Papillary muscle relocation and mitral annuloplasty in ischemic mitral valve regurgitation: midterm results.
2014
Objectives The surgical approach for ischemic mitral regurgitation remains unclear. Many studies are in favor of adding the subvalvular procedure to mitral annuloplasty to reduce recurrent mitral regurgitation. This study reports the clinical and echocardiographic outcomes of papillary muscle relocation combined with mitral annuloplasty.Methods From 2003, 115 patients with severe ischemic mitral regurgitation who underwent papillary muscle relocation plus nonrestrictive mitral annuloplasty and coronary artery bypass grafting were retrospective analyzed. Patients' mean age was 52 ± 12.8 years, New York Heart Association class III or IV was 71%, and preoperative left ventricular ejection frac…
Thoracic research scholarship 1988: pulmonary thromboendarterectomy for chronic thromboembolic pulmonary hypertension at the University of California…
1990
At the University of California, San Diego pulmonary thromboendarterectomy (PTE) has emerged as an effective measure in the treatment of chronic thromboembolic pulmonary hypertension. Unresolved emboli become organized by incorporation into the vascular wall and may form strictures, webs, bands and/or membranous occlusions and cause pulmonary hypertension refractory to medical treatment. When pulmonary vascular resistance exceeds 300 dyn.sec.cm-5 and the vascular wall changes are located to begin at or proximal to the lobar artery level, surgery is indicated. The operation is performed using cardiopulmonary bypass, deep hypothermia and periods of circulatory arrest. The dissection of each s…
Intraoperative neuroprotective drugs without beneficial effects? Results of the German Registry for Acute Aortic Dissection Type A (GERAADA).
2013
OBJECTIVES: Cerebral protection during acute aortic dissection Type A (AADA) surgery may be affected by perfusion strategies and ischaemic protective drugs. METHODS: We analysed the impact of intraoperative barbiturate, steroid and mannitol use and adjunctive cerebral perfusion (CP), on 30-day mortality and new postoperative mortality-corrected permanent neurological dysfunction (PNDmc) in the German Registry for Acute Aortic Dissection Type A. RESULTS: Two thousand one hundred and thirty-seven AADA patients were registered over a 4-year period. The overall 30-day mortality was 16.9%, and the overall rate of PNDmc was 10.0%. A total of 48% of patients received no neuroprotective drugs (cont…
Implantation of Gore-Tex chordae on aortic valve leaflet to treat prolapse using "the chordae technique": surgical aspects and clinical results.
2008
Background Repair of prolapsed aortic valve leaflets has been considered a challenging technique for cardiac surgeons. In this paper we describe our surgical approach, "the chordae technique." It consists of the correction of aortic cusp prolapse by shortening the free margin length and of an adjustment of the leaflets coaptation height by anchoring the prolapsing cusp to the aortic wall at the sinotubular junction level. Methods Between February 2003 and December 2006, 26 patients with one or more prolapsed aortic leaflets underwent surgical repair using the new approach. The mean age of patients was 55 ± 10 years. There were 10 (38.5%) patients with grade II aortic valve regurgitation, 4 …
Mid-term results of bicuspid aortic valve repair guided by morphology and function assessment.
2016
Bicuspid aortic valve (BAV) is frequently associated with aortic insufficiency (AI) due to cusp disease and/or aortic root dilatation. Based on functional classification and morphology, a systematic surgical approach was used for aortic valve repair (AVr).From 2004 to 2014, 152 consecutive patients (mean age 55 ± 7 years) with BAV underwent AVr with or without concomitant aortic root surgery. Cusp pathology was treated with central plication in 60 (39.5%) patients, free edge reinforcement in 45 (29.6%), triangular resection in 28 (18.4%) and pericardial patch in 19 (12.5%). Aortic root dilatation was corrected with valve sparing reimplantation in 65 patients. Mean follow-up was 68 ± 36 mont…
Evaluation of gastric intramucosal pH during and after pediatric cardiac surgery.
1997
Objectives: In adult patients, intramucosal pH (pHi) has been advocated to detect postoperative complications. The purpose of our study was to evaluate this technique in pediatric patients during and after cardiac surgery. Methods: Thirty-five infants (age: 5 days to 15 years, median 1.8 years; and weight: 3.2‐32 kg, median 9.8 kg) were studied. pHi was measured before cardiopulmonary bypass (CPB), after 30 min of CPB, prior to weaning off CPB, at intensive care unit arrival, and 6, 12, 24, 48 and 72 h after surgery. Results: There were no complications related to the tonometer. A pathologically low pHiB 7.32 was found during surgery in less than 17%, at intensive care unit arrival in 83% a…
Early outcomes and complications following cardiac surgery in patients testing positive for coronavirus disease 2019: An international cohort study
2021
The outbreak of severe acute respiratory syndromecoronavirus-2, the cause of coronavirus disease 2019 (COVID-19) in December 2019 represented a global emergency accounting for more than 2.5 million deaths worldwide.1 It has had an unprecedented influence on cardiac surgery internationally, resulting in cautious delivery of surgery and restructuring of services.2 Understanding the influence of COVID-19 on patients after cardiac surgery is based on assumptions from other surgical specialties and single-center studies. The COVIDSurg Collaborative conducted a multicenter cohort study, including 1128 patients, across 235 hospitals, from 24 countries demonstrating perioperative COVID-19 infection…
Pseudomembranous invasive tracheobronchial aspergillosis.
2004
Invasive aspergillus tracheobronchitis is a rare infectious complication in severely immunocompromised patients who are generally neutropenic with haematological diseases, AIDS, or after solid organ transplantation. However, a few cases have been reported with no apparent severe compromise in the host defences.1 Aspergillus tracheobronchitis varies from localised tracheobronchitis …
Survival and reinterventions after isolated proximal aortic repair in acute type A aortic dissection.
2018
OBJECTIVES Conventional treatment for acute type A dissection is the replacement of the ascending aorta. This study demonstrates the results of a conventional approach with isolated proximal repair combined with concomitant endovascular procedures. METHODS Replacement of the ascending aorta with or without an open distal anastomosis was defined as isolated proximal repair and was performed in 562/588 patients between January 2004 and June 2017. A total of 68% were DeBakey type I and 32% were DeBakey type II aortic dissections. Concomitant procedures were thoracic endovascular aortic repair (3.6%); visceral, renal and iliac stents (2%); and peripheral bypasses (1.1%). Mean follow-up was 4.6 …
C-reactive Protein Levels After Esophagectomy Are Associated With Increased Surgical Trauma and Complications.
2020
With the introduction of minimally invasive esophagectomy, postoperative complications rates have decreased. Daily laboratory tests are used to screen patients for postoperative complications. The course of inflammatory indicators after esophagectomy after different surgical approaches has not been described yet. The aim of the study was to describe the postoperative C-reactive protein (CRP) and leukocyte levels after different surgical approaches for esophagectomy and relate it to postoperative complications.Between 2010 and 2018, 217 consecutive patients underwent thoracoabdominal esophagectomy with gastric conduit reconstruction. Blood tests to assess CRP and leukocytes were performed da…
