Approximately 250,000 heart valve operations are performed annually worldwide. An intensive research and development effort has led to progressively more advanced heart valve prostheses. The Carpentier-Edwards...

The study examined effectiveness ofpharmaco-cold cardioplegia employing solutions of enhanced buffer capacity during surgery of obstructive hypertrophic cardiomyopathy in adult patients (N=51) operated during 2013-2018. In group 1 (N=28), the cardioplegia was performed with HTK (Custodiol) solution, whereas in group 2 (N=23), it was carried out with Bokeria —Boldyrev ACH solution. The mean, minimum, and maximum ages in group 1 were 46, 21, and 64 years, respectively; in group 2 — 42, 14, and 70 years, respectively. In both groups, the patients were subjected to myoectomy of exit pathway in the left ventricle ac...
CONCLUSIONS: This report on TAVR risk assessment within the VA system demonstrates that despite a large proportion of patients classified as prohibitive risk, TAVR was associated with favorable 30-day and 1-year all-cause mortality rates when compared with published outcomes from the STS/ACC TVT registry.

CONCLUSION: In patients undergoing transfemoral TAVR, transradial CBOT with the Oceanus balloon dilatation catheter was feasible and safe. A balloon length up to 200 cm allowed the use of this technique (from right or left radial access) in all patients regardless of patient height or the presence of a challenging vascular anatomy.

ConclusionsReimplantation for bicuspid aortic valve repair showed acceptable mid-term outcomes.
ConclusionsThere are opportunities to improve clinical outcomes of patients with high surgical risks and those undertaking heart valve procedures, as they tend to have poorer survival and higher risk in developing postsurgical complications.
AbstractBackgroundSurgical indications for moderate to severe tricuspid regurgitation (TR) during atrial septal defect (ASD) closure are still unclear. Additional tricuspid valve annuloplasty (TVP) can be beneficial to avoid postoperative persistent TR. Therefore, we compared the results of surgical ASD closure with or without additional TVP in patients who presented with moderate ‐to‐severe TR.MethodsBetween November 2009 and June 2016, 103 patients with ASD and moderate ‐to‐severe TR underwent surgical ASD closure without (n = 76, group 1) and with additional TVP (n = 27, group 2). Cli...
AbstractAimsSevere tricuspid regurgitation (TR) impairs prognosis in patients with left ‐sided heart failure (HF) with preserved (≥50%, HFpEF) and reduced ejection fraction (
