Background-Mitral valve (MV) repair is preferred over replacement in clinical guidelines and is an important determinant of the indication for surgery in degenerative mitral regurgitation (MR). Yet, the level of evidence supporting current recommendations is low, and recent data cast doubts on its validity in the current era. Accordingly, the aim of the present study was to analyze very long-term outcome after MV repair and replacement for degenerative MR with a flail leaflet. Methods-MIDA is a multicenter registry enrolling patients with degenerative MR with a flail leaflet in 6 tertiary European and US centers. We analyzed the outcome after MV repair (n=1,709) and replacement (n= 213), overall, by propensity score matching and by inverse probability-of-treatment weighting. Results-At baseline, patients undergoing MV repair were younger, had more comorbidities and were more likely to present with a posterior leaflet prolapse than those undergoing MV replacement. After propensity score matching as well as after inverse probability-of-treatment weighting, the 2 treatments groups were balanced and absolute standardized differences were usually below 10%, indicating adequate match. Operative mortality (defined as a death occurring within 30 days from surgery or during the same hospitalization) was lower after MV repair than after replacement, both in the entire (1.3 vs 4.7%; p<0.001) and in propensity-matched population (0.2% vs 4.4%; p<0.001). During a mean follow-up of 9.2 years, 552 deaths were observed, of which 207 were of cardiovascular origin. Twenty-year survival was better after MV repair than after MV replacement, both in the entire (46% vs 23%, p<0.001) and in matched population (41% vs 24%, p<0.001). Similar superiority of MV repair were obtained in patients' subsets based on age, sex or any stratification criteria (all p<0.001). MV repair was also associated with reduced incidence of reoperations and valve-related complications.Conclusions-Among patients with degenerative MR with a flail leaflet, referred to mitral surgery, MV repair was associated with lower operative mortality, better long-term survival and fewer valve-related complications compared to MV replacement.

In patients undergoing cardiac surgery, intravenous paracetamol in combination with tramadol provides effective pain control.

In our experience, ASCP was a safe technique for thoracic aorta surgery allowing complex aortic repairs to be performed with good results in terms of hospital mortality and neurologic outcomes. The fact that there was no difference between the two groups suggests that moderate systemic hypothermia (26 degrees C) appears to be a safe and sufficient tool for brain protection. Moreover, the well known hypothermia-related side effects may be avoided.

Endovascular repair represents an alternative, minimally invasive treatment, particularly suitable for use in patients with traumatic aortic injuries. The decision of whether to provide immediate emergency treatment or to delay treatment should be based on the lesion characteristics on imaging and clinical findings. The durability of treatment seems to be related to the absence of alteration to the aortic wall at the extremities.

Patients with long-standing AF and rheumatic heart disease have a very high prevalence of atrial amyloidosis. Amyloid deposition is more frequent in left than in right atrial appendage and correlates with AF duration and female gender. Amyloid deposition could constitute an additional histological feature in the structural remodeling of atria during long-standing AF, at least in rheumatic valve disease. Persistence of AF might play a pivotal role in promoting amyloid deposition.
