Association Between Adaptive Servo-Ventilation Therapy and Renal Function.

Teruhiko Imamura, Masakazu Hori, Nikhil Narang, Koichiro Kinugawa,

Cardio-renal syndrome is a challenging clinical entity to manage, and is often associated with increased morbidity and mortality. We hypothesized that adaptive servo-ventilation (ASV), non-invasive positive pressure ventilation that ameliorates systemic/pulmonary congestion, may improve renal function in patients with symptomatic heart failure complicated by the cardio-renal syndrome. Patients with symptomatic ... Read more >>

Prognostic Value of Ventricular-Arterial Coupling After Transcatheter Aortic Valve Replacement on Midterm Clinical Outcomes.

Hiroaki Yokoyama, Futoshi Yamanaka, Koki Shishido, Tomoki Ochiai, Shohei Yokota, Noriaki Moriyama, Yusuke Watanabe, Shinichi Shirai, Norio Tada, Motoharu Araki, Fumiaki Yashima, Toru Naganuma, Hiroshi Ueno, Minoru Tabata, Kazuki Mizutani, Kensuke Takagi, Masanori Yamamoto, Shigeru Saito, Kentaro Hayashida, ,

Background Ventricular-arterial coupling predicts outcomes in patients with heart failure. The arterial elastance to end-systolic elastance ratio (Ea/Ees) is a noninvasively assessed index that reflects ventricular-arterial coupling. We aimed to determine the prognostic value of ventricular-arterial coupling assessed through Ea/Ees after transcatheter aortic valve replacement to predict clinical events. Methods ... Read more >>

Primary Cardiac Angiosarcoma Accompanying Cardiac Tamponade.

Masakazu Hori, Teruhiko Imamura, Shuhei Tanaka, Hiroshi Ueno, Shuji Joho, Kazuaki Fukahara, Shinya Kajiura, Koichiro Kinugawa,

A de novo cardiac malignant tumor is rare and sometimes challenging to diagnose. We encountered a 67-year-old man without any medical history complaining of dyspnea on effort. On admission, his hemodynamics were deteriorated due to cardiac tamponade, which was improved by percutaneous drainage of 1,200 mL pericardial effusion, showing 11.0 ... Read more >>

The Clinical Importance of Hyponatremia in Patients with Left Ventricular Assist Devices.

Anthony J Kanelidis, Teruhiko Imamura, Benjamin Yang, Tamari A Miller, Murtaza Bharmal, Gene Kim, Gabriel Sayer, Nir Uriel,

Hyponatremia is associated with increased morbidity and mortality in heart failure (HF) patients. The implication of hyponatremia during left ventricular assist device (LVAD) therapy remains unknown. In this retrospective study, consecutive LVAD patients implanted between April 2014 and March 2018 were stratified by the presence of hyponatremia (serum sodium <135 ... Read more >>

Teruhiko Imamura, Akira Oshima, Nikhil Narang, Hiroshi Onoda, Shuhei Tanaka, Ryuichi Ushijima, Mitsuo Sobajima, Nobuyuki Fukuda, Hiroshi Ueno, Koichiro Kinugawa,

<h4>Background</h4>Baseline and post-procedural elevations in serum troponin-T levels are associated with increased morbidity and mortality following transcatheter aortic valve replacement (TAVR). However, the prognostic impact of change in serum troponin-T level following TAVR remains unknown.<h4>Methods</h4>Among the patients with severe aortic stenosis who underwent TAVR, those with baseline serum troponin-T level ...

Optimal Therapeutic Strategy Using Sacubitril/Valsartan in a Patient with Systolic Heart Failure and Chronic Kidney Disease - An Initial Case Report in Japan.

Teruhiko Imamura, Masakazu Hori, Koichiro Kinugawa,

Sacubitril/valsartan has demonstrated its prognostic advantageousness over enalapril in patients with heart failure with a reduced ejection fraction. However, the optimal therapeutic strategy using sacubitril/valsartan in real-world practice, particularly among a Japanee cohort, remains uncertain. A 75-year-old man with systolic heart failure and chronic kidney disease was administered sacubitril/valsartan. Plasma ... Read more >>

Consensus Report on Destination Therapy in Japan - From the DT Committee of the Council for Clinical Use of Ventricular Assist Device Related Academic Societies.

Koichiro Kinugawa, Yasushi Sakata, Minoru Ono, Shinichi Nunoda, Koichi Toda, Norihide Fukushima, Akira Shiose, Shogo Oishi, Dai Yumino, Teruhiko Imamura, Miyoko Endo, Yumiko Hori, Koichi Kashiwa, Kaoruko Aita, Hiroyuki Kojin, Yutaka Tejima, Yoshiki Sawa,

Destination therapy (DT) is the indication to implant a left ventricular assist device (LVAD) in a patient with stage D heart failure who is not a candidate for heart transplantation. The implantable LVAD has been utilized in Japan since 2011 under the indication of bridge to transplant (BTT). After almost ... Read more >>

Naoya Kataoka, Teruhiko Imamura, Takahisa Koi, Keisuke Uchida, Koichiro Kinugawa,

<i>Background and objectives:</i> Current guidelines criteria do not satisfactorily discriminate responders to cardiac resynchronization therapy (CRT). QRS amplitude is an established index to recognize the severity of myocardial disturbance and might be a key to optimal patient selection for CRT. <i>Materials and Methods:</i> (1) Initial R-wave amplitude, (2) S-wave amplitude, ...

How to Estimate the Optimal Heart Rate in Patients with Heart Failure with Preserved Ejection Fraction.

Toshihide Izumida, Teruhiko Imamura, Takuya Fukui, Takatoshi Koi, Yohei Ueno, Masakazu Hori, Masaki Nakagaito, Shuhei Tanaka, Naoya Kataoka, Ryuichi Ushijima, Makiko Nakamura, Mitsuo Sobajima, Nobuyuki Fukuda, Hiroshi Ueno, Koichiro Kinugawa,

Ideal heart rate (HR), particularly for those with heart failure with preserved ejection fraction (HFpEF), remains unknown. We hypothesized that cardiac output would be maximum when the overlap between E-wave and A-wave at the trans-mitral flow is "zero" in the Doppler echocardiography. We retrospectively investigated the association among the overlap ... Read more >>
