Long-term Outcomes of Stand-Alone Maze IV for Persistent or Long-standing Persistent Atrial Fibrillation
ConclusionsThis study confirmed the safety and efficacy in the long term (7 years) of the stand-alone Cox-Maze IV surgical procedure for persistent or long-standing persistent AF. Indeed, more than 70% of the patients were in sinus rhythm off class I or III AADs and off oral anticoagulation.Visual Abstract

Long-term outcomes of stand-alone Maze IV for persistent/long-standing persistent atrial fibrillation
ConclusionsThis study confirmed the safety and efficacy at long-term (7 years) of the stand-alone Maze IV surgical procedure for persistent/long-standing persistent AF. Indeed, more than 70% of the pts were in SR off class I/III AADs and off oral anticoagulation.Graphical abstract

Mechanical Versus Bioprosthetic Aortic Valve Replacement in Patients Aged 50 Years and Younger
ConclusionsThe increased risk of reoperation for bAVR and major bleeding incidents for mAVR was not reflected in midterm and long-term survival differences between the two groups. Our results suggest that bAVR may be an acceptable prosthesis choice for some patients aged 50 years and younger, although the results should be taken with caution.Visual Abstract

Minimally Invasive Approaches to Surgical Aortic Valve Replacement: A Meta-Analysis
ConclusionsMinimally invasive approaches to AVR yield excellent outcomes in high volume centers. They reduce hospital stay and incidence of post-operative atrial fibrillation, and, therefore, should be considered in patients undergoing AVR. However, the operative approach should be selected according to surgeon’s technical expertise and what is best for specific patient profile.

Determinants of Reverse Remodeling of the Left Atrium After Transaortic Myectomy
ConclusionsLeft atrial volume decreases significantly after surgical relief of left ventricular outflow tract obstruction. Early changes likely reflect lower LA pressure due to gradient relief and abolishment of mitral regurgitation, and late reduction suggests continued reverse remodeling.

Use of an Automated Suture Fastening Device in Minimally Invasive Aortic Valve Replacement
ConclusionsIn mAVR, the CK device was associated with reduced aortic cross-clamp time while providing equivalent clinical outcomes. Larger studies are needed to confirm the efficacy, safety, and cost-effectiveness of the CK device in minimally invasive aortic valve surgery.

Outcomes in 937 Intermediate-Risk Patients Undergoing Surgical Aortic Valve Replacement in PARTNER-2A
Conclusions In this adjudicated prospective study, SAVR in intermediate-risk patients had excellent results at 2 years. However, there were more in-hospital strokes than expected, most likely attributable to mandatory neurologic assessment after the procedure. No pronounced structural valve deterioration was found during 2-year follow-up. Continued long-term surveillance remains important.

Determinants of Reverse Remodeling of the Left Atrium Following Transaortic Myectomy
Conclusions Left atrial volume decreases significantly following surgical relief of left ventricular outflow tract obstruction. Early changes likely reflect lower LA pressure due to gradient relief and abolishment of mitral regurgitation, and late reduction suggests continued reverse remodeling.

Risk of Intraatrial Thrombi After Thoracoscopic Ablation in Absence of Heparin and Appendage Closure
Conclusions Thoracoscopic ablation of AF can be associated with a risk of left atrial appendage thrombus formation and possibly also stroke. With administration of heparin during the ablation, followed by occlusion of the left atrial appendage as a part of the procedure, this risk can be effectively reduced.

Surgical Ablation of Atrial Fibrillation in the United States: Trends and Propensity Matched Outcomes
Conclusions Contemporary utilization of SA is increasing across all operative categories. Performance of SA is accompanied by a 30-day reduction in mortality and stroke. These findings further refine our understanding of the role of SA in the treatment of AF.

Long-Term Risk of Ischemic Stroke After the Cox-Maze III Procedure for Atrial Fibrillation
Conclusions This multicenter study showed a low incidence of perioperative and long-term postoperative ischemic stroke/TIA after CM-III. Although general risk of ischemic stroke/TIA was reduced, patients with CHA2DS2-VASc score 2 or greater had a higher risk compared with score 0 or 1. Complete left atrial appendage excision may be an important reason for the low ischemic stroke rate.

Does Surgical Ablation Energy Source Affect Long-Term Success of the Concomitant Cox Maze Procedure?
Conclusions Concomitant CM procedures performed with cryothermal energy alone or combined with bipolar radiofrequency ablation are safe and exceedingly effective. The association of cryothermal energy alone with higher rates of sinus rhythm and stroke reduction should be investigated further.
