) and logistic European System for Cardiac Operative Risk Evaluation (P < 0.0001) were significantly higher in the MitraClip group. LVEF (P = 0.37), end-diastolic (P = 0.83) and end-systolic (P = 0.68) volumes and systolic pulmonary artery pressure (SPAP) (P = 0.58) were similar. The follow-up was 100% complete [median: 4 years; interquartile range (IQR): 2.2–7.2]. RESULTS The length of hospital stay was 10 days (IQR: 8–13) for surgery and 5 days (IQR: 3.9–7.8) for MitraClip (P < 0.0001). Hospital mortality (3 vs 0%, P = 0.49) and freedom from cardiac death at 4 years (80.8 ± 4.9% vs 79.1 ± 5.9%, P = 0.9) were not significantly different in the surgical and MitraClip group, respectively. Residual MR ≥ 2+ at hospital discharge was 7.6% for surgery and 29% for MitraClip (P = 0.002). At 4 years, freedom from MR ≥ 2+ (74.9 ± 5.6% vs 51.4 ± 7.4%, P = 0.01) and freedom from MR ≥ 3+ (92.8 ± 3.4% vs 68.1 ± 7%, P = 0.002) were both significantly higher in the surgical group. Multivariate analysis identified the use of MitraClip as an independent predictor of recurrence of MR ≥ 2+ [Hazard ratio (HR): 2.1, 95% confidence interval (CI): 1.1–3.9, P = 0.02] as well as of MR ≥ 3 (HR: 6.1, 95% CI: 1.5–24.3, P = 0.01). In the surgical group, no predictors of cardiac mortality were identified. In the MitraClip group, left ventricular end-diastolic diameter (HR: 1.1, 95% CI: 1–1.2, P = 0.005) and SPAP (HR: 1, 95% CI: 1–1.1, P = 0.005) were independent predictors of cardiac death at the follow-up. CONCLUSIONS MitraClip therapy is a safe therapeutic option in selected high-risk patients with secondary MR and relevant comorbidities. The surgical EE provides higher efficacy both postoperatively and at the mid-term follow-up.
We studied 111 consecutive patients (mean (SD) age 64 (9) years; 32 women) admitted to our coronary care unit with Braunwald class IIIB unstable angina: 33 had been taking statins for at least four weeks plus standard anti-ischaemic treatment (group 1: mean age 62 (9) years; seven women); the remaining 78 patients were taking standard anti-ischaemic treatment but not statins before admission (group 2: mean (SD) age 65 (9) years; 25 women). Clinical features were recorded for both groups (table 1). All participants gave their informed consent. The ethics committee of the Catholic University of Rome approved the study.

Background: Cardiology divisions reshaped their activities during the coronavirus disease 2019 (COVID-19) pandemic. This study aimed to analyze the organization of echocardiographic laboratories and echocardiography practice during the second wave of the COVID-19 pandemic in Italy, and the expectations for the post-COVID era. Methods: We analyzed two different time periods: the month of November during the second wave of the COVID-19 pandemic (2020) and the identical month during 2019 (November 2019). Results: During the second wave of the COVID-19 pandemic, the hospital activity was partially reduced in 42 (60%) and wholly interrupted in 3 (4%) echocardiographic laboratories, whereas outpatient echocardiographic activity was partially reduced in 41 (59%) and completely interrupted in 7 (10%) laboratories. We observed an important change in the organization of activities in the echocardiography laboratory which reduced the operator-risk and improved self-protection of operators by using appropriate personal protection equipment. Operators wore FFP2 in 58 centers (83%) during trans-thoracic echocardiography (TTE), in 65 centers (93%) during transesophageal echocardiography (TEE) and 63 centers (90%) during stress echocardiography. The second wave caused a significant reduction in number of echocardiographic exams, compared to November 2019 (from 513 ± 539 to 341 ± 299 exams per center, −34%, p < 0.001). On average, there was a significant increase in the outpatient waiting list for elective echocardiographic exams (from 32.0 ± 28.1 to 45.5 ± 44.9 days, +41%, p < 0.001), with a reduction of in-hospital waiting list (2.9 ± 2.4 to 2.4 ± 2.0 days, −17%, p < 0.001). We observed a large diffusion of point-of-care cardiac ultrasound (88%), with a significant increase of lung ultrasound usage in 30 centers (43%) during 2019, extended to all centers in 2020. Carbon dioxide production by examination is an indicator of the environmental impact of technology (100-fold less with echocardiography compared to other cardiac imaging techniques). It was ignored in 2019 by 100% of centers, and currently it is considered potentially crucial for decision-making in cardiac imaging by 65 centers (93%). Conclusions: In one year, major changes occurred in echocardiography practice and culture. The examination structure changed with extensive usage of point-of-care cardiac ultrasound and with lung ultrasound embedded by default in the TTE examination, as well as the COVID-19 testing.

The incidence of right-sided infective endocarditis (RSIE) is steadily increasing and it has been reported to be associated with high risk of embolic events (EE). Aim of our study was to identify the clinical characteristics of patients with RSIE complicated by PE. Indeed, the identification of patients at high risk of significant PE who will benefit from a more aggressive therapeutic strategy may improve the prognosis. From January 2015 to September 2020, 176 patients (Pts) in 6 centers were found to have definite RSIE complicated by PE. Advanced imaging for PE including computed tomography pulmonary angiography (CTPA) was performed in 28 pts (16%) who represent our study group (24 male, mean age 50.6 ±18.29 years). They all underwent transesophageal echocardiography (TEE), in 12 cases (43%) also three-dimensional (3D) TEE, and 27 patients (99%) had both TEE and transthoracic echocardiography (TTE). A total of 53 vegetations (V) were detected. In 18 pts (64%) two or more vegetations were found. Native tricuspid valve was the most frequently involved valve (38 V, 71.7%), followed by catheter (5 V, 9.4%), tricuspid valve prosthesis (4 V, 7.5%), chordae and papillary muscle (2 V, 3.8%) and one vegetation (9%) in each of the following: pulmonic valve, inferior vena cava, eustachian valve, and right atrium. The most common location for vegetations was the anterior leaflet of the tricuspid valve (19 V, 35.8 %) followed by the posterior leaflet (11 V, 20.8%). The most common vegetations morphology was raceme-like shaped (35.8%). Staphylococcus aureus (S. aureus) was the most common causative pathogen (14 pts, 50%). The incidence of PE was very high in patients with vegetation length above 1.5 cm (median 17.6±6.5 mm by TEE). Our results suggest that a routine CTPA should be advised in the presence of vegetations larger than 1.5 cm and with S. aureus infection. This behavior would identify patients at high risk of PE who will benefit from a more aggressive therapeutic strategy, leading to an improvement in the prognosis. Further prospective studies are required to better confirm our hypothesis.
Objective Patients with unstable angina (UA) and high C-reactive protein (CRP) have increased cardiovascular risk. Whether genetic factors such as the synonymous 1059G/C polymorphism within the exon 2 of the human CRP gene determine CRP levels and outcome is unclear. Methods In 105 consecutive patients with UA, we assessed the CRP 1059G/C polymorphism, CRP plasma levels and interleukin-6 production after in-vitro stimulation of whole blood with lipopolysaccharide (1 ng/ml). Coronary events during a 24-month follow-up were recorded. Results CRP levels (median, range) were significantly lower among C-allele carriers (2.3 mg/l, 0.5–26.9) than among GG homozygotes (5.9 mg/l, 0.8–72.12, P=0.009). Interleukin-6 production was lower in C-allele carriers (1645 pg/ml, 832.0–9522) than in GG homozygotes (3929 pg/ml, 670.8–10 582), (P=0.085). At follow-up, 1059C-allele carriers experienced fewer coronary events than 1059GG homozygotes (13 vs. 47%, P=0.021). At multivariable analysis, a CRP level >3 mg/l, but not the 1059G/C polymorphism, was an independent predictor of coronary events (odds ratio 10.04, 95% confidence interval 2.84–35.44, P=0.0002). Conclusion This study shows that the CRP synonymous 1059G/C polymorphism affects CRP levels. No independent association was, however, observed between this polymorphism and clinical outcome in UA.
