The medical records of 100 cats with distal aortic thromboembolism were reviewed. The average age was 7.7 years, with the neutered male being the most common signalment (63%). Evidence of preexisting cardiac disease was noted in 11% of the cases. A murmur or arrhythmia was noted in 57% of the cases on presentation. Frequent laboratory abnormalities included elevations in blood glucose, alanine aminotransferase, aspartate aminotransferase, blood urea nitrogen, and creatinine. Radiographic and electrocardiographic abnormalities were common (89% and 85%, respectively). The most frequent, underlying disease was hypertrophic feline cardiomyopathy (58%), with the left atrial size (as measured by M-mode) significantly increased in the majority of cases (mean left atrial-to-aortic ratio, 2.08). The average, long-term survival in the 37% of cases which survived the initial thromboembolic episode was 11.5 months. The remaining cases either died (28%) or were euthanized (35%).

Objectives: Immediate result of PTMC in juvenile (5-12 years) rheumatic mitral stenosis. Study Design: Observational descriptive and retrospective study. Place and Duration of Study: Institute of Cardiology, Multan from 2009 to Jun 2020. Methodology: This is an observational descriptive and retrospective study carried out at Institute of Cardiology, Multan from 2009 to Jun 2020. Patients with clinical evidence of significant mitral stenosis were undergone transthoracic echocardiography. Mitral stenosis was defined as mitral valve area <1.0 cm2 . Mean mitral valve gradient was calculated by mitral valve inflow velocities. Patients with Wilkins score <8 were included. Patients with significant MR, left atrial or atrial appendage clot, infective endocarditis, significant aortic regurgitation or any other indication for bypass surgery were excluded. Patients with Wilkins score >8 were also excluded from the study. Variables recorded on a performa were age, weight, left atrial size, mean mitral valve gradient, preprocedure MR. Reduction of mitral valve mean pressure gradients to less than <50% of the initial value was defined as success (without significant or moderate MR). After the procedure, variables recorded on performa were mean left atrial pressures in mmHg (on angio), mean mitral valve gradients and degree of MR (mild, mild to moderate, moderate or severe MR) on transthoracic echocardiography. Paired t-test of significance (p<0.05) was evaluated using SPSS (version 20). Results: Forty three juvenile patients were included the in the study (2009 to June 2019). Mean age was 10.8 ± 1.4 (range 7-12) years. Mean weight was 28.9 ± 5.2 (20-37) kg. Mean mitral valve gradient (on TTE) before the procedure was 20 ± 6 mmHg. Mean left atrial size and mean area of mitral valve were 42 ± 5 mm and 0.8 ± 0.2 cm2 respectively. Balloon sizes used were 26 mm (n=19) and 24 mm (n=24). After PTMC, mean mitral valve reduced to 7 ± 2 mmHg (p<0.005) and left atrial pressure to 18 ± 7 mmHg. Post procedure transthoracic echocardiography showed 4.7% (n=2/43) patients developed moderate to severe or severe MR. So the success rate was 95.3% (n=41/43). Conclusion: PTMC is safe and effective procedure for juvenile patients with mitral stenosis. Long term follow-up is needed to find out period of re-intervention/surgery free duration from the time of PTMC.

Mechanical Stretching

Electrical cardioversion (ECV) can be effective in restoring sinus rhythm (SR) in the majority of patients with atrial fibrillation (AF). Several factors that predispose to AF recurrences, such as age, AF duration and left atrial size have been used to guide a decision for cardioversion, but increasing evidence suggests that they may be rather poor markers of left atrial structural remodeling that determines the long-term success of a rhythm control strategy. In this context, the use of easily obtainable biomarkers, such as the levels of atrial natriuretic peptide (ANP) and B-type natriuretic peptide (BNP), to predict AF recurrences may be preferable. Since ANP production is associated with the extent of functional atrial myocardium, and both ANP and BNP reflect atrial pressure and mechanical stretching, these peptides are good candidate biomarkers to assess predisposition to AF recurrences. In this review we focus on the pathophysiological mechanisms and the available clinical evidence regarding the prediction of AF recurrences following successful ECV from pre-procedural ANP and BNP levels.

And Function

Left atrium is not a passive heart chamber, because it has a dynamic motion respecting heart cycle and, in accordance with its stretching, it releases atrial natriuretic peptides. Since in the course of certain invasive procedures the size of left atrium may change substantially, its exact measurement and functional characterization are essential. The aim of the present review is to summarize echocardiographic methods for the assessment of left atrial size and functional parameters. Orv. Hetil., 2014. 155(41), 1624–1631.
