Leiomyosarcoma of the Inferior Vena Cava Extending to the Right Atrium and Ventricle

Primary tumors originating from the inferior vena cava (IVC), namely leiomyosarcoma, present significant challenges due to their poor prognostic features, including extensive extension and a substantial tumor burden. In this case, we present a 55-year-old female patient complaining of abdominal discomfort and vague abdominal pain. Additionally, we provide a comprehensive summary encompassing key aspects related to symptomatology, diagnostic approaches, treatment, and prognostic indicators. We also discuss the complexities involved in managing primary tumors of the inferior vena cava, emphasizing the critical significance of adopting a multidisciplinary team-based approach.

Comparison of Heart Team vs Interventional Cardiologist Recommendations for the Treatment of Patients With Multivessel Coronary Artery Disease

IMPORTANCE

Although the heart team approach is recommended in revascularization guidelines, the frequency with which heart team decisions differ from those of the original treating interventional cardiologist is unknown.

OBJECTIVE

To examine the difference in decisions between the heart team and the original treating interventional cardiologist for the treatment of patients with multivessel coronary artery disease.

DESIGN, SETTING, AND PARTICIPANTS

In this cross-sectional study, 245 consecutive patients with multivessel coronary artery disease were recruited from 1 high-volume tertiary care referral center (185 patients were enrolled through a screening process, and 60 patients were retrospectively enrolled from the center's database). A total of 237 patients were included in the final virtual heart team analysis. Treatment decisions (which comprised coronary artery bypass grafting, percutaneous coronary intervention, and medication therapy) were made by the original treating interventional cardiologists between March 15, 2012, and October 20, 2014. These decisions were then compared with pooled-majority treatment decisions made by 8 blinded heart teams using structured online case presentations between October 1, 2017, and October 15, 2018. The randomized members of the heart teams comprised experts from 3 domains, with each team containing 1 noninvasive cardiologist, 1 interventional cardiologist, and 1 cardiovascular surgeon. Cases in which all 3 of the heart team members disagreed and cases in which procedural discordance occurred (eg, 2 members chose coronary artery bypass grafting and 1 member chose percutaneous coronary intervention) were discussed in a face-to-face heart team review in October 2018 to obtain pooled-majority decisions. Data were analyzed from May 6, 2019, to April 22, 2020.

MAIN OUTCOMES AND MEASURES

The Cohen κ coefficient between the treatment recommendation from the heart team and the treatment recommendation from the original treating interventional cardiologist.

RESULTS

Among 234 of 237 patients (98.7%) in the analysis for whom complete data were available, the mean (SD) age was 67.8 (10.9) years; 176 patients (75.2%) were male, and 191 patients (81.4%) had stenosis in 3 epicardial coronary vessels. A total of 71 differences (30.3%; 95% CI, 24.5%-36.7%) in treatment decisions between the heart team and the original treating interventional cardiologist occurred, with a Cohen κ of 0.478 (95% CI, 0.336-0.540; P = .006). The heart team decision was more frequently unanimous when it was concordant with the decision of the original treating interventional cardiologist (109 of 163 cases [66.9%]) compared with when it was discordant (28 of 71 cases [39.4%]; P < .001). When the heart team agreed with the original treatment decision, there was more agreement between the heart team interventional cardiologist and the original treating interventional cardiologist (138 of 163 cases [84.7%]) compared with when the heart team disagreed with the original treatment decision (14 of 71 cases [19.7%]); P < .001). Those with an original treatment of coronary artery bypass grafting, percutaneous coronary intervention, and medication therapy, 32 of 148 patients [22.3%], 32 of 71 patients [45.1%], and 6 of 15 patients [40.0%], respectively, received a different treatment recommendation from the heart team than the original treating interventional cardiologist; the difference across the 3 groups was statistically significant (P = .002).

CONCLUSIONS AND RELEVANCE

The heart team's recommended treatment for patients with multivessel coronary artery disease differed from that of the original treating interventional cardiologist in up to 30% of cases. This subset of cases was associated with a lower frequency of unanimous decisions within the heart team and less concordance between the interventional cardiologists; discordance was more frequent when percutaneous coronary intervention or medication therapy were considered. Further research is needed to evaluate whether heart team decisions are associated with improvements in outcomes and, if so, how to identify patients for whom the heart team approach would be beneficial.

Para-aortic arch abscess secondary to Staphylococcus aureus pneumonia

Staphylococcus aureus is a relatively common pathogen causing pneumonia in the community, hospital ward and intensive care unit. Although pneumonia is responsible for significant morbidity and mortality, especially in elderly and immunocompromised patients, it is usually uncomplicated and resolves without complications. The case of a woman who developed a para-aortic abscess after a community-acquired S aureus pneumonia infection is presented. A number of diagnostic imaging modalities were used to reach the diagnosis. This complication has not been reported previously and it is likely secondary to suppurative lymphadenitis of a station 5 or 6 node. The patient was successfully managed nonsurgically with computed tomography-guided drainage and intravenous antibiotics.

Intracardiac shunt with hypoxemia caused by right ventricular dysfunction following pericardiocentesis

Significant hypoxemia can result from right-to-left intracardiac shunting through a patent foramen ovale, an atrial septal defect or a ventricular septal defect. Pulmonary embolus, congenital heart disease and pericardial tamponade are well-recognized causes of right-to-left shunting. However, right-to-left shunting can also follow pericardiocentesis. A case of profound hypoxemia caused by right ventricular hypokinesis precipitated by pericardial tap is reported. This under-recognized entity can be responsible for significant morbidity in the critical care setting. The clinical presentation, natural history, diagnosis and treatment of hypoxemia caused by intracardiac shunt following pericardiocentesis are discussed.

Tricuspid valve disruption and ventricular septal defect secondary to blunt chest trauma

An unusual case of blunt thoracic injury is presented, highlighting the importance of echocardiography in the assessment of patients with suspected cardiac trauma.

Ventricular septal defect secondary to penetrating trauma without pericardial effusion

Incidence of penetrating cardiac trauma is on the rise. With improved trauma care, an increasing number of these patients arrive at the hospital alive. An unusual case of penetrating cardiac trauma is presented that highlights the importance of thorough echocardiographic assessment of such patients.

Blunt and penetrating cardiac trauma: a review

Cardiologists' expertise in managing traumatic heart disease will be increasingly sought as the incidence of both firearm and motor vehicle accidents soars. Knowledge of mechanisms of injury, as well as appropriate use of diagnostic tools, will aid in rapid recognition of complications related to cardiac injury.

Pericarditis presenting and treated as an acute anteroseptal myocardial infarction

Early recognition and treatment of acute myocardial infarctions have been accepted as improving patient mortality. With the popular use of thrombolytic therapy, it is necessary to rule out contraindications and to consider other causes for ST segment elevation. A unique patient experiencing chest pain with marked and localized ST segment elevation in the anteroseptal leads is presented. He was treated with thrombolytic therapy. Subsequent investigations ruled out the diagnosis of myocardial infarction and confirmed the diagnosis of pericarditis. Although the patient's outcome was uncomplicated, physicians are urged to consider the diagnosis of pericarditis before using thrombolytic therapy to avoid life-threatening complications.

Echocardiographically guided pericardiocentesis - the gold standard for the management of pericardial effusion and cardiac tamponade

BACKGROUND

The conventional surgical pericardiotomy and blind needle-puncture pericardiocentesis using a subxiphoid approach have been reported to have only moderate success rates and to be associated with unacceptably high rates of morbidity and mortality. More recently, echocardiographically guided pericardiocentesis was reported to improve considerably the likelihood of success and the safety of this procedure.

OBJECTIVE

To evaluate the efficacy and safety of echocardiographically guided pericardiocentesis in the authors' institution.

PATIENTS AND METHODS

A series of consecutive patients who underwent percutaneous pericardiocentesis at the Hamilton General Hospital, Hamilton, Ontario, from June 1994 to December 1998.

RESULTS

Forty-one patients underwent a total of 46 echocardiographically guided pericardiocentesis procedures. The procedure was successful in 100% of attempts. Clinical complications occurred in two (5%) patients: one patient with known coagulopathy developed hemothorax and one patient developed purulent pericarditis several days after the procedure. There were no deaths, and no patient required urgent referral for surgical management.

CONCLUSIONS

Echocardiographically guided pericardiocentesis is safe and effective, and is the method of choice for therapeutic and diagnostic drainage of pericardial effusions. While echocardiographically guided pericardiocentesis was described originally at centres with large volumes of patients with clinically significant pericardial effusions and with extensive experience in using this technique, similar high success and low complication rates were attained at an institution with relatively low numbers of patients requiring pericardial drainage.

Acquired left ventricular to right atrial communication and complete heart block following nonpenetrating cardiac trauma

Intracardiac shunts are uncommon cardiac lesions caused by blunt chest trauma. A very unusual case is reported of a young male with an acquired left ventricular to right atrial communication and complete heart block cause by nonpenetrating chest trauma. The left ventricular to right atrial fistula was diagnosed noninvasively by transthoracic and transesophageal echo-Doppler examination and the findings were confirmed by left ventriculography and by the intraoperative findings.

Right atrial myxoma originating from the eustachian valve

An unusual case of multiple right atrial myxomas arising from the interatrial septum and the Eustachian valve is reported. The literature contains reports of only one other patient with a right atrial myxoma originating from the Eustachian valve.
