Acute Surgical Pulmonary Embolectomy: A 9-Year Retrospective Analysis

Acute pulmonary embolism is a substantial cause of morbidity and death. Although the American College of Chest Physicians Evidence-Based Clinical Practice Guidelines recommend surgical pulmonary embolectomy in patients with acute pulmonary embolism associated with hypotension, there are few reports of 30-day mortality rates. We performed a retrospective review of acute pulmonary embolectomy procedures performed in 96 consecutive patients who had severe, globally hypokinetic right ventricular dysfunction as determined by transthoracic echocardiography. Data on patients who were treated from January 2003 through December 2011 were derived from health system databases of the New York State Cardiac Surgery Reporting System and the Society of Thoracic Surgeons. The data represent procedures performed at 3 tertiary care facilities within a large health system operating in the New York City metropolitan area. The overall 30-day mortality rate was 4.2%. Most patients (68 [73.9%]) were discharged home or to rehabilitation facilities (23 [25%]). Hemodynamically stable patients with severe, globally hypokinetic right ventricular dysfunction had a 30-day mortality rate of 1.4%, with a postoperative mean length of stay of 9.1 days. Comparable findings for hemodynamically unstable patients were 12.5% and 13.4 days, respectively. Acute pulmonary embolectomy can be a viable procedure for patients with severe, globally hypokinetic right ventricular dysfunction, with or without hemodynamic compromise; however, caution is warranted. Our outcomes might be dependent upon institutional capability, experience, surgical ability, and careful patient selection

Aneurysm of an autologous aorta to right coronary artery reverse saphenous vein graft presenting as a mediastinal mass: a case report

Aneurysmal dilation of saphenous vein grafts is a relatively rare complication of the now common surgical procedure of coronary artery bypass graft (CABG) surgery. The true prevalence of this condition is not clear, however, literature review by Jorgensen et. al. between 1975 and 2002 revealed only 76 published cases. [1] Recent review of literature, utilizing OVID (search terms: saphenous vein, aneurysm, graft, pseudoaneurysm, coronary bypass) suggests a significantly higher prevalence with 14 such cases published in a variety of multinational journals during the period of 2006 to April 2007. The causes of this dramatic increase is likely multifactorial, however, in the author's opinion, likely reflects the increased sophistication and utilization of cross sectional imaging modalities. Regardless of the true prevalence of the condition, there is little debate that the potential for serious morbidity and mortality in this patient population is significant, and that increased detection and discussion of viable therapeutic options is critical. [1] Therefore, we present a case report and discussion of a patient with symptomatic cardiac ischemia, found to have a large saphenous vein graft aneurysm (SVGA) on coronary CTA

Continuous invasive hemodynamic monitoring using steerable guide catheter to optimize mitraclip transcatheter mitral valve repair: A multicenter, proof-of-concept study.

OBJECTIVES: We report our multicenter experience on continuous hemodynamic monitoring using exclusively the steerable guide catheter (SGC) during MitraClip repair. BACKGROUND: Left atrial pressure (LAP) and V-wave are useful to evaluate MitraClip repair but no simple method of continuous monitoring exists. METHODS: From 11/2016 to 8/2017, 74 patients from four centers with symptomatic moderate-severe to severe mitral regurgitation (MR), underwent MitraClip NT repair with continuous hemodynamic monitoring via the SGC. Real-time LAP/V-wave changes were compared with transesophageal echocardiography (TEE). When mitral stenosis was suspected, transmitral gradients were verified by invasive hemodynamics. Clinical and echocardiographic outcomes were determined. RESULTS: Mean age was 78 ± 10 years and STS score 9.1 ± 11.0%. Pathology included leaflet prolapse/flail (45%), restriction (35%), and mixed (20%). Number of clips averaged 1.7 ± 0.7 per case. There was a significant reduction in LAP (21 ± 10 to 15 ± 7 mmHg, P \u3c 0.0001) and V-wave(37 ± 19 to 24 ± 10 mmHg, P \u3c 0.0001) post MitraClip, but the decrease was less in patients with atrial fibrillation (P \u3c 0.05). Transmitral gradient significantly increased from 2.0 ± 1.2 to 4.0 ± 1.7 mmHg (P \u3c 0.0001). Paradoxical increases in LAP and V-wave despite MR reduction were observed in three cases requiring MitraClip repositioning or retrieval to avoid stenosis. Follow-up averaged 5.0 ± 2.9 months and was 100% complete. KCCQ improvement was significant and MR reduction to CONCLUSIONS: Continuous hemodynamic monitoring using the SGC complements TEE to assess and optimize MitraClip repair in real-time. Further validation is necessary but this feature may be part of future MitraClip and other transcatheter mitral repair systems
