Background: Surgical scars cause an intra-atrial conduction delay and anatomical obstacles that facilitate the perpetuation of atrial flutter (AFL). This study aimed to investigate the outcome and predictor of recurrent atrial tachyarrhythmia after catheter ablation in patients with prior cardiac surgery for valvular heart disease (VHD) who presented with AFL.Methods: Seventy-two patients with prior cardiac surgery for VHD who underwent AFL ablation were included. The patients were categorized into a typical AFL group (n = 45) and an atypical AFL group (n = 27). The endpoint was the recurrence of atrial tachyarrhythmia during follow-up. A multivariate analysis was performed to determine the predictor of recurrence.Results: No significant difference was found in the recurrence rate of atrial tachyarrhythmia between the two groups. Patients with concomitant atrial fibrillation (AF) had a higher recurrence of typical AFL compared with those without AF (13 vs. 0%, P = 0.012). In subgroup analysis, typical AFL patients with concomitant AF had a higher incidence of recurrent atrial tachyarrhythmia than those without it (53 vs. 14%, P = 0.006). Regarding patients without AF, the typical AFL group had a lower recurrence rate of atrial tachyarrhythmia than the atypical AFL group (14 vs. 40%, P = 0.043). Multivariate analysis showed that chronic kidney disease (CKD) and left atrial diameter (LAD) were independent predictors of recurrence.Conclusions: In our study cohort, concomitant AF was associated with recurrence of atrial tachyarrhythmia. CKD and LAD independently predicted recurrence after AFL ablation in patients who have undergone cardiac surgery for VHD.

The aim – to determine the factors associated with the frequency of hospitalizations for decompensation of heart failure (HF) after cardiac surgery in patients with valvular heart disease. Materials and methods. 235 patients who underwent cardiac surgery for valvular heart disease were examined. During the period from 2014 to 2017, a part of patients (129 people) had no hospitalizations, while 106 people were on inpatient treatment from 1 to 10 times, on average 2.78±1.95. The complex of examination of patients along with physical examination included electrocardiography, echocardiography. Results and discussion. During dynamic observation for 2 years in the group of patients without hospitalization, a progressive statistically significant decrease in the size of the left atrium (LA) and left ventricle (LV) as well as an increase in LV contractility were noted, while in the group of patients after hospitalization such changes were not observed. The dimensions of the chambers of the heart remained practically unchanged for 2 years. Thus, it can be concluded that the more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers. Predictors of hospitalizations for HF are the presence of diabetes mellitus, hypertension and permanent form of atrial fibrillation. Conclusions. The probability of progression of heart failure in patients after cardiosurgical intervention for valvular heart pathology is not affected by sex, age, type of lesion of the valve, etiology of valve damage, indicators of echocardiography. Predictors of hospitalizations for heart faiure in the long-term postoperative period are the presence of diabetes, AF, and AH. The more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers.

Abstract Background Atrial fibrillation (AF) and valvular heart disease (VHD) are both associated with an increased risk of stroke. Outside post-hoc analyses of randomized controlled trials, knowledge on the effectiveness and safety of dabigatran in patients with AF and VHD is scarce. Objectives To compare the risk of all-cause mortality, stroke, and bleeding in patients with AF and VHD treated with dabigatran or a vitamin K antagonist (VKA). Methods All Danish residents are provided a unique personal identification number enabling cross-linking of data from Danish nationwide registries. We identified all patients with AF and VHD initiating treatment with dabigatran or VKA between the 22nd of August 2011 and the 31st of December 2014. We defined VHD as aortic stenosis/regurgitation, mitral regurgitation, bioprosthetic heart valves, mitral-, and aortic valve repair. Outcomes were all-cause mortality, stroke, and bleeding. 2-year standardized absolute risks were calculated from cause-specific Cox regression models with death as competing risk. Results In total, 599 (27.3%) and 1,596 (72.7%) patients initiated treatment with dabigatran and VKA. The 2-year standardized absolute risk of all-cause mortality (95% CI) for VKA was 27.6% (25.1% to 30.1%) and 25.4% (21.8% to 29.0%) for dabigatran with a corresponding absolute risk difference of −2.2% (−6.3% to 1.9%) (Figure 1). The 2-year standardized absolute risk of stroke for VKA was 3.4% (2.3% to 4.5%) and 3.9% (2.2% to 5.5%) for dabigatran with a corresponding absolute risk difference of 0.5% (−1.6% to 2.5%). Lastly, the 2-year standardized absolute risk of bleeding for VKA was 8.2% (6.6% to 9.7%) and 7.6% (5.1% to 10.1%) for dabigatran with a corresponding absolute risk difference of −0.5% (−3.4% to 2.4%). Figure 1 Conclusions In this nationwide cohort study, we found no significant difference in the risk of all-cause mortality, stroke, or bleeding in patients with AF and VHD when comparing VKA to dabigatran.

Background and Aims: Coronary artery disease (CAD) constitute a major cause of cardiovascular morbidity and mortality worldwide with an enormous burden on healthcare resources. Prevalence and pattern of CAD in patients of rheumatic and non-rhemuatic valvular heart diseases varies widely with limited data on optimal strategies for diagnosis and treatment.Methods: This study includes 97 patients with rheumatic and non-rheumatic valvular heart disease who underwent coronary angiogram (CAG) before cardiac surgery. Patients were divided into two groups based on rheumatic heart disease (RHD) & non-rheumatic disease (Non-RHD) and correlate the patterns of CAD.Results: Out of 97 patients, 22 (22.6%) patients were found to have significant CAD. In patients with non-rheumatic origin CAD was common (15 patients, 68.1%) as compared to rheumatic origin (7 patients, 31. 8%). In rheumatic origin, the prevalence was 7(12.2%) out of 57 patients while in non-rheumatic origin, was 15(37.5%) out of 40 patients. In RHD group, all patients with CAD were found to have single vessel diease (SVD) while, in non-RHD group, 11 patients (73.3%) had SVD, 3 patients (16.7%) had double vessel disease (DVD) and one patient (5.6%) had triple vessel disease (TVD).Conclusions: Prevalence of CAD is higher in patients with non-RHD in comparison to those with RHD. We also found SVD to be the most common pattern of CAD in both rheumatic and non-rheumatic valvular heart disease.

ABSTRACT  Valvular heart disease accountsfor 10% to 20% of all cardiac surgical procedures in the United States. The decision to intervene, as well as the type of intervention for a patient with severe valvular heart disease, should be based on an individual risk-benefit analysis. Once a patient is considered a candidate for cardiac surgery, a comprehensive patient evaluation of medical conditions and comorbidities helps improve operative outcomes and minimize the mortality rate. Patients with severe valvular heart disease with chronic heart failure at times, progressing to malnutrition. Patients undergoing cardiac surgery experience a systemic inflammatory response, which contributes to acute organ injury leading to a higher incidence of comorbidities and worse malnutrition. Therefore, preoperative risk and nutritional assessment are critical in performing safe cardiac surgical procedures. We report a case of a malnourished 17-year-old man with multiple valvular heart disease with optimal preparation, including good nutritional status leading to good outcome of complex cardiac surgery even in the high risk patients. Keywords             : valvular heart disease, malnutrition, perioperative assessmentCorrespondence   : [email protected]

Abstract Australian Aboriginal and Torres Straight Islanders (ATSI) are noted to have a higher burden of chronic health conditions. However, there is a paucity of data on obstructive sleep apnoea (OSA) in this population. In this retrospective study, we evaluated the clinical and polysomnographic (PSG) characteristics of ATSI and non-ATSI adult patients who underwent diagnostic PSG between 2011 and 2015. There were a total of 3078 patients. Of the total, 403 (13%) were of ATSI origin. Among those of ATSI origin, 61% were male and 39% females, while among the non-ATSI cohort, 66% were males. The median age was 47.8 years in ATSI and 51.5 years in the non-ATSI cohort. In the combined cohort, body mass index was more than 30 kg/m2 (61%), hypertension (14.4%), diabetes (17.8%), and heart disease (23.3%). The ATSI patients had higher rates of class III obesity (27 vs. 15%), hypertension (26 vs. 14%), cardiac disease (34 vs. 23%), and diabetes (37 vs. 17%). Among all the study participants, the PSG confirmed 83.7% of the patients had an apnoea–hypopnea index (AHI) more than 5/h, mild (AHI 5–15/h) in 28.4%, moderate (AHI 15–30/h) in 22.3%, and severe (AHI > 30/h) in 33.0%. Among the ATSI patients, 46% had severe OSA. The median total AHI value was higher in the ATSI population (25, interquartile range [IQR]: 11–58) compared to the non-ATSI (17, IQR: 7–36), and in rural/remote population (19, IQR: 8–42) compared to urban (17, IQR: 7–37). This trend was similar for NREM (non-rapid eye movement)-AHI and REM (rapid eye movement)-AHI scores, although statistically significant difference was found only with ATSI status. In the combined cohort the probability of (OR = 1.62, 95% CI: 1.32–2.00, p < 0.001) of severe OSA was 62% higher in individual with hypertension, however, when stratified by ATSI status, the association was only significant in the non-ATSI population (OR = 1.53 95% CI: 1.21–1.94, p < 0.001). The odds of severe AHI was also significantly associated with heart disease (1.37; 95% CI: 1.14,1.63, p < 0.001), diabetes (1.74; 95% CI: 1.43,2.10; p < 0.001) and smoking (1.28; 95% CI: 1.09,1.50, p = 0.0023) in the overall study cohort. In both ATSI and non-ATSI patients, body mass index, neck circumference, sleep efficiency, wake after sleep onset, and respiratory arousal index were significantly higher and independently associated with severe AHI.
