Frequency of Severe Valvular Disease Caused by Mediastinal Radiation Among Patients Undergoing Valve Surgery in a Community-Based Academic Medical Center
Our goal was to define the prevalence of radiation-induced valvular heart (RIVD) disease among patients undergoing cardiac valve surgery in a community-based, regional academic medical center. Mediastinal radiation is a treatment modality for various hematologic and solid malignancies; however, long-term cardiac complications, including radiation-induced valvular heart disease, can occur years after the radiation treatments.
Mediastinal radiation exposure is an independent risk factor for valvular heart disease often necessitating valve replacement in patients without other risk factors for valve disease.
Between January 1, 1998 and September 1, 2007, we retrospectively analyzed our institution’s cardiac surgical database over a 10 year period and identified 189 consecutive patients ≤ 50 years of age who underwent valve surgery. Using case-control matching, we assessed the prevalence of mediastinal radiation among these young patients with valve disease necessitating surgery and to their matched controls from all patients admitted to the hospital.
Nine individuals (4.8%) were identified as having received previous mediastinal radiation, significantly increased from controls (p<0.0001), and 8 of whom had surgical or pathologic findings consistent with radiation damage. Compared with a matched case-control population, individuals who had severe valve disease and underwent valve replacement had a markedly increased prevalence of prior mediastinal radiation therapy.
In conclusion, cardiologists must remain aware of the potential long term valvular complications in patients treated with mediastinal radiation. Increased surveillance for RIVD may be considered in the decades following radiation therapy.
A 70-year-old patient presented with melena, dyspnea, and generalized weakness. An endoscopy revealed a deep ulcer with a pulsatile clot in the intrathoracic gastric tube that had been previously constructed for esophageal replacement. Shortly thereafter, the patient died of exsanguination secondary to a fistula between the stomach and the right ventricle. This complication presents a unique but deadly cause of gastrointestinal bleeding that mandates swift diagnosis and immediate surgical correction.
Survival and Neurologic Recovery in Patients With ST-Elevation Myocardial Infarction Resuscitated From Cardiac Arrest”
We examined outcomes of patients resuscitated from cardiac arrest owing to ST-segment elevation myocardial infarction (STEMI) and predictors of survival and neurologic recovery.
Immediately after resuscitation from cardiac arrest owing to STEMI, many patients show signs of neurologic impairment, and benefits of percutaneous coronary intervention and subsequent prognosis are not well defined.
Between January 1, 2002, and December 31, 2006, we retrospectively identified consecutive patients resuscitated from cardiac arrest, regardless of time to return of spontaneous circulation (ROSC) and neurologic status, and reviewed the outcomes of those who had STEMI. Mortality and neurologic recovery at discharge and long-term mortality were assessed by individual chart review for those who underwent emergent angiography.
Our study population consisted of 98 patients; 64% survived to discharge, and 92% had a full neurologic recovery. Predictors of survival were shorter time to ROSC, younger age, neurologic status post-resuscitation (alert or minimally responsive), and male sex. Predictors of neurologic recovery included shorter time to ROSC, neurologic status post-resuscitation (alert or minimally responsive), and younger age. Ninety-six percent of patients who were alert post-resuscitation survived. Ninety-three percent of patients who were minimally responsive post-resuscitation survived. Fifty-nine patients were unresponsive post-resuscitation, with 44% survival, of whom 88% had full neurologic recovery. In the unresponsive group, unwitnessed arrest, prolonged ROSC, and older age were associated with increased risk of death, and older age and prolonged ROSC predicted poor neurologic recovery.
When resuscitated patients with STEMI are being evaluated in the emergency department, serious consideration should be given to emergent angiography and revascularization, regardless of neurologic status.
