Short-term outcomes of minimally invasive mitral valve repair: a propensity-matched comparison

Abstract

When compared with the median sternotomy approach, the RT approach shows comparable results in short-term efficacy and safety. On relatively increasing cardiopulmonary bypass time and operation time, the RT approach shortens the patient's intensive care unit stay and reduces the need for blood transfusion. Pulmonary function may be affected shortly post-surgery in the RT approach, with insignificant difference in haemodynamics.

Long-term results after mitral valve surgery using minimally invasive versus sternotomy approach: a propensity matched comparison of a large single-center series

“…Operating time, cardiopulmonary bypass time and cross-clamp time were longer with MIS than with CS, as has been reported previously [ 6 , 8 , 10 – 12 , 14 , 18 , 20 ] Despite the longer procedural time, there was no difference in the length of ICU stay, and the overall length of hospital stay was shorter in the MIS group. Previous studies have also generally reported shorter ICU or hospital length of stay after MIS compared with CS [ 6 , 8 , 10 – 12 , 14 – 17 , 20 ]. The shorter hospital stay suggests postoperative recovery was quicker in MIS patients and is also consistent with the lower incidence of procedure-related complications seen after MIS compared with CS in our study.…”

“…However, after adjustment for TVR amongst other variables in the present analysis the OR remained significant. Another propensity-matched study has reported a lower rate of dialysis for renal failure after MIS compared with CS [ 13 ], but most studies and meta-analyses have found no difference in these two outcomes between MIS and CS [ 4 , 6 , 14 – 16 , 18 – 20 ]. Nonetheless MIS may be associated with a need for conversion to CS and we find patients with previous right lateral thoracotomy, lung adhesions and peripheral artery disease are at increased risk.…”

Right mini-thoracotomy approach reduces hospital stay and transfusion of mitral or tricuspid valve reoperation with non-inferior efficacy: evidence from propensity-matched study

“…As previous reported, minimally invasive cardiac surgery gains advantages of faster recovery, shorter hospital (9), and our study also showed that the hospital stay and ICU stay of RT group was shorter than the CS group, which could be attributed to minimized incision, shortened CPB time and operation time. However, several studies and our previous study focusing on MV repair have reported that the mini-incision can increase the operation time and CPB time (18)(19)(20)(21). However, with the growing experience in femoral cannulation and surgical technique of mini-incision, the operation time and bypass time was obviously decreased compared with traditional sternotomy, which was burdened with great trouble in detaching and cannulation.…”

First Experiences with MANTA Vascular Closure Device in Minimally Invasive Valve Surgery

“…Minimally invasive valve surgery (MIVS) has been employed since mid-1990s increasingly in cardiac surgery centers worldwide and has been proved by numerous studies to be safe and effective than conventional surgical approaches. 1 Right anterior minithoracotomy (RAMT) for valve surgeries as one of innovative techniques of MIVS has been established next to the development of new technologies for cardiopulmonary bypass (CPB), special surgical and interventional instruments as vascular closure devices (VCDs), and the use of video-thoracoscopic assistance. Surgical access through femoral vessels is the most common used for the establishment of CPB in MIVS.…”
