Project description:An air embolism (AE) is a rare but dreaded complication during endovascular procedures. Current guidance recommends hyperbaric oxygen therapy and aspiration for the management of a venous AE. However, the management of an arterial AE is much less described. We report a case of a 79-year-old man with symptomatic mitral regurgitation who underwent a MitraClip procedure. During the intervention, a massive AE was detected in the ascending aorta on transesophageal echocardiography. The AE was successfully aspirated while the patient remained hemodynamically stable. This report demonstrates the efficacy of an arterial AE's aspiration with a real-time echocardiography recording of the technique.

Project description:Aortic dissection is a rare but potentially fatal complication of percutaneous coronary intervention (PCI). Management strategies of PCI induced dissection are not clearly identified in literature; such occurrences often mandate surgical repair of the aortic root with reimplantation of the coronary arteries. Another trend seen in case reports is the use of coronary-aortic stenting if such lesions permit. Several factors impact the management decision including the hemodynamic stability of the patient; mechanism of aortic injury; size, severity, and direction of propagation of the dissection; presence of an intimal flap; and preexisting atherosclerotic disease. We describe a case of a 65-year-old woman who underwent PCI for a chronic right coronary artery (RCA) occlusion, which was complicated by aortic dissection and pericardial effusion. Our case report suggests that nonsurgical management may also be appropriate for PCI induced dissections, and potentially even those associated with new pericardial effusion.

Project description:BackgroundTranscatheter edge-to-edge mitral valve repair using the MitraClip device is increasingly used for high surgical risk patients with severe mitral regurgitation (MR). Previous guidelines for infective endocarditis prophylaxis prior to dental procedures focused on high-risk patients, but without explicit recommendation for MitraClip recipients. We believe this could be the first reported case to identify Streptococcus oralis as the causative organism.Case presentationAn 87-year-old male with severe MR treated with two MitraClip devices three months prior to index admission, presented with worsening malaise and intermittent chills on a background of multiple comorbid conditions. The patient had dental work a month prior to presentation, including a root canal procedure, without antibiotic prophylaxis. Vitals were significant for fever and hypotension. On physical examination, there was a holosystolic murmur at the apex radiating to the axilla, bilateral pitting edema in the lower extremities, and elevated jugular venous pulsation. A transthoracic echocardiogram showed severe MR with a possible echodensity on the mitral valve, prompting a transesophageal echocardiogram, which demonstrated a pedunculated, mobile mass on the posterior leaflet of the mitral valve. Five blood cultures grew gram positive cocci in pairs and chains, later identified as Streptococcus oralis, with minimum inhibitory concentration to penicillin 0.06 mg/L. Initial empiric antibiotics were switched to ceftriaxone 2 gr daily and subsequent blood cultures remained negative. However, the patient developed pulmonary edema and worsening hemodynamic instability requiring vasopressors. As surgical risk for re-operation was considered prohibitive, the decision was made to continue medical management and comfort-directed care. The patient died a week later.ConclusionsDespite low incidence, infective endocarditis should be included in the differential among MitraClip recipients. The explicit inclusion of this growing patient population in the group requiring prophylaxis prior to dental procedures in the 2020 ACC/AHA valvular heart disease guidelines is an important step forward.

Project description:Transcatheter mitral valve repair (TMVR) is an effective therapy for high-risk patients with severe mitral regurgitation (MR) but heart failure (HF) readmissions and death remain substantial on mid-term follow-up. Recently, right ventricular (RV) to pulmonary arterial (PA) coupling has emerged as a relevant prognostic predictor in HF. In this study, we aimed to assess the prognostic value of tricuspid annular plane systolic excursion (TAPSE) to PA systolic pressure (PASP) ratio as a non-invasive measure of RV-to-PA coupling in patients undergoing TMVR with MitraClip (Abbott, CA, USA). Multicentre registry including 228 consecutive patients that underwent successful TMVR with MitraClip. The sample was divided in two groups according to TAPSE/PASP median value: 0.35. The primary combined endpoint encompassed HF readmissions and all-cause mortality. Mean age was 72.5 ± 11.5 years and 154 (67.5%) patients were male. HF readmissions and all-cause mortality were more frequent in patients with TAPSE/PASP ≤ 0.35: Log-Rank 8.844, p = 0.003. On Cox regression, TAPSE/PASP emerged as a prognostic predictor of the primary combined endpoint, together with STS-Score. TAPSE/PASP was a better prognostic predictor than either TAPSE or PASP separately. TAPSE/PASP ratio appears as a novel prognostic predictor in patients undergoing MitraClip implantation that might improve risk stratification and candidate selection.

Project description:BackgroundTranscatheter edge-to-edge mitral valve repair (TMVr) has been developed as an alternative therapeutic approach to patients with severe mitral regurgitation (MR) at high-surgical risks. Single leaflet device attachment (SLDA) is a well-known complication after the TMVr procedure, while an autopsy case experiencing haemolytic anaemia has been scarcely reported.Case summaryA 79-year-old woman presented with New York Heart Association Class 3 congestive heart failure due to severe MR. The Heart Team planned TMVr using the MitraClip considering a high-surgical risk due to the history of open-chest surgery. The procedure was successful with two clips and a significant reduction of MR was confirmed. On the 12th day after the procedure, congestive heart failure was worsened and a transthoracic echocardiogram revealed severe MR suggestive of SLDA. Blood test showed normocytic anaemia with serum lactate dehydrogenase level elevation and renal function deterioration. We diagnosed as mechanical haemolysis induced by recurrent MR because of a decrease in serum haptoglobin level and the presence of schizocyte in the blood smear. Despite our intensive medical treatment, she died on the 119th day after the procedure. The pathological autopsy demonstrated that the ruptured leaflet was thickened with layered structure and severe fibrosis, while there were no findings of calcification, vegetations, or abscesses.DiscussionSingle leaflet device attachment and subsequent mechanical haemolysis are rare but fatal complications after TMVr with the MitraClip. Not only degenerative MR but also functional MR may be associated with valve leaflet degeneration. A possibility of mechanical haemolysis should be considered when recurrent MR is observed after TMVr.

Project description:IntroductionCatheter-related infections such as exit site infection (ESI) and tunnel infection (TI) are major causes of peritoneal dialysis (PD) discontinuation. For ESI/TI treatment, catheter diversion procedure (CDP) with exit-site renewal for catheter salvage presents an alternative to catheter removal. Nevertheless, CDP capability of improving PD catheter survival remains unclear.MethodsWe retrospectively reviewed our hospital patients who started PD during 2001-2019 (n=148): 33 treated for ESI/TI by CDP (CDP group) and 115 treated for ESI/TI using conservative therapy or none (non-CDP group). A "virtual discontinuation group" was designated for patients in the CDP group who had received PD catheter removal instead of CDP and who had stopped PD. Kaplan-Meier analysis and log-rank test PD were used for intergroup catheter survival comparison. Associations between clinical factors and PD discontinuation or death were examined using Cox proportional hazards regression analyses.ResultsFor patients (76% male, mean age of 61.7±13.0 years), 40 CDP were performed for 33 CDP group patients. Infection-free rates at 30 and 90 days after CDP were, respectively, 90% and 67%. The CDP group PD catheter survival rate was significantly higher than that of virtual discontinuation group (P < .01) and higher than that of the non-CDP group (P = .03). Multivariate analysis revealed independent association of serum albumin concentration (hazard ratio 0.33, 95% confidence interval 0.17-0.67), PD+HD combination therapy (hazard ratio 0.29, 95% confidence interval 0.17-0.49), and CDP (hazard ratio 0.44, 95% confidence interval 0.24-0.80) with PD discontinuation or death.ConclusionResults show that CDP may improve PD catheter survival as an effective and less-invasive surgical treatment for ESI/TI to avoid withdrawal of PD.

Project description:BackgroundThe incidence of pericardial effusion (PE) during radiofrequency catheter ablation (CA) for atrial fibrillation is approximately 1%. PE is a major complication during CA, but there has been limited literature about the perforation site responsible.ObjectiveThis study aimed to retrospectively investigate the characteristics of the procedure and the patients in whom PE developed during CA.MethodsOf 1363 consecutive patients who underwent catheter ablation from January 2015 to June 2019 in Kyorin University Hospital, we reviewed patients who developed PE during CA.ResultsPE during CA occurred in 18 (1.32%) patients (median age, 71 [interquartile range (IQR) 65-77] years, 7 women). The median body mass index was 24 (IQR 20-27). Target arrhythmias for CA of patients with PE include atrial fibrillation (AF) (n = 13, 72%), premature ventricular contraction (n = 2, 11%), ventricular tachycardia (n = 1, 6%), atrial flutter (n = 1, 6%), and orthodromic reciprocating tachycardia (n = 1, 6%). Seventeen patients required pericardiocentesis, resulting in 300 (IQR 192.5-475) mL of drainage. Two patients required emergency surgical repair, and 1 died from aortic dissection. Based on the gas analysis, the drained blood was of venous origin in 47% of the total events and 54% of AF ablation.ConclusionPE caused by a diagnostic catheter in the right heart is not uncommon, even in AF ablation.
