<p class="p1"><span class="s1"><strong>Background:</strong> Star GK valves were widely used in China, and we studied the clinical follow-up results of patients with Star GK valve implants for more than one year. </span></p><p class="p1"><span class="s1"><strong>Methods:</strong> Clinical data were collected from those patients who had Star GK valve implants for over one year. Patients were divided into three groups: (1) AVR group: received aortic valve replacement surgery. Based on the valve model this group was further sub-divided into two groups: 21A group, and 23A group; (2) MVR group: received mitral valve replacement surgery. Based on the valve model this group was further sub-divided into three groups: 25M group, 27M group, and 29M group; (3) DVR group: received combined replacement surgeries including AVR + MVR. According to postoperative follow-up time these patients were divided into two groups: 1-year group and 3-year group. Follow-up data were collected by telephone, outpatient visits, or correspondence. Clinical data were aggregated by professional data scientists to conduct independent analyses. </span></p><p class="p1"><span class="s1"><strong>Results:</strong> 959 patients were included in the study following Star GK valve implant. Follow-up after 1 year found that thrombosis occurred in 4 cases, hemorrhage in 15 cases, left heart failure in 13 cases, paravalvular leakage in 5 cases, and death due to cardiac causes in 2 cases. </span></p><p class="p1"><span class="s1"><strong>Conclusion:</strong> The long-term efficacy of Star GK valve implants was satisfactory with low incidence of valve-related complications, and following Star GK valve implant, valve and blood were highly compatible and blood component damage was minor. Very low incidence rate of thrombosis was observed following Star GK valve implant, however, attention should be paid to adjust the anticoagulation intensity. </span></p>

Objectives: To evaluate results of minimally invasive aortic valve replacement surgery through right thoracotomy with some techinque improvements in Hanoi Heart Hospital. Methods: Surgery was performed via a small right thoracotomy in the second intercostal space. The third rib was detached by a wedge-shaped way using sternum saw. Cannulation approaches were central or peripheral depended on patients’ condition. Preoperative, perioperative, early results and follow-up data was collected and analysed. Results: There was 48 patients in the research. Mean age was 60,94 ± 11,53 (25-82), and 52,1% was male. 29,2% of patients had peripheral vascular disease. 22,9% underwent central arterial cannulation. 3 patients (6,3%) had pericardial adhesion. There was no early mortality, 2 patients had redo surgery due to excess bleeding. 1 patients had intestinal infarction. Mean follow-up time was 13,4 months. 91,3% of patients had NYHA I. 1 patients was dead due to intracerebral hemorrhage. Conclusions: With some improvements in techniques, minimally invasive aortic valve replacement surgery through right thoracotomy gave good early and midterm results in our center.

Valve Replacement Surgery

The clinical study is reported of the results of heart valve replacement surgery with a new pyrolytic carbon tilting disc prosthesis manufactured in Italy. From March 1977 to January 1981, at the «De Gasperis» Cardiosurgery Center, this prosthesis has been implanted in 644 patients: 283 for mitral valve replacement, 240 for aortic valve replacement, and 121 for the replacement of both mitral and aortic valves. To have a sufficiently long period of post-surgery follow-up, we considered the results of 207 patients (124 cases of isolated mitral valve replacement and 83 cases of isolated aortic valve replacement), who underwent surgery consecutively from March 1977 to December 1979. The hospital mortality was 10.5% for mitral valve replacement and 4.8% for aortic valve replacement. All patients who were discharged from hospital, except 2, were subjected to clinical, electrocardiographic, phonocardiographic, ecocardiographic and radiological checks. The average follow-up period was approximately 20 months: clinical results were satisfactory. The probability of survival, expressed by actuarial curve, was, three years after surgery, 94% for patients who underwent mitral valve replacement and 97.5% for those who underwent aortic valve replacement. The probability of embolism was, three years after surgery, 8.5% for patients with mitral replaced and 5% for aortic. Even if further confirmations are needed the mortality rate and the probability of embolism related to this new prosthesis, are lower, over the same period of follow-up, than that found in the groups of patients who underwent valve replacement surgery, at the same Center, with Starr-Edwards and Björk-Shiley prostheses. The phonocardiographic and ecocardiographic characteristics of this new prosthesis were also investigated.

Abstract Background Infective endocarditis (IE) is a major cause of morbidity and mortality among persons who inject drugs (PWID) and rates have increased during the current opioid epidemic. Severe cases may require valve replacement surgery (VRS). These patients are typically younger with fewer comorbidities than those who undergo VRS for other indications. This study was designed to examine the prognosis for these cases. Methods The University of Vermont Medical Center is a 562-bed academic medical center. A retrospective cohort included all cases of IE among PWID who underwent VRS between November, 2009 and December, 2015. The cohort intentionally included surgeries performed prior to 2016 in order to provide sufficient follow-up time. Outcomes included survival, readmission, complications, adherence to follow-up, length of stay, rate of repeat VRS, microbiology, and recurrent bloodstream infections. Results The cohort included 31 patients. 80% were male and the median age was 31. The valves replaced or repaired included 18 aortic, 10 mitral, 9 tricuspid, and 1 pulmonic (7 patients had two valves involved). Organisms included Staphylococcus aureus (48%), Streptococcus spp. (22%), and Enterococcus (13%). The median length of stay for the index admission was 35 days. To date, at least 38% of the cohort has died. The median survival for those who died was 337 days (0–2,224). Adherence with initial outpatient follow-up visit was only 50%, with others either canceling or missing appointments. 39% followed up with infectious diseases and 39% with cardiothoracic surgery. 29% never followed up. The readmission rate was 51%, and 22% of the cohort was readmitted more than three times. 48% had a repeat bloodstream infection, 73% of which were with a different organism than the index infection. The rate of repeat VRS was 31%. Conclusion Our observational data reveal a high mortality rate with poor adherence to follow-up and a high rate of readmission among this rural cohort of PWID who have VRS for IE. The major limitation of this work is the passive follow-up from the medical record. The high mortality and morbidity of this disease suggests that more intensive, multispecialty post-operative care is needed for PWID who are treated surgically.

Valve Replacement Surgery

Background: Atrial fibrillation (AF) is the most common arrhythmia with adverse clinical outcomes. Aortic valve replacement (AVR) is one of the most frequently performed cardiac surgeries, although there is scarce evidence on arrhythmic outcomes. We aimed to evaluate AF during the first year post- isolated aortic valve replacement surgery and its clinical, analytical, and echocardiographic predictors. Methods: Severe aortic stenosis patients with no prior atrial fibrillation submitted to isolated aortic valve replacement surgery were included in our study, of which 316 remained in sinus rhythm and 24 developed AF. We performed logistic regression searching for AF predictors and a longitudinal comparison between pre and post-operative echocardiographic data. Results: Postoperative AF (POAF), diabetes, and follow-up indexed Left Atrium Diameter (iLAD) were significantly higher in the group of patients developing AF. POAF and iLAD were independent AF predictors at follow-up. No differences between groups were found regarding baseline and follow-up echocardiographic data except for indexed Left Ventricle End-diastolic Diameter (LVED), which failed to decrease after surgery in the AF group. Conclusions: POAF and iLAD independently predicted AF at 1 year following isolated AVR surgery in aortic stenosis patients with no AF history. iLVED did not decrease significantly at follow-up in AF patients, possibly reflecting adverse ventricular remodeling.
