Google Scholar has released the 2019 version of Scholar Metrics just now. This release covers articles published in 2014–2018 and includes citations from all articles that were indexed in Google Scholar as of July 2019.
Below is the top 20 journals in the field of cardio-thoracic surgery (https://scholar.google.com/citations?view_op=top_venues&hl=en&vq=med_heartthoracicsurgery). The two metrics in the bracket are the h5-index and h5-median, which are the h-index for articles published in the last 5 complete years and the median number of citations for the articles that make up its h5-index.

This meta-analysis included 70 articles reporting on more than 100,000 patients who underwent surgical aortic valve replacement. The incidence of patient-prosthesis mismatch (PPM) was 53.7%. Moderate and severe PPM was associated with higher mortality, both early and late after surgery. The authors conclude that the implementation of surgical strategies to prevent PPM are important in order to reduce mortality rates.

In this editorial, Harrington and coauthors introduce the updated guidelines for statistical reporting in the New England Journal of Medicine, which can be accessed at https://www.nejm.org/author-center/new-manuscripts.
The authors went into detail about the requirement to replace P values with estimates of effects or association and 95% confidence intervals when neither the protocol nor the statistical analysis plan has specified methods used to adjust for multiplicity.

Abbott announced that its fourth-generation MitraClip device, MitraClip G4, was approved by the US Food and Drug Administration on July 15, 2019, to treat mitral regurgitation (MR) in a wider population of patients. The MitraClip G4 include new clip sizes and an enhanced leaflet grasping feature
- More flexibility with four unique clip sizes, including clips with a wider grasping area to provide additional treatment options
- Independently controlled grippers that better help with the grasp of one or both mitral leaflets during transcatheter mitral valve interventions
- Upgraded MitraClip catheter can be integrated with a commercially available pressure monitor to continuously track and confirm MR reduction during the implant procedure

Aortic valve repair is complex, and techniques must be tailored to the pathology. With this in mind, the author summarizes his core philosophy on aortic valve repair in 10 points:
- Be prepared!
- Know the geometry of the aortic valve
- Understand the echocardiographic analysis of the aortic valve
- Do not trust looks!
- Identify suitable substrates
- Keep the repair simple and reproducible
- Assess the repair result systematically
- Carefully consider the alternatives
- Follow your patients/Learn from your failures
- Share your results
Each point is discussed in more depth in this editorial.

Investigators reported the distribution of thoracic aortic growth in smokers based on longitudinal data of current and ex-smokers aged 50-70 years from the Danish Lung Cancer Screening Trial. Mean and 95th percentile of annual aortic growth of the ascending aortic and descending aortic diameters were calculated with the first and last noncontrast computed tomography scans during follow-up.
A total of 1,987 participants (56% male, mean age 57.4 ± 4.8 years) were included and followed for a median of 48 months. The ascending and descending aortic growth was approximately 0.1 mm/year and consistent with growth in the general population. The 95th percentile ranged from 0.42 to 0.47 mm/year, depending on sex and location. Larger aortic growth was associated with lower age, increased height, absence of medication for hypertension or hypercholesterolemia, and lower Agatston scores.

Hamandi and colleagues reviewed outcomes for 95 patients who underwent isolated tricuspid valve (TV) surgery between 2007 and 2017 at their institution. For 41% of patients, the procedure was reoperative, following either prior coronary artery bypass grafting or prior valve surgery. Valve repair was performed in over 70% of patients. Operative mortality was low, being 3.2% overall and with no mortality in the last 6 years studied (73 patients). The authors conclude that careful patient selection and current periprocedural management have improved morbidity and mortality of isolated TV surgery, and they suggest that these outcomes can serve as a benchmark for catheter-based TV interventions.
