Aortic valve replacement through right anterior mini-thoracotomy in patients with chronic severe aortic regurgitation: a retrospective single-center study.

Background: Aortic valve replacement (AVR) has recently been performed at many centers using a minimally invasive approach to reduce postoperative mortality, morbidity, and pain. Most previous reports on minimally invasive AVR (MiAVR) have mainly focused on aortic stenosis, and those exclusively dealing with aortic regurgitation (AR) are few. The purpose of this study was to investigate early surgical results and review our experience with patients with chronic severe AR who underwent AVR via right anterior mini-thoracotomy (RAT).

Right anterior mini-thoracotomy aortic valve replacement versus transcatheter aortic valve implantation in octogenarians: a single-center retrospective study.

Background: The aim of this study was to compare the early outcomes of octogenarians undergoing minimally invasive right anterior mini-thoracotomy aortic valve replacement (RAT-AVR) with those undergoing transcatheter aortic valve implantation (TAVI) for aortic valve disease.

Methods: In this single-center retrospective study, data were collected from octogenarians before and after RAT-AVR and TAVI between January 2021 and July 2022. Short-term outcomes, including the length of hospital stay, in-hospital mortality, all-cause mortality, and other major postoperative complications, were compared and analyzed.

Unilateral Pulmonary Edema after Minimally Invasive Cardiac Surgery: A Case Report.

Unilateral pulmonary edema after minimally invasive cardiac surgery is a rare, but potentially life-threatening condition. However, the exact causes of unilateral pulmonary edema remain unclear. We experienced aggressive unilateral pulmonary edema followed by redo-resection of recurrent left atrial myxoma through a right mini-thoracotomy.

A Prospective Randomized Trial Comparing Manual Needle Aspiration to Closed Thoracostomy as an Initial Treatment for the First Episode of Primary Spontaneous Pneumothorax.

Background: Variation exists in the initial treatment for the first episode of primary spontaneous pneumothorax (PSP), and no definitive consensus exists due to a lack of high-quality evidence. This study examined the outcomes of needle aspiration and closed thoracostomy in first episodes of PSP requiring intervention.

Methods: This study was a randomized, prospective, single-center trial conducted between December 2015 and August 2016.

Surgical Repair of Aortocaval Fistula Presenting with Cardiogenic Shock.

Aortocaval fistula (ACF) occurs in <1% of all abdominal aortic aneurysms (AAAs), and in 3% to 7% of all ruptured AAAs. The triad of clinical findings of AAA with ACF are abdominal pain, abdominal machinery bruit, and a pulsating abdominal mass. Other findings include pelvic venous hypertension (hematuria, oliguria, scrotal edema), lower-limb edema with or without arterial insufficiency or venous thrombus, shock, congestive heart failure, and cardiac arrest.

A New Root-Strengthening Technique for Acute Aortic Dissection with a Weakened Aortic Root: The Neo-Adventitia Technique.

Background: Dissection flaps in acute type A aortic dissection typically extend into the root, most frequently into the non-coronary sinus (NCS). The weakened root can be susceptible not only to surgical trauma, but also to future dilatation because of its thinner layers. Herein, we describe a new technique that we named the "neo-adventitia" technique to strengthen the weakened aortic root.

Feasibility and Safety of Single-Port Video-Assisted Thoracic Surgery for Primary Lung Cancer.

Background: The feasibility of single-port video-assisted thoracic surgery (SPVATS) for primary lung cancer is not well understood. In this study, we compared SP and multi-port (MP) VATS for the surgical treatment of patients with primary lung cancer.

Methods: Surgical treatment was performed in 181 patients with primary lung cancer at Inje University Haeundae Paik Hospital between June 2012 and December 2015.

Asymptomatic left ventricular hemangioma.

Cardiac hemangiomas are very rare benign neoplasms that are usually asymptomatic. Although there are often found incidentally during echocardiography, other imaging modalities such as computed tomography, magnetic resonance imaging, and coronary angiography are needed to establish a diagnosis. Surgical excision is therefore recommended to confirm the diagnosis and avoid potential complications.

Acute Limb Ischemia and Coronary Artery Disease in a Case of Kimura's Disease.

Kimura disease (KD) is an immune-mediated chronic inflammatory disease of unknown etiology. KD has many complications associated with hypereosinophilia, including various forms of allergic reactions and eosinophilic lung disease. Additionally, hypereosinophilia is associated with hypercoagulability, which may lead to thromboembolic events.

Veno-veno-arterial ECMO support for acute myocarditis combined with ARDS: a case report.

Background: In patients who developed a combined situation of severe acute respiratory distress syndrome with refractory hypoxemia and acute cardiac failure with circulatory collapse, traditional veno-venous or veno-arterial extracorporeal membrane oxygenation approach alone may not be sufficient enough to maintain both an acceptable range of gas exchange and a hemodynamic stability.

Case Report: A 27-year-old male patient was suffering from severe acute respiratory distress syndrome caused by community-acquired pneumonia and acute myocarditis with circulatory shock. After mechanical ventilation for respiratory support, he was in a persistently refractory shock state.

Nafamostat mesilate as a regional anticoagulant in patients with bleeding complications during extracorporeal membrane oxygenation.

Purpose: Anticoagulation is mandatory for extracorporeal membrane oxygenation (ECMO), but systemic heparinization, which has been most widely used as an anticoagulant, has been associated with bleeding complications. The present study reviewed the usefulness and safety of nafamostat mesilate as a regional anticoagulant in patients with bleeding complication during ECMO.

Methods: We retrospectively reviewed the record of 13 cases.

A New Surgical Repair Technique for Ischemic Total Papillary Muscle Rupture.

Papillary muscle (PM) rupture is an emergency surgical condition that may occur after acute myocardial infarction. In patients with compete rupture of the PM, mitral valve replacement is preferred or recommended generally because of unstable vital signs or technical difficulties with successful repair, as compared with patients with partial PM rupture. This case report describes the successful repair of a complete anterolateral PM rupture by using the single PM formation technique with subsequent ring annuloplasty.

Long Segmental Reconstruction of Diffusely Diseased Left Anterior Descending Coronary Artery Using Left Internal Thoracic Artery with Extensive Endarterectomy.

In coronary artery bypass grafting, a diffusely diseased left anterior descending coronary artery (LAD) is an obstacle to achieving complete revascularization, consequently leading to the possibility of a poor prognosis. Long segmental reconstruction with or without endarterectomy is a revascularization method for treating diffusely diseased coronary arteries. Herein, we report a successful case of long segmental reconstruction of a diffusely diseased LAD using a left internal thoracic artery onlay patch after endarterectomy.

Early results of modified aortic-valve sparing partial root replacement in acute type A aortic dissection with an intimal tear in the aortic sinuses.

We describe a modified aortic valve-sparing partial root replacement (AVSPRR) technique for acute type A aortic dissection with an intimal tear (IT) in the aortic sinus. This procedure consists of selective replacement of the sinus containing an IT with a rectangular patch. If an IT exists in any coronary sinus, the coronary button was reimplanted to the neo-sinus and an external wrapping of the noncoronary sinus was added.

Early outcomes of single-port video-assisted thoracic surgery for primary spontaneous pneumothorax.

Background: Recently, single-port video-assisted thoracic surgery (VATS) has been proposed as an alternative to the conventional three-port VATS for primary spontaneous pneumothorax (PSP). The aim of this study is to evaluate the early outcomes of the single-port VATS for PSP.

Methods: VATS was performed for PSP in 52 patients from March 2012 to March 2013.

Three different situations and approaches in the management for anomalous origin of the right coronary artery from the left coronary sinus: case report.

Anomalous origin of the right coronary artery from the left coronary sinus is rare but potentially dangerous if any ischemic signs are present. Multiple therapeutic options were advocated so far. We experienced three different situations and surgical approaches to these anomalies, and reviewed retrospectively.

Giant cell tumor arising from anterior arc of the rib.

A primary giant cell tumor of the rib is very rare. The most common site of a giant cell tumor arising from the rib is the posterior arc. A giant cell tumor arising from the anterior arc of the rib is extremely rare.

A modified root reinforcement technique for acute aortic dissection with a weakened aortic root: a modified Florida sleeve technique and two cases report.

Despite marvelous advances in repair for acute type A aortic dissection over past decades, it remains challenging to repair the aortic root when aortic dissection extended to the sinuses causes the fragile root because of its thinner layers, which are susceptible to suture trauma. Here, we describe a modified Florida sleeve technique to strengthen the weakened aortic root. After mobilization of the aortic root and the coronary arteries, a designed Dacron tube graft was wrapped outside the sinuses as neo-adventitia to reinforce the dissected weakened wall.

Single-port Video-Assisted Thoracic Surgery for Lung Cancer.

Video-assisted thoracic surgery (VATS) is a minimally invasive technique that has many advantages in postoperative pain and recovery time. Because of its advantages, VATS is one of the surgical techniques widely used in patients with lung cancer. Most surgeons perform VATS for lung cancer with three or more incisions.

Stanford type A aortic dissection secondary to infectious aortitis: a case report.

Nowadays, infectious aortitis has become a rare disease thanks to antibiotics, but remains life-threatening. We present a case of a patient with acupuncture-induced infectious aortitis leading to aortic dissection. Chest computed-tomogram scan revealed Stanford type A dissection with pericardial effusion.

An unusual case of left ventricular free wall rupture caused by a silent myocardial infarction.

Left ventricular free wall rupture (LVFWR) is a serious complication of myocardial infarction. It presents with a very high mortality rate and can be rescued by accurate diagnosis and emergency surgery. LVFWR can occur with sudden overt clinical symptoms or present insidiously.

Cox-Maze III procedure with valvular surgery in an autopneumonectomized patient.

Destructive pulmonary inflammation can leave patients with only a single functional lung, resulting in anatomical and physiological changes that may interfere with subsequent cardiac surgeries. Such patients are vulnerable to perioperative cardiopulmonary complications. Herein, we report the first case, to our knowledge, of an autopneumonectomized patient who successfully underwent a modified Cox-Maze III procedure combined with valvular repairs.

Late simultaneous presentation of left ventricular pseudoaneurysm and tricuspid regurgitation after blunt chest trauma.

A 32-yr-old man developed progressive exertional dyspnea 4 yr after blunt chest trauma due to an automobile accident. Two-dimensional echocardiography and computed-tomographic coronary angiography demonstrated a large pseudoaneurysm of the left ventricle and severe tricuspid regurgitation. The patient underwent successful surgical exclusion of the pseudoaneurysm by endoaneurysmal patch closure and repair of the tricuspid valve regurgitation.
