BACKGROUND: The aim of this study was to present our experience in the treatment of post-myocardial infarction ventricular septal defect and examine the various risk factors. METHODS: This is a retrospective study. From January 2010 to December 2018, 20 patients underwent an urgent/emergency surgical repair of post-myocardial infarction ventricular septal defect. RESULTS: The mortality in our group of patients was 45 %. Non-survivors compared to the survivors were all in cardiogenic shock (p=0.0098), had an emergency/salvage operation (p=0.0055), preoperative mechanical ventilation (p=0.0081), shorter time between intraaortic balloon pressure insertion and surgery (p=0.0115), shorter median time between ventricular septal defect and surgery, postoperative renal replacement therapy (p=0.0498), and more patients had a residual effect (p=0.0022). In multivariate analysis, preoperative mechanical ventilation (p=0.0001), postoperative renal replacement therapy (p=0.0021) and residual defect (p=0.0000027) were shown to be strong predictors for hospital mortality. CONCLUSION: This analysis showed that post-myocardial infarction ventricular septal defect repair is a devastating complication and preoperative mechanical ventilation, postoperative renal replacement therapy and residual defect were identified to be the predictors of mortality. Initial stabilization of the patients, when it is possible, and a delayed repair, may improve the outcome of these patients. [ABSTRACT FROM AUTHOR]

OBJECTIVES: Mechanical circulatory support is an established therapy in end-stage heart failure. The EUROMACS registry was created to promote research in these patients. The aim of this report was to present our 12 year experience with the durable mechanical circulatory support devices and compare it with the EUROMACS registry. METHODS: Data from the entire EUROMACS registry from January 2011 to April 2019 were included (4704 implantations in 4410 patients). During the 12 years of our experience, until April 2019,125 mechanical support devices were implanted, in 122 patients. We compare patients' characteristics, operative data and results with the EUROMACS registry and we report the major complications during the observational period. RESULTS: Primary end-point (death) occurred in 40 (32.8 %) patients in our cohort during the followup period, representing the survival rate 75 %, 68 %, and 58 % for 6, 12, 24 months respectively, which compares favourably with the data, reported by the EUROMACS registry, the survival 66 % and 53 % after 1 and 2 years respectively. Cerebrovascular accident occurred in 7 %, a bleeding event in 32 %, significant infection (driveline) in 78 % and a device malfunction in 13 % of the patients. Forty-three patients underwent a heart transplant with hospital and long-term mortality of 11.6 % and 14 % respectively. CONCLUSION: Mechanical circulatory support is a valuable therapeutic option with excellent survival rates, nevertheless it is associated with clinically significant complications rates. The direct comparison between our cohort and the EUROMACS registry showed that early implantation strategy and mini invasive approach may improve survival rates and decrease postoperative complications.

BACKGROUND: The purpose of this study is to report our experience in performing transapical (TA) TAVR with a balloon-expandable valve only by cardiac surgeons, with on site interventional cardiology support. METHODS: A retrospective review of 97 consecutive patients that underwent TA TAVR due to severe symptomatic aortic stenosis was performed from 2012 to 2016. Median follow-up time was 20.5 months. Preoperative risk factors and postoperative outcomes were evaluated using Valve Academic Research Consortium-2 definitions. RESULTS: All patients were high risk with a mean Euroscore of 7.28±7.77. Five year and 30-day mortality were 9.3 % and 1.1 %, respectively. Ninty six (98.9 %) of the patients had no or mild paravalvular leak seen by transesophageal echocardiography after implantation. Device success was 91.8%. Postoperatively there was a significant increase of the ejection fraction (50.8±7.1 % preoperatively vs 53.1±7.7 % postoperatively, p=0.009) and reverse remodeling of the left ventricle (left ventricular end-diastolic diameter preoperatively 50.8±7.1 mm vs 49.2±8.1 mm postoperatively, p=0.031). CONCLUSION: Our experience demonstrates that TA TAVR can be performed only by cardiac surgeons, with on site interventional cardiology support safely and successfully with low and comparable postoperative mortality and rate of complications.

INTRODUCTION: Implantation of a total artificial heart is an alternative to durable biventricular assist device support in selected patients. We present our initial experience with the implantation of the SynCardia total artificial heart (TAH) in three patients. The first patient, was the first SynCardia (TAH) implantation in the Visegrad Four (V4) countries. METHOD: Three patients with severe refractory end stage biventricular heart failure listed for heart transplant were indicated for SynCardia TAH implantation. RESULTS: We present in details the perioperative and postoperative outcomes of these patients. The first and the third patient, after 195 and 126 days of TAH support respectively, had a successful heart transplants, the second patient died on 11th postoperative day. The cause of death was brain bleeding due to ruptured undiagnosed brain aneurysm. CONCLUSION: SynCardia TAH is an alternative therapy in patients with end-stage biventricular heart failure waiting for heart transplantation. The SynCardia TAH with pulsatility resembles the physiologic circulation, improves the condition of the patients and increases survival compared to the biventricular assist devices. It is an intermediate step until the development of genetically modified animal hearts, engineered bioartificial hearts or hearts from induced pluripotent stem cells that would replace the failing heart in the patients with end-stage heart disease (Tab. 2, Fig. 1, Ref. 27).
