Left heart vent

Kan Nawata, Minoru Ono
Cardiac surgeries have become complicated, although the procedures have been sophisticated as well as anesthetic management and postoperative care. Cardiac surgery team's main concerns include how to preserve cardiac function after aortic cross-clamp and chemical cardiac arrest, which cause myocardial edema and reperfusion injury. These days beating-heart surgery for mitral valve diseases is reported. Patients of mitral disease with low cardiac function due to ischemic cardiomyopathy or dilated cardiomyopathy as well as patients of mitral disease with functional coronary bypass graft might be good candidates for beating-heart mitral valve surgery, via either median sternotomy or right thoracotomy approach...

Patients with venoarterial extracorporeal membrane oxygenation (ECMO) frequently suffer from pulmonary edema due to left ventricular dysfunction that accompanies left heart dilatation, which is caused by left atrial hypertension. The problem can be resolved by left atrium (LA) decompression. We performed a successful percutaneous LA decompression with an atrial septostomy and placement of an LA venting cannula in a 38-month-old child treated with venoarterial ECMO for acute myocarditis.

OBJECTIVES: The clinical outcome of children with severe acute myocarditis who require mechanical circulatory support is not well known. Therefore, we studied the survival and clinical courses of patients with acute fulminant myocarditis supported by extracorporeal life support (ECLS). METHODS: We performed a retrospective chart review of 13 consecutive children with acute fulminant myocarditis who were treated with ECLS between April 2013 and April 2015. Demographics, initial symptoms, laboratory results, management, clinical courses and last follow-up status were investigated...

BACKGROUND: Patients with chronic heart failure (HF) secondary to left ventricular systolic dysfunction (LVSD) are frequently deficient in vitamin D. Low vitamin D levels are associated with a worse prognosis. OBJECTIVES: The VINDICATE (VitamIN D treatIng patients with Chronic heArT failurE) study was undertaken to establish safety and efficacy of high-dose 25 (OH) vitamin D3 (cholecalciferol) supplementation in patients with chronic HF due to LVSD. METHODS: We enrolled 229 patients (179 men) with chronic HF due to LVSD and vitamin D deficiency (cholecalciferol <50 nmol/l [<20 ng/ml])...

Extracorporeal membrane oxygenation (ECMO) has become one of the often applied mechanical support for acute cardiogenic shock. During venoarterial (VA) ECMO support, left heart decompression should be considered when left ventricular (LV) distension develops with pulmonary edema and LV dysfunction. The aim of this study was to report the results of transaortic catheter venting (TACV), as an alternative venting method, performed during VA-ECMO in patients with acute cardiogenic shock. We retrospectively reviewed the records of seven patients who underwent both ECMO and TACV between February 2013 and February 2014...

Vent vacuum relief valves (VRVs) are used to limit the negative pressure at the ventricular vent catheter tip as well as prevent reversal of blood flow and prevention of air embolism. The purpose of this study was to evaluate the performance of three commercially available ventricular vent valves. The negative pressure at which the vent valve opened was measured at the valve inlet using high-fidelity pressure transducers. Also, the flow rate at which air entrainment occurred due to valve opening was recorded...

Venoarterial extracorporeal membrane oxygenation (VA ECMO) is widely used in patients with cardiogenic shock. Insufficient decompression of the left ventricle (LV) is considered a major factor preventing adequate LV recovery. A 40-year-old male was diagnosed with acute myocardial infarction, and revascularization was performed using percutaneous stenting. However, cardiogenic shock occurred, and VA ECMO was initiated. Severe LV failure developed, and percutaneous transaortic catheter venting (TACV) was incorporated into the venous circuit of VA ECMO under transthoracic echocardiography guidance...

A patient required emergency mitral valve replacement and extracorporeal membrane oxygenation (ECMO) support for acute biventricular failure. The left ventricular (LV) vent inserted via the left upper pulmonary vein induced thrombotic immobilization of a prosthetic valve leaflet, with significant intra-prosthesis regurgitation after ECMO explantation. Therefore, the left atrium was opened on the beating heart during conventional extracorporeal circulation, all prosthesis leaflets were excised and a 29-mm expandable Edwards Sapien prosthesis was inserted within the scaffold of the original prosthesis under direct vision...

We present the case of a woman assisted with veno-arterial extracorporeal membrane oxygenation (v-a ECMO) for postischemic cardiogenic shock, who developed left ventricular thrombosis despite systemic anticoagulation and left ventricular apical venting. We successfully achieved local thrombolysis with tenecteplase administered through the venting cannula to obtain local thrombolysis while reducing systemic effects to a minimum. The procedure was effective with mild systemic bleeding and the patient was successfully weaned off the extracorporeal support a few days thereafter...

We aimed to determine the effect of elective left heart decompression at the time of initiation of central venoarterial extracorporeal membrane oxygenation (VA ECMO) on VA ECMO duration and clinical outcomes in children in a single tertiary ECMO referral center with a large pediatric population from a national referral center for pediatric cardiac surgery. We studied 51 episodes of VA ECMO in a historical cohort of 49 pediatric patients treated between the years 1990 and 2013 in the Paediatric Intensive Care Unit (PICU) of the Royal Children's Hospital, Melbourne...

OBJECTIVES: Left atrial decompression using cardiac catheterization techniques has been described at centers with extracorporeal membrane oxygenation programs. Left atrial decompression can decrease cardiogenic edema, minimize ventricular distension, and allow myocardial recovery. We describe Boston Children's Hospital's experience with percutaneous left atrial decompression techniques, acute outcomes, and clinical impact of left atrial decompression in extracorporeal membrane oxygenation patients...

We describe the case of a 59-year old male patient undergoing combined coronary artery bypass grafting and aortic valve replacement. Manipulation of the heart during cardiopulmonary bypass significantly decreased venous return. Several measures were necessary to improve venous return to a level at which continuation of the procedure was safe. Based on the initial troubles with venous return, we decided to selectively cross-clamp the aorta. This resulted in a large amount of backflow of oxygenated blood from the left ventricle, necessitating additional vents in the pulmonary artery and directly in the left ventricle...

Mitral valve repair is the preferred surgical treatment for mitral regurgitation. Cardiac surgeons must increasingly pursue high-quality mitral valve repair, which ensures excellent long-term outcomes. Intraoperative assessment of a competency of the repaired mitral valve before closure of the atrium is an important step in accomplishing successful mitral valve repair. Saline test is the most simple and popular method to evaluate the repaired valve. In addition, an "Ink test" can provide confirmation of the surface of coaptation, which is often insufficient in the assessment of saline test...

Inverted left atrial appendage is an unusual complication associated with congenital cardiac surgery. Inversion of the left atrial appendage may occur during the surgical procedure or afterwards. The left atrial appendage may invert iatrogenically or as a result of the negative pressure during placement or removal of the left atrial vent or during deairing manoeuvres. This event can be life-threatening because of the mass effect of the atrial appendage within the left atrial cavity.

OBJECTIVES: In this study, we tested the hypothesis that pulmonary artery venting would decrease the incidence of atrial fibrillation after coronary artery bypass surgery. METHODS: This prospective study included 301 patients who underwent complete myocardial revascularization with cardiopulmonary bypass in our department during a 2-year period. The patients were randomly divided into 2 groups: group I included 151 patients who underwent aortic root venting and group II included 150 patients who underwent pulmonary arterial venting for decompression of the left heart...

INTRODUCTION: Veno-arterial extracorporeal life support (ECLS) is a well-established bridging therapy in patients with cardiac or pulmonary failure to maintain organ function and is frequently performed in patients who are not intubated. However, severly impaired cardiac function can occur pulmonary edemy in these patients, necessitating left ventricular unloading. METHODS AND RESULTS: In this study we report a 37-year old female patient with familiar dilated cardiomyopathy suffering from acute biventricular heart failure...

Extracorporeal membrane oxygenation (ECMO) is an effective respiratory and circulatory support in patients in refractory cardiogenic shock or cardiac arrest. Peripheral ECMO sometimes requires left heart drainage; however, few reports state that pulmonary arterial (PA) venting is required during ECMO support. We present a case of a 14-year-old boy who required PA venting during ECMO support after resuscitation from near-drowning in freshwater. A biventricular assist device with an oxygenator implantation was intended on day 1; however, we were unable to proceed because of increasing of pulmonary vascular resistance from the acute lung injury...

Postoperative pulmonary hypertensive crisis (PHC) caused by an inverted left atrial appendage (ILAA) is a rare complication following cardiac surgery. We present a case of 23 day-old male infant who developed postoperative PHC attacks after undergoing cardiopulmonary bypass (CPB) surgery for repair of the coactation of aorta. A hyperechogenic left atrial mass was detected via bedside transthoracic echocardiography (TTE), which was identified as an ILAA and corrected following repeat surgery. In this case, both the negative pressure in vent catheter and the long left atrial appendage (LAA) with a narrow base led to an irreversible ILAA...
