Minimally Invasive Surgery

January 30, 2019
Hata and colleagues performed a propensity score-matched analysis comparing 85 pairs of patients who underwent either minimally invasive mitral valve repair or chordal-sparing replacement for degenerative mitral valve regurgitation. Freedom from major adverse cardiac and cerebrovascular events after seven years was similar between the groups.

Malvindi and colleagues assessed the outcomes of aortic clamping strategies, either transthoracic cross-clamp (TTC, n = 165) or endoaortic balloon occlusion (EAO, n = 93) for patients undergoing minimally invasive mitral valve surgery. Endoaortic balloon occlusion was more commonly used for redo surgery (2% of TTC cases versus 12% of EAO cases).

Prakash P. Punjabi of the Imperial College in London, UK, presents the argument for conventional approaches for the treatment of mitral valve disease.

Enoch Akowuah of the James Cook Hospital in Middlesbrough, United Kingdom, discusses key aspects of the UK Mini Mitral Trial and sets the scene for a debate on median sternotomy versus minithoracotomy for degenerative mitral valve disease.

The authors, using the STS/ACC TVT Registry, analyzed the the occurrence of patient-prosthesis mismatch (PPM) in 62,215 patients enrolled between 2014 and 2017. They found that severe and moderate PPM occurred in 12% and 25% of patients, respectively.

This study analyzed the cost-effectiveness of TAVR versus SAVR in 3110 intermediate-risk aortic stenosis patients from the PARTNER-2 trial. Using a Markov model, the authors found that TAVR is economically dominant from the perspective of lifetime cost-effectiveness in the US healthcare system.

Grant and colleagues studied short- and midterm outcomes for 639 matched pairs of patients who underwent mitral valve surgery by either sternotomy or a minimally invasive approach at three UK institutions between 2008 and 2016. Patients were included even if they underwent concomitant tricuspid valve surgery or ablation for atrial fibrillation.

Torsten Doenst of the University Hospital Jena in Germany presents the argument for minimally invasive techniques over median sternotomy in the treatment of mitral valve disease.

This video demonstrates the utility of cadaveric simulation in preparation for a complete portal robotic carinal resection and reconstruction on extracorporeal membrane oxygenation.

An interesting randomized controlled trial asserting robustly that endoscopic harvesting of saphenous vein is: (1) better for leg dehiscence and (2) at least noninferior for MACE compared to the conventional open "full touch" method.
