Mukherjee","doi":"10.19080/JOCCT.2018.11.555825","DOIUrl":"https://doi.org/10.19080/JOCCT.2018.11.555825","url":null,"abstract":"The most common pathophysiologic cause of Mitral Stenosis (MS) is rheumatic disease [1]. Generally Left Ventricular (LV) systolic function is well preserved in isolated MS. LV chamber typically is normal or small. However, coexisting Mitral Regurgitation (MR), aortic valve disease, ischaemic heart disease, systemic hypertension, cardiomyopathy all may be responsible for elevation of Left Ventricular End Diastolic Pressure (LVEDP) [2]. Left Ventricular (LV) dysfunction has been described in pure Mitral Stenosis (MS), which may be a due to change in interaction between right and left ventricles, myocardial fibrosis or a chronic decrease in preload [3]. Even with normal ejection fraction (indicating preserved global left ventricular function), there can be impairment in long-axis function (measured by tissue Doppler echocardiography) [4]. Altered LV long-axis movement has been shown to be a sensitive indicator of early myocardial dysfunction. Atrial fibrillation has shown to cause impairment of LV function. Pulsed-wave Doppler tissue velocities have been proven to be a good tool for assessment of long-axis ventricular shortening and lengthening. In the echocardiographical assessment of LV function, the Ejection Fraction (EF), Tissue Doppler Imaging (TDI), Doppler strain, and 2D strain have been widely used [5]. EF is the most widely used index of contractile function, but due to the visual component, assessment of endocardial excursion is subjective and has high inter-observer variability [6]. TDI and Doppler strain are characterized by limitations of angle dependence, limited spatial resolution and deformation analysis in one dimension [7]. 2D strain is a novel technique which evaluates LV systolic functions more objectively and quantitatively, and does not have the limitations seen in EF, TDI, and Doppler strain; thus, it has become more commonly used in recent years [8]. In the diagnosis of LV dysfunction due to MS, some studies have shown EF, TDI, and Doppler strain to be useful however there is paucity of data. There are also very few studies combining both conventional and 2D strain echo for evaluation of LV systolic function after successful Percutaneous Balloon Mitral Valvotomy (PBMV). There are also lack of evidences comparing LV systolic function before and after the above-mentioned procedure in patients with severe rheumatic MS.","PeriodicalId":73635,"journal":{"name":"Journal of cardiology & cardiovascular therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48730629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Five months after BIV-ICD implantation, the LVEF had improved to 55%. During routine lung cancer screening a left upper lobe mass measuring 1.5x1.1 cm was found. A biopsy was done, and further histology showed a spiculated squamous cell carcinoma. Given his frail clinical condition it was decided that he was to receive radiotherapy only, for which the AICD generator had to be relocated away from the radiation target. To extend the DF-4 ICD lead, we used a specialized 27-cm-long DF-4 Y splitter/adaptor (Medtronic Model 5019 HV Splitter/Adaptor) which allowed enough length to extend the DF-4 ICD lead from upper chest to Left Upper Quadrant (LUQ) of the abdomen. The procedure was tolerated well by the patient, after which he made a satisfactory recovery with no postoperative complications. The patient then, in due course, underwent radiotherapy for his lung cancer. Our technique of using a DF-4 Y Splitter/Adaptor as a DF4 lead extender could be used in any patient needing an extender, such as those in which the leads had to be tunneled to the contralateral side, and not only for patients requiring radiotherapy.","PeriodicalId":73635,"journal":{"name":"Journal of cardiology & cardiovascular therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48401841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Child had not undergone cardiac catheterization before glenn surgery. She was severely symptomatic for the past one and half years with class III symptoms and worsening cyanosis. On examination she weighed 15kg, her vital parameters were within normal limits and she had severe cyanosis (oxygen saturation 65%) and grade III clubbing. Cardiovascular examination showed single S1 and S2 with no murmur. Patient was planned for diagnostic catheterization to find out the cause for severe desaturation and to assess the suitability for final stage of palliation. Investigation showed hemoglobin of 18gm% with 60% hematocrit and normal biochemical parameters. Patient cardiac catheterization was done after heparinisation at 100U/kg. It showed functional glenn shunt with adequate branch pulmonary arteries and a large levoatrial cardinal vein (10.4mm) connecting left brachiocephalic vein to left atrium (Figure 1), (Video 1). Atrial pressures were 13mmHg, while mean pulmonary artery pressure was 16-17mmHg. It was decided to plug the vein presently with Amplatzer Vascular Plug II (AVPII). Left subclavian vein access was taken with a 5Fr short sheath and a super stiff amplatz wire was parked in the Left atrium. Now a 8Fr long cook sheath was exchanged over the wire and a 14mm AVP II was deployed at the junction of brachiocephalic vein with LACV. Repeat contrast injection showed device in place with no flow across the plug (Figure 2). Saturation on table improved to 80%, repeat mean PA pressures were 16-17mmHg. Patient was observed for a day and discharged on medical management (Aspirin and iron) as the high PA pressure precluded from performing fontan completion. Patient reported after 6 months for review, she had class II symptoms and saturated 76-80%. Repeat cardiac cath data to our surprise, showed reduced mean PA pressure of 13mmHg and atrial pressures as 11mm Hg. She underwent successful extra cardiac fontan completion. On follow-up at one month she had no complaints and doing well.","PeriodicalId":73635,"journal":{"name":"Journal of cardiology & cardiovascular therapy","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45405563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
